Quick recovery system applied to fixed-wing unmanned aerial vehicle and recovery control method thereof

Abstract

The invention discloses a quick recovery system applied to a fixed-wing unmanned aerial vehicle and a recovery control method thereof. A three-direction displacement device, a motor driver, a recoverydocking device, a pressure sensor, a locking device, a locking device driving circuit, a camera, an unmanned aerial vehicle docking device, an identifier, an analog-to-digital conversion circuit, a processing unit and a power supply are adopted; the processing unit adjusts the displacement device through an image of the camera, so that the unmanned aerial vehicle docking device is aligned with the recovery docking device; pressure signals are obtained through the pressure sensor to judge that the docking is completed, and the processing unit controls the locking device to lock the unmanned aerial vehicle docking device with the recovery docking device. Azimuth perception and measurement and calculation of the unmanned aerial vehicle in landing are achieved, then the position of the docking device is adjusted for alignment, and accurate docking and recovery are achieved; the unmanned aerial vehicle quick recovery system is small in size, capable of automatically recovering unmanned aerial vehicles, higher in recovering speed and small in damage to the structure of the unmanned aerial vehicles, and batch recovery of unmanned aerial vehicle clusters can be achieved through simultaneous works of multiple systems.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a fast recovery system applied to fixed-wing unmanned aerial vehicles and a recovery control method thereof. Background technique [0002] The landing of fixed-wing UAVs requires a long enough runway as a landing condition, which is one of the main factors limiting the application environment of UAVs. With the rapid development of drone technology, people have higher requirements for the rapid launch and recovery of drones. Although the short-range launch technology of drones has achieved rapid development due to relatively low technical difficulty, unmanned However, there are many technical problems that are difficult to solve in the machine recycling technology. Fixed-wing drones stay in the air for a long time and are fast, but when they land, fixed-wing drones need a long runway and take up a long time. In the shipboard environment, the length and width of the runway...
