THE METHOD TO GIVE PEAK CODES USING OF REGION PARTITION OF FREQUENCY SIGNALS, THE PEAK CODES THEREOF AND THE METHOD TO PREDICT FAULT OF THE MACHINES USING THE PEAK CODES

摘要

A peak code allocating method using a segmentation technique, a peak code and a method of predicting and diagnosing failure of a mechanism using the peak code are provided to compare a normal peak code obtained from the mechanism in a normal state with a measured peak code obtained by analyzing a sound frequency or a vibrating frequency to determine whether the mechanism is out of order. A peak code allocating method using a segmentation technique includes a first step(S10) of collecting an operating sound or a vibrating signal generated when a mechanism operates, a step(S20) of fast-Fourier-transforming the frequency of the operating sound or vibrating signal to indicate the level of the frequency, a step(S30) of confirming whether peaks are located at FFT(Fast Fourier Transform) cells, finding a peak position having the largest peak value and deciding the peak position as a maximum peak value, a step(S40) of indicating the level of the fast-Fourier-transformed frequency on a normal graph, a step(S50) of finding a peak having the largest value from peaks located in a horizontal axis section of the normal graph and deciding the peak as a section peak value, a step(S60) of indicating F which represents the frequency is analyzed to obtain a code, a step(S70) of indicating Y together with the number of segments of the vertical axis of the normal graph, a step(S80) of representing vertical axis coordinates of a normal cell at which the section peak value is located as integers, and a step(S90) of indicating the maximum peak value as numerals.
