基于GIS的城市供水管网管线爆管状态实时监测方法

Real-time Monitoring Method for Pipeline Burst Status of Urban Water Supply Network Based on GIS

传统方法在城市供水管网管线爆管状态实时监测中效果不佳,监测结果相对误差大,监测响应时间长,无法达到预期的监测效果。本文提出基于GIS的城市供水管网管线爆管状态实时监测方法。利用无线传感器感知供水管网管线状态数据,提取管线爆管状态特征,并且识别管线爆管状态。利用GIS技术建立城市供水管网管线三维模型,对管线爆管节点定位以及量化管线爆管状态等级,并作出相应的预警监测响应。经试验证明,本方法监测结果相对误差小于2%,响应时间短于2 s,在城市供水管网管线爆管状态实时监测方面具有良好的应用前景。

Traditional methods have poor performance in real-time monitoring of pipeline burst status in urban water supply networks,resulting in large relative errors in monitoring results,long monitoring response time,thus failing to achieve the expected monitoring outcomes.A GIS based real-time monitoring method for pipeline burst status in urban water supply networks was proposed.This study utilized wireless sensors to collect the status data of water supply pipeline networks,extract pipeline burst status features,and identify pipeline burst status.GIS technology was utilized to establish a three-dimensional model of urban water supply pipeline networks,locate pipeline burst nodes,quantify the level of pipeline burst status,and provide corresponding early warning monitoring responses.Through experiments,it had been proven that the relative error of the monitoring results using the design method was less than 2%,and the response time was shorter than 2 seconds.It had good application prospects in real-time monitoring of pipeline burst status in urban water supply networks.
