[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 equipment 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, a factory device 500, and a maintenance contractor device 600. The user terminal device 100, the monitoring device 200, the number of target devices 300, the maintenance support system 400, the factory device 500, and the maintenance contractor device 600 have a communication interface (not shown), such as a NIC (Network Interface Card) or 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®.

[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 user may own a work support device 120. The work support device 120 is a device for supporting the maintenance work of the target device 300 or the facility owned by the user including the target device 300. The facility operated by the user is, for example, a power system. The work support device 120 is, for example, a device for supporting the maintenance work of personnel such as an inspection device for the target device 300, a device used by personnel in inspection work, a transport device for the target device 300, and a device used by personnel in the replacement or repair of the target device 300.

[0013] 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.

[0014] 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 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, from the target device 300, a sensor signal from a sensor and operating information indicating the operating state of the target device 300 as sensing information.

[0015] Based on the sensing information of the target device 300 and the component estimation model, the component estimation unit 204 estimates the target component 310 and outputs component identification information indicating the target component 310. The component identification information is information such as an ID number that uniquely identifies the target component 310. The component identification information may be associated with information indicating a person who has worked on the target component 310 of the component identification information.

[0016] The model storage unit 206 stores a component estimation model in which the sensing information of the target device 300 is associated with 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 learned to output component identification information indicating the target component 310 that needs to be replaced or maintained in the target device 300 when the sensing information of the target device 300 is input.

[0017] The notification unit 208 notifies the user of the target device 300 of component viewing information. The component viewing information is information indicating information for viewing the target component 310 estimated by the component estimation unit 204. The user terminal device 100 receives the component viewing information. Thereby, the user terminal device 100 can display the target component 310 estimated to need replacement or maintenance based on the component viewing information on the display unit 102.

[0018] The part estimation unit 204 may output a confidence score in addition to the part identification information. The confidence score is a value indicating the likelihood of the estimated part identification information. If the confidence score exceeds a set value, the part estimation unit 204 may have the notification unit 208 notify the user terminal device 100 of part viewing information including the part identification information. The maintenance support system 400 may also have the notification unit 208 notify the user terminal device 100 of the part viewing information and the confidence score.

[0019] The component estimation model is learned by the monitoring device 200, but is not limited to this; it may also be learned by an information processing device separate from the monitoring device 200. The monitoring device 200 acquires data as training data that combines sensing information and target part information indicating the target part 310 that needs to be replaced or maintained. The sensing information includes, for example, the target device 300 or target part 310 that is the source of the information output, the type of signal, and its value. The sensing information may also be information that was referenced to determine that the target part 310 needs to be replaced or maintained. The sensing information may also be data output from the faulty or abnormal target part 310, data detecting the operation of the faulty or abnormal target part 310, or data output from the target device 300 that contains the faulty or abnormal target part 310, or data detecting the operation of the target device 300 that contains the faulty or abnormal target part 310.

[0020] The monitoring device 200 learns a component estimation model based on acquired training data so that when sensing information of the target device 300 is input, it outputs target component information indicating the target component 310 that needs to be replaced or maintained in the target device 300. The learning unit 212 updates the component estimation model by outputting information for updating the parameters of the component estimation model 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 as output data during inference.

[0021] 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. 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.

[0022] The maintenance provider device 600 is an information processing device managed by a maintenance provider. The maintenance provider device 600 includes, for example, a personnel management unit 602 and a work support equipment management unit 604. The personnel management unit 602 manages the schedule information of personnel for maintenance work. The work support equipment management unit 604 manages the schedule information of work support equipment. The maintenance provider device 600 receives order information for maintenance work included in the maintenance plan from the maintenance support system 400. The maintenance provider device 600 assigns personnel and work support equipment to the accepted maintenance work. Note that the maintenance provider device 600 is not limited to being managed by a maintenance provider; the same functions as the maintenance provider device 600 may be realized by a cloud server managed by a party other than a maintenance provider.

