摘要
实现全路列车运行图的计算机统一“网上编制”对于增强铁路运输组织工作的灵活性和机动性具有重要意义,是铁路在运输市场中竞争制胜的基础,也是计算机编图适应“网运分离”改革的必然发展趋势。
     本论文在《计算机编制列车运行图系统V2.0》的基础上,针对目前国内计算机编图系统的主要不足——无法安全有效的实现数据信息共享,提出基于B/S体系架构的新型编图系统整体方案,并对处于网络互联状态下、分布式处理系统的列车运行图数据访问权限以及数据传输安全问题进行深入的研究。
     论文的主要研究内容包括:
     ●对目前我国列车运行图管理体制和编制流程进行详细分析,根据其“几上几下”的特点,并结合未来“网运分离”体制改革的变化预测,选择采用与之相适应的基于B/S体系架构、三层业务分布、二层数据分布的整体方案,实现业务与数据的分离,降低开发与应用过程的复杂度和总体成本;
     ●对列车运行图系统的数据信息进行分析,设计符合3NF规范的数据E-R关系模型,并着重研究处于分布式系统中的列车运行图数据信息的访问权限和数据安全问题,提出以视图模式结合用户识别/权限审定实现数据权限划分,以并发处理、容错技术、恢复技术提高系统的数据安全性;
     ●在基于B/S架构的系统整体方案基础上,对当前多种数据传输技术进行分析比较,采用B-ISDN为主干网、ADSL为接入端的基于公用数据网络分组交换技术的系统网络体系结构,并针对网络自身安全性和黑客攻击与侵入问题,详细讨论综合采用差错控制、防火墙、数据加密解密等技术手段提高系统的网络安全性能。
It is significant to fulfill the making of the whole railway train diagram based on corruter networks for the improving of the adaptability and flexility. It is also the foundation for the railway to compete in the transportation market and the certain direction to accommodate the innovation in future.
    This paper focuses on the main limitation - unable to share the data surely and effectively - of the existing systems. On the basis of the Computer Making Train Diagram System Ver2.0, brings fonvard the new style system of making diagram with computer based on the B/S architecture. In the paper, the author makes studies on the data permission security and transport security problems of the Train Diagram System that is based on computer networks and distributed system.
    The main research contents are as follovvs:
    After the analyzing of the process of making train diagram, according with its character, and take into account the trend of innovation, chooses the total solution based on the B/S architecture, 3-tier operation distributed and 2-tier data distributed to separate the data from operation and simplify the development and maintenance;
    The E-R data model that is accord with the 3NF criterion is designed after analyzing the data structure of the Train Diagram System. Emphasis on the permission security of the distributed system, take the view schema, coupled with the login authentication and permissions validation, to ensure the data accessing domination, and take the synchronization, error control, and restore capability to advance the data security;
    On the basis of B/S solution architecture, after comparing the existing transportation technologies, B-ISDN and ADSL is selected as the major solution architecture based on the package-svvitched networks. Furthermore, error control, firewall, and encryption techniques are introduced to prevent the hacker attack and ensure the networks safety.
