[0011] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this embodiment, a line and an energy storage system are assumed as examples of equipment or facilities for which a maintenance management contract is concluded. However, this embodiment is applicable to any equipment or facilities for which a maintenance management contract is concluded in connection with maintenance services for the equipment or facilities, and is not limited to the equipment or facilities illustrated above.

[0012] FIG. 1 is a diagram showing the overall configuration of a quality monitoring system 1000 according to this embodiment. The quality monitoring system 1000 includes a calculation server 110 and a data collection server 120, and is capable of communicating with information reference and control terminals 140a to 140c. The quality monitoring system 1000 monitors the operating quality of equipment while maintaining transparency in the disclaimer agreement process.

[0013] The facility 130 is a target whose quality is monitored by the quality monitoring system 1000, and is, for example, a line or an energy storage system. In this embodiment, a contract is concluded between the service contract provider and the contractor to maintain the facility 130 over the long term and guarantee its quality. The data collection server 120 collects an operation log 2120 from the facility 130 via the network 170. The facility 130 is configured to include a plurality of parts.

[0014] The calculation server 110 includes a network interface 113 , a storage device 111 , an arithmetic unit 112 , and a memory 114 . The network interface 113 transmits and receives data to and from external servers and terminals via the network 160 .

[0015] The storage device 111 stores the quality monitoring program 220 (see FIG. 2) of this embodiment, data received from an external server or terminal, and data output by execution of the quality monitoring program 220. The arithmetic device 112 reads the quality monitoring program 220 and data required for processing from the storage device 111 into the memory 114, and executes this quality monitoring program 220. The calculation server 110 receives the operation log 2120, and transmits a quality calculation result 2130 and a quality report 2131 to the information reference and control terminals 140a to 140c.

[0016] The information reference and control terminals 140 a to 140 c each include a computing device 144 , a network interface 141 , an input device 142 , and a display device 143 . The arithmetic device 112 loads programs and data (not shown) required for processing from a storage device (not shown) into memory and executes the programs to centrally control the information reference and control terminals 140a to 140c. The network interface 141 transmits and receives various data to and from the calculation server 110 via the network 160. The input device 142 is, for example, a touch panel, mouse, keyboard, etc., and is used by users to input contract details, agreement results, etc. The display device 143 is, for example, an LCD display, etc., and displays quality monitoring results and quality reports to users. The user refers to the service contract provider or the contractor.

[0017] The arithmetic units 144 of the information reference and control terminals 140a to 140c receive the quality calculation result 2130 and the quality report 2131 from the calculation server 110 and display them on the display device 143. Then, the arithmetic units 144 of the information reference and control terminals 140a to 140c transmit the contract details 2110 input from the input device 142 to the calculation server 110 via the network interface 141. The arithmetic units 144 transmit and receive the agreement result 2111 to and from each other via the calculation server 110.

[0018] On the contract provider side, there is an operations manager who is responsible for operating the maintenance service, and a field worker who actually performs the maintenance work. The operations manager who is responsible for operating the maintenance service uses the information reference and control terminal 140a. The field worker who actually performs the maintenance work uses the information reference and control terminal 140b. On the contracting party side, the customer's representative uses the information reference and control terminal 140c.

[0019] FIG. 2 is a functional block diagram of the quality monitoring system 1000. The storage device 111 in the calculation server 110 stores a database 210 and a quality monitoring program 220. The database 210 stores an operation log database 212, a contract content database 211, a quality calculation result database 213, and a fault log database 214. The data of the various databases stored in the database 210 may be stored in a distributed ledger on a blockchain.

[0020] The contract content database 211 stores contract content 2110 input from the input unit 241 in the information reference / control terminal 140a, 140c. An example of the contract content 2110 is shown in FIG. The operation log database 212 stores an operation log 2120 sent from the data collection unit 231 in the data collection server 120. An example of the operation log 2120 is shown in FIG.

[0021] The quality calculation result database 213 stores quality calculation results 2130 calculated by processing by the quality monitoring program 220. An example of the quality calculation result 2130 is shown in FIG. The fault log database 214 stores a fault log 2140 input from the input unit 241 of any one of the information reference and control terminals 140a to 140c. An example of the fault log 2140 is shown in FIG.

[0022] The quality monitoring program 220 is a program for monitoring the quality of the facility 130. When the arithmetic device 112 in Fig. 1 executes the quality monitoring program 220, a quality calculation unit 221, a disclaimer sequential agreement unit 222, a quality visualization unit 223, and a quality report unit 224 are realized.

