摘要

针对目前大多数经济实用型汽车、货车等车辆没有装备倒车雷达的现状

设计出一种成本低、结构简单、可靠性高的倒车雷达预警系统。硬件设计主要包括超声波测距电路、单片机控制电路、LCD显示电路、报警电路等;软件设计主要包括超声波测距原理介绍和系统软件工作流程等。汽车倒车时

该系统能够检测出汽车后面障碍物的距离

并且在LCD上实时显示汽车与障碍物之间的距离;当障碍物与车之间的距离超出预先设定的报警距离时

该系统会发出声光报警

提高安全性。实验结果表明:该系统在20

00 cm范围内可实现准确测距

最大平均误差不超过3%

能够在预设的报警距离处及时报警

达到预期目的

具有经济实用、操作简单、性能好等优点。

Abstract

Aiming at status that most compact cars and trucks are lack of reversing radar due to cost constraints

design a low-cost simple structure reversing radar warning system with high reliability. Hardware design consists of ultrasonic wave distance measurement circuit

LCD display circuit

alarm circuit. Software design consists of introduction of ultrasonic ranging principle and workflow of software system. In the process of reversing

the system can detect distance between car and obstacle and display distance on LCD in real time. Once the distance exceeds the preset warning threshold

the audible and visual alarm will be triggered to warn the driver. Experimental results show that the proposed system can achieve correct ranging value of the distance and the maximum average error is not exceed 3 %

the system is also characterized by lower energy consumption and well performance.
