[0009] The following describes equipment maintenance systems, equipment maintenance methods, and programs to which the present invention is applied, with reference to the drawings.

[0010] (First Embodiment) Figure 1 is a block diagram showing an example of the equipment maintenance system 1 in the first embodiment. The machine maintenance system 1 includes, for example, a user terminal device 100, a monitoring device 200, a number of target devices 300, a maintenance support system 400, and a manufacturing plant device 500. The user terminal device 100, the monitoring device 200, the number of target devices 300, the maintenance support system 400, and the manufacturing plant device 500 have a communication interface (not shown) such as a NIC (Network Interface Card) or a wireless communication module for connecting to a communication network NW such as the Internet. The communication network NW may include, for example, a general-purpose network such as the Internet and a private network such as local 5G or WiFi (registered trademark).

[0011] The user terminal device 100 is an information processing device such as a personal computer or a smartphone operated by a user. The user in the embodiment is, for example, a person who owns the monitoring device 200 and the target device 300. The user terminal device 100 includes, for example, a display unit 102, an operation unit 104, a control unit 106, and a storage unit 108. The user terminal device 100 implements, for example, application software for receiving a service for managing the target device 300 by the maintenance support system 400.

[0012] The monitoring device 200 is an information processing device that acquires various information via the communication network NW and performs various processes. The monitoring device 200 includes, for example, a sensing unit 202, a component estimation unit 204, a model storage unit 20⑥, and a notification unit 208. The sensing unit 202, the component estimation unit 204, and the notification unit 208 are functional units realized by, for example, a processor such as a CPU (Central Processing Unit) executing a program stored in a program memory. The model storage unit 206 is a storage device such as a memory. Note that the monitoring device 200 may be directly connected to the target device 300 by means such as a coaxial cable.

[0013] The sensing unit 202 acquires sensing information from the target device 300. The sensing information is information indicating a sensor signal or an operating state related to an abnormality or a failure of the target device 300 or the target component 310. The target device 300 is a device to be monitored by the monitoring device 200. The target device 300 is, for example, equipment, devices, etc. included in a facility operated by a user. The facility operated by the user is, for example, a power system. The target device 300 includes the target component 310. The target component is a component to be subject to maintenance such as inspection, replacement, or repair by the user. The sensing unit 202 acquires, as sensing information, a sensor signal from the target device 300 by a sensor and operation information indicating the operating state of the target device 300.

[0014] The component estimation unit 204 inputs the sensing information of the target device 300 into a component estimation model and outputs the target component information and the disassembly range component information output from the component estimation model. The component identification information is information such as an ID number that uniquely identifies the target component 310. The disassembly range component information is information indicating components other than the target component 310 included in the range that needs to be disassembled for replacing or maintaining the target component 310. Also, the disassembly range component information may be information indicating maintenance work such as inspection that can be performed simultaneously with the target component 310 for each target component 310. The component identification information may be associated with the personnel information of the personnel who have worked on the target component 310 of the component identification information.

[0015] For example, if a device consists of parts a, b, c, d, and e, and parts a and b need to be disassembled in order to replace or repair part c, then parts a and b are considered parts within the scope of disassembly. Also, if a device consists of parts a, b, c, d, and e, and parts a and b are disassembled in order to replace or repair part c, and part d becomes replaceable or repairable, then parts a, b, and d may be considered parts within the scope of disassembly. Furthermore, if a device consists of parts a, b, c, d, and e, and parts a and b are disassembled in order to replace or repair part c, and part d becomes replaceable or repairable, and part e can be replaced or repaired depending on the skills of the personnel, then parts a, b, d, and e may be considered parts within the scope of disassembly.

[0016] The model storage unit 206 stores a component estimation model that associates sensing information of the target device 300 with target component information and disassembly range component information. The target component information is information indicating the target component 310 that needs to be replaced or maintained in the target device 300. The component estimation model is a machine learning model that, when sensing information of the target device 300 is input, outputs component identification information indicating the target component 310 that needs to be replaced or maintained in the target device 300, and disassembly range component information.

[0017] The notification unit 208 notifies the user of browsing information. The browsing information includes the target device 300, the estimated target part 310, and the disassembly range part information. The user terminal device 100 receives the browsing information. As a result, the user terminal device 100 can display the target device 300, the part identification information indicating the target part 310, and the part indicated by the disassembly range part information using the display unit 102.

