System for detecting anomalies |
摘要 |
<p>The invention relates to a method of detecting an anomaly in a mechanical or electromechanical system, comprising: identifying by a processing device, on the basis of a set of spectral components that is generated on the basis of a signal originating from at least one sensor detecting vibrations and/or electrical fluctuations in the system, at least first and second spectral components, each component representing a harmonic or a modulation associated with a candidate component (Ci): by determining a first search window for identifying the first component; by identifying the first component on the basis of the first search window; by modifying the central frequency and the margin of error of the candidate component on the basis of a central frequency and of a margin of error of the first component; and by determining, on the basis of the modified central frequency (Vi) and of the modified margin of error (Ei), lower and upper frequency limits (Vi±Ei) of a second search window associated with the second component.</p> |
