High-altitude non-contact energy supply system and method for UAV

Abstract

The invention provides an unmanned aerial vehicle high-altitude non-contact type energy supply system and method. The method includes the steps that an aerial charging aircraft carrier receives a charging request sent by an unmanned aerial vehicle; position information of the unmanned aerial vehicle is obtained, and the relative position of the aerial charging aircraft carrier and the unmanned aerial vehicle is adjusted according to the position information; and electric energy is converted into electromagnetic energy which is wirelessly sent to the unmanned aerial vehicle. The problem existing in unmanned aerial vehicle energy supply on special occasions that no ground fixed charging station is available and the unmanned aerial vehicle is not allowed to land is solved, in the mode that the electric unmanned aerial vehicle and the aerial charging aircraft carrier are combined, the unmanned aerial vehicle can obtain electric energy from the aerial charging aircraft carrier, and therefore the cruising ability of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular, to a high-altitude non-contact energy supply system and method for unmanned aerial vehicles. Background technique [0002] At present, UAVs powered by electric energy have become aerial platforms for special tasks such as monitoring, telemetry, detection, and elimination of dangerous situations. However, limited by the current battery capacity, the flight time of electric drones is short, which limits the ability and range of missions in complex environments. [0003] After the UAV performs a mission, it generally uses manual recycling to replace the battery, or recharges the battery by wired charging. This method requires manual connection of charging lines, which is inconvenient to operate and high in cost. Some published solutions use wireless charging technology, which eliminates the manual plugging and unplugging operation, and the charging process can be co...

Problems solved by technology

Due to the short distance of wireless charging, it is difficult for UAVs to achieve energy recharge in the air high above the ground. The current solution is to use solar photovoltaic power generation technology to realize the all-weather flight of the aircraft, but it is limited by the large wing area and cost. Due to factors such as high and low-altitude weather conditions, it is difficult to apply to small UAVs
