Introduction

GB/T 41734 mainly involves the consistency of radio frequency identification tags and radio frequency identification readers. Currently, radio frequency identification tags used for animal identification

The main type of tag is injection type RFID tag, mainly including electronic ear tag RFID tag, electronic rumen pill RFID tag, leg ring

RFID tags. GB/T 20563 specifies the code structure for animal radio frequency identification, and GB/T 22334 specifies the technical code for animal radio frequency identification.

Technical guidelines, GB/T 41734 mainly solves the consistency between radio frequency identification tags, radio frequency identification readers and GB/T 20563 and GB/T 22334

Performance evaluation, performance evaluation and other issues.

Radio Frequency Identification of Animals Part 7.

GB/T 22334 Synchronization between identification systems

1 Scope

GB/T 41734.7-2023 is the part of the animal radio frequency identification series that governs what happens when two or more readers work close enough together to hear one another. Half-duplex tags are charged by an activation field and answer on frequencies that sit near it, so a reader listening for a faint tag response while a neighbour is still transmitting hears the neighbour instead — animals passing a race, a parlour or a weighing crate go unrecorded, or are recorded as the animal ahead of them. The remedy set out here is a shared synchronization line. Clause 5 defines the protocol that lets readers agree whose turn it is to energise and whose turn it is to listen, clause 6 shows how a synchronized system is put together, clause 7 fixes the electrical characteristics of the bus that carries the timing signal, clause 8 the synchronization method itself, including mobile reader synchronization, and clause 9 the hardware of the synchronization circuit. Annex A carries the normative timing diagram. Terms and abbreviations are taken from Part 1, and the tags concerned are those of GB/T 20563 and GB/T 22334. Written for reader and ear tag manufacturers, livestock traceability integrators, farms running fixed reading points, and conformance laboratories.

This document establishes the synchronization of radio frequency identification readers when reading radio frequency identification tags that comply with GB/T 20563 and GB/T 22334

Rules and Procedures.

This document applies to radio frequency identification readers used in animal farming.

5.1 General

In the identification system conforming to GB/T 20563 and GB/T 22334, two or more radio frequency identification readers have

Synchronization is necessary. Half-duplex RFID tags use 2 frequencies to transmit data, one of which is the same as the activation signal. 2 or more

When the upper RFID reader works independently, that is, it works asynchronously, while other RFID readers receive HDX RFID tag signals

can generate an activation signal. Therefore, RFID readers may interfere with each other unless the activation signal is turned on (read FDX RFID tags

tag) and off (reading HDX RFID tags) periods are synchronized. Synchronized RFID readers coordinate sending activation signals, receiving

HDX radio frequency identification tag signals, and will not interfere with each other.
