OPC技术在天然气行业控制系统中的应用

Application of OPC Technology in Natural Gas Controlling System

当前工业生产中广泛采用了PCS(Process Control System)系统,天然气行业也不例外。控制系统需要将现场仪表采集的信号传输给HIS(Human Interface System)控制站进行监控。如何使得控制系统与HIS站之间稳定、高效的传输数据,是控制系统设计中的一个关键问题。同时,如何将过程数据传输给第三方设备,以便于生产系统信息化的建设也是目前生产企业需要解决的问题之一。文章讨论的OPC技术即是基于此类问题上的解决方法之一。

At present PCS（Process Control System）has been widely used in industry production ,no exception for natural gas industry. It needs to monitor signals transferring from field instruments to HIS（Human Interface System）control stations. It is important to make signals transferred efficiently between control system and HIS, and how to transfer signals to the third party device is also a problem to be done in the process of informatization for the manufacturing enterprise. The OPC technology discussed in this paper is one of the methods to solve these questions above.
