초록
본 연구에서는 산업현장, 지하시설물의 밀폐공간에서 유해가스 및 생체신호를 동시에 검출이 가능한 휴대형 검출시스템을개발하였다. 개발된 시스템은 가스검출용 센서모듈, 패치형 1채널 소형 ECG 센서, 3축가속도 검출센서용 모듈 및 통계분석용 시스템이다. 시스템모듈의 성능을 검증하기 위해 디지털해상도, 생체신호증폭도, 출력전압 및 초소형모듈의 크기로 평가하였다. 개발된 시스템의 성능결과 디지털해상도는 300(rps), 신호증폭이득은 500dB이상 성능을 가졌고, 심전도 모듈은50mm×10mm×10mm로 제작되어 패치형으로 활용도를 높일 수 있다. 본 연구의 휴대용 가스검출기 및 패치용 심전도, 가속도검출기는 산업현장작업자의 실시간 감시용 IoT 기반 관리시스템으로 활용한다면 가치가 높을 것으로 생각된다.
Abstract
In this study, a portable detection system was developed that can detect harmful gas and signals simultaneously in anenclosed space of industrial sites and underground facilities. The developed system is a sensor module for gas detection,a patch type 1 channel small ECG sensor, a module for three-axial acceleration detection sensor, and a system forstatistics. In order to verify the performance of the system modules, the digital resolution, signal frequency, outputvoltage, and ultra-small modules were evaluated. As a result of the performance of the developed system, the digitalresolution was 300 (rps) and the signal amplification gain was 500 dB or more, and the ECG module was manufacturedwith 50mm×10mm×10mm to increase patch utilization. It is believed that the product of this research will be valuable ifit is used as an IoT-based management system for real-time monitoring of industrial workers.
