The following describes an embodiment of the present invention with reference to the drawings. The following shows a schematic view of the scope of the description necessary to achieve the object of the present invention, and mainly describes the scope of the description necessary to explain the relevant parts of the present invention. The parts that are omitted are based on publicly known technology.

(Data Management System)
1 is an overall configuration diagram showing an example of a data management system 1 according to an embodiment of the present invention. The data management system 1 functions as a system for managing a fluid pressure driven valve 10 as an example of equipment. The data management system 1 mainly includes a fluid pressure driven valve 10 as a measurement target, a physical quantity measuring device 2 for measuring the physical quantity of the fluid pressure driven valve 10, a mobile terminal device 3 used by a maintenance worker M (an inspector/repair worker of the fluid pressure driven valve 10, etc.) as an inputter, a data management device 4 configured to be able to communicate with the fluid pressure driven valve 10 and the mobile terminal device 3, etc. and used by a maintenance manager A (a manager of the inspection/repair worker, etc.), and an equipment manager terminal device 7 configured to be able to communicate with the data management device 4, etc. and used by an equipment manager U (a manager or owner of the fluid pressure driven valve 10, etc.) as a report target.

In this embodiment, the fluid pressure driven valve 10 is used as an example of the device, but the device is not limited to the fluid pressure driven valve 10, and general devices such as other valves such as breathing valves, rotating machines, tanks, etc. may be used. The device includes one or more components that make up the device. Details of the fluid pressure driven valve 10 will be described later.

The physical quantity measuring device 2 acquires physical quantity information obtained by measuring the physical quantities of the fluid pressure driven valve 10 or the components that make up the fluid pressure driven valve 10 that are the measurement target. The physical quantity measuring device 2 may be incorporated into the fluid pressure driven valve 10, or may be provided in the fluid pressure driven valve 10 as a device separate from the fluid pressure driven valve 10. The physical quantity information is, for example, measurement data obtained from various sensors installed in the fluid pressure driven valve 10, or processed data obtained by processing the measurement data. In this case, the physical quantity information may be measurement data obtained from the sensors (hereinafter, including processed data) recorded at a predetermined sampling period or sampling frequency.

The mobile terminal device 3 is a device used by a maintenance worker M located near the installation location of the fluid pressure driven valve 10, and is composed of, for example, a portable computer. Applications, browsers, and other programs are installed on the mobile terminal device 3, which accepts various input operations and displays various information on a display screen (such as an input screen for impression information). When the mobile terminal device 3 accepts an input operation of impression information by the maintenance worker M regarding the fluid pressure driven valve 10, it uploads the impression information, the input time when the impression information was input by the maintenance worker M, and device identification information for identifying the fluid pressure driven valve 10 as the input target of the impression information to the data management device 4.

The data management device 4 is configured, for example, by a server-type computer or a cloud-type computer. The data management device 4 has a management control unit 41 that creates management information by associating the physical quantity information received from the physical quantity measuring device 2 and the impression information and input time received from the mobile terminal device 3 by device or component identified based on the device identification information, and a management memory unit 42 that stores the management information created by the management control unit 41. The details of the data management device 4 will be described later.

The impression information may be voice data or character data (text data) intuitively expressed by the maintenance worker M about his/her impression of the fluid pressure driven valve 10. In the case of voice data, the mobile terminal device 3 preferably converts the voice data into character data. The impression information may also be biometric data such as the amount of sweating or heart rate of the maintenance worker M. In the case of biometric data, the mobile terminal device 3 preferably converts the biometric data into character data such as "abnormal" when the amount of sweating or heart rate is high, and "no abnormality" when the amount of sweating or heart rate is low. The input time may be obtained from a clock or the like built into the mobile terminal device 3.

The device identification information is information for identifying the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10. Examples of device identification information include, but are not limited to, a device identification number such as an ID number that is uniquely assigned to each fluid pressure driven valve 10 or each component of the fluid pressure driven valve 10, and terminal location information that identifies the location of the mobile terminal device 3.

