Focusing on the shortage of low detection precision of the traditional pipeline magnetic-flux leakage detector

a new system design of high precision detector inside of pipeline based on FPGA is presented to fit in the 813 mm pipe detecting task.The logical design of the system is mainly introduced

as many as 400 channels sensor signal acquisition and storage are achieved.The design integrates multiple bus protocols to solve the problems of acquisition rate

power consumption and precision in the magnetic-flux leakage detecting area.It’s verified that the scheme is a pratical design

and it provides a new solution for the design of high-precision magnetic-flux leakage detecting system inside of pipeline.
