In Japan, automobiles such as private cars, which are widely used, are usually replaced or scrapped before they reach 100,000 km of use for 10 years, and the engines installed in the automobiles are often used. Is exported overseas for reuse or disposal.

The inventor of the present application uses a vehicle engine mounted on or mounted on a vehicle such as a privately-owned passenger car, which is widely used, as a prime mover for driving a generator of an engine-type generator. We focused on the fact that it is possible to provide an expensive engine-type power generator at low cost by using a dedicated engine. However, when the vehicle engine is continuously operated for a longer period of time than the continuous operation time of a normal private car or the like, especially in the case of a used vehicle engine, the operating conditions assumed for the vehicle are met. It becomes a harsh usage condition, and there is a concern that it may break down early or frequently. Therefore, the inventor of the present application uses a plurality of vehicle engines as the prime mover of the engine-type power generation device, and even if a part of the engines fails and stops, the remaining normal vehicle that does not fail. We have come up with the idea that an engine-type power generation device that can continue stable power generation can be provided at low cost by making it possible to continue power generation with a vehicle engine.

On the other hand, if the deterioration state of the component parts is closely monitored over the entire engine-type power generation device, and if necessary, detailed maintenance such as replacement is performed before the component fails. , The cost of maintenance itself may rise, and the cost of engine-powered power generation equipment may rise as a whole. As described above, the vehicle engine is considered to be more prone to failure than other components (for example, a generator) in the engine type power generator, and therefore, it is specialized in the failure of the vehicle engine. If a failure can be found and the entire vehicle engine in which the failure is found can be quickly replaced with another inexpensive vehicle engine, maintenance costs can be kept low and an engine-powered generator can be used. It is possible to reduce the overall cost including the maintenance cost.

The operation control unit 105 is configured to include an arithmetic processing unit such as a CPU and an MPU and a memory device such as a semiconductor memory, and the arithmetic processing apparatus executes the predetermined program to perform the control processing and the like.

The operation control unit 105 does not control the operation of each vehicle engine 101, but the individual operation control is performed by the above-mentioned engine control unit, and the operation control unit 105 controls the engine of each vehicle engine 101. It controls the start and stop of operation for the unit, and outputs a control value for operating at a predetermined number of revolutions. In the case of an engine control unit of a general automobile engine, the number of revolutions is controlled by receiving a control signal corresponding to the amount of depression of the accelerator pedal and adjusting the throttle opening and the like. Instead of the control signal corresponding to the amount of depression of the accelerator pedal, the operation control unit 105 outputs a control value corresponding to a desired rotation speed to the engine control unit of each vehicle engine 101.

The first state measuring instrument 106 is one or more operating states indicating the operating states of one or more vehicle engines 101 in the operating state by the driving control of the driving control unit 105 among the plurality of vehicle engines 101. It is a measuring instrument that measures the first operation state data including the value. The first driving state data is measured for each vehicle engine 101. The operating state value of 1 or more is, for example, at least one of the output (shaft output), the rotation speed (shaft rotation speed), the air-fuel ratio, the fuel supply amount, and the cooling water temperature of the vehicle engine 101. In this case, the measuring instrument is at least one of a shaft output meter, a shaft speed meter, an air-fuel ratio meter, a fuel gas flow sensor, and a cooling water temperature sensor, or two or more of the measuring instruments. It is a combination, and the first operating state data includes the measurement data of the operating state values measured by each of the measuring instruments. Since the shaft output of the vehicle engine 101 can be calculated by multiplying the product of the shaft torque and the shaft rotation speed by a predetermined coefficient, the shaft output meter can be realized by the shaft torque meter and the shaft rotation speed meter. Since the shaft torque meter is not attached to the normal vehicle engine 101, it needs to be provided separately. Therefore, when the shaft output is not used as the operating state value, it is not necessary to provide the shaft torque meter separately. A shaft rotation meter, an air-fuel ratio meter (an oxygen sensor that detects the residual oxygen concentration in the exhaust gas), a fuel gas flow rate sensor, and a cooling water temperature sensor are attached as part of the peripheral devices of the vehicle engine 101. If so, it can be configured using the attached shaft rotation meter, air-fuel ratio meter, flow rate sensor, and temperature sensor. However, since the hydrogen / carbon ratio of methane gas is larger than that of gasoline or light oil, the hydrogen concentration in the exhaust gas of the methane gas engine and the gasoline engine is higher in the methane gas engine. Therefore, when the methane gas engine, which is the vehicle engine 101 of the present embodiment, is manufactured by modifying the gasoline engine for automobiles, the air-fuel ratio meter (in the exhaust gas) attached to the original gasoline engine The detection characteristics of the oxygen sensor that detects the residual oxygen concentration) may change, and if necessary, adjust the attached air-fuel ratio meter or replace it with an oxygen sensor for a methane gas engine separately.

As an example, the first state measuring instrument 106 is configured to include a shaft torque meter, a shaft speed meter, an air-fuel ratio meter, a fuel gas flow rate sensor, and a cooling water temperature sensor, and each measuring instrument is in operation. The output, rotation speed, air-fuel ratio, fuel supply amount, and cooling water temperature of each vehicle engine 101 are continuously measured. The first state measuring instrument 106 further includes an arithmetic processing unit, aggregates the measured values of each measuring instrument for each predetermined unit period (for example, one hour), and sets the average value and the maximum value of each measured value. Three types of minimum statistical values are calculated as first driving state data, and the first driving state data of each vehicle engine 101 being driven is obtained by the data receiving unit of the system 10 described later for each unit period. It is configured to transmit toward 12. The first operating state data is provided with an identification code capable of identifying the engine-type power generation device 100 and the vehicle engine 101, and a transmission date and time. Further, for the vehicle engine 101 that has been stopped during the above unit period, the above three types of statistical values are not calculated, and the operation indicating that the operation has been stopped is shown in the first operation state data. The state value is added. Further, with respect to the vehicle engine 101 whose operation was stopped or restarted in the middle of the unit period, in addition to the above three types of statistical values for a part of the period during which the operation was in progress, the operation was stopped or restarted in the middle. The operating state value indicating that effect and the date and time data are added. As an example, in the calculation of the above three types of statistical values for a part of the period during operation, the output, the number of revolutions, the air-fuel ratio, the fuel supply amount, and the output, the number of revolutions, the air-fuel ratio, and the fuel supply amount in a certain period immediately before the operation is stopped and a certain period immediately after the restart of the operation are calculated. The measured value of the cooling water temperature may differ from the value during steady operation, so it should not be taken into consideration. Each fixed period may be constant regardless of the difference in the vehicle engine 101, or may be preset for each type of the vehicle engine 101.

As another form, the first state measuring instrument 106 uses raw measured values or average values for shorter periods (for example, 1 to 10 minutes) in place of the above three types of statistical values in the first operation. As the state data, it may be periodically (for example, every hour) transmitted to the data receiving unit 12 of the system 10. Further, as another form, the first state measuring instrument 106 is provided with an arithmetic processing unit, and is provided with a predetermined unit period based on the measurement data (for example, the above three types of statistical values) measured by each of the above-mentioned measuring instruments. Every time (for example, 1 hour), it is determined whether the vehicle engine 101 is in a failure state or a quasi-failure state with a high possibility of failure, or a normal state, and the determination result of the arithmetic processing unit is determined. , The operating state value of 1 or more may be set. Further, as another form, when the first state measuring instrument 106 is composed of all the measuring instruments attached as a part of the peripheral device of the vehicle engine 101, it is attached as a part of the peripheral device. The engine control unit is regarded as an arithmetic processing unit included in the first state measuring instrument 106, and the engine control unit independently produces a vehicle engine 101 based on the measurement data measured by each measuring instrument. It may be determined whether the engine control unit is in a failure state or a quasi-failure state with a high possibility of failure, or a normal state, and the determination result of the engine control unit may be the above-mentioned one or more operating state values.

The exhaust gas discharge unit is connected to, for example, the exhaust port of the exhaust manifold of each vehicle engine 101, and the exhaust gas discharged from each vehicle engine 101 is collected and discharged to the outside of the engine-type power generation device 100. Is configured with. An exhaust gas treatment device that removes greenhouse gases such as unburned hydrocarbons and carbon dioxide contained in the exhaust gas, and an exhaust gas treatment device that removes harmful substances such as nitrogen oxides are provided as necessary. It may be provided on the downstream side of the multi-purpose pipe as a part of the exhaust gas discharge portion or as a separate body from the engine type power generation device 100. Further, if necessary, a muffling device for reducing exhaust noise is provided, for example, on the downstream side of the various pipes as a part of the exhaust gas discharging part or as a separate body from the engine type power generation device 100. May be good.

The auxiliary power supply unit is a power source that supplies electric power required for the electric device used in the engine-type power generation device 100, and includes a storage battery (secondary battery). For charging the storage battery, AC power supplied from an external commercial power source or AC power generated by the engine-type power generation device 100 is converted into DC power and used. As the storage battery, a well-known storage battery such as a lead battery or a lithium ion battery can be used. The electric device includes an engine control unit, an ignition plug, a solenoid valve, pumps, etc. mounted on the vehicle engine 101, and the like when the generator 102 needs to be supplied with exciting power from the outside. 102, when the solenoid valve, pumps, etc. are provided in the fuel supply unit 103, the solenoid valve, pumps, etc., the inverter unit 104, and the operation control unit 105 are assumed.

Although the schematic configuration of the engine-type power generation device 100 has been described, details of each component such as the vehicle engine 101 and the generator 102 constituting the engine-type power generation device 100 are realized by using the existing devices. The explanation will be omitted.

The above-mentioned first operating state data measured by the device 106 and engine information including specifications or models of a plurality of vehicle engines 101 are stored separately for the engine type power generation device 100 and the vehicle engine 101. Further, the database unit 11 includes information on the first spare engine including the number of spare vehicle engines owned by one or more first contractors who perform engine-related work including replacement of the vehicle engine 101 and their specifications or models.

Here, when the information or data is stored in the engine type power generation device 100, the vehicle engine 101, the first trader, the user, etc., the information or data is the engine type power generation device 100, the vehicle. It means that the data is stored in the storage device constituting the database unit 11 in a predetermined database structure or format so as to be searchable by the vehicle engine 101, the first company, the user, and the like. The same applies to each of the second vendors described in the second embodiment described later.

The data receiving unit 12 transmits the first operating state data for each vehicle engine 101 from the first state measuring instrument 106 of each engine type power generation device 100 via a data communication network 300 such as the Internet at a predetermined timing described later. It is configured to be received by and stored in the database unit 11. Both the data receiving unit 12 and the first state measuring instrument 106 are provided with a well-known communication interface for communication via the data communication network 300. Writing of the first operating state data into the database unit 11 is performed using the control device of the database unit 11.

The replacement-required engine detection unit 13 is a vehicle engine 101 in a failure state or a quasi-failure state in a plurality of engine-type power generation devices 100 by a predetermined data calculation process based on the first operation state data. It is configured to detect that an engine is included and identify the detected engine that needs to be replaced.

In the first supplier selection unit 14, when the replacement-required engine detection unit 13 detects the replacement-requiring engine in any of the engine-type power generation devices 100, the engine of the engine-type power generation device 100 equipped with the detected replacement-required engine is installed. Based on the information, the information of the first device, and the information of the first trader, the first trader who replaces the detected engine requiring replacement with the spare vehicle engine owned by the first trader by the predetermined data calculation process is selected. It is configured to do.

