摘要
随着航空电子技术的发展,现在的航电主网络MIL-STD-1553B,其1Mbps带宽越来越不能满足高速数据交换的需求,以光纤通道来替代现有的航电网络成为重要的发展趋势,为实现系统的平稳升级,需要兼容传统的1553B设备;重点介绍了光纤通道与MIL-STD-1553B桥接的主要技术,并且给出了光纤通道兼容MIL-STD-1553B设备的软硬件设计方案,搭建了基于FPGA+HOLT1575的软硬件平台,验证了桥接设计方案的正确性与可行性,为MIL-STD-1553B总线到高速光纤网络的过度提供了设计参考。
With the development of avionics, MIL--STD--1553B cannot meet the requirement of high--speed data exchange because of the low bandwidth of 1Mbps. The trend of fiber--optic network replacing existing avionics network is certain, so it is necessary to enable the leveraging of MIL--STD--1553 system in the smooth upgrading of avionics. Bridging technology between fiber channel and MIL--STD-- 1553B is introduced in detail, and designing scheme of bridge including software and hardware has been put forward. Finally, its feasibility is validated through constructing software and hardware system based on FPGA and HOLT1575, which can provide an implementation guide for upgrading data bus.
