REAL TIME LOCATING SYSTEM, READER, RFID TAG AND DRIVING METHOD OF RFID TAG FOR LOCATING
First Claim
1. A locating system, comprising:
- a Radio Frequency Identification (RFID) tag outputting a first or second transmission message frame according to whether value added information exists;
a plurality of readers receiving and analyzing the first or second transmission message frame to transmit extracted information and reception time information corresponding to the extracted information to a location processor, wherein the readers are disposed at different locations; and
a location processor analyzing the information which is extracted through the readers and the reception time information to calculate location information or the value added information related to the RFID tag.

Abstract
Provided are a real-time locating systems, a reader, an RFID tag and a driving method of the RFID tag for locating. The locating system includes an RFID tag, a plurality of readers, and a location processor. The RFID tag outputs a first or second transmission message frame according to whether value added information exists. The readers are disposed at different locations, receive and analyze the first or second transmission message frame to transmit extracted information and reception time information corresponding to the extracted information to a location processor. The location processor analyzes the information which is extracted through the readers and the reception time information to calculate location information or the value added information related to the RFID tag.
