摘　　要：为提高Browser/Server(B/S)系统告警监视的实时性,通过深入研究同步、异步以及"订阅/发布"3种通信方式,并对异步JavaScript和XML(AJAX)、Comet和Flex 3种技术进行比较,提出了应用Flex技术实现基于web的告警实时显示系统的方法.对Client/Server(C/S)告警实时显示系统及分别应用了AJAX、Comet和Flex技术的B/S告警实时显示系统进行了平均反应时间的测试,结果表明,该法能有效提高B/S系统告警监视的实时性.To improve the real-time performance of browser/server（B/S） system for alarm monitoring, after depth analyzing three means of communications, i. e. , synchronous, asynchronous and “ subscribe/publish”, comparing asynchronous JavaScript and XML （AJAX）, Comet and Flex, a method of implementing,a web-based alarm real-time display system with the use of Flex technology is presented. The average response time is tested on the Client/Server（C/S） alarm real-time display system and the B/S alarm real-time display systems with the use of AJAX, Comet or Flex. The results show that this method can improve the real-time performance of B/S system for alarm monitoring effectively.
