【摘要】：铁路是国家重要的交通基础设施,也是我国国民经济发展的大动脉。加强对铁路运输系统的信息管理,通过数据和信息为决策提供支持,是我国交通运输系统信息化建设的重要内容。河北省铁路运输体系规模较大,情况复杂,在数据管理和网络科学分析方面,传统的数据库和地图方式已经逐渐无法适应。因此,建立河北省铁路地理信息数据管理系统,对河北省铁路信息数据进行现代化综合管理显得尤为重要。河北省铁路地理信息数据管理系统采用基于SuperMap IS.NET的WebGIS技术进行开发,通过地图操作、统计查询和辅助决策三大功能模块,使用户能够快速的浏览、查询相关铁路信息。本文主要从以下几个方面进行了系统的研究:1、介绍了论文选题背景和系统研究意义,对地理信息系统在铁路方面应用的国内外发展状况进行了说明,并阐述了论文的主要研究内容和组织结构。2、概述了WebGIS技术与铁路地理信息数据管理系统相结合的方式,通过比较当前几种主要的WebGIS开发平台,说明了选择SuperMap IS.NET作为本系统开发平台的原因,并对系统开发中的用到的客户端与服务器端的异步数据交换和空间数据库引擎SuperMap SDX+关键技术进行了介绍。3、论述了系统的需求分析和设计原则,提出了河北省铁路地理信息数据管理系统的总体架构。介绍了系统的开发环境,完成了系统数据库的设计。开发了地图操作、统计查询和辅助决策三大功能模块,描述了各模块的主要功能,详细说明了各模块的开发过程。4、介绍了系统的总体界面,通过实例验证了系统三大模块的运行效果并对运行结果进行了说明。
[Abstract]:Railway is an important national transportation infrastructure, and also the artery of national economic development. Strengthening the information management of railway transportation system and providing support for decision making through data and information is an important content of information construction of transportation system in China. The railway transportation system of Hebei Province is large in scale and complex. In the aspect of data management and network scientific analysis, the traditional database and map methods have been gradually unable to adapt. Therefore, it is very important to establish the railway geographic information management system of Hebei province and carry on the modern comprehensive management to the railway information data of Hebei province. Hebei Railway Geographic Information Management system is developed with WebGIS technology based on SuperMap IS.NET. Through the three function modules of map operation, statistical query and auxiliary decision, users can browse and query the relevant railway information quickly. This paper mainly carries on the systematic research from the following several aspects: 1, introduced the thesis selected topic background and the system research significance, has carried on the explanation to the geographical information system in the railroad aspect domestic and foreign development situation. The main research contents and organization structure of the thesis are expounded. 2. The way of combining WebGIS technology with railway geographic information management system is summarized, and several main WebGIS development platforms are compared. This paper explains the reason why SuperMap IS.NET is chosen as the development platform of this system, and introduces the key technologies of asynchronous data exchange between client and server and SuperMap SDX of spatial database engine, which are used in the development of the system. This paper discusses the requirement analysis and design principle of the system, and puts forward the overall framework of the railway geographic information management system in Hebei province. The development environment of the system is introduced, and the design of the system database is completed. Three function modules of map operation, statistical query and auxiliary decision are developed, the main functions of each module are described, the development process of each module is described in detail, and the overall interface of the system is introduced. The running effect of the three modules of the system is verified by an example and the result of the operation is explained.
