Design And Implementation Of Vehicle Anti Drunk Driving System Based On Internet Of Things Technology

With the rapid development of automobile industry,vehicle ownership is increasing.Vehicle driving safety has become the focus of attention in today’s society.However,drunk driving is one of the most important factors that cause road traffic accidents.Therefore,in order to reduce the loss and personal safety accidents caused by drunk driving,the intelligent monitoring system for preventing drunk driving has become the focus of all walks of life.In this regard,based on the Internet of things technology,in-depth analysis of vehicle anti-drunk driving system is carried out.First of all,on the basis of studying domestic and foreign literature,from the perspective of active safety and intelligent monitoring,an intelligent vehicle driving intelligent prevention system based on the Internet of things is proposed in view of the road wine driving behavior in China.Then,the theoretical research on vehicle driving prevention system of Internet of things is carried out.The mechanism and method of vehicle alcohol concentration detection are analyzed.Meanwhile,the technical means to prevent drunk driving is put forward.Secondly,the flow chart of intelligent monitoring system for preventing drunk driving is designed by using GSM communication technology and transmission self-locking technology.In addition,the alcohol sensor circuit,LED alarm circuit and LCD display circuit are designed combined with the flow chart of intelligent monitoring system for drunk driving.Thirdly,the hardware design of the prevention of drunk driving system is carried out.At the same time,Keil4 programming software is used to complete the whole system programming.The system embodies the functions of alcohol judgment,information collection,system alarm,display,self locking and so on,which effectively avoids the driver’s drunk driving behavior.Finally,the hardware circuit and the software program are combined to carry out experiments and debugging.When the alcohol concentration in the cab is more than 45ppm,the LED red indicator light is bright,the automatic transmission is locked,and the binding number is communicated.After several experiments,the feasibility of preventing the driving function of the system is verified.Experiments show that the intelligent monitoring system based on Internet of things to prevent drunk driving has an effective preventive effect on drunk driving.It not only realized the rapid and accurate detection of the alcohol concentration of the driver,but also realized the information of the wine driving by the Internet,so as to avoid the occurrence of the alcohol driving behavior.This provides an active protection for traffic safety,and has certain practical value for preventing drunk driving.
