动态管道风险预警地图的研究与实践

Research and Practice on Dynamic Pipeline Risk Warning Map

针对供水企业爆管事故频发和管网漏损严重的现状,进行了管道风险值量化和风险评价结果可视化表达的研究。以佛山市禅城区供水管网为研究对象,建立了规范的管道爆漏信息数据库,提出了管道爆漏风险值的计算方法,将输水主干管爆漏可能性大小进行定量评价,并引入网格化管理概念,通过在线地图API技术,使管网风险评价结果以图形形式在城市地图上动态展现。这为供水企业的管网巡检、管道风险预警、管道探漏提供了有效的可视化解决方案。

To address serious pipe leakage and frequent pipe burst accidents for water supply enterprises, the pipeline risk value quantification and the visualization of risk evaluation results were researched. In the case of Foshan water supply system, a database of pipe burst information was established, a method of calculating pipeline risk value was proposed, and the probabilities of water supply main burst and leakage were quantitatively evaluated. Moreover, the concept of gridding management was introduced, and the on-line maps API technology was used to exhibit dynamic pipeline risk evaluation results in graphical form on the city map. This provides an effective visualization solution for pipeline inspection, risk warning and leak detection.
