【摘要】 列车运行图是铁路列车运行组织的基础，是铁路运输部门的工作计划。自20世纪60年代以来，我国在列车基本运行图的计算机编制方面取得了许多成果，但是由于各种条件的限制，列车实绩运行图的信息化管理还停留在较低的水平。由机务段从列车运行监控装置采集的实绩运行数据，由于没有相应的数据管理机制，目前只能采用文本形式进行处理。为了使这部分列车实绩运行数据在各级管理部门得到更有效的利用，非常有必要建立相应的列车实绩运行图信息管理系统。 本论文就列车实绩运行图信息管理系统的设计和实现进行了研究。论文首先对系统的C/S结构模型进行了分析，提出了系统数据库的分布式设计方案，在此基础上对系统的网络拓扑结构进行了设计；根据系统的功能需求，给出了各功能模块的详细设计；然后，论文论述了系统数据库的设计过程，其中包括安全性设计、事务管理的设计以及ADO数据访问技术的分析及运用。接下来，论文还讨论了列车运行图的绘制实现，重点对绘图数据初始化方法进行了分析设计。最后，论文对系统数据交换功能的设计和实现进行了阐述。 列车实绩运行图信息管理系统的建立，将为机务、调度等部门进行事后分析管理提供新的方法，较大地改善目前列车实绩运行图管理的落后现状。更多还原

【Abstract】 Train graph is the base of railway transportation management and the working plan of transportation department. Since 1960’s, China has made many great achievements in the field of computer-made-base train graph. However, the information management of actual train graph is still in the lower level. At present, train actual data collected from monitor device fixed on locomotives can only be stored in the form of text owing to lack of special data management system. In order to make full use of these data in railway management department at all levels, it is essential to set up a new management information system of actual train graph.This thesis is mainly concerned about how to design and realize a new information management system of actual train graph. The thesis first analyses the Client/Server structure of this new system and puts forward the distribution mode of the system database, based on the new research result, the overall framework of system has been designed. What’s more, the function modules have also been worked out to meet the functional needs of the system.The thesis also analyses the design plan of system database, including its security, transaction management and ADO data access technology. Finally, the thesis discusses some concrete techniques in drawing train graph, particularly focusing on the way of organizing data which are used to draw graphs. The designing of data exchange function has been discussed in the thesis.The new train actual graph information management system can provide some new ways to analyse and manage the train actual running data, and greatly improve the work efficiency of the railway management of different railway departments, such as locomotive and dispatch department.更多还原
