Abstract:

In order to solve the problem that a large amount of multi-source heterogeneous structured and unstructured knowledge in the operation and management of cable crane is difficult to reuse, a large number of technical specifications, expert experience and other safety knowledge accumulated in the installation and operation and maintenance of cable crane were analyzed, and related entity classes of cable crane operation were extracted. A quintuple model was used to structurally express the safe operation of the ontology knowledge of the cable crane, and the binary relationship between classes was established. Then, the ontology expression language in Protégé was used to represent it programmatically. The ontology knowledge base of the cable crane entity, safety early warning and an emergency plan was constructed. 3D scene model of the cable crane was constructed using 3Dmax software, and then the model was imported into Unity3D engine. Knowledge retrieval of the ontology knowledge base was realized through user interface design and interaction functions in the engine. At the same time, based on the existing examples of faults and accidents, the corresponding emergency plans were associated with the hidden dangers existing in each entity of the cable crane. Finally, a complete 3D visualization platform for safe operation knowledge retrieval of cable cranes was constructed. The results show that all kinds of safe operation knowledge of cable-winch can be centrally and effectively managed by constructing an ontology knowledge base, and a knowledge retrieval platform combined with an ontology knowledge base can effectively realize efficient query and reuse of knowledge.

Key words: safe operation of the cable crane, knowledge representation, ontology construction, knowledge base, knowledge reuse
