列车运行图是铁路部门全路组织列车运行的基础。本文旨在将WebGIS技术引入列车运行图信息系统,为铁路行车管理提供直观、便捷的网络电子地图辅助决策支持。文章介绍了WebGIS的概念及基本实现技术,提出了基于GISActiveX控件技术扩展浏览器功能,在本地实现列车运行图信息系统GIS操作的方法,从而大大提高系统响应速度,减轻了服务器负担。其中重点阐述了系统框架结构、数据库设计以及实现中的关键技术难点,最后总结了系统的优点及需改进之处。
The train operation diagram is the basis for organizing the entire train operation of the railway department. This paper aims to introduce WebGIS technology into Train Operation Chart Information System to provide an intuitive and convenient network electronic map support decision support for railway traffic management. This paper introduces the concept of WebGIS and its basic realization technology, and proposes a method of expanding the browser function based on GISActiveX control technology to realize GIS operation of train operation diagram information system locally, thereby greatly improving system response speed and reducing server load. The key points of the system framework, database design and implementation are highlighted, and the advantages and disadvantages of the system are summarized.
