航空电子系统故障管理体系结构研究

军用航空电子系统承载着战机绝大多数作战任务,是决定战机作战效能的重要因素.故障管理体系结构及技术是保证航空电子系统和战机安全性的重要技术之一.概述了航空电子系统含义、功能分配结构及功能与资源的映射关系,总结了航空电子系统顶层设计原则,可指导故障管理体系的构建.探讨故障管理的含义和任务,论述联合式和IMA两类航电系统故障管理结构,并就其共性问题进行探讨.最后试探性地提出故障管理体系结构需进一步研究和解决的问题.

Research on Fault Management Architecture of Avionics System

The avionics system takes on the most battle missions of fighter,which is an important factor that can decide combat effectiveness.Fault management achitecture is one of key technologies to ensure the safety of avionics system and fighter.The concept,function allocation hiberarchy of avionics system and mapping relationship between avionics functions and resources are analyzed,the top level design principles of avionics system are summarized to guide the construction of fault management architecture.The meaning and roles of fault management are explored,the fault management architectures of federated system and IMA system are discussed,whose common problems are explored.Finally,some problems about fault management architecture of avionics system to be further studied and solved are exploringly presented.
