METHOD OF ANALYZING VIBRATION WAVEFORM, AND MONITOR FOR MONITORING SLOPE FACE OF BEDROCK

摘要

PROBLEM TO BE SOLVED: To classify a vibration waveform pattern as an abnormal vibration waveform such as rock fall by a neural network, while converting a vibration waveform into a form easily recognized as a pattern. SOLUTION: In this vibration waveform analyzing method of the present invention, a vibration data 1 sampled in every prescribed time is formed inot the vibration waveform data pattern 2, the vibration waveform data pattern is input into the neural network 3 to confirm 5 the minimum error rate while compared with a teacher data pattern 4 registered preliminarily in the neural network, the sampled vibration waveform data pattern is thereby classified as a specified teacher data pattern 6, and it is recognized easily by this manner whether the sampled vibration waveform data corresponds to the issued specified teacher data pattern or not.
