Abstract: The status of domestic and abroad researches on high-availability fault tolerance of measurement and control systems is analyzed, and a design of high-availability hot-swap based on compact PCI (CPCI) bus is proposed to solve the problems in applying and testing the modular redundancy and fault tolerance in the measurement and control systems of weapons. A semi-physical simulation platform that could test the hot-swap and hot-redundant systems is developed to verify and analyze the reliability of a controlled object in experimental hot-swap systems. The result shows that the system is stable and excellent. The observability of different objects in hot-swap and hot-redundant systems is achieved by studying the high-availability hot-swap and hot-redundant systems.

Key words: control science and technology, redundancy, fault tolerance, hot-swap, compact PCI bus
