Paper Abstract

This paper proposes a portable ultrasonic guided wave detector based on ADLINK COM Express (Computer On Module Express) computer module. This detector is equipped with Windows7 operating system and uses the PCIe (Peripheral Component Interconnect Express) bus as the FPGA (Field Programmable Gate Array) of COM Express and Xilinx. The data transmission rate can reach 500MB/s in the transmission line. In addition, a self-developed high-voltage pulse signal generation circuit and signal acquisition circuit are used in the analog circuit. Finally, this developed detector is used to excite ultrasonic guided waves in the aluminum plate and the pipe to realize the identification of defect echo signals in these two structures, which verify the reliability of the designed detector.
