[0013] (Embodiment 1) An example of the configuration of the management device 10 will be described below with reference to Fig. 1. The management device 10 may be a computer device that operates when a processor executes a program stored in a memory. The management device 10 may be, for example, a server device.

[0014] The management device 10 includes an acquisition unit 11, a generation unit 12, and a communication unit 13. The acquisition unit 11, the generation unit 12, and the communication unit 13 may be software or modules that are executed by a processor executing a program stored in a memory. Alternatively, the acquisition unit 11, the generation unit 12, and the communication unit 13 may be hardware such as a circuit or a chip.

[0015] The acquisition unit 11 acquires location information of a worker inspecting a plurality of pieces of equipment. The acquisition unit 11 may be used as a means for acquiring location information. The equipment may be, for example, equipment installed in a substation or a power plant. The equipment may be, for example, a power transmission line, a transformer, a circuit breaker, etc. For example, a plurality of circuit breakers may exist in a substation, and the appearances of the respective circuit breakers may be similar to each other. Inspection may be performing maintenance work including checking the normality of the equipment, repairing it, replacing parts, etc.

[0016] The location information may be, for example, location information indicating the location of a communication terminal held by the worker. The location information may be, for example, information measured using a Global Positioning System (GPS). The acquisition unit 11 may receive the location information from the communication terminal held by the worker via a communication network. Alternatively, the location information of the worker may be identified using an image captured by a camera predetermined within the premises.

[0017] The generating unit 12 generates image data that highlights a first facility that the worker should inspect most closely among the facilities, and indicates the location information of the facilities and the worker. The generating unit 12 may be used as a means for generating image data. It is assumed that the worker inspects the facilities in order.

[0018] Among the multiple pieces of equipment, emphasizing the first equipment may mean that the first equipment is displayed in an emphasized manner when image data is displayed on a display unit such as a display. Emphasizing the first equipment may mean that the first equipment is displayed in a manner that distinguishes it from other equipment. For example, emphasizing the first equipment may mean that the first equipment is displayed in a color different from other equipment, or that the first equipment is displayed using a solid line and the other equipment is displayed using a dotted line. Alternatively, emphasizing the first equipment may mean that only the first equipment is displayed and the other equipment is not displayed. Alternatively, emphasizing the first equipment may mean that the first equipment is displayed in a flashing manner. Alternatively, emphasizing the first equipment may mean that a character or symbol is added to the first equipment and displayed.

[0019] The image data indicating the position information of the plurality of pieces of equipment and the worker may be, for example, data in which the position of the worker is reflected in map data indicating the arrangement of the plurality of pieces of equipment. In other words, the image data indicating the position information of the plurality of pieces of equipment and the worker may be map data indicating the position information of the plurality of pieces of equipment and the worker. The generation unit 12 may hold the position information of the equipment in advance. In other words, the generation unit 12 may generate map data indicating the arrangement of the plurality of pieces of equipment in advance, and reflect the position information of the worker acquired by the acquisition unit 11 in the map data.

[0020] The communication unit 13 transmits the image data to a communication terminal held by the worker. The communication unit 13 may be used as a means for transmitting image data. The communication unit 13 may transmit the image data to the communication terminal via a communication network. The communication terminal may be a portable computer device such as a smartphone terminal or a tablet terminal.

[0021] Next, the flow of communication processing executed in the management device will be described with reference to Fig. 2. First, the acquisition unit 11 acquires location information of a worker inspecting multiple pieces of equipment (S11). Next, the generation unit 12 emphasizes a first piece of equipment that the worker should inspect most soon among the multiple pieces of equipment, and generates image data showing the location information of the multiple pieces of equipment and the worker (S12). Next, the communication unit 13 transmits the image data to a communication terminal held by the worker (S13).

[0022] Next, a configuration example of the communication terminal 20 will be described with reference to Fig. 3. The communication terminal 20 may be a computer device that operates when a processor executes a program stored in a memory.

[0023] The communication terminal 20 has a transmitting unit 21, a receiving unit 22, and a display unit 23. The transmitting unit 21, the receiving unit 22, and the display unit 23 may be software or modules that are executed by a processor executing a program stored in a memory, or the transmitting unit 21, the receiving unit 22, and the display unit 23 may be hardware such as a circuit or a chip.

[0024] The transmission unit 21 transmits position information of a worker inspecting multiple pieces of equipment to the management device 10. The transmission unit 21 may be used as a means for transmitting position information. The position information of the worker may be, for example, position information indicating the position of the communication terminal 20. The position information of the communication terminal 20 may be, for example, information measured using a GPS. Alternatively, the transmission unit 21 may transmit position information of the worker acquired from a GPS device or the like held by the worker to the management device 10. The transmission unit 21 may transmit the position information of the worker to the management device 10 via a communication network.

