基于条码-RFID关联的蔬菜流通过程追溯精确度提高方法

【目的】解决不同包装单元的聚合与拆分导致的流通过程追溯精确度不高的问题，为实现蔬菜全程质量安全追溯体系的建立奠定基础。【方法】采用条码和无线射频识别（RFID）分别对不同包装单元进行标识，开发便携式流通信息采集系统和升级蔬菜企业信息管理系统。【结果】实现了RFID TID与小包装产品追溯号之间的关联及流通过程信息采集，从而提高流通过程追溯精度；将本方案应用于山东省某蔬菜生产企业中，通过应用测试结果表明，本方案的关键环节之一条码读取率在距离为20 cm以内，其读取率高于95%；另一关键环节关联正确率达到100%。【结论】该方法可进行实际应用以实现到单品或单批次到流通过程的追溯。

A Solution for Improving Vegetable Circulation Traceability Precision Based on Barcode-RFID Correspondence

【Objective】 The aim of the study is to improve the low traceability precision in vegetable circulation process affected by aggregation and splitting in different package units. The improvement will pave a way to establish quality safety traceability system from farm to table. 【Method】 In the paper, barcode and RFID were adopted for identifying different package units. A portable circulation information acquisition system was developed and the vegetable enterprise management information system was updated.【Result】The relationship of RFID Tag ID and traceability codes on small packages was implemented and the correspondence of circulation process information was collected. Consequently, traceability precision in circulation process was improved on the relationship and correspondence. The solution was applied in the traceability management of a vegetable enterprise in Shandong province. The application test results showed that the traceability barcode reading rate in the range of less than 20 cm as an important stage in the solution was above 95%, and the correct correspondence rate as the other stage was 100%. 【Conclusion】 Therefore, the solution can be applied in order to implement single product or single batch traceability in circulation process.
