Fault Diagnosis for Rotating Machinery Using Multiscale Permutation Entropy and Convolutional Neural Networks

Abstract: In view of the limitations of existing rotating machine fault diagnosis methods in single-scale signal analysis, a fault diagnosis method based on multi-scale permutation entropy (MPE) and multi-channel fusion convolutional neural networks (MCFCNN) is proposed. First, MPE quantitatively analyzes the vibration signals of rotating machine at different scales, and obtains permutation entropy (PE) to construct feature vector sets. Then, considering the structure and spatial information between different sensor mea… Show more

“…The results verified the superiority of MPE. In view of the limitations of existing fault diagnosis methods for rotating machinery in single-scale signal analysis, Li et al [ 19 ] proposed a fault diagnosis method based on MPE and a multichannel fusion convolutional neural network (MCFCNN) and verified that this method has high diagnostic accuracy, stability and speed. Compared with PE, MPE is more stable and can be used in a wider range.…”

“…In recent years, the industry has undergone significant development requiring the use of increasingly complex rotating machinery [1] that needs to be monitored and maintained to avoid unplanned shutdowns [2]. Condition-based maintenance (CBM) is, therefore, the tool of choice for monitoring rotating machines' state of health [3].…”
