摘要
介绍了现场总线的概念及其特点,通过国内外FCS系统的应用案例和故障分析,从技术经济角度出发,得出结论:FCS将是今后的发展方向,但是现阶段现场总线技术受到其实时性、稳定性、确定性以及配套设备成本等因素的制约,FCS尚不能取代DCS,而只能是DCS大构架下的一个重要分支和有益补充。
In the article, the concept and feature of FCS is introduced. According the analysis of case study for FCS projects from domestic and overseas, it give the conclusion from the technical and economic perspective that FCS will be the development direction in future, but at the moment FCS can not displace DCS because of the restrict of instantaneity, stability reliability and cost etc. FCS will be key branch and useful supplement under DCS framework.
