Microseismic monitoring system having structure of hierachical judgement

摘要

The present invention relates to a micro-vibration monitoring system, and more particularly, to a micro-vibration monitoring system having a hierarchical decision structure for efficiently operating micro-vibration monitoring system resources. A micro-vibration monitoring system having a total determination structure according to a preferred embodiment of the present invention includes a first data collection unit that collects vibration data for each of a plurality of micro-vibration sensors from a plurality of micro-vibration sensors and a first section every preset period. Acquire vibration information in the first time domain by accumulating vibration data during the period, and determine whether the vibration data corresponds to a micro-vibration candidate due to rock damage by analyzing the vibration data for the first time domain and a data collecting device including a first waveform analyzer configured to transmit, to the monitoring device, vibration data in a second time domain for the vibration data determined as a micro-vibration candidate when it is determined that the micro-vibration candidate corresponds to the micro-vibration candidate; and a second data collection unit for receiving vibration data in the second time domain from the data collection device, and by analyzing the vibration data for the second time domain, whether or not it corresponds to minute vibration due to rock damage and a monitoring device including a second waveform analysis unit to determine.
