Abstract

Aiming at the tag collision problem in the actual application of the radio frequency identification system (RFID), this paper proposes an active radio frequency identification method and system supporting parallel anti-collision. The active tags work in parallel and the conversion time of adjacent active tags is partially overlapped. Significantly parallel anti-collision system shorten the identification time of the entire system, while ensuring that only one active tag sends data to the reader at the same time, which can effectively improve the anti-collision performance of the radio frequency identification system. It makes the averaged delay 5.83% of that of the traditional dual-channel system. The more tags, the more obvious the superiority of the parallel anti-collision system. The system has good engineering practical value and can be used in applications that have strict requirements on reading speed.
