Patent Images
1. An apparatus for recognizing a location of an object in a location recognition system, comprising:
- a power generating unit configured to generate power;
a signal generating unit configured to generate a call signal including an identifier of a mobile tag so as to search a location of the mobile tag attached to an object;
a signal/power transmitting unit configured to output the power and the call signal;
a magnetic resonance unit configured to transmit the power in a magnetic resonance type and transmit the call signal;
a control unit configured to perform a control to transmit the power and the call signal to neighboring tags;
a signal receiving unit configured to receive identifier information of the mobile tag and location information of the mobile tag corresponding to the call signal through the magnetic resonance unit; and
a location information processing unit configured to recognize the location of the object using the location information.

Abstract
Disclosed are an apparatus and a method for recognizing a location of an object using radio frequency Identification (RFID). The method for recognizing a location of an object includes: activating tags located around radio frequency identification (RFID) tags by transmitting power to the RFID tags in a magnetic resonance type; transmitting a call signal for identifying a mobile tag attached to an object; receiving a tag identifier of the mobile tag corresponding to the call signal; receiving location information from fixed tags around the mobile tag; and recognizing the location of the mobile tag using the location information.
