Abstract

La présente invention concerne un appareil de contrôle de sécurité auto-adaptatif basé sur un changement de vitesse de transport, se rapportant au domaine du contrôle de sécurité, et comprenant trois parties, c'est-à-dire une unité de base, une unité de balayage et un ensemble mesure de vitesse. L'unité de base comprend une bande transporteuse (1) servant à transporter des marchandises, et un module de logement érigé sur la bande transporteuse (1). L'unité de balayage comprend au moins un groupe de sources de rayonnement logées dans le module de logement, placées selon un angle incliné prédéfini et dirigées vers la bande transporteuse (1), un détecteur monté à l'opposé de chaque groupe de sources de rayonnement, et un module de commande (11) connecté électriquement au détecteur et aux sources de rayonnement. Une unité de mesure de vitesse comprend un capteur de mesure de vitesse monté au niveau d'une entrée/sortie du module de logement. Une mesure de vitesse est effectuée sur la bande transporteuse (1) au moyen de deux groupes de capteurs photoélectriques (12) disposés au niveau de deux côtés d'une structure, puis un courant d'une machine à rayons X (6) est réglé et une fréquence d'échantillonnage d'une carte de détection est commandée au moyen du module de commande, ce qui permet de résoudre le problème du flou d'imagerie d'un système de contrôle de sécurité ou même de l'incapacité d'une imagerie en raison du fait que les appareils de contrôle de sécurité actuels ne peuvent pas réagir automatiquement après un changement de vitesse de la bande transporteuse.
