Description

  The present invention relates to a technique for performing inspection work and maintenance work on high-pressure gas equipment using smart devices such as smartphones and tablets.

  The high-pressure gas stored in the high-pressure gas equipment undergoes various state changes due to changes in the environment and operating conditions. There are various types of high-pressure gas equipment such as low-temperature liquefied gas storage tanks and cylinder cabinets (see, for example, Patent Document 1).

  In such a high-pressure gas facility, equipment may be loaded due to various factors while being used, and some abnormality may occur. In order to detect these abnormalities at an early stage, the high-pressure gas equipment must be regularly inspected. For such inspections, the frequency, timing, inspection points such as inspection items, etc. are determined based on related laws and regulations. There are two types of inspections for high-pressure gas equipment: daily inspections with a fixed time every day and periodic inspections with a certain period of time. For example, in daily inspection, an operator records the reading of numerical values of various instruments and the presence or absence of an appearance abnormality by handwriting on a paper inspection table at the inspection site. Then, after the inspection, the operator took the inspection table back to the office and transcribed it into the ledger or entered it into the computer system. In addition, a high-pressure gas facility inspection management support system that creates a report or application using the data of these inspection tables has also been proposed (see, for example, Patent Document 3).

[Outline]
FIG. 1 is a diagram illustrating an outline of a conventional operation flow relating to inspection of a high-pressure gas facility. An inspection operation 100 in the figure represents an inspection operation of a high-pressure gas facility to be managed. The inspection operation 100 is an operation at a site where a high-pressure gas facility to be inspected (hereinafter referred to as “inspection target facility”) is installed. The post-operation 200 represents a post-operation performed after the inspection operation 100 is completed after the inspection operator returns to the office from the inspection site.

  In the inspection of conventional high-pressure gas equipment, an inspection worker first goes to the site where the equipment to be inspected is installed and performs the inspection work 100. In the inspection operation 100, the inspection operator visually confirms the equipment to be inspected on site for inspection items set in advance. The inspection operator enters the contents of the inspection items visually confirmed on the paper inspection table. The inspection operator carries out such visual inspection of the inspection object and filling in the inspection table for all inspection items. The inspection person returns to the office after completing the on-site inspection work 100 and performs the post-operation 200.

  FIG. 2 is a diagram showing a specific example of an inspection table for high-pressure gas equipment. In FIG. 2, each item numbered 1 to 18 is an inspection item. Details of each inspection item will be described later if necessary. The inspection operator needs to carry out inspection of such many items for each high-pressure gas facility to be managed, and the inspection of each facility needs to be performed at a predetermined timing and at a frequency more than a predetermined frequency. . For example, according to the “CE Installation / Raleigh Service Establishment Standard (JIGA-TS / 11/04 Revised)”, inspection of CE (Cold Evaporator: Ultra Low Temperature Liquefied Gas Storage Tank) equipment is performed immediately after the start of operation and when the operation is stopped. In addition to the above, there are implementation standards that should be implemented at least once a day. However, in the inspection work using such a paper inspection table, there is a possibility that defects such as omission of description of inspection results, description errors, and mistakes of inspection objects may occur.

  Returning to the description of FIG. In the subsequent operation 200, the inspection operator arranges information by transferring the contents of the inspection table brought back to the office to the ledger or inputting it to the management system. However, the inspection operator may find deficiencies in the inspection operation 100 at the time of the post-operation 200. For example, a description omission or a description mistake in the inspection operation 100 is detected. In addition, if the inspection table is stored in a poor state, it may be difficult to later determine the contents described in the inspection table even if there are no omissions or mistakes during the on-site inspection. As described above, when the inspection work 100 is defective, the inspection work 100 needs to be redone. If such a deficiency is discovered during an on-site inspection, the inspection operator may re-inspect the inspection from the beginning. However, when the inspection work at the site is once completed and the deficiencies are discovered after the inspection worker returns to the office etc., the inspection worker needs to visit the site again and repeat the inspection work. .

