Abstract: The process of human development is also a history of continuous pursuit and exploration of a better city life. Pursuing a better urban life and promoting and realizing high-quality urban life are not only problems that developed countries must face up to and solve, but also themes and problems that developing countries need to give priority to in the future and future development. City is the carrier and core of scientific and technological innovation, and the rapid development of science and technology and urban scientific and technological innovation has accelerated the renewal of cities and the promotion of life. In today's information age, with the help of new technology, human beings not only have the ability to better solve all kinds of "diseases" and problems in urban development, but also have the ability to create a new, more dynamic, more attractive and high-quality urban living mode by using scientific and technological innovation, and open up unprecedented new urban time and space for our development and communication, such as smart city, scientific and technological city, historical city, cultural city, information city, green city, healthy city and so on. This paper will focus on the present situation and development prospect of the "smart city" plan.
Text: World Expo is a comprehensive international activity, and its purpose is "understanding, communication, gathering and cooperation". Hosting the World Expo not only strengthened the mutual communication and interaction among countries, but also played a positive role in promoting the peaceful development of science and technology for mankind. This World Expo puts forward "Better City, Better Life" loudly, and discusses the challenges and future development trends of human urban life. It is a symphony with the theme of "innovation" and "integration" and a wonderful dialogue of human civilization. The future urban construction must be based on the sustainable development of human beings, cities and the earth, and science and technology will be the key factor to promote the development of the three.
The "fundamentals" of today's cities are of great benefit to mankind, but in some highly urbanized countries, many "urban diseases" have also appeared, resulting in the trend of "anti-urbanization". Faced with this situation, studying how cities can make human life better has become a big topic with the word "people" as the first priority. At the Shanghai World Expo, countries will show their achievements in building a better city and "making life better", and will also hold various discussions and explore new tricks. The "Smart City" plan put forward by Cisco Pavilion is one of the highlights of this World Expo.
Intelligent city is the embodiment of the diversified characteristics of intelligent building, which is the product of the information age. Its basic elements are networking of communication system, automation and intelligence of office business, flexibility of building and automation of building management service.
"Smart City" relies on the wireless digital integrated service platform, and its network environment includes broadband network, mobile Internet, telephone network, TV network and various wireless networks. , whose services include computing, management, control and resource browsing. Through this comprehensive service platform, "smart city" will provide residents with a convenient and safe living environment, and at the same time provide convenience for the government to manage the city, which will play a great role in saving social resources. Intelligent buildings and smart houses are controlled through the network, and public transportation systems are operated on demand to realize the visual control of energy use and the minimization of carbon dioxide emissions, thus achieving the purpose of energy conservation and environmental protection. The ongoing "Smart City" project in Japan includes the environmental protection technologies of 15 top Japanese high-tech enterprises, and everything in the city is controlled by computers. In the "Smart City" project in Japan, the centralized control device can control the smart buildings and smart houses through the network, run the public transport system on demand, realize the visualization and controllability of energy use, and minimize the emission of carbon dioxide, thus achieving the purpose of energy conservation and environmental protection. In the "Smart City" plan jointly established by SK Telecom and China Railway Second Bureau, the main direction is to provide advanced urban management services, intelligent environmental protection, comprehensive waste recycling, public safety, SK e-sports and digital entertainment in Korea. The joint venture company will first take Chengdu Jinma International Sports City project as a demonstration area, and then provide services to other cities.
During my visit to Cisco Pavilion in the Expo Park, I personally experienced the security and convenience brought by "smart city" and learned how city managers can use "smart" tools to deal with accidents in time, eliminate hidden dangers, cooperate with departments more efficiently and provide more humanized public services. Intelligent transportation will accurately perceive and effectively allocate public resources such as roads and parking lots. Urban roads are no longer congested, and parking is no longer a headache; One-stop online service can create more applications for the public. The "citizen card" will become a city pass. The watch you wear will transmit your blood pressure, pulse and other information to the hospital, and then broadcast the health consultation provided by the doctor. When a thief knocks on the door, your door will automatically give an alarm to the mobile phone of the community security guard ... This fully embodies the smart city concept of "intelligence+interconnection+collaboration".
I have some ideas about smart cities. In some sunny cities, we can try to set up some "solar houses" to apply free energy to every household, which is in line with the environmental protection concept. Looking at the novel and perfect national pavilions with different shapes, I think the future urban buildings should not only be traditional square buildings or circular buildings in the southeast and northwest, but also be innovated and changed according to the field conditions. The outermost layer of the building can be made into a grid like a bird's nest, and the grid can be dense according to different directions, so that the degree of sunlight can be controlled, and its advantages of cooling and heating can be exerted. The grid is light, windproof and earthquake-resistant, and has good lateral stability. And with the rapid development of science and technology, we can apply new materials to real life at any time, so that the city will be smarter and China will be more prosperous!
As the ancient Greek philosopher Aristotle said, "People come to cities to live. People live in cities to live better. " People gather in the city for life; They stayed there to have a good life. People's livelihood is the lower limit of a "good life", and the upper limit of a good life is a variable. 2 1 century is the century of cities, 2 1 century is the era of new cities, and 2 1 century is the era of urbanization economy. We have entered a brand-new era in human history, an era of global urbanization and urban globalization. Under the tide of globalization, with the development of human beings in 2 1 century, cities will participate in the competition as the main body in the global network. Only cities, no national boundaries; Only global cities, no political capital. Whoever rushes to the beach will get new development opportunities, and the promotion of comprehensive competitiveness among cities will be the key to this competition. Through the exhibition of urban development and beautiful life, through the communication, discussion and exchange of themes, we will promote the global urbanization process and the implementation of urban sustainable development strategy, practice the concept of "creating a green city and building a harmonious home", and improve human reflection and re-understanding of urban development and urban life.
Looking forward to the "smart city" plan and a beautiful and happy life.
