Design And Application Of Multi-function Information Publishing System Based On Vehicle Networking Technology

Now people are more and more concerned about the level and quality of transportation,and their demand has become a topic of widespread concern in today's society.In the urban traffic and urban air pollution is serious in the context,establish a multifunctional information service platform based on to the vehicle is the traditional single car system just integrating the network and application only,making the car networking system and society as a whole fused into a unified body,so as to make the car networking system to maximum extent reflects the social value is particularly important.Wireless sensor network technology and embedded computer technology has been continuously developing,a vehicle networking technology research and application by the extensive concern of the domestic and foreign research institutions,the project developed a strong technical foundationIn this paper,the design of a car based on the network technology of the multifunctional,information service system,this system mainly includes three subsystems,respectively,for the highway vehicle warning subsystem,car video surveillance system and atmospheric pollution monitoring subsystem.And there are introduced from the perspective of the system's functional demand,the overall structure,hardware design,network topology and communication protocol,host monitoring and data mining analysis.The vehicle early warning subsystem is designed to obtain information in the accident through DB technology and short-range RF technology and provide early warning of nearby vehicles,so as to avoid traffic accidents.The wireless communication and routing protocol are analyzed,and the scheme of CSMA/CA is introduced.In the vehicle video surveillance subsystem,a video information segmentation method is proposed,and its effectiveness is explained in principle.For the air environment monitoring system,through the design of user client,the experimental data is analyzed by using the inforstack platform,which provides reliable data support for the development of air pollution control measures.
