The invention discloses an unmanned aerial vehicle energy charging system and method based on laser wireless energy transmission. The unmanned aerial vehicle energy charging system comprises an unmanned aerial vehicle system, a task load and a laser wireless energy transmission system. The laser wireless energy transmission system further comprises a ground vehicle-mounted transmitting system and an airborne receiving system. According to the invention, a high-energy laser beam is used as an energy carrier and is emitted by the collimation optical system, and light energy is converted into electric energy at a far end by utilizing the laser battery array, so that non-contact power supply for far-end electric equipment is realized, and the method is an effective means for long-distance wireless energy transmission. When the laser wireless energy transmission method is adopted to charge the unmanned aerial vehicle, a novel energy supply mode can be provided for the unmanned aerial vehicle, the endurance time is prolonged, and the use value is improved.
Description
technical field [0001] The invention relates to an unmanned aerial vehicle charging system and method based on laser wireless energy transmission, and belongs to the technical field of laser wireless energy transmission. Background technique [0002] UAVs are more and more widely used in military fields such as reconnaissance, electronic jamming, guidance, fixed-point attack, patrol and battlefield assessment, as well as civil fields such as aerial photography, disaster detection, weather detection, and urban traffic management. However, the current UAVs generally have insufficient endurance, and it is urgent to carry out research on advanced energy and power technology to achieve long endurance of UAVs. [0003] There are two working modes of laser wireless energy transfer drone: real-time charging and supplementary charging. [0004] Among them, the supplementary power supply only requires precise positioning and tracking of the drone during charging. This will greatly r...
