摘　　要：远程接口单元是飞机机电系统的重要组成部分,在新型飞机设计中,远程接口单元的应用越来越广泛。本文基于ARM,设计了一种双余度远程接口单元(DRIU)。该远程接口单元,具备双余度飞管总线接口与双余度输入/输出接口,选择ARM作为处理器,双余度同时工作实现了飞机机电系统数据采集、集中解算和分布控制。经系统联试试验证明,双余度远程接口单元可以提高系统工作任务的可靠性,具备一定的工程实用价值。The Remote Interface Unit(RIU)is the important part of the airborne electromechanical system which is widely used in the new aircraft design.This paper designs a kind of Dual-Redundancy RIU based on ARM.The DRIU has the dual-redundancy vehicle management system bus interface and dual-redundancy input/output interface.The DRIU chooses ARM as the processor,realizes data collection,centralized procession and distributed control with dual channel working at the same time.The system experiments show that the designing DRIU works stably and reliably,and it has the engineering practical value.