  The inspection work for high-pressure gas equipment is mainly performed by the gas consumers. For this reason, as described above, conventional operations in which on-site inspection work is performed only by human visual inspection and manual entry are factors that increase the operational load on gas consumers. In addition, if a lot of inspection work is inadequate, the information in the management system may not be updated at an appropriate timing. And such a delay in information update timing may increase the operational load on the gas consumer. For example, this is a case where the gas consumer determines the gas ordering timing based on the inspection result accumulated in the management system. In this case, when the inspection work is re-executed, reflection of the latest inspection result to the management system may be delayed, and gas ordering may be delayed.

  Hereinafter, the high-pressure gas that has made it possible to reduce the operational burden on the consumer and the supplier of gas supply and demand by providing a configuration that enables the inspection work of the high-pressure gas facility to be carried out more reliably. Details of the embodiment of the facility management system will be described.

[Details]
FIG. 3 is a schematic diagram illustrating a configuration example of the high-pressure gas facility management system 10 according to the first embodiment. The high pressure gas equipment management system 10 includes an inspection terminal 1 and a management server 2. The inspection terminal 1 is a terminal device used for inspection work by an inspection operator at an inspection site. The inspection operator inputs the inspection result of each inspection item to the inspection terminal 1. For example, the inspection operator activates a predetermined application (hereinafter referred to as “inspection tool”) installed in advance on the inspection terminal 1 to enter a screen (hereinafter referred to as “input”) on the inspection terminal 1. Screen "). The inspection operator inputs the inspection result on the input screen displayed on the inspection terminal 1.

  The inspection terminal 1 transmits the content input by the inspection operator to the management server 2 as inspection information. For example, the inspection terminal 1 communicates with the management server 2 via the mobile communication network 4. The inspection terminal 1 may be configured using any information processing device as long as it can communicate with the management server 2. However, considering the use for the inspection work, the inspection terminal 1 is a tablet having excellent portability and a wireless communication function. In general, it is configured using a mobile terminal such as a smartphone or a mobile phone. In addition, although the one inspection terminal 1 is shown by FIG. 3, more than one may be sufficient.

  The management server 2 acquires inspection information from the inspection terminal 1. For example, the management server 2 is connected to an office LAN 3 installed in the office, and communicates with the inspection terminal 1 via the mobile communication network 4. The management server 2 stores the inspection information acquired from the inspection terminal 1 in association with the equipment to be inspected.

  FIG. 4 is a diagram illustrating a specific example of the input screen. For example, the input screen 300 in FIG. 4 includes a first input area 310, a second input area 320, and a third input area 330. In the first input area 310, the second input area 320, and the third input area 330, objects such as text boxes and check boxes (hereinafter referred to as “input objects”) that accept input of information are displayed. For example, the first input area 310 is an area that receives an input of the inspection target facility. In the example of FIG. 4, a pull-down menu 311 is displayed in the first input area 310 as an input object that receives an input for selecting an inspection target facility.

  For example, the 2nd input field 320 is a field which receives the input of the inspection result of each inspection item. In the example of FIG. 4, text boxes 321 to 325 are displayed in the second input area 320 as input objects that accept inspection result inputs as character strings. Text boxes 321 to 325 are input objects for each corresponding check item. The third input area 330 is an area that receives an input of an instruction for causing the management server 2 to transmit information input on the input screen as inspection information. In the example of FIG. 4, a transmission button 331 is displayed as an input object that receives an input of an inspection information transmission instruction.

  For example, the inspection operator selects an inspection target facility that he / she wants to start the inspection operation from the pull-down menu 311 and inputs the inspection result of each inspection item in the text boxes 321 to 325. When the inspection operator finishes inputting inspection results for all the inspection items, the inspection operator presses a transmission button 331 to transmit inspection information to the management server 2.

