基于单片机的汽车酒驾检测系统研究

Automobile Drunk Driving Detection System Based on Single Chip Microcomputer

酒驾早已成为交通事故的高发原因,为了能更好的降低社会酒驾事故的发生,通过以单片机为主要控制中心搭建汽车酒驾检测系统。通过获取车主授予权限,以座椅压力传感器、安全带位置传感器以及酒精传感器为触发条件触发酒驾检测系统的运行,通过合泰单片机控制蜂鸣器模块进行警示、控制汽车启动系统进行启动断路以及控制GSM通讯模块向驾驶员预留家属号码进行短信发送以及电话播送,通过预设音频对家属及时提醒,以达到从源头上制止驾驶员酒驾的目的。该酒驾检测系统以单片机为独立控制系统进行设计,具有成本低、结构简单、响应快、故障率低等特点适合广泛推广以降低群众人民的酒驾风险。

Drunk driving has already become a high incidence cause of traffic accidents.In order to better reduce the occurrence of social drunk driving accidents,an automobile drunk driving detection system is built with a single chip microcomputer as the main control center.By obtaining the authority granted by the owner,the operation of the alcohol driving detection system is triggered by taking the seat pressure sensor,seat belt position sensor and alcohol sensor as trigger conditions,the buzzer module is controlled by the Hetai single chip microcomputer to warn,the vehicle starting system is controlled to open circuit,and the GSM communication module is controlled to reserve the family number for the driver for SMS sending and telephone broadcasting,and the family members are timely reminded by preset audio,So as to prevent drivers from driving under the influence of alcohol from the source.The alcohol driving detection system is designed with single chip microcomputer as an independent control system.It has the characteristics of low cost,simple structure,fast response and low failure rate.It is suitable for wide promotion to reduce the risk of alcohol driving among the people.
