INFRARED FIRE DETECTION SENSOR AND METHOD

摘要

A system and method for detecting radiation indicative of fire, such as forest Fire. In one embodiment, a threshold energy level determined based on ambient sensor conditions. A sensor unit may be setup to scan a predetermined area for electromagnetic radiation (805). Any detected electromagnetic radiation may then be band pass filtered to a wavelength range centered about a predetermined frequency associated with the presence of fire (810). The resulting energy level signal may then be further filter to pass only those signals which exhibit a "flicker" frequency (815). If the resulting filtered signal exceeds the threshold signal (820), fire notification signal may then be generated (825).
