流程工业控制系统中多总线技术的应用研究

Study on the Application of the Multi Bus Technology in Industrial Process Control System

在较大规模的流程工业控制系统中,往往单一的现场总线技术很难实现真正意义上的分散控制.本文以实际生产为例,针对系统中的管理层、车间层和设备层等的不同特征,选用多总线耦合技术,设计了多总线控制系统.

In the industrial process control system in large scale , it ’ s frequently difficult for the single fieldbus technology to realize decentralized control on real significance .With reference to the real production , this paper selects multi bus coupling technique to design multi bus control system according to the different fea -tures of management layer , workshop layer and equipment layer in the system .