[0018] The maintenance support system 400 is an information processing system that acquires various information via a communication network NW and performs various processing. The maintenance support system 400 includes, for example, an authentication unit 402, a proposal unit 404, an output control unit 406, an order unit 408, and a storage unit 410. The authentication unit 402, the proposal unit 404, the output control unit 406, and the order unit 408 are functional units that are realized, for example, by a processor such as a CPU executing a program stored in program memory. The storage unit 410 is a storage device such as memory.

[0019] The authentication unit 402 authenticates the user based on the user identification information. The authentication unit 402 may, for example, determine that authentication is successful when the user identification information obtained when the user terminal device 100 accesses the maintenance support system 400 matches the user identification information stored in the storage unit 410.

[0020] The proposal unit 404 creates proposal information. The proposal information is created by selecting parts that are included in the disassembly range required to disassemble the target equipment 300 when replacing or maintaining the target part 310 estimated by the part estimation unit 204, as recommended products that should be purchased at the same time as the target part 310. In other words, the proposal information is information that proposes replacing or maintaining the target part 310 and the recommended products.

[0021] The output control unit 406 outputs an order screen to the user for ordering the target part 310 estimated by the part estimation unit 204 and recommended products. The order screen is created based on the part browsing information. The order screen includes the target part 310 estimated by the part estimation unit 204, recommended products, and a work plan.

[0022] When the ordering unit 408 receives order information from a user indicating the target part 310 or recommended product estimated by the part estimation unit 204, it processes an order for the target part 310 or recommended product estimated by the part estimation unit 204 based on the order information. When the ordering unit 408 receives order information from a user indicating the target part 310 and recommended product estimated by the user, it processes an order for the target part 310 and recommended product based on the order information. The ordering unit 408 transmits the order information to the manufacturing equipment 500. For example, the ordering unit 408 requests the manufacturing equipment 500 to deliver the target part 310 and recommended product.

[0023] The factory equipment 500 is an information processing device managed by the factory. The factory equipment 500 includes, for example, a reception unit 502 and a manufacturing management unit 504. The reception unit 502 receives order information from the maintenance support system 400. The manufacturing management unit 504 manages the manufacturing schedule, inventory, etc., of equipment and parts. The factory equipment 500 also manages personnel who perform maintenance work on target parts 310 and recommended products. The factory equipment 500 manages personnel schedules and assigns personnel to work plans based on the schedule. Note that the factory equipment 500 is not limited to being managed by the factory; the same functions as the factory equipment 500 may be realized by a cloud server managed by an entity other than the factory.

[0024] Furthermore, the components of the monitoring device 200 and the maintenance support system 400 may be integrated into a single device, or they may be distributed across multiple devices in a configuration different from that of this embodiment. In addition, the manufacturing plant equipment 500 may be distributed across different devices, with the functions for managing the manufacturing of the target equipment 300 and target parts 310 being separated from the functions for managing personnel for maintenance work.

[0025] Figure 2 shows an example of a configuration for constructing a parts estimation model in the embodiment. The equipment maintenance system 1 may include a learning device 600 and a personnel terminal device 700. The learning device 600 is, for example, an information processing device that can communicate with the monitoring device 200 and the personnel terminal device 700 via a communication network NW. The personnel terminal device 700 is a smartphone or tablet terminal carried by personnel performing maintenance work on equipment and parts.

[0026] The learning device 600 includes, for example, an acquisition unit 602 and a learning unit 604. The acquisition unit 602 acquires feedback information (FB information) from the personnel terminal device 700. The feedback information indicates whether or not it was necessary to replace or maintain parts included in the disassembly range when the target equipment 300 and target parts 310 are replaced or maintained. The acquisition unit 602 may also acquire feedback information entered by technicians such as maintenance service technicians and designers who have reviewed work completion reports, etc.

[0027] The learning unit 604 trains the component estimation model to output target component information and decomposition range component information based on information indicating components included in feedback information when sensing information of the target device 300 is input to the component estimation model. The decomposition range component information as training data is information indicating components included in feedback information. The learning unit 604 updates the component estimation model by outputting information for updating the component estimation model's parameters to the model storage unit 206. The parameters of the component estimation model represent values ​​or weights that determine how to convert sensing information as input data to target component information and decomposition range component information as output data during inference.

