基于发布订阅的分布式监控主动消息交互研究

Research of Distributed Monitoring System Active Message Interaction Based on Publish/Subscribe

针对分布式调度监控系统的客户服务器处理效率不高的问题,利用发布订阅消息通信技术,结合公共信息模型,提出了一种分布式监控主动消息交互的新方法;对量测类信息流和控制类信息流进行了实时交互接口设计,融入JMS消息服务器消息主题和发布订阅传输交互模式;该方法在工程中进行了应用,以石德线为算例,进行模拟量和状态量信息的交互实验,完成了单点和多点信息的交互传输,实现了实时变位信息向监控画面的主动即时传输,为分布式调度监控处理提供了一种新的高效实现方法。

Aiming at the problem of client server processing efficiency for distributed dispatching and monitoring system is not high,the use of publish subscribe message communication technology,with common information model,a new method of distributed monitoring active message interaction is put forward.Measurement and control class information flow for real time interactive interface were designed,into Java message server topic message and publish subscribe transmission interactive model.The method has been applied in the project,with dispatching and monitoring system in Shide line as an example,the interactive transmission experimental of Analog and state information is done,single point and multiple point information flow interactive transmission are completed,the active real-time transmission of real-time variable bit information to the monitor screen is realized,A new implementation method of distributed dispatching and monitoring for active message interactive processing is provided.
