Abstract
A method for determining an operational condition of a vibratory system, comprising receiving vibration signals from one or more sensors associated with the vibratory system preprocessing the vibration signals to remove known noise to create a preprocessed signal, processing the preprocessed signal in both a time domain and a frequency domain to create time domain data and frequency domain data, respectively, and fusing the time domain data and the frequency domain data to determine the existence of abnormal operations.
