Research of a High-Speed X-Ray Nondestructive Detector Based on FPGA

摘要：

A high-speed X-ray nondestructive detector based on FPGA is researched in this paper. The principle of Xray nondestructive detection is analyzed, and a general system scheme of the high-speed X-ray nondestructive detector is proposed. The Virtex-4 series Fx12 FPGA chip is used to design detectors hardware circuit, the PowerPC405 embedded system is developed, the high-speed image processing algorithM is applied to compile its processing software, and the TCP/IP protocol is employed to compile the correspondence software, to realize high-speed X-ray signal gathering, processing and the transmission. The experimental result indicated that the running rate of the conveyer belt could achieve 4m/s when the survey width of the detector is 1.6m. The detector can be applied to the long-distance and on-line nondestructive detection of product line with Steel Wire Ropes in correlative industry field, such as mines, ports and wharfs, etc.
