US 11,148,244 B2 · Vibration spectra window enhancement

Abstract

While monitoring the condition of a machine, vibration data is often collected for analysis by an experienced analyst. Systems and methods for analyzing vibration spectra associated with machine condition monitoring are disclosed herein. A system may be configured to collect vibration data from one or more vibration sensors, generate a vibration spectrum of the vibration data, and generate a spectral plot of the vibration spectrum. The system may receive a selection of a region of the spectral plot and generate a modifiable window of the vibration spectrum that is embedded within the spectral plot. The system may display a set of graphing tools along with the modifiable window that enable a user to make modifications to the window. The system may detect the modifications and update the modifiable window accordingly.

Dependent claims

An apparatus for analyzing vibration spectra associated with machine condition monitoring, the apparatus comprising:

one or more vibration sensors configured to collect machine vibration data;
and
a processor communicatively coupled to the one or more vibration sensors and configured to:
perform a Fast Fourier Transform on the machine vibration data to generate a vibration spectrum that defines an amplitude of a first variable as a function of frequency;
generate a spectral plot of the vibration spectrum for display on a display device, the spectral plot having an x-axis indicative of frequency and a first y-axis indicative of the amplitude of the first variable;
generate a modifiable window within the spectral plot, the modifiable window displaying at least a portion of the vibration spectrum with reference to a second y-axis;
and
receive input from a user interface device that specifies one or both of a change in position of the modifiable window along the x-axis of the spectral plot and a change in scale of the second y-axis.
