新一代民用客机自主式数据总线

A New Autonomous Data Bus in a Airliner

本文在简要阐述 ARINC 429 和 MIL-STD-1553B 总线应用所受限制的基础上,介绍了90年代美国民航界推出的一种自主式数据总线 ARINc629的设计要点,包括其通信协议。各终端信源数据在总线上的周期传输和非周期传输、信息传输的种类和方法及终端的功能框图,最后给出了此总线在新一代民用机中的应用情况。

Starting from a exposition of the application limitations of ARINC 429 and MIL8-STD-1553B data buses,this paper introduces a new generation of airborne data bus ARINC 629,which has been brought forward by the civil aviation circles of the U.S.A.,including the origins,communication protocol,periodic and aperiodic transmission,the varieties and modes of message transfer and the terminals'functional block diagram and its key technique.The application of ARINC 629 in a new generation of air- lincrs is also set forth
