To improve the learning effect and recognition accuracy in fault identification of boiler tube acoustic signals, different information fusion mechanisms were used in this study. Specifically, feature vector parallelism and splicing techniques are used to form the feature layer, while the decision layer is formed using average and maximum score approaches. A fault identification method of multifeature boiler tube acoustic signal based on a deep residual shrinkage network is proposed. First, the first-order and second-order differential characteristics of the acoustic signal spectrum were calculated separately, considering the variations of acoustic wave sensors on the boiler tube. This process constructs a three-channel feature set, which serves as the input feature vector of the two-dimensional network. Subsequently, an attentional mechanism is introduced to construct a baseline model using a combination of a convolutional neural network and a bidirectional short and long memory network. Additionally, a deep residual shrinkage network is used to optimize the allocation of channel weights within the two-dimensional network to improve the fault identification accuracy of the model. Extensive experimental results show that: it is a more effective strategy to construct the information fusion mechanism of the feature layer by using feature vector parallel fusion; compared with the baseline model, the unweighted average recall rate has increased by 4.32%, highlighting significant improvements in the recognition accuracy of the model presented in this paper.
