Abstract


With the development of society and the improvement of living standards, people are more and more high quality requirements of life are increasingly concerned about the security issues of life in a variety of consumer goods, the countries of the world have increased to ensure consumer safety, building security system efforts effective means to introduce a product traceability system as the quality and safety management. Now product traceability range has also been retrospectively from the past use of the product materials, development to modern traceability of the production process and product shipping logistics situation. Traceability information system in animal products, the production and processing is an important part, it connects the two parts of the supply chain of raw materials and finished products distribution chain, traceability system uniquely identifies the track, and the whole process has played an important role in the product. This article, based on the actual situation of China's agricultural industry, the production and sales of pork products, for example, bar code label from the the pig breeding stage wearing ear label to the sale of part of the pork products, pig identification ear tag only in the slaughter, segmentation, packaging, etc. product of individual identification technology in the production process in the information chain, identification, recording, management of raw materials, semi-finished products, finished products, thus establishing traceability system sales from breeding to full information. In this paper, sales of pork products from pigs individuals to market information processing traceability chain consistency and coherence of the system design and implementation, the main research content and results are as follows: ① the production of animal products traceability system as a whole analysis and design, petri net theory and pork slaughtering and processing process, we proposed the formation of an information flow link identification information and the product of individual information processing model based on the petri nets pork production chain processes, information systems provide a basis for analysis and optimization as well as the development of application software systems. ② unified identity EAN · UCC system is the product of individual and pork product traceability, for example based on its design characteristics of the product barcode automatic identification technology, integrated RFID (radio frequency identification) and barcode technology to automatically identify individual product information data automatic acquisition and transmission of information on the basis of individual product tracking and identification of the \The ③ proposed process control in the production process adapted to animal products production information traceability system realization method, through the analysis of pork production and processing, to establish the chain of traceability information, and analysis of the system in production and processing chain logo with key technology for data management and information acquisition control unit, through tracing system database, set up to meet traceability information framework for the information required in the system. Thesis of beasts production information can be traced back pork safety information traceability system development and application \can be traced back to the system's data and traceability requirements.
