基于分布式航电系统的系统管理功能设计

System Management Function Design Based on Distributed Avionics System

针对分布式航电系统设计中对资源组织的灵活性需求,为提升系统资源利用率,提出了一种基于分布式航电系统的系统管理配置方法,引入功能组件、服务角色、组件实例、系统管理代理,定义组件到组件的消息以及系统配置信息表。通过系统管理策略实现组件实例的重启、组件实例的主从备份、组件实例的冷备份,从而增加系统的任务可靠性。在不更改应用组件功能及接口控制文件(ICD)接口的前提下,实现分布式航电系统的系统重构。

Aiming at the flexibility requirement of resource organization in the design of distributed avionics system and improving the utilization rate of system resources,a system management configuration method based on distributed avionics system is proposed,which introduces functional components,service roles,component instances and system management agents,and defines component-to-component messages and system configuration information tables.Through the system management strategy,the restart of the component instance,the master-slave backup of the component instance,and the cold backup of the component instance are realized,thus increasing the task reliability of the system.The system reconfiguration of distributed avionics system is realized without changing the functions of application components and ICD interface.
