Based On The Study Of Infrasound Leakage Zone Transfer Characteristies In The City Water Supply Network

Water is the source of human life, the transport of urban water supply network is playing a vital role in our society, but because of its huge, uncertainties and other factors influenced,the leakage phenomenon often occurs,so we can make a determination about the leakage location quickly and be able to repair timely, which is very important. With the great progress of society, the factors that caused pipeline leakage is more and more, much more people will depend on the water, so the thing that the water supply pipeline leakage area quickly determine has been the most important thing of today’s society.Although there are many apparatus and method at this stage on the application of sound waves to detect pipeline leakage point, but because of their own reasons, there are shortcomings, they can not be real-time, accurate, effective detection position point of leakage to the city water supply network which is based on sonic pipeline leakage, finally, we can get a relatively more comprehensive the system of the leak detection leakage point that the urban water supply network determine, the main is as follows:Firstly it introduces the background of today’s urban water supply pipeline leakage monitoring, as well as its importance and its pipeline leak way, and we can make a careful analysis about the basic principles of real-time detection and location,we focused on the problem of the network formula about the urban water supply.Secondly, through the basic positioning principle analysis of real-time detection of urban water supply networks, we can get two algorithms of urban water supply pipeline leakage positioning (a correlation analysis algorithm, the other is an iterative algorithm), the following is the highlights wavelet analysis algorithms of urban water supply networks in the real-time location monitoring, through the simulation detection approach, and then to determine the effect which the three localization algorithm determine leakage area of urban water supply pipelineAgain, according to the particularity and complexity of the urban water supply network, it is building a testing platform of for urban water supply networks. Through the adding auxiliary sensor in the detection system of the water supply pipe network, thereby it improved the accuracy of the acoustic signal in the pipe network, and improved the detection accuracy and timeliness, we obtained the timing data and the time correction by GPS timing module transmission.Finally, we will make a simulation for their entire city water supply network. By ANSYS software to simulate about the original pipeline signal algorithm in MATLAB software platform, the simulation results show that the system solutions have significantly improved the timeliness and accuracy of detection in urban the cyclic water supply pipeline leakage point.
