The Research And Design Of System Merging Mechanism Based On Internet Of Things

With the technology development of the Internet of Things (IoT), more and more applications have infiltrated every aspect of our life. However, the existing applications are independent, single functional, data inconsistency between application systems, resource reuse difficulties, lack of interoperability of the linkage mechanism. IoT is a typical application-driven network. Different applications have different requirements for sensor nodes and function mechanisms."Vertical" applications which can be looked at "point" applications cannot construct "net" applications and "plane" applications. Since the applications of IoT are more and more widely used, independent business of IoT application cannot meet the needs of largely rapid development of IoT business.In order to turn the local applications, closed and single sensing devices in the IoT to standardized, open, cross-interdisciplinary shared resources, and improve resource reusability. Using the service integration technologies, which make the decentralized, small-scale date, networks, and application resources together, to construct a unified IoT common service supporting system for the public.Based on service oriented architecture (SOA), combined with the characteristics of the IoT, the paper proposed a service bus architecture based on IoT, which can well support the integration of sensing devices and services. For the sensing devices, this architecture can shield the differences and realize the unified operation and management. For the service components on application layer, it can open, support unified, standard service interfaces for service consumers.The paper mainly focuses on the following aspects. 1. Comparison of existing system integration technologies and combined with the specific features of IoT, then, proposes a merging scheme about the IoT service bus(IoTSB). It includes the sensing devices combination and service components combination.2. According the above solution, according to the differences among the devices, design and implement the merging scheme on different IoT terminal equipments, and provide unified operation control interfaces.3. According the above solution, design and implementation of different merging scheme on the Internet of components, including communication interface service component, service component of the registration management, the service component of release to service component calls uniform interface, etc.4. Verify the feasibility of the IoT service bus architecture. Using the IoTSB on the existing supporting platform to integrate the dispersive services.Finally, the research results have been verified in actual system.
