Research And Implementation Of Railway Maintainance Production Management System Based On WebGIS

With the development of high-speed rail in 13 th Five-Year planning,China will built a larger,more complete coverage of railway transportation network.In the railway construction constantly enriched and speeded up the premise,the implementation of high-speed railway safety standardization of management requirements will also be higher and higher.Railway maintainance equipments as a railway construction infrastructure for the railway safe operation provides an important guarantee.Therefore,it is imperative to realize the reform of the status of railway maintainance management and make the railway maintainance management be more in line with the development of high-speed railway construction.WebGIS as a network of GIS technology,not only continues the powerful spatial data analysis of GIS technology,but also combines with the Internet,so that users can achieve more intutive operation and browsing the map through the browser.Using the WebGIS technology in the railway maintainance management system,not only make it simpler and more intuitive,through the browser can also provide the railway management staff the overall observation of the railway topographic map,in order to make better decision to offer the effective help.Based on the analysis of the requirements of railway maintainance management system and the research of GIS technology,this thesis future studies the role of GIS in the railway maintainance management and combines with the SSM large enterprise development frame.Using ArcGIS,JQuery,Ajax,HTML5,PostGIS and other related technologies to develop a railway maintainance management system based on WebGIS.Eventually,we realized the informatization management on electronic map.The main contents of this thesis are as follows:1)We analyze the research status of the requirements and GIS technology in railway maintainance management system and some related industries.2)According to the Railway Bureau's requirements of railway maintainance GIS management system,the thesis gave the detailed functional demands and performance demands,then we realized the map service publishing and access as well as the intitutive management of the railway maintainance information devices in GIS.3)Based on the characteristics of railway system spatial data,We gave its storage mode.Also,we analyzed the requirements of business data in railway maintainance system and then we reasonably build business attribute database.4)We proposed a new way of inquiry based on the idea of memory buffer when we inquired the massive spatial data.Then we realized the GPS real-time positioning function and improved the query efficiency in time and space.
