摘要
Abstract
Considering the problems of great difficulties in resolving pipeline pressure leak signal de-noising, a new method based on singular value decomposition(SVD) is proposed.First, Hankel matrix in original signal is built.Then SVD decomposition of the selected signals is done.The component signals obtained by decomposition are used to find out the sensitive component by using the sensitive factor.At last, the corresponding singular values of the sensitive components are reconstructed by the located factor.The experimental results show that this method, used as a pretreatment of signals, effectively removes the noise of pressure factor of mineral pipeline, which provides a good foundation for pipeline leak detection and location.Furthermore, a comparison is made between wavelet de-nosing and singular value decomposition, the method used in this paper has better de-noising effects.关键词
