Abstract: The waveform of dynamic pressure wave contains the safety information of
petroleum pipeline. The complete automatic identification program for the leakage signal of
petroleum pipeline was proposed based on the characteristics of the dynamic pressure wave
signal from the point of view of the signal processing. Wavelet and empirical mode
decomposition method were adopted to deny the signals collected by dynamic pressure
transmitter respectively. We tried to use the statistical characteristics of the one-dimensional
digital sequence to describe the signal. Support vector machine method which is suitable to small
size sample was selected to automatically identify the leaked signal of petroleum pipeline. And a
relatively high signal identification rate was acquired. © 2013 IFSA.
