Design And Implementation Of An Intelligent Vehicle Terminal System Based On Vehicle Network

Recently,with the rise of the Internet industry and the rapid development of mobile communication technology,people are no longer confined to traditional traffic control,the concept of intelligent transportation system gradually approaches people's attention.According to the future development trend of ITS,this dissertation combines Beidou navigation technology,wireless communication technology,sensor acquisition technology and embedded system development technology and design a new vehicle network intelligent vehicle terminal system,which has the functions of vehicle positioning information,vehicle driving data,sensor information display,driving behavior analysis,etc.The main work and research results of this thesis are listed as follows:Firstly,in the process of development and design of the vehicle intelligent terminal system,the fourth generation of wireless communication technology,Beidou positioning technology,embedded system development technology,Linux programming technology and multi-sensor fusion technology are introduced.On the basis of research status and development trend of ITS,we design the overall framework and structure of the system and detailed analyze and discuss the functions of each part of the system.Secondly,the key technologies of the intelligent vehicle terminal system are introduced,which include the fourth generation mobile communication technology,Beidou satellite positioning technology,vehicle information collecting technology.The application of each technology in the intelligent vehicle terminal are analyzed and discussed in detailed.Thirdly,on the basis of the demand analysis of the vehicle intelligent terminal system,these focuses on the design of the hardware circuit of the system.The system qucuires various vehicle sensor parameters through CAN bus and uploads the vehicle driving data to the terniman system for processing and storage through CAN bus communication.The system utilizes the Beidou positioning module for vehicle positioning and navigation.The 4G module is employed to upload the positioning information and vehicle driving state information and other parameters to the monitoring center.Fourthly,the system uses the embedded Linux operating system to develop the functions of the intelligent vehicle terminal,including the realizationof the positioning function,the realization of the vehicle identity authentication function and the realization of the vehicle information collection function.On this basis,the functions of the vehicle intelligent terminal system were tested.Moreover,the event reporting records and the vehicle driving data information timing report records were displayed.Finally,the full thesis is summarized.
