摘　　要：铁路调度系统是以列车运行调整为中心,兼顾列车与调车作业的调度指挥和控制系统。我国现有系统正在向着信息密集化系统转变,因此设计一套信息平台,为系统提供公共数据服务成为需要。虚拟共用信息平台是一套整合信息资源,按一定标准完成多元异构数据的接入、存储、分发、整理和挖掘等功能,并面向外部应用提供安全可靠和高效的数据服务的完整物理系统。本文通过对平台四层逻辑结构的详细描述以及对平台实施过程中的关键问题进行探讨,得出信息平台对于统一接口、整合服务、优化数据,具有显著的改善作用;且其实现方式灵活,部署迁移简单,易扩展,适合应用于铁路调度系统,有着较好的发展前景。Centering on train operation adjustment, the Railway Dispatching System was a command and control system taking both train and shunting into account. China＇s current dispatching systems are shift toward information-intensive systems. Therefore, it was needed to design an information platform for the system to provide public data services. Virtual platform for information sharing was an integral physical system that was integrated information resources, implemented functions based on certain standards for multiple heterogeneous data＇s access, storage, distribution, sorting and mining, provided safe, reliable and efficient data services for external applications. Through detailed description of the logical structure of 4-level platform and deep discussion of the key issues in the platform implementation process in this paper, conclusions came out that the information platform had significant improvement for interface unification, services integration and data optimization, flexibility in implementation pattern, simplicity in deploying and migration and being easy to expand. All of these functions showed that the platform was suitable for Railway Dispatching System and had good prospects for development.
