What is the relationship between the Internet of Things and the Internet, when will the explosion occur and what are their uses?

Name Explanation

The Internet of Things is an important part of the new generation of information technology and an important development stage in the "informatization" era. Its English name is: "Internet of things (IoT)".

As the name suggests, the Internet of Things is an Internet that connects everything. This has two meanings: first, the core and foundation of the Internet of Things is still the Internet, and it is an extended and expanded network based on the Internet; second, its user end extends and expands to any object to exchange information and communicate, that is, everything communicates with each other.

The Internet of Things is widely used in the integration of networks through intelligent perception, recognition technology, ubiquitous computing and other communication perception technologies. Therefore, it is called the third wave of the development of the world's information industry after computers and the Internet. The Internet of Things is the application extension of the Internet. Rather than saying that the Internet of Things is a network, it is better to say that the Internet of Things is 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.

definition

The concept of the Internet of Things first appeared in Bill Gates' 1995 book "The Road Ahead". In "The Road Ahead", Bill Gates mentioned the concept of Internet of Things, but it was limited by the development of wireless networks, hardware and sensor equipment at that time and did not attract the attention of the world.

Four categories

In fact, the concept of the Internet of Things comes from the analogy of the Internet. According to the relationship between the Internet of Things and the Internet, different experts and scholars have given their own definitions of the Internet of Things, which can be summarized into the following four types:

1. The Internet of Things is a sensor network, not connected to the Internet

Some experts believe that the Internet of Things is a sensor network, which is just installing sensors on objects in people's living environment. These sensors can better help us understand the environment. This sensor network is not connected to the Internet. For example, the sensor network of Shanghai Pudong Airport is not connected to the Internet, but it is called the first Internet of Things. The relationship between the Internet of Things and the Internet is that they are two relatively independent networks.

2. The Internet of Things is part of the Internet

The Internet of Things is not a brand new network. In fact, it has already existed. It is a natural extension and expansion of the Internet and a part of it. The Internet is an all-inclusive network, and more objects will be added to it. In other words, the Internet of Things is included in the Internet.

3. The Internet of Things is a complementary network to the Internet

The Internet we usually refer to is a global network formed by computers between people, which serves the information exchange between people. The main body of the Internet of Things is a variety of objects, which transmit information between objects to achieve the ultimate purpose of serving people. The main body of the two networks is different. Therefore, the Internet of Things is an extension and supplement of the Internet. The Internet of Things and the Internet are two relatively equal networks. If the Internet is compared to the artery of human information exchange, then the Internet of Things is the capillary. The two are interconnected and are a beneficial supplement to the Internet.

4. The Internet of Things is the Internet of the future

From a macroscopic perspective, the future Internet of Things will put people in an omnipresent network. Without realizing it, people can exchange information with people or things around them anytime and anywhere. At this time, the Internet of Things is equivalent to the ubiquitous network, or the Internet of the future. The Internet of Things, the ubiquitous network, and the Internet of the future, although their names are different, they all express the same vision, that is, humans can use any network, contact anyone or anything at any time, anywhere, to achieve the freedom of information exchange.

The definitions of the four concepts all have their merits and shortcomings. From a narrow perspective, as long as objects are connected through a sensor network, whether or not they are connected to the Internet, they should be considered as part of the Internet of Things. From a broad perspective, the Internet of Things is not only limited to information transmission between objects, but will also be seamlessly integrated with existing telecommunications networks, ultimately forming an omnipresent information exchange between people and objects, and forming a ubiquitous network.

In fact, the relationship between the Internet of Things and the Internet is that they are two relatively independent networks, but they have certain commonalities in data transmission technology. In telephone network and Internet applications, we hope that all people, computers, etc. are interconnected. However, the Internet of Things is different. A Taihu Lake water quality monitoring system and a Sinopec logistics system can have nothing to do with each other. This is why IBM emphasized its vertical industry applications when it proposed the concept of smart earth. Therefore, the Internet of Things is a general term for unconnected dedicated networks based on controllable and manageable technologies for objects. At present, it is accustomed to being called "ubiquitous network" internationally, which is actually to distinguish it from the Internet.

The development of the Internet of Things in China

The rapid rise of the Internet of Things in China is due to our country's several major advantages in the field of Internet of Things.

***, my country started the research on the core sensor network technology of the Internet of Things as early as 1999, and its R&D level is at the forefront of the world;

Second, in the field of sensor networks worldwide, my country is one of the countries with leading standards and has a high number of patents;

Third, my country is one of the countries that can realize the complete industrial chain of the Internet of Things;

Fourth, my country's wireless communication network and broadband coverage are high, providing solid infrastructure support for the development of the Internet of Things;

Fifth, my country has become the world's second largest economy and has relatively strong economic strength to support the development of the Internet of Things.

Application

The Internet of Things has a wide range of uses, covering smart transportation, environmental protection, government work, public safety, safe homes, smart fire protection, industrial monitoring, environmental monitoring, street lighting control, landscape lighting control, building lighting control, square lighting control, elderly care, personal health, flower cultivation, water system monitoring, food traceability, enemy reconnaissance and intelligence gathering and many other fields.
