基于FPGA和USB接口的超声波信号高速采集卡
High speed ultrasonic signal acquisition card based on FPGA and USB interface
摘要
Abstract
An AD acquisition card with a sampling rate up to 100 MS/s is needed in the ultrasonic rail flaw detection system, so the high speed ultrasonic signal acquisition card based on FPGA and USB interface is designed. FPGA-based hardware design and programming method, firmware and driver design based on CY7C68013 USB 2.0 chip are introduced in detail. Analog signal acquisition frequency up to 100 MHz, the maximum data transfer rate of 20 MB/s, the acquisition card can acquire ultrasonic signals in real-time without missing data.关键词
