随着计算机、通讯技术、微电子技术和网络技术的不断进步和发展,计算机通信技术正向着高速、实时、分布、安全的方向发展,同时也给航空电子系统的发展提供了更好的平台和基础,航空电子系统从综合化向着以信息交换为中心、高度综合化的深层发展,对超高速电子数据连接的需要也日益增长,并且要求通过数据综合和高速网络来提高其性能.空中客车公司在其最新研制的A380飞机上率先采用先进的全双工交换式以太网AFDX（Avionics Full DupleX Switched Ethernet）航空数据总线,能提供很高的数据传输速率,并大幅减轻机上的电缆重量.AFDX为航空电子设备之间的数据交换提供了电气和协议的规范,它是建立在空中客车公司最早提出的AFDX概念之上,其数据传输速率是ARINC 429的几千倍.
本文介绍了航空电子总线的发展历史和国内外研究现状,阐述了以太网发展历史和背景知识,从航空电子网络特点出发指出了以太网所具有的优点和存在的问题,从而引出国外航空电子领域正在使用的AFDX航空总线.
本文在分析新一代航空电子系统特点的基础上,介绍AFDX航空电子总线的结构及其原理、介绍了AFDX的通信协议和硬件实现方案.简单介绍了ACTEL公司为航空电子全双工交换式以太网提出的总体设计方案,其中重点介绍core10/100 MAC模块的功能和内部功能块器件.

Along with the computer,the mechanics of communication,the microelectronic technology and the networking progress unceasingly and develop,the computer communication is turning toward high speed,real-time,distributed,the safe direction to develop,simultaneously also gave the avionics system's development to provide a better platform and the foundation,the avionics system turns toward from the integration take the exchange of information as the center,highly the integrated in-depth development,also day by day grew to the supervelocity electron data connection's need,and requested through the data comprehensive and the high speed network enhances its performance.The Airbus company takes the lead on its newest development's A380 airplane to use advanced full-duplex exchange type ethernet AFDX (Avionics Full DupleX Switched Ethernet) the air data main line,can provide the very high data transfer rate,and reduces on light machinery's electric cable weight largely.AFDX was between aviation electronics' data exchange has provided electrical and the agreement standard,it was the establishment,in the Airbus company proposed most early above the AFDX concept,its data transfer rate was ARINC 429 several thousand times.this article introduced the avionics main line's historical development and the domestic and foreign research present situation,elaborated the ethernet historical development and the background knowledge,embarked from the avionics network characteristic had pointed out the ethernet had merit and existence question,thus drew out the overseas avionics domain the AFDX aviation main line which used.this article in analyzes the new generation avionics system characteristic in the foundation,introduced that the AFDX avionics main line's structure and the principle,introduced the AFDX communication protocol and the hardware realize the plan.Introduced simply ACTEL Corporation the overall project design which proposed for the avionics full-duplex exchange type ethernet,introduces core10/100 with emphasis the MAC module the function and the internal function block component.
