Abstract

L'invention concerne une machine à tunnel RFID utilisant des antennes à faisceaux multiples, comprenant un tunnel de type boîtier, un boîtier de commande et une courroie transporteuse. Un dispositif de commande, un dispositif de lecture-écriture RFID, un module d'alimentation électrique et un circuit de communication sont disposés dans le boîtier de commande ; la courroie transporteuse traverse horizontalement le tunnel de type boîtier ; des capteurs de position sont disposés à intervalles sur le bord supérieur d'une paroi latérale interne verticale du tunnel de type boîtier ; une antenne RFID à faisceaux multiples est disposée sur la paroi interne supérieure, les deux parois internes verticales et la paroi interne inférieure du tunnel de type boîtier. Selon la machine à tunnel RFID, quatre antennes RFID à faisceaux multiples sont utilisées pour lire une étiquette RFID d'un objet transporté sur la courroie transporteuse, ce qui permet de réduire efficacement la possibilité de provoquer une zone aveugle à la lecture et d'augmenter le taux de réussite d'une lecture d'étiquette RFID ; la position de l'objet sur la courroie transporteuse peut être obtenue en temps réel en utilisant des capteurs de position de façon à ce que le dispositif de commande amène, au moyen du dispositif de lecture-écriture RFID, l'antenne RFID à faisceaux multiples à démarrer un faisceau à un angle spécifique pour émettre et recevoir un signal radiofréquence, ce qui permet de réduire les fuites d'énergie et le taux de diaphonie.
