In order to achieve the slaughterhouse’s network management and informationization, ensure the safety of the pork production, the text using modern network technology and Radio Frequency (RF) communications technology, with RFID tags and one dimensional barcode as a carrier of the pig identification information, combined with the SQL Server2008, we construct pig slaughtering traceability system. Using STC11F32XE and RC522, a RFID reader is developed, that communicate based on serial port, and the RFID PC software and the pig slaughter software system are designed based on Visual Studio 2008. The test results show that the system has a good stability and friendly human-machine interaction, extension with high economic and practical value.
