RFID APPARATUS ADAPTED TO METALLIC MATERIAL

摘要

PURPOSE: An RFID apparatus adapted to a metallic material is provided to obtain sensor measurement value and ID without a battery in facility such as concrete by adding a sensor unit to RFID. CONSTITUTION: A tag(100) includes a measurement unit and a coding mixing unit, and the measurement unit measures sensed physical amount of a sensor unit(300). The coding mixing unit combines an RFID code to the measurement information of the measurement unit. The code mixing unit additionally combines the RFID code to the measurement unit of the measurement unit. The code mixing unit generates a mixing code, and an antenna(200) is connected to the tag. The antenna and the tag are bonded to the one side of the body(400) of the RFID device, and the sensor unit is formed on the other plane of the body.
