The system is characterized by flexibility, good stability, easy manipulation, and real-time and accurate transmission. This paper designs a transmission line UAV AI inspection UV discharge system, which is composed of a mobile monitoring station, several UAV aircraft and background host computer. The system uses cameras, infrared devices, and other methods of automatic navigation or manual directional control to collect information on the transmission line and transmit it to the mobile monitoring station and the background host computer in real time. Technicians can grasp the operation of transmission lines in real time and eliminate operational defects and safety hazards in a timely manner.
