The present invention discloses a pipeline leakage monitoring and
early warning system, which belongs to the technical field of pipeline network leakage monitoring. The present invention calculates the number of sampling points by the collected audio sampling rate and the
collection time. N , the
signal is calculated by the
feature recognition algorithm level Values,
Fourier transform coefficients, center of gravity frequencies and pipeline leakage characteristic values are generated. At the same time,
time domain waveforms, spectrograms, and time-frequency graph data are generated. Through matching and comparison analysis of pipeline leakage characteristic values, associated data, and altitude location case libraries, characteristic parameter case libraries, leakage audio case libraries, and
noise audio case libraries, it is accurately determined whether there is a pipeline leak. By continuously updating the altitude location case
library, characteristic parameter case
library, leakage audio case
library, and
noise audio case library, a pipeline leakage
signal early warning model that can be used for different temperatures, different altitudes, different regions, equipment voltages, temperatures, and environmental conditions is established. The leakage
signal early warning model is updated, which can significantly improve the early warning accuracy of pipeline leakage monitoring.
