DEVICE AND METHOD FOR DIAGNOSING RFID SYSTEM

PROBLEM TO BE SOLVED: To provide a device and a method for diagnosing an RFID system for automatically diagnosing the entire RFID system and precisely diagnosing a transmission/reception power level. SOLUTION: The system diagnosis device 10 instructs an RW20 to transmit a command for measuring tag operating power. A transmission/reception control unit 25 within the RW20 instructed to transmit a command for measuring tag operating power radiates radio waves having prescribed intensity from an antenna 40 connected to a coaxial cable 30 and measures tag operating power. When a reference tag 45 receives the radio waves, the reference tag 45 transmits the response to the system diagnosis device 10 through the antenna 40 and the transmission/reception control unit 25 of the RW20. A response confirmation/determination unit of the system diagnosis device 10 receives and determines the response, and confirms reception of tag operating power instructed by the command by the reference tag 45 with the minimum power for recording in a recording means (not shown) as a diagnosis power value.
