RFID READER WITH READER ANTI-COLLISION PROTOCOL AND OPERATE METHOD THEREOF

摘要

The present invention discloses an RFID reader and a method of operating the RFID reader to which the reader duration conflict prevention protocol is applied. That is, a slot setting module for selecting an arbitrary slot among N time slots and setting the selected slot as a driving time, a channel setting module for selecting an unused channel among N channels including a promised common channel, A sensing module for recognizing a sensing signal received from an external reader via the N channels and a communication module for transmitting a sensing signal through the set driving region during the set driving time, As a part of the base reader collision prevention protocol, it is shown that there is no Hidden Terminal Problem in 'Pulse' and all kinds of reader collision can be solved even in a environment where a reader moves using a multi channel while using a beacon message.;RFID reader, collision
