Definitions

  • the invention relates to a method and a device for processing broadcasts with radio transponders in a transmission processing system when using a metal detector located on the transport path, which generates a signal for rejecting this transmission when the metallic transmission content is detected.

  • radio transponders Upstream of the transport path in front of the metal detector, radio transponders are detected, a signal to the metal detector being delayed and being emitted over a minimum period of time, depending on the distance of the metal detector from the location of the front edge detection and depending on the transmission speed, when the radio transponder and the detected front edge are detected, which reliably prevents a metal detection signal.
  • the radio transponder detector has an antenna and a high frequency generator connected to the antenna, which are both tuned so that a field with the operating frequency of the radio transponder is emitted.

Abstract

L'invention concerne le traitement de courriers (1) comprenant des transpondeurs de diffusion dans une installation de traitement de courrier (4), dans un détecteur de métaux (4) se trouvant sur une voie de transport (2), lequel produit un signal permettant d'éliminer ledit courrier (1) lorsqu'un contenu de courrier en métal est reconnu. L'objectif de l'invention est d'éviter l'élimination des courriers au moyen du transpondeur de diffusion. A cet effet, des transpondeurs de diffusion sont détectés sur la voie de transport (2) avant le détecteur de métaux (4) dans le sens du courant. Lorsqu'un transpondeur de diffusion est reconnu et qu'un bord d'attaque d'un courrier est détecté, un signal est temporisé en fonction de la distance du détecteur métallique (4) et de l'endroit de détection de l'extrémité du bord d'attaque du courrier et en fonction de la vitesse du courrier, puis le signal est envoyé sur une période temporelle minimale, ce qui permet d'éviter un signal de reconnaissance des métaux.
