Smart city is one of the main directions of urban development in the new era. It will play a leading role in promoting urban modernization, building a livable city and improving urban governance efficiency. According to the requirements of the 14th five year plan for the development of urbanization in Sichuan, cities and towns at all levels urgently need digital empowerment, especially to build an efficient and comfortable smart city circle. It should be noted that the smart city development model should not be treated only as a technical problem in which ICTs (information and communication technology) are embedded in the city. More importantly, the embedding process of ICTs should be regarded as a part of the development of urban economy, society, culture and environment. The urban innovation system, knowledge production institutions, serving urban residents and efficient governance of the city should be formed into a “service group” to build a service future Sichuan smart city circle with continuously upgraded version mode.

Based on the Internet and big data as the engine

Build a Cloud City

Strengthen the investment in intelligent terminal embedded platform and build a seamless urban network. The early version of smart city emphasizes that urban residents can embed urban intelligent network system anytime and anywhere. However, the practice in reality is to build some fixed intelligent terminal platforms, urban wireless networks (WiFi) and other primary facilities, without considering that the most fundamental problem is that urban residents are the main body of continuous movement, and it is difficult for cities to fully keep up with the pace and frequency of people’s movement in the construction of fixed intelligent terminal facilities. Therefore, we often lament that there are always places in the city where it is impossible or inconvenient to use smart terminals, or even if one smart terminal (such as mobile phone) can not be embedded into the urban smart network system in real time. Obviously, our investment and construction of smart city intelligent terminals or access platforms need to be strengthened, and the access and terminal construction of urban seamless intelligent network services must keep up as much as possible.

Use data to lay the foundation for cloud transfer and promote the upgrading of urban capacity. The rapid development of information technology has provided technical support for the realization of smart city and expanded the urban capacity. Many services that cannot be accommodated by traditional urban infrastructure construction have been transferred to online, especially the cloud. This construction mode breaks the barrier of untimely communication of traditional urban planning information, and realizes dynamic and flexible urban planning and construction. By establishing a unified urban cloud data platform, formulating unified standards, and combining the analysis of economic, social and environmental data, we can accurately predict the development trend of the city, dynamically adjust the construction objectives and service levels of urban planning, and move as many offline commodity transactions, e-government, data transmission, interpersonal communication, business travel, foreign trade, financial investment, education and medical treatment, urban governance and public service activities as possible to the cloud, Reorganize, match and even simulate some urban development issues, factor use methods and metropolitan area development modes that cannot be accommodated or practiced offline in the cloud. The cloud urban spatial structure, industrial structure, public service model, urban social governance analysis and the economic and social relations and data formed and collected in urban cloud social networking can provide support for in-depth analysis of the mutual flow relationship and functional restriction relationship of various elements within the city, formulate scientific and reasonable planning strategies for offline urban planning and design, and expand the resource capacity of urban development.

Therefore, in combination with the national development strategy of computing from the east to the west, we should break through many core technologies involved in the cloud construction of smart cities, make them take the Internet as the basic platform, big data as the engine, realize the operation of urban digital informatization through practical technologies such as cloud computing, supercomputing and the Internet of things, build the city into a digital three-dimensional cloud platform, and especially carry out the comprehensive test of urbanization in combination with the construction of the twin city economic circle in Chengdu and Chongqing, On the basis of the basic co urbanization development of transportation infrastructure, we might as well test the co urbanization of cloud cities and open a new pattern of coordinated development of cloud cities. The operation of the above technologies is based on big data, so the necessity and scarcity of data as a factor of production are becoming more and more prominent. It is suggested that all localities should plan data exchanges and big data computing centers as soon as possible, so as to lay the foundation for the rational, efficient and market-oriented use of data in Yuncheng City in the future.

Build a network urban community and carry out digital collaborative governance. The development of smart city should attach great importance to the collaborative governance ability of communities. However, traditional communities are limited by geographical location, epidemic prevention and control, population size, development level and supporting facilities. The governance modes are quite different, which makes it more difficult to carry out the collaborative development of urbanization. The online urban community can break the above restrictions, enable citizens to actively participate in digital inclusive community transformation activities, establish an online community credit system, and integrate the network, innovation and cooperation, which is very conducive to building an innovation center and innovation culture based on the online urban community.

In this way, new smart city innovation projects based on online urban communities will be constantly spawned. For example, digital media center, culture, tourism, digital entertainment incubation and training, it Resource Center, Cyberport, cooperative design and development, etc. are all new smart city development projects that can be expected and the Digital Collaborative Governance model of metropolitan area, which is very important for meeting the needs of urban residents’ learning The need of knowledge transfer and capability construction provides a new wisdom space and cooperation mode.

Comprehensive interconnection of people, machines, networks and cities

Building a future city metaverse

Metaverse (metaverse) recently discussed by the international and domestic Smart City academic circles, that is, Quanzhen Internet and super digital scene, essentially refers to the Internet form connecting time and space in the future, or a commercial expression of time and space Internet after connecting people’s mobile Internet and things. It is undeniable to focus on the complexity of the current urban development, but it is only a controversial issue to focus on the application of metaverse technology in the future.

Among them, multiple urban systems interweave and interact with each other, especially after adding complex variables such as “human” and “society”, they have become a huge social physical information system, and metaverse may be the next generation artificial intelligence urban model that is compatible with and promotes these systems. The description of its running state needs more complex systems such as “flow, field and network” than three-dimensional solid space, as well as the randomness and emergence of information or resources. For example, people’s Park teahouse, Kuanzhai alley shopping and Xinglong Lake running, which are common in offline urban life, can not only be integrated in time and space, but also be integrated into a new business experience model in urban metaverse. Relevant information and resources are no longer linear and subject to time and space constraints. Therefore, metaverse may be a new expansion of urban digital space, allowing people to have a more holographic and original experience in digital space. We have initially reached the threshold of this concept and technology. If we take this as an experiment in the next smart city, it may push us to an era inflection point of switching the relationship between physical space and digital space. Digital space will no longer be a copy of physical space, but an equal and even more important and broad new field.

Obviously, in the future, life, work and entertainment in smart cities will become more and more integrated, and the boundaries between them will gradually blur. The construction of smart city should make full use of the basic capabilities of digital twinning, communication and AI as soon as possible to make people machine network city integrated. The digital transformation of this urban system needs to improve the analog computing capacity of the urban system, build a new digital city access mode, and enable citizens and stakeholders to participate in the decision-making process of urban operation in various ways through the comprehensive interconnection of people machine network city, Using human intelligence to make up for the intelligence of machines may be a shortcut for cities to realize real wisdom. For example, in the floods in Henan and Shanxi in 2021, citizens used online documents to quickly establish a list of rescue needs, so as to realize the rapid docking of resources and the matching of supply and demand. At the same time, the relevant online applet also released the “flood control mutual assistance information sharing service” within a few hours, which can release help information based on maps, and introduced relevant subjects such as emergency response and rescue of governments at all levels. With the technical support of smart city, accurate and timely supply and demand information supported hundreds of government and private rescue teams to save the lives and injuries and work efficiently in the days after the disaster, minimizing the loss of people’s lives and property. This kind of smart city application is only the beginning at present. The future construction will also reflect more inclusive service capabilities and demonstration and leading functions of smart digital cities. Its prospect can lead the innovation of urbanization development model in Sichuan.
