SYSTEM AND METHOD FOR ANALYZING AND MONITORING DEFECTS IN MOVABLE RAIL/TRACK IN REAL TIME USING WIRELESS ACCELEROMETER

摘要

According to one embodiment of the present invention, a system for analyzing and monitoring defects in a movable rail/track in real time using a wireless accelerometer includes: a wireless accelerometer installed on a train; portable measuring equipment obtaining acceleration data generated during driving of the train from the wireless accelerometer; and a monitoring program installed on a monitoring device communicating with the portable measuring equipment in real time, performing analysis with respect to the acceleration data in real time by using short-time Fourier transformation (STFT) and discrete wavelet analysis techniques, and detecting an abnormal place displaying a section in which the defects are generated in the rail/track.;COPYRIGHT KIPO 2020