[0025] The receiving unit 22 receives image data from the management device 10, in which a first facility that the worker should inspect most closely among the plurality of facilities is highlighted and which indicates the location information of the plurality of facilities and the worker. The receiving unit 22 may be used as a means for receiving image data. The receiving unit 22 may receive the image data from the management device 10 via a communication network.

[0026] The display unit 23 displays the image data. The display unit 23 may be used as a means for displaying the image data. The display unit 23 may be, for example, a display.

[0027] Next, the flow of communication processing executed in communication terminal 20 will be described with reference to Fig. 4. First, transmission unit 21 transmits position information of a worker inspecting multiple pieces of equipment to the management device (S21). Next, reception unit 22 receives image data from management device 10 in which a first piece of equipment that the worker should inspect most closely is highlighted, and which indicates the position information of the multiple pieces of equipment and the worker (S22). Next, display unit 23 displays the image data (S23).

[0028] As described above, the communication terminal 20 receives image data from the management device 10, in which a first facility among a plurality of facilities that the worker should inspect most closely is highlighted, and which indicates the location information of the plurality of facilities and the worker. The worker can ascertain the facility to be inspected and the worker's current location by checking the image data displayed on the communication terminal 20. This allows the worker to easily head to the facility to be inspected, even if there are a plurality of facilities with similar appearances, for example. The worker can efficiently perform the inspection work by heading to the first facility displayed on the communication terminal 20.

[0029] 1 and 3, an example has been described in which the management device 10 generates the drawing data and the communication terminal 20 receives the drawing data from the management device 10, but the communication terminal 20 may generate the drawing data. That is, the communication terminal 20 may have the generation unit 12 and generate the drawing data. In other words, the communication terminal 20 may generate image data that highlights a first facility that the worker should inspect in the near future and indicates location information of the plurality of facilities and the worker, without using the management device 10.

[0030] (Embodiment 2) Next, a configuration example of the management device 30 will be described with reference to Fig. 5. The management device 30 has a configuration in which a work information management unit 31 and a three-dimensional data management unit 32 are added to the management device 10. The work information management unit 31 and the three-dimensional data management unit 32 may be software or modules that perform processing by a processor executing a program stored in a memory. In the following explanation, detailed explanations of functions or operations similar to those of the management device 10 will be omitted.

[0031] The work information management unit 31 manages the work content, work procedure, and equipment to be worked on, etc., to be performed by the worker holding the communication terminal 20. The work information management unit 31 may be used as a means for managing the work content, etc. Managing the work content, work procedure, and equipment to be worked on, etc., may mean storing the work content, work procedure, and equipment to be worked on in a memory, etc. The work information management unit 31 manages the equipment to be worked on in association with the work content or work procedure to be performed in the equipment. An administrator, etc., who manages the management device 30, may input information regarding the work content or work procedure in each facility. Alternatively, the work information management unit 31 may acquire information regarding the work content or work procedure in each facility via a network from a server device, etc., which manages information regarding the work content or work procedure in each facility.

[0032] The three-dimensional data management unit 32 manages three-dimensional data in which a plurality of facilities are arranged. The three-dimensional data management unit 32 may be used as a means for managing the three-dimensional data. The three-dimensional data may be referred to as three-dimensional map data. The three-dimensional data may be, for example, point cloud data. That is, a plurality of facilities may be shown using the point cloud data. The point cloud data may be generated, for example, using a LiDAR (Light Detection And Ranging) device. The LiDAR device may be referred to as a laser scanner. The LiDAR device may be used as a device integrated with the management device 30, or may be connected to the management device 30 via a network. Alternatively, the point cloud data may be generated using a plurality of image data in which a plurality of facilities are shown. For example, the three-dimensional data may be data in which the facilities included in the plurality of image data are three-dimensionalized using SfM (Structure from Motion).

[0033] The three-dimensional data management unit 32 may manage the three-dimensional data in association with so-called world coordinates, which are expressed using latitude and longitude. The three-dimensional data management unit 32 converts the three-dimensional information of each point of the point cloud data into world coordinates. The three-dimensional data management unit 32 may manage position information of multiple pieces of equipment included in the three-dimensional data. Alternatively, the three-dimensional data management unit 32 may manage the three-dimensional data in association with coordinates specific to a measuring device for the three-dimensional data, such as a LiDAR device.

