Design And Implementation Of Internet Of Things Device Access System

In recent years,the high-speed development of Internet information technology has affected the development of Internet of Things technology,which has attracted extensive attention from academic and industrial circles.More and more industry fields have applied the Internet of Things technology,benefitting from the Internet of Things technology.The continuous expansion of its application fields has also led to a sharp increase in the scale of its applications.The number of devices in the Internet of Things are also increasing.The Internet of Things is used for the interaction between the information from devices to devices,devices and applications through Internet transmission protocols.It can be seen that the devices in the Internet of Things play a vital role in the application.All applications on internet of things require data services from the device end.However,the number of applications and devices in the Internet of Things is currently very diverse.The protocols are not the same,so a system is needed to uniformly manage and control the devices in order to provide good services to the upper layers.The device access system designed in this paper aims to manage and control the device uniformly and transmit the data collected by the device to the upper application accurately and securely.Firstly,the paper introduces the research backgrounds and significance of the topic,and then it introduces related technologies in the Internet of Things,including the Internet of Things wireless communication technology,and the commonly used application layer protocol,and then the device access system is shown how to be designed and implemented,Combined with the complex network environment in the Internet of Things,JSON is used as a data exchange format for data transmission and communication.For the security problem of data in the system,considering the limited resources in the Internet of Things,a hybrid encryption method is proposed to ensure the security of the system and the accurate and complete transmission of the data.Finally,it is tested.It shows the feasibility of the program.
