    摘要: A flame detector comprising a flame sensor, a storing section for storing a predetermined reference value, a comparing section for comparing a value of a signal from the flame sensor which changes in amplitude corresponding to a change in flickering of flames with said reference value and adapted to detect flames when the value of said signal exceeds the reference value, and a flame determining section which comprises a computing section for computing a ratio of an amplitude value of a minus change component to an amplitude value of a plus change component of changes in flickering of flames. The storing section stores a preset first threshold value and a preset second threshold value higher than said first threshold value, and the flame determining section signifies the presence of flames is when the ratio of the amplitude values of the signals is larger than the first threshold value and lower than the second threshold value.

    摘要: A system and method for detecting a fire source in a supervised region by means of fire detectors which effectively scan all over such region. A plurality of reference fire sources of the same geometric shape of the minimum size to be regareded as a fire are assumed to be located in successive predetermined position on the floor of the supervised region. Vertical control means successively sets the vertical deflection angles of each detector along the respective straight lines from each detector which graze by the upper end of the respective fire sources and to the lower end of the succeeding fire source. The system also comprises horizontal control means for causing the detectors to horizontally scan the supervised region. Upon detection of a fire, the detectors provide fire detection signals to a central processor unit which then actuates a spray nozzle to direct fire extinguishing fluid on the fire.

    摘要: Apparatus for monitoring the fire extinguishing condition of automatic fire extinguishing equipment which is adapted to detect flames and spray a fire extinguisher liquid from a nozzle to extinguish a fire. The apparatus comprises a detector for generating a signal corresponding to the light energy radiated by the flames and a fire determination circuit for determining that the fire extinguisher liquid is hitting the flames when the detector signal has a DC component but has no AC component, since the AC component corresponds to flicker of the flame and ceases when the fire is sprayed with the fire extinguisher liquid.

    摘要: A flame detecting apparatus and a flame detecting method which utilizes a flame detector having a directivity and provided with a photodetector such as a photodiode or a phototransistor which produces a photo-output in response to the intensity of light incident thereupon. The flame detector is scanned sequentially in the horizontal and the vertical direction within a supervisory region. When a photo-output from said flame detector obtained in the horizontal or vertical scanning by said scanning means exceeds a predetermined threshold value, one of the horizontal and the vertical scanning is suspended, while repeating the other, vertical or horizontal, scanning at the same horizontal or vertical position several times. Flame determination is made when the changes in the photo-outputs, which is obtained through the repeated scanning, exceed a predetermined value and they last over a predetermined scanning angle.
