客车编组表管理信息系统的研究

Research on a Passenger Train Mashalling Table Management Information System

针对以往客车编组表及车底周转图的生成采用人工整理与绘制的现状,研究和开发客车编组表管理信息系统。系统主要由基本字典管理模块、客车编组表生成模块、客车对数表生成模块及指标计算与信息查询模块组成。通过对Borland的VCL库中的相关基类进行继承和派生,实现客车编组表网格化数据库管理及车底周转图生成与图形操作。其中系统所提供的车底周转图自动生成及人工屏幕调整的功能彻底解决了多重客车套跑的车底周转图勾画难点。

Considering the present status of manually generating passenger train marshalling tables and turnaround diagrams of passenger train set in the past, research and development are done on a passenger train marshalling table management information system. This system is mainly comprised of a basic dictionary management module, a passenger train marshalling table generating module, carriage pairs table generating module and index calculation/query module. By inheriting and deriving the related base class from Borland VCL, the management of a meshed carriage pairs table data bank, the generation of train turnaround diagrams and graphic operation are realized. The functions of automatic generation of train turnround diagrams and manual screen adjustment provided by the system can thoroughly overcome the difficulties in making the train turnround diagram for multiple passenger train extra routes running.