The device identification number is obtained, for example, by the following method. For example, if the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10 has a code image (one-dimensional code, two-dimensional code, etc.) or an ID tag (RFID, etc.) that records the device identification number or the address of the information transmission destination, the mobile terminal device 3 may obtain the device identification number by using a code recognition function for a code image captured by the camera of the mobile terminal device 3 or a tag reading function for an ID tag. If the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10 has a sticker on which the device identification number is printed, the mobile terminal device 3 may obtain the device identification number by using a character recognition function for a sticker captured by the camera of the mobile terminal device 3. The mobile terminal device 3 may obtain the device identification number by accepting an input operation by the maintenance worker M to input the device identification number. As for the terminal location information, the mobile terminal device 3 may obtain the terminal location information by using a position detection function such as GPS, Wi-Fi, beacon, inertial navigation sensor, geomagnetic sensor, etc. of the mobile terminal device 3.

When the device identification information is a device identification number, the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10 is directly identified by the device identification number. When the device identification information is terminal location information, the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10 is indirectly identified by the terminal location information. Specifically, the maintenance manager A registers the registered location information of the fluid pressure driven valve 10 in advance in the data management device 4. The mobile terminal device 3 transmits the terminal location information as device identification information to the data management device 4 together with the impression information and the input time. The data management device 4 compares the terminal location information received from the mobile terminal device 3 with the registered location information of the fluid pressure driven valve 10 registered in advance, thereby identifying the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10 having registered location information closest to the terminal location information. In either case, the data management device 4 identifies the fluid pressure driven valve 10 or the component of the fluid pressure driven valve 10 that is the target of input of impression information from among the multiple fluid pressure driven valves 10 or the components of the multiple fluid pressure driven valves 10, based on the device identification information received from the mobile terminal device 3, and creates management information by associating the physical quantity information received from the physical quantity measuring device 2 with the impression information and input time received from the mobile terminal device 3.

The equipment manager terminal device 7 is a device used by the equipment manager U located in a remote location away from the installation location of the fluid pressure driven valve 10, and is configured, for example, as a stationary computer or a portable computer. The equipment manager terminal device 7 has applications, browsers, and other programs installed, accepts various input operations, and displays various information (management information, daily management reports, etc.) on the display screen.

Network 8 is configured by wired or wireless communication according to any communication standard, or a combination of wired and wireless communication. Specifically, for example, a standardized communication network such as the Internet, a communication network managed within a building such as a local network, or a combination of these communication networks can be used.

The data management system 1 may further include a machine learning device 5 that generates a learning model based on the management information created by the data management device 4, and an information processing device 6 that predicts the state of the hydraulically driven valve 10 using the learning model learned by the machine learning device 5.

The machine learning device 5 operates as the subject of the learning phase of machine learning, and for example, acquires a learning dataset used for machine learning created by the data management device 4 from physical quantity information and impression information associated with the physical quantity information, and generates a learning model used by the information processing device 6 through machine learning. The learned learning model is provided to the information processing device 6 via the network 8, a recording medium, etc.

The information processing device 6 operates as the subject of the inference phase of the machine learning, and predicts the state of the fluid pressure driven valve 10 from the physical quantity information during operation using the learning model generated by the machine learning device 5, and transmits the predicted state information of the fluid pressure driven valve 10 to at least one of the data management device 4 or the equipment administrator terminal device 7, etc.

Each of the devices 3 to 7 is, for example, a general-purpose or dedicated computer (see FIG. 5 described below), and is configured to be able to transmit and receive various types of data to and from each other via the network 8. Note that the number of the devices 3 to 7 is not limited to the example in FIG. 1, and may be one or more.

(Fluid pressure driven valve 10)
2 is a schematic diagram showing an example of the fluid pressure driven valve 10 according to the embodiment of the present invention. The fluid pressure driven valve 10 includes a main valve 30, a drive device 40, and a solenoid valve 50.

The fluid pressure driven valve 10 shown in FIG. 2 employs an airless close system. During normal operation, the main valve 30 is opened by supplying air A (intake air) from the air supply source 13 to the drive unit 40 via the solenoid valve 50, and during emergency stop or test operation, the main valve 30 is closed by discharging air A (exhaust air) from the drive unit 40 via the solenoid valve 50. Note that the fluid pressure driven valve 10 may employ an airless open system, in which case the main valve 30 is closed by supplying air A to the drive unit 40 and opened by discharging air A from the drive unit 40.

The fluid pressure driven valve 10 is provided with a first air pipe 130 connecting the air supply source 13 and the solenoid valve 50, and a second air pipe 131 connecting the solenoid valve 50 and the drive unit 40, as flow paths for air A. Note that the drive fluid is not limited to the above-mentioned air A, and may be other gases or liquids (e.g., oil).

