This article is about how the technical architecture of the Internet of things is formed. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The technical architecture of the Internet of things consists of the perception layer, the network layer and the application layer; the perception layer obtains the information of the object anytime and anywhere using RFID, sensors, QR codes, etc.; the network layer transmits the information of the object real-time and accurately through the integration of various telecommunications networks and the Internet; the application layer processes the information obtained by the perception layer.

What are the layers of the technical architecture of the Internet of things?

The Internet of things system has three levels.

One is the perceptual layer, that is, using RFID, sensors, QR codes, etc., to obtain the information of objects anytime and anywhere.

The second is the network layer, which transmits the information of objects real-time and accurately through the integration of various telecommunication networks and the Internet.

The third is the application layer, which processes the information obtained by the perceptual layer to realize practical applications such as intelligent identification, positioning, tracking, monitoring and management.

What is the bottom of the Internet of things?

The Internet of things, as the name implies, is the Internet connected to things, its core is still the Internet, but the extension and expansion on the basis of the Internet.

Its client extends and extends to any object to exchange information and communicate with each other. Therefore, the definition of the Internet of things is through radio frequency identification, infrared sensors, global positioning system, laser scanners and other information sensing devices, according to the agreed protocol, connect any object to the Internet for information exchange and communication, in order to achieve intelligent identification, positioning, tracking, monitoring and management of a network.

For example, for a tomato scrambled egg we ate in a restaurant, we can use the Internet of things technology, from a simple QR code or 3D code and other bar code technology, to know in detail the source of the ingredients: which farm the tomatoes in this dish come from, who picked them at what time, who tested them, and who shipped the tomatoes from where and where, its price, brand. Which hen laid the eggs, the health of the chicken, the condition of the whole henhouse, etc. Everything we want to know about this dish will be clear at a glance.

Let's talk about the Internet of things in more detail.

The Internet of things refers to the real-time collection of any object or process that needs to be monitored, connected or interacted through a variety of information sensing devices and technologies, such as sensors, radio frequency identification technology, global positioning system, infrared sensors, laser scanners, gas sensors, etc., and collect all kinds of necessary information such as sound, light, heat, electricity, mechanics, chemistry, biology, location, etc. A huge network combined with the Internet. Its purpose is to realize the connection between things and things, things and people, all things and the network, so as to facilitate identification, management and control.

Compared with the traditional Internet, the Internet of things has its distinct characteristics.

First of all, it is a wide range of applications of various sensing technologies. A large number of various types of sensors are deployed on the Internet of things, each sensor is a source of information, and different types of sensors capture different information content and information format. The data obtained by the sensor is real-time, collecting environmental information periodically according to a certain frequency, and constantly updating the data. Secondly, it is a kind of ubiquitous network based on the Internet. The important foundation and core of the Internet of things technology is still the Internet, through the integration of a variety of wired and wireless networks and the Internet, the information of objects can be transmitted in real time and accurately. The information regularly collected by sensors on the Internet of things needs to be transmitted through the network. Because of its huge quantity, it forms a huge amount of information. In the process of transmission, in order to ensure the correctness and timeliness of the data, must adapt to a variety of heterogeneous networks and protocols.

In addition, the Internet of things not only provides the connection of sensors, but also has the ability of intelligent processing and can intelligently control objects. The Internet of things combines sensors and intelligent processing, using cloud computing, pattern recognition and other intelligent technologies to expand its application fields. Analyze, process and process meaningful data from the massive information obtained by the sensor, in order to meet the different needs of different users, and find new application fields and application patterns.

The Internet of things is not so much a network as a business and application. Therefore, application innovation is the core of the development of the Internet of things, and innovation 2.0 with user experience as the core is the soul of the development of the Internet of things. It can be widely used in the following aspects:

1. The field of intelligent industry. Internet of things systems such as industrial production process control, production environment inspection, manufacturing supply chain tracking and product lifecycle inspection form an integrated management and monitoring platform to promote economic efficiency, production safety and energy saving and emission reduction.

2. The field of intelligent agriculture. The Internet of things systems, such as fine management of agricultural production, environmental monitoring of production and breeding, quality and safety management of agricultural products and product traceability, form a quality management platform for key agricultural products to ensure the safety of agricultural products.

3. The field of intelligent environmental protection. Internet of things systems such as real-time monitoring of urban atmospheric environment, water quality monitoring of key river basins and lakes, and real-time monitoring of industrial pollution sources form a real-time monitoring and early warning platform for key areas and industries to improve environmental quality.

4. The field of intelligent logistics. Cover inventory monitoring, distribution management, security traceability of the whole process of the Internet of things system, to form a cross-regional, industry, departmental logistics public service platform to improve logistics efficiency and ensure the safety and control of logistics.

5. The field of intelligent transportation. Internet of things systems such as traffic state perception and exchange, traffic guidance and intelligent control, vehicle positioning and scheduling, vehicle remote monitoring and service, etc., form a real-time urban traffic monitoring and management platform to improve the level of traffic management.

6. The field of intelligent security. Social security monitoring, dangerous chemicals transport monitoring and other Internet of things systems, form a monitoring and management platform for key areas and industries, and improve the information level of public safety management.

So we say that the Internet of things will be a new trend, it is the further expansion of the use of the Internet and innovation.
