Embodiment Construction
[0015] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0016] 1. a pipeline leak detection method based on layered neural network is characterized in that: comprise the following steps:
[0017] A. The pressure sensor is used to collect the pipeline pressure data, and the pressure value of each node of the entire pipeline is obtained, and the data set is normalized at the same time, so that its range is limited between [0-1];
[0018] B. Divide the data set into training data set and verification data set according to the proportion, determine the layer number of layered neural network, determine the complexity of each layer of neural network according to the scale of training data set, and train the first layer on the training data set. k layer neural network, k Represents a layered neural network;
[0019] C. On the validation dataset, set the first k The rejection threshold of the positive and negative sa...
