The invention provides a
power station key
equipment temperature monitoring and early warning method and
system, and belongs to the field of
temperature monitoring, and the method comprises the following steps: S1, collecting temperature data of
power station key equipment, and carrying out the preprocessing of the temperature data; s2, performing
feature extraction on the preprocessed one-dimensional
time sequence data and the preprocessed two-dimensional image data to obtain a first feature and a second feature, and fusing the first feature and the second feature to obtain a fused feature; s3, based on the fusion features, constructing a
deep learning prediction model comprising a short-
term memory module and a long-
term memory module, and optimizing hyper-parameters of the
deep learning prediction model by using a distributed
hybrid optimization
algorithm to obtain an optimized
deep learning prediction model; and S4, acquiring temperature data of the key equipment of the
power station in real time through an
industrial internet platform, predicting the future temperature of the key equipment of the power
station by using the optimized deep learning prediction model to obtain a prediction result, and performing adaptive temperature early warning according to the prediction result and a temperature threshold value of the key equipment of the power
station. According to the invention, potential temperature abnormity can be identified in time, the accuracy of temperature prediction is remarkably improved, and the sensitivity and reliability of an
early warning system are greatly improved.
