一种基于DSP的远程接口单元设计

Design of a Remote Interface Unit Based on DSP

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DSP,设计了一种远程接口单元。该远程接口单元,选择DSP作为处理器,FPGA作为IO管理单元,实现了模拟量采集、离散量采集、离散量输出、HB6096总线通讯和GJB289A总线通讯。经系统联试试验证明,远程接口单元工作稳定可靠,具备一定的工程实用价值。

The Remote Interface Unit(RIU) is the important part of the the airborne electromechanical system.RIU has been widely used in the new aircraft design.This paper designs a kind of RIU based on DSP.The RIU chooses the DSP as the processor,takes the FPGA as the IO management unit and realizes the analog quantity collection,discrete magnitude collection,discrete magnitude output,HB6096 communication and GJB289A communication.The system experiments shows that the designing RIU works stably and reliably,and it has the engineering practical value.
