Method and system for automatic wireless charging of unmanned aerial vehicle

Abstract

The present invention relates to the unmanned aerial vehicle wireless charging technology field, and discloses a method and system for automatic wireless charging of an unmanned aerial vehicle. In the unmanned aerial vehicle automatic wireless charging method, a four-step localization method is employed and comprises: firstly, performing coarse positioning through a satellite, and obtaining a coarse positioning area; secondly, performing fine positioning at the coarse positioning area through adoption of infrared ray intensity, and obtaining a fine positioning area; thirdly, performing finer positioning at the fine positioning area through adoption of laser enclosed to a certain area, and obtaining a finer positioning area; and fourth, detecting point laser at the finer positioning area, obtaining final positioning, and performing automatic wireless charging after the final positioning. The positioning precision is very high, the algorithm is simple, the calculation amount is little, the positioning speed is fast, the wireless charging efficiency and the unmanned aerial vehicle cruising ability are greatly improved, the requirement for the hardware performance is low, and the cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless charging for drones, and in particular relates to an automatic wireless charging method and system for drones. Background technique [0002] UAV is a powered, controllable, capable of carrying a variety of mission equipment, performing a variety of tasks and reusable aircraft. Unmanned aircraft that can be controlled by wireless remote control equipment and its own control devices, such as unmanned helicopters, unmanned fixed-wing aircraft, unmanned paragliders, etc. Widely used in aerial photography, monitoring, investigation and other fields. [0003] However, due to the limitation of battery technology and charging technology, the continuous working time of drones is extremely short, which greatly restricts its application. After flying for a period of time, the UAV must return for power replenishment. However, most of the existing UAV power replenishment is achieved by changing the battery ...

AI Technical Summary

Problems solved by technology

Most of the existing fully autonomously controlled UAVs use GPS for positioning, such as the open patent: CN205958757U, but the positioning accuracy of GPS is not high enough, and the error can reach several meters. In order to improve the positioning accuracy of UAVs, some Use infrared for auxiliary positioning, such as the public patent: CN106371463A, and some use icons for auxiliary positioning. Although the positioning accuracy is improved to a certain extent, the accuracy is still not high enough to make the wireless charging transmitting module and the wireless charging receiving module accurately aligned. , thereby reducing the efficiency of wireless charging. In addition, in order to improve the positioning accuracy of existing drones, the algorithm is complex and the calculation is large
