Abstract

The invention provides an RFID (Radio Frequency Identification) reader with multiple antennae working simultaneously, and a radio frequency data signal identification method of the same. The RFID reader comprises an anti-collision unit, more than two radio frequency units and more than two antennae, wherein the radio frequency units are respectively connected with the anti-collision unit, and each antenna is connected with one radio frequency unit. The RFID reader can be used for realizing simultaneous working of multiple antennae of RFID, and solving the problem that the existing multi-antenna RFID system is prone to identification omission when only one antenna can work at the same time.

Description

technical field [0001] The invention relates to the technical field of RFID communication, in particular to an RFID reader-writer with multiple antennas working simultaneously and a method for identifying radio frequency data signals. Background technique [0002] At present, multi-antenna RFID readers at home and abroad, such as figure 1 As shown, it includes an anti-collision unit, a radio frequency unit, a radio frequency switch unit and multiple antennas, wherein the anti-collision unit also includes a radio frequency switch unit, which is used to control the radio frequency switch unit, so that the radio frequency switch can switch the antenna, An antenna can radiate multiple channels. In order to avoid the interference of multiple antennas radiating signals at the same time, the existing multi-antenna RFID reader adopts a multi-antenna polling working mode, that is, only one antenna can work at the same time. This method is used to detect electronic tags attached to ...
