基于Profibus的逆流式烘丝机控制系统的设计

The Design of Profibus-Based Control System of Count-Current Cut-Tobaco Dryer

根据卷烟企业自动控制技术的发展趋势,通过对现场总线技术的分析和研究,针对烘丝机的工艺控制要求,设计了一套以Profibus现场总线技术为基础的烘丝机分布式控制系统,文中介绍了系统的硬件结构及检测、控制功能的实现。运行结果表明:现场总线技术是实现分组加工需要的烘丝机自动控制的一种可行的解决方案。

According to the development trend of cigarette-factories＇ automatic control technology, by analyzing and investgating the technique of fieldbus, aiming for the requirement of cut-tobacco dryer＇s process control, profibus-based distributed control system of cut-tobacco dryer is designed. The paper introduces system＇s hardware configuration and realization of function of measuring and control. Experiments shows that the technique of fieldbus is the workable solution of automatic control in cut-tobacco dryer that subgroup making needs.
