Abstract

Provided is a navigation system using a RFID system and a method for displaying a construction area road. The navigation system includes a RFID tag for storing construction information, and upon receipt of a predetermined command, transmitting the construction information; and a RFID reader for transmitting an information read command to the RFID tag, and receiving the construction information in response to the information read command. A bypass path is re-searched depending on the received construction information, and path guidance is performed.

Claims

1. A navigation system using a RFID (Radio Frequency IDentification) system, the system comprising:

a RFID tag for storing construction information, and upon receipt of a predetermined command, transmitting the construction information; and

a RFID reader for transmitting an information read command to the RFID tag, and receiving the construction information in response to the information read command,

wherein a bypass path is re-searched depending on the received construction information, and path guidance is performed.

2. The system according to claim 1, wherein the construction information comprises construction site, construction period, construction running lane, and bypass road information.

3. The system according to claim 2, further comprising:

an interface unit for performing a data communication with the RFID reader;

a digital multimedia broadcasting receiver for receiving traffic broadcasting information;

a GPS (global positioning system) module for receiving position signals from a plurality of GPS satellites, respectively, and calculating a self position;

a storage unit for storing map data and the traffic broadcasting information under a predetermined control;

a display unit for displaying the map data; and

a controller for mapping the self position to the map data, receiving a destination inputted by a user, searching a path from the self position to the destination, mapping the searched path to the map data, displaying the mapped path on the display unit, performing path guidance along the searched path, and, upon receipt of the construction information from the RFID reader through the interface unit, re-searching the bypass path to bypass a construction site comprised in the construction information, and guiding the re-searched path.

4. The system according to claim 3, wherein, in case where the traffic broadcasting information comprises the construction information and at the time of searching the path, a path search for a bypass road is performed using the construction information, it is checked whether or not the construction information is received from the RFID tag within a predetermined distance from the construction area of the construction information, and, when it is checked that the construction information is not received, a path re-search is performed comprising the construction area.

5. A method for displaying a construction area in a navigation system using a RFID (Radio Frequency IDentification) system that has a RFID tag for storing construction information and a RFID reader connecting with the navigation system and reading and outputting the construction information to the navigation system, the method comprising steps of:

in the RFID reader, periodically transmitting an information read command under control of the navigation system;

in the RFID tag, upon receipt of the information read command, transmitting the construction information;

in the RFID reader, receiving and outputting the construction information to the navigation system; and

in the navigation system, receiving the construction information, and performing a path re-search depending on the construction information.

6. The method according to claim 5, wherein the construction information comprises construction site, construction period, construction running lane, and bypass road information.
