A smart city refers to the comprehensive use of advanced information technologies such as the Internet of Things and cloud computing to sense, analyze, and integrate key information in urban operations. By providing intelligent services, it makes urban management and services more effective, and provides an environment for harmonious coexistence between people and society, people and people, and people and things for urban business activities and citizens. Smart cities are the product of a new round of information technology revolution and further development of the knowledge economy. They are an inevitable trend of deep integration of industrialization, urbanization, and informatization. They are an effective way to comprehensively solve "urban diseases" and a sustainable urban development model.

The construction goal of a smart city is to fully utilize technological innovation, lead urban development with "intelligence", and create a city that is environmentally friendly, ecologically livable, with healthy industrial development, efficient government administration, and a happy life for citizens. On the basis of urban informatization, the new generation of information technology has further penetrated into various fields of urban operation, forming a comprehensive perception, extensive interconnection, and collaborative organic network.

Smart city construction is the comprehensive application of new generation information technology on the existing urban infrastructure, endowing the infrastructure with interactive capabilities, recognizing objects, sensing the basic operation of the city, and achieving information transmission between objects; And the information obtained from interactive perception is uniformly managed and scheduled through cloud computing platforms. Relevant departments in the city extract information according to their needs for intelligent processing, analysis, and prediction, forming various system solutions: intelligent traffic management system, medical information system, intelligent security management system, intelligent energy management system, water quality and environmental monitoring system, intelligent campus management system, mobile office management system, intelligent ticketing management system Virtual tourism management system, etc; By creating a unified urban operation command center, we provide efficient urban management tools and approaches for urban managers, thereby providing high-quality services and broad innovation space for enterprises, and providing better quality of life for citizens.
