Investigation on Intelligent Drone-Mounted Mobile Vehicle for Power Transmission Line Inspection

To address the problem of low efficiency of real-time data transmission in areas without signals in the process of transmission lines inspection, the drone-mounted mobile operation platform is investigated. A power supply scheme for the platform is developed. A communication system based on 5G plus BeiDou satellite and its deployment scheme are proposed, which turns from single communication method to dual communication method. When the 5G signal is good, the data transmission is achieved through the 5G network; when the 5G network link fails, the satellite communication system starts to work. The autonomous flight performance of drone on the mobile operating platform is tested. The results show that the drone has good take-off performance. The high-precision positioning of drone for transmission line inspection can be met using the real time kinematic (RTK) positioning technique. The landing accuracy of drone based on image recognition is high, and the flight stability of drone is good.
