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 ,Dis tributedControlSystem)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。
Fieldbus Control System (FCS) is the development direction of modern industrial control network. On the one hand, the field bus control system is compared with the traditional distributed control system (DCS) to study the progress of the field bus control system; on the other hand, the characteristics of the different field buses, especially the real-time Closely related to the media access control methods were discussed.
