摘要
设计了一个基于激光测距的汽车防撞警示系统,在雾霾、雨、雪等能见度低的天气下,如果汽车发生故障停在路边,LED三角警示牌能使后方来车远距离清晰辨识。该设计利用激光测距模块测量后方来车与故障车的距离,当距离太近且后方车辆速度太快时LED三角警示牌自动弹起并点亮,对后方来车驾驶员起到＂预警＂的作用。本次设计的LED三角牌警示系统主要包含四个方面,分别是STC89S52处理模块、激光测距模块、按键输入模块和显示模块。此设计系统测试效果良好,能够实现预期功能,有很好的市场应用前景。
A car collision LED them system is designed, with which the car can be clearly identificated at a distance, if the car stops in the driveway in the low visibility weather such as fog, rain, snow. The design measures the distance to the following car and trouble truck with the laser ranging module. The LED caution sign automatically lights, when the distance is too close and the vehicle speed is too fast, which can warn the following cars＇ drivers. The design of Anti-collision Warning System for Automobile Based on laser ranging mainly includes four aspects, which are STC89S52 processing module, the laser ranging module,key input module and display module. This design system test effect is good, which can realize the anticipated function, and have the very good market application prospect.
