GB/T 22334-2008Radio-frequency identification of animals -- Technical concept (English PDF)

Foreword

This revised standard adopts ISO 11785:1996 "Guidelines for Animal RFID technology" (in English).

This standard is based on ISO 11785:1996 redrafted. The standard lists the reg number and ISO 11785 in Appendix A. Chapter 1996 Article number of the control list.

Taking into account China's national conditions, in the use of ISO 11785:1996, the following modifications of the standard, technical differences have been incorporated into the text.

a) increasing the administrative department of radio frequency identification devices emitting magnetic field strength requirements (4.1.1, 4.1.2 of this standard);

b) increase the administrative department of radio frequency identification equipment spurious emission limit requirements (4.1.1, 4.1.2 of this standard);

c) Appendix B (ISO 11785:1996 Annex A) to an information appendix.

In order to facilitate the use of various user-related equipment manufacturers, system integrators and users, etc., the editorial changes made the following standards.

a) Remove the ISO 11785:1996 Foreword and Introduction;

b) Delete the ISO 11785:1996 Consistency section (ISO 11785. Chapter 21 996);

c) the terms of the order have been adjusted;

d) Remove the ISO 11785:1996 English abbreviation chapter (ISO 11785. Chapter 51 996);

e) on the "technical requirements" in accordance with RFID readers, RFID tags, content and transmission format, full-duplex and half-duplex system parameters Sequence number were rearranged.

This standard Annex A, Annex B, Annex C is informative annex, Annex D is normative appendix.

The standard proposed by the Article Numbering Center of China.

This standard by the National Standardization Technical Committee of agricultural machinery.

This standard was drafted. Article Numbering Center of China.

1 Scope

This standard specifies the radio frequency animal identification between RFID readers and RFID tags technical information required for bidirectional communication.

This standard applies to animal messaging RFID readers and RFID tags between the radio frequency identification process.