The first notification unit 15 is mainly required to replace the replacement engine detected by the replacement engine detection unit 13 with respect to the first computer terminal 301 used by the first trader selected by the first trader selection unit 14. Information is configured to be notified or provided via a data communication network 300 such as the Internet. The information required for replacing the engine requiring replacement includes, for example, the name and contact information of the user of the engine-type power generation device 100 equipped with the engine requiring replacement, the first device information such as the address of the installation location, and the replacement required. Contains engine information, including engine specifications or model. In addition to the above, the information required for replacement of the replacement engine may include operation history information such as the cumulative operating time of the replacement engine, first operating state data of the replacement engine, and the like.

As an example, the first notification unit 15 automatically creates a message text of a standard e-mail containing information necessary for exchanging an engine requiring replacement, and uses the message text as the e-mail address specified by the selected first company. It is configured to transmit via the data communication network 300. The first notification unit 15 includes a communication interface for communication via the data communication network 300. The communication interface may be shared with the data receiving unit 12.

The data receiving unit 12, the exchange-required engine detection unit 13, the first supplier selection unit 14, and the first notification unit 15 are similar to the control device of the database unit 11, for example, an arithmetic processing unit such as a CPU and an MPU, and a semiconductor. It is configured to include a memory device such as a memory, and the arithmetic processing unit executes the predetermined program to perform the above-mentioned data processing of each part. A part or all of the control devices of the data receiving unit 12, the replacement engine detection unit 13, the first supplier selection unit 14, the first notification unit 15, and the database unit 11 are composed of a common arithmetic processing unit and a memory device. It may have been done. As an example, this system 10 comprises a database unit 11 and a data receiving unit 12 composed of a server computer having a WEB server function and a database server function that can be accessed from the Internet, and requires replacement engine detection unit 13 and a first supplier. The selection unit 14 and the first notification unit 15 can be configured by a general-purpose computer such as a personal computer having a function of connecting to the Internet.

<Database registration and update>
Next, a method of registering and updating the various information and data stored in the database unit 11 and a timing thereof will be briefly described.

The first device information regarding the user and the installation location for each engine-type power generation device 100 is the operation of the system 10 when a certain engine-type power generation device 100 is newly managed by the system 10. The person in charge (operation person) operates the user interface (keyboard, mouse, display device, etc.) attached to the hardware constituting the system 10 to identify a new power generation device in the engine-type power generation device 100. A code is assigned, and along with the user identification code, the address of the installation location of the engine-type power generation device 100, the name or number of the building, the number of floors, the room number, etc. are stored and registered in the database unit 11 as the first device information. do. When the engine-type power generation device 100 is an existing user, the existing user identification code of the user is used, and when the user identification code is a new user, a new user identification code is assigned to the user identification code. Separate user with user attribute information (name, address, phone number, email address, etc. for individuals, name, department, address, person in charge, contact phone number, email address, etc. for corporations) After registration, the new user identification code will be used. In addition to the above, as a registration item included in the first device information, a trader identification code of the first trader who installed the engine type power generation device 100 or replaced the engine requiring replacement may be added.

To update the first device information, as in the case of registration, when a part of the registered items included in the first device information is changed by the manual operation of the system 10 by the person in charge of operation, the changed part is changed. , If the registered item is overwritten and the registered item included in the first device information (for example, a new trader identification code of the first trader) is added, the item is newly added. And perform the update process.

As for the engine information of the vehicle engine 101, when the first device information of the engine type power generation device 100 equipped with the vehicle engine 101 is registered in the above manner, the operation person in charge performs the same procedure for a plurality of vehicle engines. A new engine identification code is assigned to each of the 101, and along with the power generation device identification code of the engine-type power generation device 100 to be mounted, the manufacturer name of each vehicle engine 101, the distinction between used and new, and the fuel type (this implementation). In terms of form, methane gas or biogas), model, distinction of engine type (methane gas dedicated engine, conversion from gasoline or diesel engine, bifuel engine), exhaust volume, maximum output, standard output during steady operation, standard rotation speed , Standard air-fuel ratio, standard fuel supply amount, standard cooling water temperature, and other attributes, characteristics, and specification values of the vehicle engine 101 are stored and registered in the database unit 11. When the first company is in charge of installing the engine-type power generation device 100, the first company registers the engine information on behalf of the operation person, and the first computer used by the first company. The database unit 11 may be accessed from the terminal 301 via the data communication network 300.

To update the engine information, after the power generation of the engine-type power generation device 100 is started, a part (for example, one) of a plurality of vehicle engines 101 is in a failed state or a quasi-failed state (replacement required engine), and is reserved. It becomes necessary to replace the engine with the vehicle engine 101, and the first trader who made the replacement (not necessarily the same as the first trader when the engine information is registered by the first trader) is the first trader. The engine information of the vehicle engine 101 removed by replacement was deleted by accessing the database unit 11 from the first computer terminal 301 used by one trader via the data communication network 300, and newly introduced by replacement. This is performed by additionally registering the engine information of the vehicle engine 101. Alternatively, without deleting the engine information of the vehicle engine 101 removed by replacement, the information other than the power generation device identification code and the engine identification code in the engine information is replaced with the vehicle engine 101 newly introduced by replacement. It may be replaced with information.

The first operating state data includes the number of vehicle engines 101 mounted on the first state measuring instruments 106 of the plurality of engine-type power generation devices 100 to be managed for the above-mentioned predetermined unit period (for example, for example). Every hour), the data is transmitted to the data receiving unit 12 via the data communication network 300, and the data receiving unit 12 receives the first operating state data for the number of units from each first state measuring instrument 106. Then, the first operation state data for the number of units is stored in the database unit 11 and registered. As described above, each of the first operating state data is attached with an identification code capable of identifying the engine-type power generation device 100 and the vehicle engine 101, and a transmission date and time.

The first operating state data is for a predetermined time (for example, for 1 to 3 days, for 1 to 3 weeks, or 1) for the number of all vehicle engines 101 for the total number of engine-type power generation devices 100 to be managed. ~ 3 months) is saved, and when new first operation state data is added, the first operation state data older than the predetermined time is deleted.

The first trader information is the user interface attached to the hardware constituting the system 10 by the person in charge of operation of the system 10 when a certain first trader becomes a new management target of the system 10. To give a new trader identification code to the first trader, and along with the trader identification code, the attribute information (name, department in charge, address, person in charge name, contact phone number and contact information of the first trader (Email address, etc.) is stored and registered in the database unit 11 as the first trader information. To update the first trader information, as in the case of registration, when a part of the registered items included in the first trader information is changed by the manual operation of this system 10 by the operation staff, the changed part is changed. , Overwrite the registered items and perform the update process.

For the first spare engine information, each first trader assigns a new spare engine identification code to each of the spare vehicle engines owned by each first trader, and the first trader owns the spare vehicle engine. Manufacturer name of each spare vehicle engine, distinction between used and new, fuel type (methane gas or biogas in this embodiment), model, engine type (methane gas dedicated engine, gasoline or diesel engine) Attribute of vehicle engine 101 such as distinction, exhaust volume, maximum output, standard output during steady operation, standard rotation speed, standard air fuel ratio, standard fuel supply amount, standard cooling water temperature, etc. , Characteristics, and specification values are registered by accessing the database unit 11 from the first computer terminal 301 used by each first company via the data communication network 300. The registration is preferably carried out promptly when the spare vehicle engine is newly owned or available for replacement of the engine requiring replacement.

The update of the first spare engine information is the same as at the time of registration when the first trader becomes non-owned due to reasons such as using the spare vehicle engine owned by the first company to replace the engine requiring replacement. This is done by deleting the registration of the spare vehicle engine that is not in possession. Here, the first trader who performed the replacement will additionally register the engine information of the replaced spare vehicle engine as the vehicle engine 101 newly introduced by the replacement, but for the vehicle. As the information other than the power generation device identification code and the engine identification code of the engine information of the engine 101, information other than the trader identification code and the spare engine identification code of the first trader of the first spare engine information can be used.

<Replacement required engine detection process / First supplier selection process>
Next, the basic operations of the replacement-required engine detection unit 13, the first supplier selection unit 14, and the first notification unit 15 of the system 10 will be described with reference to the drawings. FIG. 3 is a flowchart showing an example of a procedure for detecting a replacement engine of the replacement engine detection unit 13. FIG. 4 is a flowchart showing an example of the procedure of the first trader selection process of the first trader selection unit 14.

First, the replacement-requiring engine detection process by the replacement-requiring engine detection unit 13 will be described with reference to FIG. When the replacement-required engine detection process starts, the variables m and n indicating the engine-type power generation device 100 and the vehicle engine 101 are initialized to 1 respectively (step # 11). Here, the correspondence between the variable m (= 1 to M, M is the total number of the engine type power generation device 100) and the power generation device identification code of the engine type power generation device 100, and the variable n in the mth engine type power generation device 100 ( = 1 to N (m), N (m) is the total number of vehicle engines 101 used in the m-th engine-type power generation device 100) and the correspondence between the engine identification code of the vehicle engine 101 are tabulated in advance. Make sure it is stored in a given storage area or that each variable is part of each identification code. As a result, the engine type power generation device 100 and the vehicle engine 101 are uniquely identified by the variables m and n. The variables m and n are for simplifying the explanation of the replacement engine detection process, and the variables m and n are used to specify the engine type power generation device 100 and the vehicle engine 101 in the replacement engine detection process. It is not limited to the method.

Next, the engine information and the first operating state data of the engine-type power generation device 100 and the vehicle engine 101 corresponding to the variables m and n specified at the present time are read from the database unit 11 and temporarily stored in a predetermined state. Save to the area (work area) (step # 12).

Next, the average value, the maximum value, and the minimum value of any one of the measured values of the output, the rotation speed, the air-fuel ratio, the fuel supply amount, and the cooling water temperature of the vehicle engine 101 of the first operating state data read out are 3 For a type of statistical value, the average value of the most recent unit period (for example, 1 hour) is a predetermined reference rate of change (for example, for any one or all of the average values of a plurality of unit periods before it). , ± 20% to 30%), or the range between the maximum and minimum values (= maximum value-minimum value) of the most recent unit period is earlier than that. For any one or all of the maximum and minimum range of multiple unit periods, or both, if there is an increase that exceeds a predetermined reference rate of increase (eg, + 20% to 30%). If there is, it is determined that the vehicle engine 101 is a replacement engine in a failed state or a quasi-failed state (step # 13). Alternatively, in the determination process of step # 13, none of the measured values of output, rotation speed, air-fuel ratio, fuel supply amount, and cooling water temperature is determined to be an engine requiring replacement by the above criteria, but the criteria. If the rate of change and the standard rate of increase are slightly relaxed, if it is determined that the engine requires replacement for two or more of the measured values of output, rotation speed, air-fuel ratio, fuel supply amount, and cooling water temperature, the relevant engine is applicable. The vehicle engine 101 may be determined to be a replacement engine that is in a failed state or a quasi-failed state. Alternatively, in the determination process of step # 13, at least one kind of statistics among the average value, the maximum value, and the minimum value of any one of the measured values of the output, the rotation speed, the air-fuel ratio, the fuel supply amount, and the cooling water temperature. The values are within the preset normal range (eg, standard output, standard speed, standard air-fuel ratio, standard fuel supply, standard cooling water temperature) over the most recent predetermined number of unit periods (for example, 1 hour). On the other hand, when the vehicle engine 11 continuously deviates from the above-mentioned predetermined reference change rate range), it may be determined that the vehicle engine 11 is a failure state engine in a failure state or a quasi-failure state. Further, the determination as to whether or not the engine is in a failed state is not limited to the determination method exemplified above.

The reference change rate and the reference increase rate are determined for each of the output, the rotation speed, the air-fuel ratio, the fuel supply amount, and the cooling water temperature of the vehicle engine 101, but they are different even if they are the same. May be good. Further, the reference change rate and the reference increase rate may be constant regardless of the difference in the vehicle engine 101, or may be preset for each type of the vehicle engine 101.

