摘　　要：民机航电功能的实现通常涉及多个系统,在设计过程中还需要同时兼顾安全性,因而系统架构的综合设计日趋复杂。然而当前民机航电架构设计中缺少安全性考虑,导致设计不足。鉴于此问题,提出面向安全的民机系统架构设计流程,从需求、功能、逻辑、物理分层级进行架构设计,统一定义和分解架构元素,建立每一层模型之间的纵向映射关系,实现了功能的综合分析和多系统集成的架构设计。最后,通过对物理架构故障遍历的方式对架构模型进行故障树分析。姿态显示架构设计的实践结果表明,该方法可以有效应对复杂系统的架构设计,提高系统的整体安全性和工程效率,并促进系统质量的持续优化。The implementation of civil aircraft avionics functions usually involves multiple systems.During the de-sign process,it is also necessary to consider safety at the same time.The comprehensive design of system architec-ture is becoming increasingly complex.However,the current design of civil aircraft avionics architecture lacks safe-ty considerations,resulting in insufficient design.In view of this issue,a safety-oriented architecture design process for civil aircraft systems is proposed.The architecture design is carried out at the requirements,functions,logic,and physical hierarchical levels,with unified definition and decomposition of architecture elements.Vertical map-ping relationships between each layer of models are established,implemented comprehensive functional analysis and architecture design for multi-system integration.Finally,perform fault tree analysis on the architecture model by traversing physical architecture faults.The practical results of attitude display architecture design indicate that this method can effectively handle the architecture design of complex systems,improve the overall safety and engineer-ing efficiency of the system,and promote continuous optimization of system quality.
