A kind of UAV wireless charging system and its charging control method

Abstract

A wireless charging system for an unmanned aerial vehicle and a charging control method thereof. The system includes a ground platform end and a UAV end; the ground platform end includes a box body, a first communication module, a first control module, a power transmitting coil, a proximity sensor, an actuating mechanism and a shielding layer; the UAV end includes a UAV , the second communication module, the second control module, the power receiving coil, the voltage detection module, the UAV battery and the rectification circuit; the advantage of the present invention is that the voltage detection module is used to measure the voltage of the UAV battery in real time, and through the first and second The communication module and the first and second control modules effectively control the charging and discharging of the drone battery, which can prevent the drone battery from over-discharging and overcharging. The use of the actuating mechanism effectively solves the problem of concentric coupling of the power transmitting and receiving coil, thereby avoiding the problem of inaccurate positioning and landing of the drone, and at the same time improving the power transmission efficiency of the coil. The elastic snap ring plays the role of fixing the drone, avoiding the influence of external force during field operations.

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...

AI Technical Summary

Problems solved by technology

However, the accuracy level of UAV positioning is not high at present, relying on UAV autonomous positioning landing error is relatively large, the coupling effect between the receiving coil and the base station transmitting coil is not ideal, and the coupling cannot be accurately or even coupled, resulting in low charging efficiency