[0028] In addition to suggesting orders for the target parts 310 and recommended products, the aforementioned maintenance support system 400 may also suggest a work plan. The storage unit 410 may store parts ordered according to the order information and work plans for maintenance or replacement that the user has referenced or purchased. The suggestion unit 404 then selects a work plan as a recommended product based on the target part information and disassembly scope part information output from the part estimation unit 204. The work plan is information including the work schedule and labor costs for the target equipment 300, target parts 310, or recommended product.

[0029] The proposal unit 404 calculates the work schedule based on the procurement period of the target part 310, the procurement period of the recommended product, and the availability of personnel to perform maintenance work on the target part 310 and the recommended product. The procurement period of the target part 310 and the recommended product is, for example, the manufacturing period of the target part 310 and the recommended product plus the period necessary to start maintenance work on the target part 310 and the recommended product, such as the transportation period for the target part 310 and the recommended product. The manufacturing period of the target part 310 and the recommended product is the period necessary to manufacture the target part 310 and the recommended product using the factory equipment 500. The manufacturing period of the target part 310 and the recommended product may be obtained, for example, by querying the factory equipment 500 for the manufacturing period of the target part 310 and the recommended product and based on the response from the factory equipment 500.

[0030] Furthermore, the manufacturing period for the target part 310 and the recommended product may be obtained based on inventory information indicating whether or not the manufacturing plant equipment 500 has stock of the target part 310. If the suggestion unit 404 determines that the target part 310 and the recommended product are in stock based on the inventory information, it may set the manufacturing period for the target part 310 and the recommended product to zero. If the suggestion unit 404 determines that the target part 310 and the recommended product are not in stock based on the inventory information, it may query the manufacturing plant equipment 500 for the manufacturing period for the target part 310 and the recommended product and obtain the manufacturing period based on the response to the query.

[0031] Whether or not inventory is available may be determined based on whether or not the user is a subscription member. A subscription member is a member who has entered into a contract to continuously pay a fee for having inventory of the target part 310 and recommended products. The proposal unit 404 determines that there is inventory of the target part 310 if the user information of the user being a subscription member is stored in the storage unit 414, and determines that there is no inventory of the target part 310 and recommended products if the user information of the user being a subscription member is not stored in the storage unit 410. In other words, if the user is a subscription member for the target part 310 and recommended products, the manufacturing period is set to zero because there is inventory of the target part 310 and recommended products. Furthermore, the proposal unit 404 calculates the labor cost based on the sales price of the target part 310, the sales price of the recommended product, and the work schedule and fees of the personnel. The personnel fee is, for example, the daily labor cost.

[0032] The proposal unit 404 may, for example, create a work plan that includes the work schedule and labor costs for replacing the target part 310, and a work plan that includes the work schedule and labor costs for replacing both the target part 310 and the recommended product. The work schedule for replacing both the target part 310 and the recommended product is set to be shorter than the total number of days for replacing the target part 310 alone and for replacing the recommended product alone.

[0033] If there is overlapping work in the work schedule for replacing the target part 310 individually and the work schedule for replacing the recommended product individually, the overlapping work can be omitted. In this case, the proposal unit 404 can subtract the work schedule for the omitted work from the combined schedule for replacing the target part 310 individually and the work schedule for replacing the recommended product individually to set a work schedule for replacing both the target part 310 and the recommended product. Overlapping work includes, for example, if the disassembly scope of the target equipment 300 overlaps between the target part 310 and the recommended product, the common work for the target equipment 300 and the operational test work for the target equipment 300.

[0034] The memory unit 410 may store disassembly items and restoration items for the parts included in the target device 300. Disassembly items indicate the work items to be taken apart for maintenance of the parts. Restoration items indicate the work items to be taken apart for restoration of the parts. The suggestion unit 404 refers to the information stored in the memory unit 410 and compares the disassembly items and restoration items of the target part 310 with the disassembly items and restoration items of the recommended part, and recognizes matching disassembly items and restoration items as tasks that can be omitted. The suggestion unit 404 then shortens the schedule for the tasks that can be omitted and creates a work schedule for replacing both the target part 310 and the recommended product.

[0035] The proposal unit 404 sets the labor cost for replacing both the target part 310 and the recommended product to be lower than the sum of the labor cost for replacing the target part 310 alone and the labor cost for replacing the recommended product alone.

[0036] The output control unit 406 outputs an order screen to the user for ordering the target parts 310 and recommended products estimated by the parts estimation unit 204, as well as a work plan.

