摘　　要：近年来,在智慧城市的大背景下,智慧供水信息化得到了快速发展。通过GIS平台实现了供水管网的可视化展示,并有效集成了SCADA系统、抄表管理系统。在此基础上,研究分析了DMA分区计量系统在供水产销差中的应用,主要内容包括基于国际水协会水量平衡表的产销差分析方法与管控措施、区域已有漏损的分析与评价、区域夜间最小流量分析、区域监测数据关联分析等,提供了区域产销差监控、已有漏损探测、新增漏损预警定位解决方案,对降低供水管网漏损、提高经济效益、保障供水安全和补齐信息化建设短板具有重要意义。Under the background of smart city,smart water supply information has been rapidly developed in recent years.Based on GIS platform,the visualization display of water supply pipe network was realized,the SCADA system and meter reading management system were effectively integrated.On this basis,the application of district metering area(DMA)system in the difference ratio of water supply networks was studied and analyzed.The main content in-cluded the difference ratio analysis method and control measures based on the International Water Association water balance table,the analysis and evaluation of existing leakage in the area,the analysis of the minimum flow at night,and the correlation analysis of regional monitoring data.Solutions for monitoring regional production and sales gap,detecting existing leakage and locating new leakage warnings were provided.It's of great significance to reduce the leakage of pipe network,improve the economic benefit,ensure the safety of water supply and make up the short board of information construction.
