| description | The invention relates to the field of data processing, in particular to an automobile cooling fin working condition monitoring method, which comprises the following steps: acquiring a vibration data sequence and a noise data sequence, calculating an abnormal factor of any vibration data in the vibration data sequence, and calculating the filtering degree of each vibration data by integrating a reference data segment, and according to a comparison result of the filtering degree of each piece of vibration data and a preset threshold value, adaptively adjusting the frequency of de-noising processing on each piece of vibration data, and performing anomaly detection on the de-noised vibration data sequence so as to monitor the working condition of the automobile cooling fin based on an anomaly detection result. According to the invention, the frequency of denoising processing on each vibration data can be adaptively adjusted, the phenomena of excessive smoothness and insufficient smoothness during denoising of the |
