客运专线列车跟踪定位系统体系结构

Architecture of Train Tracking and Positioning System for Passenger Dedicated Railway

对国内客运专线列车跟踪定位系统的现状和发展进行分析,结合客运专线运输特点,基于逻辑层次化、组件化、面向对象和事件驱动等设计理念,设计系统的体系结构由业务处理层、应用服务层、通信传输层和安全维护层4层构成。在对系统体系结构各层分析的基础上,采用消息中间件技术,构成客运专线列车跟踪定位系统的关键业务层,实现系统关键业务的集成,使得系统具有很好的扩展性和重用性。

The state quo and development progress about the Train Tracking and Positioning System of Passenger Dedicated Railway（PDR）in the country was investigated and studied firstly, then the characteristics of the Passenger Dedicated Railway was combined, with the design vision base. on logic hierarchical, component based, object oriented and event driven, the architecture of the design system was built in four layers including operation processing layer, application service layer, communication transmission layer and safety maintenance layer. On the basis of analysis of the System architecture layers, the information middleware technology was used and thus constructed the key service layer of the Train Tracking and Positioning System of Dedicated Passenger Railway and integrated the pivotal operation components of the System, which made programs better for expansion and reuse.
