Design And Realize Of A Remote Monitoring System Based On 4G Network For Electric Vehicle

In today's society,in order to protect the environment,China advocates the development of new energy electric vehicles,but the technology of new energy electric vehicles is not perfect,new energy electric vehicles are prone to accidents in driving,it needs to be monitored remotely to ensure safety.When the new energy vehicles are running,remote monitoring can be carried out to detect whether the electric vehicles have faults at any time,so as to inform users to deal with the faults.The on-board terminal of the electric vehicle transmits data to the server,and the remote monitoring center can conduct data analysis and processing to realize the safety monitoring of the whole vehicle,which is of great significance for the development of electric vehicles.Therefore,through the study and research on the remote monitoring of electric vehicles,aiming at the existing problems of vehicle monitoring,the remote monitoring system of new energy vehicles based on 4G wireless communication is proposed.The main research contents are as follows:1)According to the functional requirements,the overall scheme of the remote monitoring system is designed,which is composed of the on-board terminal system,server,remote monitoring center and mobile phone APP software.2)A remote monitoring center composed of MyEclipse+Tomcat+MySQL5.6 is designed,which can realize the functions of fault alarm,positioning and status data monitoring for vehicles.3)Develop a mobile APP,which can realize real-time monitoring of electric vehicles,and organically combine PC terminal with Android smart mobile.4)The data server of this system is composed of MySQL and Navicat for MySQL,which unifies and effectively manages the data information of electric vehicles.The remote monitoring center can query the database data through the Java language,and display the data information in the browser and mobile phone,so as to realize the monitoring of electric cars.5)To optimize the performance of MySQL database.When the amount of data of electric vehicles in increases,the higher the requirement for the data processing ability of the remote monitoring system database,the optimization of the database can be achieved by adjusting some parameters in MySQL Server,such as connection parameters and cache parameters.The innovation of this paper:1)The monitoring system in this paper can not only realize the view of electric vehicle by logging into the remote monitoring center at the browser end of the computer,but also realize the remote monitoring of electric cars through the APP end of the phone,which realizes the organic combination of the two ways and has the advantages of flexibility and practicality.2)By adjusting the size of default parameters in MySQL,data table structure,adding indexes and other methods to optimize MySQL performance,improve the overall efficiency of remote monitoring system.
