Research On Vehicle Drunken Driving Detection Control System Based On The Multi-sensor Information Fusion

Drunk driving is an important factor in road traffic accidents, which seriously affect the safety of public transportation. The government of all over the world try to stop drunk driving through strict law enforcement,but the effect is not good. Drunk driving seriously affects the safety of public transportation. It is a kind of police recourse wastage and risk by using the handheld breath alcohol testing device.The existing car drunk driving detection method is single, the judgment is not accurate,it is difficult to avoid cheating detection. The study of a car drunk driving test and control system can accurately identify the drunk driving, which is of profound significance to ensure road traffic safety and promote the development of automobile electronic technology.In this paper, starting from the characteristics of driving behavior, by studying the measurement and control system based on the information fusion of multi sensor, we can analyze the impact of alcohol on the human body, and analyze the drunk driver's characteristics and the steering and acceleration characteristics. It is low in detection performance and safety and reliability by using the measurement and control system of drunk driving based on single gas sensor. The D-S evidence theory is proposed as the information fusion algorithm of the system software design. The system can judge the situation of drunk driving by multi index fusion. The results of the identification can be found by the voice of the single chip alarm. The detection result is displayed by LED lcd.The control circuit is controlled by the relay. Force to stop by cutting off the ignition device.By the experimental analysis, the fusion discrimination is accurate, and the error of alcohol concentration detection is in 30 ppmm, the system has better stability.