The fluid pressure driven valve 10 is connected to a communication cable 140 that transmits and receives various data between the external device 14 and the solenoid valve 50, and a power cable 150 that supplies power from an external power source 15 to the solenoid valve 50.

The external device 14 is a device that transmits and receives various information to and from the fluid pressure driven valve 10. The external device 14 is composed of, for example, a computer for equipment management (including a local server and a cloud server), a computer for an operator, a storage device or storage medium for storing data, etc. Any communication standard may be adopted for communication between the external device 14 and the solenoid valve 50, and wireless communication may also be used. In this embodiment, the external device 14 corresponds to the data management device 4, etc.

The main valve 30 shown in FIG. 2 is a ball valve. The main valve 30 is specifically configured to include a valve box 32 disposed midway through the piping 11 and a ball-shaped valve element 31 rotatably mounted within the valve box 32, with the valve shaft 12 connected to the upper part of the valve element 31. As the valve shaft 12 is rotated from 0 degrees to 90 degrees, the valve element 31 rotates within the valve box 32, switching the main valve 30 between a fully open state (the state shown in FIG. 2) and a fully closed state. Note that the valve used as the main valve 30 is not limited to a ball valve, and may be, for example, a butterfly valve or other on-off valve.

The drive device 40 shown in FIG. 2 employs a single-acting air cylinder mechanism. The drive device 40 includes, as its specific configuration, a cylinder 400 having a spring chamber 470 and a cylinder chamber 480, a pair of pistons 420A, 420B connected via a piston rod 410 that is arranged so as to be capable of linearly reciprocating within the cylinder 400, a coil spring 430 arranged in the spring chamber 470 on the first piston 420A side, an air supply/discharge port 440 connected to the cylinder chamber 480 on the second piston 420B side, and a transmission mechanism 450 arranged at a portion where the valve shaft 12 arranged to penetrate the cylinder 400 in the radial direction and the piston rod 410 intersect at right angles. Note that the drive device 40 is not limited to a single-acting type, and may be configured in other forms, such as a double-acting type.

The first piston 420A is biased by the coil spring 430 in the direction of closing the main valve 30. The second piston 420B is pressed in the direction of opening the main valve 30 against the biasing force of the coil spring 430 by air A (supply air) supplied from the air supply/discharge port 440. The transmission mechanism 450 is composed of a rack and pinion mechanism, a Scotch yoke mechanism, a link mechanism, a cam mechanism, etc., and converts the reciprocating linear motion of the piston rod 410 into rotational motion and transmits it to the valve shaft 12.

The solenoid valve 50 shown in FIG. 2 is a three-way solenoid valve with two positions and a normally closed type (open when energized, closed when de-energized). The solenoid valve 50 is specifically configured with a spool section 510 that switches the flow path through which air A flows, a solenoid section 520 that displaces the spool section 510 depending on the energized state (when energized or de-energized), and a sensor group 530 that measures the physical quantities and state quantities of each part of the solenoid valve 50. Note that the solenoid valve 50 is not limited to a three-way solenoid valve with two positions and a normally closed type, but may be a three-position type, a normally open type, a four-way solenoid valve, etc., and may be configured in various configurations based on any combination.

The accommodating section 500 functions as a housing for the indoor or explosion-proof solenoid valve 50. The accommodating section 500 has an axis insertion port 501 into which the valve axis 12 (third axis 12c) is inserted, and a cable insertion port 502 into which the communication cable 140 and the power cable 150 are inserted.

The spool section 510 has an input port 511 connected to the air supply source 13 via a first air pipe 130, an output port 512 connected to the drive unit 40 via a second air pipe 131, and an exhaust port 513 that discharges exhaust air from the drive unit 40.

When energized, the solenoid portion 520 displaces the spool portion 510 so as to connect the input port 511 and the output port 512, and when de-energized, the solenoid portion 520 displaces the spool portion 510 so as to connect the output port 512 and the exhaust port 513.

The sensor group 530 is arranged at various locations inside the storage section 500. The sensor group 530 includes, for example, a first pressure sensor 531 that measures the fluid pressure of air A flowing through a first flow path 503 that communicates with the input port 511, a second pressure sensor 532 that measures the fluid pressure of air A flowing through a second flow path 504 that communicates with the output port 512, and a main valve opening sensor 533 that measures the rotation angle when the valve shaft 12 (third shaft 12c) rotates and acquires valve opening information of the main valve 30 according to the rotation angle.

