| 摘 要： | 监控系统逐步向B／S框架结构^[1]转变，但由于HTTP协议固有的缺陷，使WEB模式在工业监控实时领域应用一直不尽人意，AJAX技术出现虽然解决了异步通讯和页面刷新问题^[2]，但其依然使用HTTP请求拉方式（Pull）并没有真正解决实时问题。Flex技术和BlazeDS^[3]技术的出现，结合消息服务技术实现的推技术（Push），解决了实时难题，彻底实现了Web实时监控工作模式。

| Abstract: | Automatic control and monitoring system are migrating from C/S to B/S framework at current time,while it is not satisfaction that Web is used in auto-controlling system with the limitation in the HTTP.Although AJAX solve the problem of asynchronization accessing and web page refreshing,but the pull model of HTTP request is still used in communication with server data,the real-time issue is still not realized.With the invention of Flex and BlazeDS framework and combination of Java Message Service,the PUSH da... |
