Abstract

In this study, we conducted a low temperature operating test and miniature tunnel model test to study the fire detection capability and properties of an early fire detection system using an optical sensor linear detector that can be installed in harsh environments such as tunnel or utility-pipe conduits which are becoming the major and national infrastructure facilities. The test showed that the optical sensor linear detector was the only one functioned properly among five thermal detectors installed at a low temperature of $-20^{\circ}C$ for 5 days. To study were analyzed adaptability of optical sensor linear detector in the windy tunnel, the operating properties of the optical sensor linear detector when the wind velocity was varied between 0 m/s and 1 m/s in a miniature tunnel model. The temperature change was high when the wind velocity was 0 m/s.

본 논문은 국내 주요 시설 및 국가 기반 시설로 변화되고 있는 터널 및 지하 공동구의 조기화재탐지설비시스템 설치에 이용되고 있는 광센서 선형 화재 감지 시스템에 대한 특성 분석을 목적으로 연구를 수행하였다. 연구 방법으로는 저온 환경인 $-20^{\circ}C$에서 5일간 5가지의 열감지기 중에서 작동 여부를 확인한 결과 광센서 선형 감지기만 작동하는 것을 알 수 있었다. 또한 터널과 같은 풍속이 발생되는 곳을 가정하여 축소 모형 터널을 제작하여 0 m/s와 1 m/s를 변수로 하여 광센서 선형 감지기의 작동 특성을 분석하였다. 그 결과로서 광센서 선형 감지 시스템의 온도 변화에 있어서는 풍속이 없을 때인 0 m/s 때의 값이 높게 나타나는 것을 알 수 있었다.
