Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the respective figures.
In this embodiment, a line and an energy storage system are assumed as examples of equipment or facilities to which a maintenance management contract is to be concluded. However, this embodiment is applicable as long as a maintenance management contract is concluded in conjunction with maintenance services for equipment or equipment, and is not limited to the exemplified equipment or equipment.

FIG. 1 is an overall configuration diagram of a quality monitoring system 1000 of 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/control terminals 140a to 140c. The quality monitoring system 1000 monitors the operating quality of equipment while maintaining transparency in the disclaimer agreement process.

The equipment 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 equipment 130 over a long period of time and guarantee its quality. Data collection server 120 collects operation logs 2120 from equipment 130 via network 170. Equipment 130 is configured to include a plurality of parts.

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

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 loads a quality monitoring program 220 and data necessary for processing from the storage device 111 into the memory 114, and executes the quality monitoring program 220.
The calculation server 110 receives the operation log 2120 and sends the quality calculation result 2130 and quality report 2131 to the information reference/control terminals 140a to 140c.

The information reference/control terminals 140a to 140c are configured to include a calculation 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) necessary for processing into a memory from a storage device (not shown) and executes the programs, thereby controlling the information reference/control terminals 140a to 140c in an integrated manner. The network interface 141 transmits and receives various data to and from the calculation server 110 through the network 160. The input device 142 is, for example, a touch panel, a mouse, a keyboard, etc., and is used by the user to input contract details, agreement results, and the like. The display device 143 is, for example, a liquid crystal display, and displays quality monitoring results and quality reports to the user. Note that the user refers to a service contract provider or contractor.

The computing device 144 of the information reference/control terminals 140a to 140c receives the quality calculation result 2130 and the quality report 2131 from the calculation server 110 and displays them on the display device 143. Then, the computing device 144 of the information reference/control terminals 140a to 140c transmits the contract details 2110 input from the input device 142 to the calculation server 110 via the network interface 141. The computing devices 144 mutually transmit and receive the agreement result 2111 via the computing server 110.

On the contract provider side, there is an operations manager who is responsible for operating the maintenance service, and field workers who actually carry out the maintenance work. An operations manager responsible for operating the maintenance service uses the information reference/control terminal 140a. A field worker who actually performs maintenance work uses the information reference/control terminal 140b. On the contracting party's side, the person in charge of the customer side uses the information reference/control terminal 140c.

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

The contract details database 211 stores the contract details 2110 input from the input section 241 in the information reference/control terminals 140a, 140c. An example of the contract details 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. 4, which will be described later.

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

The quality monitoring program 220 is a program for monitoring the quality of the equipment 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.

The quality calculation unit 221 calculates the quality calculation result 2130 of the equipment 130 from the operation log database 212 according to the quality definition described in the contract content 2110 of the contract content database 211. The quality calculation unit 221 stores the calculated quality calculation result 2130 in the quality calculation result database 213. The quality calculation unit 221 calculates the operation rate defined by the number of parts in operation relative to the total number of parts that are predetermined in advance among the parts constituting the equipment 130, and uses this as quality. Here, the equipment 130 receives maintenance services based on a contract that guarantees quality and includes disclaimers.

If the operating quality of the equipment 130 falls outside the normal range predefined in the contract, the disclaimer sequential agreement unit 222 considers this quality deterioration to be a failure. If the operational quality of the equipment 130 has deteriorated, the disclaimer sequential agreement unit 222 processes the communication with the user regarding the failure, and if the failure log 2140 or the quality calculation result 2130 is recalculated, the disclaimer sequential agreement unit 222 updates the quality calculation result 2130. The quality calculation results are saved in the database 213. Thereby, the disclaimer sequential agreement section 222 causes the maintenance service provider of the equipment 130 and the contractor to sequentially agree whether or not this quality reduction is due to the disclaimer of the contract.

Communication with users regarding failures includes accepting instructions to investigate the cause of the failure through the input unit 241 in the information reference/control terminal 140, inputting the results of an investigation into the cause of the failure, and whether or not the failure is due to a disclaimer. Includes input acceptance of agreement results regarding.

Furthermore, interactions with the user regarding the failure include displaying a notification of quality deterioration through the display unit 242 in the information reference/control terminal 140 and displaying the results of an investigation into the cause of the failure. The quality visualization unit 223 visualizes information indicating the operational quality of the equipment 130 from the quality calculation result 2130 and the failure log 2140 in a table and a graph.

