摘要
随着天然气需求的不断增加,天然气集输管网建设正呈现网络化趋势。然而,天然气管网路由的经济效益分析仍较低,且可视化展示效果不佳。针对上述问题,基于WebGIS构建了天然气管网路由系统,实现了天然气管网路由的拓扑绘制、分析和评价。其中,拓扑绘制模块实现了在Web下绘制Svg格式的天然气集输站点和天然气集输管网图层,并实现了管网和站点的数据管理和其他交互功能。分析和评价模块则采用了A*算法和辅助网络算法的融合,提出了A*-Net算法,实现了最优路由查询、评价方案的生成和可视化。该系统的拓扑绘制和最优路由搭建模型可应用于其他有关拓扑分析的实际问题,而分析和评价模块的应用可以有效帮助相关部门在建设路由时降低成本。
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 unsatisfactory.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 transmission 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.
