Abstract: A useful tag identification approach was proposed based-on electronic product code (EPC) and Auto-ID. Firstly, the manufacturing resources were classified in detail, and based on EPC Global encoding specification, the coding structure of RFID tag data was obtained  using custom fields of types and serial numbers. Secondly, according to the design information and production data of work in process (WIP), the manufacturing logic of WIP was generated. Based on that, the informations of manufacturing resources were automatically associated in group, space and time using database technology. Finally, the RFID tags and manufacturing informations of WIP were discussed to verify the feasibility and universality of the proposed models and methods.

摘要： 提出了一种基于电子产品编码（EPC）和自动身份识别（Auto-ID）的智能车间RFID标签有效识别方法。通过对智能车间中制造资源种类的详细划分，在EPC Global编码规范的基础上进一步细分类型和序列号两个自定义字段，得到了车间内部制造资源的RFID编码结构；根据在制品（WIP）的设计信息和生产数据形成工件制造逻辑，进而利用数据库技术实现制造资源信息在群属、空间、时间上的自动关联；最后对WIP的RFID标签和制造信息的自动关联进行了实验，以验证所提出的模型和方法的可行性及普遍性。