The main valve opening sensor 533 is, for example, a magnetic sensor that measures the strength of the magnetic field generated by the permanent magnet 120 attached to the valve shaft 12 (third shaft 12c) and obtains valve opening information for the main valve 30 according to the magnetic field strength.

The valve shaft 12 is formed in a rotatable shaft shape and is composed of a first shaft 12a, a second shaft 12b, and a third shaft 12c. Both ends of the first shaft 12a are connected to the second shaft 12b and the third shaft 12c, respectively, via couplings, connectors, etc., and the first shaft 12a, the second shaft 12b, and the third shaft 12c are arranged coaxially. The first shaft 12a is arranged to pass through the drive unit 40 and is driven by the drive unit 40. The second shaft 12b is connected to the first shaft 12a and is connected to the main valve 30. The third shaft 12c is connected to the first shaft 12a and is inserted into the housing portion 500 of the solenoid valve 50 and supported therein. The valve shaft 12 rotates as a whole in synchronization with the drive of the first shaft 12a by the drive unit 40.

In the fluid pressure driven valve 10 having the above configuration, when the solenoid valve 50 is in an energized state, air A (supply air) from the air supply source 13 flows through the first air pipe 130, the input port 511, the output port 512, and the second air pipe 131 in that order, and is supplied to the air supply/discharge port 440, thereby pressing the second piston 420B and compressing the coil spring 430. Then, when the first shaft 12a (valve shaft 12) is rotated via the piston rod 410 and the transmission mechanism 450 by the amount that the piston rod 410 has moved in response to the compression of the coil spring 430, the valve body 31 rotates within the valve box 32, and the main valve 30 is operated to a fully open state.

On the other hand, when the solenoid valve 50 is in a non-energized state, the air A (exhaust) in the cylinder 400 flows from the air supply/exhaust port 440 through the second air pipe 131, the output port 512, and the exhaust port 513 in that order, and is discharged to the outside air, reducing the pressing force of the second piston 420B and causing the coil spring 430 to recover from its compressed state. Then, when the first shaft 12a (valve shaft 12) is rotated via the transmission mechanism 450 by the amount of movement of the piston rod 410 in response to the recovery of the coil spring 430, the valve body 31 rotates within the valve box 32, and the main valve 30 is operated to a fully closed state.

Figure 3 is a schematic block diagram showing an example of a fluid pressure driven valve 10 according to an embodiment of the present invention. As shown in Figure 3, the solenoid valve 50 includes, as an example of an electrical configuration, a control unit 540 that controls the solenoid valve 50, a communication unit 550 for communicating with an external device 14, and a power supply circuit unit 560 that is connected to an external power supply 15, in addition to the solenoid unit 520 and the sensor group 530 described above.

In addition to the first pressure sensor 531, the second pressure sensor 532, and the main valve opening sensor 533, the sensor group 530 includes a voltage sensor 534 that measures the voltage supplied to the solenoid section 520, a current/resistance sensor 535 that measures the current value when the solenoid section 520 is energized and the resistance value when the solenoid section 520 is not energized, a temperature sensor 536 that measures the internal temperature of the storage section 500, and a magnetic sensor 537 that measures the strength of the magnetic field generated by the solenoid section 520.

The sensor group 530 also includes an operating time meter (timer) 538 that measures at least one of the total time that current is applied to the solenoid section 520 and the current time that current is applied as the operating time of the fluid pressure driven valve 10 as a sensor group that acquires information regarding the operating history of each section, and an operation counter (counter) 539 that counts the number of times that the solenoid valve 50, the drive unit 40, and the main valve 30 are each operated.

The sensor group 530 is not limited to sensors provided separately as described above, and a specific sensor may also serve the functions of other sensors, so that the other sensors do not have to be provided separately. For example, the magnetic sensor 537 measures the strength of the magnetic field generated by the solenoid unit 520 and calculates the current value when electricity is applied to the solenoid unit 520 based on the magnetic field strength, so that the current/resistance sensor 535 does not have to be provided separately. The controller 541 may also incorporate the function of a sensor or realize part of the function of a sensor. For example, the controller 541 may incorporate an operating hour meter 538 and an operation counter 539, so that the operating hour meter 538 and the operation counter 539 do not have to be provided separately.

The control unit 540, the communication unit 550, and the power circuit unit 560 are configured, for example, by a general-purpose or dedicated computer (see FIG. 5 described below).