[0023] The quality calculation unit 221 calculates a quality calculation result 2130 of the equipment 130 from the operation log database 212 in accordance with the quality definition described in the contract details 2110 of the contract details database 211. The quality calculation unit 221 saves the calculated quality calculation result 2130 in the quality calculation result database 213. The quality calculation unit 221 calculates the availability rate, which is defined as the number of parts in operation relative to the total number of predetermined parts that make up the equipment 130, as the quality. Here, the equipment 130 receives maintenance service based on a contract that guarantees quality and includes a disclaimer.

[0024] If the operation quality of the facility 130 falls outside the normal range predefined in the contract, the disclaimer sequential agreement unit 222 regards this quality degradation as a fault. If the operation quality of the facility 130 has deteriorated, the disclaimer sequential agreement unit 222 processes communication with the user regarding the fault, and if it recalculates the fault log 2140 or the quality calculation result 2130, it stores the quality calculation result 2130 in the quality calculation result database 213. In this way, the disclaimer sequential agreement unit 222 allows the provider of the maintenance service for the facility 130 and the contractor to sequentially agree on whether or not this quality degradation is due to a disclaimer in the contract.

[0025] Interactions with users regarding the failure include receiving input of instructions to investigate the cause of the failure through the input unit 241 in the information reference / control terminal 140, receiving input of the results of the investigation into the cause of the failure, and receiving input of the agreement on whether the failure is due to a disclaimer.

[0026] Furthermore, communication with the user regarding the failure includes displaying a notification of the quality degradation and displaying the results of an investigation into the cause of the failure via the display unit 242 in the information reference / control terminal 140. The quality visualization unit 223 visualizes information indicating the operating quality of the equipment 130 in tables and graphs from the quality calculation results 2130 and the failure log 2140.

[0027] The quality report unit 224 creates and outputs a quality report for a predetermined period based on the quality target value described in the contract, the quality calculation result 2130, and the fault log 2140. Examples of the quality report created by the quality report unit 224 are shown in Figures 16 to 19. The data collection unit 231 in the data collection server 120 collects the operation log 2120 from the equipment 130 and transmits it to the calculation server 110.

[0028] The input unit 241 in the information reference / control terminal 140 accepts inputs from the user of the contract details, instructions to investigate the cause of the failure, the results of the investigation into the cause of the failure, and the agreement result regarding whether the failure is due to a disclaimer. The display unit 242 displays to the user the notification of quality degradation, the results of the investigation into the cause of the failure, tables and data showing quality, and quality reports sent from the calculation server 110 to the information reference / control terminal 140.

[0029] FIG. 3 is a diagram showing an example of the contract details 2110. The contract details 2110 include a quality definition 310, a disclaimer definition 320, and facility information 330. The quality definition 310 is a definition of the quality monitored by the system according to the present invention, and includes the type of quality, a calculation formula, a normal range, and a target value. The type of quality may be, for example, the availability of the facility 130, the communication speed in the case of a line provision service, or the battery charge capacity in the case of an energy storage system. Here, the availability is the ratio of the number of operating parts to the total number of predetermined parts in a facility or device consisting of multiple parts (components). The normal range is the range of quality values ​​within which the quality is not considered to have deteriorated.

[0030] If the quality calculation result is outside the normal range, the disclaimer sequential agreement unit 222 notifies the user that the quality has deteriorated. The disclaimer definition 320 is a definition of the disclaimer, and includes the name and details of the disclaimer. Examples of disclaimers include failure due to disaster and loss due to theft. The equipment information 330 represents the specifications necessary for calculating the quality of the equipment 130 that is the monitoring target of the present invention. For example, if the availability rate of the equipment 130 is monitored as the quality, the equipment information 330 includes the total number of each part.

[0031] FIG. 4 is a diagram showing an example of the operation log 2120. The operation log 2120 is log data when the equipment 130 monitored by the quality monitoring system 1000 is operating, and includes the time when the data was acquired and information necessary for calculating the quality of the equipment 130. The information necessary for calculating the quality of the equipment 130 includes values ​​from sensors (not shown) installed in the equipment 130, the number of parts currently in operation within the equipment 130, etc.

[0032] FIG. 5 is a diagram showing an example of the quality calculation result 2130. The quality calculation result 2130 is data indicating the quality calculated by the quality calculation unit 221. Each row in Fig. 5 represents a record of data acquired at a particular time. Each record includes the following items: the time when the data used in the quality calculation was acquired, the calculated value of the quality, the calculated value of the agreed-upon quality, the number of faults, the number of agreed-upon faults, and the fault log ID.

