An Efficient IIoT Gateway for Cloud–Edge Collaboration in Cloud Manufacturing

The cloud manufacturing system can provide consumers with on-demand services, which significantly improve the utilization rate of distributed resources and response speed personalized product needs. In platform, successful implementation various industrial applications relies on uploading streaming related field-level data. For example, realization service composition application should match tasks according to their working state data performance measurement Therefore, this paper proposes a integration analysis framework based cloud–edge collaboration Industrial Internet Things (IIoT). A service-oriented information model is established uniformly describe operational functional attributes heterogeneous resources. Secondly, real-time transmission method high-volume field sensor message middleware proposed realize remote monitoring efficient distribution Finally, mechanism put forward train update parameters artificial intelligence models deployed at edge gateways. experiment, taking computer numerical control (CNC) lathe as an effectiveness resource access verified. Taking fault diagnosis CNC efficiency for updating
