摘　　要：针对工业在线图像采集与传输设计千兆网络传输采集卡,采集卡采用DSP加FPGA架构搭建,实现Cameralink相机接口图像采集与预处理功能,并通过光电隔离读取控制信号对在线产品队列实现信息记录功能。主要讨论DSP与千兆PHY芯片的RGMII模式硬件接口设计及DSP端千兆网络驱动设计。通过多种不同大小数据包发送方式测试千兆网络性能。结论显示本采集卡的千兆网络传输具有较高的传输效率,符合工业实时在线采集传输功能要求。Aiming at industrial on line image capture and transmission,a capture card is designed with gigabit ethenet transimission function. The capture card is composed with DSP and FPGA,implementing image capture with cameralink interface and image preprocessing. The capture card recording products information with control signal send by Photoelectric isolation device. The development of the hardware circuit design about DSP and gigabit PHY interface in RGMII mode,and the procedure of DSP ethenet driver design are disscussed. When data is transmitted at full wire rate,sending diffrient packages,testing CPU load and transimiting rate. The conclusion indicates that the capture card has efficient,and independent,coincidenting real-time industrial on line capture and transmission requirement.
