Design And Implementation Of Vehicle Information Collection And Intelligent Analysis System

In recent years,people’s living conditions have been significantly improved,the number of cars has continued to increase,road traffic congestion has gradually emerged,the problem of traffic congestion has become more prominent,and intelligent transportation systems have received widespread attention.In the context of macro policies such as intelligent transportation and Internet of Vehicles,the level of informatization of traffic management has been greatly improved,and the use of information technology to accelerate the development of the field of intelligent transportation has become one of the most popular research topics in Internet of Vehicles.The emergence of the Internet of Vehicles technology has led the intelligent transportation technology into a new development period,and has made on-board equipment a must-have for vehicles in daily travel.To implement the concept of "public safety and technological innovation",how to use advanced technology to avoid traffic accidents has become the focus of more and more people.Urban managers and designers rationally plan and manage urban development on the basis of urban traffic flow,which is also a livelihood issue closely related to every citizen.Fast and effective automobile information collection and intelligent analysis system is an important development direction of current automobile management,which plays an important role in alleviating road traffic pressure.First of all,this article summarizes domestic and foreign research and understands that the current traffic congestion problem is solved mainly by building vehicle information collection and analysis systems.Among them,the use of AMR sensors to obtain vehicle information has better collection accuracy,reliability and application value.Therefore,this research proposes a scheme of vehicle information collection and intelligent analysis system.Secondly,it puts forward the demand analysis of vehicle information collection and intelligent analysis system,and discusses the framework of the whole system.The system mainly includes three parts: data receiving system,geomagnetic acquisition system and human-computer interaction system.Thirdly,design and implement the hardware and embedded software of the vehicle information collection and intelligent analysis system,design the hardware framework,select the components according to the system requirements,and then design the hardware function module circuit,specifically the power supply circuit design,AMR sensor circuit design,analog-to-digital conversion circuit design,signal processing circuit design,data storage circuit design and microcontroller circuit design,etc.,and draw PCB circuit boards.Finally,the software functions are designed.The specific software functions include basic information management,front-end equipment management,chart visualization management,traffic intelligence analysis management,and system management.The software functions and interface development are completed according to the design flow chart.After the system development is completed,this article builds a simulation model to test the vehicle information collection and intelligent analysis system,including hardware circuit testing,communication testing and road field testing.The test results show that the system has a good detection effect on road vehicles and can meet Expected design requirements.
