| 目的 确保物品包装上的超高频射频识别(Radio Frequency Identification, RFID)标签一致性关键指标符合相关标准，解决现有文献对一致性关键指标阐述不全面的问题，基于ISO/IEC 18000-63和ISO/IEC 18047-63对一致性关键指标的测试方法展开研究。方法 在对现有一致性测试方法进行研究阐述的基础上，改进了状态跳转和截断响应的测试方法，提升了测试准确性;设计了一种时隙计数器测试方法，该方法通过改变Q值和重复发送QueryRep命令，验证时隙计数器在非0到0的变化过程中，标签有且仅有一次响应，从而避免出现多个标签同时应答的现象。结果 应用改进及新设计的测试方法对指定标签进行测试，结果符合标准。结论 较为全面地实现了对RFID标签的客观验证和有效评估，对提升RFID标签在实际应用中的可靠性具有重要意义。 |

| Abstract: |
| To ensure that the key indicators for conformance of the UHF RFID tags on the packaging of items comply with relevant standards and address the issue of incomplete description of key indicators in existing literature, the work aims to study the testing methods of the key indicators for conformance based on ISO/IEC 18000-63 and ISO/IEC 18047-63. Based on the research and explanation of existing conformance testing methods, the testing methods for state transition and truncated response were improved, enhancing the accuracy of testing. A testing method for slot counter was designed, which verified that the slot counter responded only once during the non-zero to zero change process by changing the Q value and repeatedly sending the QueryRep command, thus avoiding the phenomenon of multiple tags responding simultaneously. By the improved testing method, the designated tags were tested and the test results met the standards. This study achieves more comprehensive objective verification and effective evaluation of RFID tags, which is of great significance for improving the reliability of RFID tags in practical applications. |
