预防酒后驾车智能控制系统关键技术研究

Key technologies to prevent driving under the influence of intelligent control systems

为避免由于酒后驾车以至造成交通事故,文章提出了基于单片机控制的预防酒后驾车智能控制系统的设计方案。该智能控制系统采用软硬件相结合,通过酒精传感器检测,获取驾驶员呼气中的酒精含量模拟值,经模数转换后,由单片机进行分析处理,最终控制汽车能否允许启动,从而达到防止酒后驾车的目的。

To avoid because of drunk driving and cause traffic accident,this paper puts forward the prevention based on single chip microcomputer control drunken driving control system of intelligent design.The intelligent control system by combining software,through the alcohol sensor test,get the driver out of alcohol content simulation value,the modulus after conversion,analysis of microcomputer,and finally process control cars could allow start,so as to achieve the purpose of preventing drunken driving.
