城市轨道交通系统信息共享平台研究

On Information Sharing Platform for Urban Transit System

为了解决城市轨道交通监控系统中的自动化“孤岛”问题,必须建立信息共享平台以实现各个系统间的信息共享及无缝连接。对城市轨道交通信息共享平台的基本功能作了描述,分析了各业务子系统的结构特征和组件技术的特性。城市轨道交通信息共享平台的结构应该是基于公共对象请求代理体系和组件对象模型/分布式组件对象模型技术的。给出了信息共享平台的框架结构以及实现平台功能的基本组件模块。

To eliminate the 'information-island' problem in urban transit supervisory and control systems,it is necessary to establish an information sharing platform,which can ensure information exchange among the supervisory and control systems.This paper introduces the essential functions of information sharing platform for urban transit system,analyzes the structural characters of each supervisory and control sub-system and the distributed object technologies,argues that the information sharing platform for urban transit system shall be esablished on basis of the CORBA and COM/DCOM technologies,which form the frame structure and will help to produce basic modecles of this platform.
