【摘要】：隨著我國鐵路運(yùn)輸速度的提升和高速鐵路技術(shù)的飛速發(fā)展,鐵路的鋼軌安全及鋼軌質(zhì)量受到人們的高度重視。由課題組開發(fā)的鐵路鋼軌監(jiān)測系統(tǒng)是基于分布式無線傳感器網(wǎng)絡(luò)技術(shù)采集鐵路鋼軌的軌溫、應(yīng)變、加速度等相關(guān)信號,以便分析鋼軌溫度力變化與鋼軌振動(dòng)特性之間的發(fā)展規(guī)律和變化特點(diǎn)。鑒于地理信息系統(tǒng)(GIS)能夠充分展現(xiàn)出分布式無線傳感網(wǎng)中監(jiān)測節(jié)點(diǎn)的空間部署特點(diǎn),本文以項(xiàng)目組搭建的鐵路鋼軌監(jiān)測系統(tǒng)為背景開發(fā)基于ArcGIS服務(wù)軟件的Web客戶端服務(wù)應(yīng)用。本文主要工作如下： 根據(jù)系統(tǒng)的應(yīng)用環(huán)境結(jié)合系統(tǒng)特點(diǎn),設(shè)計(jì)面向WebGIS服務(wù)的鐵路鋼軌監(jiān)測系統(tǒng)框架,并重點(diǎn)對方案中的數(shù)據(jù)存儲(chǔ)方法和網(wǎng)絡(luò)服務(wù)管理策略做了詳細(xì)闡述。 以ESRI公司開發(fā)的ArcGIS系列產(chǎn)品為背景,分析地理信息系統(tǒng)中圖層的概念及地圖的制作過程。結(jié)合空間數(shù)據(jù)庫技術(shù),將分布式無線傳感網(wǎng)中的節(jié)點(diǎn)位置信息繪制成要素圖層,并使用ArcGIS Server10服務(wù)器對其進(jìn)行發(fā)布和管理。 分析鐵路鋼軌監(jiān)測系統(tǒng)的物理和邏輯結(jié)構(gòu)建立系統(tǒng)的數(shù)據(jù)庫服務(wù),并在長期的運(yùn)行和維護(hù)中不斷地優(yōu)化數(shù)據(jù)庫結(jié)構(gòu),建立滿足系統(tǒng)應(yīng)用需求且結(jié)構(gòu)精簡的數(shù)據(jù)庫實(shí)體表結(jié)構(gòu)。針對SQL Server2008數(shù)據(jù)庫服務(wù)軟件,解析數(shù)據(jù)查詢的過程以及數(shù)據(jù)查詢中日志文件的作用。 應(yīng)用面向WebGIS應(yīng)用的Silverlight開發(fā)平臺,完成了Silverlight與.NET平臺的數(shù)據(jù)交互。建立了Silverlight與Web間的數(shù)據(jù)通道、文件通道和參數(shù)通道。其中重點(diǎn)研究跨平臺開發(fā)中數(shù)據(jù)庫查詢的三種方法：基于數(shù)據(jù)庫模型的域服務(wù)方式、Windows通訊接口(WCF)服務(wù)中的動(dòng)態(tài)連接(LINQ)和在.NET中執(zhí)行數(shù)據(jù)庫(SQL)查詢。 本文開發(fā)了在廣域網(wǎng)瀏覽器中對監(jiān)測路段地理信息、監(jiān)測設(shè)備信息及監(jiān)測數(shù)據(jù)的展示系統(tǒng),并對整個(gè)開發(fā)過程和結(jié)果進(jìn)行了評述。
[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.
