Abstract

L'invention concerne un système et un procédé de déplacement et de positionnement d'un objet cible. Le système comprend un lecteur d'identification par radiofréquence (lecteur RFID) à ultra-haute fréquence (1), une étiquette d'identification par radiofréquence passive (étiquette RFID UHF) (2) et une application de compas (3). Le lecteur d'identification par radiofréquence à ultra-haute fréquence (1) est utilisé pour envoyer un signal de fréquence d'onde défini. L'étiquette d'identification par radiofréquence passive (2) peut recevoir et réfléchir le signal, et peut déterminer l'orientation et l'intensité du signal réfléchi en combinaison avec l'application de compas (3). Lorsqu'un signal envoyé par le lecteur d'identification par radiofréquence à ultra-haute fréquence (1) est reçu par l'étiquette d'identification par radiofréquence passive (2), un signal réfléchi est généré, et les indicateurs d'intensité de signal reçu (RSSI) du signal dans différentes directions du compas sont mesurés à l'aide de l'application de compas (3). Il est conseillé de se déplacer vers une direction et de l'approcher avec une forte intensité de signal de façon à positionner correctement l'objet cible (4).
