摘　　要：根据客运站生产组织结构、数据流程和业务布局,将客运站行车调度系统划分为10个子系统。根据各子系统的功能和特点,采用客户端/服务器结构、浏览器/服务器2种体系结构。对系统进行组件设计,选定的中小粒度重用组件包括数据库操作组件、统计组件、查询组件等,提取的大粒度重用组件包括计划编制组件、现车场管理组件和调车作业计划管理组件等。根据组件的变化频率,将系统从纵向划分为数据库访问层、业务逻辑层、流程控制层和应用系统层4个层次。系统开发运用COM组件技术,采用MFC实现COM组件。该系统已开发完成并在成都站完成现场运行试验。Based on the organization structure, data flow and business layout of passenger station, the train operation and dispatching system of railway large-scale passenger station is divided into ten subsystems. According to the functions and the characteristics of these subsystems, two types of architectures are adopted, which are client/server architecture and browser/server architecture. Component technology is adopted in system design. The medium-small particle reusable components include the database operation component, statistical component, enquiry component and so on. The big particle reusable components include thirteen components, such as plan establishment component, car information on yard management component and shunting operation plan management component, etc. On the basis of frequency change, all components can be divided vertically into four layers, including database access layer, business logic layer, flow control layer and the application layer. Component technology of COM is adopted in the development of the system, and all COM components are implemented by MFC. By now, the system has already been accomplished and tested in Chengdu Station.
