Abstract

The invention relates to a wireless charging system of an unmanned aerial vehicle and a charging control method thereof. The system includes ground platform end and unmanned aerial vehicle end. The ground platform end comprises a box, a first communication module, a first control module, an electric energy transmitting coil, a proximity sensor, an actuating mechanism and a shielding layer. The UAVterminal comprises an UAV, a second communication module, a second control module, an electric energy receiving coil, a voltage detecting module, a UAV battery and a rectifying circuit. The inventionhas the advantages that the voltage detection module is utilized to measure the voltage of the battery of the unmanned aerial vehicle in real time, the charging and discharging of the battery of theunmanned aerial vehicle is effectively controlled through the first and second communication modules and the first and second control modules, and the overcharging of the battery of the unmanned aerial vehicle can be prevented. The problem of concentric coupling of power transceiver coil is solved effectively by using actuator, which avoids the problem of inaccurate positioning and landing of UAV,and improves the efficiency of power transmission of coil. The elastic snap ring plays the role of fixing the UAV and avoids the influence of external force during field operation.

Description

technical field [0001] The invention belongs to the technical field of wireless charging, and in particular relates to a wireless charging system for an unmanned aerial vehicle and a charging control method thereof. Background technique [0002] UAVs have been more and more widely used in the civilian field due to their low cost, high cost-effectiveness ratio, strong survivability, good maneuverability, and convenient use. However, as the power source of drones, their battery life has always been an urgent problem in the industry. Due to the limitation of battery technology level, short battery life is a major technical problem faced by current drones. Wireless charging technology solves this problem well. The current relatively mature solution is magnetic coupling wireless charging, which is composed of transceiver coils. The drone is equipped with a receiving coil, and the ground base station is equipped with a charging coil. However, the accuracy level of UAV positionin...
