未来航空电子高速数据总线技术的研究

A preliminary study on high-speed data bus of future avionics

高速数据总线技术是航空电子综合化最重要的支撑技术之一 ,直接决定整机航电系统综合化程度的高低。本文结合美军 JAST计划 ,分析了高速数据总线技术的若干问题 ,针对JAST计划中统一网络的首选协议 SCI做了实际的网络性能测试 。

High speed data bus technology is one of the key technologies in avionics integration, which has direct influence on the performance of the avionics system of tactical aircraft. Several issues of high speed data bus have been discussed in this paper with JAST as the background. Experiment on SCI, the primary candidate of the Unified Network of JAST, has been performed and the result is presented.