When it is determined that the engine requires replacement (YES branch) in the determination process of the engine requiring replacement (step # 13), the determination process is performed after performing the first supplier selection process (step # 20) described later. It is determined whether or not the vehicle engine 101 performed is the last vehicle engine (n = N (m)) (step # 14). If it is not determined that the engine requires replacement (NO branch) in the determination process of the engine requiring replacement (step # 13), the process of selecting the first supplier (step # 20) is not performed, and step # 14 is performed. Move to judgment. In the determination of step # 14, if it is not the last vehicle engine (NO branch), the variable n is increased by 1 (step # 15) to the next vehicle engine 101 of the same engine-type power generator 100. In the case of the transition, the processing of steps # 12 to # 14 is repeated, and the engine is the last vehicle (YES branch), the engine-type power generation device 100 that has performed the determination processing is the last engine-type power generation device (m). = M) is determined (step # 16).

In the determination of step # 16, if it is not the last engine-type power generator (NO branch), the variable m is increased by 1 and the variable n is initialized to 1 (step # 17), and the next engine-type power generation is performed. The process shifts to the first vehicle engine 101 of the device 100, the processes of steps # 12 to # 15 are repeated, and if it is the last engine-type power generation device (YES branch), the replacement-required engine detection process ends.

When one replacement-required engine detection process is completed, immediately after the above-mentioned unit period (for example, 1 hour) has elapsed from the start of the previous replacement-required engine detection process, or if the above-mentioned unit period has already passed, immediately. , The next replacement-required engine detection process is started.

Next, in the determination process of step # 13 of the replacement engine detection process, when it is determined that the engine requires replacement (YES branch), the first supplier selection process (step # 20) performed by the first supplier selection unit 14. : See FIG. 3) will be described with reference to FIG. When the first trader selection process starts, the variable k indicating the first trader is initialized to 1, and the variables A (k) and B (k) are initialized to 0, respectively (step # 21). Here, the correspondence between the variable k (= 1 to K, K is the total number of the first traders) and the trader identification code of the first trader is tabulated in advance and stored in a predetermined storage area, or the variable k is Make sure it is part of the vendor identification code. The variable A (k) and the variable B (k) are binary variables each indicating the results of two types of determination processing described later, and there are K variables each. As a result, the first trader is uniquely identified by the variable k. The variable k is for simplifying the explanation of the first trader selection process, and the specification of the first trader in the first trader selection process is not limited to the method using the variable k. Further, the method of temporarily storing the two types of determination results described later is not limited to the method of using the variable A (k) and the variable B (k).

Next, the first device information of the engine-type power generation device 100 corresponding to the variable m currently specified in the replacement-required engine detection process currently pending is read from the database unit 11 and temporarily stored in a predetermined state. Save to the area (work area) (step # 22). The engine information read in step # 12 immediately before the replacement-required engine detection process that is currently on hold is used in the later process, so it is maintained in the work area as it is.

Next, the first trader information of the first trader corresponding to the variable k specified at the present time and the first spare engine information of the first trader are read from the database unit 11, and a predetermined storage area is temporarily stored. Save to (work area) (step # 23).

Next, based on the read first trader information and the first device information, the first trader corresponding to the variable k is within a predetermined range from the installation location of the engine type power generation device 100 in which the replacement engine is detected. Judgment as to whether or not it is an existing first trader (first first trader determination) is performed (step # 24). Here, as a criterion within a predetermined range, for example, it is within the same prefecture or an adjacent prefecture, or within a predetermined time (for example, within 2 to 4 hours) when traveling by car. Etc. are used. Here, if the first trader corresponding to the variable k exists within the above predetermined range (YES branch), the variable A (k) is set to 1 (step # 25), and if it does not exist, the variable A (k) is maintained at 0, and the process directly proceeds to the next step (step # 26).

Next, based on the read engine information and the first spare engine information, it is determined whether or not the first trader corresponding to the variable k has a spare vehicle engine that can be replaced with the replacement engine (first). 2) (1st trader determination) is performed (step # 26). Here, as a criterion for determining whether or not the engine can be replaced, the engine requiring replacement and the engine for the spare vehicle do not have to be exactly the same model, but the maximum output of the engine for the spare vehicle is normal for the engine requiring replacement. It is preferable that the maximum output at the time is within a certain range, and further, it is preferable that the fuel type is also the same. In the present embodiment, since a methane gas engine is assumed, the spare vehicle engine is also preferably a methane gas engine, but at the replacement site, for example, the gasoline engine may be modified to a methane gas engine. Here, if the first trader corresponding to the variable k has a spare vehicle engine that can be replaced with the replacement engine (YES branch), the variable B (k) is set to 1 (step #). 27) If it does not exist, the process directly proceeds to the next step (step # 28).

Next, it is determined whether or not the first supplier to be determined is the last first supplier (k = K) (step # 28). In the determination of step # 28, if it is not the last first trader (NO branch), the variable k is increased by 1 and the variables A (k) and B (k) are initialized to 0, respectively ( Step # 29), the process proceeds to the next first trader, the processes of steps # 23 to # 28 are repeated, and if it is the last first trader (YES branch), it directly goes to the next step (step # 30). Transition. The variables A (k) and B (k) in steps # 21 and # 29 may be initialized after each NO branch in steps # 24 and # 26.

Next, both the variable A (k) and the variable B (k) are 1 based on the variable A (k) and the variable B (k) showing the results of the first and second first trader determinations. Select the first vendor (step # 30). When the number of the selected first traders is 1 (branch "1"), the one first trader is determined as the first trader selected in the first trader selection process of step # 20 (step #). 31).

When the number of the selected first traders is 2 or more (branch "2 or more"), one 1st trader is selected from the 2 or more first traders as follows, and step # 20 is performed. It is determined as the first trader selected in the first trader selection process (step # 32). The method of selecting one first company from two or more first companies is not limited to a specific selection method, but as an example, the model of the spare vehicle engine is the same as that of the engine requiring replacement. Priority is given to the first trader, the first trader whose fuel type of the spare vehicle engine is the same as the replacement engine is preferentially selected, and the engine type power generation device 100 in which the replacement engine is detected is installed. At the installation location of the engine-type power generator 100, which preferentially selects the first contractor who has replaced the engine that needs to be replaced with respect to the engine-type power generator 100 in the past. It is preferable to use any one or a combination of two or more of the selection criteria such as preferentially selecting the closest first trader (selection method 1 of the first trader).

When the number of the selected first traders is 0 (branch "0"), one or two first traders in which either the variable A (k) or the variable B (k) is 1. One trader is selected as follows, and is determined as the first trader selected in the first trader selection process of step # 20 (step # 33). First, when there is one first trader in which the variable B (k) is 1, the address of the first trader is determined from the detected installation location of the engine-type power generation device 100 to determine the first trader. If the area is within a certain distance from the specified range of the standard, one of the first vendors is selected. However, if the address of the first trader is outside the surrounding area, the first trader is selected as the first trader who only provides a spare vehicle engine, and only the replacement engine is replaced. One of the first traders is selected from the first traders having the variable A (k) of 1 in the following manner. For example, the first supplier who installed the engine-type power generation device 100 in which the replacement-required engine was detected is preferentially selected. Use one of the selection criteria, such as preferentially selecting a supplier, preferentially selecting a first supplier near the installation location of the engine-type power generation device 100, or a combination of two or more (first). 1 Method of selecting a vendor 2). The method of selecting a first company that only replaces an engine that requires replacement is not limited to the above method. Further, in the present embodiment, the determination criteria for determining the first first trader is set so that one or more first traders having the variable A (k) of 1 always exist.

Next, when the number of the first traders in which the variable B (k) is 1 is 2 or more, the address is determined from the installation location of the engine-type power generation device 100 detected among the 2 or more first traders. A first trader, which is a peripheral area within a certain distance, is selected from within a predetermined range of the judgment criteria for determining the first first trader. Here, when a plurality of first traders are selected, for example, one first trader is selected by using the first trader selection method 1. If the first supplier is not selected from the surrounding area, one first supplier only provides a spare vehicle engine, for example, the first supplier whose spare vehicle engine model is the same as the replacement engine. Use one of the selection criteria, such as preferentially selecting, or preferentially select the first supplier with the same fuel type as the spare vehicle engine that requires replacement, or a combination of two or more. (Selection method 3 of the first trader) to select. Then, one first trader who only replaces the replacement-required engine is selected by using, for example, the selection method 2 of the first trader.

Next, when the number of the first traders whose variable B (k) is 1 is 0, there is no first trader who has a spare vehicle engine that can be replaced with the replacement engine, so only the replacement of the replacement engine is required. One of the first traders having the variable A (k) of 1 is selected by using, for example, the selection method 2 of the first trader. When the number of the first traders in which the variable A (k) is 1 is 1, the first trader is automatically selected. In this case, the selected first trader is required to arrange a spare vehicle engine that can be replaced with a replacement engine from a source other than the registered first trader.

As described above, through any one of steps # 31 to # 33, the first supplier to replace the engine requiring replacement is determined, and the following output processing (steps # 34 to # 36) is performed to perform the following output processing (steps # 34 to # 36) for one engine requiring replacement. 1 The supplier selection process (step # 20) is completed, and the process returns to step # 14 of the replacement-required engine detection process.

When any of steps # 31 to # 33 is completed, the engine identification code of the engine requiring replacement detected in step # 13 and the engine requiring replacement determined in any of steps # 31 to # 33 are replaced. The trader identification code of the first trader is transmitted to the first notification unit 15 (step # 34). First, the first notification unit 15 is in charge of the operation in order to notify the operation person of the system 10 that the replacement engine is detected and the first company to replace the replacement engine is selected. Output processing such as sending an e-mail to a computer terminal or the like used by a person or displaying it on a predetermined display output device is performed (step # 35). Further, the first notification unit 15 provides information necessary for the exchange-required engine and the selected first trader to perform the exchange (for example, a part or all of the engine information related to the exchange-required engine, first. A part or all of the device information, a part or all of the attribute information of the user) is subjected to an output process for transmitting an e-mail to the first computer terminal 301 or the like used by the first trader (step # 36). In step # 36, only the information (URL, etc.) for accessing the information necessary for the exchange is sent by e-mail to the effect that the replacement engine is detected and the first contractor is requested to exchange, and the information necessary for the exchange is sent. May allow the first trader to access and obtain the information source specified by the URL or the like. The first notification unit 15 may perform only the output processing of either step # 35 or step # 36. When the first notification unit 15 does not perform the output processing of step # 36, the replacement engine is detected in the output processing of step # 35, and the first supplier who replaces the replacement engine is selected. The person in charge of operation of the system 10 who has received the notification may perform the same processing as the output processing of step # 36 based on the content of the notification, for example, from the computer terminal used by himself / herself. , Telephone contact, etc. may be used together.

The operation of the replacement-required engine is normally stopped until it is replaced with a spare vehicle engine by the first contractor, and the generator 102 driven by the replacement-requiring engine is also in a state of stopping power generation. ing. Therefore, if the replacement of the replacement-required engine is delayed, the power generation suspension period becomes longer, and during that period, another vehicle engine 101 may be detected as the replacement-requiring engine by the subsequent replacement-requiring engine detection process. Therefore, since there is a possibility that two or more vehicle engines 101 stop operating at the same time, the number of vehicle engines 101 is preferably 3 or more as described above.

The vehicle engine 101, the generator 102, the inverter unit 104, the operation control unit 105, and the first state measuring instrument 106 are the same as those of the engine type power generation device 100 of the first embodiment. Omit. Further, the exhaust gas discharge unit and the auxiliary power supply unit (not shown) described in the first embodiment may be provided as a component of the engine type power generation device 200 or as a separate body. In the present embodiment as well, as in the first embodiment, the vehicle engine 101 is assumed to be a methane gas engine that can use a fuel gas containing methane gas as a main fuel. However, in the present embodiment, it is assumed that biogas containing methane gas as a main component is used as the fuel gas. The biogas contains carbon dioxide and components derived from biogas in addition to the main component methane gas.

