The first detection unit 64 is, for example, a sensor device for acquiring various sensing data such as a camera device and a microphone. The first inspection range is a range inspected by the unmanned aerial vehicle 60 including the power distribution pole 30 and the power distribution line L1. The first inspection range may be, for example, a range inspected near the power distribution pole 30 that cannot be inspected by the electronic device 34. The first information is first sensing data acquired by the unmanned aerial vehicle 60 for determining an abnormality in the imaging data or the like. The first communication unit 62 transmits the first information (first sensing data) detected by the first detection unit 64 to the electronic device 34.

[0022] The flight management system 50 includes, for example, a flight planning unit 52 and a flight control unit 54.

[0025] FIG. 7 is a diagram for explaining the operation of the unmanned aerial vehicle 60 and the electronic device 34 in the embodiment. First, the flight plan unit 52 transmits the position information of the support mechanism 38A and the position information of the support mechanism 38B to the unmanned aerial vehicle 60. The unmanned aerial vehicle 60 first moves to the vicinity of the support mechanism 38A to sense the range including the support mechanism 38A, and transmits the first sensing data to the electronic device 34A. The first sensing data obtained by sensing the range including the support mechanism 38A is transmitted from the unmanned aerial vehicle 60 to the electronic device 34A, and then transmitted from the electronic device 34A to the master station device 42. Next, the unmanned aerial vehicle 60 flies along the power distribution line L1 from the support mechanism 38A to the support mechanism 38B to acquire the first sensing data obtained by sensing the power distribution line L1 and the surroundings of the power distribution line L1. The unmanned aerial vehicle 60 flies along the power distribution line L1 by controlling the flight direction while recognizing the power distribution line L1 using, for example, video data. The unmanned aerial vehicle 60 senses an area including the support mechanism 38B and transmits first sensing data to the electronic device 34B. The first sensing data obtained by sensing the area including the power distribution line L1 from the support mechanism 38A to the support mechanism 38B, the surroundings of the power distribution line L1, and the support mechanism 38B is transmitted from the unmanned aerial vehicle 60 to the electronic device 34B, and then transmitted from the electronic device 34B to the master station device 42. This allows the master station device 42 to obtain the first sensing data including the electronic device 34A, the power distribution line L1, and the support mechanism 38B, and to determine an abnormality based on the obtained first sensing data, which can be confirmed by the operator.

[0026] The first inspection range may be a range based on weather information (forecast, rainfall, wind speed, and wind direction). The weather information is, for example, information that indicates a weather forecast, rainfall, wind speed, or wind direction. The flight planning unit 52 acquires weather information, for example, from an information providing device (not shown) via a communication network NW. The flight planning unit 52 determines the first inspection range based on weather information that indicates, for example, an area with heavy rainfall, and creates a flight plan. This allows the unmanned aerial vehicle 60 to acquire first sensing data around the support mechanism 38 and the power distribution line L1 in the area with heavy rainfall, and transmit the acquired first sensing data to the master station device 42 via the electronic device 34.

[0027] FIG. 8 is a block diagram showing another example of the inspection support system 1 according to the embodiment. The electronic device 34 may include an arrival port 35 of the unmanned aerial vehicle 60 shown in FIG. 4 , and a charging unit 343a that charges the unmanned aerial vehicle 60 that has arrived at the arrival port 35 using power transmitted and distributed by a power transmission and distribution facility. The power transmission and distribution facility is the substation / power distribution tower system 20, the power distribution pole 30, and the power distribution line L1 included in the power distribution system. The charging unit 343a has a charging mechanism that corresponds to the charging method of the unmanned aerial vehicle 60. The charging mechanism may include, for example, a transformer that converts the transmitted and distributed power into charging power for the unmanned aerial vehicle 60, and a mechanism that wirelessly charges the unmanned aerial vehicle 60 that has arrived at the arrival port 35.

[0028] The first detection unit 64 detects second information related to an abnormality in the power distribution line L1 or the support mechanism 38 detected upon arrival at the arrival port 35. The second information is sensing data related to the abnormality in the power transmission and distribution equipment detected upon arrival at the arrival port 35. Hereinafter, the sensing data related to the abnormality in the power transmission and distribution equipment detected upon arrival at the arrival port 35 will be referred to as second sensing data. The third communication unit 342 transmits the first sensing data and the second sensing data received from the unmanned aerial vehicle 60 to an external device (parent station device 42).

