摘　　要：目的实现大型离心机的自动控制。方法设计上位机和PLC构成的上下位机离心机控制系统,上位机通过以太网及OPC与PLC通讯,PLC采用Device Net总线与数字直流调速器通讯。开发基于Delphi编程语言的上位机控制软件和PLC程序。结果软硬件实现了预定功能,系统实现了大型离心机自动运行。结论该控制系统性能佳,可靠性高,操作方便。Objective To automatically control the large centrifuge. Methods A centrifuge control system of upper and lower computer was designed composed of the upper computer and the PLC. The upper computer communicated with the PLC by Enternet and OPC, and the PLC communicated with a digital DC drive by Device Net.The PLC program and the control software of the host computer were developed based on Delphi. Results Intended functions of the hardware and software were achieved, the system automatically controlled the large centrifuge.Conclusion The centrifuge control system had good performances and high reliability, and was simply to handle.
