What are the main technologies of iot? What are their applications?

Now that you're reading this article, how do you read it? On a cell phone? Using a computer? Or a tablet? automatic probe station No matter what device you use, it is connected to the Internet.

The emergence of the Internet is a very beautiful thing, it provides us with all kinds of convenience that were not possible before.

Connecting devices to the Internet yields some amazing benefits that we feel through the use of smartphones, laptops, and tablets, but in fact for all other devices, yes, I'm talking about all of them. The Internet of Things is actually a very simple concept that means connecting everything in the world to the Internet.

The concept of the Internet of Things is confusing not because it is too narrow, private 5g but because it is too broad. There are so many applications and possibilities for iot that it can be difficult to form a clear definition of iot in your mind.

From intelligent control of lights to shared use of bicycles, from smart manhole covers to smart agriculture, the development of the Internet of Things industry spans a very large space. It is no exaggeration to say that all relevant industries are related to the Internet of Things.

Principles of Internet of Things technology

The Internet of Things principle technology is actually based on the computer Internet, using RFID, wireless data communication and other technologies to build a "Internet of things" covering tens of thousands of buildings around the world. private lte In this network, buildings can "communicate" with each other without human intervention. Its essence is the use of radio frequency automatic identification (RFID) technology, through the computer Internet to achieve the automatic identification of goods (goods) and information sharing.

The core technology of the Internet of Things is still in the cloud, and cloud computing is the technical core to achieve the Internet of Things. The three key technologies and areas of the Internet of Things include key technologies: sensor technology, RFID tags, and embedded system technology. Fields: Public affairs management (energy conservation, environmental protection, traffic management, etc.), public social services (medical health, home building, finance and insurance, etc.), economic development and construction (energy, electricity, logistics and retail, etc.).

Sensor technology is a key technology in computer applications, which converts analog signals in transmission lines into digital signals that can be processed by computers.

RFID, the full name of Radio Frequency Identification, that is, radio frequency identification information technology, is a comprehensive analysis technology that integrates radio frequency data technology with the development of embedded system technology. In the near future, it will be widely studied and applied to automatic pattern recognition, goods and logistics enterprise management.

Embedded system technology is a complex technology which integrates computer software, computer hardware, sensor technology, integrated circuit technology and electronic application technology.

The use of decentralized scenarios, centralized technology.

The use scenario of the Internet of Things is very consistent: collection + transmission + calculation + display

The intelligent terminal of the Internet of Things collects information data, transmits the data to the server, the server stores and processes the relevant data, and the data is displayed to the user.

For example, bicycles can be shared, and the positive development process is: bicycle companies obtain GPS location data, report it to the server through the 2G network system, the server, and record information related to the market position of the bicycle, and users view the location of the bicycle on the APP side. The reverse learning process is: the user issues a request for unlocking to the server, the server needs to send the unlocking instruction to the bicycle through the 2G network, and the bicycle company executes the unlocking instruction.

The applications of the Internet of Things, regardless of size, are based on two processes of forward data acquisition and reverse command control.
