In order to improve the diagnostic capability of gas pipeline leakage failure and predict the risk of gas pipeline fault leakage,the depth learning neural network is applied in the field of gas pipeline fault diagnosis,and a gas pipeline fault diagnosis technology based on convolution neural network and softmax classifier is proposed.The nine characteristic parameters in the gas pipeline failure are selected as the original input of the model,and the feature extraction,parameter reconstruction and softmax classification of the convolution neural network are used to achieve the effect of diagnosis.The obtained convolution cloud neural network model is applied in the laboratory fault detection system of gas pipeline fault and the results show that the accuracy of this model is 92.54%in the gas pipeline fault identification,and the method has obvious accuracy and stability compared with other methods such as BP.
