Application Of Webgis In Cross-grid Business Plan Management System

With the development of national economy,the demand for electricity resources is growing rapidly,making the electricity business expanding.In order to ensure the safe production and the normal operation of electricity enterprises,and improve the supply quality and stability,We need a reliable system in the power sector to product and develop.Application of WebGIS in Cross-grid Business Plan Management System is made based on the current power situation.System uses WebGIS technology to manage spatial information and attribute information of Power Grid project.And it Provides interactive maps and data in the Internet.This article first studies the theory of WebGIS and related technologies,including the architecture of WebGIS,way to achieve,development platform,Spatial Database Engine and so on.And then on this basis,it introduces ArcIMS which is the ESRI's WebGIS solution.Finally from the system design and implementation,it tells us WebGIS's application of Power Grid.This article focuses on finishing the Application of WebGIS in Cross-grid Business Plan Management System with WebGIS technology.The overall system architecture design uses three-tier architecture of WebGIS,that is customer-and application-server and data server layer.Using ESRI's WebGIS solution ArcIMS,application-server layer publishes spatial information of Grid project as a map.Data server layer uses Oracle database to manage attribute data,and uses ESRI's Spatial Database Engine ArcSDE and Oracle database to manage spatial data.In the framework,system has strong ability to deal with the affairs and security and integrate constraints capacity of C / S,and also has simplicity and flexibility of Web.So that it makes the true business-related applications possible.System bases on the overall system architecture design.Design of function components is the core for system development.Function components integrates around the main framework design.Environmental design guides to set up system's physical platform.Ultimately we realizes a WebGIS system of grid-based data.System integrates the spatial information and attribute information of current cross-grid projects,and uses WebGIS technology,database technology and network technology to achieve real-time management and integration of location and attributes information in Power Grid project.Users only need to use IE browser that will be able to view the Grid map,carry out the space positioning of Grid project,and query information conveniently.System increases enterprises's real-time management of cross-grid project,and improves the cross-grid efficiently.So that it has great economic and social benefits.
