论道路交通预警与防撞系统研究

杜垒 李晓明 李科峰

摘 要：我国交通安全一直存在一定的矛盾，由于我国近年来经济发展迅速，而我国的道路交通设施相对滞后，所以各种道路交通事故便一直居高不下。故使得我国道路安全形势日益严重。如何减少交通事故已经成为了公众十分关注的一个问题.充分发挥科学技术在预防交通事故中的作用和威力，是我们大学生发挥自我才能来解决实际问题，是目前切实可行的办法，也是我国解决交通问题指明了方向。通过我们平时的学习设计出一款新型的交通防撞系统来解决日益严重的交通问题。在二次雷达用应答机确定飞机的编号、航向和高度的原理上，把询问装置装在飞机上，使飞机之间可以显示相互之间的距离间隔，从而使驾驶员知道在一定范围内飞行的航空器之间的相互间隔及时采取措施，避免碰撞。和二次雷达一样，TCAS系统需要飞机上都装有应答机才有作用。

Abstract： China's traffic safety has been a certain contradiction， because of the rapid economic development in recent years， and China's road traffic facilities are relatively lagging behind， so all kinds of road traffic accidents have been high.Therefore， the road safety situation in China is increasingly serious.How to reduce traffic accidents has become a matter of great concern to the public. To give full play to the role and power of science and technology in preventing traffic accidents is the practical solution for college students to solve practical problems by exerting their talents， which is the current practical way and the direction for China to solve traffic problems.Through our usual study to design a new traffic collision prevention system to solve the increasingly serious traffic problems.On the principle that the transponder is used to determine the number， direction and altitude of the aircraft in the secondary radar， the interrogation device is installed on the aircraft so that the distance interval between the aircraft can be displayed， so that the pilot knows the distance between the aircraft flying in a certain range and takes measures in time to avoid collision.Like secondary radars， the TCAS system works only if the aircraft is equipped with transponders.

Key words： traffic;Radar;Collision avoidance

0引言

隨着我国经济的急速发展，我国已经开始了面向全面小康社会的步伐，汽车，逐渐从奢侈的消费品演化成较平凡的货品，慢慢面向普通人民家。到了今天，买一辆车已经变成不是百万富翁的象征，数以亿计的普通家庭开始拥有汽车。但是，正当汽车的使用是我们出行游玩提供了便利的时侯，高速公路上的长时间驾驶带来的疲惫，和驾驶时打电话、看视频会议、文字聊天等一连串不好的驾驶方式而引致的此起彼伏的危险却也正慢慢地，一步一步地朝我们靠近，那便是人人都不想发生而随时可能出现的灾难。……
