【摘要】：针对远距离传输必须满足频带宽、抗干扰能力强等特点,实现一种直接光纤高分辨率、高帧率远传监控摄像机的数据传输设计。采用FPGA为主控器设计的PCI Express光纤接口卡,实现了监控摄像机与计算机之间的大量数据的实时远程传输。采用Windows DDK开发工具开发了高效率的WDM驱动程序,实现光纤接口卡在Windows XP系统环境中能够稳定、可靠地工作。驱动程序以直接存储器访问的传输方式将大量数据从光纤接口卡发送到计算机内的指定内存空间,完成驱动程序与应用程序以及光纤接口卡之间指令数据的传输,设计了中断响应程序,确保实时地处理接收到的数据。
[Abstract]:In view of the fact that the long distance transmission must meet the characteristics of wide frequency band and strong anti-interference ability, the data transmission design of a direct optical fiber high resolution and high frame rate remote transmission monitoring camera is realized. The PCI Express optical fiber interface card designed by FPGA as the main controller realizes the real-time remote transmission of a large number of data between the monitoring camera and the computer. An efficient WDM driver is developed by using Windows DDK development tool to realize that the optical interface card can work stably and reliably in Windows XP system environment. The driver transmits a large number of data from the optical interface card to the specified memory space in the computer by means of direct memory access, completes the transmission of instruction data between the driver and the application program, as well as the optical fiber interface card, designs the interrupt response program, and ensures the real-time processing of the received data.
