Abstract:
PURPOSE: A master RFID tag for the administration of physical distribution and a method thereof are provided to enable users to confirm the robbery of products in the middle of circulation steps. CONSTITUTION: A tag reader unit(300) reads information of RFID(Radio Frequency Identification) tag attached to each product stored in a deposit box. A tag information storage unit(310) store the RFID tag information read by the RFID tag. A control unit(330) wirelessly transmits the RFID tag information stored in the tag storage unit to an external RFID reader unit. The tag reader unit is activated by an activation command. The control unit compares the read RFID tag information with the stored RFID tag information.
Abstract:
PURPOSE: An active wireless frequency recognition tag and a location searching method of the same are provided to transmit the sub blink ID information corresponding to the sequence of the sub blink with the sub blink when an active tag transmits the sub blink in a RTLS(Real Time Locating Systems) system, thereby easily performing location calculation by serial arrangement of sub blinks without comparing arrival time information of the sub blink one by one in location processor engine. CONSTITUTION: A location processor engine stores ID information of tag which sent a blink signal, sub blink ID information, and arrival time information of each sub blink(S402). The engine again groups information grouped per tag ID according to each sub blink ID(S404). If the arranged sub blinks are more than three, the engine calculates the location of active tag through the arrival time information of the sub blinks(S406,S408).
