The invention discloses a
deep learning-based deep fusion network
production line fault prediction method, which comprises the following steps of: firstly, acquiring
SCADA (
Supervisory Control And
Data Acquisition)
system or sensor data of an automatic
production line, and carrying out data preprocessing,
feature extraction and fault prediction
label construction; then a deep fusion network 1D-CNN-LSTM-Attention-DCE model combining a one-dimensional convolutional network, a long short-
term memory neural network, a fusion attention mechanism and a dynamic
cross entropy loss function DCE is established, the preprocessed data is input into the constructed model for training, and finally the trained model is used for fault prediction to obtain a fault prediction result. According to the method, a 1D-CNN-LSTM-Attention-DCE fault prediction model is provided, local features are extracted from
time sequence data by using the 1D-CNN, then a long-
time dependency relationship is captured through LSTM, and finally
weight distribution of key features is enhanced through an attention mechanism, so that the
processing capability of the fault prediction model on complex
time sequence data is comprehensively improved, and the fault prediction efficiency is improved. And the fault of the
production line can be accurately predicted within a certain time length range.
