Design And Implementation Of The Common Platform Of Internet Of Things

Under the background that the construction of Smart cities gradually becoming a trend in China,it is able to achieve network integration of sensing devices,information interaction,data sharing,function collaboration and optimization of management and service using technology of Internet of things(IoT),based on which better intelligent applications can be created.A reference architecture of IoT application systems is given in this paper.And based on this architecture,we propose a realizable technological architecture of the common platform of IoT based on open source software and carry out a detailed design of the system functions.Based on the design concept of common platform,ESB technology is used to design the service layer,and distributed storage and access technology is used to provide high data processing.This paper gives a detailed analysis of the object management subsystem,integration subsystem,and the service management subsystem.All those subsystems play an important supporting role for entire IoT application systems as a part of the common platform.Firstly,this paper carries on the requirement analysis of three subsystems of the common platform.Then system architecture,system module division,system interface module and database design are given,and on this basis,three subsystems are implemented.The function and performance of the subsystems are tested at the end of the paper.
