With the development of cloud computing

cloud manufacturing technology has become an important means to integrate and distribute manufacturing resource. The application of the cloud manufacturing is grounded on the technology of industrial device connection to the cloud platform. However

problems as a wide variety of communication protocols for heterogeneous devices

the complexity of data security guarantee and inconsistent data interface standards make it difficult for industrial equipment to connect to the cloud platform. This paper has designed such a connection model with IMQ (Industrial Message Queue) as the pivot

which provides the industrial device an access to cloud platform. This model has defined the capabilities of IMQ and IMQ adapters making it possible for heterogeneous devices to connect to the cloud platform. Besides

it has set up an agreed protocol for IMQ adaptation and data publishing which can unify data interface standards and ensure data security. This connection model puts forward new ideas and new methods for industrial device connection to the cloud platform in the future.
