| Abstract: | In the paper, magnetic flux leakage(MFL) on-line testing system for steel tube is introduced. The designing method for the main hardware , like convection device for steel tube, detecting devices along the longitudinal axis and circumference , is described. The multichannel data acquisition based on the signal modulation-demodulation pattern at a high speed is designed. The software based on multi-thread and VXD techniques includes data acquisition ,status display, real-time control ,system verifying and so on . Practical applying shows that the system is effective. |
