Problems solved by technology

[0002] In the existing power system monitoring, unmanned aerial vehicles are widely used because of their flexible maneuverability, quick response, wide field of view, and various functions; the Chinese invention patent with the announcement number CN108828399B discloses a remote automatic fault monitoring for power transmission lines system, the operating mode of the system is: line protection action - the protection device sends the fault distance measurement to the protocol converter - the protocol converter converts the fault distance measurement data into UAV radio data transmission data and sends it to the UAV monitoring platform ——The UAV starts to fly to the fault point to collect and collect the fault situation of the transmission line—the fault situation is sent to the operation and maintenance department of the power supply company—the operation and maintenance department organizes the elimination of faults, thereby reducing the maintenance and operation cost of the power transmission line and shortening the time However, in the actual application process, if a small UAV is used, the control and data transmission distance is only 5-7 kilometers, and it is easy to be interfered by buildings, etc., and the flight time provided by the battery is less than half an hour. UAVs are used to send back fault conditions, and small-scale flight applications must be guaranteed, and there is a large distance limit. If a large-scale UAV is used, it will not only increase the cost of use and maintenance, but also be too large, and it will be difficult to fly in the city. Restricted by app
