基于以太网的民用飞机客舱网络架构设计

摘要

客舱系统是民机航电系统的重要组成部分,主要包括客舱核心系统、机载娱乐系统和外部通信系统三大部分.本文通过对客舱典型业务、客舱网络设计要求和客舱常用设备的分析,结合对以太网技术的研究,设计出一套满足当前客舱典型业务的一体化网络架构方案,并对该网络架构中重要连接设备做出了详细功能说明的,最后使用OPNET网络仿真工具对该网络架构进行了仿真验证,表明了客舱一体化网络架构的优越性和可行性.%The cabin system is an important part of the civil aircraft avionics system, mainly consisting of the cabin core system, the airborne entertainment system and the external communication system. This paper designs an integrated network architecture to cover all cabin typical business senarios through the analysis of the typical cabin business services, the principle of cabin network design and the common devices in cabin application based on the existing ethernet technology. Then it also states detailed function requirements about important communicated devices in cabin networks, and uses OPNET software to get the simulation result to demonstrate the feasibility and superiority of the integrated network architecture designed in this paper.
