Research On Leakage Monitoring Of Water Supply Network Based On Wireless Sensor Positioning

Water resources are one of the important resources in human production and life,and are widely used in industry,agriculture and life.At present,the shortage of global water resources has threatened most countries and brought severe challenges to the economic,social and technological development of all countries.China,which is considered to be rich in water resources,has now only 2140 m~3/person per capital water resources in the country,and has become one of the countries with severe water shortages.Water shortage has become a bottleneck restricting the sustainable development of my country’s economy.The water supply network is one of the important measures to solve the urban water supply problem,and it plays a pivotal role in ensuring the normal operation of society.However,due to the long-term use of the water supply pipe network,some parts of it have been decayed,aging and deformed,resulting in continuous leakage of the water supply pipe network,which largely caused the loss of water resources.According to statistics,the leakage rate of the water supply pipe network has been It is as high as 15.6%and it is increasing year by year.For this reason,the establishment of an intelligent water supply pipe network leakage monitoring and positioning system has very important practical significance to achieve the purpose of timely positioning and timely detection of leakage points in the water supply pipe network.Wireless sensor network has the characteristics of low power consumption,low cost and high accuracy.This paper uses wireless sensor network technology to design a water supply pipeline network leakage monitoring system.The system monitors the physical parameters of water supply pipelines such as vibration,water pressure and water flow,and realizes The sensor node location,the monitoring data and location information are transmitted to the monitoring platform for storage and processing,in order to achieve the goal of real-time monitoring and positioning of the water supply pipe network and timely detection of water leakage,and then the paper from the two aspects of hardware design and software design The designed leakage monitoring system of the water supply network is analyzed in detail.Based on the water supply pipeline network leakage monitoring system designed based on wireless sensor network technology,this paper solves one of the key technologies of the system,wireless sensor network positioning technology.Combined with the application environment of the system designed in this paper,a DV-Hop positioning algorithm based on SAPSO algorithm and RSSI optimization is proposed.First,it analyzes several key positioning algorithms of wireless sensor network positioning technology,and then selects the DV-Hop positioning algorithm based on the implementation environment of the system in this paper,and optimizes the DV-Hop positioning algorithm from two perspectives,using RSSI ranging technology and smart group Algorithm SAPSO optimizes the positioning algorithm in this article to improve positioning accuracy.
