Research on UAV Safety Early Warning System Based on STM32 Microcontroller
In view of the requirements of the safety early warning system for detecting its own safety status during the cruise operation of modern UAVs,this paper measures the real-time data based on the wind speed detection sensor based on the pitot tube velocity measurement principle,uses STM32 microcontroller to collect the data within a certain range near each rotor,and automatically compares and calculates the data with the theoretical data accord-ing to the dichotomy principle.At the same time,the real-time safety state information is used as the judgment ba-sis for whether to initialize the buzzer drive circuit,so as to realize the alarm prompt to the operator.The results show that the system can not only complete its own safety warning in the course of cruise operation,but also meet the requirements of field use.
