Winding device between mother-son unmanned aerial vehicles

Abstract

The present invention provides a winding device between mother-son unmanned aerial vehicles. The winding device is mainly formed a winding system, a guidance system and a suspension system. A windingmode and a suspension mode are taken as essential theories of the invention for application. When an unmanned aerial vehicle aircraft carrier colony works, if a son unmanned aerial vehicle needs to add a work range, a motor stably releases a suspension line with the cooperation of torque sensors to provide suitable transmission line length; if the son unmanned aerial vehicle needs to decrease thework range, the winding system takes up the transmission line according to requirements to maintain the work stability of the unmanned aerial vehicle. In the unmanned aerial vehicle colony work process, each torque sensor monitors torque change in real time and performs feedback to a servo motor, and a closed loop is employed to accurately control the winding device to perform the take-up and pay-off of the transmission line and stabilize the operation of the unmanned aerial vehicle colony. The function cooperation of the motor and the torque sensors and the utilization of the suspension unitallow the transmission line of the unmanned aerial vehicle colony to be stable and accurate operate according to preconception so as to improve the efficiency and the safety.

Description

technical field [0001] The invention relates to the field of multi-rotor UAVs, in particular to a wire winding device between a sub-mother UAV. Background technique [0002] UAV is a rapidly developing aircraft. Multi-rotor UAV, as a kind of UAV, is widely used in aerial photography, power inspection, geographic surveying and mapping, pesticide spraying, etc. UAV carrier is a form of UAV cluster, similar to the basic role of sea carrier, the mother machine in the UAV carrier system acts as a relay station of energy, providing sustainable energy for the sub-UAVs in the UAV carrier system Sufficient energy is supplied; the sub-drone is mainly responsible for the execution of various tasks as a mission machine, and is attached to the parent machine platform when there is no task. The spacing-type suspension winding device between the mother and child UAVs in the UAV aircraft carrier proposed in this patent is actually a solution to the problem that the suspension of the power...
