集成模块化航空电子设备（IMA）已发展为分布式集成模块化航空电子设备（IMA 2G）。作为分布式集成模块化航空电子设备(DIMA)的典型特征，动态重构已成为研究重点。下一代 IMA 平台应包括重新配置功能，以限制硬件故障对飞机运行可靠性的影响。架构分析与设计语言(AADL)可以有效支撑IMA物理架构的设计和仿真。本文在分析重配置需求的基础上提出了DIMA平台功能架构框架，应用AADL动作模型构建了DIMA动态重配置的故障检测与识别、重配置策略搜索与执行等功能动作特征，并对其实时性进行了分析，为DIMA动态重配置的实现提供设计依据。
Integrated Modular Avionics (IMA) has developed into Distributed Integrated Modular Avionics (IMA 2G). As the typical characteristic of Distributed Integrated Modular Avionics (DIMA), dynamic reconfiguration has become the research emphasis. The next generation of IMA platforms should include reconfiguration capabilities in order to limit the effect of hardware failures on aircraft operational reliability. The Architecture Analysis and Design Language (AADL) could brace the IMA physical architecture's design and simulation effectively. This paper proposes the DIMA platform functional architecture framework based on the analysis of reconfiguration requirements, and applies AADL action model to build the functional action features of DIMA dynamic reconfiguration, such as failure detection and recognition, search and execution of reconfiguration strategy, and also analyze its real-time performance to provide design basis for the realization of DIMA dynamic reconfiguration.
