Abstract: To improve the flexibility integration among heterogeneous manufacturing information systems of manufacturing enterprises,a semantic gateway-based reconfigurable information integration method was proposed.Based on the analysis of database metadata,the semantic annotations and concepts register for data field were made.According to the application needs of information integration,the data monitoring operation was configured,and the data change capture triggers were generated to deploy on manufacturing system databases.The trigger conditions of integration behavior for data change messages which captured by semantic gateway was configured on data change status,and their data projection as well as data operation based on the integration needs of different information systems were allocated.The concept semantic mapping was processed by semantic gateway process and integration messages were distributed to information systems.The data synchronization integration was realized by application integration proxy can.The researches were effectively verified by prototype system.
