摘要

针对舰载光电侦察设备中业务数据到指控席间传输距离远, 易受干扰等问题和保密性要求, 设计了一种基于赛灵思 Aritx-7系列 FPGA的 GTP收发器的光纤传输系统。实现了 1路 HD-SDI接口可见光高清视频、1路 CameraLink接口红外视频和 1路 RS422接口光电操控指令数据通过一根光纤传输。发送部分设计了状态机, 通过分时复用, 实现并行数据转串行发送; 接收部分, 利用 DDR3和 FIFO缓存, 实现了业务数据从光纤通道到原视频接口和 RS422接口的还原。实验结果表明, 该传输系统可以满足视频和操控指令信息的远距离传输, 视频清晰, 操控灵敏。对其他业务数据的传输具备一定的参考价值。

Abstract

For shipboard electro-optical reconnaissance equipment，lots of problem exist，such as business data to the charges at the transmission distance，complex electromagnetic environment and confidentiality requirements. A kind of optical fiber transmission system based on the GTP transceiver made of Xilinx Aritx-7 series FPGA is designed in this paper. It is implemented that 1 channel visible light high definition video of the HD-SDI interface，1 channel infrared video of camera link interface and 1 channel RS422 interface data through a single fiber. In the sending part，the parallel business data is converted to serial data and transferred by the design of the state machine and the use of time-sharing multiplexing. In the receiving part，using the DDR3 and FIFO buffer，the business data from the optical fiber channel to the reduction of the original video interface and RS422 interface is implemented. The experimental results show that the transmission system can satisfy the remote transmission of video and control command information，the video is clear，the manipulation is smooth and easy. For other business data transmission，this design still has the certain reference value.
