Tailing pipeline leakage detection system

The invention relates to the technical field of tailing pipeline leakage detection, in particular to a tailing pipeline leakage detection system which comprises a tailing pipeline, and a noise filtering mechanism is embedded in the outer wall of the tailing pipeline and electrically connected with a collection station. According to the tailing pipeline leakage detection system, the influence of slurry pump operation on the pipeline can be eliminated through the integrated FIR band-pass filtering module and the self-correlation and power spectrum analysis module, and then noise is eliminated through FIR band-pass filtering, so that the influence on the detection effect is avoided; a threshold curve and the filtered operation data are fitted through a leakage self-sensing module, a threshold iteration self-adaption module and a sensor historical data module, whether the operation data is in a reasonable interval or not, whether a leakage trend exists or whether leakage occurs or not is judged in real time, leak
