综合模块化航空电子系统的故障预测与健康管理技术

摘要

The avionics system is one of the most vital factors which can affect performance of modern planes and it is very important for research of the fault prognostic and health management(PHM)technology to ensure the safety of the avionics sys⁃tem and the whole plane. According to the integrated modular development tendency of the avionics system,a PHM system is proposed for open type and modular architecture. The hierarchical function allocation of avionics system is utilized in this paper to design the architecture of the PHM system and the related technology detail by the analysis of the critical subsystems. The analysis result shows that the designed PHM system can meet the demands of standardization,hierarchy,modularization and openness of avionic systems.%航空电子系统是保障现代飞机性能的非常关键因素之一，对其开展故障预测及健康管理技术的研究是保证飞机安全性的重要课题。针对航空电子系统综合模块化的发展趋势，研究了一种面向其开放式与模块化架构的故障预测与健康管理系统。通过对综合模块化航空电子系统的分层结构分析，结合关键子系统展开设计，包含了飞机PHM系统的体系结构设计及相关环节的技术实现。结果表明该体系结构可满足航空电子系统标准化、层次化、模块化、开放性的要求。
