The alternating current magnetic field(ACFM)detection test bench is used to verify the principle of the ACFM detection technology,optimize the design of offshore platform ACFM detection system and explore the failure quantitative evaluation.The test bench consists of function generator,power amplifier,testing probe,data collector,typical failure sample,electric translational platform,stepping motor driver,PLC and computer.The motion control of detection scanning has been achieved through serial communication function and PLC serial communication in the LabVIEW development environment.The data collection control has been achieved through the DAQ assistant.Adoption of the producer-consumer mode achieves the synchronous control of scanning motion monitoring and data collection,which provides the convenience for ACFM detection test.
