摘　　要：针对“集中控制”式远程接口单元各功能模块间的高度耦合问题,将集散控制系统引入到远程接口单元的架构设计中,配置了一级控制器和二级控制器,一级控制器完成飞机总线与远程接口单元内部的局部总线之间的数据传输,二级控制器独立完成轻量级的配置、管理与控制任务。性能对比分析表明,设计能有效提高远程接口单元的处理速率,降低功能耦合度,增强任务可靠性,且有利于模块化设计,具有工程实用价值。Aiming at the problem of high coupling between functional modules of the RIU in the CCS mode.This paper introduces the DCS into the architecture design of the RIU and configures a primary controller and a set of secondary controllers within it.The primary controller completes the data transmission,while secondary controller complete lightweight computing,management and control tasks.The performance comparison proves that proposed method can effectively improve the processing rate,reduce the functional coupling degree,enhance the task reliability,and is beneficial to the module design.