  FIG. 5 is a functional block diagram showing a functional configuration of the management server 2 in the high pressure gas equipment management system 10 of the first embodiment. The management server 2 includes a CPU (Central Processing Unit), a memory, an auxiliary storage device, and the like connected by a bus, and executes a management server program. The management server 2 functions as a device including the communication unit 21, the storage unit 22, the inspection information providing unit 24, and the inspection information acquiring unit 23 by executing the management server program. All or some of the functions of the management server 2 may be realized by using hardware such as an application specific integrated circuit (ASIC), a programmable logic device (PLD), or a field programmable gate array (FPGA). The management server program may be recorded on a computer-readable recording medium. The computer-readable recording medium is, for example, a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, or a storage device such as a hard disk built in the computer system. The management server program may be transmitted via a telecommunication line.

  The communication unit 21 is a communication interface for the management server 2 to connect to the office LAN 3. The communication unit 21 communicates with the inspection terminal 1 via the office LAN 3 and the mobile communication network 4.

  The storage unit 22 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The storage unit 22 stores inspection information transmitted from the inspection terminal 1 and position information of each inspection target facility (hereinafter referred to as “inspection target position information”).

  The inspection information acquisition unit 23 acquires inspection information from the inspection terminal 1 via the communication unit 21 and stores it in the storage unit 22. The inspection information includes identification information of the inspection target equipment and information indicating the inspection result of the inspection target equipment.

  The inspection information providing unit 24 receives a request from the inspection terminal 1 via the communication unit 21, and transmits a part or all of the inspection information stored in the own device to the inspection terminal 1 in response to the received request. The inspection information providing unit 24 may transmit the inspection information stored in the own device to a device other than the inspection terminal 1.

  FIG. 6 is a functional block diagram showing a functional configuration of the inspection terminal 1 in the high-pressure gas equipment management system 10 of the first embodiment. The inspection terminal 1 includes a CPU (Central Processing Unit), a memory, an auxiliary storage device, and the like connected by a bus, and executes a terminal program. The inspection terminal 1 functions as a device including the communication unit 11, the display unit 12, the input unit 13, the position information acquisition unit 14, and the input screen control unit 15 by executing a terminal program. All or some of the functions of the inspection terminal 1 may be realized using hardware such as an application specific integrated circuit (ASIC), a programmable logic device (PLD), and a field programmable gate array (FPGA). The terminal program may be recorded on a computer-readable recording medium. The computer-readable recording medium is, for example, a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, or a storage device such as a hard disk built in the computer system. The terminal program may be transmitted via a telecommunication line.

  The communication unit 11 is a communication interface for connecting the inspection terminal 1 to the mobile communication network 4. The communication unit 11 communicates with the management server 2 via the mobile communication network 4.

  The display unit 12 is configured using a display device such as a CRT (Cathode Ray Tube) display, a liquid crystal display, or an organic EL (Electro-Luminescence) display. On the display unit 12, an inspection result input screen as illustrated in FIG. 4 is displayed.

  The input unit 13 is configured using an input device such as a mouse, a keyboard, a touch panel, or a voice input device. The input unit 13 receives an input operation of an inspection worker for the own device. The input unit 13 outputs information indicating an input operation by the user to the input screen control unit 15.

  The position information acquisition unit 14 acquires position information of the own apparatus (hereinafter referred to as “own apparatus position information”). For example, the position information acquisition unit 14 acquires position information by wireless communication with a GPS (Global Positioning System). The position information acquisition unit 14 outputs the acquired position information of the own device to the input screen control unit 15.

  The input screen control unit 15 is a functional unit that is generated when the inspection tool is activated. The inspection tool is activated by executing an inspection tool program (hereinafter referred to as “inspection tool program”). The inspection tool program is stored in advance in, for example, the auxiliary storage device described above. The inspection tool program is read from the auxiliary storage device and executed when the inspection operator performs a starting operation of the inspection tool. By starting the inspection tool, an input screen as illustrated in FIG. 4 is displayed on the display unit 12.

