The invention discloses a wireless laser charging method and system based on an unmanned aerial vehicle, and relates to the technical field of unmanned aerial vehicle charging, and the method comprises the steps: enabling a divergent light beam to be collimated into a parallel light beam through a laser transmitting device, and enlarging the diameter of an input light beam; a laser charging signal is converted into electric energy through a photovoltaic array, and meanwhile, the unmanned aerial vehicle is charged through a constant-current circuit; current and voltage in the charging process are monitored in real time through charging control, and whether charging current needs to be adjusted or not is judged according to monitored data. The wireless unmanned aerial vehicle is charged without being connected with a power line, and the central position of the light spot of the battery panel is judged by comparing the intensity of the laser light source with the output voltage of the photoresistor, so that the accurate control of the charging process is realized, and the problems of energy waste and battery overcharge in the charging process are avoided; and meanwhile, a constant-current circuit is adopted to charge the unmanned aerial vehicle, so that the hidden danger of battery short circuit caused by overcharging is avoided, and the charging stability and safety of the unmanned aerial vehicle are ensured.

    本发明公开了一种基于无人机的无线激光充电方法及系统,涉及无人机充电技术领域,包括通过激光器发射装置将发散的光束准直成平行光束,并将输入光束的直径扩大;通过光伏列阵将激光充电信号转换为电能,同时通过恒流电路对无人机进行充电;通过充电控制实时监测充电过程中的电流和电压,并根据监测的数据判断是否需要调节充电电流。本发明无需连接电源线无线无人机充电,通过对比激光光源的强度和光敏电阻的输出电压,判断电池板光斑的中心位置,从而实现对充电过程的精确控制,避免充电过程中的能量浪费和电池过度充电的问题,同时采用恒流电路对无人机进行充电,避免因过度充电而导致的电池短路隐患,从而确保无人机充电的稳定性和安全性。
