中文摘要:
      为了实现机载网络环境下基于高速航电总线的多路DVI视频信号的测试抽引难题,提出了机载多路DVI视频信号分配器的设计方案。针对高速航电总线多路DVI视频信号速率高、实时性强、路数多的特点,完成了高速航电总线视频信号转换模块、高速信号分路模块等电路设计,实现了千兆网络视频信号的采集处理及分路转发功能。实验结果表明,该机载高速总线视频分配器在不影响原机视频链路的情况下,解决了高速航电总线多路DVI视频信号的分路抽引需求。
英文摘要:
      In order to realize the test of multi channel DVI video signal based on high speed avionics bus, the design scheme of airborne multi channel DVI video signal distributor is proposed. According to the characteristics of electric bus multi channel DVI video signal rate high speed, real time and multiway, complete video signal conversion module, signal shunt module circuit design, realize data acquisition processing and shunt gigabit network video signal transmitting function. The experimental results show that the airborne high speed bus Video Splitter without affecting the original video link condition, solve the high speed shunt avionics bus multi channel DVI video signal drawing requirements.