Similar to the fuel supply unit 103 of the engine-type power generation device 100 of the first embodiment, the fuel supply unit 203 has a fuel gas tank for storing fuel gas and compression for boosting the fuel gas discharged from the fuel gas tank to a predetermined pressure. _{A CO 2} removal device 207 is provided with a machine and a pipe for delivering the fuel gas to the fuel gas inlet / outlet of each vehicle engine 101, and further selectively removes carbon dioxide contained in the fuel gas with respect to the methane gas. Be prepared. If the fuel gas in the fuel gas tank is adjusted to the predetermined pressure, the compressor is unnecessary, and if the fuel gas in the fuel gas tank is higher than the predetermined pressure, the fuel gas is used. A decompressor is provided to reduce the pressure to the predetermined pressure. Further, in the present embodiment, it is assumed that the biogas-derived components such as hydrogen sulfide and siloxane contained in the biogas are removed in advance by using an existing desulfurization device, a siloxane removal device, etc., and stored in a fuel gas tank. do.

As _{an example, the CO 2} removing device 207 is configured to include a facilitating transport membrane formed by adding, for example, a well-known carrier substance that selectively reacts with carbon dioxide into a gel membrane, and promotes fuel gas. It is supplied to the supply-side treatment chamber, and carbon dioxide is selectively permeated through the methane gas from the permeation-side treatment chamber of the accelerated transport membrane to separate it. The fuel gas from which carbon dioxide has been separated and removed is taken out from the supply-side processing chamber of the accelerated transport membrane. The CO ₂ removal device 207 is installed between the fuel gas tank and the compressor, or on the downstream side of the compressor.

The second state measuring instrument 206 is a measuring instrument that measures the second operating state data including one or more operating state values indicating the operating state _{of the CO 2 removing device 207.} The operating state value of 1 or more is, for example, at least one of the flow rate, temperature, pressure, methane gas concentration, carbon dioxide concentration, and relative humidity of the fuel gas supplied to the supply side processing chamber of the _{CO 2 removal device 207.} Pretreatment data including one and the flow rate, temperature, pressure, methane gas concentration, carbon dioxide concentration, and relative humidity of the fuel gas with reduced carbon dioxide concentration emitted from the supply side treatment chamber of the _{CO 2 removal device 207.} It is composed of post-processing data including at least one corresponding to the pre-processing data. In this case, the measuring instrument is a flow meter, a thermometer, a pressure gauge, a methane gas concentration meter, a carbon dioxide concentration meter, a relative hygrometer, or a combination of the measuring instruments. Includes measurement data of operating condition values measured by the measuring instrument. As post-treatment data, the above-mentioned treatment within the flow rate, temperature, pressure, methane gas concentration, carbon dioxide concentration, and relative humidity of the fuel gas having an increased carbon dioxide concentration discharged from the permeation side treatment chamber _{of the CO 2 removal device 207.} At least one corresponding to the previous data may be used.

Each measuring instrument continuously measures each operating state value of the pre-processing data and the post-processing data. Like the first state measuring instrument 106, the second state measuring instrument 206 further includes an arithmetic processing unit, and the measured values of each measuring instrument are totaled for each predetermined unit period (for example, one hour). Three types of statistical values, an average value, a maximum value, and a minimum value of each measured value, are calculated as second operating state data, and the second operating state data is received for each unit period described later in the system 20. It is configured to transmit to unit 22. The second operating state data is provided with an identification code that can identify the engine-type power generation device 200 and a transmission date and time.

As another form, the second state measuring instrument 206 uses the raw measured values or the average value for each shorter period (for example, 1 to 10 minutes) in place of the above three types of statistical values in the second operation. As the state data, it may be periodically (for example, every hour) transmitted to the data receiving unit 22 of the system 20. Further, as another form, the second state measuring instrument 206 includes an arithmetic processing unit, and is based on the pre-processing data and the post-processing data (for example, the above three types of statistical values) measured by each of the above-mentioned measuring instruments. , Every predetermined unit period (for example, 1 hour), _{it is determined whether the CO 2} removal device 207 is in a failure state or a quasi-failure state with a high possibility of failure, or is in a normal state, and the calculation is performed. The determination result of the processing unit may be the above-mentioned operating state value of 1 or more.

<Database registration and update>
Next, a method of registering and updating the various information and data stored in the database unit 21 and a timing thereof will be briefly described. The first device information, the first operating state data, the engine information, the first spare engine information, and the first trader information stored in the database unit 11 described in the first embodiment have already been described in the first embodiment. Since it was explained in, I will omit the duplicate explanation.

The second device information CO ₂ removal unit 207, when registering the first device information of the CO ₂ removing device 207 engine generator apparatus 200 equipped with in the manner described in the first embodiment, operations personnel , in the same manner, with respect to the CO ₂ removal unit 207, to impart a new removal device identification code, together with the power generating device identification code of engine generator apparatus 100 to be mounted, the manufacturer name of the CO ₂ removal unit 207, CO _{2 CO 2} removal method of the removing device 207 (for example, a membrane separation type using an accelerated transport membrane), specification values (in the case of a membrane separation type, specification values related to the membrane performance of the accelerated transport membrane, structure and dimensions of the accelerated transport membrane) , Specification values related to processing capacity, etc.), repair history, etc. are stored and registered in the database unit 21. If a second contractor, which will be described later, is in charge of installing the engine-type power generation device 200, the second contractor will use the second contractor to register the second device information on behalf of the operation staff. The database unit 21 may be accessed from the second computer terminal 302 via the data communication network 300.

To update the second device information, after the power generation of the engine-type power generation device 200 is started, the CO ₂ removal device 207 is in a failure state or a quasi-failure state (defective CO ₂ removal device), and the CO ₂ removal device and the spare CO 2 removal device are updated. It is necessary to replace or repair the product, and the second contractor who performed the replacement (not necessarily the same as the second contractor when the second contractor registers the second device information) is concerned. a second computer terminal 302 to use the second trader, data communication by accessing via the network 300 to the database section 21, when replacing the defective CO ₂ removal device, the defective CO ₂ remover removed by exchange This is performed by deleting the second device information and additionally registering the second device information of the _{CO 2 removal device 207 newly introduced by exchange.} Alternatively, _{without deleting the second device information of the defective CO 2} removal device removed by replacement, information other than the power generation device identification code and the engine identification code in the second device information was newly introduced by replacement. It may be replaced with the information of the _{CO 2 removing device 207.} On the other hand, when the defective CO ₂ removing device is repaired, the second device information is updated by rewriting the information related to the repair history in the second device information of the _{defective CO 2 removing device.}

The second operating state data is obtained from each of the second state measuring instruments 206 of the plurality of engine-type power generation devices 200 to be managed via the data communication network 300 every predetermined unit period (for example, one hour). When the data is transmitted to the data receiving unit 22, and the data receiving unit 22 receives the second operating state data from each of the second state measuring instruments 206, the data receiving unit 22 stores and registers the second operating state data in the database unit 21. As described above, each second operating state data is attached with a power generation device identification code capable of identifying the engine type power generation device 200 and a transmission date and time.

The second operating state data is stored for a predetermined time (for example, for 1 to 3 days, 1 to 3 weeks, or 1 to 3 months) for all of the engine-type power generation devices 200 to be managed. When new second operation state data is added, the second operation state data older than the predetermined time is deleted.

Regarding the second vendor information, when a second vendor is newly managed by the system 20, the person in charge of operating the system 20 operates the user interface attached to the hardware constituting the system 20. Then, a new trader identification code is given to the second trader, and along with the trader identification code, the attribute information (name, department in charge, address, person in charge name, contact telephone number and e-mail address) of the second trader is given. Etc.) are stored and registered in the database unit 21 as the second trader information. To update the second vendor information, as in the case of registration, when a part of the registered items included in the second vendor information is changed by the manual operation of this system 20 by the operation staff, the changed part is changed. , Overwrite the registered items and perform the update process.

In the present embodiment, the second trader information includes first preliminary CO ₂ removing device information including the number of spare CO ₂ removal device each second trader's. Therefore, the second trader information to be newly registered, the first preliminary CO ₂ removing device information about spare CO ₂ removing device to which the second trader's also registered at the same time.

For the first spare CO ₂ removal device information, each second company assigns a new spare CO ₂ removal device identification code to each of the spare CO 2 removal devices owned by each second company, and the spare CO _{2 removal device is given.} together with the second supplier vendor identification code carrying, manufacturer name of each spare CO ₂ removal unit, CO ₂ removal system CO ₂ removing device 207 (e.g., membrane separation type using a facilitated transport membrane, etc.), specification values (In the case of the membrane separation type, the specification value related to the membrane performance of the accelerated transport film, the structure and dimensions of the accelerated transport film, the specification value related to the processing capacity, etc.), the repair history, etc. The database unit 21 is accessed from the terminal 302 via the data communication network 300 and registered. The registration is preferably carried out promptly when _{a spare CO 2} eliminator is newly retained or _{available for replacement of the defective CO 2 eliminator.}

The update of the first spare CO ₂ removal device information is performed when the second company becomes non-holding due to reasons such as using _{the spare CO 2} removal device _{owned by the second company to replace the defective CO 2 removal device.} Then, in the same manner as at the time of registration, the registration of the spare defective CO ₂ removal device in the non-possessed state is deleted. Here, the second trader who performed the replacement will additionally register the second device information as the _{replaced spare defective CO 2 removing device as the CO 2} removing device 207 newly introduced by the replacement. However, for the information other than the power generation device identification code of the second device information of the _{CO 2} removal device 207, information other than the trader identification code and the spare removal device identification code of the second supplier of _{the first spare CO 2 removal device information is used.} can.

<Defective CO ₂ removal device detection process / Second supplier selection process>
Next, _{the basic operations of the CO 2} removal abnormality detection unit 23, the second supplier selection unit 24, and the second notification unit 25 of the system 20 will be described with reference to the drawings. Since the basic operations of the replacement-required engine detection unit 13, the first supplier selection unit 14, and the first notification unit 15 have already been described in the first embodiment, duplicate explanations will be omitted. FIG. 7 is a flowchart showing an example of the procedure of _{the defective CO 2 removal device detection process of the CO 2} removal abnormality detection unit 23. FIG. 8 is a flowchart showing an example of the procedure of the second trader selection process of the second trader selection unit 24.

First, the _{defective CO 2 removal device detection process by the CO 2} removal abnormality detection unit 23 will be described with reference to FIG. 7. When the defective CO ₂ removal device detection process is started, the variable m indicating the engine-type power generation device 200 is initialized to 1 (step # 41). Here, is the correspondence between the variables m (= 1 to M, M is the total number of the engine-type power generation devices 200) and the power generation device identification code of the engine-type power generation device 100 tabulated in advance and stored in a predetermined storage area? , Make sure that each variable is part of each identification code. Thereby, the engine type power generation device 100 is uniquely specified by the variable m. The variable m is used to simplify the explanation of the defective CO ₂ removing device detection process, certain engine generator apparatus 200 in failure CO ₂ removing device detection process is not limited to the method using the variable m.

Next, the second device information and the second operation state data of _{the CO 2} removal device 207 of the engine type power generation device 200 corresponding to the variable m specified at the present time are read from the database unit 21 and temporarily predetermined. Save to the storage area (work area) (step # 42).

