基于WebSocket和ArcGIS Server的高铁基础设施在线监测系统

为了提高高铁基础设施安全监测的信息化水平,实现监测超标预警的实时性,研究实现了高铁基础设施安全监测管理系统.利用ArcScan进行影像矢量化和属性数据录入,系统业务数据库采用Oracle 11g,并在其中建立基于ArcSDE的空间数据库,通过ArcGIS Sever发布地图服务.系统采用B/S体系结构,利用WebSocket技术实现服务器端和浏览器端的实时通信,调用ArcGIS API for JavaScript开发系统GIS模块,实现了监测超标点实时预警功能.通过在试验工程中的应用表明,该系统实用性强,实现了监测超标的实时预警,具有较高的应用价值.

High-Speed Railway Infrastructure On-Line Monitoring System Based on WebSocket and ArcGIS Server

To improve the informatization level of high-speed railway infrastructure safety monitoring and realize the real-time warning of overproof monitoring data, this paper studies and realizes high-speed railway infrastructure safety monitoring management system. This paper completes image vectorization and attribute data input by using ArcScan. System database of Oracle 11g is used and spatial database based on ArcSDE is constructed within it, then map service is published via ArcGIS Server. Based on B/S architecture, system in this paper realizes the real-time communication between the server and browser, and the functions of GIS module by calling of the ArcGIS API for JavaScript, realizing the real-time warning of overproof monitoring data. Application shows that the system improves the imformatization level of high-speed railway infrastructure safety monitoring, and its practicality is high.
