The article mainly discusses the technical basis of smart cities in China, and analyzes the limitations and technical bottlenecks of smart city applications according to China's current environment, and proposes that innovative technology is the key to creating smart cities.
At present, China is in the process of rapid urbanization. The scale of the city is constantly expanding, and it plays a very important role in promoting economic, social and human development and stimulating the overall development level of the country. However, with the increasing pressure on urban environmental protection, energy conservation, transportation, and industrial transformation, new urban development models and management tools are urgently needed to improve urban development. With the rapid development and wide application of information technology, the concept of “smart city†is coming to the fore. More and more cities have proposed to build smart cities as a way of transforming development in the “Twelfth Five-Year Planâ€, so the future construction of smart cities will set off a new wave of climax in China. As a perfect combination of information technology and urban construction, smart cities involve many technologies. The article mainly discusses the technical basis of smart cities in China, and analyzes the limitations and technical bottlenecks of smart city applications according to China's current environment, and proposes that innovative technology is the key to creating smart cities.
The accumulation of cultural material and the advancement of science and technology are gradually evolving along with the city, and the driving force of urban development has gradually turned into the result of wisdom, that is, the masses of people can enjoy the services and products brought by innovative technology without interruption. At present, the construction of smart cities has been valued by the state and vigorously promoted by various governments. More and more smart cities will be presented to the public. The so-called smart cities refer to the scientific and rational urban development concept, according to the latest generation. Information technology, on the basis of ubiquitous Internet and comprehensive information perception, realizes intelligent self-perception and self-optimization of seamless connection and collaborative linkage between people, things and urban functional systems, thus improving people's livelihood, environmental protection, public safety and urban functions. Business needs, such as business activities, respond intelligently, forming a safe, convenient, high-school, green urban form with sustainable endogenous power. The smart city realizes the optimization and upgrading of the urban system, making the urban system perfect, smarter, more coordinated and more developed, making the people and things in the city smarter and more harmonious, and making the life of the people in the city happier.
1 Three technical foundations of smart cities
The construction of a smart city requires the combination of technological innovation, public awareness, and government management, and technological innovation is the cornerstone of building a smart city. “Information†is the core of wisdom, so “information technology†is the core technology that supports smart cities.
1.1 Extensive communication technology allows smart cities to have a nervous system
When a person wants to transmit all kinds of information that he sees, hears, and touches to the brain, he needs a nervous system all over the body. For a smart city, having such a nervous system is the most fundamental requirement for achieving wisdom. The ubiquitous communication network is like the nervous system of the city. Only with it can information be accessible.
1.2 The popularity of Internet technology has made the ability of wisdom close to the ordinary people.
Before the Internet technology, information processing was only a matter of large computer equipment gathered in a few dedicated computer rooms, and had little to do with ordinary people. Although the information can be transmitted, the scope of information transmission is very limited, and it is far from reaching the end of the city. Internet technology fundamentally changes the way humans acquire and process information, so that any ordinary people can access and generate information at will. The ability to be intelligent is only close to the ordinary people, and a smart city can be realized.
1.3 The development of embedded technology, the ability to expand the ability to expand
From a technical perspective, “smart city†is a city information system based on network information. The difference in intelligence ability comes from the difference in information acquisition ability. Smart cities not only need more people to acquire and generate information at any time. The infrastructure in the city also needs to be able to automatically collect and dynamically monitor information. From a technical point of view, it is the ability of various devices to have independent computing and networking. The development of embedded technology makes this possible. Therefore, embedded technology is one of the technical foundations of smart cities, and it enables the ability of wisdom. Expand from people to items.
2 Application limitations and technical bottlenecks in smart cities
2.1 Smart City Application Limitations
Most of the current smart city applications are simple scenarios for handling data collection and data transmission. Although there are certain areas in simple data collection and data transmission modes, they cannot cope with some complicated fields. In our real world, there are still many complicated situations that require different types of nodes to cooperate in the application field of intelligent computing. Moreover, these simple data collection and data transmission can only be limited to areas where data security, real-time and reliability are not high. In the event of data theft, tampering, etc., it will not cause much serious consequence. However, for some data errors, losses, delays, areas that will cause significant losses, such as: medical surgery control, train traffic control, large-scale mechanical equipment operation control, etc., due to constraints, such areas of the Internet of Things have not yet touched .
