Web-based electric vehicle charging station monitoring system and a data acquisition method

Abstract

The invention discloses a Web-based electric vehicle charging station monitoring system and a data acquisition method, comprises a Web external network subsystem, wherein the external network subsystem comprises a real-time library, a Web database, a Web server and a client; the historical data is read from the Web database by the Web server and returned to the client; and the real-time data is obtained from the real-time library by the Web server and returned to the client through a tcp long connection. On the basis of B / S, the invention obtains real-time data from real-time library through tcp long connection, B / S end completes logic processing and realizes picture display with SVG. The browser sends an Ajax data request to the web server. After resolving the request type, the web service obtains real-time data through a long TCP connection or reads the database to obtain historical data and returns. Realize real-time charging and historical data response speed is far higher than theperformance requirements, dynamic data real-time refresh, the normal page screen also shows a high degree of reliability.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to a web-based monitoring system for electric vehicle charging stations. Background technique [0002] Charging stations are used as infrastructure for the development of new energy vehicles, and the country has introduced a series of supporting policies. With the support of policies, my country's charging infrastructure construction has been fully rolled out, and the charging market has become increasingly active. This puts higher requirements on the management and control of charging stations. As a data acquisition and monitoring control system, SCADA system is widely used in various management and control systems including charging station monitoring and management. With the increasing scale of charging stations, more stringent requirements are put forward for the comprehensive performance of SCADA. However, the current SCADA system basically adopts the C / S architectur...
