Design And Research Of Cloud Service Platform In Vehicle Condition Monitoring System Based On V2X

China's car ownership has reached 240 million in 2018.Traffic congestion and traffic accidents have brought many inconveniences to people's lives.Travel safety and travel quality have attracted more and more attention.The V2X(Vehicle To Everything)can establish communication between vehicle and Internet,monitor the vehicle by acquiring the running data and system data of the vehicle,and then judge the safety of the vehicle and avoid crowded roads,to ensure the travel safety of people and improve the comfort of travel.Based on the related technologies of V2X,this paper designs and studies the cloud service platform in vehicle condition monitoring system.Based on the WebSocket full-duplex communication protocol,the proactively push function of the cloud service platform is completed.The cloud service platform can update the received vehicle running data and positioning data to the Web page in real time,to realize the function of vehicle monitoring.Design the back-end processing part,front-end user interface and database of the cloud service platform for data receiving and processing,data display and data storage.In addition,the cloud service platform is programmed by the PHP scripting language,HTML + CSS + JavaScript web design language,etc.The functions of back-end processing part such as user authentication and binding,data parsing and saving,vehicle safety analysis,data push,etc.are completed.The interfaces of the front-end user interface such as registration and login interface,data monitoring interface,data playback interface,vehicle status display interface etc.are completed.At the same time,to realize data visualization,using HighCharts and Gaode Map JS API,the running data and positioning data of the vehicle are displayed on the Web page in the form of dashboard,dynamic change map,map,etc.Finally,the accuracy and stability of the cloud service platform is verified by real vehicle test experiments.The results show that the back-end processing part can parse,save,analyze the received data,and push the data to the front-end user interface;the front-end user interface can accurately display the data in the form of tables,graphs,etc.;the cloud service platform has good working stability.