Next, regarding the three types of statistical values of the average value, the maximum value, and the minimum value of any one of the measured values of the pre-processing data and the post-processing _{data of the CO 2} removal device 207 of the read second operating state data. The average value of the most recent unit period (for example, 1 hour) is a predetermined reference rate of change (for example, ± 20% to 30) with respect to any one or all of the average values of a plurality of unit periods prior to the average value. %) If there is a fluctuation (increase or decrease), or the range of the maximum and minimum values (= maximum value-minimum value) of the most recent unit period is the maximum of multiple unit periods before that. The case where there is an increase exceeding a predetermined reference increase rate (for example, + 20% to 30%) for any one or all of the range of the value and the minimum value, or both. It is determined that the CO _{2 removing device 207 is a defective CO 2} removing device in a failed state or a quasi-failed state (step # 43). The determination of the defective CO ₂ removing device depends on the type of measured value, for example, in the case of methane gas concentration or carbon dioxide concentration, the difference between the pre-processing data and the post-processing data, or the pre-processing data or processing of the difference. The ratio to the post-data is calculated, and the above difference or ratio of the average value of the latest unit period (for example, 1 hour) is for any one or all of the average values of the plurality of unit periods before that. When there is a fluctuation (increase or decrease) exceeding a predetermined reference rate of change (for example, ± 20% to 30%), or the range between the maximum value and the minimum value (= maximum value-minimum value) of the most recent unit period. ) The above difference or ratio sets a predetermined reference increase rate (for example, + 20% to 30%) with respect to any one or all of the range of the maximum value and the minimum value of the plurality of unit periods prior to the difference or ratio. If there is an increase exceeding, or both, the CO ₂ removing device 207 may be determined to be _{a defective CO 2} removing device in a failed state or a quasi-failed state.

The reference change rate and the reference increase rate are _{determined for each of the operating state values of the CO 2} removing device 207, but may be the same or different from each other. Further, the reference change rate and the reference rate of increase may be constant regardless of the difference in the CO ₂ removal unit 207 or may be preset for each type of CO ₂ removing device 207.

In the determination process of the defective CO ₂ removing device (step # 43), if _{it is determined that the defective CO 2} removing device is used (YES branch), after performing the second supplier selection process (step # 50) described later. , It is determined whether or not the engine-type power generation device 200 that has undergone the determination process is the last engine-type power generation device 200 (m = M) (step # 44). In the determination process of the defective CO ₂ removing device (step # 43), _{if it is not determined to be the defective CO 2} removing device (NO branch), the second supplier selection process (step # 50) is not performed. The process proceeds to the determination of step # 44.

In the determination of step # 44, if it is not the last engine-type power generation device (NO branch), the variable m is increased by 1 (step # 45), the process proceeds to the next engine-type power generation device 200, and the step When the processes of # 22 to # 44 are repeated and it is the last engine-type power generation device (YES branch), the defective CO ₂ removal device detection process is terminated.

When one defective CO ₂ removing device detection process is completed, the above unit period (for example, 1 hour) has elapsed from the start of the _{previous defective CO 2 removing device detection process, and the above unit period has already elapsed.} Then, immediately, the next defective CO ₂ removal device detection process is started.

Next, in the determination process of step # 43 of _{the defective CO 2} removal device detection process, the second supplier selection process (step # 50: FIG. 7) is performed when the device is determined to be the _{defective CO 2 removal device (YES branch).} (See) will be described with reference to FIG. When the second trader selection process starts, the variable j indicating the second trader is initialized to 1, and the variables C (j) and D (j) are initialized to 0, respectively (step # 51). Here, the correspondence between the variables j (= 1 to J, J is the total number of the second vendors) and the vendor identification code of the second vendor is tabulated in advance and stored in a predetermined storage area, or the variable j is determined. Make sure it is part of the vendor identification code. The variable C (j) and the variable D (j) are binary variables each indicating the results of two types of determination processing described later, and there are J variables each. As a result, the second trader is uniquely identified by the variable j. The variable j is for simplifying the explanation of the second trader selection process, and the specification of the second trader in the second trader selection process is not limited to the method using the variable j. Further, the method of temporarily storing the two types of determination results, which will be described later, is not limited to the method of using the variable C (j) and the variable D (j).

Next, the first device information of the engine-type power generation device 200 corresponding to the variable m currently specified in the defective CO _{2 removal device detection process currently pending is read from the database unit 21 and temporarily determined.} It is saved in the storage area (work area) of (step # 52). _{The second device information of the CO 2} removal device 207 read in step # 42 immediately before the defective CO ₂ removal device detection process currently pending is used in the subsequent process, and is therefore maintained in the work area as it is.

Next, the second trader information of the second trader corresponding to the variable j specified at the present time is read from the database unit 21 and temporarily stored in a predetermined storage area (work area) (step # 53). .. In the present embodiment, the second trader information includes the first preliminary CO ₂ removal device information.

Next, based on the read out second trader information and the first device information, the second trader corresponding to the variable j has a predetermined range from the installation location of the engine type power generation device 200 in which the _{defective CO 2 removal device is detected.} Judgment as to whether or not it is a second trader existing in (first second trader determination) is performed (step # 54). Here, as a criterion within a predetermined range, for example, it is within the same prefecture or an adjacent prefecture, or within a predetermined time (for example, within 2 to 4 hours) when traveling by car. Etc. are used. Here, if the second trader corresponding to the variable j exists within the above predetermined range (YES branch), the variable C (j) is set to 1 (step # 55), and if it does not exist, the variable C (j) is maintained at 0, and the process directly proceeds to the next step (step # 56).

Next, based on the second device information and the first spare CO ₂ removal device information, does the second trader corresponding to the variable j have _{a spare CO 2} removal device that can be replaced with the _{defective CO 2 removal device?} Whether or not to determine (determination of the second second trader) is performed (step # 56). Here, the criteria for determining whether or not the CO ₂ can be replaced are when the CO 2 removal device 207 is replaced as a set and when _{only the promotion transport film is replaced in the membrane separation type CO 2} removal device 207 using the promotion transport membrane. So, the judgment criteria are different. If you set exchanging CO ₂ removing device 207, CO ₂ removal performance of CO ₂ removal unit 207, and the dimensions conditions of the area and volume, etc. required for the installation, the defective CO ₂ remover and the spare CO ₂ removing device It is preferable that they are generally common to each other. On the other hand, when only the accelerated transport film is replaced, the membrane performance of the accelerated transport film _{is almost the same between the defective CO 2} removing device and the spare CO ₂ removing device, and the structure and dimensions of the accelerated transport film are defective CO. It is preferable that it is the same between the ₂ removal device and the spare CO _{2 removal device.} Here, the second trader corresponding to the variable j is _{a spare CO 2} removing device that can be replaced _{with a defective CO 2} removing device (in the case of a membrane-separated CO ₂ removing device using a facilitating transport membrane, the preliminary promotion is performed. If the transport membrane is also available (YES branch), the variable D (j) is set to 1 (step # 57), and if it does not exist, the process directly proceeds to the next step (step # 58).

Next, it is determined whether or not the second vendor to be determined is the last second vendor (j = J) (step # 58). In the determination of step # 58, if it is not the last second trader (NO branch), the variable j is incremented by 1 and the variables C (j) and D (j) are initialized to 0, respectively ( Step # 59), the process proceeds to the next second trader, the processing of steps # 53 to # 58 is repeated, and if it is the last second trader (YES branch), it directly goes to the next step (step # 60). Transition. The variables C (j) and D (j) in steps # 51 and # 59 may be initialized after each NO branch in steps # 54 and # 56.

Next, both the variable C (j) and the variable D (j) are 1 based on the variable C (j) and the variable D (j) showing the results of the first and second second trader determinations. Select a second vendor (step # 60). When the number of the selected second traders is 1 (branch "1"), the one second trader is determined as the second trader selected in the second trader selection process of step # 50 (step #). 61).

When the number of the selected second traders is 2 or more (branch "2 or more"), one second trader is selected from the 2 or more second traders according to the following procedure, and step # 50 is performed. It is determined as the second supplier selected in the second supplier selection process (step # 62). The method of selecting one second company from two or more second companies is not limited to a specific selection method, but as an example, the CO _{2 removal method of the spare CO 2} removal device is defective. the same second trader and CO ₂ removal unit preferentially selected, CO ₂ removal performance spare CO ₂ removing device the same second trader preferentially selected to normal when the defective CO ₂ removal device, the pre dimension conditions of the area and volume, etc. required for the installation of the CO ₂ removal unit selects the substantially the same second trader defective CO ₂ removal unit preferentially, CO ₂ removing device 207 is a membrane separation type using a facilitated transport membrane structure and dimensions of some cases, the membrane performance of the facilitated transport membrane spare CO ₂ removing device selects substantially the same second trader defective CO ₂ removal unit preferentially, facilitated transport membrane spare CO ₂ removing device Preferentially selects the same second supplier as the defective CO ₂ removal device, and preferentially selects the second supplier who installed the engine-type power generation device 200 in which the _{defective CO 2 removal device is detected, the same as in the past.} Priority is given to the second supplier who has replaced the defective CO ₂ removal device for the engine-type power generator 200, and the second supplier near the installation location of the engine-type power generator 200 is preferentially selected. It is preferable to use any one of the selection criteria or a combination of two or more of the above selection criteria (selection method 1 of a second supplier).

When the number of the selected second traders is 0 (branch "0"), one or two second traders from among the second traders in which either the variable C (j) or the variable D (j) is 1. The two vendors are selected in the following manner and determined as the second vendor selected in the second vendor selection process in step # 50 (step # 63). First, when there is one second trader in which the variable D (j) is 1, the address of the second trader is determined from the detected installation location of the engine-type power generation device 200 to determine the first second trader. If the area is within a certain distance from the specified range of the standard, one of the second vendors is selected. However, if the address of the second trader is outside the peripheral area, the second trader is selected as the second trader who only provides a _{spare CO 2 remover, and the defective CO 2} remover is replaced. Alternatively, one second contractor who only repairs is selected from the second contractors whose variable C (j) is 1 in the following manner. For example, preferentially select a second supplier who has installed the engine-type power generation device 200 in which the _{defective CO 2} removal device is detected, or replace the _{defective CO 2 removal device with respect to the engine-type power generation device 200 in the past.} One or more of the selection criteria, such as preferentially selecting the second contractor who performed the repair, preferentially selecting the second contractor near the installation location of the engine-type power generator 200, etc. Used in combination (selection method 2 of a second supplier). The method of selecting a second company that only replaces or repairs the defective CO _{2 removing device is not limited to the above method.} Further, in the present embodiment, the judgment criteria for determining the first second trader is set so that the second trader having the variable C (j) of 1 always exists at least one.

Next, when the number of the second traders in which the variable D (j) is 1 is 2 or more, the address is detected from the installation location of the engine-type power generation device 200 among the 2 or more second traders. A second trader, which is a peripheral area within a certain distance, is selected from within a predetermined range of the judgment criteria for determining the first second trader. Here, when a plurality of second traders are selected, for example, one second trader is selected by using the above-mentioned second trader selection method 1. Further, when the second trader is not selected from the surrounding area _{, as a second trader who only provides a spare CO 2} removal device, for example, the judgment criteria of the second second trader determination is more or better. Priority is given to one second supplier who is satisfied. Then, one second trader who only replaces or repairs the defective CO ₂ removing device is selected, for example, by using the selection method 2 of the first trader.

Next, when the number of the second traders in which the variable D (j) is 1 is 0, there is no second trader who has _{a spare CO 2} remover that can be replaced with the _{defective CO 2 remover, so that the bad CO 2 is defective.} A second trader who only replaces or repairs the removal device is selected from the second traders having the variable C (j) of 1, for example, by using the selection method 2 of the second trader. When the number of the first traders in which the variable C (j) is 1 is 1, the second trader is automatically selected. In this case, if it is necessary to replace the defective CO ₂ removing device, the second trader selected from other than the second trader being registered, replaceable spare CO ₂ remover defective CO ₂ removing device Is required to arrange.

