目的 针对现有商品条码与RFID标签数据转换方法编码僵化、信息承载不足、可读性差的问题,研究一种适用于包装领域的柔性转换方法,提升包装标识的数据完整性、人机交互友好性及标签芯片的内存适配效率。方法 提出一种多模式标签数据转换方法。通过AIDC位控制附加信息嵌入,设计SGTIN+与DSGTIN+双编码架构。保留GTIN原始格式以保持可读性;设计6类系列号差异化编码方案以适应不同数据类型。开发B/S架构原型系统,选取典型包装数据,与SGTIN-96/198方法进行编码与解码对比实验,从信息完整性、存储效率和人工可读性等方面进行验证。结果 经对比验证,该方法可成功编码传统方法无法处理的时间信息;编码结果中GTIN字段保持人工可直接识读,且整体编码长度较SGTIN-198方案显著缩短。结论 该方法有效解决了传统转换方法的扩展性、适应性与可读性局限,为包装标识的数字化升级提供了可行方案。
Abstract
To address the limitations of rigid encoding, insufficient information capacity, and poor readability in current barcode-to-RFID data conversion methods, the work aims to develop a flexible conversion method tailored for packaging applications, to improve the data integrity of packaging identification, the friendliness of human-computer interaction, and the memory adaptation efficiency of tag chips. A multimodal label data conversion method was introduced, featuring a dual-encoding architecture (SGTIN+ and DSGTIN+) with an AIDC control bit for embedding GS1-compliant additional data while preserving the original GTIN format to enhance readability. Six differentiated encoding schemes were also designed to accommodate varied serial number data types. A B/S-based prototype system was implemented and evaluated with representative packaging data. Comparative encoding and decoding experiments against conventional SGTIN-96/198 methods demonstrated that the proposed method successfully encoded temporal information that could not be processed by conventional methods. The GTIN field in the encoded result remained human-readable directly, and the overall code length was significantly shorter than that of the SGTIN-198 scheme. The method effectively overcomes the scalability, adaptability, and readability constraints of traditional conversion techniques, offering a practical pathway toward digital advancement in packaging labeling.
