Title:
CONTROL BOARD MONITORING APPARATUS USING VIBRATION SIGNAL
Document Type and Number:
WIPO Patent Application WO/2021/029538
Kind Code:
A1
Abstract:
The present invention relates to a control board monitoring apparatus and, more specifically, to a control board monitoring apparatus using a vibration signal. The present invention comprises: detecting an acoustic signal or a vibration signal generated in a power device, according to a non-contact scheme through a detection unit attached to one side of a distribution control board; analyzing the detected acoustic signal or vibration signal; extracting a signal generated by an harmonic wave in the analyzed acoustic signal or vibration signal; and providing extracted harmonic wave data to a user. Therefore, the present invention can prevent an electrical safety-related accident, such as device burning, short-circuiting, grounding, and electric leakage short-circuiting, which may occur due to sparks when a harmonic wave is measured, and can measure a harmonic wave without a CT or PT sensor or a power analyzer.