The control unit 540 processes information indicating the physical quantities and state quantities of each part of the fluid pressure driven valve 10 measured by the sensor group 530, and is equipped with a controller 541 that controls each part of the fluid pressure driven valve 10, and a valve test switch 542 that controls the electrified state of the solenoid unit 520 and opens and closes the main valve 30 during test operation.

The controller 541 incorporates, for example, a state determination device 70, and includes a function for realizing the state determination device 70. Note that all or part of the configuration of the state determination device 70 may be realized by other equipment, for example, the external device 14 or another device (for example, the information processing device 6) connected to the fluid pressure driven valve 10.

When the specified test operation conditions are met, the valve test switch 542 receives a command from the controller 541 and executes a stroke test of the fluid pressure driven valve 10 as a test operation to perform a specified opening and closing operation.

The stroke test is performed, for example, by either a full stroke test or a partial stroke test. The full stroke test is performed by switching the main valve 30 from a conducting state to a non-conducting state in the fully open state to operate it to the fully closed state, and then switching it from a non-conducting state to a conducting state in the fully closed state to return it to the fully open state. The partial stroke test is performed by switching the main valve 30 from a conducting state to a non-conducting state in the fully open state to partially close it to a predetermined opening degree without operating the main valve 30 to the fully closed state (i.e., without stopping the equipment), and then switching it from a non-conducting state to a conducting state in the partially closed state to return it to the fully open state.

As for the test operation conditions, for example, when the execution time based on the execution frequency (e.g., once a year) set by the administrator or a specific specified date and time arrives, when an execution command is received from the external device 14, or when a test execution button (not shown) provided on the solenoid valve 50 is operated by the administrator, the test operation conditions are met and a test operation (stroke test) is executed.

The sensor group 530 of the fluid pressure driven valve 10 constitutes the physical quantity measuring device 2 shown in FIG. 1. The physical quantity to be measured by the physical quantity measuring device 2 is, for example, pressure, valve opening, voltage, current, temperature, etc. The physical quantity measuring device 2 is composed of, for example, the first pressure sensor 531, the second pressure sensor 532, the main valve opening sensor 533, the voltage sensor 534, the current/resistance sensor 535, the temperature sensor 536, and the magnetic sensor 537 shown in the sensor group 530. Note that the physical quantity to be measured is not limited to the above example, and may be, for example, physical quantities such as acceleration (vibration), speed, displacement, environmental sound, and load. In that case, a physical quantity measuring device 2 such as an acceleration sensor, a speed sensor, a displacement sensor, a sound sensor, or a load sensor is used. The physical quantity measuring device 2 may also include multiple sensors to measure multiple physical quantities. The physical quantity measuring device 2 processes physical quantity information in which an analog signal indicating the measured physical quantity is converted into a digital signal. The processed physical quantity information is used by the data management device 4.

(Data management device (cloud))
4 is a schematic block diagram showing an example of a data management device 4 according to an embodiment of the present invention. The data management device 4 includes, as its main components, a management control unit 41, a management storage unit 42, a management communication unit 43, a management input unit 44, and a management output unit 45.

The management control unit 41 functions as the management processing unit 41a, for example, by executing the data management program 42a stored in the management storage unit 42. The management communication unit 43 functions as a communication interface that transmits and receives various data between, for example, the physical quantity measuring device 2, the mobile terminal device 3, and the device manager terminal device 7, etc., via the network 8. The management storage unit 42 stores various data, various programs (such as the data management program 42a) and data (such as the management setting information 42b) used in the operation of the data management device 4. The management setting information 42b is various setting parameters referenced by the management control unit 41 when the data management device 4 operates. As shown in FIG. 4, the management setting information 42b includes, for example, the registered location information of the device or component and the device identification number corresponding to the registered location information, for each device or component. The registered location information may be latitude and longitude, or may be a predetermined unique data format. The management input unit 44 and management output unit 45 function as a user interface by accepting input operations from the maintenance manager A and outputting various information via a display screen or audio.

The management processing unit 41a creates management information by associating the physical quantity information acquired from the physical quantity measuring device 2 with the impression information and input time acquired from the mobile terminal device 3 based on the device identification information acquired from the mobile terminal device 3. For example, when the physical quantity measuring device 2 and the mobile terminal device 3 start communication with the management processing unit 41a via the management communication unit 43 and receive the impression information, input time, device identification information, and the like from the mobile terminal device 3, the management processing unit 41a executes management processing to create management information.

