Abstract

Microseismic monitoring is utilized for the performance verification and safety management of the structure by detecting fine levels of damage. In order to construct a highly reliable microseismic monitoring system, the role of signal conditioner is critical. The signal conditioner helps with accurate data collection and precision control of the device, and performs additional functions such as signal conversion, linearization, and amplification. In this technical report, noise reduction signal conditioner suitable for mining sites was developed and reviewed for the purpose of implementing more precise monitoring by supplementing the previously developed microseismic monitoring system.

미소진동 모니터링은 구조물의 미세 수준의 손상을 감지하여 구조물의 성능확인 및 안전관리에 활용된다. 신뢰도 높은 미소진동 모니터링 시스템을 구성하기 위해서는 수집된 신호를 변환하는 시그널 컨디셔너의 역할이 매우 중요하다. 시그널 컨디셔너는 정확한 데이터 수집과 기기 정밀 제어에 도움을 주며 신호변환, 선형화, 증폭 등의 추가적인 기능을 수행한다. 본 기술보고는 기존에 개발한 미소진동 모니터링 시스템의 성능을 향상하여 보다 정밀한 모니터링 구현을 목적으로 광산현장에 적합한 노이즈 저감형 시그널 컨디셔너를 개발하고 이를 검토하였다.
