PORTABLE AUTOMATIC SUPERSONIC PROBE USING MULTI-AXIS PORTABLE SCANNER

摘要

The present invention relates to a simple automatic ultrasonic flaw detector using a multi-axis portable scanner. In the related art, it is very difficult to secure reliability because it depends on the manual operation of the operator, but the apparatus of the present invention has a six-axis portable scanner to have six different independent directions of movement so as to accurately detect the position of the ultrasonic probe 33. When the ultrasonic probe 33 employing the 100 is placed at a predetermined position of the structure to be inspected, the ultrasonic wave scanned by the ultrasonic probe 33 is processed and the diffraction angle of each axis of the flaw detector is processed. Various position sensors and interfaces that detect and process inspection positions, and fault and position signal analysis software installed in the main memory of the computer use the encoder counter value and the fault data digital data inputted into the main memory of the PC through the signal processing device. The position of the ultrasonic probe 33 is a static kinematic system of the portable scanner 100 using the count value of the encoder counter. This can be determined by performing the calculation, and the relative position with respect to the test object is obtained through coordinate transformation, so that the defect position can be constructed by linking the previously obtained defect position with the scanning motion of the ultrasonic probe. The type of defect can be determined by using the ultrasonic shape recognition technique and neural network technique properly. By utilizing the system of the present invention, it is expected to significantly improve the reliability of the ultrasonic flaw test and increase the reliability of the safety analysis and the life evaluation of the large structure based on this.
