What are the components of the Internet of things? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

What is the composition of the Internet of things?

The Internet of things can be divided into the following four layers, namely: perception layer, network layer, platform layer and application layer. The details are as follows:

1. Feel the different levels of knowledge

The perceptual layer is the basis of the overall architecture of the Internet of things and an important part of the integration of the physical world and the information world. In the perception layer, we can sense the information of the object itself and its surroundings through the sensor, so that the object also has the ability to "speak and release information", such as sound sensor, pressure sensor, light intensity sensor and so on. The perceptual layer is responsible for collecting and obtaining information for the Internet of things.

2. Network construction layer

The network layer plays a connecting role in the whole architecture of the Internet of things, which is responsible for transmitting perceptual information to the upper layer and commands to the lower layer. The network layer transmits the information collected by the perception layer to the IoT cloud platform, and is also responsible for transmitting the instructions issued by the IoT cloud platform to the application layer. The network layer mainly transmits huge amounts of information through the Internet of things, the Internet and mobile communication networks.

3. Platform management

Platform layer is the core of the overall architecture of the Internet of things, which mainly solves the problems of how to store data, how to retrieve data, how to use it, and how to protect data security and privacy. The platform management is responsible for the effective integration and utilization of the information collected by the perception layer through big data, cloud computing and other technologies to provide scientific and effective guidance for people to apply to specific fields.

4. Integrated application layer

The Internet of things will eventually be applied to various industries. After the information transmitted by objects is processed in the IoT cloud platform, the valuable information excavated will be applied to real life and work, such as intelligent logistics, smart medical care, food safety, smart parks and so on.

The characteristics of the Internet of things

The basic characteristics of the Internet of things from the perspective of communication objects and processes, the information interaction between things and things, people and things is the core of the Internet of things. The basic characteristics of the Internet of things can be summarized as overall perception, reliable transmission and intelligent processing.

Global perception-can use radio frequency identification, QR codes, smart sensors and other sensing devices to perceive and obtain all kinds of information of objects.

Reliable transmission-through the integration of the Internet and wireless networks, the information of objects can be transmitted real-time and accurately, so that information can be exchanged and shared.

Intelligent processing-use a variety of intelligent technologies to analyze and process the perceived and transmitted data and information, so as to realize the intelligence of monitoring and control. According to the above characteristics of the Internet of things, combined with the point of view of information science, around the flow process of information, we can sum up the functions of the Internet of things in processing information:

(1) the function of obtaining information. It mainly refers to the perception and recognition of information, which refers to the perception and sensitivity to the attribute state of things and the way they change; the identification of information means that the state of things can be expressed in a certain way. (2) the function of transmitting information. It is mainly the link of sending, transmitting and receiving information, and finally the task of transmitting the state information of things and their changes from one point in time (or space) to another, which is often called the communication process. (3) the function of processing information. Refers to the information processing process, the use of existing information or perceived information to produce new information, is actually a decision-making process. (4) the function of applying effect information. It refers to the process in which the information finally comes into play, and there are many forms of expression. The more important thing is to keep the object in a pre-designed state by adjusting the state of the object and its transformation.

This is the answer to the question about what components of the Internet of things are shared here. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
