摘要:: 根据企业要求,以可编程控制器(PLC)为主控设备,以触摸屏为人机接口,两者之间进行通讯,实现精炼油过程中主要工艺参数的监控。通过控制算法的设计使系统能自动完成所要求的各项功能,确保成品出油的各项参数均达到预定要求。该设计经实用验证达到了企业的目标要求。

Abstract:: The paper puts forward a design scheme for oil refining control system. According to the requirements of the enterprise, programmable logic controller (PLC) is designed to be the master control device in the system. Touch screen is made to be the man-machine interface so that the operators can monitor the main parameter in the refining process. By using control algorithm, the system is able to automatically complete the required tasks, ensure that the pa— rameters of finished product-oil reach predetermined requirements. The design is proved to able to live up with the re— quirements set by enterprises.
