METHOD FOR OPERATING A SYSTEM OF RFID, CAPABLE OF PREVENTING RFID READERS FROM NOT CAPTURING TAG INFORMATION OF RFID TAGS

摘要

PURPOSE: A method for operating a system of RFID is provided to successively transmit a transmission-start command and a transmission-end command to RFID readers respectively, thereby reducing a communication load between RFID readers and a server computer.;CONSTITUTION: A server computer successively transmits a transmission-start command and a transmission-end command to each RFID reader based on transmission time allocate to each RFID(S303,S306,S312,S307,S311,S318,S322). Each RFID reader receives tag information from RFID tags from time when the transmission-end command is received to time when the transmission-start command is received. Each RFID reader transmits the tag information of a tag memory to the server computer from the time when the transmission-start command is received to time when the transmission-end command is received.;COPYRIGHT KIPO 2011
