摘要
介绍了DCS中冗余设计的几种方法,其中涉及电源、控制器、I/O模块、通信电缆以及整个控制系统的冗余问题,并对冗余方式的可靠性进行了分析.
Several methods of the design of redundancy of distributed control systems are introduced. These include the redundancy for power supply controller, I/O modules, communication cables and the integral system. The reliability of the redundancy is also analyzed.
