Abstract

Des étiquettes CI (51-525) sont installées pour correspondre aux étagères de réception de charge (11-125) disposées dans un entrepôt, et un dispositif de détermination d’itinéraire de transport (100) auquel un lecteur large bande (210) permettant de détecter les étiquettes CI (51-525) est connecté, est placé sur un chariot-élévateur (7) employé pour transporter une charge. Au milieu du déplacement du chariot-élévateur (7) vers une étagère de destination, le dispositif de détermination d’itinéraire de transport (100) détermine des endroits par lesquels passer selon des codes d’identification d’étiquettes CI détectées par le lecteur large bande (210) et détermine un itinéraire de transport sur la base de conditions prédéterminées formées par combinaison logique des codes d’identification d’étiquette. L’itinéraire de transport pour le chariot-élévateur (7) peut être déterminé avec grande précision même avec des communications exceptionnelles sous l’influence d’une substance réfléchissante etc. rendant impossible la détection de certaines étiquettes CI.
