The Design Of Vehicle Charging Station Management System

Electric vehicles,using renewable and clean electricity as the power source,are sustainable,and have become the focus of the development of all countries in the world.Building a reliable,efficient and safe electric vehicle charging station is an important part of popularizing electric vehicles.At present,the established demonstration charging stations often rely on manual management,low efficiency and error prone.Research and development of a set of WEB based,unified interface,highly automated operation and maintenance management platform,can improve the reliability of equipment operation,reduce maintenance costs,reduce the burden of monitoring center.The development of modern instant computer technology,communication technology,control technology and information management technology provides an effective way to solve this problem.According to the construction mode and function requirements of several stations for electric vehicle charging station operation management platform no uniform communication protocol of electric vehicle charging,the design and implementation of electric vehicle TCP/IP Guan Liping station operation and maintenance of Modbus protocol and IEC60870 protocol based on charging.The overall design of the management platform,the electric vehicle charging station for electric vehicle charging station management mode,operation characteristics,industrial monitoring,monitoring protocol commonly used software development languages and platforms,proposes the B/S framework of electric vehicle charging station operation management platform based on the design of the electric vehicle charging station construction,operation and maintenance management platform database communication front-end processor,man-machine interface.The operation and maintenance management platform of electric vehicle charging station is composed of communication pre processor,alarm server,database server and web server.The communication front-end communicates with a plurality of charging stations or discrete charging piles through the IEC60870 protocol or the Modbus protocol,collects real-time data,and sends control or setting commands.The alarm server realizes the sending of the alarm,and can send the alarm in time and accurately,so as to improve the efficiency of solving the problem.The database server is responsible for storing historical data and related configuration information,providing data support for the entire system.Web server processing human-computer interaction interface,including real-time data display,GIS geographic information display,real-time alarm information display,historical data statistical analysis,basic information management functions.Finally,the paper tests and optimizes the operation and maintenance management platform software of the electric vehicle charging station.After testing and practical application,the system achieves the expected design performance indicators and functional indicators.
