Abstract: 본 발명은 충돌 타입의 식별 기능을 갖는 RFID 리더 및 그 제어방법에 관한 것으로, RF 통신부에 수신된 신호의 데이터를 분석하여 수신신호의 충돌발생 여부를 확인하고, 해당 RFID 리더와 다른 RFID 리더 또는 태그 중 충돌 발생 수단에 따른 충돌 타입을 진단하여 대응하는 충돌 해결 동작을 수행하도록 한다. 본 발명에 따르면, RFID 리더와 태그 사이에서 발생되는 모든 타입의 충돌에 대한 식별이 가능하므로, 충돌 발생 원인을 빠르게 인지할 수 있어 충돌 발생 원인에 대처할 수 있게 된다. 또한, RFID 리더를 구비한 모바일 어플리케이션에서 충돌이 감지된 경우, 해당 충돌 타입에 대응하는 충돌 제어를 처리함으로써, 이미 시작된 인벤토리 라운드(inventory round)를 성공적으로 종료할 수 있는 이점이 있다.

Abstract: An RFID reader device for situational command retransmission and a control method therefor are provided to recognize the reason for collision occurrence by enabling the recognition for all types of collisions in the procedure in which the RFID reader reads out a tag. An RFID reader device for situational command retransmission includes a collision diagnosing unit(161) and a collision settlement unit(165). The collision diagnosing unit analyzes the data of a signal received during a receiving time by corresponding to a transmission signal from an RF communication unit and diagnoses the collision type according to the analyzed result. Based on the collision type received from the collision diagnosing unit, the collision settlement unit enables the command to be transmitted to the tag through the RF communication unit according to the collision situation. The collision settlement unit includes a command retransmission unit(1651) and a random standby time calculating unit(1652).

Abstract: An RFID(Radio Frequency IDentification) interrogator with a collision diagnostics function and a method for controlling of the same are provided to terminate the inventory round, which has already been started, successfully by processing the collision control corresponding to the collision types. An RF(Radio Frequency) communication unit(130) receives and transmits a signal from and to at least one tag, and a collision diagnosing unit(161) confirms the occurrence of collision of a signal received during a receiving time set up through the correspondence to a transmitting signal from an RF communication unit. The collision diagnosing unit diagnoses collision types according an analysis result of the receiving signal data, and a collision solving unit(165) performs the collision solving operation corresponding to the diagnosed collision type.
