Description

[0002] Fire is one of the most frequent and destructive disasters. Traditional fire prevention mainly relies on manual patrols, which is ineffective and inefficient, and costly. With the development of science and technology, automatic fire extinguishing and explosion suppression systems for various occasions and various fires are now in large quantities. Fire detectors, as the signal input source of the entire fire extinguishing system, can accurately, reliably and quickly identify fires, which plays a key role in the fire protection capability of the fire extinguishing system. At present, the main types of fire detectors are temperature-sensing fire detectors, smoke-sensing fire detectors and optical fire detectors. When substances burn, smoke, temperature, light radiation, etc. are released. The fastest propagation speed is light radiation, so identifying fires through the spectral radiation of flames is the fastest way of all fire detection methods.
