Smart city uses information and communication technology to perceive, analyze and integrate the key information of the core system of urban operation, so as to make intelligent responses to various needs including people's livelihood, environmental protection, public safety, urban services and industrial and commercial activities. Its essence is to use advanced information technology to realize the intelligent management and operation of the city, so as to create a better life for people in the city and promote the harmonious and sustainable growth of the city.
First, the construction of smart cities must focus on the application of information technology. Smart city can be regarded as an advanced stage of urban informatization, which inevitably involves the innovative application of information technology, and information technology is the core and representative of emerging hot technologies such as Internet of Things, cloud computing, mobile Internet and big data.
Secondly, a smart city is a complex interactive system. In this system, information technology and other resource elements are optimized and work together to make the city run more intelligently.
Third, smart city is a new urban development model. Smart cities serve the main body of the city-government, enterprises and individuals. The result is the transformation, promotion and perfection of urban production and lifestyle, which finally shows that human beings have a better urban life.
To sum up, the essence of smart city lies in the high integration of informatization and urbanization, which is a manifestation of the development of urban informatization to a higher stage under the environment of new generation information technology development and knowledge society innovation 2.0.
Specifically, a "smart city" needs to have four characteristics: comprehensive and thorough perception, ubiquitous broadband interconnection, intelligent integrated application and people-oriented sustainable innovation.
Comprehensive and thorough perception:
Through sensing technology, we can realize the monitoring and comprehensive perception of all aspects of urban management. Smart cities use all kinds of sensing devices and intelligent systems to intelligently identify and stereoscopically sense all-round changes of urban environment, state, location and other information anytime and anywhere, fuse, analyze and process the sensing data, and then intelligently integrate with business processes, so as to actively respond, thus promoting the harmonious and efficient operation of key urban systems.
Broadband ubiquitous interconnection:
The development of various broadband wired and wireless network technologies provides basic conditions for the comprehensive interconnection, intercommunication and interaction between things, people and people in cities, and provides basic conditions for all kinds of applications in cities at any time, anywhere, on demand and at will. Broadband Ubiquitous Network, as the "neural network" of smart city, greatly improves the ability of smart city as an adaptive system for information acquisition, real-time feedback and intelligent service anytime and anywhere.
Application of intelligent fusion;
Modern city and its management is an open and complex giant system, and the application of a new generation of comprehensive sensing technology has increased the massive data of the city. Great achievements make wisdom. Based on cloud computing, the storage, calculation and analysis of massive data are realized through the application of intelligent fusion technology, and the comprehensive integration method (comprehensive integration seminar hall) is introduced to greatly improve the decision support ability through the participation of people's "wisdom". Dacheng smart project based on cloud computing platform will constitute the "brain" of smart city. The integration and development of technology will further promote the combination of "cloud" and "terminal", promote the development from personal communication, personal computing to personal manufacturing, promote the intelligent integration of random applications anytime, anywhere, on demand, and further demonstrate the power of personal participation and users.
People-oriented sustainable innovation;
The next generation of innovation facing the knowledge society reshapes the people-oriented connotation of modern science and technology, and also redefines the role of users, the value of application, the connotation of cooperation and the power of the public in innovation. The construction of smart cities pays special attention to people-oriented, citizen participation, social coordination and the creation of public and unique values. Pay attention to citizens' needs, strengthen users' participation through Wiki, Weibo, Fab Lab, Living Lab and other tools and methods, gather public wisdom, and constantly promote users' innovation, open innovation, mass innovation and collaborative innovation, so as to realize people-oriented sustainable economic, social and environmental development.