[0034] The generating unit 12 generates image data in which the position information of the communication terminal 20 acquired by the acquiring unit 11 is reflected in the three-dimensional data. For example, the generating unit 12 may reflect the position information of the communication terminal 20 measured using a GPS in the three-dimensional data associated with the world coordinates. Alternatively, the generating unit 12 may convert the position information of the communication terminal 20 measured using a GPS into coordinates specific to the measuring device of the three-dimensional data. In this case, the generating unit 12 may reflect the converted position information of the communication terminal 20 in the three-dimensional data associated with the coordinates specific to the measuring device of the three-dimensional data.

[0035] The image data indicates the position of the communication terminal 20 in three-dimensional data in which a plurality of pieces of equipment are arranged. Furthermore, the generation unit 12 updates the image data by using information managed in the work information management unit 31. Updating the image data may be rephrased as processing, editing, or changing the image data.

[0036] The work procedure managed by the work information management unit 31 defines the order of inspection of equipment. In this case, the generation unit 12 may specify the first equipment defined in the work procedure, or the equipment that has the earliest inspection order among the equipment not inspected by the worker holding the communication terminal 20, as the equipment that the worker should inspect most soon. The equipment that the worker should inspect most soon may be referred to as a priority inspection equipment hereinafter.

[0037] Alternatively, when the order of the equipment to be inspected is not determined, the generation unit 12 may specify the equipment that is closest to the location of the worker using the communication terminal 20 as the equipment to be inspected with priority.

[0038] Alternatively, when multiple pieces of equipment to be inspected are predetermined in the work procedure, the generating unit 12 may determine an order in which the worker efficiently inspects the multiple pieces of equipment. The order in which the worker efficiently inspects the multiple pieces of equipment may be, for example, an order in which the worker has to move the shortest distance. Alternatively, the order in which the worker efficiently inspects the multiple pieces of equipment may be an order in which two or more pieces of equipment performing similar work are inspected consecutively.

[0039] Alternatively, the generation unit 12 may specify the priority inspection equipment using a learning model for specifying the priority inspection equipment from among a plurality of pieces of equipment. The learning model may output the priority inspection equipment using, for example, the position of each piece of equipment, the position of the worker, the work procedure, etc. The learning model may be generated by machine learning or the like.

[0040] The generation unit 12 emphasizes the priority inspection equipment. For example, the generation unit 12 may reduce the amount of data for displaying equipment other than the priority inspection equipment compared to the amount of data for displaying the priority inspection equipment. For example, the generation unit 12 may display the priority inspection equipment using a solid line, whereas the generation unit 12 may display the equipment other than the priority inspection equipment using a dotted line. Alternatively, the generation unit 12 may increase the resolution for displaying the priority inspection equipment compared to the resolution for displaying the equipment other than the priority inspection equipment. The generation unit 12 may increase the resolution for the priority inspection equipment compared to the other equipment, thereby clearly displaying the priority inspection equipment.

[0041] Alternatively, the generation unit 12 may use a color for displaying the prioritized inspection equipment that is different from the color for displaying the other equipment. Alternatively, the generation unit 12 may display the prioritized inspection equipment in a flashing manner and the other equipment in a non-flash manner.

[0042] The generating unit 12 may further update the image data so as to include the work content or work procedure to be performed at the prioritized inspection equipment. For example, the generating unit 12 may generate image data so as to display the work content or work procedure at a position that does not overlap with the prioritized inspection equipment.

[0043] The communication unit 13 transmits the image data generated by the generation unit 12 to the communication terminal 20.

[0044] Here, the image data 40 displayed on the display unit 23 of the communication terminal 20 will be described with reference to Fig. 6. Fig. 6 shows the image data 40 generated by the generation unit 12. The image data 40 includes a prioritized piece of equipment for inspection 41, a number of other pieces of equipment 42, work content 43, and a worker 44. The other pieces of equipment 42 indicate equipment that is different from the prioritized piece of equipment for inspection 41. The image data 40 shows that the prioritized piece of equipment for inspection 41 is displayed with emphasis by displaying the prioritized piece of equipment for inspection 41 using a thick line and the other pieces of equipment 42 using a dotted line.

[0045] The worker 44 is a worker holding the communication terminal 20. The image data 40 shows that the worker 44 is present near the priority inspection equipment 41. The image data 40 shows that the work content 43 is displayed in an area different from the area where the priority inspection equipment 41, the other equipment 42, and the worker 44 are displayed. The dotted line in the image data 40 shows the boundary between the area where the work content 43 is displayed and the area where the priority inspection equipment 41, the other equipment 42, and the worker 44 are displayed. The dotted line showing the boundary is used to easily explain that the area where the work content 43 is displayed is distinguished from the area where the priority inspection equipment 41, the other equipment 42, and the worker 44 are displayed, so it does not have to be actually displayed on the display unit 23. Alternatively, the dotted line showing the boundary may actually be displayed on the display unit 23.

