针对城镇供水管网漏失水量较大,漏点难以发现的问题,该文提出基于DMA分区计量技术的管网漏损分析系统。系统应用夜间最小流量原理,集合物联网技术、智能感知设备以及计算机网络、云存储等先进信息技术,通过对供水管网流量、压力等参数进行实时监控和分析,实现对管网漏水量和漏点分布的监测和控制,并对供水管网漏损或问题区域快速判断和反应,进而为供水企业持续、稳定地降低漏耗提供技术支撑和数据保障,确保安全供水。系统包含GIS地图、设备实时监测、报表、统计分析、管道设计、漏损方案设计以及系统管理等功能模块。最后通过模拟管网实验验证了系统的可行性和有效性,表明漏损分析系统可分析统计漏损数据及漏损区域,是一种行之有效的技术手段。

Aiming at the problem that the urban water supply network has a large amount of water loss and the leakage point is difficult to find,this paper proposes a pipeline network leakage analysis system based on DMA technology.The system applies the principle of minimum flow at night,integrates Internet of Things technology,intelligent sensing equipment,and advanced information technologies such as computer network and cloud storage.Through real-time monitoring and analysis of parameters such as flow and pressure of the water supply pipe network,the leakage of the pipe network is realized.It can monitor and control the distribution of leakage points and leakage points,and quickly judge and respond to the leakage of the water supply network or the problem areas,so as to provide technical support and data guarantee for the water supply enterprises to continuously and stably reduce leakage consumption and ensure safe water supply.The system includes functional modules such as GIS map,real-time monitoring of equipment,reports,statistical analysis,pipeline design,leakage scheme design and system management.Finally,the feasibility and effectiveness of the system are verified by simulated pipe network experiments.The leakage analysis system is an eff ective technical means to analyze statistical leakage data and leakage areas.
