摘　　要：农产品流通环节是实现农产品质量追溯系统的关键环节,为改进传统方式如索证、索票等在建立农产品流通追溯系统时存在的操作不足,该文以农产品可信流通控制技术为基础,采用"硬控制"的设计思路,以自主研发的多功能嵌入式农产品流通专用设备为控制工具,以上位机农产品流通追溯系统为业务支撑,建立了基于Linux嵌入式技术的农产品流通阶段质量追溯系统。多功能流通专用设备集RFID(radio frequency identification)身份识别、二维条码打印、无线数据上传于一体,实现了产品准入、市场抽检和市场追溯,并通过网络、POS(point of sales)机实现了公众查询追溯服务,建立了可操作的农产品流通追溯系统模型,具有良好的推广应用前景。Circulation of agricultural products is the key stage of the whole product quality traceability system. Traditional methods such as supervision credentials,supervision ticket and so on being used to establish agricultural product traceability system were greatly difficult in operation.In this paper,the method of＂hardware control＂was used to construct the agricultural product circulation quality traceability system based on the Linux embedded technology. This system was designed based on the credibility of the control flow of agricultural technology,by using the multi-function embedded special equipment as the inspection tool,and the product circulation traceability system for business support.The multi-function circulation special purpose equipment integrated the function of radio frequency identification（RFID）status recognition,the two-dimensional bar code printing,wireless data uploading,and the system provided product admittance,market spot-check and product traceability service through the touching screen and network.The research established the operable model of agricultural product circulation traceability system and had a good prospect of application and extension.
