采用专人定期定点巡检和抄录的方式进行供水管道漏损检测，不仅运营成本很高，而且很难适应经济飞速发展的需求。需要建立一套经济适用、技术先进、使用简单方便的协同式供水工程自动化监测与控制系统。提供一种基于独立计量区域（DMA）的供水管网漏损在线监测系统，能够掌握水量变化规律与趋势，及时发现管网运行中存在的安全隐患与漏水点，最终达到提高管网运行安全保障与实现漏损控制的目的。%By the means of periodic inspection and record,using manpower to detect the leakage of water supply network not only causes high operation costs,but is also difficult to meet the requirement of rapid economic growth.It is needed to establish a set of affordable,technologically advanced,and easy-using automatic monitoring and control system for coordinated water supply project.In this paper,based on district metering area (DMA)technology,an on-line leakage monitoring system for water sup-ply network is proposed.This system is able to supervise the changing rules and trends of the water,and detect the presence of security risks and leakage points in the pipe network on time.Ultimately the operation security of the pipeline network is improved and the objective of leakage control is realized.
