基于分布式IMA平台的系统健康管理的设计与实现

随着分布式综合模块化航电（分布式IMA）系统的深入应用，需要针对分布式IMA平台的健康监控、故障管理、系统容错重构、系统运行日志等健康管理能力进行进一步研究。本文深入研究了 VxWorks653操作系统中的健康监控机制和ASAAC标准中的系统管理技术，以此为基础设计并实现了分布式IMA平台级和系统级的健康管理方案。在本文的方案中，对 VxWorks653操作系统的健康监控机制进行改进，使其能够满足自定义的故障处理需求，将ASAAC标准中的系统管理技术和IMA系统内故障信息的收集相结合，实现了对IMA系统内各进程、各分区、各模块乃至整个IMA系统进行健康管理。

Design and Implementation of System Health Management Based on Distributed IMA Platform

Along with the further use ofdistributed IMA system,the capability of health monitor,fault management, system reconfiguration and system running log needs to be further studied.This paper presents a research on the mechanism of health monitor in VxWorks653 system and the technology of system management in the ASAAC standard,which isthebasis of the design and implementation of platform level and system level of the health management in distributed IMA system. This methodimproves the mechanism of health monitor in VxWorks653 system so as to meet the defined fault processing needs, combining the technology of system management in the ASAAC standard and the fault information management in IMA system.In this way, health management is implemented in all processes,partitions,modules and the whole IMA system.
