Research On Remote Service System For Electric Vehicle

According to the requirements of the national policy for the development of new energy vehicles,new energy vehicles produced in the future must.be monitored and managed by remote service platform for the operation of key components of electric vehicles.The remote service system of electric vehicle is a system that collects and processes electric vehicle information,and provides information service for network users.A remote service system for electric vehicles with the function of the running data collection,remote transmission,storage and display is designed based on national standards in this dissertation.The main work of this dissertation is as follows:1.The vehicle running parameters collected by electric vehicle remote service system are analyzed from the three aspects of pure electric vehicle structure,performance requirements and related national standards.Then the problems and goals of the system are analyzed and the functional requirements and the framework of the system are proposed.2.The vehicle running parameters including battery data,motor data and trajectory data are collected by communication technology,A multi threshold combined trajectory compression algorithm is adopted to solve the problem of large amounts of redundant data in trajectory data,simulation shows that the error of multi threshold combined trajectory compression algorithm is less;Aiming at the low efficiency of traditional compression algorithm,a MR-TCTCA algorithm is proposed,simulation shows that the MR-TCTCA is more efficient.3.The design of the remote service system is detailed introduced,including vehicle terminal,data center and remote client.And the function of the running data collection,remote transmission,storage and display are debugged...
