基于确定策略的机载分布式系统多级重构方法研究
|
摘要
随着航空电子系统规模和复杂度的迅速增长,新一代分布式航空电子系统采用综合化模块化(IMA)的设计思想,综合化在提高飞机作战性能、降低成本等优势的同时,也带来了资源利用率、可靠性、安全性等方面的挑战。通常会采用系统重构的方法提高系统的可靠性和安全性,一般的系统重构方法将影响整个系统的运行,会带来很多不确定性的问题。提出一种基于确定策略的机载分布式系统多级重构方法,通过分级管理方式控制系统重构的影响范围,提高了重构的速度;通过基于静态配置的系统重构策略确保了重构过程本身的可靠性和安全性;通过系统资源的动态管理,提高了分布式系统对资源的利用率。最终能够满足新一代分布式航空电子系统在重构速度、可靠性和安全性以及系统资源的利用率等方面的要求。
As the rapid increase of scope and complex for aviation electronics system,the new distributed aviation electronics system employed IMA design philosophy. IMA raised the war power of the airplane and reduced the cost price,but it introduced the challenge of resource availability,reliability and safety.As usual,we employ system reconstruction to improve the reliability and safety. Ordinarily reconstruction method will affect the running of the whole system and introduce many uncertainty questions. This paper proposed a kind of airborne distributed system multilevel reconstruction based on fixed strategy. It controlled the scope of the reconstruction through the multilevel management,thus speeding up the reconstruction. It insured the reliability and safety of the reconstruction process through static configuration. It improved the resource availability through managing the system resource dynamically. Finally,it can satisfy the requirement of the new distributed aviation electronics system for reconstruction speed,reliability,safety and resource availability.
