【摘要】：随着我国铁路运输速度的提升和高速铁路技术的飞速发展,铁路的钢轨安全及钢轨质量受到人们的高度重视。由课题组开发的铁路钢轨监测系统是基于分布式无线传感器网络技术采集铁路钢轨的轨温、应变、加速度等相关信号,以便分析钢轨温度力变化与钢轨振动特性之间的发展规律和变化特点。鉴于地理信息系统(GIS)能够充分展现出分布式无线传感网中监测节点的空间部署特点,本文以项目组搭建的铁路钢轨监测系统为背景开发基于ArcGIS服务软件的Web客户端服务应用。本文主要工作如下： 根据系统的应用环境结合系统特点,设计面向WebGIS服务的铁路钢轨监测系统框架,并重点对方案中的数据存储方法和网络服务管理策略做了详细阐述。 以ESRI公司开发的ArcGIS系列产品为背景,分析地理信息系统中图层的概念及地图的制作过程。结合空间数据库技术,将分布式无线传感网中的节点位置信息绘制成要素图层,并使用ArcGIS Server10服务器对其进行发布和管理。 分析铁路钢轨监测系统的物理和逻辑结构建立系统的数据库服务,并在长期的运行和维护中不断地优化数据库结构,建立满足系统应用需求且结构精简的数据库实体表结构。针对SQL Server2008数据库服务软件,解析数据查询的过程以及数据查询中日志文件的作用。 应用面向WebGIS应用的Silverlight开发平台,完成了Silverlight与.NET平台的数据交互。建立了Silverlight与Web间的数据通道、文件通道和参数通道。其中重点研究跨平台开发中数据库查询的三种方法：基于数据库模型的域服务方式、Windows通讯接口(WCF)服务中的动态连接(LINQ)和在.NET中执行数据库(SQL)查询。 本文开发了在广域网浏览器中对监测路段地理信息、监测设备信息及监测数据的展示系统,并对整个开发过程和结果进行了评述。
[Abstract]:With the rapid development of China's railway transport speed and high-speed railway technology, railway rail and rail safety quality attention. By rail monitoring system developed by the research group is the temperature of rail, the distributed wireless sensor network technology based on the acquisition of rail strain, acceleration signal, in order to analyze the law of development and variations between rail temperature stress and rail vibration characteristics. In view of the geographic information system (GIS) can fully show the monitoring nodes in distributed wireless sensor network and the space deployment characteristics of rail monitoring system based on the project group to build the background of the development based on the Web client service application ArcGIS service software. The main work is as follows:
According to the application environment of the system and the characteristics of the system, we design the rail monitoring system framework for WebGIS services, and focus on the data storage methods and network service management strategies in the plan.
With ESRI developed ArcGIS series of products as the background, analysis of production process and concept map in geographic information system. Combined with the spatial database technology, will draw the location information of nodes in distributed wireless sensor network into the feature layer, and for its release and management using ArcGIS Server10 server.
Analysis of the establishment of system of rail monitoring system of the physical and logical structure of the database service, and in the long run and maintenance to constantly optimize the database structure, built to meet the requirement of system application and simple structure database entity table structure. According to the SQL Server2008 database server software, log file analysis data query process and data query function.
