Abstract

L'invention concerne un procédé pour vérifier la fonctionnalité d'un système de détection de particules à aspiration (100), en particulier d'un système de détection d'incendie à aspiration pour détecter et/ou localiser un incendie et/ou un début d'incendie, ledit système de détection de particules à aspiration (100) comprenant un système de guidage fluidique (110, 120, 130) qui comporte au moins une conduite de type tube et/ou une conduite de type tuyau (110, 120) débouchant par l'intermédiaire d'une ou plusieurs ouverture(s) d'aspiration (A, B, C,… X) pour prélever respectivement un échantillon de fluide dans une ou plusieurs zones de surveillance (300) ; dans une première étape de procédé (V1), un fluide de test (210) est généré et/ou fourni au moyen d'un générateur de fluide de test (230) qui est ou peut être relié, par communication fluidique, au système de guidage fluidique (110, 120, 130) par l'intermédiaire d'une conduite de fluide de test et/ou d'un raccord de fluide de test (130) du système de guidage fluidique ; et dans une deuxième étape de procédé (V2), le fluide de test (210) est introduit par l'intermédiaire de la conduite de fluide de test et/ou du raccord de fluide de test (130) dans le système de guidage de fluide (110, 120, 130), un écoulement de fluide de test (220) étant généré à l'intérieur de la conduite de type tube et/ou conduite de type tuyau (110, 120) par l'intermédiaire d'un moyen d'écoulement (140, 240). L'invention est caractérisée en ce que l'écoulement de fluide de test (220) à l'intérieur de la ou des conduite(s) de type tube et/ou conduite(s) de type tuyau (110, 120) est dirigé, à partir du générateur de fluide de test (230), dans la direction de la ou des ouverture(s) d'aspiration (A, B, C,… X) de façon que le fluide de test (210) en provenance du générateur de fluide de test (230) entre dans le système de guidage de fluide (110, 120, 130) par l'intermédiaire de la conduite de fluide de test et/ou du raccord de fluide de test (130) et sorte par la ou les ouverture(s) d'aspiration (A, B, C, … X) ; dans une troisième étape de procédé (V3), les temps de sortie réels (tIst,A, tIst,B, tIst,C,... tIst,X) à partir de l'introduction et/ou de l'entrée du fluide de test (210) dans le système de guidage de fluide (110, 120, 130) jusqu'à la sortie du fluide de test (210) par une ouverture d'aspiration (A, B, C,… X) respective sont détectés au moyen d'un chronomètre (150, 250) ; et dans une quatrième étape de procédé (V4), les temps de sortie réels détectés (tIst,A, tIst,B, tIst,C,... tIst,X) sont comparés à un ensemble de données (261) qui est stocké sur un support de données (160, 260) et qui comprend des temps de sortie théoriques et/ou des plages de temps de sortie théoriques (tSoll,A, tSoll,B, tSoll,C,... tSoll,X) associés aux ouvertures d'aspiration (A, B, C,… X) respectives.