The quality report unit 224 creates and outputs a quality report for a predetermined period from the quality target value stated in the contract details, the quality calculation result 2130, and the failure log 2140. Examples of quality reports created by the quality report unit 224 are shown in FIGS. 16 to 19. The data collection unit 231 in the data collection server 120 collects operation logs 2120 from the equipment 130 and sends them to the calculation server 110.

The input unit 241 in the information reference/control terminal 140 receives input from the user of the contract details, an instruction to investigate the cause of the failure, the results of the investigation into the cause of the failure, and the result of an agreement regarding whether or not the failure is due to a disclaimer. The display unit 242 displays to the user a notice of quality deterioration, an investigation result of the cause of the failure, a table or data representing quality, and a quality report sent from the calculation server 110 to the information reference/control terminal 140.

FIG. 3 is a diagram showing an example of contract details 2110.
The contract content 2110 includes a quality definition 310, a disclaimer definition 320, and equipment information 330. The quality definition 310 is a definition of quality monitored by the system according to the present invention, and includes quality type, calculation formula, normal range, and target value. The types of quality include, for example, the operating rate of the equipment 130, the communication speed in the case of a line provision service, and the charging capacity of the battery in the case of an energy storage system. Here, the operating rate is defined as the ratio of the number of parts in operation to the total number of predetermined parts in equipment or equipment consisting of a plurality of parts (components). The normal range is a range of quality values in which quality is not degraded.

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 a disclaimer, and includes the name and details of the disclaimer. Exemptions include, for example, malfunction due to disaster, loss due to theft, etc. The equipment information 330 represents specifications necessary for quality calculation of the equipment 130 that is a monitoring target of the present invention. For example, when monitoring the operating rate of the equipment 130 as quality, the equipment information 330 includes the total number of each part.

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 in operation, and includes the time when the data was acquired and information necessary for calculating the quality of the equipment 130. Information necessary for calculating the quality of the equipment 130 includes the values of sensors (not shown) installed in the equipment 130, the number of parts in operation in the equipment 130, and the like.

FIG. 5 is a diagram showing an example of the quality calculation result 2130.
The quality calculation result 2130 is data representing the quality calculated by the quality calculation unit 221. Each row in FIG. 5 has data acquired at each time as each record. Each record includes the following items: time when the data used for quality calculation was obtained, calculated quality value, agreed calculated quality value, number of failures, number of agreed failures, and failure log ID. configured.

The calculated value of quality is a value calculated from the operation log 2120 according to the quality definition included in the contract contents, and is a value that does not take into account whether or not the failure is due to a disclaimer even if quality deterioration occurs in the record. On the other hand, the agreed-upon calculated value of quality is a value that takes into consideration whether or not the quality deterioration in the record is due to a disclaimer. For records without quality degradation, the calculated quality value and the agreed-upon calculated quality value will be the same value. The number of failures is the total number of failures (quality deterioration) that have occurred in the record, and is the sum of the number of failures that have been agreed upon and the number of failures that have not yet been agreed upon. If the number of failures and the number of agreed failures are the same value, the contract provider and the contractor have agreed whether or not the quality degradation of the record is due to the disclaimer, and the quality calculation result of the record does not change thereafter. Note that for records in which the quality has not deteriorated, the number of failure occurrences and the number of agreed failures are set to zero. The failure log ID is an ID of a failure log in which detailed investigation results of the cause of the failure of the record are written.

FIG. 6 is a diagram showing an example of the failure log 2140.
The failure log 2140 includes failure information 610 and investigation log 620. Failure information 610 is information regarding quality deterioration (failure). Each row of the fault information 610 is a record that constitutes the fault information 610. Each record includes the following items: ID, time when the quality degradation occurred, status regarding whether or not it has been agreed whether or not the quality degradation is due to the disclaimer, failure details, and final agreement result regarding whether or not the quality degradation is due to the disclaimer. include. The status is pending or agreed.

The investigation log 620 is a record of user behavior regarding quality deterioration. Each line of the investigation log 620 is a record that constitutes the investigation log 620. Each record includes a detailed investigation into the cause of the quality decline, details of the measures taken to address the quality decline, and the user's judgment as to whether the quality decline was due to a disclaimer. The investigation log 620 includes the time when the action indicated by the record was performed, the person who created the record by conducting the investigation and countermeasures, and the details of the investigation and countermeasures.

FIG. 7 is a diagram showing the data structure on the blockchain.
Block 710a is the kth block. The block 710a includes a hash value 711a related to the immediately previous block and data 712a including a plurality of records of the quality calculation results 2130.

Block 710b is the k+1st block. The block 710b includes a hash value 711b related to the immediately preceding block 710a, and data 712b including a plurality of records of the quality calculation results 2130.

