基于消息中间件的航班信息显示系统的设计与实现

Design and Implementation of Flight Information Display System Based on Message-Oriented Middleware

基于传统B/S模式的实时信息显示系统通过定时刷新页面方式以实现动态信息的显示,存在效率低、与实际数据不同步等问题。引入基于发布/订阅模式的消息中间件,结合浏览器的插件技术组建航班信息显示系统,系统应用服务器将数据推送给消息中间件,消息中间件再将数据以消息的方式推送给单个或多个目标浏览器,达到动态信息实时显示的要求。测试结果表明,该系统具有页面响应快、服务器资源消耗率低等特点,且随着系统规模的不断增加,性能也能得到保证。

Real-time information display system is based on the traditional B/S mode which requires the user to refresh the page occasionally in order to display dynamic information.The system is inefficient and it is hard for the user to keep pace with the actual data.By means of leading the publish/subscribe model-based message oriented middleware and the browser plug-in technology to build flight information display system（FIDS）,an application server moves the data to the Message-Oriented Middleware,and then the Message-Oriented Middleware moves the data to a single or multiple target browsers.This system can meet the requirement of displaying dynamical information.Test results show that the system has the characteristics of rapid page response and low consumption rate of server resources.
