Safe Driving Vehicle Terminal System Design

With the development of transport industry, people begin to focus on safety problems caused by the driver while enjoying the convenience of cars. According to the traffic accident statistics which show that timeout, speeding, fatigue, and receive calls occupy a large proportion of the traffic safety hazards. So using scientific and technological means to warm driving violations timely, in order to prevent traffic accidents, is one of the key topics of the field of traffic safety. In this background, the paper designs a safe driving monitoring terminal system based on the research of image fatigue recognition.Safe driving monitoring terminal system is based on visual fatigue detection technology, combines with GPS technology and uses GPRS wireless communication network to send monitoring data to the monitoring data center periodically It also has the alarm function of timeout, speeding, fatigue doubt state detection and the function of SOS. In addition the system uses Bluetooth hands-free function to improve the security of answer the phone while driving.Firstly the paper describes the key technology of function implementation in the system. Then after the detailed needs analysis of the system, design the general hardware framework, mainly introducing the design of GPS module, GPRS module, Bluetooth module, micro control unit, the fatigue detection unit and the system power circuit. Next analysis software control flow of the system and write communication program. Finally, test the function of the entire system and solve the problems in the process of debugging. By debugging and melioration, the system is able to complete the design requirements.
