The invention relates to the technical field of knowledge maps and large models, and discloses a fully-mechanized
coal mining equipment
large model decision support method and
system. The method comprises the following steps: defining entities in
data information of fully-mechanized
coal mining equipment and a relationship between the entities to form triple data; converting the triple data into question and answer pairs based on the question and answer template, and optimizing the question and answer pairs; establishing a large
language model, training the large
language model based on question and answer pairs, performing
fine tuning on the large
language model based on a LoRA technology, and performing quantification
processing on the
equipment state in combination with fuzzy comprehensive evaluation to obtain a quantification result; the
system uses the fine-tuned large language model to carry out entity and intention recognition on a
natural language input by a user, a Cypher
query statement is constructed to carry out query in a
graph database, sub-graph information is obtained, the sub-graph information and the quantization result serve as cue words and are transmitted to the large language model, and retrieval information supporting
large model decision making is obtained. The operation and maintenance efficiency of the fully-mechanized
coal mining equipment is improved.
