Design of a Portable Frame Integrality Testing System Based on SOPC

As there is no technology to detect the frame number area hidden weld rapidly and accurately, the frame integrality detection algorithm was studied in this paper. First of all, to achieve the conversion of longitudinal wave to transvers wave, the waveform transformation technology was applied to multiple thin and high impedance materials. The acoustic wedge was designed by using Plexiglas through 30 degree incident angle. Ultrasonic receiving and launch, signal acquisition and processing, display and alarm device were integrated using upper and lower structure based on the SOPC system of Niso II. This method showed that the instrument can accomplish the integrity of the frame detection rapidly, efficiently and accurately.
