基于CORBA的数字监控网络实时数据服务

Design and Implementation of Real-time Data Service in a Monitoring Network Based on CORBA

结合一个电力监控系统基于服务的设计理念,提出了实时数据服务的设计思想;解决了实现过程中出现的问题;利用面向对象的思想将CORBA事件服务和VisiBroker的多种高级应用(Interceptor,Wrapper)封装在实时数据服务中;应用Interceptor和Wrapper测试了系统性能并分析了实现结果;提出了系统改进的设计思路。

This paper represents the design concept of Real-time Data Service(RDS);analyzes and solves the problems rised in the process of implementation;encapsulates CORBA Event Service and advances application of Visibroker in RDS;measueres the performance of RDS by using Inteceptor and Object Wrapper of Visibroker;advances design thought to improve the system performance.
