What is a smart city?

Smart city is a comprehensive application framework that uses information processing methods and technologies such as the Internet, Internet of Things, artificial intelligence, cloud computing, and blockchain to solve various intractable diseases in human society and urban construction.

Smart city is a cross-border field. It is based on information processing methods and technologies such as the Internet, Internet of Things, artificial intelligence, cloud computing, and blockchain. It aims to solve practical problems in various industries and people's lives, and to improve people's lives. The goal is to improve the environment and quality of life, improve the production efficiency of various industries, and reduce costs.

How to understand smart city?

Smart cities are designed to solve real problems.

This must be understood to accurately understand smart cities.

Therefore, a smart city is not as mysterious and out of reach as many people think. On the contrary, smart cities are very practical and practical, and they are related to the big and small things of each of us.

Why do we need smart cities?

In the history of mankind, the development of science and technology has never been as fast as in recent decades, especially the development of the Internet in the past two decades, which is almost changing with each passing day. But relatively, the application of new technologies requires a process, and individual technologies often have limited applications.

When the network and information technology, methods and theories are relatively mature, it becomes the general trend to fully apply them to actual production and life.

But, now, this time has come.

A smart city is a method, a tool, and a way of thinking. It rejects the inherent rules and problems of the past and present. Look at the current world with a new perspective and thinking, and find and solve problems from it. Finally, let us have higher production efficiency and better quality of life.

What does a smart city do?

Give a few examples and be specific.

Let me talk about the relatively simple smart parking first.

Now, there are a lot of smart parking, and I believe many people are using it in their lives. It's just that the degree of "intelligence" can vary a lot.

From the perspective of the driver alone, what should the ideal parking experience be like? Come whenever you want, and you can stop when you come. The place where you park is very close to where you want to go. You can leave when you want. After you leave, the fee will be settled automatically. Anyway, there is no damn pole in the whole process, and there is no time when you can't find a parking space.

So what are the problems to be solved in order to do this? Different types of parking lots will have different problems. For a small parking lot on the roadside, the main problems are vehicle identification and fee settlement. For large parking lots, it is much more complicated, involving parking space matching, vehicle guidance, etc. problems, problems of vehicle parking demand identification, etc.

Let’s talk about a more complicated smart park.

For many large industrial parks, a big problem is that each enterprise in the industrial park has a lot of idle equipment and resources, and idle means waste. Therefore, how to maximize the utilization of these idle equipment and resources has become a very important aspect for enterprises to reduce costs and increase profits. To achieve this, big data and artificial intelligence must be used to rationally and automatically schedule these devices and resources. This involves various issues.

Terminal, cloud, network, intelligence and application of smart city

End: terminal hardware (mobile phone, smart home, smart car, virtual reality, smart wear, drone, robot, large screen, laser projection, etc.)
Cloud: cloud computing
Internet: IoT, 5G, Blockchain
Wisdom: artificial intelligence
Application: Wisdom XX

The terminal is the terminal and terminal hardware.

Including: smartphones, smart homes, smart cars, virtual reality hardware, smart wearables, drones, robots, large screens, laser projection equipment, etc.
When we come into contact with smart cities, we mainly come into contact with these terminal devices and the programs running on these terminal devices.
The terminal is a necessary way for people to interact with the system.

The cloud is cloud computing.

Smart cities cannot avoid huge computing power, huge data processing, unified scheduling and management, and the collaborative work of a large number of terminals. These are difficult to achieve purely by the terminal.
Cloud computing is the necessary infrastructure for smart cities.

The net is the network.

One of the foundations of a smart city is the Internet of Things. The interconnection of a large number of hardware and terminals is one of the characteristics of a smart city. Only on the basis of the Internet of Things can smart city applications be realized.
5G, without 5G, without high-speed wireless network speed, the Internet of Things will be greatly restricted, and most application scenarios of virtual reality can only be a dream. Smart city development will also be extremely limited.
Blockchain, blockchain has two points that cannot be replaced for smart cities.
One is security. A large number of hardware is connected to the network, without blockchain, security issues are a nightmare.
The other is computing power. Although cloud computing can provide powerful computing power, for applications such as smart cities that involve huge amounts of data processing, the current cloud computing based on central computing still has its boundaries in terms of computing power. The blockchain can solve this problem very well.
Perhaps, in the future, blockchain + cloud computing will be a good choice to solve the computing power required by smart cities.

Wisdom is artificial intelligence.

Without artificial intelligence, there would be no smart city. Only artificial intelligence can handle the huge data of smart cities and realize various applications.

Applications are smart city applications.

A smart city application is an application that solves a problem in a city.
Smart communities, smart airports, smart transportation, etc. are all smart city applications.
Of course, this is a relatively large application at present. In the future, there should be smart city applications that focus on one point like smart parking.
This direction is also likely to become the direction of a large number of entrepreneurial enterprises in the future.