As a management process, the management processing unit 41a identifies the device or component that is the input target of the impression information based on the device identification information. The management processing unit 41a creates management information by associating physical quantity information of the device or component identified based on the device identification information as the measurement target with the impression information and the input time acquired together with the device identification information. In this case, the management processing unit 41a may create management information that associates physical quantity information that measures the physical quantity during a predetermined period including the input time acquired together with the device identification information, and the impression information acquired together with the device identification information, with the measurement target of the device or component identified based on the device identification information.

The management information created by the management processing unit 41a is sent to the device administrator terminal device 7. The management information may be stored in the management storage unit 42 and made accessible by an application, browser, etc. Furthermore, the management control unit 41 may analyze the management information and perform a detailed diagnosis.

(Various information)
Fig. 6 is a diagram showing an example of a data format of management information created by the data management device 4 according to the present embodiment. Fig. 7 is a diagram showing an example of a device identification number according to the present embodiment. Fig. 8 is a diagram showing an example of impression information according to the present embodiment.

The management information created by the data management device 4 of this embodiment is associated with, for example, the device identification number, input time, impression information, physical quantity information, etc., as shown in FIG. 6. That is, the management information is associated with the impression information input by the maintenance worker M and the physical quantity information at the input time when the impression information is input, for the fluid pressure driven valve 10 with the device identification number specified by the device identification information. Note that FIG. 7 illustrates a case in which the management information for the fluid pressure driven valve 10 with the device identification number "MA100", the fluid pressure driven valve 10 with the device identification number "MA200", and the fluid pressure driven valve 10 with the device identification number "MA300" are managed in three table formats, but the management information for the other fluid pressure driven valves 10 is created in the same manner. Note that the data format is not limited to the table format and may be changed as appropriate. In addition, the management information may be associated with, for example, the terminal position information acquired as the device identification information, or the maintenance worker identification number uniquely assigned to the maintenance worker M who inputs the impression information.

As shown in FIG. 7, the device identification number is an ID number or the like that is uniquely assigned to each fluid pressure driven valve 10 or each component of the fluid pressure driven valve 10. The device identification number is identified directly or indirectly based on the device identification information.

The input time is the time when the maintenance worker M inputs the impression information. The input time is obtained, for example, from a clock built into the mobile terminal device 3.

The impression information is information input by the maintenance worker M as shown in Fig. 8, and is, for example, information such as "no abnormality", "abnormality", "abnormal sound", "something is wrong", etc. The impression information is voice data uttered by the maintenance worker M, character data converted from the voice data, character data input by the maintenance worker M, selection data selected by the maintenance worker M from a set phrase or option in advance, biometric data such as the amount of sweat and heart rate of the maintenance worker M, character data converted from the biometric data, etc. The impression information may be one of these, or an arbitrary combination of these.

The physical quantity information is, for example, measurement data obtained by measuring various physical quantities using the sensor group 530 of the fluid pressure driven valve 10 to be measured. The physical quantity information may be measurement data measured by all sensors in the sensor group 530, or may be measurement data measured by a specific sensor (which may be one or more) selected from the sensor group 530. In this case, the specific sensor may be selected in advance by the maintenance manager A, or may be selected according to the content of the impression information. For example, if the impression information includes content related to "abnormal sound", an acceleration sensor or a sound sensor may be selected. The physical quantity information may also be measurement data obtained by measuring various physical quantities during a predetermined period including the input time. In this case, the predetermined period including the input time may be a period between a pre-input time before the input time and the input time, a period between the input time and a post-input time after the input time, or a period between a pre-input time and a post-input time. The predetermined period may be determined in advance by the maintenance manager A, or may be determined according to the content of the impression information. For example, if the impression information includes information about an "abnormal sound," the period required to analyze the abnormal sound may be determined.

(Management daily report)
FIG. 9 is a diagram showing an example of a daily management report created from management information that can be acquired by the data management system 1 according to this embodiment.

The data management device 4 of this embodiment uses the above-mentioned management information to create a management daily report using a template predetermined for each equipment manager U. For example, as shown in FIG. 9, the management daily report is created by including the physical quantity information acquired from the physical quantity measuring device 2, the impression information and input time acquired from the mobile terminal device 3, and the equipment identification number indicating the equipment or equipment components identified based on the equipment identification information acquired from the mobile terminal device 3. The equipment manager U can view the management daily report created by the data management device 4 using an app, browser, or the like installed on the equipment manager terminal device 7. The equipment manager U can also download the management daily report created by the data management device 4 in a file format such as PDF.

