基于PROTEUS的防酒驾系统虚拟仿真研究

摘要

为了检测驾驶员呼出气体的酒精浓度,避免酒驾造成交通事故,设计一种以气敏传感器和ATmega16单片机为主的防酒驾系统.通过酒精传感器MQ-3检测车内空气中的酒精含量,把检测的信息送单片机进行处理.若单片机判断酒精没有超标,可以启动汽车;否则会自动切断启动电路,并发出声光报警.完成理论设计后,利用PROTEUS软件对该系统进行虚拟仿真.实验结果表明,安装该系统可以达到预防酒驾的目的.%In order to detect the alcohol concentration of breathing gas ,aviod accidents caused by drunk driving.We design preventing drunk driving system based on ATmega16 and MQ-3.We detect the alcohol concentration inside the car by MQ-3,then sent the information to ATmega16.If the MCU judge alcohol concentrationre is not exceeded.We can start the car;otherwise, we can not. at the same time there is sound and light alarm.After finishing the theoretical design ,we simulate it based on PROTEUS. The experiment results show that installing the system can achieve the purpose of the prevention of drunk driving.
