Abstract

The invention discloses an automatic tracking unmanned aerial vehicle laser charging device and a tracking method. The device comprises a laser transmitting end and a laser receiving end; a plurality of laser tubes are uniformly distributed in the laser transmitting end in the circumferential direction, each laser tube is correspondingly provided with a condensing mirror, multiple paths of laser can be reflected and converged by the condensing mirrors to reach a beam concentration unit, and laser beams are emitted by the beam concentration unit; a beam expander and a gallium arsenide array are arranged in the laser receiving end, and the beam expander is used for amplifying the diameter of the received laser beam and enabling the gallium arsenide array to convert light energy into electric energy. The problem of low integration level of the device can be solved, high-precision laser tracking is realized, and the energy conversion rate is effectively improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, and relates to an automatic tracking unmanned aerial vehicle laser charging device and a tracking method. Background technique [0002] With the development of science and technology, unmanned aerial vehicles (UAVs) gradually enter the civilian field, but the disadvantages of short battery life of UAVs are also exposed. If the battery capacity is increased, the load of UAVs will be increased. Human-machine flexibility. If the UAV can be continuously charged during the flight, the battery life will be greatly improved. At present, the most promising high-altitude long-endurance UAV is a solar-powered UAV. However, due to the instability of solar irradiation, the endurance time of solar-powered drones is limited. In order to further prolong the battery life of drones, it will be a new solution to use laser instead of sunlight to wirelessly charge drones remotely. [0003] Althou...