Data 712a is a set of records updated in a predetermined period. Data 712b is a set of records updated in a predetermined period following the predetermined period in which data 712a was updated.
FIG. 7 is an example in which the data is a quality calculation result. The hash value 711b is a value calculated by inputting the block 710a to a hash function. In this way, by managing the quality calculation results 2130 on the blockchain every predetermined period, data falsification can be prevented.

The contract details 2110 shown in FIG. 3, the operation log 2120 shown in FIG. 4, and the failure log 2140 shown in FIG. 6 may be stored on a blockchain as shown in FIG. It may be stored in a tabular relational database as shown, but is not limited thereto.

FIG. 8 is a flowchart of quality monitoring processing. The operation based on the flowchart of 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 operation log 2120 received by the calculation server 110 is stored in the operation log database 212 (step 802).

The quality calculation unit 221 acquires the contract contents 2110 from the contract contents 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 according to the quality definition 310, and calculates the quality. A calculation result 2130 is generated (step 803). At this point, no processing related to quality deterioration is performed, but the same value as the agreed quality calculation value is stored. Furthermore, the number of failures is not recorded because the processing related to quality deterioration has not been performed.

The quality calculation unit 221 checks whether each record of the quality calculation result 2130, which is a calculated quality value, is outside the normal range described in the quality definition 310 (step S804).
If the calculated value of quality is within the normal range (No), the quality calculation unit 221 does not perform any process related to quality degradation because the quality has not deteriorated, and the process proceeds to step 809. If the calculated quality value is outside the normal range (Yes), the quality calculation unit 221 increases the number of failures of the record in the quality calculation result 2130 by one.

The disclaimer sequential agreement unit 222 performs disclaimer sequential agreement processing shown in the flowchart of FIG. 9 (step 805). Then, the disclaimer sequential agreement unit 222 determines whether it is agreed that the quality reduction is not due to the disclaimer (step 806). If it is agreed that the quality degradation is based on the disclaimer (Yes), the process proceeds to step 807. If it is agreed that the quality reduction is not due to the disclaimer (No), the disclaimer sequential agreement unit 222 does not perform the process of correcting the agreed calculated quality value, and the process proceeds to step 809.

At 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 failure according to the disclaimer as having not occurred, and adjusts the quality to be monitored using the equipment information and operation log 2120 according to the quality definition. Recalculate (step 808). Here, the quality calculation unit 221 stores the recalculated quality in the calculated value of the agreed quality of the record in the quality calculation result 2130. Furthermore, since the failures have been agreed upon, the quality calculation unit 221 increases the number of agreed failures of the record in the quality calculation result 2130 by one.

At 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 stored as one block in the quality calculation result database 213 (step 810), and the process of FIG. 8 ends.
Note that the quality calculation unit 221 may simply store the quality calculation result 2130 in the quality calculation result database 213 without using the blockchain.

The processing by the quality visualization unit 223 is performed every time the quality calculation result 2130 or the failure log 2140 is updated. The processing by the quality visualization unit 223 acquires 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 as shown in FIGS. 10 and 11, and performs information reference and control. This is a process of outputting to the display unit 242 in the terminal 140.

Furthermore, the processing by the quality report unit 224 is performed, for example, when a user requests a quality report through the input unit 241. The quality report unit 224 processes the contract details 2110 (including the quality target value of the quality definition) from the contract details database 211, the quality calculation results 2130 from the quality calculation results database 213, and the failure log 2140 from the failure log database 214. This is a process of acquiring information, generating screens as shown in FIGS. 16, 17, 18, and 19, and displaying the screens on the display section 242 in the information reference/control terminal 140.

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 deteriorated, the disclaimer sequential agreement unit 222 proceeds to step S805 and executes the process according to the flowchart of FIG.

The disclaimer sequential agreement unit 222 creates failure information (step 901) and stores it in the failure log database 214. Further, the disclaimer sequential agreement section 222 transmits a notice of quality deterioration to the information reference/control terminal 140a of the operation manager (step 902).
The computing device 144 of the information reference/control terminal 140a of the operation manager displays a notification of quality deterioration on the display unit 242 (step 903).

Furthermore, the computing device 144 of the information reference/control terminal 140a of the operation manager sends data to the disclaimer agreement unit 222 through the input unit 241 for the operation manager to judge whether or not the decline in quality is due to the disclaimer. request. The data for determining whether or not the deterioration in quality is due to the disclaimer is, for example, the operation log 2120, the quality calculation result 2130, and the failure log 2140. The disclaimer sequential agreement section 222 acquires the requested data from the database 210 and transmits it to the information reference/control terminal 140a of the operation manager. The computing device 144 of the information reference/control terminal 140a of the operation manager displays the received data on the display unit 242 as related information (step 904).

