Aiming at the defect of weak stability, poor real-time performance and low efficiency of traditional alternat-ingcurrent field measurement （ACFM） system,We design a new ACFM nondestructive testing prototype based on NI-USB-6210 data acquisition card from the engineering application. The hardware system design of the prototype is introduced, and the software of ACFM nondestructive testing system is explained briefly. The hardware system mainly includes sinusoidal signal excitation, power amplifier integrated circuit, sensor detection module, signal conditioning circuit and data acquisition module. The experimental results and filed test prove that the prototype has the advantages of fast real-time performance, good stability, sturdy reliability, high detection efficiency and a good human-computer interaction interface in nondestructive testing.
