Definition of smart city
Smart city (English: smart city) originated in the field of media. It refers to the use of various information technologies or innovative concepts to connect and integrate urban systems and services, so as to improve the efficiency of resource utilization, optimize urban management and services, and improve the quality of life of citizens.
Smart city is an advanced form of urban informatization in which the new generation of information technology is fully applied to all walks of life in the city based on the next generation innovation (Innovation 2.0) of the knowledge society. The deep integration of informatization, industrialization and urbanization is helpful to alleviate the “big city disease”, improve the quality of urbanization, realize fine and dynamic management, and improve the effectiveness of urban management and improve the people’s livelihood of the city Quality of life.
Background of smart city
Smart city often intersects with regional development concepts such as digital city, perceptual City, wireless city, smart city, ecological city, low-carbon city, and even mixes with e-government, intelligent transportation, smart grid and other industrial informatization concepts. The interpretation of the concept of smart city often has different emphasis. Some hold that the key lies in the application of technology, some believe that the key lies in the construction of network, some believe that the key lies in the participation of people, and some hold that the key lies in the effect of wisdom. Some leading cities in the informatization construction of cities emphasize people-oriented and sustainable innovation. In short, wisdom is more than intelligence. Smart city is not only another view of smart city, or the intelligent application of information technology, but also includes the connotation of human intelligent participation, people-oriented and sustainable development. Based on the development of this concept and the summary of regional informatization practice in the world, “smart city in the vision of Innovation 2.0” analyzes the smart city from two aspects of technological development and economic and social development. It emphasizes that smart city is not only the application of new generation information technology such as Internet of things and cloud computing, but also faces knowledge society The methodology application of Innovation 2.0.
Smart city through the Internet of things infrastructure, cloud computing infrastructure, geospatial infrastructure and other new generation of information technology, as well as wiki, social network, Fab Lab, living The application of tools and methods, such as lab, comprehensive integration method, network mobile all media convergence communication terminal, realizes comprehensive and thorough perception, broadband ubiquitous interconnection, intelligent integration application and sustainable innovation characterized by user innovation, open innovation, mass innovation and collaborative innovation. With the rise of network Empire, the integration and development of mobile technology and the democratization process of innovation, smart city under the environment of knowledge society is the advanced form of information city after digital city.
From the perspective of technology development, the construction of smart city requires the realization of comprehensive perception, ubiquitous Internet, pervasive computing and fusion applications through the new generation of information technology applications such as the Internet of things and cloud computing represented by mobile technology. From the perspective of social development, smart city also requires the use of wikis, social networks, Fab Lab and living The application of tools and methods such as lab and comprehensive integration method can realize the sustainable innovation under the knowledge society environment characterized by user innovation, open innovation, mass innovation and collaborative innovation. It emphasizes that the comprehensive and sustainable development of economy, society and environment can be realized through value creation and people-oriented.
In 2010, IBM formally put forward the vision of “smart city”, hoping to contribute to the development of cities in the world. According to IBM’s research, the city is composed of six core systems: Organization (people), business / government affairs, transportation, communication, water and energy, which are related to different types of network, infrastructure and environment. These systems are not fragmented, but are interconnected in a collaborative way. The city itself is a macro system composed of these systems.
The team concluded that: the “smart city” in the 21st century can make full use of information and communication technology to sense, analyze and integrate the key information of urban operation core system, so as to make intelligent response to various needs including people’s livelihood, environmental protection, public safety, urban services, industrial and commercial activities, and create a better urban life for mankind.
