摘　　要：为降低车辆碰撞事故的发生率,增加车辆行驶安全性,系统设计采用STC89C52单片机为核心控制技术,采用超声波传输电路启动传输信号并发射超声波进行测距;通过无线蓝牙模块将超声波传感器对障碍物测出的距离以及设定的安全距离传输到云端,最终实现一个车辆碰撞预警和控制系统。In order to reduce the incidence of vehicle collision accidents and increase vehicle driving safety,the product design in the paper adopts STC89C52 microcontroller as the technical core control,and uses ultrasonic transmission circuit to start the transmission signal and emit ultrasonic for distance measurement.By using a wireless Bluetooth module,the distance measured by ultrasonic sensors towards obstacles and the set safe distance are transmitted to the cloud,ultimately achieving a vehicle collision warning and control system.
