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。不同飞机对于远程接口单元的需求不尽相同,某型飞机远程接口单元不仅实现机电系统数据的采集功能,而且需要完成机电系统的健康管理功能。针对该需求,本文设计了一种基于PowerPC处理器的双余度远程接口单元,该远程接口单元接口资源丰富,处理能力强,经系统联试试验证明,该远程接口单元工作可靠,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.RIU has been widely used in the new aircraft design.Different system frame has different requirements for RIU.A certain system frame not only needs RIU to fulfill data collection of lectromechanical system,but also to implement Prognostics Health Management(PHM)function.In order to solve this problem,this paper designs a kind of Dual-redundancy RIU based on PowerPC.The DRIU has abundant interface and excellent computing and processing capability.The system experiments show that the designing DRIU works stably and reliably,and it has the engineering practical value.
