CPC G07C 3/12 (2013.01) [G06F 17/142 (2013.01)] | 6 Claims |
1. A method for identifying abnormal operation of a machine, said method comprising:
generating a monitoring signal in response to behavior of said machine while said machine is in operation;
simultaneously monitoring two or more spectrums in said monitoring signal;
collecting waveform data for two or more spectrums at times when said machine is operating normally to establish an operational baseline of said machine;
identifying a respective energy level in each of the two or more spectrums;
processing waveform data corresponding to each of said identified energy levels into a Fast Fourier Transform radar plot;
determining an area that corresponds to the Fast Fourier Transform radar plot;
correlating changes in said area of said Fast Fourier Transform radar plot with changes in spectrum data and changes in the operation of said machine.
