Cable crane safe operation knowledge multiplexing method based on Protege

The invention provides a Protege-based cable crane safe operation knowledge multiplexing method. The method comprises the following steps of 1, extracting entity classes related to all operation modules of a cable crane; 2, basic ontology modeling meta-languages are introduced, a unified standardized ontology representation model is established, and a knowledge representation quintuple model based on a cable crane operation ontology is constructed; step 3, taking the Protege as an ontology construction tool, using an OWL formalized ontology description language in the Protege to structurally represent the safe operation process of the cable crane, and constructing an ontology knowledge base; 4, establishing a cable crane safety operation ontology evaluation standard; step 5, constructing a cable crane operation three-dimensional scene model, then importing the model into a Unity 3D engine, and designing an ontology multiplexing function structure framework; and step 6, based on the existing fault and accident