  The input screen control unit 15 controls the operation of the inspection terminal 1 related to the operation of the input screen. For example, the input screen control unit 15 controls processing such as displaying the input screen, checking information input to the input screen, and transmitting inspection information to the management server 2. Hereinafter, the process in which the input screen control unit 15 controls the operation of the inspection terminal 1 related to the operation of the input screen is referred to as an input screen control process. Specifically, the input screen control unit 15 includes a pre-confirmation information storage unit 151, an input control unit 152, an input determination unit 153, and an inspection information transmission unit 154, thereby realizing input screen control.

  The pre-confirmation information storage unit 151 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The pre-confirmation information storage unit 151 temporarily stores input information (hereinafter referred to as “pre-confirmation information”) of inspection results before confirmation. The pre-confirmation information is updated by the input control unit 152 in accordance with input of information for each item on the input screen.

  The input control unit 152 reflects the information input via the input unit 13 on the display of the input screen, and stores the inspection result input to each item in the pre-confirmation information storage unit 151 as pre-confirmation information. Further, the input control unit 152 updates the pre-confirmation information with new input information in response to input of information for each item on the input screen. When the operation for ending the input of the inspection result is input, the input control unit 152 notifies the inspection information transmitting unit 154 to that effect.

  The input determination unit 153 determines the validity of the input pre-confirmation information in accordance with the input of the pre-confirmation information for each item, and displays an indication prompting the inspection operator to correct based on the determination result (hereinafter referred to as “correction”). Notification display ”). This correction notification display may be displayed in a predetermined area in the input screen, or may be displayed on another screen such as a pop-up.

  The inspection information transmission unit 154 confirms the pre-confirmation information at that time as inspection information and transmits it to the management server 2 in response to an input of an operation for ending the input of the inspection result. At this time, the inspection information transmission unit 154 determines whether or not the pre-confirmation information satisfies a predetermined condition, and inspects the pre-confirmation information when it is determined that the pre-confirmation information satisfies the predetermined condition. Send as information.

  7 and 8 are flowcharts showing a specific example of the input screen control process. In FIG. 7, it is assumed that the input screen control process is started in a state where the initial input screen is displayed on the display unit 12 of the inspection terminal 1 by the activation of the inspection tool. First, the inspection operator inputs the inspection target equipment that he / she is about to start inspection on the input screen. Specifically, the inspection operator selects an inspection target facility from the list of high-pressure gas facilities displayed in the pull-down menu 311.

  The input unit 13 receives an input for selecting an inspection target facility (step S101). The input unit 13 outputs information indicating the selected inspection target facility (hereinafter referred to as “selection information”) to the input control unit 152.

  When acquiring the selection information from the input unit 13, the input control unit 152 acquires the current time as the inspection start time (step S102). The input control unit 152 acquires the position information (inspection target position information) of the inspection target facility indicated by the acquired selection information from the management server 2 (step S103).

  The input control unit 152 accepts input of inspection results on the input screen (step S104). The input control unit 152 determines whether or not an operation for ending the inspection result input is input (for example, whether or not the transmission button 331 is pressed) (step S105). When the operation for ending the input of the inspection result is not input (step S105—NO), the input determination unit 153 executes an input determination process for the input information (step S106). By this input determination process, the validity of the input information is determined, and a correction notification is displayed on the input screen according to the determination result. The input control unit 152 reflects the input information on the display of the input screen, and stores the input information in the pre-confirmation information storage unit 151 as pre-confirmation information (step S107). After storing the pre-confirmation information, the input control unit 152 moves the process to step S104 and repeats receiving inspection result input.

  On the other hand, when an operation for ending the input of the inspection result is input in step S105 (step S105-YES), the input control unit 152 acquires the current time as the inspection end time (step S108). The input control unit 152 acquires the current position information of the own device from the position information acquisition unit 14 (step S109). The input control unit 152 determines whether or not the own device is located within a predetermined allowable range from the inspection target facility based on the position information of the inspection target facility acquired in step S103 and the position information of the own device. (Step S110).

