| Abstract: | To meet the demand of improving the readering and writing effciency of reader, a kind of reader plan radio frequency identification （RFID） was proposed. The hardware structure of RFID interrogator was disussed. Finally, this paper highlights the software design flow of the RFID interrogator and the realization of anticollision algorithm. The reader was suitable for uhra-high frequency band. Compared with other kind of reader which adopted traditional random anti_collision algorithm, this reader can smoothly read tags under more than one tags＇cirumstance, and anti_collision performance has a certain improvement. |
