摘要
随着航空电子系统的发展,ARINC 818成为新一代航空视频传输总线协议标准。针对此标准设计了一种机载高速视频切换系统。介绍了ARINC 818的航空视频传输总线协议标准,根据该标准对机载高速视频切换系统设计原理进行了阐述,并详细介绍了每个系统组成部分的设计方案。最后,搭建硬件测试平台进行测试和验证。系统开发遵循集成化、模块化的设计,以现场可编程门阵列(FPGA)以及高速交叉开关协议芯片为核心,设计实现了分辨率为1920×1080@60 Hz,4.25 Gibit/s链路速率的8路ARINC 818视频输入、24路ARINC 818视频输出的高速视频实时切换输出显示系统。该设计方案已在多个型号中成熟应用,具有重要的实际应用价值。
With the development of the avionic system,ARINC 818 has become a new generation aviation video transmission bus protocol standard.Aiming at this standard,an airborne high-speed video switching system was designed.This paper introduces the aerial video transmission bus protocol standard of ARINC 818,expounds the design principle of airborne high-speed video switching system based on the standard,and introduces the design scheme of each system component in detail.A hardware test platform was built up for testing and verification.The development of the system adopted integrated and modular design.With Field Programmable Gate Array(FPGA)and high-speed crossover protocol chip as the core,a high-speed,real-time video switching output display with 8-channel ARINC 818 video input and 24-channel ARINC 818 video output,a resolution of 1920×1080@60 Hz and a link rate of 4.25 Gibit/s was designed.The design scheme has been successfully applied to multiple types of aircraft,and has important practical application value.
