摘要
Abstract
This paper investigates a water pipeline leakage detection method based on an accelerometer.Sensors are ar-ranged at different positions above and around the leakage point of the pipeline to directly collect the acoustic signals from the ground surface and perform spectral analysis to identify and quantify leakage characteristics.Experiments show that the leakage signal attenuates with increasing propagation distance and experiences a small frequency shift(about 200 Hz)when passing through different ground materials.Different ground mate-rials have different sound propagation rates for leakage signals(asphalt＞concrete pavement,sidewalk slabs＞green grassland),and the leakage signal has a greater propagation capability along the pipeline direc-tion than in directions deviating from the pipeline.This method can effectively capture and analyze leakage sig-nals under complex ground conditions and simplifies the traditional leakage detection process.关键词
