摘要
爆管关阀分析是供水管网地理信息系统中重要的空间分析功能之一,目前已建系统的爆管分析功能存在着算法繁琐或功能简单、不具通用性等缺点。本文以高质量的源数据为基础,根据系统和爆管分析的需求建立合理的数据模型,设计了爆管关阀分析算法,该算法克服现有算法的不足,剔除了可关可不关的阀门,得到正确、经济的关阀门方案,并列出了受影响的用户。将此设计方案应用于"新疆石油管理局供水地理信息系统"中,成功地实现了爆管分析,体现出了该算法简洁、高效、准确、通用的优越性。
Analysis of pipe burst is one of the most important spatial analysis functions in Water Suply Network Geographic Information System. But the existing system usually has some disadvantages. According the requirement of the system and the analysis of pipe burst and the characteristics of the water supply data, this paper presents the pipe burst algorithm and its implementation, by which we can find out the correct and economical scheme, eliminates the valves that don＇t have to be turned off and lists out the influenced users. This method applies in the ＂ Karamay Water Supply Network Geographic Information System＂ and successfully realizes the analysis of pipe burst. And the result is correct and highly efficient, which proves the validity and feasibility of the method proposed in this paper.