Furthermore, in order for the operation manager to determine whether or not the deterioration in quality is due to the disclaimer, the arithmetic unit 144 of the information reference/control terminal 140a inputs, through the input unit 241, whether or not additional investigation of the data is necessary. (Step 905).

At step 906, the information reference/control terminal 140a of the operation manager performs processing to confirm whether additional investigation is necessary. If it is input that additional investigation is not necessary (No), the process proceeds to step 910. If it is input that additional investigation is necessary, the process advances to step 907.

At step 907, the computing device 144 of the information reference/control terminal 140a of the operation manager transmits an additional investigation request to the disclaimer sequential agreement section 222. The disclaimer sequential agreement unit 222 stores the additional investigation request as an investigation log in the failure log database 214, and transmits the additional investigation request regarding quality deterioration to the information reference/control terminal 140b of the site worker.

The computing device 144 of the information reference/control terminal 140b of the site worker displays the received additional investigation instruction on the display unit 242 (step 908). The arithmetic device 144 of the information reference/control terminal 140b of the site worker receives input of the investigation log regarding the additional investigation through the input section 241, and transmits the input investigation log to the disclaimer sequential agreement section 222 (step 909). . The disclaimer sequential agreement unit 222 stores the received investigation log in the failure log database 214. Then, the disclaimer sequential agreement unit 222 repeats the processing from step 904 to step 909 until it is input that additional investigation is unnecessary to determine whether or not the decline in quality is due to the disclaimer.

In step 910, the computing device 144 of the information reference/control terminal 140a of the operation manager receives, through the input unit 241, the input of the judgment result as to whether or not the quality deterioration is due to the disclaimer, and sends the input judgment result. The disclaimer is sequentially transmitted to the agreement section 222. The disclaimer sequential agreement unit 222 stores the determination result in the failure log database 214 as an investigation log.

The arithmetic device 144 of the information reference/control terminal 140c in charge of the customer side receives from the disclaimer sequential agreement section 222 the result that the quality deterioration is determined to be due to the disclaimer or by the operation manager, and the processing unit 144 of the information reference/control terminal 140c in charge of the customer side receives from the disclaimer sequential agreement unit 222 the result that the quality deterioration is determined to be due to the disclaimer or the operation manager, and displays information regarding the received disclaimer. The determination result is displayed on the display unit 242 (step 911). The arithmetic unit 144 of the information reference/control terminal 140c of the person in charge on the customer side inputs data (for example, operation logs, quality calculation results, failure logs) for determining whether or not the decline in quality is due to the disclaimer through the input unit 241. The input of the reference request is accepted, and the requested data is displayed on the display unit 242 (step 912).

In step S913, the arithmetic unit 144 of the information reference/control terminal 140c of the person in charge on the customer side receives, through the input unit 241, an input as to whether or not to approve the determination result as to whether or not the quality reduction is due to the disclaimer; The input approval result is transmitted to the disclaimer sequential agreement section 222. The disclaimer sequential agreement unit 222 stores the approval result in the failure log database 214 as an investigation log. Then, the arithmetic unit 144 of the information reference/control terminal 140c in charge of the customer side determines whether or not to approve the determination result as to whether or not the quality reduction is due to the disclaimer (step 913). If "remand" is input (No), the process proceeds to step 914, and if "approve" is input (Yes), the process proceeds to step 915.
Specifically, when "remand" is input, the disclaimer sequential agreement unit 222 informs the customer that the judgment result has been returned and requests re-judgment from the information reference/control terminal 140c of the person in charge on the customer side. receive.

In step 914, the computing device 144 of the information reference/control terminal 140a of the operation manager displays on the display unit 242 that the judgment result has been returned and a request for re-judgment, and the process returns to step 910. At this time, the disclaimer sequential agreement unit 222 transmits to the information reference/control terminal 140a of the operation manager that the judgment result has been returned and a request for re-judgment.
The processing from step 910 to step 914 is repeated until approval of the judgment result is input into the information reference/control terminal 140c of the person in charge on the customer side.

At step 915, the arithmetic unit 144 of the information reference/control terminal 140a of the operation manager receives, through the input unit 241, the input of the final agreement result as to whether or not it is based on the disclaimer. Then, the disclaimer sequential agreement unit 222 stores the final agreement result regarding whether or not the quality reduction is due to the disclaimer in the failure information (step 916), and the process of FIG. 9 ends.
