Abstract: This design describes how to reduce the increasing death rate of traffic accidents in my country. In response to this problem, an automatic alarm for car accidents based on Beidou positioning is proposed. It analyzes the application of Beidou positioning in the automatic alarm of car accidents, uses the pressure sensor, Beidou positioning module and gyroscope: MPU-6050 acceleration measurement module to judge whether there is a car accident, uses the SIM800C wireless communication module for the alarm function, and briefly analyzes the car accident Judgment algorithm implementation principle and calculation process. Finally, this system can bring hope of life to people in car accidents and give travel a guarantee.
Key words: embedded system; beidou positioning system; car accident alarm
