基于VxWorks下PNN故障诊断的冗余容错系统
Redundant fault-tolerant system based on VxWorks and fault diagnosis of PNN
摘要
Abstract
Aiming at the requirements of high reliability for aerospace measurement and control systems, a design of redun-dancy and fault tolerance based on Compact PCI(CPCI)bus is proposed. The upper computer adopts the embedded sys-tem based on VxWorks to ensure the real-time performance. And the high availability hot-swap technology based on VxWorks embedded system is used in the system and an advanced fault diagnosis method based on the Probabilistic Neu-ral Networks(PNN)is proposed for checking the faults of hot-redundancy equipments on line. Simulation and experiment results show that the system can satisfy the requirement of redundancy and fault tolerance. This design method can effec-tively improve the reliability of the system.关键词
