用于边境巡逻的定点式多旋翼无人机无线充电系统设计

Aiming at the problems of insufficient endurance and limited cruising range of unmanned aerial vehicle (UAV) in border patrol, a charging scheme for autonomous entry of UAV in border patrol was proposed, which provides guarantee for UAV to perform long-distance border patrol tasks. The power supply and auxiliary deviation correction system of relay power supply station was designed. The UAV automatically aligns after landing, and the power supply system was turned on to charge. The UAV airborne power receiving and charging system was designed to effectively receive the transmitted power and convert it into controllable constant current and constant voltage energy flow to the airborne battery. A miniature experimental prototype was built. The test results show that the auxiliary alignment system can achieve accurate alignment of the UAV. The wireless charging system realizes 71. 3 W energy transmission, and the corresponding charging efficiency of the whole machine is 84. 6% . The airborne power receiving mechanism only weighs 28 g.
