| Abstract: | This paper puts forward three leakage detection methods of the piping system based on the knowledge.The first is the diagnosis system which symbolizes the negative wave form in segment mode and uses the contextfree grammar of symbolic representation of the wave form to identify the mode.The second is the neural network detection system which uses a neural network with the input matrix composed by stress wave characteristics in time domain or frequency domain to classify various situations of the pipeline.And the last is the leakage diagnosis expert system which combines the leakage mechanism mathematics model. |

| Keywords: | leakage of pipeline pattern recognition neural network expert system |
