BEDROCK BEHAVIOR DATA PROCESSING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a bedrock behavior data processing system which can analyze waveform data of AE in a short time without any misjudgement and immediately reflect the analysis result on the spot for the safe evacuation of an underground cave. SOLUTION: This system comprises AE sensors (4) buried in the periphery of a cave to be evacuated and a controller (6), which is equipped with an amplifying means (6a) filtering waveform data according to a threshold and amplifying and processing the filtered waveform data, an AD converting means (6c) for converting analog waveform data into digital waveform data, a waveform judging means (6d) judging the waveform data according to a parameter of time and discarding data other than the waveform data of AE, and a waveform analyzing means (6e) analyzing respective characteristics of the waveform data of AE.
