一种策略可配置的IMA系统故障管理方法

A Policy Configurable Method for Fault Management of IMA System

随着综合化模块化航空电子(IMA)系统的综合化程度增加,其故障发生概率及类型增多,且IMA系统在功能升级、集成过程中,其故障管理方式不断迭代、管理难度增加。提出一种可灵活策略、可配置的故障管理方法。方法基于IMA平台构建于分区OS上,参考ASAAC标准管理层级,提出预先配置故障管理策略及多级权限的管理机制,解决了传统故障的过滤、诊断及处理方式与应用程序强耦合问题,以及由于故障处理而导致系统运行不确定性问题。所提方法满足IMA系统在不同机型不同阶段的故障管理需求,最终满足新一代IMA系统在移植性和确定性方面的要求,提高系统的安全性与可靠性。

With the improving of the degree of integration of IMA system,the occurrence probability and types of faults increase,and in the process of function upgrading and integration of IMA system,it′s fault treatment keeps iterating,and the management difficulty increases.This paper presents a fault management method with flexibly policy configuration for IMA system.Based on the IMA platform building on the partition OS and referring to the management levels of ASAAC standard,the method proposed pre configured fault management strategy,multi level permission management mechanism,which solved the problem in the traditional way of fault filtering,diagnosis and handle strong coupling with the application,as well as uncertainty of system operation caused by fault treatment.The proposed method can satisfy fault management requirements of IMA system in different stages or aircrafts,and finally meet requirements of new generation IMA system in the aspects of portability and certainty,and improve the safety and reliability of the system.
