Design Of Electric Vehicle Remote Monitoring And Management System Based On GPRS Technology

With the adjustment and optimization needs of energy structure,the development of electric vehicles is very rapid in recent years.In the whole process of electric vehicle operation,grasp the operating status of the electric vehicle and the performance parameters of each component such as the positioning,speed of the vehicle,the important parameter value of the power battery,the working condition of the vehicle core device unit such as a motor,etc.for the driver,Manufacturers,as well as operation and maintenance personnel and even field scientists are extremely important.According to the actual needs,the author studied and designed a set of remote monitoring and management systems for electric vehicles.The remote monitoring and management system applied to electric vehicles designed by this paper consists of the lower locomotive-mounted data acquisition terminal and the upper computer remote information center platform.The GPRS wireless communication network is used as the transmission medium between the two.Each electric vehicle running on the network collects CAN data(real-time data of key components and battery operating status of the electric vehicle during operation)and GPS positioning data via a data acquisition terminal installed in the car,and uploads the data via GPRS.The network sends these data to a remote information center platform with a fixed external IP address to receive and write into the database.The remote information center platform is deployed on Alibaba Cloud Server and uses J2EE to implement the browser/server architecture.It allows users to register and log in to the platform and send remote monitoring requests.The system uses the MVC architecture to select the correct data to be displayed on the browser according to the content of the request for users to view.In addition,system administrators can log in to the background to manage user information and vehicle information.The article studies and formulates the overall work plan and topology of the system.Completed the hardware system design selection and software flow design,discussed the communication network and developed a complete application layer communication protocol.Based on the JAVA language,it developed a remote information platform that is easy to operate and has a good man-machine interface.Login,background job authorization and various types of information management and other functional modules.The data displayed by the system in real time can provide a good auxiliary function for the operation and maintenance of electric vehicles.In addition,a large amount of historical data stored in the system can also provide economic and dynamic analysis and knowledge discovery of the recent operation of electric vehicles.