[0033] The calculated quality value is a value calculated from the operation log 2120 in accordance with the quality definition included in the contract details, and is a value that does not take into account whether or not the failure is due to a disclaimer, even if a quality degradation has occurred in the record. On the other hand, the calculated agreed quality value is a value that takes into account whether or not the quality degradation in the record is due to a disclaimer. For records where no quality degradation has occurred, the calculated quality value and the calculated agreed quality value are the same. The number of failures is the total number of failures (quality degradation) that occurred in the record, and is the sum of the number of agreed-upon failures and the number of failures that have not yet been agreed upon. If the number of failures and the number of agreed-upon failures are the same, the contract provider and the contractor have agreed on whether or not the quality degradation in the record is due to a disclaimer, and the quality calculation result for the record will not change thereafter. Note that for records where quality has not degraded, the number of failures occurred and the number of agreed-upon failures are set to 0. The failure log ID is the ID of the failure log that contains detailed investigation results into the cause of the failure in the record.

[0034] FIG. 6 is a diagram showing an example of the error log 2140. The fault log 2140 is configured to include fault information 610 and an investigation log 620. The fault information 610 is information related to quality degradation (failure). Each row of the fault information 610 is a record that constitutes the fault information 610. Each record includes items such as an ID, the time when the quality degradation occurred, a status regarding whether an agreement has been reached regarding whether the quality degradation is due to a disclaimer, the details of the fault, and the final agreement result regarding whether the quality degradation is due to a disclaimer. The status is either pending or agreed upon.

[0035] The investigation log 620 is a record of user actions related to quality degradation. Each line of the investigation log 620 is a record that constitutes the investigation log 620. Each record records a detailed investigation into the cause of the quality degradation, the measures taken to address the quality degradation, and the user's judgment as to whether the quality degradation was due to a disclaimer. The investigation log 620 includes the time when the action indicated by the record was performed, the person who conducted the investigation or action and created the record, and the details of the investigation and the measures taken.

[0036] FIG. 7 is a diagram showing the data structure on the blockchain. Block 710a is the k-th block and includes a hash value 711a related to the immediately preceding block and data 712a including multiple records of the quality calculation result 2130.

[0037] Block 710b is the (k+1)th block and includes a hash value 711b related to the immediately preceding block 710a, and data 712b including multiple records of the quality calculation result 2130.

[0038] Data 712a is a set of records updated during a predetermined period, and data 712b is a set of records updated during a predetermined period following the predetermined period during which data 712a was updated. 7 shows an example of the quality calculation result. Hash value 711b is a value calculated by inputting block 710a into a hash function. In this way, by managing the quality calculation result 2130 in a blockchain at predetermined intervals, data tampering can be prevented.

[0039] The contract details 2110 shown in Figure 3, the operation log 2120 shown in Figure 4, and the fault log 2140 shown in Figure 6 may be stored on a blockchain as shown in Figure 7, or may be stored in a tabular relational database as shown in Figures 3 to 6, and are not limited to this.

[0040] Fig. 8 is a flowchart of the quality monitoring process. The operation based on the flowchart in Fig. 8 is as follows. The calculation server 110 receives the operation log 2120 from the data collection server 120 (step 801). This process is performed at predetermined intervals, such as every hour or every 24 hours. The calculation server 110 stores the received operation log 2120 in the operation log database 212 (step 802).

[0041] The quality calculation unit 221 acquires the contract details 2110 from the contract details database 211 and the operation log 2120 from the operation log database 212, calculates the quality to be monitored using the equipment information 330 and the operation log 2120 in accordance with the quality definition 310, and generates the quality calculation result 2130 (step 803). At this point, no processing related to quality degradation has been performed, but the same value as the calculated value of the agreed quality is stored. Also, because processing related to quality degradation has not been performed, the number of failures is not recorded.

[0042] The quality calculation unit 221 checks whether each record of the quality calculation result 2130, which is a calculated value of quality, is outside the normal range described in the quality definition 310 (step S804). If the calculated quality value is within the normal range (No), the quality has not deteriorated, so the quality calculation unit 221 does not perform any processing related to the deterioration of quality and proceeds to step 809. If the calculated quality value is outside the normal range (Yes), the quality calculation unit 221 increments the number of faults for the record in the quality calculation result 2130 by one.

[0043] The disclaimer sequential agreement unit 222 performs the disclaimer sequential agreement process shown in the flowchart of Fig. 9 (step 805). Then, the disclaimer sequential agreement unit 222 determines whether it has been agreed that the quality degradation is not due to the disclaimer (step 806). If it has been agreed that the quality degradation is due to the disclaimer (Yes), the disclaimer sequential agreement unit 222 proceeds to step 807. If it has been agreed that the quality degradation is not due to the disclaimer (No), the disclaimer sequential agreement unit 222 proceeds to step 809 without performing a process to correct the calculated value of the agreed-upon quality.

