为提高火电厂输煤设备检修的效率，解决相应软件系统的实时性和便利性问题，提出了以Comet技术为核心的基于Web的设备故障预警图形系统。系统采用Rapha?l来绘制矢量图形，结合基于DOM的脚本编程技术实现了图形系统与用户的友好交互；采用Ajax长轮询方式模拟实现数据信息的服务器端推送，Ajax引擎的异步通讯机制有效解决了页面动态更新问题。在提高信息实时性、降低服务器压力的同时，系统带来了良好的用户体验。

In order to improve the efficiency of mechanical equipment maintenance in the fuel delivery department of thermal power plant, and solve the problems of real-time and convenience in the corresponding software, this paper puts forward a fault alarm graphic system for mechanical equipment based on Comet. In this system, Rapha?l was used to portray vector graphic. Combined with the script programming of document object model (DOM), friendly interoperability of the graphics system was realized. The server-push of data-information was implemented by Ajax long-polling, and the asynchronous communication mechanism of Ajax solved the problem of real-time dynamic refreshment effectively. To improve the real-time information, and reduce the server pressure, the system brings a better user experience.
