摘　　要：文章设计一种基于STC89C52的倒车防撞系统,以超声波手段计算距离为核心,以蜂鸣器报警为安全提醒,经过HC-SR04模块的实时测距,在实际应用中能够有效测出障碍物离车的距离,在较近的距离还可以警示驾驶员,大大减小倒车碰撞事故的发生,增加倒车的安全性,即简单又实用。This paper designs a reversing collision avoidance system based on STC89C52,uses the ultrasonic method to calculate the distance as the core,the buzzer alarm as the security reminder,and the real-time ranging of the HC-SR04 module can effectively measure the obstacle in the practical application The distance from the car,at the nearest distance can also alert the driver. Greatly reducing the occurrence of reversing collision accident,increase the safety of reversing that is simple and practical.
