| 摘 要： | 在离散控制系统(DCS)中,冗余技术被广泛采用.随着一些新的控制器,如以ARM系列控制器为代表的RISC控制器的出现,使得DCS控制系统的架构设计有了更多的选择,新架构的DCS控制系统可能具有更高的稳定性和更高的性价比.介绍一种基于ARM控制器的分布处理单元,并基于这种处理单元分析了DCS控制系统的分布处理单元冗余设计和网络冗余设计.

| Abstract: | The redundancy technology is widely used in Distributed Control System(DCS).New kinds of controllers such as the RISC controller represented by ARM controllers provide more selections for framework design of DCS,and the DCS with new framework can be characterized by high stability and price-performance ratio.A new Distributed Processing Unit(DPU) based on ARM controller is presented,and the DPU redundancy design for DCS as well as the network redundancy design is analyzed. |
