【摘要】：針對遠距離傳輸必須滿足頻帶寬、抗干擾能力強等特點,實現一種直接光纖高分辨率、高幀率遠傳監(jiān)控攝像機的數據傳輸設計。采用FPGA為主控器設計的PCI Express光纖接口卡,實現了監(jiān)控攝像機與計算機之間的大量數據的實時遠程傳輸。采用Windows DDK開發(fā)工具開發(fā)了高效率的WDM驅動程序,實現光纖接口卡在Windows XP系統(tǒng)環(huán)境中能夠穩(wěn)定、可靠地工作。驅動程序以直接存儲器訪問的傳輸方式將大量數據從光纖接口卡發(fā)送到計算機內的指定內存空間,完成驅動程序與應用程序以及光纖接口卡之間指令數據的傳輸,設計了中斷響應程序,確保實時地處理接收到的數據。
[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.