[0029] The operation of the unmanned aerial vehicle 60 and the electronic device 34 will be described with reference to FIG. 7. First, the flight plan unit 52 transmits the position information of the support mechanism 38A and the position information of the support mechanism 38B to the unmanned aerial vehicle 60. The unmanned aerial vehicle 60 first senses the range including the support mechanism 38A while moving to the arrival port 35 of the support mechanism 38A, and transmits the second sensing data to the electronic device 34A. The second sensing data obtained by sensing the range including the support mechanism 38A is transmitted from the unmanned aerial vehicle 60 to the electronic device 34A, and then transmitted from the electronic device 34A to the master station device 42. Next, the unmanned aerial vehicle 60 flies along the power distribution line L1 from the support mechanism 38A to the support mechanism 38B to acquire the first sensing data obtained by sensing the power distribution line L1 and the surroundings of the power distribution line L1. When the unmanned aerial vehicle 60 arrives at the arrival port 35 of the support mechanism 38B, it senses the range including the support mechanism 38B to obtain second sensing data, and transmits the first sensing data and the second sensing data to the electronic device 34B. The first sensing data obtained by sensing the distribution line L1 and the periphery of the distribution line L1, and the second sensing data obtained at the arrival port 35 of the electronic device 34B are transmitted from the unmanned aerial vehicle 60 to the electronic device 34B, and then transmitted from the electronic device 34B to the master station device 42. As a result, the master station device 42 can obtain the first sensing data and the second sensing data including the electronic device 34A, the distribution line L1, and the support mechanism 38B, and can determine an abnormality based on the obtained first sensing data and second sensing data, and can have the operator confirm it.

The electronic device 34 may include a second detection unit 343b that detects third information related to an abnormality of the electric power distribution line L1 or the support mechanism 38 in a second inspection range different from the first inspection range. The inspection ranges being different includes the inspection ranges not overlapping with each other and the inspection ranges not overlapping with each other. The second detection unit 343b is, for example, a sensor device for acquiring various sensing data such as a camera device and a microphone, and acquires sensing data to determine an abnormality. The second inspection range is a range inspected by the electronic device 34 including the support mechanism 38 and the electric power distribution line L1. The second inspection range may be, for example, a range inspectable from the position of the electronic device 34 among the ranges inspected near the electric power distribution pole 30. The third information is third sensing data acquired by the second detection unit 343b for determining an abnormality such as imaging data. The third communication unit 342 transmits the first sensing data received from the unmanned aerial vehicle 60 and the third sensing data detected by the second detection unit 343b to the master station device 42 serving as an external device.

[0031] FIG. 10 is another diagram for explaining the operation of the unmanned aerial vehicle 60 and the electronic device 34 in the embodiment. In FIG. 10, the first inspection range and the second inspection range do not overlap, but the present invention is not limited to this, and they may overlap partially. First, the flight plan unit 52 transmits the position information of the support mechanism 38A and the position information of the support mechanism 38B to the unmanned aerial vehicle 60. The second detection unit 343b of the electronic device 34A senses the second inspection range including the support mechanism 38A and acquires third sensing data. The third sensing data obtained by sensing the range including the support mechanism 38A is transmitted from the electronic device 34A to the master station device 42. The unmanned aerial vehicle 60 flies along the power distribution line L1 from near the support mechanism 38A to the support mechanism 38B to acquire first sensing data obtained by sensing the power distribution line L1 and the surroundings of the power distribution line L1. The first sensing data is transmitted from the unmanned aerial vehicle 60 to the electronic device 34B. The second detection unit 343b of the electronic device 34B senses the second inspection range including the support mechanism 38B and acquires third sensing data. The first sensing data and the third sensing data obtained by sensing the second inspection range including the support mechanism 38B are transmitted from the electronic device 34B to the master station device 42. This allows the master station device 42 to acquire the first sensing data and the third sensing data, and to determine an abnormality based on the acquired first sensing data and third sensing data, allowing the operator to confirm the abnormality.

[0032] FIG. 11 is another diagram for explaining the operation of the unmanned aerial vehicle 60 and the electronic device 34 in the embodiment. The second detection unit 343b may detect the third sensing data through a first angle based on the position where the electronic device 34A is installed, and the first detection unit 64 may detect the first sensing data through the power distribution line L1 at a second angle different from the first angle.

The power transmission determination unit 343c determines an abnormality in the transmitted and distributed power based on a change in the voltage value or current value supplied through the power distribution line L1. The electronic device 34 transmits the determination result to the master station device 42 in response to the abnormality being determined by the power transmission determination unit 343c. The master station device 42 transmits the position information, etc. of the electronic device 34 that has determined the abnormality to the flight management system 50. The flight plan unit 52 creates a flight plan for moving the unmanned aerial vehicle 60 to the first inspection range based on the position information of the electronic device 34.

[0034] The electronic device 34 may include an equipment abnormality determination unit 343d that determines an abnormality in at least one of the power distribution line L1 and the support mechanism 38 based on the first sensing data and the second sensing data. The equipment abnormality determination unit 343d is realized by, for example, a processor such as a CPU executing a program stored in a program memory.

The electronic device 34 transmits a determination result to the master station device 42 in response to the abnormality determined by the equipment abnormality determination unit 343d. This allows the master station device 42 to allow an operator to check the position and sensing data of the electronic device 34.

[0035] As described above, according to the embodiment of the inspection support system 1, the unmanned aerial vehicle 60 includes a first detection unit 64 that detects first information related to an abnormality in the power distribution line L1 or the support mechanism 38 in response to the unmanned aerial vehicle 60 moving to the first inspection range, and transmits the first information to the electronic device 34, which can transmit the first information to the master station device 42.
