摘  要：
针对监管技术落后、产品售价低等因素造成的农资流通体系尤其是信息链不健全问题,该文利用RFID(radio frequency identification)和网屏或二维码相结合的混合编码模式,提出了一种农资信息溯源服务系统并展示了其应用。该系统由感知层、数据层和服务层组成,面向多种农资信息溯源服务对象。重点讨论了电子标签的选择与编码方法、防伪措施以及质量溯源服务中信息追溯过程和追溯码的回溯算法。通过农资信息溯源平台的示范应用表明,该方案具有节约标签使用成本,降低服务器存储空间开销的优点。由于系统集成了农资供应链商务平台等功能,可在保护农民利益、净化农资市场及树立商家品牌形象方面发挥重要作用。

摘  要：
Because of backward technology of supervision and low price of products,the circulation system of Agricultural Products especially its information chain is still imperfect.A traceability service system for products was developed using hybrid encoding method based on electric labels of RFID and NetScreen code or Two-dimensional code.The system oriented to serve several kinds of users and includes sensing layer,data layer and service layer.The encoding methods,security measures and the processes of quality traceability were introduced,and a backtracking algorithm for computing of three layers tracing-code was also studied in the paper.The demonstration of the system shows that the system is valuable in reducing usage cost of labels and saving storage space of server as well.Moreover,the system integrates the functions of business supply chain etc.The system plays an important role in purifying the products market,protecting farmers'benefits as well as establishing a good brand image of the enterprise.
