Abstract

L'invention concerne un procédé de surveillance d'une circulation de produit pour détecter un processus de chargement, comprenant au moins les étapes suivantes consistant à : détecter la réception d'un produit au moyen du dispositif de transport par lecture d'une étiquette de produit associée au produit au moyen d'un dispositif de lecture associé au dispositif de transport ; surveiller l'état de chargement du produit sur le dispositif de transport par lecture répétée ou continue de l'étiquette de produit associée au produit au moyen du dispositif de lecture associé au dispositif de transport ; détecter que le dispositif de transport transportant le produit est entré dans une zone de chargement de l'unité de réception de produit par détection d'une traversée d'une région de géorepérage qui délimite la zone de chargement au moyen de l'étiquette de dispositif de transport associée au dispositif de transport et/ou au moyen d'une étiquette d'unité de réception de produit associée à l'unité de réception de produit ; détecter que le produit a été déposé par le dispositif de transport lorsque l'étiquette de produit associée au produit ne peut plus être lue par le dispositif de lecture associée au dispositif de transport ; et détecter que le dispositif de transport ne transportant plus le produit a quitté la zone de chargement par détection d'une traversée de la région de géorepérage qui délimite la zone de chargement au moyen de l'étiquette de dispositif de transport et/ou au moyen de l'étiquette d'unité de réception de produit.
