Profinet-based Mobile RFID Control System for Flavoring and Casing in Primary Processing Line

In order to avoid the flavoring or casing being added to wrong tobacco due to the lack of real-time material information transferring in primary processing line, a Profinet-based mobile Radio Frequency Identification(RFID) control system for flavoring and casing was developed. Wherein an RFID reader was linked to a distributed I/O system through a gateway module and communicated with a master PLC via Profinet. The RFID reader read the information labelled on the flavoring/casing tanks and vehicles, and automatically transferred it to the I/O system and PLC. The realization of automatic read, recognition and identification of vehicle number, tank number, the flavor/casing in tank and the tobacco to be treated ensured the integrity and accuracy of production information and quality information in the process of flavoring and casing, and free the flavor or casing from being added to wrong tobacco.
