摘要:
利用RFID标签标识茶叶供应链全过程信息流以加强茶叶物流关键信息的追踪与追溯。基于.NET进行系统总体设计,由业务层、中间件层、数据层和应用层构成系统架构;设计符合茶叶物流特征的电子标签EPC编码,基于ASP+SQL Server 2008构建系统数据库;基于MFC编程进行时隙ALOHA算法与二进制搜索算法仿真。结果表明,中间件的设计有效解决硬件不兼容、信息冗余等问题,提高追溯系统的响应效率;时隙ALOHA算法总体上具有更高的识别效率,更适合应用于本系统。

Abstract:
To enhance the efficiency of tracking and tracing key information of tea logistics, RFID tags were applied to identifying flow information in the tea supply chain.The system was designed based on .NET and its structure was composed of four layers, business layer, middleware layer, data layer and application layer. The electronic label EPC encoding was designed according to the characteristics of tea logistics and a database was built based on Sever ASP+SQL 2008. The simulations of Slotted-ALOHA protocol and Binary-tree search protocol were carried out based on MFC programming. The results proved that: the design of middleware can not only effectively solve such problems as hardware incompatibility and information redundancy, but also improve the response efficiency of the tracing system. Slotted-ALOHA protocol has a high recognition efficiency, which is more suitable for the system.
Key words:  RFID(radio frequency identification devices)  database  middleware  anti-collision algorithm
