Abstract: In order to simplify avionics bus system structure and reduce bus power consumption,a PON structure fiber bus protocol used in avionics environment is proposed,which is based on the analyses of avionics bus technology demand.The protocol’s transmission characteristics and key technology are analyzed.The process model,node model and network model of the protocol are established on the OPNET software platform using three levels’ model mechanism.The protocol proposed and FC-AE-1553B are compared in simulation,and the results show that this protocol has merits of simple structure,low consumption,high reliable performance,low delay time and high transmission data rate.

摘要: 以简化航电总线系统结构、降低总线功耗为目的,在分析了航电总线技术要求的基础上,提出了一种适用于航空环境的PON结构光纤总线协议。分析了该协议的传输特性与关键技术,在OPNET软件平台下采用三级建模机制,建立该协议的进程模型、节点模型和网络模型。通过对协议的仿真特性分析,以及与FC-AE-1553B(Fiber Channel-Avionics Environment-1553B光纤通道-航空电子环境-1553B)的仿真比较,说明该协议具有拓扑简单、功耗低的网络互联结构,也验证了其低延迟、高传输速率的传输特性。
