摘要
为了提高飞机机载机电系统的信号处理终端设备——远程接口单元(RIU)的通用性、配置的灵活性、故障后自修复能力等,研究了通用远程接口单元(GRIU)的系统架构。在硬件结构上,由开关矩阵桥接各类机载机电信号;应用FPGA动态局部重构(DPR)技术,由模块化BIT文件流实现机载机电子系统的功能配置和故障后重构。介绍了RIU的作用和特点,DPR的设计方法,并以起落架系统和液压系统为例,给出了GRIU在机载机电系统中的工程应用方法。
In order to improve the generality, flexibility and self-repairing capability of the remote interface unit （RIU） as a terminal equipment of signal processing of generic remote interface unit（GRIU） is proposed cuits and airborne signals for airborne electromechanical systems, a new design idea ~ The flexible connection between signal conditioning cir- is due to the advantages of switch matrix. The function distribution and post-fault reconfiguration of airborne electromechanical subsystems by using dynamic partial reconfiguration（DPR） with the configuration of BIT files are to realized. The features and functions of RIU and the design procedures of DPR are introduced, so as the engineering application of GRIU in landing gear and hydraulic system.
