Intelligent detection device based on pulsed eddy current

The invention discloses an intelligent detection device based on pulsed eddy current, which comprises a combined array type probe (1), an intelligent control module (2), an excitation source (3), a signal processing module (4), a power supply module (5) and a virtual instrument (6), and is characterized in that the intelligent control module (2) is connected with the virtual instrument (6) and controls the combined array type probe (1) and the excitation source (3) simultaneously. The technical effects of the invention are as follows: 1) the combined array type probe is adopted to enlarge thedetection range of the detection device and improve the detection precision; 2) the frequency of the excitation source, the coil probe and the distance between the probe and the detected surface are automatically selected by adopting the intelligent control module, so that the frequency of the excitation source is optimally matched with the coil probe, and the detection precision can be further improved; and 3) an intelligent control module is adopted, so that the detection device can automatically realize high-precision detection, and human errors are reduced to the maximum extent.
