摘　　要：近些年,经济发展突飞猛进,各行各业积极响应国家号召,推行绿色发展、安全生产,同时对产品的质量和实现过程提出了更高要求。尤其是石油炼化单位,以安全生产为前提,注重精细化生产、创造更高经济效益的同时,要求减少生产中带来的环境污染。这就对自动化仪表的精确度和安全等级提出了更高的要求。DCS控制系统是集控中心,对生产的稳定运行起到至关重要的作用,为优化成本控制、提高DCS控制系统可靠性、扩展I/O点、避免控制系统故障、维护正常生产,有条不紊地更换并完善DCS系统,并在此基础上引入先进控制,提升控制水平。In recent years,with the rapid economic development,all walks of life actively respond to the call of the state to promote green development,safety in production,while product quality and implementation process put forward higher requirements.In particular,petroleum refining units,on the premise of safe production,pay attention to fine production,to create higher economic benefits,at the same time,reduce production of environmental pollution.This puts forward the higher request to the precision and the safety grade of the automatic instrument.DCS control system is a centralized control center,which plays a vital role in the stable operation of production.In order to optimize cost control,improve the reliability of DCS control system,extend I/O point,avoid control system failure,maintain normal production,replace and perfect DCS system in an orderly manner,and on this basis,the introduction of advanced control to enhance the level of control.
