Following computers, the Internet and mobile communication networks, qcm6125 the Internet of Things has become a new direction in the information industry and has been applied in many places. As a new technology field, the architecture of the Internet of Things also has its basic hierarchy, with its own domains and functions.
Technically speaking, the realization of iot capabilities requires the integration of multiple information technologies in perception, network and applied research. Therefore, the basic theoretical architecture analysis framework of the Internet of things can be divided into three levels according to the direction of data technology industry integration: perception layer, network layer and application layer.
So what are the three layers, the perception layer, the network layer and the application layer, qualcomm qcm6490 and what are their functions?
1. Perceptual layer. The perception layer is the bottom layer of the Internet of Things, which mainly solves the core capability of the integrated perception of the Internet of Things. There are a large number of sensors of various types on the Internet of Things, each of which is a unique source of information. Sensor devices such as radio frequency identifiers, global positioning systems, and infrared sensors in the Internet of Things can identify and obtain data information of various foods, so as to achieve intelligent control of objects.
2. Network layer. The network layer mainly solves the problem of remote data transmission acquired by the perception layer. It is the middle layer of the Internet of Things, that is, the central nervous system of the human body and brain, which is responsible for transmitting and processing the information captured by the sensory layer, forming a transparent data transmission between the two terminal systems.
3. Application layer. The application layer of the Internet of Things provides a wealth of iot based applications, and is the interface between the Internet of Things and users (including people, organizations and other systems).
The research on the industry development characteristics of the Internet of Things mainly reflects the enterprises in their application fields. At present, China's smart home, industrial monitoring, public transportation safety, green ecological agriculture, urban economic management and other different industries have tried to apply the Internet of things. The application layer of the Internet of Things takes the collection and interconnection network as a basis to deeply, extensively and automatically collect a large amount of data information to achieve more intelligent applications and services.
