摘要
根据烟叶复烤生产工艺的特点及控制要求,分析并设计了烟叶水分、温度、流量和联锁控制方案;构建了基于Ethernet+PLC+Interbus的分布式控制系统。根据控制方案及其控制方式,采用功能图(FBD)编写了PLC控制程序;并利用Citect组态实时监控程序,满足了复烤生产控制要求。
According to the features and control requirements of the redry technology, the control strategy of flow, moisture, temperature for tobacco leaf are outlined. A distributed control system of Ethemet ＋ PLC ＋ Interbus is proposed. The control and monitor progams are designed with FBD and Citect.
