[0011] (Summary of the Disclosure) The work support system will be outlined below. As shown in FIG.

[0012] The extraction means 101 extracts at least one piece of work support information from a work support information database that stores a plurality of pieces of work support information, according to extraction conditions.

[0013] The transmission means 102 transmits at least one piece of work support information extracted by the extraction means to the augmented reality device.

[0014] The extraction condition is at least one of the following: the skill level of the worker who uses the augmented reality device, the weather history at the work site, the creation date of the work support information, and the information sender of the work support information.

[0015] According to the above configuration, it is possible to provide optimized work support information to a worker carrying an augmented reality device.

[0016] (First embodiment) Next, a first embodiment of the present disclosure will be described. Fig. 2 is an overall schematic diagram of a work support system 1. As shown in Fig. 2, the work support system 1 includes a work support server 2, an input device 3, and an augmented reality device 4.

[0017] The work support server 2 and the input device 3 are configured to be capable of two-way communication via a WAN 5 (Wide Area Network) such as the Internet. The work support server 2 and the augmented reality device 4 are similarly configured to be capable of two-way communication via the WAN 5. The input device 3 and the augmented reality device 4 may be configured to be capable of two-way communication via a LAN (Local Area Network). The work support server 2 is realized by a single device. However, instead of this, the work support server 2 may be realized by distributed processing by multiple devices. The input device 3 is realized by a single device. However, instead of this, the input device 3 may be realized by distributed processing by multiple devices.

[0018] A worker performs work at a work site while obtaining various information in real time from the augmented reality device 4. The work site is, for example, a substation. The worker performs maintenance and inspection of various equipment at the substation. The various equipment includes, for example, a transformer, a circuit breaker, a disconnecting switch, an instrument transformer, and a lightning arrester.

[0019] FIG. 3 is a block diagram of the work support server 2. As shown in FIG. 3, the work support server 2 has a processor 2a, a memory 2b, and a communication interface 2c. The processor 2a can access the memory 2b. The processor 2a communicates with the input device 3 and the augmented reality device 4 via the communication interface 2c. The processor 2a reads and executes a program stored in the memory 2b. As a result, the program causes hardware such as the processor 2a, the memory 2b, and the communication interface 2c to function as an extraction condition setting unit 10, an extraction unit 11, and a transmission unit 12. The memory 2b functions as a work support information database storage unit 13.

[0020] The work support information database storage unit 13 stores the work support information database. Fig. 4 shows an example of the data structure of the work support information database. As shown in Fig. 4, the work support information database associates "facility ID", "work support information ID", "proficiency level", "seismic intensity", "typhoon", "lightning strike", "information sender ID", and "information creation date" with each other.

[0021] The "facility ID" is facility identification information that identifies a facility. The "work support information ID" is work support information identification information that identifies work support information. The work support information is typically at least one of a manual (work process information) of work performed by a worker in the corresponding facility, a history of past troubles in the corresponding facility, and comments from a skilled worker. The "proficiency level" is proficiency level information that indicates the proficiency level of a worker. The proficiency level of a worker is typically expressed in five stages. For example, if a worker is a skilled worker, the proficiency level of the worker is "5". For example, if a worker is an inexperienced worker, the proficiency level of the worker is "1". The "seismic intensity" is seismic intensity information that indicates the seismic intensity of an earthquake. The "typhoon" is typhoon information that indicates the presence or absence of a typhoon. The "lightning strike" is lightning strike information that indicates the presence or absence of a lightning strike. The "information sender ID" is creator identification information that identifies the person who created the corresponding work support information. The "information creation date" is creation date information that indicates the creation date of the corresponding work support information.

[0022] Some work support information may include outline work support information and detailed work support information. When a highly skilled worker engages in a task, detailed work support information may be sufficient without requiring detailed work support information. On the other hand, when an inexperienced worker engages in a task, detailed work support information may be required. Some work support information may be work process information. In this case, the work process information may include outline work process information and detailed work process information. The outline work process information is a specific example of the first work process information. The detailed work process information is a specific example of the second work process information. The detailed work support information is more specific than the outline work support information. When a task is composed of multiple tasks, the outline work process information is composed only of the titles of the multiple tasks. In contrast, the detailed work process information may include detailed implementation guidelines for each task in addition to the titles of the multiple tasks.

[0023] The extraction condition setting unit 10 sets extraction conditions for extracting at least one piece of work support information from the work support information database shown in Fig. 4. The extraction condition setting unit 10 receives work-related information from the input device 3. The extraction condition setting unit 10 sets extraction conditions based on the work-related information.

[0024] The work-related information typically includes a facility ID, a worker's proficiency, and a work date. In this case, the extraction condition setting unit 10 sets the facility ID as a first extraction condition. The extraction condition setting unit 10 sets the second extraction condition as a worker's proficiency that is higher than the worker's proficiency indicated by the work-related information.

