Non-metal water supply pipeline leakage position positioning system considering influence of soil body

The invention discloses a non-metal water supply pipeline leakage position positioning system considering the influence of a soil body. The system comprises a vibration sensor configured to be used for synchronously collecting vibration signals of an exposed measuring point and a simulated water leakage port; a wave number prediction model is arranged in the wave number prediction module, and the wave number prediction module is used for inputting the frequency of each target sound wave and buried soil parameters and outputting the comprehensive wave number of each target sound wave; the signal preprocessing module is configured to obtain an actually measured complex wave number, a characteristic frequency band and a corresponding time delay parameter; the buried soil body parameter acquisition module is configured to calculate buried soil body parameters of the simulation pipe section according to the actually measured complex wave number; the frequency division speed acquisition module is configured to calc
