Abstract: 본 발명은 패시브 태그의 전력관리장치 및 방법을 개시한다.
본 발명에 의하면, RFID 리더로부터 전송되는 RF 신호를 수신하고, 수신한 RF 신호의 세기를 측정하며, 측정된 RF 신호의 세기를 바탕으로 RF 신호에 의해 여기되는 전력이 태그를 구동하기 위한 수준 이상인가에 따라 태그에 내장된 전력공급수단으로부터 공급되는 전력이 혹은 RF 신호에 의해 여기되는 전력이 태그에 공급되도록 하여, 태그는 물론, 전반적인 RFID의 송/수신 시스템의 전력 소모에 있어 보다 높은 효율성을 기할 수 있고, 더 나아가서는 상기한 명령어 셋트가 필요없는 만큼 데이터 양이 줄어, 이에 따라 데이터 처리가 간편해지는 효과가 있다.-

Abstract: A communication method for the RFID is provided to make a tag immediately transmit additional data through a response message by transmitting a command message including a command code, the kind of additional data and an identifier for distinguishing the response format and tag. A random value issued as the identifier of a tag is transmitted to an RFID(Radio Frequency Identification) reader(S501). A command message is received from the RFID reader(S502). The state of the tag is changed into an ACK mode(S504). Based on the response format of the received command message, additional data is inserted into a response message(S505). The response message is transmitted to the RFID reader(S506).

Abstract: A method and a mobile RFID reader which controls TDMA of a mobile RFID reader through a mobile base station are provided to prevent interference between readers by occupying a channel during a time slot and frequency allocated in the mobile RFID reader. A mobile RFID(Radio Frequency Identification) reader requests a channel for RFID communications with a tag as a base station through the uplink channel according to the protocol of the mobile network(S610). The base station assigns the channel information of the transmission channel and transmit window to the mobile RFID reader through the downlink channel according to the protocol of the mobile network(S630). The mobile RFID reader performs the tag selected according to the channel information in the allocated frequency channel for the designated time slot(S650). The mobile RFID reader transmits the history information collected for the inventory round to the base station after the inventory round termination(S670).

Abstract: A device and a method for transmitting a sensor status in an RFID(Radio Frequency IDentification) tag are provided to remove additional communication between an RFID reader and the RFID tag by transmitting sensor data and/or status information of each sensor embedded in the RFID tag in addition to a tag ID of the RFID tag. More than one sensor(151) detects and measures physical change of an external environment. A memory(157) stores measured sensor data and status information of each sensor. A message generator(159) generates a response message including a tag ID, and at least one of a status record and data formed based on sensor status information. A controller(155) generates a signal for controlling measurement operation of the sensors and forming the status record. The status record is formed by status information of all or predetermined sensors depending on a request of an RFID reader(100). The status record includes at least one of the number of sensors, an internal port number of the sensor, sensor monitoring activation, sensor alarm function activation, alarm generation/condition, time stamp storage, a scheduling mode, sensor property, and error information.

Abstract: An apparatus and a method for generating a wake-up signal of a passive tag having a battery are provided to adjust a life span of a battery or a tag by generating a wake-up signal which operates the battery in response to a signal of an RFID(Radio Frequency Identifier) reader. An apparatus for generating a wake-up signal of a passive tag having a battery includes a signal detection unit(200), and a control unit(250). The signal detection unit generates a wake-up signal if an input signal is an activation command signal by measuring a holding time between pulses or a period of the pulse based on a coding mechanism of the input signal of an RFID reader. The control unit activates a power supply function of the battery by the wake-up signal. The signal detection unit has a first signal detection unit(210) and a second signal detection unit(237). If the preamble of the input signal has a specific data value, the first signal detection unit determines whether the input signal is the activation command signal, and generates an activation check signal. The second signal detection unit compares an activation mask of the input signal with a previously stored activation code in response to the activation check signal. The second signal detection unit generates the wake-up signal if the activation mask is the same with the activation code.
