小型飞机先进综合座舱电子系统架构研究

以Garmin1000系统为例,从系统功能、基本架构、容错策略和通用性方面分析了小型飞机先进综合座舱电子系统架构的设计特点。先进综合座舱电子系统架构包括了设备级和系统级两个层面,在设备级阐述了航电设备集成化的发展趋势,在系统级采用了不同的容错策略,保证系统规模最小化时容错能力达到最大化。同时,网络应用增强了系统架构的通用性,支持多种系统规模的扩展。

Research on Advanced Integration Cockpit Electronic System Based on Small Airplane

This paper analyses Garminl000 system characters based on system function, data relation, system archi- tecture, fault- tolerant, maintenance and expansibility. Architecture of advanced integrated cockpit electronic system in- cludes device level and system level. At the device level high integration of avionics has become a distinct tendency. At the system level fault- tolerent policies ensure system reliability to reach the higest level under the least scale, which ap- plied in Display- control, communication- navigation and flight instrument three sub- systems. At the same time network application enhances system flexibility and makes it support manifold expansion.
