摘　　要：为满足能量管理系统(EMS)中Web服务对高实时性的需求,文章提出了一种使用WebSocket技术的解决方案。应用WebSocket技术,Web服务器和浏览器端可以维持一个全双工的长连接,服务器端利用该连接能实时地向浏览器端"推送"数据。这种方式解决了传统Web应用中"请求-问答"式通信带来的信息延时和信息丢失的问题,满足EMS系统中某些高实时性应用的要求,最后以EMS系统实时告警浏览模块的架构实现为例介绍了如何应用WebSocket技术。Due to the demand for high real-time information in EMS system, this paper presents a WebSocket technology solution. Using WebSocket, Web server and browser can maintain a long connection of full-duplex. With this connection, Web server can ＂push＂ the real-time information to a browser. This solution can solve delay and loss of information due to the using of a ＂Q ＆ A＂ type communication, and it meets the requirements of the EMS system in real-time applications. Finally, as an example, an architecture of EMS system real-time alarm browsing application based on Websocket technology is provided.
