Abstract: 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.
