基于GIS的供水管网系统爆管分析研究

Study on Analysis of Pipe Burst of Water Supply Pipeline Network System Based on GIS

为优化供水管网信息化不足和解决爆管突发事件发生后如何快速关阀等问题,在已有的GIS基础上,设计了一套供水管网系统,实现供水管网的可视化管理,优化了供水管网管线布局,解决了信息化水平不足等问题。同时,采用图论原理,将供水管网抽象为有向网络图,模拟展示爆管事件发生后影响区域范围,提出一种快速定位所需关闭的上流阀门算法。经用例测试,系统不仅能可视化地管理城市的供水管网数据信息,在爆管事件发生后,还能为抢修人员快速制定精确、高效的关阀策略。

For the purpose of optimizing the informatization of the water supply network and turning off the valve quickly after the sudden pipe burst, This paper develops a water supply network geographic information system based on GIS to achieve visual display. In this way, the layout of the water supply pipeline is rationalized and the informatization is improved. At the same time, the paper converts the water supply pipeline network into an abstract directional graph based on the principle of graph theory,simulates the area affected by the pipe burst and puts forwards a calculation way to quickly locate the valve that needs to be turned off. With a series of tests, the system can help manage the data of the city’s water supply pipeline in a visual way, and help the repair men to quickly come up with the accurate and efficient measure to turn off the valve.
