Optical Fire Detection System.
Abstract
The invention relates generally to fire detection systems having remote stations coupled to a central analysis station and particularly to a fire detection system having optical fibers which transmit flame signals from remote sensing stations to a central detection and analysis station. The invention comprises a network of optical fibers which connect the monitoring stations to the central detection station for the purpose of transmitting incident analog optical, infrared and ultraviolet spectra to the central station for detection of fire conditions. The central detection and analysis station preferably includes a rotary scanner which scans each of the optical fibers, light from the fibers being detection of the various spectral components of the dispersed light by light sensitive semiconductors. The detected spectral components are then compared to known fire signal signatures which include flicker rate and spectral content information.
