Design And Implementation Of Common Resource Management System In Iot

With the development of the Internet of Things(IoT)technology,the Internet of Things has become more and more widely used.The types of access devices have also grown explosively and become more and more numerous.As a result,the heterogeneity of devices in the IoT has become more and more obvious.Today's IoT platform architecture technology keeps IoT applications and devices in a vertical development mode,making it difficult for devices to directly interact with each other and share information.At the same time,different application areas cannot directly interconnect and interoperate.As a result,IoT applications are limited in their expansion.After research and analysis,this paper proposes a common resource management platform architecture for the IoT.Through unified abstract description and data representation of heterogeneous devices,unified management of the Internet of Things data is implemented.At the same time,based on the real-time data synchronization mode,the Internet of Things data interaction and application efficiency are improved.After analyzing the common characteristics of the IoT devices,combined with the investigation of the abstract methods of the devices,the device is abstractly expressed in terms of attributes,controls,and data.Encapsulate device data and controls in the form of resources for a unified description.The interaction between data and control is implemented by building a uniform resource interaction mode with heterogeneous devices to facilitate interconnection and interoperability among different devices.In view of the simple and fixed application-to-device interaction,it is difficult to dynamically organize and construct the device interaction data based on the application requirements.This paper proposes that based on the device resources formed by the abstraction of devices' raw data and combined with the application logic of the IoT,the device resources are fused to build application-oriented resources.So that the IoT data can be organized and represented from the application level and the efficiency of data scheduling and utilization of the IoT is improved.Combining different application fields and the requirements for data exchange between devices,this paper proposes the concept of a distributed directory tree to represent device internetworks and manage interactive data.And based on the resource data real-time synchronization mechanism to achieve data interaction,improve the data interaction real-time and high efficiency.For the intelligent traffic scenario,the architecture of the Io T resource management platform is verified,which realizes the unification of the IoT platform and the unified management of heterogeneous devices in the intelligent traffic scenario.At the same time,the urban traffic efficiency is improved by implementing intelligent congestion detection applications in the urban road network,and traffic information sharing through resource synchronization.Through comparison experiments,it shows that this platform architecture is effective and timely for information management and sharing in IoT applications.
