The work aims to improve the inspection efficiency of products on the packaging production line and ensure the correctness of the inspection process. Based on the research of the RFID technology, anti-counterfeiting algorithm and anti-collision algorithm, a set of inspection system for the identification of products on the packaging production line was designed by means of RFID read-write functions to test and manage the ex-factory items delivered by the production line. On the basis of the overall hardware structure of the packaging production line, the RFID hardware processing module and the PC interactive interface were combined to inspect and test three hundred products with electronic labels on the packaging production line. The system was able to complete the test automatically in a shorter time, and the accuracy during the test was higher. The designed test system can improve the inspection efficiency of packaging production line and has higher market application value.
