摘要： An RFID reader/writer including a reader/writer body, antennas and an antenna switching unit is provided. The reader/writer body distributes to each of its own ports a length of sustained time for transmitting a signal. One end of the antenna switching unit is connected to one port of the reader/writer body, while the other end is connected to two antennas. The antenna switching unit acquires a length of sustained time for the signal transmission distributed to the port by the reader/writer body, configures the time-length for the signal transmission and the sequence thereof of the two antennas according to the length of sustained time for the signal transmission, obtains a configuration result for signal transmission, and performs a switching control on the signal transmission of the two antennas according to the signal transmission configuration result. Further, an implementation method for the antenna switching of the RFID reader/writer is described.

摘要： A method for conducting a passive label query in a radio frequency identification system, wherein a query process conducted by a reader for a group of passive labels comprises a first query and a subsequent query. The link frequency used by a reverse link from the passive label to the reader in the subsequent query is smaller than that the link frequency used by the reverse link in the first query. The method improves the reverse link performance of a passive label radio frequency identification system, and increased the reading success rate of the passive label. A reader is also provided to implement the method.

摘要： An apparatus, system and communication method, which is particularly suited for a radio frequency identification system (RFID), wherein a reflection-transmission apparatus is disposed in a radio system and, during a communication process, the reflection and transmission features of reflection-transmission apparatus presented at the radio frequency are changed to introduce a multi-path signal component which changes with time. Consequently, during the communication process, a receiving apparatus receives and combines the multi-path signal component of communication signals and the radio system performs communication by utilizing time diversity effects. The apparatus, system and method provide effective and continued reduction of communication blind spots in the RFID system, thereby improving the overall success rate for the RFID system to read tags and accomplishing a better balance with the overall reading time.

摘要： A method in a Radio Frequency Identification (RFID) system including at least one reader/writer and a group of tags each attached to a workpiece. The method includes reading a plurality of tags from the group of tags, capturing received signal strength indication envelopes of tags, and storing the received signal strength indication envelope one tag as a template. A correlation match is performed for the received signal strength indication envelope of the tags and the template to obtain a time interval between the received signal strength indication envelope of each of the tags and the template when the correlation is at a maximum value. Using the present invention, the at least one reader/writer can report each tag that is directly in front of an antenna, even if multiple tags exist in the complicated industrial environment, ensuring First Come First-Read (FCFR) and improving the reliability of an ultra high frequency RFID system.
