A design of real-time dual redundancy system based on VxWorks

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.
