摘要随着交通行业技术的发展，以及汽车保有量的增加，汽车给人类带来舒适和便捷的同时，也给人类带来了交通事故频发等交通安全隐患，如酒后驾驶、无照驾驶、违规驾驶等，严重威胁着人类生命和财产安全。特别是由酒后驾车导致的交通事故发生率比较高。因此，从主动安全角度出发，禁止酒后驾驶人员启动汽车引擎，成为在车辆发生事故之前排除隐患的重要研究本设计。 本设计在研究国内外防止酒后驾驶技术的基础上，针对酒后驾车导致交通事故频发的事实，设计一种基于单片机的智能防酒后驾驶控制系统。系统先检测司机呼出气体酒精浓度，显示检测结果，并据此执行相应的控制。本次设计主要完成以下几个方面的工作： （1）根据该系统的实际目的和系统装置所使用的特定环境，选择酒精传感器作为检测驾驶员呼出气体酒精含量的工具；采用合适的单片机、显示模块、报警模块、继电器驱动模块设计硬件系统； （2）在 Keil uvision4 基础上编写完成系统的软件设计，并进行编译调试；（3）在 proteus 环境下对系统进行仿真（4）整合调试软硬件，并调试检验。 关键词：汽车；酒后驾驶；智能闭锁；单片机 AbstractWith the development of transportation industry technology, as well as the increase of car ownership, cars bring people comfortable and convenient at the same time, also has brought human frequent traffic accidents, such as traffic safety hidden trouble, such as drunk driving and driving without a license, driving violations, serious threat to human life and property safety.Especially the traffic accidents caused by drunken driving is quite high.Therefore, from the perspective of active safety, against drunk drivers to start the car engine, be ruled out before vehicle accident hidden trouble of important research in this design.This design on the basis of the research at home and abroad to prevent drunk driving technology, aiming at the fact that drunk driving cause traffic accident frequency, design a kind of intelligent against drunk driving control system based on single chip microcomputer.System to detect ...
