摘　　要：以石油化工芳烃类产品生产的苯精制生产工艺流程为背景,设计一套苯精制三塔精馏生产流程实训装置PLC控制系统。讨论了基于西门子S7-300PLC控制系统的硬件组成、控制方案、硬件组态、通讯组态、PLC程序设计、监控界面设计等,最后系统经调试和PID参数整定后投入运行。设计的控制系统已广泛用于各石化企业、院校的操作技能培训与技能考核。Aimed at petrochemical aromatic products tor benzene reiining production process, a programmable logic controller（PLC） control system for the benzene refining process training device with three-tower rectification is designed. This paper considers a Sie- mens S7 300 PLC control system including hardware, control strategy, programming, MCGS configuration database, connection and monitoring interface. The system is put into operation after debug and PID parameters adjustment. The training device of PLC control system with the control strategy is widely used in petrochemical enterprises and institutions for training and assessment of skills.
