요약
본 논문에서는 무선화재감지기의 효용성 및 신뢰성을 확인하고자, 현재 가장 많이 상용화되어 있는 2.4 GHz의 주파수를 사용하는 무선모듈을 이용하여, 건물 내에서 무선통신 환경에 영향을 줄 수 있는 대표적인 장애물의 종류인 벽체를 시료로 하여 무선신호의 투과파 측정실험을 실시하였다. 실험결과 벽체 종류에 따라 무선신호의 응답특성에 차이가 나타나는 것을 확인할 수 있었다.
Abstract
In this paper, an experiment was performed to confirm the effectiveness and the reliability of the wireless fire detector with a 2.4 GHz wireless module which is widely used for commercial purpose. It was the experiment of transmitted waves of wireless signals using samples of typical obstacles such as walls which may affect the wireless communication environment in the building. The experiment results show that the transmitted signal had differences in the response characteristics by wall types.
Key Words: Effectiveness, Reliability, Wireless fire detector, 2.4GHz frequency, Transmitted wave
