초록
Through sprinkler reaction time index (RTI) characterization, the lower the RTI, the faster the sprinkler reacts to fire. The optical properties of an optical fire sensor were combined with a silicon anisotropic etching-process technique to link the fire detection and sprinkler operating time. The sprinkler motion model adopted in this study with sprinkling density was three types: RTI 350, RTI 80, and RTI 80. An optical fiber cantilever-type sensor for fire detection with V-groove support was designed and manufactured. From the analysis results of measurement factors, such as the bending degree of the optical fiber cantilever-type, the frequency variation with the beam length, and the resonant frequency, the cantilever-type sensor can be used as an optical fire sensor for fire detection linking sprinkler RTI.
