Navigation apparatus and method using RFID
First Claim
1. A navigation apparatus using RFID, comprising:
- an antenna unit that has directivity in a predetermined direction, and is configured to receive at least one radio signal transmitted from at least one RFID tag;
an RFID reader that is configured to convert the at least one radio signal provided by the antenna unit into information on the at least one RFID tag in a digital form, to measure a reception strength of the at least one radio signal, and to provide the information on the at least one RFID tag and information on the reception strength; and
a control unit that is configured to determine a current position and a moving direction on the basis of the information on the at least one RFID tag and the information on the reception strength provided by the RFID reader,wherein the control unit is configured to interlock the current position and the moving direction, with GIS (Geographic Information System) information corresponding to the current position and the moving direction, and to display the current position and the moving direction together with the GIS information.

Abstract
Disclosed is a navigation apparatus and method using RFID that is capable of providing information on a current position and a moving direction to the destination. An antenna unit has directivity in a predetermined direction and receives at least one radio signal transmitted from at least one RFID tag. An RFID reader converts the at least one radio signal provided by the antenna unit into information on the at least one RFID tag in a digital form, measures the reception strength of the at least one radio signal, and provides the information on the at least one RFID tag and information on the received strength. A control unit determines the current position and moving direction on the basis of the information on the at least one RFID tag and the information on the reception strength provided from the RFID reader. Accordingly, it is possible to accurately recognize the current position and the moving direction of the navigation apparatus and guide the moving direction to the destination.

10. A navigation method using RFID that guides a current position and a moving direction to the destination, the navigation method comprising:
-
recognizing at least one RFID tag using an antenna unit and an RFID reader; recognizing the current position of the navigation apparatus on the basis of information on the at least one RFID tag and information on the reception strength of a radio signal transmitted from the at least one RFID tag using the antenna unit and the RFID reader; comparing the information from the at least one RFID tag with a list of RFID tags installed on a moving path to a destination using a control unit; and determining the moving direction of the navigation apparatus using the control unit, wherein the recognizing of the current position includes simultaneously displaying the recognized current position and GIS (Geographic Information System) information corresponding to the recognized current position. - View Dependent Claims (11, 12, 13, 14, 15)
