“…The features of USB can benefits to ultrasonic detecting instruments for its high speed and dynamic attachment and removal [7]. In this system we choose a powerful EZ-USB FX2 chip CY7C68013 provided by Cypress Company, it packs all the intelligence required by a USB peripheral interface into a compact integrated circuit, which will finish most of the communication work for the user, so there is no need for the user to know the lower USB protocol.…”

In order to meet the need of high speed data transfer in ultrasonic inspection nowadays, a PC and USB based high speed digital ultrasonic flaw detector is introduce. The technology of USB (Universal Serial Bus), especially USB2. 0 facilitates the connection ofPC to peripheral, and accelerates data transfer. By using the USB interface the speed of data transfer is significantly increased, which solved the real-time problem. At the same time, the PC can control the testing process, analyse the echo signal, and realize automatic testing. The use of FPGA (Field-Programmable Gate Array) decreases the volume of the circuit, improves the speed of data sampling and processing, increases the reliability, shortens the developing time, and at the same time makes modifications made to the system easier. In this paper a digital ultrasonic flaw detector specialize in inspecting rail weld, based on PC, using USB2. 0 and FPGA technique is presented The design of FPGA and the use of GPIF (General Programming Interface) USB transfer mode are introduced in detail.
