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。
According to the production organization structure, data flow and business layout of the bus terminal, the traffic dispatch system of the bus terminal is divided into 10 sub-systems. According to the functions and characteristics of each subsystem, the client / server architecture, browser / server 2 kinds of architecture. The component design of the system, the selected small and medium-sized reusable components include database operations components, statistical components, query components, extracted large-size reusable components including planning components, current yard management components and shunting operations plan management components. According to the change frequency of components, the system is divided into four levels: database access layer, business logic layer, process control layer and application system layer. System development using COM component technology, the use of MFC to achieve COM components. The system has been developed and completed in the field station in Chengdu run the test.
