摘要
针对酒后驾车导致交通事故频繁发生的现象,设计了一种能够防止酒后驾驶的自动控制系统。该系统由酒精传感器、AD574A转换器、89C51单片机控制器、语音报警、LED显示、继电器以及电机等构成。用DP—51PROC单片机综合仿真实验仪进行了仿真实验,结果表明:当酒精传感器检测出司机体内酒精浓度超标时,该系统能够自动切断汽车启动系统电源,实现其控制功能。
Aimed at the increasing accidents caused by drunk driving, a anti drunk-driving control system is designed. The designed system is constructed with alcohol sensor, the AD574A converter, the 89C51MCU controller, speech warning system, LCD, relay and the motor, etc. The whole system is simulated using the DP-51PROC integrated simulation hoard, and the result indicates when the alcohol testing result exceeds the safe limit, power supply of the starting system will be cut to stop the ear from start-up.
