The invention relates to the cross technical field of intelligent manufacturing, industrial
artificial intelligence, a
big data technology and high-end material
engineering, in particular to a
neodymium iron
boron production process management method based on
artificial intelligence and a
big data technology. According to the method, a'
big data platform + AI
algorithm engine 'double-wheel-driven
intelligent management system is constructed,
artificial intelligence technologies such as
machine learning,
deep learning,
knowledge graph and digital twinning are deeply fused with a
mass multi-source heterogeneous
big data processing technology, and the method runs through the whole process of
neodymium iron
boron material production. The core comprises the steps of constructing a
unified process data lake based on a big data technology, and realizing fusion treatment of multi-
source data; establishing a quantitative correlation model of process parameters and product performance based on a
machine learning
algorithm; digital expression and intelligent reasoning of
process knowledge are realized based on the
knowledge graph; constructing a
virtual process simulation optimization platform based on a digital twinning technology; and finally, a continuous evolution
closed loop of
data acquisition,
feature extraction, model training,
intelligent decision making and feedback optimization is formed. The technical problems that in traditional
neodymium iron
boron production, value mining of
mass data is insufficient, process decision depends on artificial experience,
quality control lags behind, and the
process optimization period is long are effectively solved, and fundamental transformation of the production process from experience driving to data and intelligent double-wheel driving is achieved.
