Design And Implementation Of Operation Monitoring And Leakage Disposal System For Urban Water Supply Pipeline

The water supply pipeline is an important infrastructure of the city,which is related to the quality of daily life water.With the continuous development of urban modernization,the construction scale of urban water supply pipeline is expanding,and the monitoring system of water supply line is becoming more and more complex.The monitoring of traditional water supply pipeline is mainly base on manual work,and there are exist several problems:(1)the measures of running monitoring and management are backward;(2)it is difficult to find and deal with emergencies such as pipeline breakage and burst.In this thesis,the function of water supply system operation monitoring and leakage disposal is realized through software development.The main work are as follows:First,based on the needs of urban water supply pipeline construction,a water supply pipeline model is built around the requirements of water supply pipeline management and water demand,and it is used as an experimental research object.The pipelines include water pumps,electromagnetic valves,various sensors and simulated leakage points,which can simulate a variety of running states of the pipeline more realistically.Secondly,in view of the great economic pressure because of modern city water supply pipeline need to decorate a large number of monitoring points,this thesis optimizes the layout of pipeline monitoring points.The characteristics of the pipeline system model can be expressed by the change correlation between the data of each pressure monitoring node,and the correlation between the monitoring points can be identified through the similarity of the data changes between the pressure monitoring points.In this thesis,the Optics algorithm is applied to cluster the analysis of the spatial characteristic matrix of the pressure node.According to the clustering results,the location and quantity of the pressure monitoring points of the water pipe line can be determined,so as to reduce the optimization effect of the monitoring points.Thirdly,considering that the leakage detection of urban water supply pipeline system is mostly used by manual inspection,it can be found when the leakage position appears more water accumulation,which greatly reduces the efficiency of leakage treatment.In this thesis,the optimized BP algorithm is selected to analyze the pressure data,through the characteristic of abnormal decrease of regional monitoring point data and abnormal change of monitoring value when the water supply pipeline system leaks,the normal fluctuation range of regional monitoring point data is obtained,and the leakage warning is carried out on the regional monitoring points data beyond the fluctuation range.Finally,the operation monitoring and leakage disposal system of the urban water supply pipeline based on the C/S model have been developed in this thesis,which also include detailed introduction of the design of the database.The terminal equipment at the bottom of the system is responsible for collecting the pressure,flow rate and water quality of the water supply pipeline.The data transmission layer realizes the remote transmission and control of data;it combines GPRS technology to realize the rapid transmission of information through short message notification.During the design and development process of the system upper computer,the.net framework 4.0 technology worked as the development platform,C# was selected as the system development language,the design and implementation of login module,data query module,data acquisition module,equipment control module,fault alarm module,terminal communication module,data transmission interface module have been completed.At the same time,the leakage disposal function was carefully studied in this thesis,combined with the optimization function of the Optics algorithm,the leakage judgment function of the PSO-BP algorithm,the selection decision function of the minimum area and the signal transmission function with other function modules,the design of leakage disposal module has been completed,the disposal system of high-efficiency data acquisition function,operation condition judgment function,decision-making method proposed function and scheme implementation processing function were also came true.The operation monitoring and leakage disposal system of urban water supply pipeline has laid the foundation for the scientific,digital and intelligent management of urban water supply pipeline.