[0044] In step 807, the quality calculation unit 221 obtains the contract details 2110 from the contract details database 211, the operation log 2120 from the operation log database 212, and the failure log 2140 from the failure log database 214. Next, the quality calculation unit 221 checks the failure log 2140, excludes the agreed-upon failure as not occurring according to the disclaimer, and recalculates the quality to be monitored using the equipment information and operation log 2120 in accordance with the quality definition (step 808). Here, the quality calculation unit 221 stores the recalculated quality in the calculated value of the agreed-upon quality for the corresponding record in the quality calculation result 2130. Furthermore, because the failure has been agreed upon, the quality calculation unit 221 increments the number of agreed-upon failures for the corresponding record in the quality calculation result 2130 by 1.

[0045] In step 809, the quality calculation unit 221 calculates the hash value of the previous block. Next, the quality calculation unit 221 stores the calculated hash value and the quality calculation result 2130 to be saved as one block in the quality calculation result database 213 (step 810), and ends the processing in FIG. The quality calculation unit 221 may simply store the quality calculation result 2130 in the quality calculation result database 213 without using a blockchain.

[0046] The quality visualization unit 223 performs processing every time the quality calculation result 2130 or the fault log 2140 is updated. The quality visualization unit 223 obtains the quality calculation result 2130 from the quality calculation result database 213 and the fault log 2140 from the fault log database 214, generates screens such as those shown in Fig. 10 and Fig. 11, and outputs them to the display unit 242 in the information reference / control terminal 140.

[0047] The quality report unit 224 performs processing, for example, when a user requests a quality report through the input unit 241. The quality report unit 224 obtains the contract content 2110 (including the target value of the quality of the quality definition) from the contract content database 211, the quality calculation result 2130 from the quality calculation result database 213, and the failure log 2140 from the failure log database 214, generates screens such as those shown in Figures 16, 17, 18, and 19, and displays them on the display unit 242 in the information reference / control terminal 140.

[0048] FIG. 9 is a flowchart of the disclaimer agreement process. In step 804 of FIG. 8, the quality calculation unit 221 determines whether the calculated quality value is outside the normal range of quality within the quality definition, and if the quality has decreased, the disclaimer sequential agreement unit 222 proceeds to step S805 and executes processing according to the flowchart of FIG. 9.

[0049] The disclaimer sequential agreement unit 222 creates fault information (step 901) and stores it in the fault log database 214. The disclaimer sequential agreement unit 222 also transmits a notification of quality degradation to the information reference and control terminal 140a of the operations manager (step 902). The arithmetic unit 144 of the information reference and control terminal 140a of the operator displays a notice of quality degradation on the display unit 242 (step 903).

[0050] Furthermore, the arithmetic unit 144 of the operations manager's information reference and control terminal 140a requests data from the disclaimer sequential agreement unit 222 via the input unit 241 to enable the operations manager to determine whether or not the degradation in quality is due to a disclaimer. Data for determining whether or not the degradation in quality is due to a disclaimer is, for example, the operation log 2120, the quality calculation result 2130, or the failure log 2140. The disclaimer sequential agreement unit 222 obtains the requested data from the database 210 and transmits it to the operations manager's information reference and control terminal 140a. The arithmetic unit 144 of the operations manager's information reference and control terminal 140a displays the received data as related information on the display unit 242 (step 904).

[0051] Furthermore, in order for the operations manager to determine whether the deterioration in quality is due to a disclaimer, the arithmetic unit 144 of the information reference / control terminal 140a accepts input via the input unit 241 as to whether or not additional investigation of the data is necessary (step 905).

[0052] In step 906, the information reference / control terminal 140a of the operations manager performs processing to confirm whether or not additional investigation is necessary. If the input indicates that additional investigation is unnecessary (No), the process proceeds to step 910. If the input indicates that additional investigation is necessary, the process proceeds to step 907.

[0053] In step 907, the arithmetic unit 144 of the information reference / control terminal 140a of the operations manager transmits a request for additional investigation to the exemption item sequential agreement unit 222. The exemption item sequential agreement unit 222 stores the request for additional investigation as an investigation log in the fault log database 214, and transmits a request for additional investigation regarding the quality degradation to the information reference / control terminal 140b of the field worker.

[0054] The arithmetic unit 144 of the on-site worker's information reference / control terminal 140b displays the received additional investigation instruction on the display unit 242 (step 908). The arithmetic unit 144 of the on-site worker's information reference / control terminal 140b accepts input of an investigation log related to the additional investigation through the input unit 241, and transmits the input investigation log to the exemption item sequential agreement unit 222 (step 909).
