摘　　要：文章介绍了一款汽车倒车测距警示系统,它是基于PIC16F877单片机控制的。采用超声波测距,用PIC16F877单片机算出障碍物体和车子后面的距离,对看不到的区域进行红外感应监测。而且会利用LCD屏反应出障碍物体到车子后面的距离,并有警报声响起。从而让驾驶员快速了解车尾的状况,并采取对应的措施,来提高倒车的安全性。This paper introduces a car reverse ranging warning system, which is based on PIC16F877 single chip microcomputer control. Ultrasonic ranging is used to calculate the distance between the obstacle object and the back of the car by PIC16F877 single chip microcomputer, and the infrared induction monitoring is carried out in the area that cannot be seen. It also uses the LCD screen to reflect the distance from the obstacle to the back of the car, and an alarm goes off, in order to let the driver quickly understand the situation of the rear of the car, and take corresponding measures to improve the safety of reversing.