[0037] Figure 3 is a sequence diagram showing an example of the processing procedure of the equipment maintenance system 1 in the embodiment. First, the monitoring device 200 collects sensing information from the target equipment 300 (step ST100), inputs the sensing information into a component estimation model, and estimates the target components 310 that need to be replaced, etc., and the components included in the disassembly range of the target equipment 300, based on the component identification information and disassembly range component information output from the component estimation model (step ST102).

[0038] Figure 4 shows an example of device sensor information in an embodiment. Device sensor information is an example of sensing information. Device sensor information is, for example, information that associates a user ID with a monitoring device, a sensor ID, and a model. The user ID is information that indicates the owner of the monitoring device 200 and the target device 300. The monitoring device is information that indicates the target device 300 or the target component 310. The model is information that indicates the signal format, processing, and output value of the sensor.

[0039] The monitoring device 200 transmits part viewing information S100 to the user terminal device 100, which includes part identification information of the estimated target part 310 and part identification information of the parts included in the disassembly range. The monitoring device 200 transmits part viewing information S100 based on pre-configured notification destination information.

[0040] Figure 5 shows an example of notification destination information in the embodiment. The notification destination information is, for example, information that associates a user ID, monitoring equipment information, part information, serial number information, and notification information. The monitoring device 200 compares the part identification information with the monitoring equipment information and part information included in the notification destination information, and if the part identification information matches the monitoring equipment information or part, it transmits part viewing information S100 to the user terminal device 100 of the notification destination information.

[0041] Upon receiving the parts viewing information S100, the user terminal device 100 transmits information (S102) indicating an authentication request to the maintenance support system 400. The maintenance support system 400 performs an authentication process based on the authentication request and transmits information (S102) indicating the authentication result to the user terminal device 100.

[0042] Figure 6 shows an example of user information in an embodiment. User information is, for example, information that associates a user ID, username, company name, membership type, and monitoring equipment information. Membership type information may, for example, indicate whether the user is a subscription member who continuously pays a fee to secure inventory of the target part 310. The user terminal device 100 includes the user ID in the authentication request, and the maintenance support system 400 performs authentication based on the user ID in the user information stored in the storage unit 410.

[0043] The user terminal device 100 transmits information (S104) indicating a viewing request that includes part identification information, and the maintenance support system 400 transmits information (S104) to the user terminal device 100 for viewing part viewing information based on the viewing request. This allows the user terminal device 100 to allow the user to recognize the target part 310 and the parts included in the disassembly range.

[0044] The maintenance support system 400 creates proposal information (step ST104). The maintenance support system 400 selects parts included in the disassembly scope when replacing or maintaining the target part 310 as recommended products to be purchased at the same time as the target part 310. The maintenance support system 400 also selects personnel based on the item work information and creates a work schedule from the availability information of the selected personnel. The maintenance support system 400 creates a work fee based on the selected personnel, the number of personnel, and the work schedule.

[0045] Figure 7 shows an example of item handling information in the embodiment. The item work information is information that associates equipment information, part identification information, work information, process information, and essential skills information. Work information is, for example, information that indicates the work required to perform maintenance such as replacement or repair of the target equipment 300, target part 310, and recommended products. Process information is information that indicates the maintenance process or number of days. Essential skills information is information that indicates the skills of the factors required for maintenance. It is desirable for the proposal unit 404 to select personnel who meet the requirements of the target part 310 indicated by the part identification information, the work indicated by the work information, the process or number of days indicated by the process information, and the skills indicated by the essential skills information.

[0046] Figure 8 shows an example of personnel information for the embodiment. The proposal unit 404 may create proposal information using the personnel information stored in the storage unit 410. Personnel information includes, for example, personnel identification information (personnel ID), job type information, job function information, rank, location information, equipment and parts information, work information, skill information, and personnel schedule information (schedule information). Personnel identification information is information that identifies a personnel. Job type information is information that indicates the job type of the personnel. Job type information is, for example, information that indicates the role at the maintenance site, such as worker or instructor. Job function information is information that indicates the job function of the personnel. Job function information is, for example, information that indicates the specific abilities of the personnel. The proposal unit 404 selects personnel with job type and job function that match the maintenance content of the target part 310. Rank information indicates a rank calculated based on the personnel's experience, such as the number of times they have performed a task. Location information indicates the location of the personnel. Equipment identification information and component identification information indicate the equipment and components that the personnel can handle. Task information indicates the tasks that the personnel can handle. Skill information indicates the skills possessed by the personnel. Personnel scheduling information indicates the dates and locations on which personnel can be dispatched, such as the date and time of work and the work location. By referring to the personnel information, the maintenance support system 400 can select personnel who can handle the target part 310 in the part identification information and select personnel whose schedules are free after the procurement period.

