摘　　要：随着汽车购买人数的日益增加,酒驾成为交通事故的主要原因之一。文章以STC89C52为主控芯片,采用MQ-3酒精传感器测定车内酒精浓度,再通过A/D转换为电信号,如果酒精浓度超过预先设定的值,则被智能防酒驾系统自动判断为酒后驾车,这时系统输出不允许汽车启动的指令,并将其发送给关联的亲友,避免酒驾以及作弊行为。仿真测试结果表明,该系统在检测和预防酒驾方面具有较高的灵敏度和准确性,以及较高的实用价值。With the increasing number of people buying cars,drunk driving has become one of the main causes of road accidents.This design USES STC89C52 as the main control chip,adopts mq-3 alcohol sensor to detect the alcohol concentration in the car,and then converts it into an electrical signal through A/D.If the alcohol concentration exceeds the preset value,the system will judge it as drunk driving.At this time,the system outputs instructions and the car is not allowed to start,so as to realize the purpose of preventing drunk driving.Also send messages to related friends and relatives to avoid drunk driving and cheating.The simulation results show that the detection sensitivity and accuracy of the system are high,and it can prevent drunk driving.
