20 13 at the beginning of the new year, it is known as? The strictest in history? Traffic regulations? Six points for running a yellow light? The regulations of the National People's Congress have aroused the concern and discussion from all walks of life. Under the premise that the new traffic regulations cannot be changed, updating traffic equipment such as signal lights seems to be one of the most direct solutions. In fact, what are these solutions? Smart city? The concept and intelligent transportation concept will involve: roads are no longer so crowded, buildings? Zero? Emissions, one card in hand, all public services can be solved.
So-called? Smart city? With the help of the new generation of information technology such as Internet of Things, cloud computing, decision analysis and optimization, the core systems of urban operation such as people, commerce, transportation, communication, water and energy are integrated, so as to better understand and control urban operation and optimize the use of cities with limited resources.
According to the calculation of the World Bank, the urban development dividend of a city with a population of over one million will increase by 2.5? Three times. Under the background of new urbanization proposed by the central government, smart city construction is actually a new round of extension of new urbanization theme investment. 65438+1October 10, Gu Shengzu, vice chairman of the Internal Affairs and Justice Committee of the National People's Congress, pointed out at the Third China Smart City Conference that with the rapid development of urbanization in China, urbanization has become a new dividend and a new engine of growth, and smart cities are regarded as a good medicine to treat urban diseases. According to the statistics of the Information Research Department of the National Information Center, the total number of cities that have proposed smart city construction in China has reached 154, and the estimated investment scale exceeds1500 million yuan.
Smart city governance? Urban disease?
The concept of smart city has been put forward in China for many years. With the proposal of new urbanization construction in the central government, related industries will usher in huge market opportunities. Among them,? New style? Reflected in the city's intelligence and networking, the town has become a high-quality livable place, specifically involving urban complexes, green buildings, intelligent public infrastructure, water treatment and garbage disposal and other environmental protection undertakings, management information technology and so on. Yang, deputy director of the high-tech department of the Ministry of science and technology, pointed out that at present, some cities in China are developing? Urban disease? More and more prominent, vigorously building smart cities will play an increasingly important role in solving this problem. ? We will continue to promote breakthroughs in key technologies and work with the industry to promote the development and upgrading of smart cities. ?
For the past? Not wise? For example, Guo Wei, a representative of Smart City Service Platform, said: An employee of our company was not originally a Beijing hukou, but was later given a Beijing hukou. However, due to communication problems, it took two and a half years to transfer the account to a child. I hope that through the network environment, we can do things more easily and save time and energy. ?
201212 February, officially released by the Ministry of Housing and Urban-Rural Development? Notice on carrying out the pilot work of national smart cities? At the same time, the Interim Measures for the Pilot Management of National Smart Cities and the Pilot Indicator System of National Smart Cities (Districts and Towns) were issued, in which the latter includes four first-level indicators, namely, safety system and infrastructure, smart construction and livability, smart management and service, and smart industry and economy, involving wireless network coverage, urban public basic database and information security, building energy-saving digital city management, garbage classification and treatment, water supply and drainage and gas system.
According to the picture outlined in the plan, people can choose the best travel route through intelligent transportation system before going to work in the future; When you are sick, you don't have to wait in line at the hospital, but you can enjoy it through the telemedicine system? Family doctor? Medical institutions can manage the health status of each resident within their jurisdiction through electronic health records; Traveling abroad includes panoramic, all-weather and personalized navigation, tour guide, shopping guide, meal guide and entertainment guide, and provides various intelligent travel services. You can know the population density, environmental indicators and early warning of natural disasters in the scenic spot at home.
With the beginning of the national pilot work, one? Smart city? The focus of the industrial feast has been opened. In Zhejiang, Ningbo became the first comprehensive pilot city in the province, and Jiaxing's transportation, medical care and power grid were declared in the province. Smart city? Single pilot project. 20 12, Jiaxing? Smart city? The development plan is clear that Jiaxing will build a digital intelligent building within five years? Smart city? Smart application system involves ten fields: government affairs, people's livelihood, transportation, power grid, health, urban management, culture and education, environmental protection, logistics and tourism.
As? Smart city? For one project, Jiaxing has planned to build a photovoltaic high-tech industrial park with an area of nearly 14.2 square kilometers in Xiuzhou District, which is divided into five functional blocks: R&D base, venture base, rooftop photovoltaic solar high-tech service base, rooftop photovoltaic solar equipment manufacturing base and rooftop photovoltaic solar application service base. The roofs of all buildings will be filled with solar cell semiconductor materials in order to convert solar radiation into electric energy to the maximum extent.
Science and technology to build a smart city
The smallest Beidou dual-system satellite navigation receiving module that can accurately locate, measure speed and time, a robot intelligent navigation system that can assist doctors in orthopedic reset, and a multifunctional customer management platform that can provide e-commerce services and precise marketing. Nowadays, with the support of government investment, the construction of smart cities is growing rapidly, and intelligent transportation, digital urban management, urban safety and medical informatization have become key breakthrough areas. New technologies such as the Internet of Things, cloud computing and the next generation Internet will be widely used, and the level of urban intelligence will continue to improve.
