摘要
对导致交通事故的原因进行了研究,酒驾已成为交通事故高发的主要原因之一.酒精浓度的检测是评定酒驾的重要环节,为提醒驾驶员避免酒驾,设计了一个基于单片机的车内酒精自检系统,通过MQ-3酒精传感器对车内的酒精浓度进行实时监测,将采集的模拟信号经过A/D转换传送到STC89C52RC单片机,处理后的数据通过LCD显示屏进行显示.若检测的气体中酒精浓度超过预定的阈值,系统会发出声光报警,警报可以引起注意.与此同时,继电器控制的电路也会使汽车进行制动,使汽车无法启动.该系统体积小、携带方便,并具有一定的预防酒驾的功能,保证交通安全.
Abstract
The cause of traffic accidents has been studied,and drunk driving has become one of the main reasons for the high incidence of traffic accidents.The detection of alcohol concentration is an important part of assessing drunk driving.In order to remind drivers to avoid drunk driving,a alcohol self-checking system in car based on Single-Chip Microcomputer is designed.The alcohol concentration in the car is monitored in real time through the MQ-3 alcohol sensor,and the collected analog signal is converted to STC89C52RC Single-Chip Microcomputer by A/D conversion.The processed data are displayed through the LCD display.If the alcohol concentration in the gas exceeds the threshold,the system will send out a sound and light alarm which can attract attention,and at the same time,the circuit controled by relay will brake the car so that the car cannot be started.The system is small in size,easy to carry,and has a certain function of preventing drunk driving to ensure traffic safety.
