摘　　要：如何克服Web监控系统响应速度慢,页面表达简单,交互性差的缺点,一直是监控系统开发人员不懈努力的目标。基于传统的HTTP请求/响应模式,即使应用AJAX技术实现异步请求和局部页面刷新,依然无法彻底解决以上问题。RIA新技术Flex的出现,为Web监控系统带来了新的革命,采用Flex和数据访问框架LCDS开发的全新Web监控系统经过实际中运用,表现出梦幻般显示效果和高性能数据访问速度,满足了实时监控系统的需要。How to solve the problems of low speed,simple GUI presentation and limited reaction in classic Web Scada is always the destination of automatic controlling system developer.Although AJAX which based on HTTP request/response has solved the web page refreshing with the Asynchronous request and DOM,but above problems still could not be solved completely. The new RIA framework Flex can create engaging,cross-platform rich Internet applications,base on Flex and LCDS the new Web Scada system was designed and implemented in XinYuan Heat-Supplying control system.
