Large numbers of semantically heterogeneous datasources exist in information integration of the equipment.It baffles the share and exchange of infromation.Because the ontology can be used to describe the hidden relations between information and describe the concept model of information system on semantic and knowledge.So it can effectively solve the semantic heterogeneity in information integration.On the analysis of ontology-based information integration,puts forward an equipment basic information integration framework based on hybrid ontology,which adopts Wrapper/Mediator structure.Then level and key technique of the framework are given.The construction of equipment Index Architecture and the problem of query processing based on ontology are researched.The feasibility and effectiveness of the information integration method on the basis of ontology are verified in the equipment information integration.
