摘要
现场总线控制系统 (FCS ,fieldbuscontrolsystem)是现代工业控制网络的发展方向。本文一方面从纵向的角度将现场总线控制系统与传统的集散控制系统 (DCS ,distributedcontrolsystem)进行比较 ,研究其进步性 ;另一方面从横向的角度对不同现场总线的特点尤其是与实时性密切相关的媒体存取控制方法进行了对比探讨。
FCS is the direction of the development of modern industry control network.From the point of lengthways view,FCS is compared to DCS and its advancement is discussed.And from the point of transverse view,the different characters is discussed,focusing on the different methods of media access control,of popular FCS.
