机载分布式系统管理中消息交互机制探究

Study of message interaction mechanism of the airborne distributed management system

摘要:

NATO STANAG 4626 ASAAC已广泛应用于综合化模块化航空电子系统,在STANAG 4626中,分布式通用系统管理划分为四个功能组件(健康管理、故障管理、配置管理和安全管理),通过对四个功能组件间的消息通信过程进行分析,提出一种基于分布式通用系统管理的消息交互机制,具体包括消息类型划分、消息封装机制、消息收发派遣机制、消息底层传输机制,满足通用系统管理消息通信中多节点、多数据流通信需求,减少系统设计冗余。

Abstract:

NATO STANAG 4626 ASAAC is wildly used in the comprehensive modularized avionics system. For the STANAG 4626, the distributed generic management system is divided into four function modules namely health management, fault management, configuration management and security management. This paper proposes a message interaction mechanism, including message classification, message encapsulation, message dispatch and message underlying transport, of the distributed generic management system based on analyses of communication processes among the four function modules. The results show that the proposed message interaction mechanism can be used to meet requests of communication with multiple data flows among the interactive nodes and reduce the redundancy of system design.
