Design And Implementation Of Water Leakage Positioning And Monitoring System In Smart Water Management

With the rapid growth of social economy,urbanization is accelerating.However,the water supply management of the water supply company in the jurisdiction has not been improved accordingly.The leakage detection and positioning of the urban water supply pipe network is still facing the water supply company.The two major problems.At present,in the construction of urbanized water supply pipe network,some system tools for monitoring the water supply pipe network have been implemented,but most of them are difficult to detect and locate the leakage of the pipe network.The leakage detection of the pipe network is still through the original method of manual patrol.In view of this situation,this paper proposes a data-driven combined with DMA(District Metering Area)independent metering zone technology and night minimum flow method to realize the control and positioning of pipeline network leakage.The main work of the thesis is as follows:1.Aiming at the current water supply management status of T City,based on demand analysis,a water leakage location monitoring system for the pipe network is designed,which mainly includes four modules: data acquisition module,SCADA module,pipe network model module and water leakage location monitoring.2.By collecting key data such as pipe diameter,pipe material,elevation,etc.,and using the EPANET tool to simulate the hydraulic dynamics of the T city pipe network,and through repeated checks with the monitoring point data,a highly convergent result was finally constructed.Hydraulic model.3.Through the combination of DMA partition management technology,night minimum flow technology,and data-driven technology,the goal of leakage control and leakage location of the water supply pipe network in T City is achieved.4.It is tested and verified by the method of opening and closing the fire valve that in the case of water leakage,the system can more accurately display the flow and pressure changes of the leaking zone,and can locate the leaking location through a datadriven method.Based on the above pipeline network leakage location detection technology,Spring Boot is used as an application development framework to design and develop a pipeline network leakage location detection prototype system according to requirements.The function and performance test results show the availability and stability of the system,and successfully applied to the real environment,realizing the monitoring of the leakage location of the pipe network.
