Currently,there are still some problems with IoT,specifically in:one is that the IoT gives priority to vertical service system;another is the lack of cross-system resource sharing.To solve the above problems,a scalable intelligence service architecture of IoT in which a unified service data model was proposed and a message middleware were built to overcome the multi-source heterogeneous problems in the data structure,data platforms and operating systems. In addition,a usage authorization mechanism was proposed to support security and privacy in the IoT environment, contributing to a scalable,secure and reliable intelligence open service platform for IoT.Finally,a prototype system was designed and concrete system was given to verify the feasibility and superiority of the proposed architecture.