[0046] For example, when the worker 44 has completed all or part of the work displayed in the work content 43, the worker 44 may input information indicating the completion of the work to the communication terminal 20. The communication terminal 20 may transmit information indicating that the work to be performed at the prioritized inspection equipment 41 has been completed to the management device 30. When the management device 30 receives the information indicating that the work at the prioritized inspection equipment 41 has been completed, the management device 30 may update the image data and determine the next prioritized inspection equipment 41. The management device 30 transmits the updated image data to the communication terminal 20.

[0047] FIG. 7 shows image data 40 in which the priority inspection equipment 41 has been changed from FIG. 6. In the image data 40 in FIG. 7, the equipment that was the priority inspection equipment 41 in FIG. 6 has been updated to inspected equipment 45, and the equipment that was the other equipment 42 in FIG. 6 has been updated to the priority inspection equipment 41. Furthermore, the work content 43 may be changed to work content to be performed in the new priority inspection equipment 41. Furthermore, in FIG. 7, the inspected equipment 45 is displayed in the same way as the other equipment 42, but the inspected equipment 45 may be displayed to be distinguished from the other equipment 42. Alternatively, the inspected equipment 45 may not be displayed.

[0048] Next, the flow of communication processing executed in the management device 30 will be described with reference to Fig. 8. First, the generation unit 12 acquires three-dimensional data indicating the arrangement of a plurality of pieces of equipment from the work information management unit 31 (S31). Next, the generation unit 12 acquires position information of the worker from the acquisition unit 11 (S32). The position information of the worker may be position information of a communication terminal held by the worker.

[0049] Next, the generating unit 12 reflects the position information of the worker in the three-dimensional data (S33). Specifically, the generating unit 12 converts the three-dimensional positions of the point cloud data constituting the three-dimensional data into world coordinates. Furthermore, the generating unit 12 reflects the position information of the worker, which is positioned using a GPS or the like, in the three-dimensional data after conversion into world coordinates. Alternatively, the generating unit 12 may convert the position information of the worker, which is positioned using a GPS or the like, into coordinates specific to the measuring device of the point cloud data. In this case, the generating unit 12 may reflect the converted position information of the worker in the three-dimensional data associated with the coordinates specific to the measuring device of the point cloud data.

[0050] Next, the generation unit 12 determines the equipment that the worker should inspect most recently (priority inspection equipment) based on the work procedure and the worker's position information acquired from the work information management unit 31. Furthermore, the generation unit 12 generates image data that highlights and displays the determined equipment (S34). For example, the generation unit 12 may determine, as the priority inspection equipment, the equipment that is closest to the worker's position among multiple pieces of equipment that are subject to inspection in the work procedure. The generation unit 12 may highlight and display the equipment that should be inspected most recently by distinguishing the priority inspection equipment from other equipment.

[0051] Next, the communication unit 13 transmits the image data to the communication terminal 20 held by the worker (S35).

[0052] Next, the generation unit 12 determines whether or not the communication unit 13 has received a notification from the communication terminal 20 indicating that the inspection of the equipment (specifically, the equipment with priority for inspection) has been completed (S36). When the generation unit 12 determines that the communication unit 13 has received a notification from the communication terminal 20 indicating that the inspection of the equipment has been completed, the generation unit 12 determines whether or not there is any equipment that has not been inspected among the multiple pieces of equipment that are subject to inspection in the work procedure (S37). When the generation unit 12 receives a notification indicating that the inspection of the equipment has been completed, the generation unit 12 may manage the equipment that has been inspected as inspected equipment.

[0053] If the generation unit 12 determines that there is uninspected equipment, it repeats the process from step S32 onwards. If the generation unit 12 determines in step S36 that it has not received a notification from the communication terminal 20 indicating that the equipment inspection has been completed, it repeats the process of step S36. If the generation unit 12 determines in step S37 that there is no uninspected equipment, it ends the process.

[0054] As described above, the management device 30 identifies the equipment that the worker should inspect most closely among multiple pieces of equipment that the worker should inspect, based on the positions of the worker and the equipment. Furthermore, the management device 30 transmits image data that highlights the identified equipment to the communication terminal 20 held by the worker. The worker can recognize his / her own position and the equipment that should be inspected most closely by checking the image data displayed on the communication terminal 20. For example, even when inspecting multiple pieces of equipment that are similar in appearance, the worker can easily recognize the equipment that should be inspected most closely by checking the image data displayed on the communication terminal 20.

