摘要
综述了民机航空电子体系架构从联邦式体系(如A310)、综合模块化航电体系IMA(如B777)乃至分布式综合模块化航电体系DIMA(如A380和B787)的发展过程,对民机典型互连协议进行了比较,指出航空电子全双工交换式以太网AFDX互连技术能够满足新一代民机航电"信息一体化"的发展需求,并以当代先进大型民机A380为例,说明其如何采用AFDX互连构筑DIMA。最后对我国大型飞机航电系统发展提出一些建议。
The evolution of civil avionic architecture is surveyed, which goes from federal architecture, through Integrated Modular Avionics （ IMA）, to Distributed Integrated Modular Avionics （DIMA）. Three kinds of representative interconnection protocols are Switched Ethernet （AFDX） is a good choice to satisfy studied. It is indicated that Avionic Full Duplex the demand of information integration. The avionic architecture deployed in A 380 avionics system is analyzed, and finally a suggestion is presented for development on avionics in domestic large airplane.