[0023] The maintenance company possesses work support equipment 610. Work support equipment 610 is equipment for supporting maintenance work on the target equipment 300 or the system containing the target equipment 300. Work support equipment is equipment for supporting maintenance work by personnel, such as inspection equipment for the target equipment 300, equipment used by personnel in inspection work, transport equipment for the target equipment 300, and equipment used by personnel in the replacement or repair of the target equipment 300. In the following explanation, when referring to both work support equipment 120 and work support equipment 610 collectively, they may simply be referred to as "work support equipment."

[0024] 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 item management unit 402, an authentication unit 404, a proposal unit 406, an output control unit 408, an ordering unit 410, a storage unit 412, a work support equipment storage unit 414, and an acquisition unit 416. The item management unit 402, the authentication unit 404, the proposal unit 406, the output control unit 408, the ordering unit 410, and the acquisition unit 416 are functional units realized by, for example, a processor such as a CPU executing a program stored in program memory. The storage unit 412 and the work support equipment storage unit 414 are storage devices such as memory.

[0025] The inventory management unit 402 calculates the procurement period for the target part 310 based on the manufacturing period of the target part 310 indicated by the part identification information. The manufacturing period of the target part 310 is the period required to manufacture the target part 310 using the factory equipment 500. The manufacturing period of the target part 310 may be obtained, for example, by querying the factory equipment 500 for the manufacturing period of the target part 310 and based on the response from the factory equipment 500. Furthermore, the manufacturing period of the target part 310 may be obtained based on inventory information indicating whether or not the factory equipment 500 has stock of the target part 310. If the inventory management unit 402 determines that there is stock of the target part 310 based on the inventory information, it may set the manufacturing period of the target part 310 to zero. If the inventory management unit 402 determines that there is no stock of the target part 310 based on the inventory information, it may inquire with the factory equipment 500 about the manufacturing period of the target part 310 and obtain the manufacturing period based on the response to the inquiry. Whether or not an item is in stock may be determined by 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 the target part 310 in stock. The inventory management unit 402 determines that the target part 310 is in stock if the user information of the subscription member is stored in the storage unit 412, and determines that the target part 310 is not in stock if the user information of the subscription member is not stored in the storage unit 412. In other words, if the user is a subscription member for the target part 310, the manufacturing period is set to zero because the target part 310 is in stock. The procurement period for the target part 310 is, for example, the manufacturing period of the target part 310 plus the period necessary to start maintenance work on the target part 310, such as the transportation period for the target part 310.

[0026] The authentication unit 404 authenticates the user based on the user identification information. The authentication unit 404 may, for example, determine that authentication is successful when the user identification information obtained when the user terminal device 100 accessed the maintenance support system 400 matches the user identification information stored in the storage unit 412.

[0027] The proposal unit 406 creates proposal information and notifies the user of the created proposal information. The proposal information includes a work plan in which the work schedule and work charges for the target equipment 300 and target parts 310 are determined based on the procurement period calculated by the inventory management unit 402. The proposal information may include multiple work plans with different work schedules and work charges.

[0028] The proposal unit 406 obtains information from the monitoring device 200 indicating the target equipment 300 and the target parts 310. The proposal unit 406 calculates the work schedule based on the procurement period of the target parts 310 and the availability of personnel to perform maintenance work on the target parts 310. The proposal unit 406 also calculates the work fee based on the sales price of the target parts 310 and the work schedule and fees of the personnel.

[0029] The output control unit 408 causes the user terminal device 100 to output an order screen for ordering a work plan. The order screen is created based on the parts browsing information. The order screen includes the target parts 310 estimated by the parts estimation unit 204 and multiple work plans included in the suggested information.

[0030] When the ordering unit 410 receives order information indicating the target part 310 estimated by the part estimation unit 204 and the work plan selected by the user, it processes an order for the target part 310 and the selected work plan based on the order information. The ordering unit 410 transmits the order information for the target part 310 to the factory equipment 500. The ordering unit 410 transmits the order information, including the work schedule of the work plan, to the maintenance company equipment 600.

