一种民用客机智能诊断架构及验证策略研究

随着飞机机载电子系统结构越来越复杂,机载设备的智能诊断日益繁杂,对复杂机载电子系统的智能诊断系统体系结构设计实现和综合验证提出了挑战。本文首先对比分析了两种代表机型的CFDS和CMS体系结构、智能诊断方法。最后介绍一种大型民用客机智能诊断架构,并对机组告警系统的实现架构和验证策略进行了详细阐述,并通过试验验证了该设计实现的实用性,并可将此方法扩展到飞机PFD、发动机、显示管理等其他系统,具有较强的扩展性。

As the structure of airborne electronic system becomes more and more complex,the intelligent diagnosis of airborne equipment becomes more and more complex,which challenges the design,implementation and comprehensive verification of the intelligent diagnosis system architecture of complex airborne electronic system.Firstly,the architecture and intelligent diagnosis methods of CFDS and CMS are compared and analyzed.Finally,an intelligent diagnostic architecture for civil aircraft is introduced,and the implementation framework and verification strategy of the crew alarm system are elaborated in detail.The practicability of the design and implementation is verified by experiments.This method can be extended to other systems such as aircraft PFD,engine,display management and so on.It has strong expansibility.
