The Design And Implementation Of Vehicle Active Safety And Traffic Information Collection System

The rise of Internet of Vehicles technology has brought new opportunities for the development of intelligent transportation technology, vehicle equipment has almost become a necessity vehicles. Adhering to the "Scientific Guard, Public Safety" concept, How to use technical means to prevent accidents. Take safety measures on the vehicle warning technology, which can effectively reduce traffic accidents. Road traffic is carried out on the basis of urban design and management of urban planning and management, it is the people’s livelihood issues of concern to the people. So city traffic access to information is very important.Paper-based development status car networking and mobile technology, designed a set of vehicle active safety systems for early warning and traffic information collection function. Where the vehicle active safety warning by Zigbee communication technology vehicles to communicate with cars pass each vehicle location information to determine whether the vehicle is in critical condition and alert the driver; Traffic information collection is the use of technology to collect various sections of floating car traffic, traffic information will be uploaded to the control center, the information collected by the control center of the traffic statistics.First, System functional requirements and performance needs to make a brief analysis, select the appropriate software development model that describes the system works and the data flow diagram.Secondly, the key issue for the papers to be studied: GPS positioning system in the security warning, and discusses the major problems positioning errors; In the Zigbee communications technology, demonstrated whether the time required to establish a network to meet demand, the transmission distance meets the needs of early warning function; In the traffic information collection process, given section of road GPS nodes matching models.Then,I member android system with a hardware platform, combined with onboard hardware resources and android system characteristics, transplant developed bootloader U-Boot, and transplanted the Linux kernel and Android.Finally, a detailed description of the construction of the next prototype model system structure, divided each module functions, and interactions between modules, and then focus on data collection, terminal procedures, and data access center three modules for detailed analysis and implementation.Paper design a system that has a vehicle active safety warning and traffic information collection function。Vehicle active safety warning function in the use of car networking technology to communicate warning truck, which can effectively reduce traffic accidents; traffic information collection function uses a floating workshop collect traffic information, traffic information collection make up the existing traditional technologies existing data incomplete, data insufficient, and poor data quality.For the development of intelligent transportation systems played a catalytic role,has important theoretical significance and broad application prospects, there is a significant social and economic benefits.
