Internet of Things technology matrix "six layers, two domains" structure
With reference to the natural composition of IOT technology and the hierarchical structure of IT industry structure and IoT business perspective, IoT technology matrix can be divided into six levels. From bottom to top: element layer, device layer, terminal and node layer, (information) resource convergence layer, platform service layer and application layer.
The technical matrix is ​​divided into two "domains": the "edge domain" and the "cloud domain". The boundaries of the two "domains" are mainly embodied in the terminal and node layers, the resource aggregation layer and the application layer.
Internet of Things six-layer technology
1, the element layer
The natural phenomena and effects in information science are a collection of basic information sciences and the basis for building a device layer (the most basic technical element of the Internet of Things). Including electrical, electromagnetic induction, microwave theory, circuit theory and so on.
2, the device layer
The basic components in the information industry are mainly all kinds of electronic components, circuit modules and functional boards, including chips, circuit boards, power supplies, memory, signal input and output devices, sensors and actuators. At this level, "software" includes, in addition to the circuit design, an embedded development program that essentially "software" its internal electronics before it leaves the factory.
3, terminal and node layer
Mainly includes two types of physical entities:
A. Internet of Things terminals, including non-intelligent terminals (also called "dumb terminals") generally do not have the capability of data processing and can only report sensor data or receive manipulation data via the network; intelligent terminal devices such as industrial robots; User smart terminal (mobile phone, notebook).
