Title (EN) HIGH SENSITIVITY FIBER OPTIC BASED DETECTION
(FR) DÉTECTION BASÉE SUR DES FIBRES OPTIQUES À HAUTE SENSIBILITÉ
Abstract:
(EN) An integrated communication and smoke detection system includes a fiber harness having at least one fiber optic cable for transmitting light, the at least one fiber optic cable defining a node arranged to measure one or more conditions at a predetermined area. A light source is operably connected to the fiber harness to transmit light along the at least one fiber optic cable to the node. A control system operably coupled to the fiber harness such that scattered light associated with the node is transmitted to the control system, wherein the control system analyzes the scattered light to determine at least one of a presence and magnitude of the one or more conditions at the node. The control system is configured to allow multiple inputs and outputs for communication of information through the fiber harness and node using modulated light.
(FR) La présente invention concerne un système de détection de fumée et de communication intégré qui comprend un faisceau de fibres ayant au moins un câble à fibres optiques pour transmettre de la lumière, le ou les câbles à fibres optiques définissant un nœud conçu pour mesurer une ou plusieurs conditions au niveau d'une zone prédéterminée. Une source de lumière est raccordée de manière fonctionnelle au faisceau de fibres pour transmettre de la lumière le long du ou des câbles à fibres optiques au nœud. Un système de commande est couplé de manière fonctionnelle au faisceau de fibres de telle sorte que la lumière diffusée associée au nœud soit transmise au système de commande, le système de commande analysant la lumière diffusée pour déterminer une présence et/ou une amplitude de la ou des conditions au niveau du nœud. Le système de commande est configuré de sorte à permettre de multiples entrées et de multiples sorties pour la communication d'informations au moyen du faisceau de fibres et du nœud à l'aide d'une lumière modulée.
