High-Speed Video Signals Fiber Transmission Design Based on FPGA

本文针对数字化光电经纬仪需要将主摄影系统设备产生的500帧/秒,30Mbyt/s×20路的数字视频信号传输到主控计算机的具体要求,提出基于FPGA以及HDMP-1032/HDMP-1034的高速视频信息光纤传输系统设计方案。系统设计主要包括数字信号的复用/解复用,高速并/串信息转换,光纤旋转连接器等部分,应用了FPGA编程、CIMT信道编码以及高频电路PCB设计等技术实现了数字化光电经纬仪中高速视频信息的无误传输,改善了高速视频信息的传输质量。

To transmit the 500 frame/s, 30 Mbyt/s X 20 routes digital signals from the vlaeo system to the main control computer system of the digital optical-electronic theodolite. This paper carries out a highspeed video signal fiber transmitting design scheme based on FPGA and HDMP-1032/HDMP-1034. The system design mainly includes the digital-multiplexing/de-multiplexing, the transition between parallel signals and serial signals and fiber optical rotary joint. Otherwise the design uses the FPGA programming, CIMT channel coding and high-speed circuit PCB technology to realize the correct transmission of the highspeed video signals of the digital optical-electronic theodolite.