[0025] The extraction condition setting unit 10 accesses a weather database (not shown) to acquire disaster history for the seven days prior to the work date in the facility corresponding to the facility ID. If an earthquake has occurred in the facility within the seven days prior to the work date, the extraction condition setting unit 10 sets the seismic intensity of the earthquake as the third extraction condition. For example, if an earthquake with a seismic intensity of 5 has occurred in the facility within the seven days prior to the work date, the extraction condition setting unit 10 sets the third extraction condition to extract work support information with a "seismic intensity" of 5 or more. This makes it possible to extract work support information related to equipment that should be inspected with priority when a relatively large earthquake occurs.

[0026] Furthermore, the extraction condition setting unit 10 sets a fourth extraction condition so that, if a typhoon has occurred in the facility within 7 days prior to the work date, work support information in the work support information database where "typhoon" is 1 is extracted. This makes it possible to extract work support information related to facilities that should be inspected with priority when a typhoon occurs.

[0027] Furthermore, the extraction condition setting unit 10 sets a fifth extraction condition so that, if lightning has occurred in the facility within 7 days prior to the work date, work support information in which "lightning" in the work support information database is set to 1 is extracted. This makes it possible to extract work support information related to equipment that should be inspected with priority when lightning occurs.

[0028] The extraction condition setting unit 10 may set a sixth extraction condition using the information sender ID as a key, thereby making it possible to extract work support information sent by a person important to the facility.

[0029] The extraction condition setting unit 10 may set a seventh extraction condition so as to extract work support information whose information creation date is a predetermined number of years prior to the work date or later. This makes it possible to exclude work support information that is too old from the extraction targets.

[0030] The extraction unit 11 extracts at least one piece of work support information from the work support information database according to at least a first extraction condition. The extraction unit 11 extracts at least one piece of work support information from the work support information database according to at least one extraction condition set by the extraction condition setting unit 10 in addition to the first extraction condition. The at least one extraction condition is at least one of the second to seventh extraction conditions described above.

[0031] The transmission unit 12 transmits at least one piece of work support information extracted by the extraction unit 11 to the augmented reality device 4.

[0032] FIG. 5 is a block diagram of the input device 3. As shown in FIG. 5, the input device 3 has a processor 3a, a memory 3b, a communication interface 3c, an LCD 3d (Liquid Crystal Display), and an input interface 3e. The processor 3a can access the memory 3b. The processor 3a communicates with the work support server 2 and the augmented reality device 4 via the communication interface 3c. The processor 3a reads and executes a program stored in the memory 3b. As a result, the program causes the hardware such as the processor 3a, the memory 3b, the communication interface 3c, the LCD 3d, and the input interface 3e to function as a work-related information receiving unit 20 and a work-related information transmitting unit 21.

[0033] The work-related information receiving unit 20 receives the work-related information input via the input interface 3e. As described above, the work-related information typically includes a facility ID, a worker's skill level, and a work date.

[0034] The work-related information transmitting unit 21 transmits the work-related information accepted by the work-related information accepting unit 20 to the work support server 2.

[0035] FIG. 6 is a block diagram of the augmented reality device 4. The augmented reality device 4 is an electronic device to which an augmented reality function can be applied, and is typically a smartphone, a tablet, or smart glasses. In this embodiment, a case where the augmented reality device 4 is smart glasses will be described. The augmented reality device 4 has a processor 4a, a memory 4b, a communication interface 4c, a retinal projection type HMD 4d (Head Mounted Display), and a camera 4e. The processor 4a can access the memory 4b. The processor 4a communicates with the work support server 2 and the input device 3 via the communication interface 4c. The processor 4a reads and executes a program stored in the memory 4b. As a result, the program causes hardware such as the processor 4a, the memory 4b, the communication interface 4c, the HMD 4d, and the camera 4e to function as a work support information receiving unit 30, a deviation determining unit 31, and a display control unit 32. The camera 4e captures an image of the front of the worker wearing the augmented reality device 4.

[0036] The work support information receiving unit 30 receives at least one piece of work support information from the work support server 2.

[0037] The deviation determination unit 31 monitors the work of the worker to determine whether the work of the worker deviates from a specified work process. The deviation determination unit 31 typically monitors the work of the worker based on a camera image output from the camera 4e. Specifically, the deviation determination unit 31 monitors the work of the worker by identifying the equipment on which the worker is working, and the parts and tools handled by the worker based on a QR code (registered trademark) attached to the equipment, parts, and tools reflected in the camera image. Alternatively, the deviation determination unit 31 may identify the equipment on which the worker is working, and the parts and tools handled by the worker by identifying the equipment, parts, and tools reflected in the camera image using a known object detection technology. Typical examples of the object detection technology include R-CNN (Regions with Convolutional Neural Networks) and YOLO (You Look Only Once).

