【摘要】 近年来,我国高速铁路实现了跨越式发展,取得了显著成绩,一跃成为世界上高速铁路营业里程最长、发展速度最快的国家。铁路具有明显的地理分布特征,并且在发展过程中产生了大量的铁路空间数据,包括线路、列车、车站、桥梁、隧道、通信信号设备等,需要引入地理信息系统对这些空间数据信息进行管理。本文综合运用数据库技术和WebGIS技术,将Web富客户端开发技术与WebGIS技术有机融合,研究铁路线路数据的有效管理机制。在线路地理模型的基础上,对高速铁路系统所涉及的线路相关数据进行有效组织和管理,并在此基础上开发出高速铁路线路展示系统,实现线路数据的可视化展示和查询功能。论文首先介绍了选题背景及研究意义,分析了我国高速铁路的发展现状及GIS技术在国内外铁路系统中的应用情况,并对系统开发中的相关技术进行了介绍。然后分析了系统的目标用户及系统的功能需求,利用UML给出了系统的用例分析。在需求分析的基础上,提出了系统的总体架构,划分并设计了本系统的各个模块及功能,完成了系统的空间数据库、属性数据库和多媒体数据库的设计。最后介绍了系统开发环境,并详细阐述了系统各功能模块的实现,实例验证了系统的运行效果。本文研究的基于WebGIS的高速铁路线路展示系统对高速铁路线路要素的业务数据及多媒体数据进行管理并提供查询,为列车模拟运行提供二维地图快速展示。本展示系统为WebGIS技术应用于高速铁路信息系统开发做出了有益的探索。更多还原

【Abstract】 In recent years, high-speed railway in China has achieved leapfrog development, made remarkable achievements. China has become the world’s longest high-speed railway operating mileage and fastest growing countries. The railway has distinct geographical distribution characteristics. In the development process of railway, a large number of railway spatial data, including lines, trains, railway stations, bridges, tunnels, communication signal equipment, are generated, which require the introduction of geographic information system to manage spatial data information.In this paper, the database and WebGIS technology were used synthetically. Web rich client development technology and WebGIS technology were combined to study the effective management mechanisms of the railway line data. Based on the line GIS model, high-speed rail system involved relevant line data were organized and managed effectively, and supported by this, high-speed rail line exhibition system was developed, furthermore, line data visualization exhibition and query functions were realized.Firstly, the research background and significance was introduced, the current development of China’s high-speed rail and the application of GIS technology in the domestic and international rail system were reviewed, and related development technologies were introduced. Then, the function and requirements of the target users and system were analyzed. System use case analysis was presented with using UML. Based on requirements analysis, the overall architecture of the system was provided, and the various modules and functions of the system were designed. The design of spatial database system, the property database and multimedia database were completed. Finally, system development environment is analyzed; the implementation of the system function modules was discussed in detail, and the effect of the system operation was explained.The high-speed rail line exhibition system based on WebGIS presented in this paper can realize management and query of the business data and multimedia data on high-speed rail line elements, and display a two-dimensional map of train running simulation. The exhibitionsystem made useful exploration for WebGIS technology used in the development of high-speed railway information system.更多还原
