Research And Implementation Of Internet Of Vehicles Safety Monitoring System Based On WebGIS

As an important part of urban information construction,the vehicle network is extensive in the management of the Internet of Things,so it is an inevitable trend to develop in the direction of precision.In this paper,the Internet of Things and Web GIS technology are introduced into the vehicle network information management.The vehicle management system based on the Internet of Things and spatial geographic information technology is studied.A feasible and effective management scheme is proposed,and an efficient and stable vehicle information precise management system is realized.The full text is mainly divided into the following parts,the specific content is as follows:1.On the basis of collecting the basic information of vehicle users,according to the basic requirements of users and collecting vehicle data,the functional requirements are established,and the establishment of database is summarized and improved.2.Based on the basic requirement of monitoring real-time location information of vehicles,technology selection is carried out,including data storage technology selection,data stream processing technology selection,and spatial location calculation framework selection.3.On the basis of the former two works,the B/S system based on Web Socket and Spring MVC open source system is designed and developed to realize real-time pushing and real-time displaying of vehicle data.4.Based on the Open Source Geographic Information System:Post GIS,through the application of spatial database spatial geometric relationship calculation function,combined with electronic maps provided by the Bureau of Surveying and Mapping and user-defined geographic data,vehicle geographic information analysis is realized;vehicle interval speed is calculated by latitude and longitude uploaded from the vehicle terminal,and vehicle speeding alarm is carried out in key sections;user-defined geography is adopted.Data to realize the alarm in and out of a specific area;combined with spatial database and Dijkstra algorithm to achieve the optimal solution of path planning.5.After completing the functions above,the program is continuously simulated and tested.After 15 days of simultaneous,simulate about 60,000 vehicles on line,the system maintains normal operation.The test results meet the performance requirements.Finally,the program deployment in distributed.Through the above research,the following conclusions can be drawn: 1.Introducing the Internet of Things and Web GIS technology into the vehicle information management system,the vehicle information management mode becomes more convenient,real-time,accurate and efficient;2.In the specific design practice,the vehicle network information refinement management system has strong feasibility and scientific nature,and provides for the relevant regulatory departments of vehicle operation enterprises.The data analysis has played a positive role and support for driving safety or operation cost control.Thirdly,the system has fully practiced the concept of "smart city" and has played a positive role in the further development of transportation in China.
