This invention relates to the field of
industrial equipment safety monitoring technology, and discloses a data-driven intelligent early warning method and
system for the degradation risk of organic
heat transfer fluids. The method includes: acquiring multimodal
monitoring data of the organic
heat transfer fluid, performing preprocessing and
feature extraction to obtain entropy yield and
acoustic emission activity index; inputting the entropy yield,
acoustic emission activity index, and medium quality parameters into a mechanism classification neural
network model to obtain the determination probability of the degradation mechanism; according to the determination probability, inputting the
feature vector into the corresponding target
branch neural network to obtain an instantaneous
risk index; predicting the time required for the medium quality parameters and entropy yield to reach a safety threshold, taking the minimum value as the predicted failure time, and calculating the degradation resilience value in conjunction with the
planned maintenance time; and determining the comprehensive
risk level based on the instantaneous
risk index and the degradation resilience value. This solution can achieve
early detection of degradation trends and distinguish different degradation mechanisms, improving assessment accuracy and making maintenance strategies more targeted.
