摘　　要：阐述了基于VxWorks操作系统下的CPCI总线实时计算机双机冗余的特点。从增加实时计算机系统可靠性的角度对实时计算机进行了双冗余总体设计。结合软硬件实现了双冗余实时计算机输入、输出接口的逻辑控制,给出了故障监测、智能切换的硬件与软件框图。最后略述了基于VxWorks操作系统下的CPCI总线实时双冗余计算机在自动控制系统中的应用情况。This paper elaborates on the characteristics of CPCI bus real-time computer dual redundancy based on VxWorks operating system and makes a dual-redundant total design for a real-time computer from the view of increasing its system reliability. It achieves logic control of dual redundant real-time computer input and output interface with the combination of hardware and software, and gives the hardware and software frame for fault monitoring and intelligent switching. Finally, it discusses briefly the applications of CPCI bus real-time dual redundancy computer in automatic control system based on VxWorks operating system.
