基于WebGIS的天然气管网路由系统研究
Research on Routing System for Natural Gas Pipeline Networks Based on WebGIS
摘要
Abstract
With the increasing demand for natural gas,the construction of natural gas gathering and transmission networks is moving towards a networked trend.However,the economic analysis of natural gas network routing is still relatively low,and the visual display effect is unsatisfacto-ry.To address these issues,we built a natural gas network routing system based on WebGIS,which could implement the topological drawing,analysis and evaluation of natural gas network routing.The topological drawing module realizes the drawing of natural gas gathering and trans-mission station and network layers in Svg format under Web and data management and other interactive functions for the network and stations.The analysis and evaluation module combines A*algorithm with the auxiliary network algorithm,proposes the A*-Net algorithm,and realizes the optimal routing query,evaluation scheme generation and visualization.The topological drawing and optimal routing construction model of this system can be applied to other practical problems related to topology analysis,while the analysis and evaluation module can effectively help relevant departments and companies reduce costs when constructing routes.关键词
