摘 要：
GS1是EAN/UCC的新名字,由编码体系、可自动识别的数据载体和电子数据交换标准组成的全球统一标准。本文基于GS1标准,针对"源头"追溯、标准化、动态数据共享等难题,搭建了牛肉全过程质量追溯系统的通用框架。框架中个体标识采用RFID耳标与EAN/UCC条码,RFID耳标编码采用EPCglobal标签数据标准;各流通环节的信息服务器采用三层架构:访问层、业务层、资源层,异构分布架设,以HTTP/SOAP协议提供用户访问接口;采用信息发现服务结合对象名服务,定位动态分布的信息服务器,实现动态数据共享。

摘 要：
GS1 is a new name of EAN/UCC,which is composed of encoding system,automatic identifiable data carriers and electronic data exchange standards.Due to unsolved problems related to the origin tracing of foods,standardization of RFID tags and sharing of dynamic data,it is urgent to establish a full supply chain traceability system for beef.In this study,a general framework of GS1 full supply chain traceability system for beef was established using RFID tags and EAN/UCC codes with EPCglobal tag data standards to conduct tracking from farm to fork.Each information server contained access layer,business layer and resource layer.These servers were heterogeneously distributed to provide user an accessing interface through SOAP or HTTP protocol.In order to accomplish the sharing of dynamic data,information-searching service combined with target-name service was used to locate dynamically distributed information servers.
