摘　　要：开发了一款基于C#的数据传输处理显示的上位机软件和硬件控制的FPGA(Field Programmable Gate Array,现场可编程门阵列)下位机为一体的多媒体数据传输系统,对于水下光通信整体系统的水下工程应用具有一定价值。上位机与下位机之间通过千兆以太网进行交互,整个系统具有传输速率可变的多媒体数据传输模式与光信道性能检测模式。在光信道的误码率为0时可收发完整文本、图片及视频、调用摄像头定时拍照、定时间隔拍照、循环收发图片等数据。经实验证明,该多媒体数据传输系统能够满足实际使用需求,丢包率近乎为0,具有良好的稳定性、实用性和互动性。A subsystem consisting of computer,FPGA and related software is developed for underwater wireless optical communications for the convenience of interactivity and observation of transmission rate.The computer is served as the master,processing images and video with a software developed by C#,and FPGA works as the slave,directly control ling the data transfer rate and driving the subsequent devices.The computer and FPGA can communicate via gigabit ethernet with an adaptive rate to send or receive files such as text,image and video stored in,or acquired from a camera,which can be activated by the master to work periodically.Experiments show that the system can meet the need of actual use with a zero packet loss rate,and has good stability,practicability and interactivity.
