Unmanned aerial vehicle and method for detecting flight state thereof, and wearable device

Abstract

An unmanned aerial vehicle, a method for detecting a flight state thereof, and a wearable device () are disclosed. The method comprises: disposing a propeller operation state collector () for collecting an operation state signal of a propeller () on at least one support arm () of the UAV (S); acquiring the operation state signal of the propeller () collected by the propeller operation state collector () (S); processing the operation state signal to obtain an operation state of the propeller () (S); and determining the flight state of the UAV according to the operation state of the propeller () (S). By disposing the propeller operation state collector () on the support arm () of the UAV to collect the operation state signal of the propeller (), and then calculating the flight state of the UAV according to the operation state signal, better flight control of the UAV can be achieved by making use of the detected flight state of the UAV, and an desired flight trajectory can be obtained, thereby improving the controllability and safety during the flight of the UAV.