[0047] Figure 9 shows an example of proposed information in an embodiment. The proposed information includes, for example, parts information, plan candidate information, simultaneous replacement / maintenance information, alternative parts information, and simultaneous purchase information. Plan candidate information includes multiple work plan candidates with different work schedules and service fees. Simultaneous replacement / maintenance information indicates recommended products to be replaced at the same time as the target part 310, or work to be performed at the same time. Alternative parts information indicates parts that can be substituted for the target part 310. Alternative parts information is proposed when the target part 310 is unavailable or out of stock. Simultaneous purchase information is information that suggests purchasing parts necessary for the maintenance of the target part 310 and recommended products at the same time as the target part 310.

[0048] The maintenance support system 400 sends information S106 to the user terminal device 100 that displays an order screen based on the created proposal information, and the user terminal device 100 displays an order screen including a work plan (step ST106). The user terminal device 100 accepts an operation to order the target part 310, recommended products, and work plan. The user terminal device 100 sends order information S108 to the maintenance support system 400 based on the accepted operation.

[0049] Figure 10 shows an example of order information in an embodiment. Order information includes, for example, order ID, order date, user ID, target equipment information, target part information, work plan information, option information, address information, and contact person information. Work plan information may vary depending on whether the customer is a subscription member or a regular member who pays the fee at the time the maintenance work is determined. Option information includes, for example, recommended parts to be replaced simultaneously with the target part 310, maintenance work to be performed simultaneously, and parts that can be substituted for the target part 310.

[0050] The maintenance support system 400 receives order information, processes the order for the target parts 310 and the selected work plan based on the order information (step ST108), and transmits the order information S110 to the factory equipment 500.

[0051] Figure 11 shows an example of part browsing information S100 in an embodiment. In the sequence described above, the notification unit 208 may send an email to the user terminal device 100 containing URL information (link) of sensing information (sensor analysis value), URL information of part A as the target part 310, and URL information of part B as a recommended product. The email may also include a message prompting the replacement of part A and a message prompting the simultaneous replacement of part B. The user terminal device 100 displays the links contained in the received email on the display unit 102 using its email software. If a link is selected based on the user's operation, the user terminal device 100 accesses the external site and sends a viewing request to the maintenance support system 400.

[0052] Figure 12 shows an example of an order screen in the embodiment. The order screen includes, for example, equipment information for part A as the target part 310 and equipment information for part B as a recommended product, maintenance information for part A and maintenance information for part B, an order request button, and a quote request button. The equipment information includes, for example, a message indicating that part A as the target part 310 and part B as a recommended product have been estimated, image information for part A and part B respectively, and price information for part A and part B respectively.

[0053] The maintenance information includes a message for selecting either maintenance plan A, which replaces or maintains both parts A and B, or maintenance plan B, which replaces or maintains only part A; the schedule and fees for each maintenance plan; and multiple buttons corresponding to each maintenance plan. When one or both of the multiple buttons corresponding to each maintenance plan are selected, the user terminal device 100 outputs the order information for the selected maintenance plan.

[0054] Figure 13 shows another example of the order screen in the embodiment. The order screen may include maintenance plan A for parts A and B, and maintenance plan B for part A, and may include detailed information for each maintenance plan, an order request button and a quote request button for each maintenance plan. The detailed information may include, for example, the work name, the delivery destination and work location for the target part 310, the work schedule, the number of workers, and the equipment.

[0055] As described above, the equipment maintenance system 1 of this embodiment notifies the user of the target parts 310 and recommended products estimated based on sensing information of the target equipment 300, and allows the user to view an order screen. Furthermore, the equipment maintenance system 1 allows the user to view proposed information including a work plan for maintaining the target equipment 300, target parts 310, and recommended products. Thus, the equipment maintenance system 1 can provide an environment for ordering parts in order to efficiently perform equipment maintenance.

