Abstract

L'invention concerne un procédé simple et économique de surveillance individuelle de produits en vrac (1-1, 1-2, 1-3). Selon ledit procédé, une surveillance individuelle de produits en vrac (1-1, 1-2, 1-3) est effectuée au moyen d'un transpondeur (2-1, 2-2, 2-3; 20). Ce dernier est placé sur les produits en vrac (1-1, 1-2, 1-3) et comprend au moins un capteur (21), destiné à relever au moins un paramètre d'état des produits en vrac (1-1, 1-2, 1-3), ainsi qu'une mémoire (22) accessible en lecture et en écriture par un appareil de lecture/écriture (3). Une lecture répétée du transpondeur (2-1, 2-2, 2-3; 20) est effectuée par l'appareil de lecture/écriture (3). A chaque opération de lecture, ledit au moins un paramètre d'état est relevé par le capteur (21) du transpondeur (2-1, 2-2, 2-3; 20) et transmis à l'appareil de lecture/écriture (3). Le paramètre d'état transmis à l'appareil de lecture/écriture (3) est transformé en au moins un paramètre de résultat par l'appareil de lecture/écriture (3) et enregistré dans la mémoire (22) du transpondeur (2-1, 2-2, 2-3; 20), lors d'une opération d'écriture, de façon à pouvoir être lu et/ou effacé. On obtient ainsi un enregistrement journal lisible à tout moment, qui permet de tirer des conclusions sur des états antérieurs des produits en vrac (1-1, 1-2, 1-3).