  When the own apparatus is not located within the predetermined allowable range from the facility to be inspected (step S110-NO), the input control unit 152 performs a display requesting the inspection operator to input secondary information (step S111). . The secondary information here refers to information obtained by another means that the inspection terminal 1 is located within the predetermined allowable range from the inspection target facility, or information used to explain the reason why the inspection terminal 1 is not within the predetermined allowable range. It is. What information is used as the secondary information may be arbitrarily determined, and the setting may be registered in the inspection terminal 1 in advance. For example, the secondary information may be a photographic image obtained by photographing the inspection target facility, or may be information obtained by reading a barcode attached to the inspection target facility. Further, the secondary information may be text information input by the inspection operator. By inputting such secondary information, for example, even if the location information of the equipment to be inspected or the inspection terminal 1 cannot be acquired for some reason, the inspection result can be handled as an effective inspection result. Become.

  The input control unit 152 determines whether secondary information has been input (step S112). When secondary information is not input (step S112 -NO), the input control part 152 returns a process to step S104, and makes an inspection operator input an inspection result again. On the other hand, when secondary information is input (step S112—YES), the input control unit 152 refers to the time required for inspection (hereinafter referred to as “required inspection time”) based on the inspection start time and the inspection end time. ) Is within a predetermined allowable range (step S113).

  When the required inspection time is not within the predetermined allowable range (step S113—NO), the input control unit 152 performs a display requesting the inspection operator to input secondary information (step S114). The secondary information here is information used for explaining the reason why the time required for inspection does not fall within a predetermined allowable range. For example, the secondary information may be text information input by an inspection worker. By inputting such secondary information, for example, even if the inspection work takes a long time for some reason, the inspection result can be handled as an effective inspection result.

  The input control unit 152 determines whether secondary information has been input (step S115). When secondary information is not input (step S115-NO), the input control part 152 returns a process to step S104, and makes an inspection operator input an inspection result again. On the other hand, when the secondary information is input (step S115—YES), the input control unit 152 determines whether there is an indispensable item in which the inspection result is not input in the pre-confirmation information (step S116). It is assumed that which items are set as essential items is set in the inspection terminal 1 in advance.

  When there is an indispensable item for which the inspection result has not been input (step S116: YES), the input control unit 152 returns the process to step S104, and causes the inspection operator to input the inspection result again. On the other hand, when the inspection result is input to all the essential items (step S116—NO), the input control unit 152 determines the pre-confirmation information as the inspection information and transmits it to the management server 2 (step S117).

  FIG. 9 is a flowchart illustrating a specific example of the input determination process. The flowchart shown in FIG. 9 is executed when the inspection result of each inspection item is input to the input screen. In the input determination process, input information of inspection results for the input screen is input.

  First, the input determination unit 153 acquires input information of an inspection item (hereinafter referred to as “target item”) that is a processing target (step S201). The input determination unit 153 acquires information (hereinafter referred to as “reference information”) that is a criterion for determining validity of the input information from the management server 2 (step S202). For example, the input determination unit 153 acquires the previous inspection information of the inspection target facility as reference information.

  The input determination unit 153 determines the validity of the input information by comparing the input information input on the input screen with the reference information acquired from the management server 2. Here, for example, a case where an inspection result of a certain inspection item is input as a numerical value will be described as an example. The input determination unit 153 determines whether a numerical value indicated by the input information (hereinafter referred to as “input value”) is within an allowable range with respect to a numerical value indicated by the reference information (hereinafter referred to as “reference value”). judge. For example, the input determination unit 153 determines whether or not the difference between the input value and the reference value is equal to or less than a predetermined threshold (step S203).