[0056] (Second Embodiment) In the second embodiment, the learning unit 604 is trained to output target part information, disassembly range part information, importance information, and urgency information when sensing information is input to the part estimation model. The part estimation unit 204 inputs sensing information of the target device 300 to the part estimation model and acquires the target part information, disassembly range part information, importance information, and urgency information output from the part estimation model.

[0057] The notification unit 208 notifies the user terminal device 100 of the target part information, disassembly range part information, importance information, and urgency information estimated by the part estimation unit 204. As a result, the user terminal device 100 displays the target part 310, recommended part, importance, and urgency.

[0058] When the suggestion unit 404 receives priority information from the user terminal device 100, it selects recommended products based on the priority information. The priority information is information indicating how much priority should be given to maintenance work, such as the level of importance, the level of urgency, and the deadline for maintenance work. The higher the importance, the higher the priority, and the higher the urgency, the higher the priority. In addition, the component identification information may have a priority set for each component by configuration information. The configuration information may be, for example, equipment or components owned by the user, with priority set based on the user's request.

[0059] The proposal unit 404 calculates the work schedule based on priority, the procurement period of the target part 310, the procurement period of the recommended part, and the availability of personnel to perform maintenance work on the target part 310 and the recommended product. The proposal unit 404 calculates the work schedule in a way that shortens the time from order to completion of maintenance work for higher priority items. The proposal unit 404 also calculates the work fee based on the sales price of the target part 310, the sales price of the recommended part, and the work schedule and fees of the personnel. The proposal unit 404 may add a surcharge to the work fee for work schedules calculated taking into account high priority.

[0060] The proposal unit 404 may, for example, create a work plan that includes a work schedule and labor costs for urgently replacing the target part 310 due to its high priority, and a work plan that includes a work schedule and labor costs for replacing the target part 310 with sufficient time to spare, as it is not urgent.

[0061] Importance information indicates the importance of the target component 310. While the importance information represents the importance of the target component 310, it is not limited to this; the importance may include the importance of both the target component 310 and the recommended product. The urgency information indicates the urgency of the target part 310 or the recommended part. The urgency information is the urgency of the target part 310, but is not limited to that; the urgency may include the urgency of both the target part 310 and the recommended product. Priority information is the priority of the target part 310, but is not limited to this; urgency may include a priority that encompasses both the target part 310 and the recommended product.

[0062] The importance of a component 310 is an indicator of whether it affects the overall function or stability of the system in which the component 300 is included. For example, components that play a core and primary role in a power system, such as generators, transformers, and major transmission lines, have a higher importance. Furthermore, the greater the contribution of the component 310 or recommended component to the reliability or safety of the system, the higher its importance. Also, the wider the area of ​​the system affected by the failure of the component 310 or recommended component, the higher its importance. In addition, if there is no alternative for the component 310 or recommended component, its importance is high, and if there is an alternative, its importance is low.

[0063] The importance of the target component 310 or recommended component may fluctuate based on sensing information from the target device 300. When the values ​​detected by the sensors of the target device 300 become abnormal, the impact of the target device 300 on the entire system increases, and the importance of the target component 310 or recommended component increases. Also, during times or seasons when the load on the target device 300 is high, the importance of the target component 310 or recommended component increases, and during times or seasons when the load on the target device 300 is low, the importance of the target component 310 or recommended component decreases. Furthermore, when the backup system of the target device 300 is operating, the importance of the target component 310 or recommended component decreases, and when the backup system of the target device 300 fails, the importance of the target component 310 or recommended component increases.

[0064] The urgency of a target component 310 or recommended component is an indicator of how quickly a response is needed if the target component 310 or recommended component fails or malfunctions. For example, components that require immediate attention, such as power transmission lines in a power system that lose function if disconnected, or components that pose a fire hazard, have a higher urgency. Components that cause rapid spread of impact when they fail or malfunction also have a higher urgency. Components that require a high amount of time or cost to restore also have a higher urgency. Furthermore, if there is no alternative for a target component 310 or recommended component, the urgency of that component 310 or recommended component increases. Additionally, the greater the contribution of a target component 310 or recommended component to the reliability or safety of the system, the higher the urgency. If there is an alternative for a target component 310 or recommended component, the urgency of that component decreases. Finally, auxiliary components in the target equipment 300 or recommended component have a lower urgency.

