Abnormality detection method, device and equipment for connecting part, medium and program product

The invention discloses an anomaly detection method, device and equipment of a connecting part, a medium and a program product, the connecting part comprises a first conductor and a second conductor, the first surface of the first conductor is in contact with the second surface of the second conductor, and the first conductor, the second conductor and an alternating current source are connected in series to form a test loop; the anomaly detection method comprises the following steps: when the frequency output by an alternating current source changes from a first frequency to a second frequency, determining a first voltage and a first current obtained under a plurality of frequencies between the first frequency and the second frequency; according to the first voltage and the first current obtained under the multiple frequencies, resistance calculation values corresponding to the multiple frequencies are determined; according to the resistance calculation values corresponding to the plurality of frequencies, determining a corresponding target frequency when the resistance calculation values suddenly change; determining the thickness of a film layer between the first surface and the second surface according to the target frequency; and according to the film layer thickness, determining whether the connection part has connection abnormity. Therefore, the anomaly detection accuracy of the connecting part is improved.
