WIND SPEED DETECTION METHOD AND SYSTEM FOR UNMANNED AERIAL VEHICLE, AND UNMANNED AERIAL VEHICLE

摘要

Disclosed are a wind speed detection method and system for an unmanned aerial vehicle, and an unmanned aerial vehicle. The unmanned aerial vehicle comprises a propeller (20) and a motor (30) for driving the propeller to rotate. The method comprises: S101, obtaining the rotation speed of the motor (30) of the unmanned aerial vehicle, wherein the rotation speed is the rotation speed of the motor (30) when the propeller (20) rotates windward; and S102, determining the wind speed of the unmanned aerial vehicle in the current environment based on the rotation speed of the motor (30). In this way, the unmanned aerial vehicle is used to determine the wind speed in the current environment, and the security risk caused by rashly launching the unmanned aerial vehicle when the wind speed is too fast is avoided, and the flight safety of the unmanned aerial vehicle is guaranteed.