[0031] The work support equipment storage unit 414 stores the estimated target part 310, the work support equipment, and time calculation information for calculating the time required to perform work on the target part 310 using the work support equipment, in association with each other. The work support equipment storage unit 414 also stores schedule information including the availability date, location of use, and user of the work support equipment.

[0032] The time calculation information is information indicating the time difference between the time spent on maintenance work performed without using work support equipment and the time spent on maintenance work performed with work support equipment. The time calculation information may also be information that associates the type or identification information of the work support equipment with the capacity information of the work support equipment and the time that can be shortened. The work support equipment may include either or both of work support equipment 120 or work support equipment 610.

[0033] The proposal unit 406 determines, based on the information stored in the work support equipment storage unit 414, whether or not work support equipment can be used in the work schedule for the target equipment 300 and target parts 310. If work support equipment can be used, the proposal unit 406 proposes a work schedule and work fee that is shorter than the number of work days if work support equipment is not used.

[0034] Furthermore, the components of the monitoring device 200, the maintenance support system 400, the factory equipment 500, and the maintenance contractor equipment 600 may be integrated into a single device, or they may be distributed across multiple devices in a configuration different from that of this embodiment.

[0035] Figure 2 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 component 310 that needs to be replaced or otherwise determined based on the component identification information output from the component estimation model (step ST102).

[0036] Figure 3 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 with 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.

[0037] The monitoring device 200 transmits part viewing information S100 to the user terminal device 100 based on the estimated part identification information of the target part 310. The monitoring device 200 transmits part viewing information S100 based on pre-configured notification destination information.

[0038] Figure 4 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.

[0039] 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.

[0040] Figure 5 shows an example of user information in an embodiment. User information is, for example, information that associates user identification information (user ID), username, company name information, membership type information, 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 user identification information in the authentication request, and the maintenance support system 400 performs authentication based on the user identification information in the user information stored in the storage unit 412.

[0041] The user terminal device 100 transmits part identification information S104, and the maintenance support system 400 transmits part viewing information S106 to the user terminal device 100 for viewing the target part 310 based on the part identification information S104.

[0042] The maintenance support system 400 calculates the procurement period for the target part 310 (step ST104) and creates proposal information (step ST106). Based on the calculated procurement period and item work information, the maintenance support system 400 selects personnel and creates a work schedule from the schedule information of the selected personnel. Based on the selected personnel, the number of personnel, and the work schedule, the maintenance support system 400 creates a work fee.

[0043] Figure 6 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 or target part 310. Process information is information that indicates the maintenance process or number of days. Essential skills information is information that indicates the skills of factors necessary for maintenance. It is desirable for the proposal unit 406 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.

[0044] Figure 7 shows an example of work support equipment information in an embodiment. The work support equipment storage unit 414 stores information that associates the target part 310 with work support equipment information and shortened work period information for supporting maintenance work on the target part 310. The work support equipment information may also be information that associates the equipment information of the target equipment 300, part information, work information, process information, identification information of the work support equipment, and shortened work period information. The proposal unit 406 can shorten the work schedule created by selecting personnel by the amount of the shortened work period when work support equipment corresponding to the maintenance work and process of the target equipment 300 and the target part 310 is used.

[0045] Figure 8 shows an example of proposed information in an embodiment. The proposed information includes, for example, parts information, plan candidate information, simultaneous replacement / maintenance information, procurement period information, work support equipment information, work days information, and work fee information. Plan candidate information shows each of several work plan candidates with different work schedules and work fees. Simultaneous replacement / maintenance information shows parts to be replaced or maintenance work performed simultaneously with the target part 310. Procurement period information shows the procurement period for the target part 310. Work support equipment information, work days information, and work fee information show the work days and work fees corresponding to the work support equipment.