As described above, through any one of steps # 61 to # 63, a _{second supplier who replaces or repairs the defective CO 2} removing device is determined, and the following output processing (steps # 64 to # 66) is performed to perform one defect. The second supplier selection process (step # 50) for the CO ₂ removal device is completed, and the process returns to step # 44 of _{the defective CO 2 removal device detection process.}

Step # either 61 to # 63 is completed, the step # and removing device identification code of the detected defective CO ₂ removing device 43, step # 61 to # the defective CO ₂ removal as determined by any one of 63 The trader identification code of the second trader who replaces or repairs the device is transmitted to the second notification unit 25 (step # 64). The second notification unit 25 first notifies the operation staff of the system 20 that _{the defective CO 2} removing device has been detected _{and a second company for replacing or repairing the defective CO 2 removing device has been selected.} Therefore, output processing such as sending an e-mail to a computer terminal or the like used by the operation person, displaying the e-mail on a predetermined display output device, or the like is performed (step # 65). Further, the second notification unit 25 _{provides information necessary for the defective CO 2} removing device and the selected second contractor to perform the replacement or repair (for example, information on the second device related to the _{defective CO 2 removing device).} Part or all of, part or all of the first device information, part or all of the attribute information of the user), output processing to send an e-mail to the second computer terminal 302 or the like used by the second company. Do (step # 66). In step # 66, only the information (URL, etc.) for accessing the information necessary for the replacement or repair is sent by e-mail to the effect that _{the defective CO 2 removal device is detected and the second contractor is requested to replace or repair the device.} , Information necessary for replacement or repair may be obtained by the second trader by accessing the information source specified by the URL or the like. The second notification unit 25 may perform only the output processing of either step # 65 or step # 66. If the second notification unit 25 does not perform the output processing of step # 66, a defective CO ₂ removing device is detected in the output processing of step # 65, and a second supplier who replaces or repairs the _{defective CO 2 removing device.} The person in charge of operation of the system 20 who has received the notification that is selected is to perform the same processing as the output processing of step # 66 from the computer terminal used by himself / herself, based on the content of the notification. Alternatively, telephone contact or the like may be used together.

[Third Embodiment]
Next, a third embodiment of this system will be described with reference to the drawings. The engine-type power generation device to be managed by the system in the third embodiment is any one of the engine-type power generation devices 100 and 200 described in the first and second embodiments.

<Outline configuration of this system>
Next, the schematic configuration of the system 30 in the third embodiment will be described with reference to the drawings. FIG. 9 is a block diagram schematically showing a schematic configuration example of the system 30. As shown in FIG. 9, the system 30 is configured by further including an operation suspension control unit 36 in addition to the configurations of the systems 10 and 20 of the first or second embodiment. As an example, FIG. 9 shows a configuration example in which the operation suspension control unit 36 is added to the system 10 of the first embodiment for the sake of simplicity. Therefore, in the following description, the engine-type power generation device 100 to be managed by the system 30 is assumed to be the engine-type power generation device 100 described in the first embodiment. In the present embodiment, the operation control unit 105 of the engine-type power generation device 100 communicates with the operation suspension control unit 36 via a data communication network 300 such as the Internet in the engine selection process by the operation suspension control unit 36 described later. In order to transmit and receive data, both the operation control unit 105 and the operation suspension control unit 36 are provided with a well-known communication interface for communication via the data communication network 300. The communication interface included in the operation suspension control unit 36 may be shared with the data receiving unit 12 or the first notification unit 15. Further, the communication interface provided in the operation control unit 105 may be shared with the first state measuring instrument 106. The basic configuration of the engine-type power generation device 100, the database unit 11, the data receiving unit 12, the replacement engine detection unit 13, the first supplier selection unit 14, and the first notification unit 15 are in the first embodiment. Since it is the same as the one already explained, duplicate explanations are omitted.

The operation suspension control unit 36 has, for each of the plurality of engine-type power generation devices 100 to be managed, a plurality of vehicles being operated based on the engine information and the first operation state data to be described later stored in the database unit 11. A pause-requiring engine for temporarily suspending operation is selected from a part of the engine 101 for vehicles, and a restart-required engine for restarting operation is selected from a part of a plurality of vehicle engines 101 that are suspended. The engine selection process is configured to be executed sequentially. The operation suspension control unit 36 is similar to the control devices of the data reception unit 12, the replacement engine detection unit 13, the first supplier selection unit 14, the first notification unit 15, and the database unit 11, for example, the CPU, the MPU, and the like. The arithmetic processing unit is configured to include a memory device such as a semiconductor memory, and the arithmetic processing unit executes the predetermined program to perform the engine selection process. The operation suspension control unit 36 can be configured by a general-purpose computer such as a personal computer having a function of connecting to the Internet, together with a replacement engine detection unit 13, a first supplier selection unit 14, and a first notification unit 15.

<Database registration and update>
In the present embodiment, for all of the plurality of engine-type power generation devices 100 to be managed, the engine information of each vehicle engine 101 stored in the database unit 11 is transferred to a new engine or a vehicle manufactured to be mounted on the vehicle. If the vehicle engine 101 is a used engine, it further has information on the cumulative mileage during the period in which the vehicle was installed, and stores it in the database unit 11. The first operating state data of each vehicle engine 101 is the information that can calculate the cumulative operating time or the cumulative operating time since it is mounted on the engine-type power generation device 100 of the vehicle engine 101, and whether the vehicle is in operation or stopped. It also has information that indicates the distinction between vehicles or can determine the distinction, and the latest operation start date and time.

In addition, information indicating the distinction between a new engine and a used engine and information on the cumulative mileage in the case of a used engine, which are items newly added to the above engine information, have been described in the first embodiment. When the engine information is registered, it is registered by the person in charge of operating the system 30 or the first company in charge of installing the engine-type power generation device 100 in the same manner as other items. Further, when the replacement-required engine is replaced with the spare vehicle engine 101, the first trader who made the replacement updates the item in the same manner as the other items of the engine information.

In the present embodiment, the first state measuring instrument of the engine-type power generation device 100 has a timing function, and a plurality of vehicle engines 101 mounted on each engine-type power generation device 100 are operated by the operation control unit 105. When the start and stop are controlled, the start date and time and the stop date and time of the operation are measured respectively and included in the first operation state data as the operation state value of each vehicle engine 101.

By recording the start date and time and the stop date and time of operation after being mounted on the engine-type power generator 100 of the vehicle engine 101, the cumulative operating time since being mounted on the engine-type power generator 100 of the vehicle engine 101. Can be calculated. Further, since it is possible to know which of the start date and time and the stop date and time is the closest from the start date and time and the stop date and time of the operation, it is possible to distinguish whether each vehicle engine 101 is in operation or stopped. Therefore, in the present embodiment, the start date and time and the stop date and time of the operation are information that can calculate the cumulative operation time after being mounted on the engine type power generation device 100 of the vehicle engine 101, and each vehicle engine 101 is in operation. It is used as information that can determine whether the vehicle is stopped or stopped, and as the latest operation start date and time.

As described in the first embodiment, the first operating state data includes the number of a plurality of vehicle engines 101 mounted on the first state measuring instruments 106 of the plurality of engine-type power generation devices 100 to be managed. Minutes are transmitted to the data receiving unit 12 via the data communication network 300 every predetermined unit period (for example, one hour). Therefore, it is sufficient to transmit only the start date and time and the stop date and time of the operation that occurred within the latest unit period to the data receiving unit 12.

In the present embodiment, the cumulative operation time from when the data receiving unit 12 that has received the start date and time and the stop date and time of the operation is mounted on the engine-type power generation device 100 of the vehicle engine 101 to the latest operation stop date and time (hereinafter,, It is assumed that the case of calculating (referred to as "first cumulative operation time") is performed. If the operation has never been stopped since it was mounted on the engine-type power generation device 100, the first cumulative operation time is 0 hours.

When the data receiving unit 12 receives the start date and time of the first operation of each vehicle engine 101 after being mounted on the engine-type power generation device 100, the database unit 11 sets the first start date and time as the most recently received start date and time. In addition to storing and registering in, the flag indicating the operating state of the vehicle engine 101 is set to 1 (indicating that the vehicle is in operation). When the data receiving unit 12 receives the stop date and time of the first operation after being mounted on the engine-type power generation device 100 at the same or later reception timing, the database unit 12 sets the first stop date and time as the most recently received stop date and time. Even if it is stored and registered in 11, the first cumulative operation time of the first operation period is calculated from the latest received start date and time and stop date and time, stored in the database unit 11 and registered, and the operation of the vehicle engine 101 is performed. Set the status flag to 0 (indicates that it is stopped). The flag is stored in a predetermined storage area (work area) used in the engine selection process described later for each engine type power generation device 100 and each vehicle engine 101.

Every time a new operation start date and time is received at a subsequent reception timing, the data reception unit 12 overwrites and registers the previous start date and time as the most recently received start date and time, and operates the vehicle engine 101. Set the status flag to 1 (indicating that the vehicle is in operation). Similarly, every time a new operation stop date and time is received at the subsequent reception timing, the previous stop date and time is overwritten and registered as the latest received stop date and time, and the latest received start date and time is displayed. The cumulative operating time of the latest operating period up to the received stop date and time (hereinafter referred to as the "second cumulative operating time") is calculated, and the second cumulative operating period of the latest operating period is added to the already registered first cumulative operating time. The driving time is added, and the new first cumulative driving time is stored and registered in the database unit 11, and the flag indicating the operating state of the vehicle engine 101 is set to 0 (indicating that the vehicle is stopped).

<Engine selection process>
Next, the engine selection process by the operation suspension control unit 36 of the system 30 will be described with reference to FIG. FIG. 10 is a flowchart showing an example of the procedure of the engine selection process of the operation suspension control unit 36.

When the engine selection process starts, the variables m and n indicating the engine-type power generation device 100 and the vehicle engine 101 are initialized to 1 respectively (step # 71). Here, the correspondence between the variable m (= 1 to M, M is the total number of the engine type power generation device 100) and the power generation device identification code of the engine type power generation device 100, and the variable n in the mth engine type power generation device 100 ( = 1 to N (m), N (m) is the total number of vehicle engines 101 used in the m-th engine-type power generation device 100) and the correspondence between the engine identification code of the vehicle engine 101 are tabulated in advance. Make sure it is stored in a given storage area or that each variable is part of each identification code. As a result, the engine type power generation device 100 and the vehicle engine 101 are uniquely identified by the variables m and n. The variables m and n are for simplifying the explanation of the engine selection process, and the specification of the engine type power generation device 100 and the vehicle engine 101 in the engine selection process is not limited to the method using the variables m and n. ..

Next, among the engine information of the engine-type power generator 100 and the vehicle engine 101 corresponding to the variables m and n specified at the present time, the information indicating the distinction between the new engine and the used engine, and the case of the used engine. The information regarding the cumulative mileage of the above, the first cumulative operation time set and registered by the data receiving unit 12 in the first operation state data, the latest operation start date and time, and the operation stop date and time are read from the database unit 11. Further, when the vehicle engine 101 corresponding to the variables m and n is a used engine, the information on the cumulative mileage indicates or the cumulative mileage calculated from the information is calculated by using a predetermined conversion formula. Alternatively, referring to a predetermined conversion table, it is converted into a cumulative driving time, added to the read first cumulative driving time, and further, the above-mentioned flag F (m,) of the vehicle engine 101 corresponding to the variables m and n. When n) is 1, the third cumulative operation time, which is the cumulative operation time from the latest operation start date and time and the latest operation start date and time to the present time, is calculated and added to the first cumulative operation time. The first cumulative operation time T1 (m, n) and the third cumulative operation time T3 (m, n) after the addition are temporarily stored in a predetermined storage area (work area) (step # 72).

