Method, device and equipment for detecting micro-damage through far-field eddy current and storage medium

The invention relates to a method, a device and equipment for detecting micro-damage by far-field eddy current and a storage medium. The method comprises the following steps: determining a target detection frequency according to detection sensitivity and penetration depth; extracting experimental data, wherein the experimental data include the corrosion size, the corrosion depth, the crack depth and the crack length; manufacturing standard detection test blocks according to the experimental data, wherein the standard detection test blocks comprise a multi-layer structure inner layer crack defect detection test block, a multi-layer structure inner layer corrosion defect detection test block and a multi-layer structure rivet hole fatigue crack detection test block; carrying out micro-damagedetection on each corresponding standard detection test block according to the target detection frequency by applying a far-field eddy current detection technology so as to determine the damage type and the damage position of
