基于射频识别中间件的粮食质量安全追溯系统

为建立快速、全面、精确的粮食质量安全追溯信息系统，研究了射频识别（RFID）中间件技术应用在粮食质量追溯中的业务流程及使用方式，结合江苏省粮食流通特点完成了基于射频识别中间件技术的粮食供应链的系统流程分析，进而确定了符合粮食质量安全中间件的软硬件配置。在此基础上采用结构化设计方法（SM）进行粮食质量安全追溯RFID中间件应用体系的系统架构。最后分别应用VC++方法和AutoRunner工具对系统进行集成和测试。单标签和动态应用测试结果表明：系统识别准确率、识读工作周期和系统连续正常运行时间分别达到95.3%、8.6 s和1 000 h。该系统具有应用于粮食质量安全追溯的前景。

Traceability system of grain quality safety based on radio frequency identification middleware

For constructing traceability system of grain quality safety with fast, comprehensive and precise characteristics, the operation flow and the application mode on grain quality traceability had been analyzed. The analysis of the system flow was carried out based on the RFID (radio frequency identification) middleware in the grain supply chain considering the grain circulation practice in Jiangsu Province. In the mean while, configuration of the hardware and software was studied. Based on the research results, the system architecture of grain quality traceability with RFID middleware technology was proposed by structured design method. Then, the system integration and test had been taken with VC++ language and AutoRunner testing tool. Practical dynamic tests with single tag achieved the system identify accuracy, identify working cycle (the cycle from reading the label to releasing information to the Internet) and MTBF (mean time between failure) with 95.3%, 8.6 s and 1 000 h, respectively. The system has the potential application for tracing grain quality and safety.