[0065] The urgency information for the target component 310 or recommended component may fluctuate based on the sensing information of the target device 300. The urgency of the target component 310 or recommended component increases when the value detected by the sensor of the target device 300 becomes abnormal, as this increases the likelihood of immediate action. Furthermore, the urgency of the target component 310 or recommended component increases during times or seasons when the load on the target device 300 is high, and decreases during times or seasons when the load on the target device 300 is low. In addition, the urgency of the target component 310 or recommended component decreases when the backup system of the target device 300 is operating, and increases when the backup system of the target device 300 is malfunctioning. Moreover, the urgency of the target component 310 or recommended component increases if a fire or other trouble occurs in equipment or components around the target device 300. The urgency of the target component 310 or recommended component increases based on reports from the administrator (control center or inspector) of the target equipment 300, which are used as sensing information for the target equipment 300.

[0066] Figure 14 is a sequence diagram showing an example of the processing procedure of the equipment maintenance system 1 in the second embodiment. First, the monitoring device 200 collects sensing information from the target equipment 300 (step ST100), inputs the sensing information into a component estimation model, and outputs component identification information, disassembly range component information, importance information, and urgency information from the component estimation model (step ST102A). Based on this, the monitoring device 200 estimates the target component 310 and recommended components.

[0067] The monitoring device 200 transmits part viewing information S100A to the user terminal device 100, which includes part identification information, disassembly scope information, importance information, and urgency information for the estimated target part 310. The monitoring device 200 transmits part viewing information S100A based on pre-configured notification destination information. The disassembly scope information corresponds to the part identification information of the recommended part.

[0068] Upon receiving the parts viewing information S100A, the user terminal device 100 transmits information (S102) indicating an authentication request to the maintenance support system 400. The maintenance support system 400 performs an authentication process based on the authentication request and transmits information (S102) indicating the authentication result to the user terminal device 100.

[0069] The user terminal device 100 transmits information (S104) indicating a viewing request that includes part identification information, and the maintenance support system 400 transmits information (S104) to the user terminal device 100 for viewing part viewing information based on the viewing request. This allows the user terminal device 100 to recognize the target part 310, recommended parts, importance information, and urgency information. Based on the estimated target part 310, recommended parts, importance information, and urgency information, the user terminal device 100 transmits priority information S106 to the maintenance support system 400. Priority is an indicator that shows whether to prioritize maintenance work on the target part 310, taking into account importance, urgency, and the deadline specified by the user.

[0070] The maintenance support system 400 creates proposal information based on priority information S106 (step ST104). Based on the priority, the maintenance support system 400 selects personnel based on item work information and creates a work schedule from the availability information of the selected personnel. The maintenance support system 400 creates a work fee based on the selected personnel, the number of personnel, and the work schedule. If the priority is high, the maintenance support system 400 selects personnel and creates a work schedule to complete the maintenance work in a short period of time. For example, if the priority is expressed in 1 to 3 stages in descending order of priority, and the baseline priority is set to 2, the maintenance support system 400 determines that the priority is high when the priority is 1.

[0071] Figure 15 shows an example of maintenance work history information in the embodiment. If there are multiple target parts 310 and recommended parts for the target equipment 300, the proposal unit 404 determines the priority of each target part 310 and recommended part based on urgency (warning level) and importance, and sets the desired deadline for maintenance work so that maintenance work on the target parts 310 and recommended parts with higher priority is completed first.

[0072] The maintenance support system 400 sends information S106 to the user terminal device 100 that displays an order screen based on the created proposal information, and the user terminal device 100 displays an order screen including a work plan (step ST106). The user terminal device 100 accepts an operation to order the target part 310, recommended parts, and work plan. The user terminal device 100 sends order information S108 to the maintenance support system 400 based on the accepted operation.

[0073] The maintenance support system 400 receives order information, processes orders for the target parts 310, recommended parts, and selected work plans based on the order information (step ST108), and transmits the order information S110 to the factory equipment 500.

[0074] As described above, the equipment maintenance system 1 of the second embodiment also provides an environment for ordering parts in order to efficiently perform maintenance on the target part 310. Furthermore, according to the equipment maintenance system 1 of this embodiment, when sensing information is input to the component estimation model, it is trained to output target component information, disassembly range component information, importance information, and urgency information. By inputting sensing information from the target equipment 300 to the component estimation model, target component information, disassembly range component information, importance information, and urgency information can be obtained and notified. Thus, according to the equipment maintenance system 1, the accuracy of the disassembly range component information, importance information, and urgency information notified can be improved by continuously training the component estimation model.