[0055] Furthermore, the management device 30 may generate image data emphasizing the equipment to be inspected soon by reducing the amount of data for displaying equipment other than the equipment to be inspected soon relative to the amount of data for displaying the equipment to be inspected soon. Reducing the amount of data may be reducing the resolution. This makes it possible to reduce the amount of image data processed by the communication terminal 20 compared to a case in which all equipment has the same data amount or resolution. As a result, even if the communication terminal 20 is a small device with poor processing capabilities, the image data can be displayed.

[0056] (Embodiment 3) Next, an example of image data generated by the generating unit 12 will be described with reference to Fig. 9. The generating unit 12 may identify an inspection route of the worker 44 and reflect the inspection route in the image data, as shown in Fig. 9. Fig. 9 shows the order in which the worker 44 inspects a plurality of pieces of equipment by connecting the pieces of equipment with arrows.

[0057] When multiple pieces of equipment to be inspected are predetermined in the work procedure, the generation unit 12 may determine an inspection route so that the worker can efficiently inspect the multiple pieces of equipment. The inspection route for the worker to efficiently inspect the multiple pieces of equipment may be, for example, a route that minimizes the distance traveled by the worker. Alternatively, the route for the worker to efficiently inspect the multiple pieces of equipment may be an order in which two or more pieces of equipment performing similar work are inspected consecutively.

[0058] The generation unit 12 may identify the priority inspection equipment using a learning model for identifying an inspection route. The learning model may output an inspection route using, for example, the location of each equipment, the location of the worker, the work procedure, etc. The learning model may be generated by machine learning or the like.

[0059] Next, the flow of the communication process executed in the management device 30 will be described with reference to Fig. 10. Steps S31 to S33 in Fig. 10 are similar to steps S31 to S33 in Fig. 8, and therefore detailed description thereof will be omitted.

[0060] After executing step S33, the generation unit 12 determines an inspection route for the worker and priority inspection equipment based on the work procedure and the worker's position information acquired from the work information management unit 31. Furthermore, the generation unit 12 generates image data that highlights and displays the determined inspection route and priority inspection equipment (S41).

[0061] Steps S35 to S37 performed after step S41 are similar to steps S35 to S37 in FIG. 8, and therefore a detailed description thereof will be omitted.

[0062] Here, in step S37, if the generation unit 12 determines that there is uninspected equipment, the processing from step S41 onwards is repeated. In step S41, the generation unit 12 generates image data in which the priority inspection equipment is changed according to the inspection route, as shown in Fig. 11. Changing the priority inspection equipment according to the inspection route may mean displaying the equipment to be inspected next after the inspected equipment as the equipment to be inspected soonest.

[0063] As described above, the management device 30 determines the equipment to be inspected in the near future as well as the inspection route. Since the inspection route is determined so as to shorten the travel distance, for example, the worker can perform the inspection efficiently by following the inspection route determined by the management device 30.

[0064] (Embodiment 4) Next, an example of image data generated by the generation unit 12 will be described with reference to Fig. 12. For example, when a worker 44 arrives at a priority inspection facility 41 and starts inspection, the generation unit 12 may generate image data 40 in which the display area of ​​the work content 43 is expanded as shown in Fig. 12. The display area of ​​the work content 43 in Fig. 12 is expanded more than the display area of ​​the work content 43 in Fig. 6 and the like.

[0065] The generating unit 12 may generate image data 40 shown in Fig. 12 when the position of the worker overlaps with the position of the prioritized inspection equipment 41, or when the distance between the position of the worker and the position of the prioritized inspection equipment 41 becomes shorter than a predetermined distance. The acquiring unit 11 periodically acquires position information from the communication terminal 20 held by the worker. The generating unit 12 may specify the distance between the worker and the prioritized inspection equipment 41 based on the position information of the worker acquired by the acquiring unit 11 and the position information of the equipment managed in the three-dimensional data managing unit 32.

[0066] 12 when receiving information indicating the start of work indicated in the work content 43 from the communication terminal 20. When the communication terminal 20 inputs information indicating the start of work indicated in the work content 43 from the worker, the communication terminal 20 may transmit the input information to the management device 30. For example, when the image data 40 before the display area of ​​the work content 43 is expanded is displayed on the display unit 23 of the communication terminal 20, the worker may input information indicating the start of work indicated in the work content 43 by touching the area of ​​the work content 43, for example.
