《GB/T 41734.2-2022动物射频识别 第2部分：射频识别读写器与GB/T 20563和GB/T 22334的一致性评估》由TC201（全国农业机械标准化技术委员会）归口，TC201SC6（全国农业机械标准化技术委员会农业电子分会）执行，主管部门为中国机械工业联合会。
Introduction
Core requirements of the standard and technical improvements
RFID readers must meet three key improvements: adopt China's self-developed code mechanism (replacing ISO11784/HH-), strengthen tag compatibility detection capabilities (HDX/FDX-B dual-mode), and support enhanced tag identification (RUDI bit verification).
Comparison of consistency assessment frameworks
| Test dimensions | International standard ISO246312 | Chinese standard GB/T41734.2 |
|---|---|---|
| Applicable standards | ISO11784/11785 | GB/T20563/22334 |
| Tag compatibility requirements | 17 types of protocol tags | 20 types of compatible tags |
| Special function items | Single enhanced tag recognition | Dual enhanced mode recognition |
Key Technical Indicators of the Test Procedure
Activation Field Timing Detection Specifications
- Startup Response: The startup response must be completed within 1ms when the field strength reaches 80%
- FDX-B mode compatibility: Dynamic adjustment of activation duration (50-100ms)
- Error Suppression: Automatic noise reduction threshold for receiving bit errors ≤-20dB
Key Points for Wireless Synchronization Test Verification
- Field Strength Test: Strict 100dBμV/m@1m Test Base Point
- Phase Synchronization: Delay Tolerance ±0.5ms
- Interference Test: Noise Injection Level Control ±3dB
Recommendations for Standard Implementation and Application
Manufacturers are advised to pay attention to the following when using the new electronic ear tag reading and writing equipment:
Links Implementation points Reference clauses Product research and development Integrated spectrum self-calibration module 7.4.2 Test verification Complete the three-level pressure environment test 7.8 Registration application Prepare the electromagnetic compatibility test report AppendixA
