Embodiment 1

[0039] see figure 1 with figure 2 shown.

[0040] The invention provides a control method for identifying an electronic tag by an RFID reader-writer, the method comprising the following steps:

[0041] S1: Transmit a single carrier to the electronic tag, so that the electronic tag is powered on.

[0042] S2: Send the first inventory command, and configure the encoding mode of the echo of the electronic tag as FM0 encoding.

[0043] S3: Receive the echo of the FM0 code sent by the electronic tag, and identify the inventory mark in the echo.

[0044] If S31: identify the inventory identification of the electronic tag whose echo is FM0 code; set the inventory identification of the identified electronic tag to the recognized state, and the inventory identification of the recognized state will no longer repeatedly respond to the first inventory instruction; continue to step S4 ;

[0045] It should be noted that, according to EPC C1G2 and GB / T 29768-2013 air interface specific...

Embodiment 2

[0058] see image 3 shown, see again figure 2 shown.

[0059] The invention provides a control device for an RFID reader-writer to identify an electronic tag, and the control device includes a receiving module, an identification module, a sending module and a control module;

[0060] The control module controls the sending module to send the first inventory instruction, and configures the encoding mode of the echo of the electronic tag as FMO encoding; the receiving module is used to receive the echo sent by the electronic tag in the encoding mode of FMO; The identification module is used to identify the inventory identification in the echo of FM0 code, and set the identified inventory identification to the recognized state and no longer repeatedly respond to the first inventory instruction. It can be understood that when the received encoding method is The inventory marks in the echo of FM0 are all identified as identified states, that is, after the identification module i...

Abstract

The invention relates to a control method for electronic tag identification for an RFID (radio frequency identification) reader. The method comprises the following steps: a first inventory instruction is sent, a coding mode of echoes of electronic tags is configured to be FM0 (bi-phase space) coding; the FM0 coded echoes sent by the electronic tags are received, inventory tags in the echoes are identified, and a trigger signal is generated after the inventory tags of all the electronic tags with FM0 coded echoes are identified; a second inventory instruction is sent according to the trigger signal, and coding of the echoes of the electronic tags is configured to be Miller coding; the Miller coded echoes sent by the electronic tags are received, inventory tags in the echoes are identified, and the inventory tags of all the electronic tags with the Miller coded echoes are identified. According to embodiments of the invention, requirements for the tag identification success rate and the tag identification speed are both taken into consideration, the RFID reader can adapt to different radio work environments automatically, and the electronic tag identification efficiency of the RFID reader is improved effectively.

Description

technical field [0001] The invention relates to the technical field of RFID wireless communication, in particular to a method and device for controlling an RFID reader-writer to identify an electronic tag. Background technique [0002] In recent years, radio frequency identification (English: Radio Frequency Identification, abbreviation: RFID) technology, as an automatic identification technology, has developed rapidly at home and abroad. Radio frequency identification technology has the advantages of fast reading speed and wide range of functions, and is widely used in various fields. field. [0003] RFID consists of three parts: electronic tags, readers and application systems, in which the readers send data to the electronic tags, while the electronic tags send the data to Sent to the reader, the reader technology in the prior art uses the FM0 code with higher coding efficiency to obtain higher tag identification efficiency in the tag echo in the environment with less ra...
