Abstract
The present invention provides a method for signal vibration alert. The method of the present invention recognizes significant substantial swerves and corresponding substantial edge-to-edge differences by eliminating the adverse effect of noise among signals generated by an apparatus. When the frequency of the substantial edge-to-edge differences that exceed an acceptable range of the frequency limit is too large, the method of the present invention automatically generates an alert to indicate aberration in the apparatus such that the monitoring staff is informed and allowed to take necessary measures responding to the aberration.
Claims6
A method for signal vibration alert, comprising:
- collecting a plurality of signals generated by an apparatus within a time interval;
- recognizing a plurality of substantial swerves and a plurality of corresponding substantial edge-to-edge differences based on the plurality of signals, wherein every three consecutive substantial swerves constitute a peak or a valley, each substantial edge-to-edge difference is the edge-to-edge difference between every two consecutive swerves, and each substantial edge-to-edge difference exceeds a predetermined noise range;
- calculating a frequency of the substantial edge-to-edge differences exceeding an acceptable range;
- and
- automatically indicating an aberration in the apparatus when the frequency exceeds a predetermined frequency limit.
