Usually, what is the "Internet of Things" that people talk about? Generally speaking, the Internet of Things is a network connected with things. In fact, it is still based on the Internet, but it has been extended and expanded to any object and directly exchange information and communicate with each other. It can be said that the Internet of Things and the Internet are equal to a smart earth. "But what is the Internet of Things? It is difficult to give a clear definition now.

When the concept of "Internet of Things" was put forward in 1999, it was defined as: connecting all items with the Internet through information sensing devices such as radio frequency identification to realize intelligent and digital identification and management. Later, there was a saying that the Internet of Things is an "Internet of Things" network covering everything in the world by using RFID, wireless data communication and other technologies.

In fact, it was put forward a long time ago, but it was not until 2008 that in order to promote the development of science and technology and find new economic growth points, governments all over the world began to attach importance to the next generation technology planning, so they set their goals on the Internet of Things. Now many enterprises are targeting the Internet of Things market, which will be a very promising direction.

Under the background of the country's efforts to promote the integration of industrialization and informatization, the Internet of Things will be a more realistic breakthrough in the informatization process of industry and even more industries. Human beings are inseparable from the Internet of Things, which is closely related to human beings. We can now see some closed-loop applications of RFID technology in many fields and industries. In these first successful cases, the information of items has been automatically collected and uploaded to the Internet, and the management efficiency has been greatly improved. Some dreams of the Internet of Things have been partially realized. Every successful case of RFlD can be regarded as a prototype of the Internet of Things. The embryonic form of the Internet of Things is just like the early form of the Internet, LAN. Although it plays a limited role, it shows great prospects.
