摘要
随着我国经济迅速且平稳的发展,私家车和商务车成了人们必不可少的代
步工具,越来越多的人和家庭拥有了属于自己的汽车,但是,道路交通事故的
发生也越来越频繁,数据显示,道路交通事故成了人类死亡的第九类原因,预
计在 2020 年,交通事故死亡率将翻一番,成为继癌症,抑郁症之后的第三大死
亡原因,虽然国家采取了一系列的政策来预防交通事故的发生,但交通事故还
是屡见不鲜。而 49%-59%的交通事故与酒后驾车或者醉酒驾车有关,酒后驾车
已经成为目前车祸死亡的主要原因之一。针对酒后驾车这种害人害己的行为,
司机酒后发动机不能启动系统的设计是非常有必要的。若司机在酒后开车,该
系统的设计基于 AT89C51 单片机的控制,利用酒精探测器对司机呼出的气体进
行检测,为了降低乘车人员饮酒对酒精探测器的影响,应进行多次实验并取平
均值。酒精挥发到空气中会迅速扩散,所以酒精探测器的显示数值会比实际值
偏小,应该在酒精探测器的显示数值上做放大改动。当酒精浓度超标时,该系
统能控制继电器强制切断发动机的电源,使发动机因为断电而不能启动,从而
间接的达到保护司机和乘客安全的目的。

Abstract
With the rapid development of our economy, cars have become
indispensable means of transport, more and more families have cars, at
the same time, traffic accidents have become increasingly frequent, data
show that the traffic of the ninth types of causes of death in humans, is
expected in 2020, the traffic accident death rate will be doubled, become
the causes of cancer, depression after third deaths, although the state
has adopted a series of policies to prevent the occurrence of traffic
accidents, traffic accidents but It is often seen. And 49% -59% of the
traffic accident and drunk driving or drunk driving, drunk driving has
become one of the main reasons for the death of the current car accident.
In view of the harm of drunk driving behavior, drunk engine can not start
the system design is very necessary. If the driver was drunk driving, the
system can measure the alcohol concentration, alcohol concentration
display through the digital tube, the force that the engine can not
start, and audible alarm, in order to reduce the probability of drunk
driving accident risk.The design of the control system based on AT89C51
MCU, detected by gas exhaled alcohol detector to the driver, passengers
in order to reduce the effects of alcohol on the alcohol detector, should
be carried out many experiments and averaged. Alcohol evaporates into the
air and spreads quickly, so the display value of the alcohol detector is
smaller than the actual value, which should be changed on the display
value of the alcohol detector. When the alcohol concentration exceeds the
standard, the system can cut off the power supply, so that the engine can
not start, so as to achieve the purpose of protecting the safety of
drivers and passengers.
