基于内禀模态奇异值熵的声发射管道泄漏诊断
Pipeline Leakage Detection Based on Singular Value Entropy of IMFs
摘要
Abstract
Pipeline leakage diagnosis is the precondition of leakage location.A new method based on singular value entropy of Intrinsic Mode Functions (IMFs)is proposed aiming at the non-stationary characteristic of the acoustic emission (AE )signal from pipeline leakage for leakage detection.The IMFs is obtained by EMD from AE signal,and the initial feature vector is composed by IMFs.The singular value entropy of the vector is used for leakage detection. Simulation and experiments indicates the effectiveness of the proposed method.关键词