At the 3rd China Smart City Conference, Wu, an academician of China Academy of Engineering, pointed out that smart cities use intelligent computing technology to make the composition and services of key urban infrastructure more intelligent, interconnected and effective. With the construction of smart cities, society will enter? Big data? Time magazine. Judging from the disclosed data, the Twelfth Five-Year Plan? During this period, the total direct investment of more than 320 cities in building smart cities exceeded 300 billion yuan.
As the earliest practice in China? Urban-rural integration? As early as 1984, Shanghai put forward China's first urban economic development strategy. Open urban and rural areas? 、? Urban-rural integration? The concept of. But after three five-year plans, Shanghai's urban-rural integration development? Twelfth Five-Year Plan? The plan points out that suburban urbanization still faces? Factors of production such as talents, industries and markets are slowly gathering? Wait for questions.
Suburban urbanization is not the process of rural to urban, but the internal industrial structure problem. How to rebuild the industrial base is very important. ? Chen Wei, an economic researcher at Shanghai Academy of Social Sciences, said? The core of how to accelerate urbanization in Shanghai suburbs is industrial infrastructure, but even if the manufacturing industry in the central city shrinks and there are services such as finance, the suburbs can't find more suitable complementary industries. ? In fact, this is also a problem of Shanghai's overall industrial transformation. In recent years, with the shrinking of industry, especially manufacturing, there is no obvious motivation for progress in the suburbs of Shanghai.
Last year, Shanghai announced "Shanghai Action Plan for Promoting Smart City Construction 20 1 1-20 13", proposing to speed up the construction of digitalization, networking and intelligence? Smart city? Its specific goal is that by 20 13, the total scale of Shanghai's information industry will reach 1.28 trillion yuan, and the added value of information service industry will account for 6.2% of the city's GDP. In the huge? Smart city? Behind the planning is the consideration of Shanghai policymakers on accelerating urban-rural integration. What are the key words? Integration of production and city? . According to Shanghai Action Plan for Promoting Smart City Construction 20 1 1-20 13, the information infrastructure construction will be transferred from the central city to the suburbs. The first step is to cover all the urbanized areas in the suburbs, and the next step is to cover other areas in the suburbs. ?
How to build wisdom
20 12 On September 28th, the inaugural ceremony of the first smart city industrial technology innovation alliance in China was held in Beijing. At the same time, the White Paper on Smart City Technology (20 12) pointed out that although the current smart city construction in China has a certain foundation, there are still many problems such as lack of unified planning, technical standards, industrial base, legal norms and talent support, and it is facing challenges from all sides.
Xue, a senior researcher at China Investment Consulting, thinks: Smart city? It is a new product of the development of modern society, and it is synonymous with the integration of a new generation of information technologies such as the Internet of Things and cloud computing and various network platforms with the real society. ? Smart city? It is the result of the transformation and upgrading of urban development model, and has built a modern new urban development model that is open, innovative, green and civilized. ?
In the process of building a smart city, for enterprises, due to the uncertain market, implementation still needs a process. At the recent 20 12 China Smart City Summit Forum, Cao Guohui, chief strategy officer of Smart China (Holdings) Co., Ltd. said? The main bottleneck of the promotion of a safe city for many years is that we place too much emphasis on the local construction of the city and neglect the operation, management and service of the later equipment. ?
In the past three years, domestic forums and think tanks have had heated discussions on the development model of smart cities, but there is no real model yet. From the smart city planning issued by local governments at present, we can see that no matter from the regional development, industrial prospects or the support and attention of higher authorities, they all want to embody their own characteristics to the greatest extent.
Because the construction of smart cities involves many fields, the characteristics of different places and the level of economic development are different, there is no unified management system at present. Therefore, the Ministry of Housing and Urban-Rural Development studies the standards of smart cities, hoping to break the information island and realize data sharing and collaboration in smart cities. In the future, we will also plan the construction, service and operation mode of a new generation of smart communities by relying on the interconnection based on the city card and the favorable opportunity of smart city construction.
Yang Xueshan, Vice Minister of the Ministry of Industry and Information Technology, once said that a smart city is the product of the intersection of industrialization, urbanization and informatization at a specific historical moment. Nowadays, the Internet is undergoing earth-shaking changes, and the speed of emerging technologies is also accelerating rapidly. Will smart cities bring another new model, new technology and new application? Fusion? With what? Crossroads.
The result of this integration can not be simply summarized by technological revolution or industrial revolution, but will eventually serve as the keynote and social operation order of the whole era. Technology promotes the progress of the times, and human nature can restrain the madness and impulse of the times, which may be the future value of smart cities.
