Non-influenced automatic detection of frequencies in spatially located separate parts of the machine

摘要

To provide methods of detecting locations and frequencies of vibrating parts of machines in routine inspection and fault detection of the machines.SOLUTION: A processor implemented method comprises: detecting a set of vibration frequencies by a movement detector; recording at each vibration frequency an output of a stroboscope in the form of a video having a predetermined length; and extracting from the video a frame having a vibrating part corresponding to an associated vibration frequency, and mapping each detected vibration frequency to a corresponding vibrating part using a predefined marker for tracking the associated vibrating part.SELECTED DRAWING: Figure 3
