Description

Detailed Description of the Invention The present invention is an automatic fire extinguisher that directs the ζ nozzle to the fire source position based on information from a fire source detector that detects the fire source, and automatically extinguishes the fire by emitting extinguishing agent. Regarding equipment.

When the fire detector detects the occurrence of a fire, the inventors of the present application further accurately detect the fire source using a pair of fire source detection devices, and detect the fire source based on the detection information from the fire source detection & fffi. 1) Direct the nozzle to the fire source position according to the Enson and Song Dynasty, and eject extinguishing agent or extinguishing liquid to extinguish the fire. We are proposing equipment,
In this automatic fire extinguishing system, two detectors for detecting fire sources are placed at specified positions with a predetermined interval, and each detector is scanned horizontally to detect the horizontal position of the fire source. However, if the horizontal position of the fire source is the perpendicular bisector of the straight line connecting the positions of the two detectors, the horizontal position of the fire source can be detected accurately. For fire sources located in directions other than on the perpendicular bisector, the accuracy of detecting the location of the fire source decreases when the culm moves away from the perpendicular bisector, and in history, the position of the fire source is If the fire source is located on an extension line directly horizontal to the detector, there is a problem in that the two detectors and the fire source are lined up in a straight line, making it impossible to detect the distance to the fire source.

The present invention has been made in view of the above problems, and aims to provide an automatic fire extinguishing system that improves the accuracy of detecting the location of a fire source and reliably extinguishes the fire.

To achieve this objective, the present invention uses a plurality of fire source detection devices simultaneously scanning vertically and horizontally to detect fire sources.
They are placed on a stand at predetermined intervals, and based on the information from the fire source detection device, the nozzle is directed toward the fire source, and extinguishing agent is emitted to extinguish the fire. and the direction tlr in which rotation control of the gantry in the horizontal yj direction is performed.