Next, it is determined whether or not the vehicle engine 101 corresponding to the variable n is the last vehicle engine (n = N (m)) in the engine-type power generation device 100 corresponding to the variable m (step # 73). ). If it is not the last vehicle engine (NO branch), the variable n is incremented by 1 (step # 74) to move to the next vehicle engine 101 of the same engine-type power generator 100, and steps # 72 to # When the process of 73 is repeated and the engine is the last vehicle (YES branch), the process proceeds to the next stop-required engine selection process (step # 75).

In step # 75, the flag F (m, n) is formed by formulating or tabulating the relationship between the first cumulative operation time T1 and the lower limit value T3L and the upper limit value T3H of the third cumulative operation time T3. From the currently operating vehicle engine 101 of 1, the third cumulative operating time T3 (m, n) is selected from the lower limit value T3L or more. Further, a vehicle currently inactive with a flag F (m, n) of 0 is used by formulating or tabulating the relationship between the first cumulative operating time T1 and the lower limit value T4L of the operating suspension period T4. The number of engines whose operation suspension period T4 (m, n) is equal to or greater than the lower limit value T4L is defined as the number of engines that can be suspended, and the total number of vehicle engines 101 that are currently suspended is the number of engines that are currently suspended. And. The operation suspension period T4 (m, n) is calculated as the time from the latest operation stop date and time to the current date and time. P ≦ Q.

If the vehicle engine 101 having a third cumulative operating time T3 (m, n) of the lower limit value T3L or more is not 0 with the number of engines that can be suspended P or less, the selected vehicle engine 101 is regarded as a suspension engine. select. Further, when the vehicle engine 101 having a third cumulative operating time T3 (m, n) of the lower limit value T3L or more exceeds the number of engines P that can be stopped, the third cumulative operating time T3 (m, n) is the upper limit value. If there is an engine that is close to T3H and exceeds the upper limit value T3H, P units are selected from those that have a large difference from the upper limit value T3H, and the engine is selected as a suspension-required engine. If the third cumulative operating time T3 (m, n) is a vehicle engine 101 having a lower limit value T3L or more and is not selected for the P unit and exceeds the upper limit value T3H, the upper limit value is reached. The (QP) units are selected in descending order of the difference from the T3H, and the total Q units are selected as the suspension-required engines. Here, let R be the number of vehicle engines 101 selected as the suspension-requiring engine. When the vehicle engine 101 having a third cumulative operating time T3 (m, n) of the lower limit value T3L or more is 0, the engine requiring suspension is not selected and R = 0.

The relationship between the first cumulative operation time T1 and the lower limit value T3L and the upper limit value T3H of the third cumulative operation time T3 is that as the first cumulative operation time T1 increases, both the lower limit value T3L and the upper limit value T3H become smaller. Is set to. As a result, the vehicle engine 101 having a larger first cumulative operating time T1 (m, n) is more likely to be selected as a stop-requiring engine, and conversely, the vehicle engine 101 having a smaller first cumulative operating time T1 (m, n). Since it is more difficult to select the engine as a suspension-required engine, the leveling of the first cumulative operating time T1 (m, n) is progressing among a plurality of vehicle engines 101 mounted on the same engine-type power generation device 100. Therefore, the life of the plurality of vehicle engines 101 can be extended as a whole.

Next, a restart-requiring engine selection process is performed to select the R-vehicle engine 101 as the restart-requiring engine from the Q-vehicle engine 101 currently inactive with the flag F (m, n) set to 0. (Step # 76). When R = Q, all of the Q-unit vehicle engines 101 that are currently inactive are selected as restart-required engines. When 0 <R <Q, the R units are selected in order from the Q units of vehicle engines 101 that are currently inactive, in order from the one in which the operation suspension period T4 exceeds the lower limit value T4L for a long time. When R> P, the vehicle engine 101 in which the operation suspension period T4 does not exceed the lower limit value T4L is also in order from, for example, the one having the longest operation suspension period T4 or the one whose operation suspension period T4 is closer to the lower limit value T4L. Select and select the total R unit to make it a restart required engine. When R = 0, the restart-required engine is not selected.

In the present embodiment, the relationship between the first cumulative operation time T1 and the lower limit value T4L of the operation suspension period T4 is set so that the lower limit value T4L increases as the first cumulative operation time T1 increases. However, the lower limit value T4L may be set to a constant value regardless of the first cumulative operation time T1. However, if the first cumulative operation time T1 is the same, T4L <T3L <T3H.

Next, the operation suspension control unit 36 sets the engine identification code of the suspension-requiring engine selected in step # 75 and the engine identification code of the restart-requiring engine selected in step # 76 to the engine-type power generation device 100 corresponding to the variable m. (Step # 77), the data is transmitted to the operation control unit 105 of the above via a data communication network 300 such as the Internet.

When the operation control unit 105 of the engine-type power generation device 100 corresponding to the variable m receives the engine identification code of the stop-requiring engine and the restart-requiring engine, the operation control unit 105 of the engine-type power generation device 100 refers to the suspension-requiring engine and the restart-requiring engine specified by the engine identification code. , The control for stopping the operation and the control for restarting the operation are performed, respectively (step # 80).

Following step # 77, the operation suspension control unit 36 determines whether or not the engine-type power generation device 100 corresponding to the variable m is the last engine-type power generation device (m = M) (step # 78). In the determination of step # 78, if it is not the last engine-type power generator (NO branch), the variable m is increased by 1 and the variable n is initialized to 1 (step # 79), and the next engine-type power generation is performed. The process shifts to the first vehicle engine 101 of the device 100, the processes of steps # 72 to # 78 are repeated, and if it is the last engine-type power generation device (YES branch), the engine selection process ends.

[Another Embodiment]
Next, a modified example (another embodiment) of the first to third embodiments will be described.

<1> In the first embodiment, the configuration example in which the system 10 includes the first supplier selection unit 14 and the first notification unit 15 has been described, but the configuration without the first notification unit 15 or the first The configuration may not include the vendor selection unit 14 and the first notification unit 15. If the first notification unit 15 is not provided, the output processing of steps # 34 to # 36 of the first supplier selection process described above is not performed, so that the first supplier selection unit 14 replaces the first notification unit 15. , The operation person in charge of the system 10 who received the notification that the output processing of step # 35 was performed, the replacement engine was detected, and the first supplier to replace the replacement engine was selected, sent the notification. Based on the content, a process similar to the output process of step # 36 may be performed from, for example, a computer terminal used by the user.

Further, when the first supplier selection unit 14 and the first notification unit 15 are not provided, the first supplier selection process (step # 20) is not executed, so that the replacement engine detection unit 13 determines that the replacement engine is required. In the case of (YES branch in step # 13), instead of the first supplier selection process (step # 20), the engine requiring replacement is detected, and the engine identification code of the engine requiring replacement is assigned to the operation manager. The person in charge of operation of the system 10 who receives the notification performs output processing such as sending an e-mail to a computer terminal or the like used by the person or displaying it on a predetermined display output device, based on the content of the notification. , The first trader who replaces the replacement-required engine with the spare vehicle engine may be selected by using a list or the like that summarizes the information of the first trader prepared separately.

<2> In the second embodiment described above, a configuration example in which the system 20 includes a first supplier selection unit 14, a first notification unit 15, a second supplier selection unit 24, and a second notification unit 25 has been described. , A configuration without a first notification unit 15, a configuration without a first vendor selection unit 14 and a first notification unit 15, a configuration without a second notification unit 25, or a configuration without a second vendor selection unit 24 and a second notification. The configuration may not include the portion 25. Since the configuration without the first notification unit 15 and the configuration without the first vendor selection unit 14 and the first notification unit 15 have been described in <1> above, duplicate explanations will be omitted. If the second notification unit 25 is not provided, the output processing of steps # 64 to # 66 of the second supplier selection process described above is not performed, so that the second supplier selection unit 24 replaces the first notification unit 25. , The operation person in charge of the system 20 who received the notification that the output processing of step # 65 was performed, the defective CO ₂ removing device was detected, and _{the second contractor for replacing or repairing the defective CO 2 removing device was selected.} A person may perform the same processing as the output processing of step # 66 based on the content of the notification, for example, from a computer terminal used by the person.

Further, when the second supplier selection unit 24 and the second notification unit 25 are not provided, the second supplier selection process (step # 50) is not performed, so that the CO ₂ removal abnormality detection unit 23 is a defective CO ₂ removal device. If it is determined that (YES branching of the step # 43), the first of the second trader selection process in place (step # 50), and that the defective CO ₂ removing device is detected, the defective CO ₂ removing device 2 The person in charge of operation of the system 20 who has received the notification after performing output processing such as sending an e-mail to the computer terminal or the like used by the person in charge of operation of the device or displaying the device identification code on a predetermined display output device. but based on the contents of the notification, by using a separately prepared list, such as a summary of the second trader information, the second trader to replace or repair defective CO ₂ removal unit with a spare CO ₂ removing device May be selected.

<3> A modified example of the first supplier selection process described in the first embodiment will be described. In this modification, the database unit 11 stores the second spare engine information for each user in addition to the first spare engine information. The second spare engine information is information including the number of spare vehicle engines owned by one or more users and their specifications or models. If the plurality of vehicle engines 101 mounted on the engine-type power generation device 100 used by the user can be replaced with any of the spare vehicle engines owned by the user, the specifications of the spare vehicle engine. Or information about the model is not always necessary.

For the second spare engine information, when the first device information is registered, the person in charge of operation assigns a new spare engine identification code, and together with the user identification code of the user who owns the spare vehicle engine, each spare vehicle Engine manufacturer name, used / new distinction, fuel type, model, engine type distinction, displacement, maximum output, standard output during steady operation, standard rotation speed, standard air fuel ratio, standard fuel supply amount, standard The attributes, characteristics, and specification values of the vehicle engine 101 such as the cooling water temperature are registered by operating the user interface attached to the hardware constituting the system 10. When the first contractor is in charge of the installation of the engine-type power generation device 100, the first contractor uses the registration of the second spare engine information on behalf of the operation staff. The database unit 11 may be accessed from the first computer terminal 301 via the data communication network 300.

The update of the second spare engine information is performed at the time of registration when the first trader becomes non-owned due to reasons such as using the spare vehicle engine owned by the user for replacement with a replacement engine. This is done by deleting the registration of the spare vehicle engine in the non-owned state in the same manner as above. Here, the first trader who performed the replacement will additionally register the engine information of the replaced spare vehicle engine as the vehicle engine 101 newly introduced by the replacement, but for the vehicle. As the information other than the power generation device identification code and the engine identification code of the engine information of the engine 101, information other than the user identification code and the spare engine identification code of the second spare engine information can be used.

By the way, the replacement-required engine replaced with the spare vehicle engine may be owned by the same user as a spare vehicle engine after being repaired without being discarded as it is. In that case, the first contractor who performed the repair registers the repaired engine requiring replacement as a spare vehicle engine, and the registration of the second spare engine information is performed by the first contractor used by the first contractor. The database unit 11 may be accessed from the computer terminal 301 via the data communication network 300.

The first supplier selection process (step # 20: steps # 21 to # 36) described in the first embodiment is modified as follows as an example. Prior to step # 21 of the first supplier selection process, the second spare engine information of the user of the engine-type power generation device 100 corresponding to the variable m currently specified is read from the database unit 11 and temporarily. Save in a predetermined storage area (work area). Here, from the second spare engine information, if the user has a spare vehicle engine that can be replaced with the replacement engine, the variable B (k) is initialized in steps # 21 and # 29. In step # 23, the first spare engine information is not read, the processes of steps # 26 and # 27 are not performed, the process proceeds to step # 28, and in step # 30, the variable A (k) is 1. Select a first vendor.

