Abstract Natural gas pipelines are an essential part of the economy. may leak after aging, strong vibration signals be generated in pipeline when leakage occurs, and noisy. Traditional variational mode decomposition (VMD) noise reduction methods need to set parameters advance, so not achieve best effect. To solve this problem, paper proposes a method for location based on sparrow search algorithm (SSA) optimization VMD combined with generalized quadratic cross-correlation. The first calculates original signal-to-noise ratio (SNR), if SNR is low, wavelet threshold denoising used process signal. Then, SSA refine two key (penalty parameter α number K ) sample entropy. Subsequently, signal undergoes into intrinsic function (IMF) components through according obtained analysis combination. IMF screened obtain reconstructed Finally, obtained. delay cross-correlation accurate position using delay. Experiments showed that minimum relative error could reach 0.6%, which was more than traditional method, effectively improved accuracy noisy locations.