[0046] The maintenance support system 400 sends browsing information S106 to the user terminal device 100, which displays an order screen based on the created proposal information. The user terminal device 100 then displays an order screen containing multiple work plans (step ST108). The user terminal device 100 accepts the operation to select the target part 310 and the work plan selected by the user. Based on the accepted operation, the user terminal device 100 sends order information S108 to the maintenance support system 400.

[0047] Figure 9 shows an example of order information (order history information) in the 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. The work plan information may have different service fees depending on whether the user is a subscription member or a regular member who pays the fee at the same time as the maintenance work is decided. Option information includes, for example, whether or not there is work support equipment, parts to be replaced at the same time as the target part 310, work to be maintained at the same time, and parts that can be substituted for the target part 310. Order information may be stored in the storage unit 412 as order history.

[0048] 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 ST110), and transmits the order information S110 to the factory equipment 500 and the maintenance company equipment 600.

[0049] In the sequence described above, the proposal unit 406 creates proposal information that includes the work schedule and cost for a work plan that does not use the work support equipment (1), and the work schedule and cost for a work plan that uses the work support equipment (1), as shown in Figure 8, and that shortens the work schedule for the work plan that uses the work support equipment (1) compared to the work schedule for the work plan that does not use the work support equipment (1). The proposal unit 406 can also create proposal information that includes the number of work days and cost when the work support equipment 610 owned by the maintenance company is used as the work support equipment (1). The proposal unit 406 can also create proposal information that includes the number of work days and cost when the user's work support equipment 120 is used as the work support equipment (2), and the number of work days and cost when the maintenance company's work support equipment 610 is used as the work support equipment (2).

[0050] In the sequence described above, the notification unit 208 may notify the user terminal device 100 of part viewing information S100, which includes access information indicating an external site. The access information indicating an external site is the URL information of an external site managed by the maintenance support system 400. The user terminal device 100 displays the URL information of the external site using the display unit 102 and accepts an operation to select the URL information of the external site. As a result, the user terminal device 100 sends a viewing request including the URL information to the maintenance support system 400, and the maintenance support system 400 sends suggested information to the user terminal device 100. As a result, the user terminal device 100 can send order information to the external site indicated by the URL information, and the maintenance support system 400 can process the order for the target part 310 based on the order information.

[0051] Figure 10 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 a link with access information and parts viewing information. The user terminal device 100 displays the link contained in the received email on the display unit 102 using its email software. When 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 11 shows an example of an order screen in an embodiment. The order screen includes, for example, equipment information, maintenance information, an order request button, and a quote request button. The device information includes, for example, a message indicating that a target part 310 requiring replacement or maintenance has been estimated based on the sensing information of the target device 300, image information of the target part 310, and price information for the target part 310. The maintenance information includes a message indicating whether to select a maintenance plan that uses work support equipment or one that does not, the schedule and fees for each maintenance plan, and multiple buttons corresponding to each maintenance plan. When the user terminal device 100 selects the order request button while one of the multiple buttons corresponding to each maintenance plan is selected, it outputs the order information for the selected maintenance plan.

[0053] Figure 12 shows another example of the order screen in the embodiment. The order screen may include maintenance plan A and maintenance plan B, and may also include detailed information for each maintenance plan, an order request button for each maintenance plan, and a quote request button. Detailed information may include, for example, the work name, the delivery destination and work location of the target part 310, the work schedule, the number of workers, and the work support equipment. For example, maintenance plan A uses ○ units of the maintenance company's work support equipment ○○, and maintenance plan B uses △ units of the user's work support equipment △△.

