Title (EN) METHOD OF DETECTING FIRE WITH LIGHT SECTION IMAGE TO SENSE SMOKE
(FR) PROCEDE DE DETECTION D'INCENDIES SENSIBLE A LA FUMEE A IMAGES INTERCEPTANT LA LUMIERE
Abstract: front page image
(EN)The invention refers to a method of detecting fire with light section images to sense smoke. An infrared radiation array (1) and infrared cameras (2) are provided in monitoring area, the images of infrared light spot transmitted by infrared radiation array (1) are transformed into video signal by infrared cameras (2) and transmitted to video switch (3), the video switch sends the received video signal to computer (4) one by one, the computer processes the signal. If the fire is found, the computer controls alarm unit (5) by linkage to alarm.
(FR)L'invention concerne un procédé de détection d'incendies sensible à la fumée à images interceptant la lumière. Un réseau infrarouge et une caméra infrarouge sont disposés dans la zone de surveillance de manière que les images infrarouges projetées par le réseau infrarouge (1) soient transformées en signaux vidéo qui sont à leur tour transmis à un commutateur (3) qui envoie les signaux vidéo reçus à un ordinateur (4) en vue de leur traitement. En cas de détection d'incendie, l'unité d'alerte (5) est pilotée par ordinateur.
