ARINC429总线发送端软硬件隔离控制技术研究

摘要

ARINC429 bus is a common bus used in civil and military aircraft.Its interconnection mode is point to point interconnection mode,which supports one sender and one receiver or one sender and multiple receiver.Using hardware/software isolation control technology,ARINC429 bus transmitter realized interconnect structure with generalized multiple senders and one receiver,which reduced the software/hardware cost and complexity of ARINC429 bus interface connected with a redundant computer and reduced the system cost.%ARINC429数据总线是民用和军用飞机上普遍使用的一种互联总线,其互联模式为点对点互联方式,支持一发一收或一发多收.采用ARINC429总线发送端软硬件隔离控制技术实现了ARINC429总线广义多发一收互联结构,降低了与余度计算机互联的设备的ARINC429总线接口软硬件成本及复杂度,降低了系统成本.
