The equipment configuration information includes, for example, customer ID, equipment ID, unit configuration information, and parts configuration information.

[0029] <Work Instruction Creation Process> Figure 14 is a flowchart showing the procedure for creating work instructions performed by the integrated maintenance information management system 3.

[0030] (Step S101) The maintenance information integrated management system 3 determines whether or not a request for the creation of a work order has been made, that is, whether or not a request for the creation of a work order has been made by an operator via the operator terminal 5. If a request for the creation of a work order has been made (step S101: YES), the maintenance information integrated management system 3 proceeds to step S102. If there is no request for the creation of a work order (step S101: NO), the maintenance information integrated management system 3 continues to perform the determination in step S101.

[0031] (Step S102) The maintenance information integrated management system 3 creates a work order based on information entered by the worker, referencing at least multiple databases, including the equipment configuration information DB 313. Subsequently, the maintenance information integrated management system 3 proceeds to step S103.

[0032] (Step S103) The maintenance information integrated management system 3 sends the created work order to the worker terminal 5. The worker terminal 5 displays the received work order on its screen in a predetermined manner. After that, the maintenance information integrated management system 3 returns to step S101.

[0033] <Report Information Creation Process> Figure 15 is a flowchart showing the procedure for creating report information performed by the integrated maintenance information management system 3.

[0034] (Step S201) The maintenance information integrated management system 3 determines whether or not a request for input of a work completion report has been made, that is, whether or not a request for input of a work completion report has been made by the worker who has completed the maintenance work through the worker terminal 5. If a request for input of a work completion report has been made (step S201: YES), the maintenance information integrated management system 3 proceeds to step S202. If there is no request for input of a work completion report (step S201: NO), the maintenance information integrated management system 3 continues to make the determination in step S201.

[0035] (Step S202) The maintenance information integrated management system 3 presents a report input screen to the worker terminal 5, which is a screen for receiving work completion reports from the worker. Subsequently, the maintenance information integrated management system 3 proceeds to step S203.

[0036] (Step S203) The maintenance information integrated management system 3 determines whether the worker has completed entering the work completion report via the report input screen. If the worker has completed the input (step S203; YES), the maintenance information integrated management system 3 proceeds to step S204. If the worker has not completed the input (step S203; NO), the maintenance information integrated management system 3 continues to perform the determination in step S203.

[0037] (Step S204) The maintenance information integrated management system 3 creates report information based on the information entered by the worker and information obtained by referring to at least the equipment configuration information DB313 based on that information. Subsequently, the processing of the maintenance information integrated management system 3 proceeds to step S205.

[0038] (Step S205) The maintenance information integrated management system 3 saves the created report information to the report information DB 310. After that, the maintenance information integrated management system 3 returns to step S201.

[0039] <Device Configuration Information Database Update Process> Figure 16 is a flowchart showing the procedure for updating the equipment configuration information database, which is performed by the integrated maintenance information management system 3. The integrated maintenance information management system 3 periodically performs the equipment configuration information database update process.

[0040] (Step S301) The maintenance information integrated management system 3 refers to the report information DB 310 to determine whether there is any undetected report information indicating unit and / or part replacement. If there is any undetected report information indicating unit and / or part replacement (step S301; YES), the maintenance information integrated management system 3 proceeds to step S302. If there is no undetected report information indicating unit and / or part replacement (step S301; NO), the maintenance information integrated management system 3 terminates the equipment configuration information DB update process for this cycle.

[0041] (Step S302) The integrated maintenance information management system 3 updates the unit replacement history DB311 and the parts replacement history DB312 based on the report information. Subsequently, the integrated maintenance information management system 3 proceeds to step S303.

[0042] (Step S303) The maintenance information integrated management system 3 updates the equipment configuration information DB 313 based on the updated information in the unit replacement history DB 311 and the parts replacement history DB 312, respectively. After that, the maintenance information integrated management system 3 terminates the equipment configuration information DB update process for this cycle.

