Aiming at particularity of steel pipe magnetic flux leakage detection

a flaw detection system with interference filtering is designed and developed

signal receiving module with multi-serial port card is used for opening up multiple memory buffers

data can be analyzed and processes by multi-threads

the speed of data processing and instantaneity of detection are greatly improved. In this system

the magnetic flux leakage detection signal is processed by the method of mean-shift wavelet threshold denoising which can effectively reduce effect of measurement noise and eliminate the pseudo Gibbs phenomenon. The software of this system is implemented by Visual Studio C #

and unattended detection and control of automatic pipeline

steel pipe defect determination

alarm and analysis and processing can be achieved. Compared with traditional magnetic flux leakage testing monitoring software

the system has higher availability and reliability.
