Title
(EN) DETECTOR SYSTEM FOR DETECTING GLOWING PARTICLES
(FR) SYSTEME DE DETECTION DE PARTICULES INCANDESCENTES
Abstract
(EN)
The present invention relates to a detector arrangement (10) included in a preventative, protective system. The sensor lobes of at least two sensor units or sensor sections (10a-10g) are arranged to cover the cross-sectional area of a tubular transport device (8). The arrangement includes a unit (16) for evaluating the output signals of the sensor units (10a-10g), and an activation unit (12) which is adapted to evaluate sensed sub-intensities (10a'-10g') relating to wavelength ranges and each deriving from said sensor units (10a-10g), and to thus co-ordinate received wavelength-related and sub-intensity-dependent signals for calculating and establishing therefrom the relevant disposition of the particle to initiate fire and/or explosion or some other danger.

L'invention concerne un appareil de détection (10) intégré dans un système de prévention et de protection. Les lobes de détection d'au moins deux unités de détection ou sections de détection (10a-10g) sont disposées de façon à couvrir la zone transversale d'un dispositif de transport tubulaire (8). L'appareil comporte une unité (16) d'évaluation des signaux de sortie des unités de détection (10a-10g), et une unité d'activation (12) conçue pour évaluer des sous-intensités (10a'-10g') détectées, relatives aux plages de longueur d'ondes et dérivées desdites unités de détection (10a-10g), et pour ainsi coordonner les signaux dépendants des sous-intensités et relatifs aux longueurs d'ondes reçus, et établir à partir de ces signaux, la disposition appropriée de la particule à initier un feu et/ou une explosion, ou un autre danger.
