Research Status and Development Trend of Drunk Driving Safety Detection for Drivers

With the increase of motor vehicle ownership, drunk driving has become a major threat to road traffic safety. This paper comprehensively studies the current situation and development trend of drunk driving safety detection, emphasizes the serious impact of drunk driving on traffic safety, and deeply discusses the development of drunk driving detection technology. About 100,000 people die in drunk driving accidents in China each year, research shows, underscoring the need for effective prevention measures. In terms of detection technology, this paper describes in detail a variety of traditional and innovative drunk driving detection methods. This includes in-vehicle drunk driving detection based on artificial olfactory system, multi-modal signal deep fusion of the detection method combining infrared thermal image and electronic nose technology, and the use of multi-sensor information fusion in-vehicle drunk driving detection system. In addition, the design and implementation of car anti-drunk driving system based on Internet of Things technology are also discussed. In particular, this paper presents an innovative concept-a driver monitoring device design based on sweat biosensor and reflective photoplethysmography (rPPG) technology. While this technology has yet to be implemented, its potential applications are predicted and discussed in the paper, including non-contact heart rate monitoring and real-time monitoring of alcohol levels. The proposed concept aims to improve the accuracy and real-time detection of drivers' drinking status and reduce the accidents caused by drunk driving. Finally, the paper looks forward to the future development trend of drunk driving safety detection technology, and points out that the application of Internet of Things technology in the field of driver condition monitoring has great development potential. The further development and application of these technologies will make an important contribution to reducing road traffic accident rates and improving public transport safety.
