요약
본 연구에서는 다양한 화재실험에서 광학 연기밀도 측정을 위하여 광소멸법을 이용한 저가형 장치가 개발되었다. 저가형 장치의 상대적 측정 정확도는 He-Ne 레이저, 포토디텍터 및 다양한 광학부품을 이용한 고가의 표준장치에 의해 측정된 연기밀도의 비교를 통해 평가되었다. 저가형 장치는 레이저 모듈, 포토셀 그리고 아크릴 보드로 구성되었다. 연기농도의 조절이 용이한 연기 발생장치 실험을 통해, 저가형 장치는 표준장치에 비해 ${pm}10%$의 범위 내에서 연기밀도를 측정할 수 있음을 확인하였다. 저가 장치의 신뢰성은 또한 폴리에틸렌 화염을 이용한 실험에서도 확인되었다. 결론적으로 개발된 저가형 장치는 연기밀도 측정을 위한 간편한 설치 및 실시간 측정과 함께 고가의 표준장치를 대신하여 사용될 것으로 기대된다.
Abstract
A low-cost device using the light-extinction method was developed to measure the optical smoke density in various fire experiments in the present study. The relative measurement accuracy of low-cost device was evaluated through the comparison of optical density measured by a high-cost standard device consisting of He-Ne laser, photo detector and various optical components. The low-cost device was composed of laser module, photocell and acrylic board. From the experiments using a smoke generator can be easily adjusted the smoke concentration, it was found that the low-cost device could measure the smoke density within the range of ${pm}10%$, compared to the standard device. In addition, the reliability of low-cost device was also confirmed in the experiment using a polyethylene flame. Finally, it is expected that the low-cost device developed with real-time measurement and simple installation for measuring the smoke density will be used instead of the high-cost standard device.
Key Words: Optical smoke density, Light extinction method, Low-cost device, Fire safety, Evacuation
