Apparatus and method for providing position information and gathering information using RFID
First Claim
1. An apparatus for generating and communicating road lane hazard data to a vehicle, comprising:
- a plurality of Radio Frequency Identification (RFID) tags installed at consecutive locations within a road lane, each of the plurality of RFID tags consecutively driven by a radio frequency transmitted from an RFID reader installed in the vehicle, wherein at least one RFID tag communicates stored tag information to the vehicle;
a plurality of sensor nodes, wherein each sensor node is associated with a respective RFID tag of the plurality of RFID tags and senses a respective time point when the respective RFID tag is driven and transmits the sensed time point to a sensor network, wherein a plurality of sensed time points and respective RFID tag identifiers comprises traffic data; and
an information gathering server that receives the transmitted traffic data.

Abstract
Provided are an apparatus and a method for providing position information and gathering information using Radio Frequency Identification (RFID). The apparatus includes: a plurality of RFID tags, driven by a radio frequency transmitted from an RFID reader installed in the vehicle, for providing stored tag information in order to provide current position information to the vehicle; a plurality of sensor nodes for sensing the time point when the RFID tags are driven and transmitting the sensed information through a sensor network; and an information gathering server for gathering and processing the information sensed by the sensor nodes, where at least two RFID tags and one sensor node are configured in groups, and the groups are installed at predetermined intervals on each lane of a road.
