摘要
综合模块化航空电子(IMA)是一种建立在分布式计算环境之下的可以实现软硬件分离的架构,它可实现硬件模块应用的动态软件分配。即,IMA系统可以根据功能性和资源可用性来选择不同的配置。本文主要关注了IMA重构中涉及到的安全性及人素问题。解析了重构的过程以及人素与自动化方面的技术。事实证明,某些情况下安全有效的配置需要具备故障识别、安全要求、任务调度及资源分配限制以外的知识。并且平台的安全性设计还取决于人机系统是否实现了最佳结合。
Integrated modular avionics makes use of distributed computing resources, and such a structure is able to separate software and hardware, so as to make hardware modules reconfigured in a dynamic way. In other words, functions and resources can decide ways of configuration and reconfiguration. This paper addresses the human factors issues and safety problems in IMA reconfiguration from the perspective of reconfiguration process and the relationship between human factor and automation. It is proved that aircraft safety relies not only on such factors as fault detection and resource allocation, but on a human-machine system that best combines human factor and safety design.