  When the difference between the input value and the reference value is equal to or smaller than the threshold value (step S203—YES), the input determination unit 153 sets the input value as a final value (step S204). On the other hand, when the difference between the input value and the reference value is larger than the threshold value (step S203—NO), the input determination unit 153 causes the display unit 12 to display a notification for confirming the input value (step S205). In response to this display, the input person inputs information indicating the validity of the current input value (hereinafter referred to as “determination information”).

  The input determination unit 153 determines whether the current input value is a correct value based on the input determination information (step S206). When the determination information indicates that the current input value is a correct value (step S206—YES), the process proceeds to step S204, and the input determination unit 153 sets the current input value as a final value. On the other hand, when the determination information indicates that the current input value is not correct (step S206—NO), the input determination unit 153 initializes the input field of the target item (step S207) and ends the input determination process. To do.

  The above-described determination information may simply be information indicating determination of validity of the input value (for example, “YES” or “NO”) by the input person (inspection worker). Further, for example, it may be represented by an input value that the input person inputs again upon receiving a confirmation notification for the current input value. For example, the input determination unit 153 may determine the input value when the same value as the previous input value is input as the determination information.

  The high-pressure gas equipment management system 10 according to the first embodiment configured as described above has the inspection terminal 1 provided with the inspection information transmission unit 154 that determines the effectiveness of the inspection result according to the position of the own apparatus, thereby performing the inspection work. It is possible to prevent a person from inspecting a wrong inspection target facility.

  In addition, the high pressure gas equipment management system 10 of the first embodiment has the inspection terminal 1 including the input determination unit 153 that determines the input information based on the determination of the validity of the input information of each inspection result. Accurate inspection information can be acquired.

  In addition, the high pressure gas equipment management system 10 of the first embodiment includes an inspection information transmission unit 154 that determines the effectiveness of inspection of the inspection target equipment based on the inspection time required for inputting the inspection result. The reliability of inspection information can be improved.

  The high-pressure gas facility management system 10 of the first embodiment has the above-described functions, so that the gas supplier can collect inspection information more appropriately. As a result, the operation load related to the supply and demand of high-pressure gas is reduced. It becomes possible to make it.

<Modification>
In the above embodiment, the flow of the input determination process has been described by taking the case where the inspection result is input as a numerical value, but the target of the input determination process is not necessarily limited to the input information input as a numerical value. For example, the input information to be subjected to the input determination process may be information indicating a sentence, information indicating an image, or the like. For example, when the inspection result is input as a sentence, the input determination unit 153 may determine the validity of the input information based on whether or not a predetermined keyword is included in the input information. When the inspection result is input as an image, the input determination unit 153 determines the validity of the input information based on the image feature amount acquired in the previous inspection and the image feature amount indicated by the input information. You may judge. As described above, as long as the validity of the input information can be determined by any method, the target of the input determination process may be any information. The determination of the validity of the input information may be realized by any method. For example, when the inspection result is input as a numerical value, the validity may be determined not by the difference between the input value and the reference value but by the ratio of the input value to the reference value (that is, the change rate).

  Moreover, in the said embodiment, although the reference value used for determination of the validity of an input value was made into the value which the last inspection information shows, a reference value is not limited to the value which the last inspection information shows. For example, the reference value may be a value acquired based on a past inspection result of the inspection target facility. For example, the reference value may be an average value of values indicated by past inspection results, or a statistical value such as a maximum value or a minimum value.

  In the above embodiment, the input determination unit 153 acquires the inspection target position information from the management server 2, but the acquisition of the inspection target position information is not limited to the method of acquiring from the management server 2. For example, the position information of all the inspection target facilities may be stored in advance in each inspection terminal 1. Further, the input determination unit 153 may acquire the inspection target position information by communicating with each inspection target facility. In this case, for example, each inspection target facility includes an IC tag that stores position information of the own facility, and the inspection terminal 1 includes an IC tag reader. The inspection terminal 1 may be configured to acquire inspection target position information from an IC tag of each inspection target facility by an IC tag reader.

