摘要
伴随航空技术的飞速发展,传统数字视频接口DVI电信号传输方式已无法满足复杂航空电子环境下高速、高可靠、远距离图像传输要求。面向新一代航电系统中图像传输设计需求,提出基于光纤通道的DVI信号远程传输系统架构及相关实现技术,结合FC协议及视频标准制定了基于光纤域的图像映射方法,说明了收发端口各功能单元的设计要素并对信号收发处理进行了阐述,构建了基于光纤通道的DVI信号传输系统。测试和验证结果表明图像传输与显示满足设计要求,为DVI信号基于光纤通道的实时转换与远距离传输提供了解决方案。
With the rapid development of aviation technology,the traditional DVI electric signal transmission mode can no longer meet the requirements of high speed,high reliable and long distance image transmission in complex avionics environment.Faced on the requirement of image transmission design in the new generation of avionics system,provide a system structure and correlative technology based on DVI signals long distance transmission in fibre channel(FC),define the method for image mapping in FC area based on the FC protocol and video standard,explain the design element of function cell in DVI receiver and transmitter port,expatiate the signal receiving and transmitting process,a FC based DVI signal transmission system is constructed,the testing and verification results show that image transmission and display meet the design requirements.It puts forward a solution of DVI signal real time transform and long distance transmission based on the fibre channel.
