요약
본 논문은 화재감지는 물론 화원까지 구별할 수 있는 광전식 연기감지기 개발을 위한 기초 연구이다. 이를 위해, 현재 광전식 연기감지기에 많이 사용되고 있는 광원과 센서를 사용하여 광학챔버를 제작하였으며, UL 268에서 연기감지기를 시험할 때 사용되는 세 가지 화원(종이화원, 목재화원, 인화성 액체화원)을 대상으로 각 화원별 광학적 특징을 구하였다. 그 결과 종이화원과 목재화원은 산란에 큰 차이를 보였으며, 인화성 액체화원은 소광의 원인이 다름을 알 수 있었다.
Abstract
This paper is basic study for development of the photoelectric-type smoke detector that is able to distinguish fire source as well as fire detection. For this subject, Light source and sensor which is normally used for the conventional smoke detector are assembled for the optical chamber. Using 3 type of the test fires (the paper fire, the wood fire, the flammable liquid fire) this paper attempts to find optical properties of each fire. These 3 type of fire are used in the testing of smoke detector according to UL 268 standard. As the result, there are disambiguated between the paper fire and the wood fire in scattering and reason of extinction in the flammable liquid fire is different from that of the paper and the wood fire.
Key Words: Smoke particles, Extinction, Scattering, Optical properties
