Smart City is a new stage in the development of Digital City, a digital city endowed with wisdom. Palmisano Palmisano, CEO of IBM, believes that smart technologies are being applied in all aspects of life, such as smart transportation, smart electricity, smart medical care, and smart infrastructure, and together they form a smart city, which makes the earth more and more intelligent.
Based on the determination of the connotation of smart city, the overall framework of smart city is drawn up as shown in Figure 1, which can be summarized as “information perception and transmission platform, data management and service platform, information sharing and service platform, management and service system, decision support It has six components including service system and operation and maintenance guarantee system. The following are respectively explained:
Smart City Information Perception and Transmission Platform
The information perception and transmission platform mainly includes two parts: information perception facilities and information transmission facilities. Information perception facilities refer to the information collection facilities and technologies located at the front end of the urban informatization system, such as remote sensing technology, radio frequency identification technology (RFID), GPS terminals, sensors and camera video collection terminals and other information collection technologies and equipment.Information transmission facilities mainly refer to wired and wireless network transmission facilities, including communication optical fiber networks, 3G wireless communication networks, WLAN networks in key areas, microsensingNetwork, etc., as well as related servers, network terminal equipment, etc.
Smart City Data Management and Service Platform
The data management and service platform mainly includes two aspects: data integration management and data information service. Data integration management mainly refers to the classification management of database systems that form smart cities with the help of data warehouse technology, involving basic geographic databases, historical databases, resource and environment databases, tourism management-related topic databases, remote sensing image databases, video databases, and application-oriented databases. On the basis of data integration management, with the help of cloud computing technology, data information and computing services can be provided for smart city management and service systems and decision support and service systems through sharing and service platforms.
Smart City Information Sharing and Service Platform
The information sharing and service platform of smart city is a shared service center based on SOA and cloud computing. The city’s operation management and service system and decision support and service system provide technical and information services, which can realize the tasks of information management, process management, application request response, and application service provision of the entire city.
Smart city management and service system
The smart city management and service system includes four aspects: smart government, smart business, smart community, and smart service. Smart government is the further development of e-government, which mainly covers the informatization of government affairs management and the networked urban operation, involving various intelligences such as urban resource management, planning management, environmental protection, tourism operation, etc. Similarly, smart commerce is the intelligentization of e-commerce. Development mainly realizes the informatization of enterprise production management and the networking of business activities; the smart community is the further deepening of the digital community, realizing the informatization of citizens’ daily biochemistry and the networking of behavioral decision-making; smart service is the development of intelligent services for the general public. Service, involving the informatization of popular science education and the networking of information acquisition.
Smart City Decision Support System
The decision support and service system is mainly based on the above four urban management and service systems, combined with expert knowledge, data mining, knowledge discovery, scenario analysis, decision-making models, etc., to make comprehensive decisions on major events in urban management and management. , to provide technical and information support for comprehensive decision-making, to meet the needs of intelligent operation and management of smart cities, and to achieve sustainable urban development.
Smart City Operation and Maintenance Guarantee System
In order to ensure the orderly development of smart city construction, it should be guaranteed in six aspects: policy, mechanism, capital, technology, talent, and safety, establish and improve the operation and maintenance guarantee system for smart city construction, and provide information for city management and services.
