Abstract: An antenna signal processing circuit of a smart watch, including: a sensor module, a microprocessor, an antenna body and an antenna tuning circuit having a plurality of tuning paths. The antenna tuning circuit is connected between a smart watch signal source and the antenna body, and the microprocessor is respectively connected to the sensor module and the antenna tuning circuit. The sensor module sends a detected proximity sensing signal to the microprocessor. The microprocessor receives the proximity sensing signal, and obtains a controlling signal, to control the antenna tuning circuit to switch the tuning path and perform tuning processing on a signal from the smart watch signal source or the antenna body. A smart watch and an antenna signal processing method thereof are also provided.

Abstract: An unmanned aerial vehicle, a method for detecting a flight state thereof, and a wearable device (500) are disclosed. The method comprises: disposing a propeller operation state collector (302) for collecting an operation state signal of a propeller (301) on at least one support arm (303) of the UAV (S101); acquiring the operation state signal of the propeller (301) collected by the propeller operation state collector (302) (S102); processing the operation state signal to obtain an operation state of the propeller (301) (S103); and determining the flight state of the UAV according to the operation state of the propeller (301) (S104). By disposing the propeller operation state collector (302) on the support arm (303) of the UAV to collect the operation state signal of the propeller (301), 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
