摘要
光纤通道作为新一代的航空电子系统通信网络技术,具有传输速度高、延时低、传输距离远和可靠性高等特性,高达4G bps的数据传输带宽,为其上层通信协议提供了一种通用的高速率的数据传输通道。FC-1553作为光纤通道上层通信协议之一,对MIL-STD-1553通信协议具有完全的兼容性,它继承了传统MIL-STD-1553通信协议的基本特征,实现了向光纤通道链路层的映射,从而扩展了通信网络的结构,提高了网络的通信能力。本文首先介绍MIL-STD-1553和光纤通道的基本特性,然后描述在光纤通道中对1553通信协议的映射,最后,提出了基于光纤通道和MIL-STD-1553的航空电子系统通信网络结构。
Fibre channel, as one of the candidates for the next generation avionics system networks, has features, such as high transmission rate, low time delay, long transmission distance, and high reliability. It provides a high-rate data transmission channel to high-level communication protocols. Its highest bit rate can be up to 4Gbps. FC-1553, a fiber channel protocol, is compatible with MIL-STD -1553, and, by inheriting the basic characteristics of MIL-STD-1553 based systems, implements the map of MIL-STD-1553 on fibre channels. So the scale of the networks will be expanded in structure and data transmission. This paper, first of all, presents MIL-STD-1553 and the basic characteristics of fiber channel, and then describes the data frame mapping from MIL-STD-1553 to fiber channel. Finally, an application of fiber channel network, which is based on legacy MIL-STD-1553 systems, is given.
