机载网络作为飞机航电系统的关键技术之一, 其实时性能、容错能力以及网络行为的正确性将影响到飞机的整体性能, 对其合理的管理可有效发挥航电系统的性能。基于对航电系统网络架构进行的研究, 提出了一种采用AFDX为主干网络的级联式双中央处理机航电系统架构模型, 在此模型的基础上结合AFDX网络的特点和TCP/IP网络管理的方法, 进行了AFDX网络管理技术的研究, 对AFDX网络管理方法和实现方式进行了分析, 提取其构型管理、故障管理、配置管理等关键需求并在VxWorks653操作系统中实现该网络管理软件。

Airborne network is one of the key technologies of aircraft avionics system. The real time performance, fault tolerance and correctness of network behavior of it will affect the overall performance of aircraft, and a proper management of it will give an effective play to the performance of the avionics system. Based on research for avionics system network architecture, an avionics system architecture module with cascade double CPC was proposed, taking AFDX network as the backbone network. On the basis of which, as well as in combination with the characteristics of AFDX network and method of TCP/IP network management, research on AFDX network management technology was carried out. Methods of AFDX network management and its implementation were analyzed, such key requirements as its architecture management, fault management and configuration management were proposed, and the network management software was implemented in VxWorks653 operating system.
