With the development of avionics and the improvement of integration technology, MIL-STD-I553 bus's transmission velocity, bandwidth, quantity of allowed terminals and real-time ability have appeared inadequate. Therefore, FC-AE-1553 bus was introduced to overcome the bottleneck caused by MIL-STD-1553. In comparison with the network structure and message configurations of MIL-STD-1553, it is found that FC-AE-1553 bus is much better than MIL-STD-1553 bus in the aspect of performance. The data processing method of FC-AE-1553 is proposed in combination with MIL-STD-1553 bus data processing experience.%随着航空电子技术的发展及综合化程度的提高,MIL-STD-1553总线在传输速率、带宽、允许终端数、实时性等方面开始显得力不从心,为了解决MIL-STD-1553所面临的瓶颈问题,引入FC-AE-1553总线并与MIL-STD-1553比较网络结构与信息构成,经比较得出FC-AE-1553在性能上比MIL-STD-1553更优.结合MIL-STD-1553总线数据处理的工程经验提出FC-AE-1553协议的数据处理方法.
