I would like to share with you what is the main structure of the Internet of things. I believe most people do not know much about it, so share this article for your reference. I hope you will learn a lot after reading this article. Let's learn about it!

The architecture of the Internet of things is mainly divided into: 1, the perception layer, which is the basis of the development and application of the Internet of things; 2, the network layer, a converged network based on the existing communication network and the Internet; and 3, the application layer, the Internet of things technology and professional technology are integrated, and the perceptual data analyzed and processed are used to provide users with rich and specific services.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

The architecture of the Internet of things can be divided into three layers: perception layer, network layer and application layer.

The perceptual layer. It is the basis of the development and application of the Internet of things, including data acquisition devices such as sensors or card readers, and sensor networks before data access to the gateway. The sensing layer takes RFID, sensing and control, short-distance wireless communication as the main technology, and its task is to identify objects and collect relevant information in the system, so as to realize the understanding and perception of "things".

Network layer. It is a converged network based on the existing communication network and the Internet. The network layer is connected with the mobile communication network and the Internet through various access devices. Its main task is to realize the transmission, preliminary processing, classification and aggregation of information through the existing Internet, radio and television network, communication network, etc., which is used to communicate the perception layer and the application layer. At present, the strength of domestic communication equipment and operators is strong, which is the most mature part in the field of Internet technology in China.

Application layer. Is the Internet of things technology and professional technology integration, the use of analysis and processing of perceptual data to provide users with a wealth of specific services. The application layer is the purpose of the development of the Internet of things. The application of the Internet of things can be divided into control type, query type, management type and scanning type, etc., which can achieve a wide range of intelligent application solutions through existing mobile phones, computers and other terminals.

Data expansion:

The whole structure of the Internet of things can be divided into two parts: radio frequency identification system and information network system. Radio frequency identification system is mainly composed of tags and readers, both of which communicate through RFID air interface. After the reader obtains the product identification, it uploads the product identification to the middleware of the information network system through internet or other communication means, then obtains the object name of the product through ONS parsing, and then obtains various related services of product information through various interfaces of EPC information services. The operation of the whole information system will rely on the network system of internet, using the communication protocol and description language developed on the basis of internet.

Therefore, we can say that the Internet of things is the sum of all kinds of physical product information services based on internet. From the perspective of application, the three levels of the Internet of things are worth paying attention to, that is to say, the Internet of things is composed of three parts: one is the sensor network, which is based on QR code, RFID and sensors to identify "things". The second is the transmission network, that is, through the existing Internet, radio and television network, communication network to achieve data transmission and calculation. Third, the application network, that is, the input and output control terminal.

These are all the contents of this article entitled "what is the main structure of the Internet of things?" Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
