Abstract: Aiming at the problems of heterogeneous source data,difficulty in sharing,and high cost in equipment interconnection and intercommunication,a CNC equipment modeling standardization,interconnection and interoperability method were proposed based on MTConnect.An extensible unified description semantics of equipment heterogeneous information and a mapping method for MTConnect information model were proposed to realize extensible standardized modeling of heterogeneous equipment.On the basis of information model mapping,an integrated configurable middleware design,data acquisition based on HTTP protocol and equipment interoperability technology based on Interface components were proposed to reduce the difficulty of equipment interconnection and interoperability.A verification platform containing multiple types of mainstream CNC systems were built to verify the feasibility of the vertical interconnection and horizontal interoperability of the architecture,methods and technologies.As a standard method,it had advantages in terms of security,scalability and cost control compared with the direct-driven interconnection and interoperability.
