摘要
机载数据总线是现代航空电子系统的重要组成部分，而AFDX是一种新型航空电子数据通信总线协议。文章分析了AFDX网络的组成、协议标准，进一步阐释了它的关键技术，并对其测试技术进行了研究。与传统机栽总线相比，AFDX具有带宽宽、实时性好、可靠性高等特点，因此对AFDX网络技术进行研究具有非常重要的意义。
The avionics bus is an important part of the modern avionics system. This paper introduces a new avi- onics bus protocol - AFDX. Analyzing the architecture and protocol of AFDX, this paper expatiates on its key technology further, and discusses its test technique. Compared with the traditional avionics bus such as ARINC429 and 1553B, AFDX is good at bandwidth, low latency and reliability. So studying its technology is more and more important.
