This is the repository of FaultNet: A CNN for bearing fault detection and classification. The increased presence of advanced sensors on the production floors has led to the collection of datasets that can provide significant insights into machine health. An important and reliable indicator of machine health, vibration signal data can provide us a greater understanding of different faults occurring in mechanical systems. In this work, we analyze vibration signal data of mechanical systems with bearings by combining different signal processing methods and coupling them with machine learning techniques to classify different types of bearing faults. We also highlight the importance of using different signal processing methods and analyze their effect on accuracy for bearing fault detection. Apart from the traditional machine learning algorithms we also propose a convolutional neural network FaultNet which can effectively determine the type of bearing fault with a high degree of accuracy. The distinguishing factor of this work is the idea of channels proposed to extract more information from the signal, we have stacked the ‘Mean’ and ‘Median’ channels to raw signal to extract more useful features to classify the signals with greater accuracy.
There are two datasets that have been used.
- Case Westerm Reserve University Bearing Dataset (CWRU)
- Paderborn University Dataset
