Three key features of iot

All kinds of terminals realize "comprehensive perception"; The convergence of telecommunications networks and the Internet enables "reliable transmission ": cloud computing and other technical teams" intelligently process "massive amounts of data.

Total perception

Information acquisition and acquisition of objects at any time and place through RFID (RFID), sensors, locators and QR codes. Sensing includes sensor information collection, collaborative processing, intelligent networking and even information services to achieve the purpose of control and command.

Reliable transmission

It refers to the real-time remote transmission of the received perceptual information through the integration of various telecommunication networks and the Internet, so as to realize the interaction and sharing of information, and carry out various effective processing. In this process, it is often necessary to utilize existing telecom operating networks, both wireless and wired. Since sensor networks are local area wireless networks, wireless mobile communication networks and 3G networks are strong supports for the Internet of Things.

Intelligent processing

It refers to the use of cloud computing, fuzzy recognition and other intelligent computing technologies to analyze and process the massive data and information received at any time across regions, industries and departments, improve the insight of the physical network world, economic and social activities and changes, and realize intelligent decision-making and control.

Three levels of iot

The bottom layer is the data perception layer, the second layer is the network layer of data transmission, and the top layer is the application layer.

Perceptual layer

The sensing layer includes data acquisition devices such as sensors, including the sensor network before the data access gateway. The perception layer is the foundation of the development and application of iot. The main technologies involved in the sensing layer are RFID technology, sensing and control technology and short-range wireless communication technology, including chip research and development, communication protocol research, RFID materials, intelligent power saving and power supply.

Network layer

The network layer of the Internet of Things will be built on top of existing mobile communication networks and the Internet. The network layer perception data management and processing technology is the core technology to realize the data-centric Internet of Things, which includes the theory and technology of data storage, qcm6125 query, analysis, mining, understanding, decision and behavior based on perception data. Cloud computing platforms, as storage and analysis platforms for large amounts of perceived data, will become an important part of the iot network layer.

Application layer

Through the analysis and processing of the perception data, qualcomm qcm6490 the application layer of the Internet of Things provides users with rich and specific services, which are divided into monitoring type (logistics monitoring, pollution monitoring), query type (intelligent retrieval, remote meter reading), control type (intelligent transportation, smart home, street lamp control), scanning type (mobile wallet, highway toll collection) and so on.

Application layer is the purpose of the development of the Internet of Things, software development, intelligent technology control technology will provide users with a variety of Internet of Things applications.
