1. A method for determining an operational condition of a vibratory system, comprising:
- receiving vibration signals from one or more sensors associated with the vibratory systempreprocessing 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.

14. A vibration monitoring system for determining an operational condition of a vibratory system, comprising:
-
one or more sensors configured to output a vibration signal; a preprocessing module operatively connected to the sensors to receive and preprocess the vibration signal, the preprocessing module configured to output a preprocessed signal; a time processing module operatively connected to the preprocessing module to receive the preprocessed signal and to output time domain data; a frequency processing module operatively connected to the preprocessing module to receive the preprocessed signal and to output a frequency domain data; and a data fusion module operatively connected to the time processing module and the frequency processing module to receive the time domain data and the frequency domain data, wherein the data fusion module is configured to combine the time domain data and frequency domain data to determine the operational condition of the vibratory system.
