摘要： A monitor image in a monitor region captured by a monitor camera is divided into a plurality of block images, which are inputted to a fire detector constituted by a multi-layer-type neural network so as to detect a fire. A learning image generation device divides a learning image in which a fire in the monitor region is captured into a plurality of block images and classifies the images to fire learning block images, normal learning block images, or non-learning block images based upon the presence/absence of flames and smoke and the ratio at which the flames and smoke occupy in each block image so as to be stored, and a learning control part inputs the fire learning block images and the normal learning block images stored in the learning image generation device to the fire detector so as to subject a multi-layer-type neural network to learning by deep learning process.

摘要： A detector includes a smoke detecting section that includes a light-receiving unit at a position at which the light-receiving unit does not directly receive light emitted by a light-emitting unit in a chamber in which a labyrinth for preventing light from directly entering from the outside and an insect net covering the rim of the labyrinth are provided, the light-receiving unit receiving light scattered by smoke flowing into the chamber. An opening hole is formed open in the surface of the cover receiving hot air current, of the detector. In the cover behind the opening hole, an electrochemical gas sensor is placed to bring gas generated by a fire through the opening hole into contact with an electrolyte solution to detect the gas by an electrode.
