摘要:

围绕新一代先进航空飞行器,对高度综合化飞行器管理计算机的需求,国内外争相开展新型容错计算机的相关技术研究；ARINC 659背板总线因其强实时性、高带宽、抗干扰和容错能力强而著称,现已成为航空电子设备标准背板总线,也已成为模块化、综合化架构航电系统的关键技术;因此,基于ARINC 659总线容错计算机的研制已逐渐成为高可靠航空电子系统研究的热点和重点;提出了基于ARINC 659总线的新型容错计算机构架设计方案、余度管理以及故障实时诊断与隔离等关键技术。

Abstract:

For integrated requirement of the vehicle management computer about new generation fighter plane, at home and abroad, the researching of technology for the Innovative fault-tolerant computers system is developing.The ARINC659 backplane bus is famous as a key shared resource in the integrated avionics system, and it has remarkable advantages such as real time, throughput, immunity and tolerance from various upsets in a harsh environment. It is slated to become the standard backplane bus for commercial avionics, and the backplane bus is one of the key technologies in integrated modular avionics system. Lately years, consequently the research of fault tolerant computers based on ARINC659 is key point and hot point in the high dependable avionics system. The paper indicates the new fault tolerant computer architecture based on ARINC659, redundant management, fault diagnosis and seclusion.