Second Embodiment
As described above, the gas consumer needs to periodically check the high-pressure gas equipment that he / she operates. The gas consumer must grasp the remaining amount of the high-pressure gas through this periodic inspection, and operate the high-pressure gas equipment so that the gas can be stably supplied to the gas demand. Specifically, the gas consumer needs to order high-pressure gas from the gas supplier at an appropriate timing with respect to the remaining amount of high-pressure gas.

  FIG. 10 is a diagram showing an outline of gas ordering based on the inspection information. For example, the gas consumer has an ordering terminal 5 that can be connected to the management server 2 via the office LAN 3 and an ordering system 6 that performs an ordering process for the gas to the gas supplier. The ordering system 6 can communicate with an order receiving system 8 on the gas supplier side, for example, via the Internet 7. The person in charge of ordering on the gas consumer side obtains inspection information from the management server 2 using the ordering terminal 5 and periodically checks the remaining amount of high-pressure gas in each high-pressure gas facility. When the person in charge of ordering confirms the high-pressure gas equipment that needs to be replenished with high-pressure gas, the ordering person inputs an ordering instruction for the required amount of high-pressure gas to the ordering system 6.

  The ordering system 6 generates ordering information for ordering high-pressure gas from the ordering system 8 based on the ordering instruction input from the ordering terminal 5. The ordering system 6 orders the necessary amount of high-pressure gas from the gas supplier by transmitting the generated ordering information to the ordering system 8 on the gas supplier side via the Internet 7. The order receiving system 8 receives the ordering information transmitted from the ordering system 6 to receive an order for high-pressure gas from the gas consumer. When the gas supplier receives an order for high-pressure gas from the gas consumer, the gas supplier delivers the amount of high-pressure gas indicated by the ordering information to the gas consumer.

  Conventionally, the gas consumer side has inspected and ordered high-pressure gas equipment based on such inspection information. However, in such equipment management, the gas consumer side requires high-pressure gas according to the remaining amount of gas. A person in charge of ordering is required. Since the usage status of the high-pressure gas may vary depending on the application of the high-pressure gas, the person in charge of ordering needs to confirm the high-pressure gas at an appropriate timing with which the high-pressure gas is not exhausted. Furthermore, there is a possibility that temporary mass consumption may occur in the usage state of high-pressure gas. When it is assumed that there is such a sudden change in the usage situation, the person in charge of ordering needs to check the remaining amount of gas at sufficiently short intervals, which is a heavy burden on the gas consumer. Therefore, in order to stably supply the high-pressure gas, it is necessary to place an order for the high-pressure gas at an appropriate timing in accordance with such a sudden change in the usage situation. For this reason, the high pressure gas equipment management system according to the second embodiment has a function of automatically instructing ordering of high pressure gas to the ordering system 6 according to the remaining amount of gas.

  FIG. 11 is a schematic diagram illustrating a configuration example of the high-pressure gas equipment management system 10a according to the second embodiment. The high-pressure gas equipment management system 10a is different from the high-pressure gas equipment management system 10 of the first embodiment in that a liquid level sensor 20 is provided instead of the inspection terminal 1 and a management server 2a is provided instead of the management server 2. The liquid level sensor 20 is a sensor that measures the position (hereinafter referred to as “liquid level value”) of the liquid level in a high-pressure gas facility (for example, a low temperature liquefied gas storage tank). The liquid level sensor 20 acquires the liquid level value of the high-pressure gas equipment, and is provided in any manner as long as the acquired liquid level value information (hereinafter referred to as “liquid level value information”) can be communicated to the outside. May be. For example, in the present embodiment, the liquid level sensor 20 transmits the liquid level value information to the management server 2a via the mobile communication network 4 as with the inspection terminal 1. The management server 2a has a function of performing demand prediction of high-pressure gas based on the liquid level value information transmitted from the liquid level sensor 20, and giving an ordering instruction corresponding to the demand prediction to the ordering system 6.

