Automatic propeller stopping control system and method of unmanned aerial vehicle and unmanned aerial vehicle

Abstract

The invention provides an automatic propeller stopping control system and method for an unmanned aerial vehicle, which are applied to the unmanned aerial vehicle. The control system comprises a sensor device and a flight control device electrically connected with the sensor device. The sensor device is used for detecting at least one of flight parameters and flight attitudes of the unmanned aerial vehicle. And the flight control device is used for analyzing at least one of the flight parameters and the flight attitude detected by the sensor device, and generating a control signal for controlling a power device of the unmanned aerial vehicle to stop rotating when an analysis result of the at least one of the flight parameters and the flight attitude is abnormal. The control system can trigger the unmanned aerial vehicle to stop propellers according to the abnormal flight parameters and / or the abnormal flight attitude of the unmanned aerial vehicle in the flight and recovery process of the unmanned aerial vehicle, and the situation that the unmanned aerial vehicle transversely moves in the falling process and even falls in an accelerated mode after being overturned is avoided.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an automatic propeller stop control system and control method of an unmanned aerial vehicle and an unmanned aerial vehicle. Background technique [0002] Current UAVs include fixed-wing UAVs and rotary-wing UAVs with rotors that can take off and land vertically. For rotor UAVs, the propellers are generally driven by corresponding motors to rotate, thereby generating different magnitudes of pulling force to make the UAV take off, fly or land. [0003] UAVs need to maintain a stable attitude when flying in the air. When the UAV's attitude is out of balance due to collision with obstacles, excessive wind speed or mechanical failure, it will cause the UAV to lose control. At this time, if the UAV is within the visible range, experienced pilots can judge whether the UAV cannot return to a safe flight state by observing the UAV's attitude, flight speed, and flight hei...

However, two-person operation requires additional human assistance and may present coordination issues

It is too difficult and dangerous for a single person to operate. When the drone is too heavy or too large, it cannot be grasped with one hand
