摘要
针对越来越频繁的酒后驾驶和因其引起的交通事故问题,设计一款能自动检测酒后驾驶并自动切断电源的系统装置。采用mq-3酒精传感器模块采集酒精浓度信号,该传感器输出0~5 V的电压信号,然后通过ADC0832模数转换器将采集到的模拟信号转换成数字信号,经过STC89C52单片机控制并将检测到的酒精浓度值显示在LCD12864上。当检测到的酒精浓度值超过酒驾规定值时,蜂鸣器会发出声光报警提醒驾驶员安全驾驶。当酒精浓度值超过交通法安全驾驶规定值时,驱动继电器切断汽车引擎电源,实现了智能闭锁的功能。通过对系统进行软硬件设计调试,证明了该酒后驾驶智能闭锁系统检测速度快、准确率高。
This article focuses on more and more frequent drunk driving and traffic accidents caused by it,and designs a system device that can automatically detect drunk driving and automatically cut off the power.The mq-3 alcohol sensor module is used to collect the alcohol concentration signal.The sensor outputs 0~5 V voltage signal,and then the acquired analog signal is converted into a digital signal by the ADC0832 analog-to-digital converter,which is controlled by STC89C52 microcontroller and displayed the detected alcohol concentration value on LCD12864.When the detected alcohol concentration value exceeds the drunk driving limit value,the buzzer will sound and light alarm to remind the driver to drive safely.When the alcohol concentration value exceeds the safe driving regulations of the traffic law,the drive relay cuts off the power of the automobile engine to realize the function of intelligent locking.Through the software and hardware design and debugging of the system,it is proved that the drunk driving intelligent locking system has high detection speed and high accuracy.
