The school enterprise alliance of China's Internet of Things defines the Internet of Things as almost all current technologies and Website production The combination of Internet technology enables real-time sharing of environment and status information between objects, as well as intelligent collection, transmission, processing and execution. In a broad sense, the current application of information technology can be included in the scope of the Internet of Things.

In its famous science and technology fusion model, it proposed that the Internet of Things is the science and technology concept and application closest to the top of the model at present. The Internet of Things (IoT) is a network based on information carriers such as the Internet and traditional telecommunications networks, which enables all ordinary physical objects that can be independently addressed to achieve interconnection. It has three important characteristics: intelligent, advanced and interconnected.

The ITU Internet report released by the International Telecommunication Union (ITU) defines the Internet of Things as follows: through two-dimensional code reading equipment, radio frequency identification (RFID) devices, infrared sensors, global positioning systems, laser scanners and other information sensing equipment, according to the agreed protocol, any item is connected to the Internet for information exchange and communication to achieve intelligent identification, positioning A network that tracks, monitors, and manages.

According to the definition of the International Telecommunication Union (ITU), the Internet of Things mainly solves the interconnection between things (Thing to Thing, T2T), people to Thing, H2T, and people to human, H2H. But different from the traditional Internet, H2T refers to the connection between people and goods by using general devices, which makes the connection between goods more simplified, while H2H refers to the interconnection between people without relying on PCs. Because the Internet does not consider the problem of connecting any item, we use the Internet of Things to solve this traditional problem. As its name implies, the Internet of Things is a network connecting goods. Many scholars often introduce the concept of M2M into the Internet of Things, which can be interpreted as Man to Man, Man to Machine, and Machine to Machine. In essence, the interaction between people and machines, and between machines, is mostly to realize the information interaction between people.