  FIG. 12 is a functional block diagram showing a functional configuration of the management server 2a in the high-pressure gas equipment management system 10a of the second embodiment. The management server 2a does not include the inspection information acquisition unit 23 and the inspection information provision unit 24, and further includes a liquid level information acquisition unit 25, a demand prediction unit 26, and an automatic ordering unit 27, according to the first embodiment. Different from 2.

  The liquid level information acquisition unit 25 acquires liquid level value information from the liquid level sensor 20 via the communication unit 21. The liquid level information is transmitted from the liquid level sensor 20 at every predetermined timing (for example, every hour). The liquid level information acquisition unit 25 stores the acquired liquid level value information in the storage unit 22. Specifically, information in which the liquid level value is associated with the time when the liquid level value is measured is stored in the storage unit 22 as liquid level value information.

  The demand prediction unit 26 calculates the remaining amount of the high-pressure gas remaining in the high-pressure gas facility based on the liquid level information stored in the storage unit 22, and the demand for the high-pressure gas based on the calculated remaining gas amount. Make a prediction. For example, when the liquid level sensor 20 is based on a differential pressure type measurement method, the demand prediction unit 26 converts the pressure difference between the gas phase part and the liquid phase part into a liquid depth to convert the high pressure in the high pressure gas equipment. Calculate the remaining amount of gas. The demand prediction unit 26 calculates the remaining amount of high-pressure gas each time the liquid level information is acquired, and compares the calculated remaining gas amount with a preset threshold value α of the remaining gas amount, thereby demanding the high-pressure gas. Make a prediction. Specifically, the demand prediction unit 26 notifies the automatic ordering unit 27 that the high-pressure gas needs to be replenished when the remaining gas amount falls below the threshold value α. Hereinafter, this notification is referred to as an order required notification.

  The management server 2a includes identification information (hereinafter referred to as “sensor ID”) of each liquid level sensor 20 and attribute information (for example, an upper limit storage amount) of the high-pressure gas facility in which the liquid level sensor 20 is installed. Correspondence information indicating the correspondence relationship is stored in the storage unit 22 in advance. Further, the liquid level information includes a sensor ID, and the demand prediction unit 26 obtains the high pressure from which the liquid level value information has been acquired based on the sensor ID and the correspondence information indicated by the acquired liquid level value information. The attribute information of the gas equipment can be acquired. The demand prediction unit 26 calculates an approximate replenishment amount of the high-pressure gas necessary for the high-pressure gas facility from which the liquid level information is acquired, from the difference between the upper limit storage amount and the remaining gas amount. The demand forecasting unit 26 notifies the automatic ordering unit 27 of a required order notification including the identification information of the high-pressure gas facility to be replenished and the replenishment amount of the high-pressure gas necessary for the high-pressure gas facility.

  The automatic ordering unit 27 generates high-pressure gas ordering information related to the notified high-pressure gas facility in response to the order-needed notification notified from the demand prediction unit 26. The automatic ordering unit 27 sends the generated ordering information to the ordering system 6 to instruct the ordering of a required amount of high-pressure gas to the ordering system 8 on the gas supplier side.

  The high pressure gas equipment management system 10a of the second embodiment configured as described above performs the demand prediction of the high pressure gas based on the liquid level value measured by the liquid level sensor 20, and the amount of the high pressure according to the demand prediction. A management server 2a for instructing gas ordering is provided. By providing such a configuration, the gas supplier can supply high-pressure gas to the gas consumer at an appropriate timing, and the operational load on the gas consumer can be reduced.

  A part or all of the high-pressure gas equipment management system 10 in the above-described embodiment may be realized by a computer. In that case, a program for realizing this function may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be read into a computer system and executed. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory inside a computer system serving as a server or a client in that case may be included and a program held for a certain period of time. Further, the program may be a program for realizing a part of the above-described functions, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system. You may implement | achieve using programmable logic devices, such as FPGA (Field Programmable Gate Array).

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes designs and the like that do not depart from the gist of the present invention.
