The invention provides an
icing situation sensing method and
system based on time-space fusion, and the method comprises the steps: obtaining
sensing data which comprehensively reflects the formation and
spatial distribution of
icing from different angles through a multi-point monitoring mode, and extracting key parameters, namely multi-source characteristic parameters, representing the
icing situation from the
sensing data, the method comprises the following steps: carrying out weighted fusion on icing data change rate, temperature deviation value and maximum icing difference of icing data on a blade based on an attention mechanism, adaptively highlighting key features, weakening the weight of secondary features, and obtaining fusion features; and then, on the basis of a related
topological graph constructed by fusion features, a graph neural network and a Transform network are utilized to capture
spatial distribution features and
time evolution laws of icing, so that the limitation that
spatial correlation is difficult to describe only depending on a
time sequence model traditionally is overcome, spatial features and
time sequence features are effectively extracted, final spatial-temporal features are obtained, and the
spatial distribution features and the
time evolution laws of icing are extracted. And prediction is carried out based on the spatial-temporal characteristics so as to improve the precision of icing situation
perception.
