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。
In view of the frequent squibing accidents in water supply enterprises and the serious leakage of pipeline networks, the quantitative analysis of pipeline risks and the visualization of risk assessment results were carried out. Taking Chancheng district water supply network of Foshan as the research object, a standardized database of pipe burst information was established and a calculation method of pipe burst risk value was put forward. The possibility of burst leakage of the main pipe was quantitatively evaluated and introduced Mesh management concept, through the online map API technology, the network risk assessment results in a graphical display on the city map dynamically. This provides an effective visualization solution for the water supply pipe network inspection, pipeline risk warning, pipeline leak detection.
