FC-AE-1553数据总线的特点及在航天领域的应用

MIL-STD-1553B总线被广泛运用于许多嵌入式系统,例如飞机、轮船、导弹、卫星等。但是随着科学技术的发展,当前的航空航天系统,武器系统的互连子系统的数量和复杂性不断增加,系统对高带宽、低延时数据需求愈发迫切,而光纤天然具有的高带宽、低延时的特点能够很好解决上述需求。除此之外,用光纤搭建的通信网络还具有灵活的拓扑结构、较远的传输距离、高抗电磁干扰等优点。FC-AE-1553的通信介质采用光纤,其各个节点之间的通信协议与MIL-STD-1553B高度相似,因此采用FC-AE-1553通信协议的新设备能够较好地兼容MIL-STD-1553B协议的传统设备。

The Characteristics of FC-AE-1553 Data Bus and Its Application in Aerospace Field

The MIL-STD-1553B bus is widely used in many embedded systems, such as aircraft, ships, missiles, satellites etc. However, with the development of science and technology, the number of the current aerospace system''s interconnection subsystems is increasing, and the needs for high bandwidth and low latency data become more urgent. The features of optical fiber are high bandwidth and low delay, so it can be a good solution to the above demand. In addition, the communication network built by optical fiber also has the advantages of flexible topology, longer transmission distance, high anti-electromagnetic interference and so on. FC-AE-1553 uses optical fiber as its transmission medium, and the communication protocol between each node is highly similar to MIL-STD-1553B. Therefore, using the new equipment of FC-AE-1553 can be more compatible with MIL-STS-1553B communication network.