[0054] As described above, according to the equipment maintenance system 1 of the embodiment, when creating a maintenance plan for a target component 310 estimated based on sensing information of the target equipment 300, if work support equipment is available, it can propose a work plan with a shorter work schedule and cost than the work schedule without work support equipment. Furthermore, according to the equipment maintenance system 1, it can notify the user of proposed information including the work schedule and cost for a work plan without work support equipment and the work schedule and cost for a work plan with work support equipment. Thus, according to the equipment maintenance system 1, it is possible to provide a choice of work schedules when replacing or maintaining the target component 310 of the target equipment 300.

[0055] (Second Embodiment) Figure 13 is a sequence diagram showing an example of the processing procedure of the equipment maintenance system 1 in the second embodiment. The user terminal device 100 may send a work support equipment request S120 to the maintenance support system 400 requesting the use of work support equipment 120, and the maintenance support system 400 may acquire the work support equipment request S120 by the acquisition unit 416. The work support equipment request S120 is information for calculating the work schedule and work charges, such as the manufacturer, part number, and schedule information of the work support equipment 120.

[0056] The work support equipment storage unit 414 stores information for calculating the duration of work on the target part 310 using the work support equipment 120 (first work support equipment) owned by the user of the target equipment 300, and information for calculating the duration of work on the target part 310 using the work support equipment 610 (second work support equipment) owned by the maintenance company. The proposal unit 406 can create proposal information including the work schedule and cost of a first work plan using the work support equipment 120, and the work schedule and cost of a second work plan using the work support equipment 610 (step ST106).

[0057] The equipment maintenance system 1 may obtain a work support equipment request S120 from the user terminal device 100, which includes the capabilities of the work support equipment 120 to be used for working on the target part 310. The capabilities of the work support equipment 120 are, for example, information for obtaining the period by which the work schedule can be shortened by using the work support equipment 120. The proposal unit 406 can then calculate the work schedule and work fee for the work plan when the work support equipment 120 is used, based on the capabilities of the work support equipment (step ST106).

[0058] The proposal unit 406 may set a weight parameter A for calculating the labor cost of a work plan using the work support device 120 to be greater than the weight parameter B for calculating the labor cost of a work plan using the work support device 610. The weight parameter is a coefficient for increasing or decreasing the labor cost, and the larger the coefficient, the greater the increase in the labor cost. That is, when the work support device 120 provided by the user is used, the proposal unit 406 multiplies the labor cost determined by the work support device 610 other than the work support device 120 provided by the user, and the work on the target equipment 300 and the target part 310, by the weight parameter A. Also, when the work support device 120 provided by the user is not used, the proposal unit 406 multiplies the labor cost determined by the work support device 610, and the work on the target equipment 300 and the target part 310, by the weight parameter B. In other words, the proposal unit 406 may create proposal information such that the work fee for a work plan using the work support device 120 is higher than the work fee for a work plan using the work support device 610 (step ST106).

[0059] According to the equipment maintenance system 1 of the second embodiment, the user can be provided with a choice of work plans by allowing them to view the work schedule and fees for a first work plan using the first work support equipment 120 owned by the user, and the work schedule and fees for a second work plan using the second work support equipment 610. Furthermore, according to the equipment maintenance system 1 of the second embodiment, the user terminal device can calculate the work schedule and work charges for a work plan when using the first work support equipment 120, based on work support equipment information including the capabilities of the first work support equipment 120 used for work on the target part 310. Therefore, it is possible to propose a work plan that is close to the work schedule and work charges when the user actually uses the first work support equipment 120 that they own. Furthermore, according to the equipment maintenance system 1 of the second embodiment, the weight parameters for calculating the work schedule and labor costs of a work plan using the first work support equipment 120 can be made larger than the weight parameters for calculating the work schedule and labor costs of a work plan using the second work support equipment 610. This makes it possible to charge higher labor costs when there is insufficient information on the capabilities, processes, quality, etc., of work support equipment other than the factory equipment 500.

[0060] Although various embodiments and modifications have been described, these are merely examples and are not limited to them. For example, one embodiment or modification, or a part of one embodiment or modification, may be combined with one or more other embodiments or modifications to realize one aspect of the present invention.
