A study on pig slaughter traceability solution based on RFID

Abstract

Due to an assembly line production and poor environment conditions in pig slaughterhouses, collection of slaughter tracing information is not a simple thing. Based on the UHF radio frequency identification (RFID) technologies, this study designed a RFID tag for carcass, a RS232-PS2 data conversion line and some data norms such as the RFID carcass tag and partition meat label norm, and developed online reading and writing system for RFID tags, accomplished RFID identification for carcass and automatic identification on the slaughter line. Through identifying ear tags at the pig heading process, fixing RFID carcass tags at the half-carcass process, printing partition labels at pork exclusive stores, the study were able not only to collect, transmit and deal traceability information for pig slaughter in the key processes of the whole pig slaughter line, but also print a set of commercial cutting meat tags of 1D bar code based RFID carcass tag in the sales store. This study has been applied for demonstration in Tianjin and explored any possibility for application of RFID technology in pork quality traceability system from both technology and application links. © 2011 IFIP International Federation for Information Processing.
