Abstract

In view of the low leakage detection rate of tailings pipeline, a method of tailing pipeline leakage detection based on multisensor and multi-entropy fusion was proposed. Firstly, the parameters of VMD algorithm were optimized by Sparrow Search Algorithm. The signal is decomposed by an optimized VMD algorithm, and the decomposed modal components are screened and reconstructed by kurtosis analysis. After that, the leakage experiment platform is built, the signal is collected by infrasound and negative pressure wave sensors, and the singular spectrum entropy and sample entropy of the pipeline signal are calculated, and the threshold interval of the two are obtained as the basis for judgment. Leakage experiments show that this method can accurately judge the leakage signal, and compared with the single sensor and single entropy fusion method, the accuracy is significantly improved.
