What are the three levels of the Internet of Things architecture?
The architecture of the Internet of Things was mainly divided into three layers: the perception layer, the network layer, and the application layer. The hierarchy here was not a concept of hierarchy. The perception layer was composed of various sensors and sensor gateway. It was the source of the Internet of Things to identify objects and collect information. Its function was equivalent to nerve endings such as human eyes, ears, nose, throat, and skin. Its main function was to identify objects and collect information. The network layer was composed of various Private Cloud, the Internet, wire and wireless communication networks, network management systems, and cloud computing platforms. It was like a human's nerve center and brain, responsible for transmitting and processing the information obtained by the sensory layer. The application layer was the interface between the Internet of Things and users (including people, organizations, and other systems). Combining it with industry needs to realize the intelligent application of the Internet of Things was the fundamental goal of the development of the Internet of Things.
