摘要
为了能有效减少因为酒后驾车而造成交通事故的现象,使用一种ARM的Cortex-M3微处理器,采用半导体酒精传感器进行数据采集,在车内3个不同的位置采集酒精浓度信号,通过无线的方式发送给接收机,接收机根据车的行驶状态实时处理3个信号,进行数据融合然后做出相应的判断,发送无线控制信号给汽车制动系统,并且提供声音报警的功能。该设计创新性的利用多个传感器探测,并且无线传输信号,非常有利于在汽车上的装载,能够有效杜绝酒驾的行为。
In order to reduce the phenomenon of traffic accidents caused by drunk driving effectively, a system of the measuring alcohol concentration on the car was designed with Cortex-M3 microcontroller .The system used semiconductor alcohol sensor to collect data and acquired alcohol concentration signal in three different locations on the car and sent data to the receiver wirelessly.The receiver dealed with three signals based on the car＇s driving state,then judged to send control signal to the vehicle braking system wirelessly.It provided audible alarm function. The design used multiple sensors detection, transmitted signals wirelessly, and was very conducive to load in the car.
