列车运行图数据管理系统的研究与设计
|
摘要
列车运行图是铁路运输工作的综合性计划，是铁路行车组织工作的基础。计算机编制列车运行图是铁路运输走向市场的重要措施。通过铁路技术管理工作者和科研院校研究人员的不懈努力，我国铁路在研究运用计算机编制列车运行图方面，已取得了较大成效。各铁路局已基本实现了计算机编制列车运行图。尽管我国的计算机编图研究初步满足了实际编图工作需要，但总的来看，还急需进行深入研究。作为列车运行图系统重要组成部分的的数据管理系统的研究办是如此。目前国内只是在计算机编图系统中提供了数据管理的功能，但面对着众多的、分散的列车运行图数据，如何将这些数据进行有效的管理和运用，为列车运行图的管理提供有效手段，缺乏系统的、整体的研究。利用系统的思想和管理信息系统的设计方法，本论文对列车运行图数据管理系统进行了研究和设计。
主要内容包括：
●对列车运行图数据管理系统进行了分析。
●对列车运行图数据管理系统采用的体系结构进行了讨论。并提出了基于动态Web的分布式应用解决方案，使系统的使用更加灵活方便。
●运用关系数据库原理对列车运行图数据库进行了结构设计，并对列车运行图划分布式数据库的具体实施进行了分析和设计。同时，讨论了列车运行图分布式数据库的数据分片和数据分布。
●对列车运行图数据管理系统进行了系统设计，同时，对列车运行图数据管理系统进行了功能模块设计，为列车运行图的管理提供各种信息服务。
●对列车运行图数据管理系统的实施进行了方案设计，着重对全路列车运行图分布式数据库的建立流程进行了深入讨论。
The train diagram is a integrated plan of railway transportation, and is the base of railway orgnization work .Train diagram computerization is an important measure for marketing railway transportation. With the efforts of the railway managers and researchers, in our country it has maken great progress on the research of Computer Making Train Diagram, Most of the railway bureau have been applying it. Now the research on Computer Making Train Diagram has met the requirement of practical work, taking one with another, it wants to be studied deeply. For the Data Management System of Train Diagram, the part of the Train Diagram System, it' s the same. In our country, only the Computerized Train Diagram System has provided train diagram data management function. But the data, which is numerous and distributed, should be efficiently managed and used, and should provide effective means for train diagram management. We have no systemic and integrated research on it. Based on the system idea and design means of management information system, the dissertation has carried on the research and design of the Data Management System for Train Diagram.
The main research contents are as follows:
1. System analysis on the Data Management System for Train Diagram.
2. Discussing the structure of the Data Management System lor Train Diagram, and proposing a web-based distributed application settlement scheme which bring convenience to the users.
3. The structure design has been underway to the train diagram database on the basis of relationship database rules. And the concrete implementation scheme of Train Diagram distributed database has been analyzed and designed. Further more, discussing the modes of data distribution and location of the Train Diagram Distributed Database.
4. System design and function design, which can provide kinds ol'
information services for the train diagram management, have been carried on to the Data Management System for Train Diagram.
5. Scheme design has been performed to the implementation of the Data Management System for Train Diagram, and it has thoroughly discussed the process of building the Train Diagram distributed database.