In the daily management report shown in FIG. 9, when maintenance worker M inspected the valve at 9:00, it was determined that there was "no abnormality" and it was determined that the fluid pressure valve 10 was operating normally. When maintenance worker M inspected the valve at 13:00, it was determined that there was "something wrong" and it was determined that there was something wrong with the fluid pressure valve 10. When maintenance worker M inspected the valve at 17:00, it was determined that there was "something wrong" and it was determined that there was something wrong with the fluid pressure valve 10.

In this way, the data management device 4 acquires physical quantity information obtained by measuring the physical quantities of the fluid pressure driven valve 10 that is the measurement target, impression information indicating the impression of the person inputting the information about the fluid pressure driven valve 10, the input time when the impression information was input, and equipment identification information for identifying the fluid pressure driven valve 10 as the input target of the impression information, and creates management information for the fluid pressure driven valve 10 that associates the physical quantity information of the fluid pressure driven valve 10 identified based on the equipment identification information with the impression information acquired together with the equipment identification information and the input time, so that a report can be made that associates the state of the equipment with the impression of the maintenance worker M.

In addition, the data management device 4 creates a daily management report based on a template predetermined for each device administrator U from the management information, making it possible to create a daily management report that is easy to view and use for each device administrator U.

(Data Management Method of the First Embodiment)
10 is a flowchart showing an example of a data management method executed by the data management system 1 according to the first embodiment. The flowchart of the present embodiment is executed by the physical quantity measuring device 2, the mobile terminal device 3, the data management device 4, the device manager terminal device 7, etc.

In the data management method of the first embodiment, first, in step S311, the mobile terminal device 3 acquires impression information from the maintenance worker M. Then, the mobile terminal device 3 acquires an input time indicating the current time, and terminal location information that identifies the location of the mobile terminal device 3 (maintenance worker M) at that time as device identification information.

Next, in step S312, the mobile terminal device 3 uploads (transmits) the impression information, the input time of the impression information, and the terminal location information as device identification information to the data management device 4 (cloud).

Next, in step S411, the data management device 4 receives (acquires) the impression information, the input time, and the terminal location information. The data management device 4 then compares the registered location information of the fluid pressure driven valve 10 previously registered in the management setting information 42b (see FIG. 4) with the terminal location information received from the mobile terminal device 3, and identifies the device identification number of the fluid pressure driven valve 10 having registered location information closest to the terminal location information as the input target for the impression information. For example, if the registered location information closest to the terminal location information received from the mobile terminal device 3 is "Aa10", the device identification number "MA100" corresponding to the registered location information "Aa10" is identified as the fluid pressure driven valve 10 that is the input target for the impression information.

Next, in step S412, the data management device 4 requests the physical quantity measuring device 2 provided in the fluid pressure driven valve 10 identified by the device identification number identified in step S411 to transmit physical quantity information. Next, in step S211, the physical quantity measuring device 2 notifies the data management device 4 of the physical quantity information in response to the request from the data management device 4.

Next, in step S413, the data management device 4 receives (acquires) physical quantity information for measuring the fluid pressure driven valve 10 indicated by the device identification number identified based on the terminal location information. Then, in step S414, the data management device 4 creates management information that associates the physical quantity information, the device identification number identified based on the terminal location information, and the impression information and input time received together with the device identification information.

Next, in step S415, the data management device 4 creates a daily management report based on a template predetermined for each equipment manager U from the management information created in step 414. At this time, the template used is a template for the equipment manager U of the fluid pressure driven valve 10 that is the target of input of impression information. The data management device 4 then transmits the daily management report to the equipment manager terminal device 7 used by the equipment manager U of the fluid pressure driven valve 10 that is the target of input of impression information. Next, in step S511, the equipment manager terminal device 7 receives the daily management report and displays it, for example, on a display screen.

In this way, according to the data management method of this embodiment, management information for the fluid pressure driven valve 10 is created that associates physical quantity information of the fluid pressure driven valve 10 identified based on the terminal location information with the impression information and input time acquired together with the terminal location information, so that a report can be made that associates the equipment status with the impression of the maintenance worker M.

(Data Management Method of the Second Embodiment)
11 is a flowchart showing an example of a data management method executed by the data management system 1 according to the second embodiment. The flowchart of the present embodiment is executed by the physical quantity measuring device 2, the mobile terminal device 3, the data management device 4, the device manager terminal device 7, etc.

