Localization system for leakage points in mine drainage pipelines

In response to the problems of high leakage rate, untimely detection, and high maintenance cost in mine drainage pipelines, a mine drainage pipeline leakage location system was designed based on the acoustic detection method. The position of the leakage point was calculated through cross correlation algorithm based on the time difference of the sound signal, which can effectively reduce the maintenance cost of the mine drainage pipeline, timely detect pipeline leakage, and achieve accurate positioning of the leakage point, reducing disaster risk. The mine drainage pipeline leak location system designed in this article integrates acquisition probes and digital filters, adopts cross correlation analysis algorithms, and provides online leak location services. Tests have shown that the drainage pipeline leakage location system can accurately locate pipeline leakage points in different scenarios.
