[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.
