为解决传统管道料液输送方式存在的物料信息不能自动传递和对比而发生料液混料、烟丝混牌和错牌质量事故的问题，采用RFID（Radio Frequency Identification）加PLC（Programmable Logic Controller）的控制方式，通过在料罐上加装电子标签，用RFID读写器读写电子标签中的物料信息，RFID 读写器通过网关模块接入现场分布式I/O ，通过Profinet网络与主控PLC通信，实现了移动料车车号、料罐罐号、罐中料液和待处理烟丝牌号等信息的确认、识别和无接触读取的自动化，保证了加香加料过程的生产信息与质量信息的完整性与正确性，较好地解决了传统加香加料过程中混料、混牌和错牌等问题。%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.
