Abstract

L'invention concerne un procédé pour identifier un ensemble de transpondeurs situés dans le champs d'un dispositif d'analyse, chaque transpondeur ayant en mémoire un code d'identification différent. Le dispositif d'analyse (3) émet des données. Chaque transpondeur (1) non encore identifié compare ces données avec une partie de son code d'identification sélectionnée par le dispositif d'analyse, puis émet dans une fenêtre temporelle choisie en fonction du résultat de la comparaison et de la partie du code d'identification sur laquelle a porté la comparaison. Le dispositif d'analyse (3) reçoit les données émises par les transpondeurs (1) et lorsque celles-ci ne permettent pas de déterminer au moins partiellement leur code d'identification, émet des données modifiées de manière à aboutir, au terme d'un nombre fini d'itérations, à l'émission par les transpondeurs de données permettant de déterminer leur code d'identification.