In the data management method of the second embodiment, first, in step S321, the mobile terminal device 3 acquires impression information from the maintenance worker M. Then, the mobile terminal device 3 acquires an input time indicating the current time, and, as device identification information, an equipment identification number indicating the fluid pressure driven valve 10 to which the impression information is to be input at that time.

Next, in step S322, the mobile terminal device 3 uploads (transmits) the impression information, the input time of the impression information, and the device identification number as device-specific information to the data management device 4 (cloud).

Next, in step S421, the data management device 4 receives (acquires) the impression information, the input time, and the device identification number.

Next, in step S422, the data management device 4 requests the physical quantity measuring device 2 provided in the fluid pressure driven valve 10 indicated by the device identification number received in step S421 to transmit physical quantity information. Next, in step S221, the physical quantity measuring device 2 notifies the data management device 4 of the physical quantity information in response to the request from the data management device 4.

Next, in step S423, the data management device 4 receives (acquires) physical quantity information for the fluid pressure driven valve 10 indicated by the device identification number as the measurement target. Then, in step S424, the data management device 4 creates management information that associates the physical quantity information, the device identification number, and the impression information and input time received together with the device identification number.

Next, in step S425, the data management device 4 creates a daily management report based on a template predetermined for each equipment manager U from the management information created in step 424. At this time, the template used is a template for the equipment manager U of the fluid pressure driven valve 10 for which the impression information is to be input. The data management device 4 then transmits the daily management report to the equipment manager terminal device 7 used by the equipment manager U of the fluid pressure driven valve 10 for which the impression information is to be input. Next, in step S521, the equipment manager terminal device 7 receives the daily management report and displays it, for example, on a display screen.

In this way, according to the data management method of this embodiment, management information is created that associates physical quantity information of the fluid pressure driven valve 10 identified based on the equipment identification number with the impression information and input time acquired together with the equipment identification number, so that a report can be made that associates the equipment status with the impression of the maintenance worker M.

(Annotation for machine learning)
FIG. 12 is a diagram showing an example in which management information created by the data management system 1 according to this embodiment is used for annotation for machine learning.

The physical quantity information and the impression information associated by the data management system 1 may be used for annotation for machine learning. The data management system 1 of this embodiment creates, for example, physical quantity information to which a normal label is assigned and physical quantity information to which an abnormal label is assigned based on the impression information associated with the physical quantity information, thereby creating a learning dataset for a classification problem in supervised learning. Note that instead of classifying by assigning two classes of labels, a normal label and an abnormal label, classification may be performed by assigning labels for multiple classes of three or more classes. That is, in annotation using management information, a learning dataset for any classification problem can be created by preparing labels for each class according to the contents of the impression information.

When creating a learning dataset, it is preferable that the physical quantity information is measurement data obtained by measuring the physical quantities of the fluid pressure driven valve 10 or its components during a specified period including the input time, and the impression information includes information that represents the state of the fluid pressure driven valve 10 or its components. In this case, a learning dataset to be used in machine learning is created by linking and classifying the physical quantity information with a label based on the impression information associated with the physical quantity information. In this way, linking the physical quantity information, for which the period for measuring the physical quantity is specified, with a label based on the impression information is effective for annotation in a learning model for a classification problem, and makes it easy to create a learning dataset.

For example, as shown in FIG. 8, the impression information is roughly divided into "no abnormality" and "abnormality". The data management device 4 creates data in which the physical quantity information is labeled with "no abnormality" or "abnormality" for each event. Machine learning may be performed by the machine learning device 5 of the data management system 1 according to this embodiment or an external machine learning device using the labeled data. The machine learning method and the configuration of the learning model may be selected as appropriate.

The "abnormal" label may be further subdivided into "abnormal 1" and "abnormal 2", etc. For example, "abnormal 1" may be a stage where an abnormality is likely, such as "something feels strange" or "something is wrong", and "abnormal 2" may be a stage where an abnormality is definitely present, such as "abnormality" or "abnormal noise". Abnormalities may also be further subdivided to identify specific locations or causes, such as "cylinder abnormality" or "external air leak".

In this way, the data management system 1 of this embodiment creates a learning data set used for machine learning from physical quantity information and subjective information associated with the physical quantity information, making it possible to efficiently learn a supervised learning model for condition diagnosis (e.g., abnormality diagnosis). In other words, a learning model that reflects the know-how of an experienced maintenance worker M can be efficiently created.
