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： A reader and method for adjusting the transmission time of a continuous wave (CW), wherein the method comprises setting an initial value for a response waiting time, sending the CW to a tag after sending a command to the tag and waiting for a response from the tag, judging whether the response from the tag is received within the response waiting time. If the response from the tag is received within the response waiting time, then sending of the CW is stopped and the response waiting time is adjusted. If the response from the tag is still not received beyond the response waiting time, then sending of the CW is stopped. The time for the reader to wait for a response from the tag is far less than 20 ms. Consequently, a command failure can be found early, so as to improve the processing efficiency of an RFID system.
