摘要
自动化仪表是石化工业生产过程中,对工艺参数进行检测、显示、记录或者控制的基础。现场仪表、分析仪表、控制方案及依存的DCS(Distributed Control System)、SIS(Safety Instrument System),管控一体化依存的ERP及相应的计算机系统等,构成了石化企业的自动化解决方案。通过对石化自动化仪表及控制系统的阐述,希望能为同行提供一定的参考和借鉴作用。
Automation instrumentation was the basis of petrochemical industrial production process of parameters detection,display,record and control. Field instrumentation,analytical instrumentation,control solutions and dependent DCS（ Distributed Control System）,SIS（ Safety Instrument System）,ERP management and control integration and interdependence of the corresponding computer systems formed the petrochemical enterprise automation solutions. By describing the petrochemical instrumentation and automation control system,some reference and reference for the peer were provided.
