摘　　要：为了实现超滤系统复杂的运行逻辑,提出采用S7-300 PLC来实现超滤系统的自动控制。介绍了超滤系统的工艺流程和工艺控制要求,对控制系统的硬件和软件进行了详细设计,给出了部分PLC控制程序,最终实现了单组超滤装置自动运行的逻辑控制和多组超滤装置并联自动运行的排队冲洗控制。应用结果表明,该控制系统很大程序提高了超滤系统运行的自动化程度,降低了工人的劳动强度,且运行可靠稳定,为超滤系统的控制提供了一种新的思路。In order to realize the complex operation logic of the ultrafiltration system, the automatic control of ultrafiltration system using PLC S7-300 is proposed. The process flow and process control requirements of ultrafiltration system are introduced. The hardware and software of the control system are designed in detail. The part of the PLC control program is given, and the logic control of the automatic operation of the single group ultrafiltration device is realized. The application results show that the control system greatly improves the automation level of the operation of the ultrafiltration system, reduces the labor intensity of workers, and runs reliably and stably, and provides a new way for the control of the ultrafiltration system.
