Coal bunker fire detection device using fiber bragg grating temperature array and processing method

The invention provides a coal bunker fire detection device using a fiber bragg grating temperature array and a processing method, and relates to the technical field of fire detection. The coal bunker fire detection device using the fiber bragg grating temperature array comprises a fiber bragg grating temperature sensing detection system, a transmission system and a signal analysis processing and alarm system, and the fiber bragg grating temperature sensing detection system comprises a protective shell, a light blocking sheet A, a light blocking sheet B and two light blocking sheets C, and four light holes A are formed in each of the light blocking sheet A, the light blocking sheet B and the two light blocking sheets C. According to the coal bunker fire detection device using the fiber bragg grating temperature array and the processing method, two bimetallic strips are arranged to be arc-shaped, when a fire occurs, multiple sets of light holes A can be sealed, the light holes A stop transmitting light, and an
