• Abstract:

  Due to the presence of various noises and interferences, the spectral trajectory extraction method cannot accurately locate the weak signal spectral trajectory information under transient conditions.In addition, the repeated superposition between multi frequency band signals results in low completeness of the extracted trajectory and significant deviation of the corresponding trajectory information, which cannot meet the requirements of practical application analysis.Therefore, a method is proposed to introduce fusion filtering algorithm and propose a multi frequency non repetitive transient weak signal spectral trajectory extraction method for industrial control networks.Build a Qgbost strong classifier for multi band signal states in industrial control networks, and clarify the current non repetitive transient weak signal states in multi band industrial control networks.Based on the classifier results, the fusion Bloom filter is used to remove duplicate signals from the multi frequency transient weak signal sequence in the industrial control network after classification.In order to further avoid the influence of noise and other factors, a fusion filtering algorithm is used to filter the multi band weak signal spectral trajectories of the input industrial control network, in order to restore the original signal.The multi band non repetitive transient weak signal spectral trajectories are extracted through average sampling processing, reducing the effect of extraction bias.The comparison of experimental data shows that the proposed method can better extract weak signal spectral trajectory information under transient conditions, and the extraction effect is more stable and reliable.
