Folding propeller control method, device and equipment

Abstract

The invention provides a folding propeller control method and device and folding propeller control equipment. The method comprises the steps that before a drone takes off, when at least two blades ofa folding propeller is folded, a controller sends a driving signal for controlling the folding propeller to unfold to a motor, wherein the driving signal is used for driving the motor to speed up forrunning; when it is monitored that the rotating speed of the motor reaches maximum propeller spinning speed and the folding propeller is in a folded working state, the motor is driven to slow down forrunning; the maximum propeller spinning speed is smaller than a take-off rotating speed of the drone; the processes of driving the motor to speed up for running and driving the motor to slow down forrunning are executed repeatedly until it is monitored that at least two blades of the folding propeller are in a completely-unfolded working state. According to the folding propeller control method,device and equipment, by controlling the motor before the drone takes off, the folding propeller is automatically unfolded before take-off, and the rollover risk caused by direct take-off of the droneunder the situation that the propeller is folded is avoided.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle control, in particular to a method, device and equipment for controlling a folding propeller. Background technique [0002] With the improvement of the level of science and technology and people's living standards, people have higher and higher requirements for the performance of UAVs in all aspects. The miniaturization of UAVs is a major trend in the development of civilian UAVs. To adapt to the development of miniaturization of UAVs, folding propellers for UAVs have emerged as the times require. For example, folding UAVs are generally equipped with folding propellers. [0003] Folding propellers generally include blades and paddle clips. The paddle clips are used to fix the blades. The blades can be folded and opened at will to save the space occupied by the drone. However, in the existing folding propellers, due to problems such as production techniques, the damping between the...

Problems solved by technology

After the folding propeller is installed on the motor of the UAV, the user often needs to manually open the folded blades to proceed with the take-off process. Otherwise, if the user forgets to open the propeller or the propeller is not fully opened, If you directly control the drone to fly, it is easy to roll over the drone during the flight

This phenomenon not only increases the risk of drone damage due to rollover, but also affects the user's operating experience
