This article mainly explains "what are the basic knowledge of the Internet of things". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought. Let's study and learn "what are the basic knowledge of the Internet of things"?

First, do you know the artifact of long-distance love-- "spaced kissing machine"?

As the lowest educated member of the Big Bang Theory quartet, Howard relies on his rich facial expressions, yelling at his mother and all kinds of crooked ideas to maintain his status in the eyes of the audience. Serious inventions are impossible, not for the rest of your life. As one of his "brains", the "interspace kissing machine" can be said to be the most practical invention! By placing two sensors on two mouth-like devices, and then touching one of the devices with your mouth, the other can feel the touch of the other's lips. Although a little bit. But it really works! After all, Leonard is not yet a trial of oral integrity, and then he and his Indian girlfriend become the first beneficiaries.

As an artifact of long-distance love, the "spaced kissing machine" perfectly embodies the concept of the Internet of things: the client extends and extends to the connection between things and people on the basis of the Internet. In the Internet of things mode, all objects are connected to the network, and communicate and interact with the scene.

More technically, the Internet of things is an extension of the Internet. The Internet connects participants through computers, mobile terminals and other devices, forming a new way of information exchange. The Internet of things connects devices through sensors, chips and wireless modules. Therefore, the number of device connections to the Internet of things is very huge, because in theory, all devices can be connected to the Internet.

Second, the three elements of the Internet of things: what should a complete Internet of things look like?

Although Howard's "interspace kissing machine" is a good interpretation of the prototype of the Internet of things, it cannot be said to be a complete Internet of things. Because the formation and control of the Internet of things depends on the following three elements.

Equipment networking capability: through different network protocols and communication standards, realize the connection between the equipment and the control terminal, and perform intelligent operation.

Cloud: provide monitoring, storage, analysis and other data services, as well as ensure the security of customers' business data.

Control side: receives data information and control instructions from devices and clouds. The control side is usually App, cloud intelligence, and other devices (such as Google Home,Amazon Echo, etc.).

The "spaced kissing machine" only initially realizes the networking ability of the equipment, allowing two people in different spaces to realize tactile interaction based on sensors. Let's assume a scenario if the "interspace kissing machine" can be mass produced (congratulations on the sale of Howard products here! Howard will need a cloud to store and analyze all terminal devices (such as geographic location, power consumption, temperature and humidity, and so on). As a user, out of the pursuit of product capability, in addition to the basic requirement that the product can be more beautiful, but also need to have panel or voice and other control functions, in order to be able to control the equipment more accurately.

3. DCM architecture of the Internet of things: Device, Connect, Manage

In the system architecture of the Internet of things, it can be divided into three logical levels of DCM (as shown in the following figure).

Perception layer (Device): belongs to the first layer of DCM architecture, responsible for comprehensive perception, the use of radio frequency identification, QR code, sensors and other sensing, capture, measurement technology to collect and obtain information on objects anytime and anywhere. That is, the equipment terminal of the "spaced kissing machine".

Network layer (Connect): responsible for reliable transmission, by connecting objects to the information network, relying on communication networks and protocols to achieve reliable information exchange and sharing. That is, the data stored in the "spaced kissing machine" and "after mass production"

Application layer (Manage): responsible for intelligent processing, analysis and processing of massive perceptual data and information, to achieve intelligent decision-making and control.

IV. General situation of the industry: the global Internet of things is "advancing by leaps and bounds" and AI+IoT integration has landed.

The number of connections is advancing by leaps and bounds.

The concept of AIoT emerged in 2018. According to the industry research report of iResearch Consulting, it is estimated that there will be nearly 20 billion Internet of things connections in China in 2025. The awakening of everything and massive connections will promote various industries to embark on the smart road.

According to the international data and information IDC, the Internet of things will generate a global value of US $1.46 trillion by 2020.

The Development of 5G Technology with the coexistence of fanaticism and prudence

5G technology is one of the hot topics in 2019. In 2019, the Ministry of Industry and Information Technology issued a temporary business license for 5G, marking the beginning of the first year of 5G.

According to the work progress of the standards organization 3GPP, the completed 5G standards are mainly focused on enhanced Mobile Broadband (eMBB) scenarios. From 2019 to 2020, 5G took the lead in commercial scenarios, but the eMBB scenario is more used in the mobile Internet, still dominated by human-to-human communication, and limited support for Internet of things applications. The standardization of low latency and high reliability (uRLLC) and large-scale machine communication (mMTC) in the other two scenarios is still not completed, and their commercial progress will be slower, and the technology of these two scenarios is the core support of 5G used in the business field of the Internet of things.

Cloud, edge and end collaboration, AI and Internet of things convergence further landing

In the application scheme of the Internet of things, cloud computing, terminal computing and edge computing are a collaborative system, which is dynamically configured according to user scenarios, resource constraints, real-time business and so on, to form a reliable and low-cost application scheme. Different roles such as cloud computing vendors, IT vendors, operators and vertical industry vendors have different understandings of the concept of edge computing, edge node location and edge computing power, but they have reached a consensus to achieve cloud, edge and end collaboration in the Internet of things solution.

Judging from the development and accumulation in the past few years, AI has been integrated at many levels of the Internet of things, and the capability architectures of AI on the terminal side, AI on the edge side and AI in the cloud are all available. Some well-known Chinese enterprises, such as Haekangwei, Lazio Technology, Horizon and so on, have released Internet of things-related platforms and products, hoping to achieve more business expansion through AI+IoT.
