Abstract

PURPOSE:To discover the generation of a flame without fail, to activate a fire extinguishing device and to obtain the using quantity of fire extinguishing agent as necessary and sufficient quantity by using the plural number of the filters of the wave length of the resonance radiating of the flame and the near wave length, detecting respective radiation intensity and calculating the relation between them. CONSTITUTION:As a flame sensor 9 sensor is used to detect plural numbers of spectrums to include a selective radiation spectrum emitted from the flame of a medium infrared band and a means is provide to calculate the intensity ratio of the spectrum. A fire extinguishing is known from the calculated result, the temperature of the extinguished subject can be calculated from the intensity of a gray radiation and this is interlocked with an automatic fire extinguishing device. Thus, the automatic fire extinguishing is possible and simultaneously, it is cleared whether the subject goes down to an ignition temperature or not. Since the consumption of the fire extinguishing agent can be suppressed to the necessary and sufficient quantity, the fire extinguishing agent can be prevented from being wasted and a secondary damage can be limited to a minimum.
