"Urban development is inseparable from three-dimensional space and time. Spatiotemporal information is the best reference and the best record of urban development. Li Weisen, deputy director of the National Administration of Surveying, Mapping and Geographic Information, "popularized" the smart city in his eyes from a professional point of view
"Smart city is to rely on modern information technology such as the Internet of Things and cloud computing under the support of spatiotemporal information, solidify human information into the construction, management, operation, service and development of the city, and form an intelligent operation that does not depend on people or rarely relies on people."
Li Weisen believes that the construction of smart cities should start from three aspects: 1. infrastructure construction in hardware, network, transmission and other aspects; 2. Spatiotemporal information infrastructure; 3. Intelligent improvement in various fields and industries.
From digital city to smart city, the National Administration of Surveying, Mapping and Geographic Information currently focuses on four aspects: 1. Rich data, and great enrichment of diversified data; 2. Introduce the time dimension; 3. Technical methods should be improved; 4. Increased intelligence. Li Weisen believes that "whether the construction of smart cities is informatized or intelligent, social geographic information must first go and must be the foundation."
In the specific urban "intelligent" construction, whether a unified set of indicators is needed is still being debated and explored. However, the top-level mechanism of smart city standardization is indispensable in the early stage of construction and promotion.
Yin Minghan, Chief Engineer of the National Standards Committee, said: "Smart city standardization is the basic guarantee for the orderly and healthy development of smart cities, a necessary condition for promoting the aggregation, sharing, development and utilization of urban information resources, and an important support for promoting the effective application of emerging technologies such as cloud computing, Internet of Things, big data, and mobile Internet in smart city construction." ”
Yin Minghan gave reasons for the necessity of standardization: "The architecture of a smart city is a so-called system system, involving information, remote sensing, communication, urban management, and planning and many other fields, which is a complex system engineering, and standardization work needs to effectively use and integrate the standardization basis of various fields." ”
What the National Standards Committee has done in the process of specific promotion is: to build a cross-field and cross-departmental standardization collaboration platform; Established the Smart City Standardization Coordination and Promotion Overall Group and the Expert Advisory Group; From the three levels of expert consultation and decision-making suggestions, standard coordination and division of labor development, in accordance with the overall plan, jointly promote, distribute implementation, and jointly carry out relevant work.
The current progress is: in 2013, the National Standards Committee issued five ideal plans for standard city national standards, covering smart city technology, reference models, evaluation models, unit evaluation systems, and SOA application guidelines and other basic standards.
