A system and method for self-inspection remote control detachment of a large unmanned aerial vehicle

Abstract

The invention discloses a disengagement device for a large unmanned aerial vehicle. The disengagement device comprises a body, a push rod motor, a feedback module and a receiving module. The body comprises a lock arranged at one end and a connecting mechanism located at the other end, and the lock and the connecting mechanism are used for being connected with the unmanned aerial vehicle and a launching cradle respectively. The push rod motor is contained in a cavity of the body and provided with a telescopic push rod and can stretch into the lock of the body or retract from the lock. The feedback module is arranged in the cavity of the body and used for detecting the locked or disengaged connecting state of the push rod motor and the lock in real time and feeding the connecting state to an external control platform. The receiving module is arranged in the cavity of the body, electrically connected with the push rod motor and used for receiving an external control signal and sending the external control signal to the push rod motor to drive the push rod motor to stretch into the lock or retract from the lock so as to control the connecting state of the push rod motor and the lock. The invention further discloses a corresponding disengagement take-off method. By means of the disengagement device and the disengagement take-off method, stable and reliable connection in the unmanned aerial vehicle loading and transporting and lunching processes can be effectively guaranteed; besides, effective and reliable disengagement in lunching can be guaranteed.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a detachment system and method for large unmanned aerial vehicles. Background technique [0002] At present, the launch method of large UAVs is mainly vehicle-mounted launch. The vehicle-mounted launch method is mainly to use a tractor to drive the UAV to the take-off condition and then release it from the system to achieve successful launch. Due to the large size and mass of large UAVs, the UAV needs to be connected, fixed, and launched during the vehicle-mounted launch process. Therefore, a safe, reliable, and easy-to-operate detachment system is a prerequisite for successful UAV launch. [0003] For example, the patent document CN104354873A discloses a disengagement system for a large unmanned aerial vehicle, which includes a lock body, a lock pin that is arranged on the lock body and can be pulled out, and a retractable electric push rod for pulling the lock pin.

Problems solved by technology

[0004] However, the release of the above-mentioned release device requires the operator to control the release device by wire in the loading vehicle. However, the operator cannot accurately judge the take-off conditions of the drone outside the vehicle and the take-off environment around the scene in the loading vehicle, which may easily lead to take-off failure. ; Moreover, in the process of UAV shipment and launch, due to reasons such as vibration and misinstallation, it often leads to the situation of disengagement from the lock, which has an adverse effect on the stable launch of the UAV, and cannot guarantee the stability of the UAV and the launcher.
