摘要
地理信息系统(GIS)技术的应用,极大提高了城市供水管网的管理水平;现有的基于GIS的城市供水管网管理系统中,爆管关阀分析功能大多不够完善,导致爆管抢修时关闭了一些无需关闭的阀门,扩大了供水影响范围。基于VB+MO的供水管网地理信息系统,通过建立节点数据的拓扑关系,利用广度优先搜索遍历算法,分析阀门间的控制关系、阀门与水源的连通关系,剔除了无需关闭的阀门,得出经济、高效的优化关阀方案。
The application of Geograpfic Information System（GIS） has improved the city＇s water supply network management level tremendously.However,due to the imperfection existed in the analysis function of the valve-closing for pipe burst currently in this system,some of the valves which can still work were closed,and thus widened the demanding influence of the water supply.The VB ＋ MO-based water pipe network geographic information system,which analyses the control and connection relationship between two valves or between valves and sources through the topological relationship of node data and breadth-first search traversal algorithm,eliminates the valves with no need to shut down,drawing an economic and efficient optimized off valve plan.
