摘要
研究了FC-AE-1553(Fibre Channel-Avionics Environment-1553,光纤通道-航空电子环境-1553)网络的计算机仿真问题。从FC-AE-1553网络的基本原理出发,提出了网络结构模型和数据传输控制方法;在OPNETModeler中创建了FC-AE-1553网络节点模型和FC交换机模型;采用数据传输控制方法控制整个FC-AE-1553网络的数据传输,对航空电子典型拓扑网络进行仿真。通过仿真实验与结果分析证明了FC-AE-1553网络具有良好的实时性能,采用提出的数据传输控制方法比MIL-STD-1553B的数据控制方法有更高的网络吞吐能力和更强的适应性。
The problem of computer simulation for FC-AE-1553 （Fibre Channel-Avionics Environment-1553） network is studied. Based on the basic principle of FC-AE-1553 network,a network structure model and a control algorithm of data transmission are proposed.A FC-AE-1553 network node model and a fibre channel switch model are set up in OPNET Modeler.The whole data transmission process of FC-AE-1553 network is controlled by the proposed control algorithm of data transmission.A typical topological network for avionics is simulated.Good real-time performance of FC-AE-1553 network is validated with simulation tests and results analysis.The analyzed results show that the network throughput using proposed control algorithm of data transmission can be doubled nearly.