[0038] The display control unit 32 displays at least one piece of work support information on the HMD 4d. When the work support information includes outline work process information and detailed work process information, the display control unit 32 displays the outline work process information or the detailed work process information based on the determination result by the deviation determination unit 31. Specifically, when the work performed by the worker does not deviate from the work process defined by the detailed work process information, the display control unit 32 displays the outline work process information on the HMD 4d and does not display the detailed work support information on the HMD 4d. On the other hand, when the work performed by the worker deviates from the work process defined by the detailed work process information, the display control unit 32 displays the detailed work process information on the HMD 4d. In this case, the display control unit 32 may display the detailed work process information on the HMD 4d instead of the outline work process information, or may display the detailed work process information on the HMD 4d in addition to the outline work process information.

[0039] Next, the control flow of the work support system 1 will be described with reference to FIG.

[0040] S100: First, the work-related information receiving unit 20 of the input device 3 receives the work-related information input via the input interface 3e. As described above, the work-related information typically includes a facility ID, a worker's proficiency level, and a work date.

[0041] S110: Next, the work-related information transmitting unit 21 of the input device 3 transmits the work-related information accepted by the work-related information accepting unit 20 to the work support server 2. The extraction condition setting unit 10 of the work support server 2 receives the work-related information from the input device 3.

[0042] S120: Next, the extraction condition setting unit 10 of the work support server 2 sets extraction conditions based on the work-related information received from the input device 3.

[0043] S130: Next, the extraction unit 11 of the work support server 2 extracts at least one piece of work support information from the work support information database in accordance with the extraction conditions set by the extraction condition setting unit 10.

[0044] S140: Next, the transmission unit 12 of the work support server 2 transmits at least one piece of work support information extracted by the extraction unit 11 to the augmented reality device 4. The work support information reception unit 30 of the augmented reality device 4 receives at least one piece of work support information from the work support server 2.

[0045] S150: Next, the display control unit 32 of the augmented reality device 4 displays, on the HMD 4d, at least one piece of work support information received by the work support information receiving unit 30. Specifically, when the work support information includes outline work process information and detailed work process information, the display control unit 32 first displays the outline work process information on the HMD 4d.

[0046] S160: Next, the deviation determination unit 31 of the augmented reality device 4 determines whether or not the work performed by the worker deviates from the work process defined by the detailed work process information.

[0047] S170: In S160, if the deviation determination unit 31 of the augmented reality device 4 determines that the work by the worker deviates from the work process defined by the detailed work process information, the display control unit 32 of the augmented reality device 4 displays the detailed work process information on the HMD 4d instead of or in addition to the outline work process information, and ends the process. On the other hand, in S160, if the deviation determination unit 31 of the augmented reality device 4 determines that the work by the worker does not deviate from the work process defined by the detailed work process information, the display control unit 32 of the augmented reality device 4 ends the process.

[0048] The first embodiment has been described above. The above embodiment has the following features.

[0049] The work support server 2 (work support system) includes an extraction unit 11 and a transmission unit 12. The extraction unit 11 extracts at least one piece of work support information from a work support information database that stores a plurality of pieces of work support information, in accordance with extraction conditions. The transmission unit 12 transmits at least one piece of work support information extracted by the extraction unit 11 to the augmented reality device 4. The extraction conditions are at least one of the proficiency level of a worker using the augmented reality device 4, the weather history at the work site, the creation date of the work support information, and the information sender of the work support information. With the above configuration, optimized work support information can be provided to a worker carrying the augmented reality device.

[0050] When the extraction condition is a weather history, the weather history is a history of disasters that occurred at the work site before the work day. According to the above configuration, it is possible to provide work support information corresponding to past disasters to a worker carrying an augmented reality device.

[0051] The disaster is any one of an earthquake, a typhoon, and a lightning strike. According to the above configuration, it is possible to provide a worker carrying an augmented reality device with work support information corresponding to any one of past earthquakes, typhoons, and lightning strikes.

[0052] If the disaster is an earthquake, the extraction unit 11 extracts at least one piece of work support information according to the seismic intensity of the earthquake. With the above configuration, it is possible to provide a worker carrying an augmented reality device with work support information according to the seismic intensity of past earthquakes.

[0053] At least one piece of work support information includes outline work process information (first work process information) and detailed work process information (second work process information that is more specific than the first work process information). The augmented reality device 4 includes a deviation determination unit 31 and a display control unit 32. The deviation determination unit 31 determines whether or not the work performed by the worker deviates from the work process defined by the detailed work process information. The display control unit 32 displays the outline work process information or the detailed work process information based on the determination result of the deviation determination unit 31. With the above configuration, it is possible to display optimal work support information according to the status of the work performed by the worker.

[0054] If the work performed by the worker does not deviate from the work process defined by the detailed work process information, the display control unit 32 displays the outline work process information and does not display the detailed work process information. If the work performed by the worker deviates from the work process defined by the detailed work process information, the display control unit 32 displays the detailed work process information instead of or in addition to the outline work process information. With the above configuration, it is possible to display optimal work support information according to the status of the work performed by the worker. In other words, the display control unit 32 minimizes the amount of information displayed, and displays only the necessary information as necessary.
