摘要：

为提高民机分布式综合模块化航空电子(distributed integrated modular avionics, DIMA)系统应对飞行任务切换和资源失效的能力, 分析了DIMA动态重构环境及动态重构机制, 形成了面向任务的动态重构策略。首先, 提出“任务-功能-资源”间的关系矩阵及动态重构有效性评价体系。然后, 引入组合优化赋权法计算不同任务模式下功能应用的优先级权重。最后, 用实例分析对比了面向任务的动态重构策略与普通重构策略在不同任务模式下系统资源对系统功能完整性的支撑程度。研究结果表明, 随着模块故障数量的增多, 面向任务的动态重构策略可以显著提高动态重构的有效性。

Abstract:

In order to improve the ability of civil aircraft distributed integrated modular avionics (DIMA) system to cope with mission switching and resource failure, the dynamic reconfiguration environment and mechanism of DIMA are analyzed. And the task oriented dynamic reconfiguration strategy is proposed. Firstly, the relationship matrix of "task-function-resource" and the effectiveness evaluation system of dynamic reconfiguration are proposed. Then, the combined optimization weight method is introduced to calculate the priority weight of function application in different task modes. Finally, an example is used to analyze and compare the support degree of system resources to system functional integrity between task oriented dynamic reconfiguration strategy and common reconfiguration strategy under different task modes. The research results show that the task oriented dynamic reconfiguration strategy can significantly improve the effectiveness of dynamic reconfiguration with the increasing number of module failures.

Key words: avionics system, distributed integrated modular avionics (DIMA), dynamic reconfiguration, combination weighting, effectiveness
