Abstract: 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.
