Original title: "Internet of things, what's so magical about you?" "

With the vigorous development of 5G, the concept of Internet of things has gradually come into everyone's attention. I'm sure you've all heard of it. But what on earth is the Internet of things?

The Internet of things (Internet of Things,IoT) is an information carrier based on the Internet and traditional telecommunications networks, which enables all ordinary physical objects that can be addressed independently to form an interconnected network.

The editor will explain it in human words. Popularly speaking, the Internet of things is to connect objects to the network, so that objects and objects, objects and people can exchange information. The Internet of things is the Internet connected to everything, and it is the extension and expansion of the traditional Internet.

1. The concept of the Internet of things if we want to understand the Internet of things, let's start with the Internet.

To put it simply, the Internet is a huge network that connects all computers together, so that computers can exchange information. Later, pad, mobile phones and other mobile terminals have access to the Internet, the formation of the mobile Internet.

With the continuous development of science and technology, people find that not only computers and mobile terminals, but also all kinds of objects in life, as long as they are equipped with chips, they can access the Internet and realize the exchange and transmission of information. For example, previous robotic performances have become today's smartwatches and bracelets.

For example, if a smart chip is installed on the gas meter at home, the gas meter reading can be copied automatically, and there is no need for manual meter reading. All we have to do is pay in App.

Seeing here, you probably know what the Internet of things is, right? Yes, the Internet of things is to install chips on all kinds of devices in production and life, so that they all have the ability to access the Internet, which is the so-called Internet of everything.

Knowing what the Internet of things is, the question comes again: with so many things connected, how does the Internet of things work?

2 the operation mode of the Internet of things Xiaobian takes shared bicycles as an example to briefly introduce the current operation principle of the Internet of things.

Shared bike is a typical application model of the Internet of things, which is composed of users, cloud servers and bikes.

User: the App in the user's phone, to be exact.

Cloud server: a cloud server for bicycle operators to store bikes and user information

Bicycle: the core device is an intelligent lock with a chip in it. The chip is the "brain" of the bike, which makes the bike more intelligent while accessing the network.

The operation of shared bikes can be described by the following simple process:

In the above process, 4G communication is used between the user's mobile phone App and the cloud server, while the cloud server uses GPRS to communicate with the bicycle intelligent lock.

Speaking of which, does anyone wonder how shared bikes power the chips in smart locks?

In the past, electricity was generated by manpower. During the ride, the rider acts as a human flesh generator to charge the bicycle smart lock. So the bicycles used to get more and more tired, and now you know why. (cover your mouth and smile)

Today, bicycles are powered by solar panels, which are located at the base of the basket.

So this basket can not be used indiscriminately, such as the one shown below.

As one of the four new inventions, shared bike is a model of the current application of the Internet of things. Similar to shared bikes, other Internet of things application models are also made up of device objects, cloud servers and App. This App can be installed on a user's smartphone or other mobile device to control and manage device objects. In the shared bike model, GPRS communication is used between the cloud server and the bicycle intelligent lock, but 5G communication is not used. So what will the Internet of things based on 5G look like in the future?

3. Looking forward to the future of the Internet of things, in fact, mMTC (large-scale machine communication), one of the three major application scenarios of 5G, is for the Internet of things. Based on the strong connectivity of the 5G network, 1 million devices can be accessed per square kilometer. Roadside manhole covers, street lights, water meters and other public infrastructure all have the ability to access intelligent management platforms so that they can work together. This is the concept of "smart city".

In the "smart city" scenario, only a small number of maintenance personnel are needed to manage the public facilities of the whole city, which greatly improves the operational efficiency of the city.

Smart city is just a microcosm of the Internet of things, devices in other industries and fields can also access the Internet to achieve scenarios such as smart agriculture, smart home and so on.

In the scene of intelligent agriculture, meteorological data, soil temperature and humidity and other data are collected by sensors. When there is no rain for a long time, it can start the irrigation system automatically; when there are more Rain Water, it can start the drainage system automatically, which can significantly improve the efficiency of agricultural production and operation.

In the future, household appliances and equipment can be centrally managed and controlled through the Internet of things. Imagine the smart home scene: the alarm goes off on time every morning and the electric kettle automatically starts to boil water. After you go out to work, the lights and air conditioners turn off automatically, the washing machine begins to wash clothes, and the floor sweeping robot cleans up. And you can control these smart devices at home at any time through your mobile phone App at work.

Technology changes life. With the rapid development of 5G, big data and artificial intelligence, the Internet of things will flourish and bring earth-shaking changes to our lives. Let's wait and see.

What other applications of the Internet of things have you encountered in your daily life, and what is your imagined life of the Internet of everything? Let's leave a message.
