Tracing method, tracing device and tracing system

Abstract

The invention provides a tracing method, a tracing device and a tracing system. The tracing method comprises the following steps: acquiring a pig image of a slaughtered pig; determining meat grade information of different parts of the slaughtered pig according to the pig image; and generating a sub-tracing code associated with the part according to the meat grade information. According to the tracing method, the tracing device and the tracing system, when the pigs are slaughtered, the meat grade information of each part of the pigs is determined through the images of the pigs, and the meat grade of each part does not need to be manually determined, so that manpower is saved, and the influence of human experience is avoided, and the determined meat grade is relatively accurate. Besides, thesub-tracing codes are associated with the meat grade information, so that the user of the consumer side can quickly trace the meat grade information of the corresponding part through the sub-tracingcodes, and the tracing method is transparent and direct, so that people can eat the meat more safely.

Description

technical field [0001] This application relates to the technical field of information traceability, in particular to a traceability method, a traceability device and a traceability system. Background technique [0002] The purpose of pork grading is to determine the meat grade of pork fairly, so that both producers and sellers have common standards to follow, and prevent disputes under the principle of fair and reasonable transactions. Pork grading has become an important factor affecting the economic benefits of pig breeding and slaughtering and processing enterprises. However, when current butchers sell pork, they usually roughly judge the meat grade of the pig's pork according to their own experience, which not only wastes manpower, but also the butcher's determination of the meat grade is often not accurate enough. In addition, since the meat grade of pork is only judged by the butcher, the user cannot trace the meat grade information of each part of the pig. Contents...
