DCS在石油化工中的应用

The Application of DCS in Petrochemical Industry

DCS主要由控制站、操作站和工程师站、数据通信及网络等三部分构成,它具有模拟量的数据采集和控制,开关量的顺序控制,开关量、模拟量结合进行控制,即混合控制功能,除此之外还有人机界面友好、安全可靠、易于安装、容易使用、便于维护、便于扩展和升级换代等特点。该系统在石油化工等行业中应用广泛。

DCS mainly includes three parts as the control station, operation station, engineering station, data communications and networks. It has the data acquisition and control of analog quantity, the order control of switch quantity, the combination control of switch quantity, analog quantity, that is the mixture control function. Besides that, it has the advantages such as friendly human-machine interface, safe and reliable, easy to install and use, easy to maintain and expand and upgrade and so on. The system is widely used in fields such as petrochemical industries.
