Because of the problems that low location positioning accuracy and more number of iterations of traditional artificial intelligence algorithms that applied to detect the gas leakage. This paper proposes a distribution estimation algorithm based on…
As negative pressure wave is applied to leak detection and location of natural gas pipeline, the key is how to realize accurate measurement of propagation velocity of pressure wave and time difference. However, there exists problem of lower accuracy…
This paper analyzes the properties of wavelet transform and its potential application in detecting the leakage location of gas pipeline. An entity-part method, which is proposed for the accurate leaking point, has been proved valid in the stimulation…
Leak detection of gas pipelines has attracted extensive attention in recent years because such a leak could result in significant damage to society. This paper proposes an integrated leak detection method using acoustic signals based on wavelet…