When the number of the selected first traders is 1 (branch "1"), the one first trader is determined as the first trader selected in the first trader selection process of step # 20 (step #). 31). When the number of the selected first traders is 2 or more (branch "2 or more"), one 1st trader is selected from the 2 or more first traders as follows, and step # 20 is performed. It is determined as the first trader selected in the first trader selection process (step # 32). The method of selecting one first company from two or more first companies is not limited to a specific selection method, but as an example, of the engine-type power generation device 100 in which a replacement engine is detected. Of the engine-type power generator 100, which preferentially selects the first contractor who installed the engine, and preferentially selects the first contractor who has replaced the engine that needs to be replaced with respect to the engine-type power generator 100 in the past. One of the selection criteria, such as preferentially selecting the first supplier closest to the installation location, or a combination of two or more is used (first supplier selection method 2). When the number of the selected first traders is 0 (branch "0"), one first trader from the first traders whose variable A (k) is 0 is selected as the first trader selection method 2. The selection is made in the same manner, and the first supplier selected in the first supplier selection process in step # 20 is determined (step # 33).

Due to the above changes, if the user has a spare vehicle engine that can be replaced with a replacement engine, or if there is no first company that has a spare vehicle engine that can be replaced with a replacement engine. Even so, the replacement-required engine can be replaced with a spare vehicle engine.

<4> A modified example of the second supplier selection process described in the second embodiment will be described. In this modification, the database unit 21, in addition to the first preliminary CO ₂ removing device, storing the second preliminary CO ₂ removing device by the user. The second spare CO ₂ removing device is information including the number of _{spare CO 2} removing devices owned by one or more users. It is assumed that the _{CO 2} removal device 207 used in the engine-type power generation device 200 used by the _{user can be naturally replaced with a spare CO 2} removal device owned by the user.

At the time of registration of the first device information, the operation person assigns a new spare engine identification code to the second spare CO ₂ removal device information, and together with the user identification code of the user who owns the spare vehicle engine, each Manufacturer name of spare CO _{2 removal device, CO 2 removal method of CO 2} removal device 207 (for example, membrane separation method using accelerated transport membrane, etc.), specification value (in the case of membrane separation type, membrane of accelerated transport membrane) The specification values related to performance, the structure and dimensions of the accelerated transport membrane, the specification values related to processing capacity, etc.), repair history, etc. are registered by operating the user interface attached to the hardware constituting this system 20. If the second contractor is in charge of installing the engine-type power generation device 200, the second contractor will _{register the above-mentioned second spare CO 2} removal device information on behalf of the operation staff. The database unit 21 may be accessed from the second computer terminal 302 used by the user via the data communication network 300.

The update of the information on the second spare CO ₂ remover is not held because the second trader used the spare CO ₂ remover owned by the user to replace the defective CO _{2 remover.} At that point, the registration of the spare CO ₂ removal device in the non-possessed state is deleted in the same manner as at the time of registration.

The second supplier selection process (step # 50: steps # 51 to # 66) described in the second embodiment is modified as follows as an example. _{Prior to step # 51 of the second supplier selection process, the second spare CO 2} removal device information of the user of the engine-type power generation device 200 corresponding to the variable m specified at the present time is read from the database unit 21. Temporarily save in a predetermined storage area (work area). Here, from the information on the second spare CO ₂ removing device, if the user has _{a spare CO 2} removing device that can be replaced with the _{defective CO 2} removing device, the variable D is set in steps # 51 and # 59. When the second trader information is read in step # 53 without the initialization of (j), it is not always necessary to read _{the first preliminary CO 2 removal device information.} Further, the process of steps # 56 and # 57 is not performed, the process proceeds to step # 58, and in step # 60, a second trader whose variable C (j) is 1 is selected.

When the number of the selected second traders is 1 (branch "1"), the one second trader is determined as the second trader selected in the second trader selection process of step # 50 (step #). 61). When the number of the selected second traders is 2 or more (branch "2 or more"), one second trader is selected from the 2 or more second traders according to the following procedure, and step # 50 is performed. It is determined as the second supplier selected in the second supplier selection process (step # 62). The method of selecting one second company from two or more second companies is not limited to a specific selection method, but as an example, an engine-type power generator in which a _{defective CO 2 removal device is detected.} Priority is given to the second contractor who installed the 200, and the second contractor who has replaced or repaired the _{defective CO 2 removal device for the engine type power generator 200 in the past is preferentially selected.} One of the selection criteria, such as preferentially selecting a second supplier close to the installation location of the engine-type power generator 200, or a combination of two or more is used (second supplier selection method 2). When the number of the selected second traders is 0 (branch "0"), one second trader from the second traders whose variable C (j) is 0 is selected as the second trader selection method 2. It is selected in the same manner and determined as the second supplier selected in the second supplier selection process of step # 50 (step # 63).

By the above change, if the user owns CO ₂ remover interchangeable spare defective CO ₂ removal device owns CO ₂ remover interchangeable spare defective CO ₂ removing device Even if there is no second supplier, the defective CO ₂ removing device can be replaced with a _{spare CO 2 removing device.}

<5> In the first embodiment, the first state measuring instrument 106 includes an arithmetic processing unit, and is a predetermined unit based on measurement data (for example, the above three types of statistical values) measured by each measuring instrument. Every period (for example, 1 hour), it is determined whether the vehicle engine 101 is in a failed state, a quasi-failed state, or a normal state, and the determination result of the arithmetic processing unit is used as the above-mentioned operation of 1 or more. When transmitting as a state value to the data receiving unit 12, the determination process by the first state measuring instrument 106 is a step of the replacement engine detection process by the replacement engine detection unit 13 described in the first embodiment. The determination process is the same as that in # 13, and the determination process by the replacement engine detection unit 13 simply uses the determination result of the first state measuring instrument 106 as it is.

<6> In the second embodiment, the second state measuring instrument 206 includes an arithmetic processing unit, and is based on pre-processing data and post-processing data (for example, the above three types of statistical values) measured by each measuring instrument. Then, every predetermined unit period (for example, 1 hour), _{it is determined whether the CO 2} removal device 207 is in a failed state, a quasi-failed state, or a normal state, and the determination result of the arithmetic processing unit is determined. When transmitting the operating state value of 1 or more to the data receiving unit 22, the determination process by the second state measuring instrument 206 is performed by the CO ₂ removal abnormality detecting unit 23 described in the second embodiment. The determination process is the same as the determination process in step # 43 of the defective CO _{2 removal device detection process, and the determination process by the CO 2} removal abnormality detection unit 23 simply uses the determination result of the second state measuring instrument 206 as it is. ..

<7> In the second embodiment, the replacement engine detection process by the replacement engine detection unit 13 and the _{defective CO 2 removal device detection process by the CO 2} removal abnormality detection unit 23 may be performed in parallel. Further, the replacement required engine detection process and the defective CO ₂ removal device detection process may be alternately performed. As an example, when both processes are performed in parallel, steps # 42 to # 43 and # 50 shown in FIG. 7 are inserted in parallel with steps # 12 to # 15 and # 20 shown in FIG. 3, and FIG. 3 Steps # 11, # 16, # 17 shown in FIG. 7 and steps # 41, # 46, # 47 shown in FIG. 7 may be shared. Further, as an example, when the two processes are alternately performed, steps # 42 to # 43 and # 50 shown in FIG. 7 may be inserted between steps # 14 and # 16 shown in FIG.

Here, when the replacement-required engine detection unit 13 detects the replacement-required engine and the CO ₂ removal abnormality detection unit 23 detects the defective CO ₂ removal device for the same engine-type power generation device 200, the replacement-required engine is detected. The unit 13 may determine whether the detected failure state or quasi-failure state of the engine requiring replacement is caused by the failure state or quasi-failure state of the defective CO ₂ removing device. It should be noted that the causal relationship between the failure state or quasi-failure state of the engine requiring replacement and the failure state or quasi-failure state of the defective CO _{2 removal device is organized and tabulated in advance based on past cases.} , In the above determination, the registered contents of the table shall be referred to. Further, when a plurality of vehicle engines 101 mounted on the engine-type power generation device 200 are all detected as replacement-required engines, and at the same time, the CO ₂ removal device 207 is also _{detected as a defective CO 2} removal device, it is detected. It is judged that the failure state or quasi-failure state of the engine requiring replacement is likely to be caused by _{the failure state or quasi-failure state of the defective CO 2 removing device.}

Here, when the detected failure state or quasi-failure state of the engine requiring replacement is caused by the failure state or quasi-failure state of the defective CO ₂ removal device, the output process of the second supplier selection process (step # 50) is performed. In (step # 66), it is preferable that the second notification unit 25 adds information to the effect that the cause is the information necessary for replacing or repairing _{the defective CO 2 removing device.}

<8> In the second embodiment, the first contractor who replaces the engine requiring replacement and the second contractor who replaces or repairs _{the defective CO 2 removal device are treated separately.} The second trader may be included, and conversely, the first trader may be included in the second trader.

Furthermore, is it possible to treat the first trader and the second trader as the same trader, integrate the first trader information and the second trader information into one trader information, and exchange the engine requiring replacement in the trader information? Information on whether or not the defective CO ₂ removal device can be replaced or repaired may be added. In this case, the first trader selection unit 14 and the second trader selection unit 24 may be integrated to form one trader selection unit.

<9> In the first embodiment, the system 10 detects a failed state or a quasi-failed state among a plurality of vehicle engines 101 constituting the engine-type power generation device 100, and detects the engine to be replaced. The management system that supports the replacement will be described. In the second embodiment, in addition to the replacement of the replacement-required engine, the CO ₂ removal device 207 constituting the engine-type power generation device 100 is in a faulty state or _{A management system that detects a defective CO 2} removal device that has become a quasi-failure state and supports its replacement or repair has been described. However, the system 10 or 20 is an engine other than the _{vehicle engine 101 and the CO 2 removal device 207.} It may have a function of managing replacement or repair of other parts constituting the type power generation device 100.

<10> In the third embodiment, when one or more of the plurality of vehicle engines 101 are detected as replacement-requiring engines by the replacement-requiring engine detection process described in the first embodiment, Instead of newly selecting the engine that needs to be stopped, instead of the detected engine that needs to be replaced, the same number of engines that need to be restarted as the number of engines that need to be replaced are stepped out of the vehicle engines 101 that have been suspended by the engine selection process. It is preferable to select in the same manner as in # 76 and restart the operation promptly.

<11> In the first to third embodiments, it is assumed that the plurality of vehicle engines 101 and the generators 102 constituting the engine-type power generators 100, 200, and 300 are the same number, but at least some engine types are used. In the power generators 100, 200, and 300, one generator 102 is assigned to two or more of a part or all of the plurality of vehicle engines 101, and the plurality of vehicle engines 101 are synchronized with each other. One generator 102 may be driven in parallel. However, if one of the two or more vehicle engines 101 that perform the parallel drive is detected as a replacement engine, the spare vehicle engine is the rest of the two or more vehicle engines 101 that perform the parallel drive. The generator 102 can be driven in parallel in synchronization with the vehicle engine 101 of the above. Further, in at least some of the engine-type power generators 100, 200, and 300, in some or all of the plurality of vehicle engines 101, two or more generators 102 are assigned to one vehicle engine 101. The vehicle engine 101 may be configured to drive the two or more generators 102 in parallel.

<12> In the first to third embodiments, a management system is assumed in which the replacement of parts of the vehicle engines 101 and the like is centrally managed for the plurality of engine-type power generation devices 100 and 200. The systems 10, 20, and 30 can also manage the replacement of parts such as the vehicle engine 101 for one engine-type power generation device 100, 200. In this case, the systems 10, 20, and 30 can be provided adjacent to the engine-type power generation devices 100, 200, and the data communication line network 300 such as the Internet described above can be provided with the systems 10, 20, 30.
