Cascaded variable step LMS filters fused by wave velocity estimation model for leakage localization of water supply pipeline
Water supply pipeline leakage can cause water loss and public health risks. Acoustic sensor-based leak detection methods are promising, but accuracy relies on velocity estimation and signal denoising. This study proposes a leakage location method combining wave velocity estimation models with the cascaded variable step least mean square (VS-LMS) algorithm. Different sound propagation models are used to improve velocity estimation accuracy, and the VS-LMS filter is cascaded to reduce noise in leaked signals. Various estimation models and filtering methods are compared. The TDE achieved −0.66 % positioning accuracy, with discussions on the effects of pipeline pressure and leakage size. This method shows potential for practical engineering applications in detecting water supply pipeline leaks.
期刊介绍:
Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense.
Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems.
Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
