摘要
酒后驾车造成交通事故不计其数,带来很大危害。各国都在采取各种方法来解决这个问题,但最终没有找到一个很好的解决方法。
酒后驾车控制器就是因此而设计的。在这之前,同类产品国内外已有,但都因为成本、可靠性、方便性等原因没有得到推广。
本设计就是在前人基础上,使其有效、可靠的控制酒后驾车,并将完善其他功能。最终目的是使它能够得到广泛应用,最大限度的限制和杜绝酒后驾车现象。
设计采用半导体酒精探头,其特点是灵敏度高、稳定、可靠;控制器采用89C2051单片机,其具有体积小、功耗低和带有电位比较器;设计上采用发射和接收分离的无线传输技术,使其设备体积小、使用方便、易操作、易安装等特点。此外发射端发送信息码,接收端检验接收码正确性,从而增加了电子锁的功能;整体来说,该设计有成本低、结构简单、可靠性强、易于使用的特点,将会成为汽车上不可或缺的安全工具。

Abstract
Causing the traffic accident to be countless by car after drinking, bring and endanger greatly. Various countries are taking various kinds of methods to solve this problem. But has not found a very good solution finally.
The controller is what is designed because of this to drive after drinking. Before this, there are the like products have both at home and abroad, but because of the cost, dependability , the reason of helping etc. is not popularized .
It is to make its effective , reliable control drive after drinking on the basis of forefathers to originally design, and will perfect other functions. The final purpose is to make it used widely, maximum restriction and phenomenon of stopping to drive after drinking.
Designing and adopting the semiconductor alcohol sensor, its characteristic is that sensitivity is high , and steady , reliable ; The controller adopts 89C2051 one-puter, it has small , low power dissipation and having electric parators; Adopt launching and receive the wireless transmission technology separated on the design , make its equipment small , easy to use , easy to install, in addition launch the end to send the information yard , receive the end to examine and receive one yard of exactness, thus the function increasing electron locking; Come wholly to say , this design is with low costs , of simple structure, will e a tool which indispensable on the automobile with.