[0043] As described above, according to the maintenance system 1 of this embodiment, the maintenance information integrated management system 3 includes an equipment information DB 301 that stores information about the equipment at the time of sale, and an equipment configuration information DB 313 that stores equipment configuration information regarding the latest configuration of equipment in which units and / or parts have been replaced due to maintenance work. This makes it possible to accurately manage information about the equipment configuration even after the sale.

[0044] Furthermore, by creating work instructions for maintenance workers by referring to at least the equipment configuration information DB313 and presenting them to the workers, accurate maintenance information can be provided to the workers. This enables efficient maintenance response, and as a result, it becomes possible to provide optimal services to customers at a low cost.

[0045] (Variation 1) The maintenance information integrated management system 3 may be configured to monitor each database to be monitored based on an alert generation condition table as shown in Figure 17. The alert generation condition table is a data table in which alert generation conditions are registered and is stored in the auxiliary storage device provided by the maintenance information integrated management system 3 as described above. In this configuration, the maintenance information integrated management system 3 includes an alert monitoring unit (not shown). The alert monitoring unit is an example of the alert monitoring means related to this disclosure. The alert monitoring unit monitors each database provided by the maintenance information integrated management system 3 based on the alert generation conditions registered in the alert generation condition table.

[0046] When the alert monitoring unit detects a database that matches the alert conditions, it generates alert information that includes the alert ID for the alert conditions, the ID of the database, the equipment ID, the reason for the alert, etc., and assigns an alert history ID to it. The generated alert information is then saved to the alert history database (not shown). The alert history database is a database where alert information is stored and is stored in the auxiliary storage device mentioned above. For example, if the alert conditions table is as shown in Figure 17, and today is August 30, 2024, then the database labeled "A001" (e.g., parts replacement history database 312) shown in Figure 18 is detected as the corresponding database. In this case, the alert monitoring unit generates alert information based on the record with parts replacement history ID "1000001" in the database shown in Figure 18 and saves it to the alert history database.

[0047] This makes it easier to detect equipment whose legal inspection deadline is approaching, or equipment containing parts nearing the end of their lifespan. Furthermore, the work instruction creation unit 30 also refers to the alert history database when creating work instructions. This allows workers to perform inspections and maintenance simultaneously, for example, by replacing parts that need replacing due to end-of-life during legal inspections. As a result, the number of visits can be reduced, leading to cost savings.

[0048] (Modification 2) In the configuration of the maintenance information integrated management system 3 of Modification 1, the alert information stored in the alert history DB may be referenced by the maintenance reception system 2. In this case, the maintenance reception system 2 includes an alert information reference unit (not shown) that references the alert information stored in the alert history DB, and an alert issuance unit (not shown). The alert issuance unit issues an alert to the corresponding customer based on the alert information referenced by the alert information reference unit. The above-mentioned alert information reference unit and alert issuance unit are examples of the alert information reference means and alert issuance means related to this disclosure, respectively.

[0049] This makes it easy for the maintenance request system 2 to identify equipment whose legal inspection deadline is approaching, equipment containing parts nearing the end of their lifespan, etc., and to notify customers who own such equipment accordingly.

[0050] (Variation 3) The maintenance request system 2 may consist of multiple separate servers or other devices. Similarly, the maintenance information integrated management system 3 may consist of multiple separate servers or other devices.

[0051] (Modification 4) All or part of the functional components of the maintenance reception system 2 (see Figure 2) may be implemented using dedicated hardware. Similarly, all or part of the functional components of the maintenance information integrated management system 3 (see Figure 8) may be implemented using dedicated hardware. Dedicated hardware includes, for example, single circuits, complex circuits, programmed processors, ASICs (Application-Specific Integrated Circuits), FPGAs (Field-Programmable Gate Arrays), or combinations thereof.

[0052] The technical concepts related to each of the above-described modifications may be implemented individually or in combination as appropriate.

[0053] This disclosure allows for various embodiments and modifications without departing from its broad spirit and scope. Furthermore, the embodiments described above are for illustrative purposes only and do not limit the scope of this disclosure. In other words, the scope of this disclosure is defined by the claims, not by the embodiments. Various modifications made within the scope of the claims and the equivalent significance of the disclosure are considered to be within the scope of this disclosure. [Explanation of Symbols]
