Hot-swap and hot redundancy technology for high-availability Compact PCI system

Motivated by the challenging requirements of optimal fault tolerance and real-time response in the Compact PCI (CPCI) measurement and control systems, a design of a high-availability hot-swap system based on VxWorks operating system is proposed. In addition, multiple methodologies are designed and applied to guarantee operational safety during the hot-swaps. An external experimental measurement platform is developed to analyze the reliability of the controlled entity in the hot-swap hot redundancy experimental system. The experimental results prove that this hot-swap hot redundancy system achieves highly stable performance as designed.
