Road, ethernet interface circuit, serial line interface and power supply；The FPGA drives with the Camera Link interface chip, VGA respectively
Dynamic circuit, DDR3, serial port module, FPGA clock, SATA interface, SATA link, FPGA configuration circuit, ethernet interface circuit connect
It connects；Serial line interface described in the too network interface circuit connection.
According to an aspect of the present invention, serial line interface is RJ45 interface.
According to an aspect of the present invention, power supply provides 1.2V, 1.5V, 2.5V, 3.3V, 5V voltage.
According to an aspect of the present invention, Camera Link interface chip includes: data receiver chip, camera control core
Piece and serial communication chip.
Working principle: system selects the GZL-CL-41C6 model of Point Grey company production to tell gray scale camera, passes through
Camera Link interface chip sends image data and synchronization signal, and serial ports receives camera control commands, and image resolution ratio is
2048 × 2048 pixels, frame frequency 150f/s, pixel format 8bit.Since the data volume that camera generates is about 600MB/S, two
The writing speed of the monolithic solid state hard disk of SATA interface is about 180MB/S, so constituting RAID0 array using 4 pieces of solid-state hardboards
It is stored.The high speed image data of system acquisition industrial camera output, and it is divided into two-way after transmitting data to FPGA, all the way
It is parallel to be stored in solid state hard disk permutation after DDR3 is cached；Another way is stored in DDR3 caching after format is converted, then
Pass through USB interface real-time display image data.
System of the invention can deposit the high speed image that resolution ratio is 2048 × 2048 pixels, frame frequency is 150f/s
Storage and real-time display, portable and practical value with higher.
The present invention is not limited to examples detailed above, in claims of the present invention limited range, art technology
The various deformations or amendments that personnel can make without creative work are protected by this patent.
