Technology to build? Smart City?

The beginning of the new year 2013, known as ? the strictest ever? Traffic laws and regulations regarding? The first time I saw a yellow light, I was able to get six points. s regulations have sparked concern and discussion in the community. In the new traffic regulations can not be changed under the premise of updating the signal lights and other traffic equipment seems to become one of the most direct way to solve the problem. In fact, these solutions are exactly what? Smart City? concept and the concept of intelligent transportation will involve: roads are less congested, buildings? Zero? emissions, and all public **** services can be solved with one card in hand.

The so-called? Smart City? , is a city that integrates the various core systems of urban operations, such as people, commerce, transportation, communications, water and energy, with the help of a new generation of information technologies such as the Internet of Things (IoT), cloud computing, and decision analytics optimization to better understand and control urban operations and optimize the use of limited resources.

According to World Bank calculations, smart management of a city with more than a million people will increase the urban development dividend by 2.5?3 times. In the context of the new urbanization proposed by the central government, the construction of smart cities is actually a new round of extension of the theme of new urbanization investment. on January 10, Koo Shengchou, vice chairman of the NPC Internal and Judicial Affairs Committee, pointed out in the third China Smart Cities Conference that, as the construction of China's urbanization enters into a period of high-speed development, urbanization has become a new dividend of development and a new engine of growth, and the smart city is regarded as the cure for urban diseases. The smart city is regarded as a good medicine for curing urban diseases. According to the National Information Center Informatization Research Department, the total number of cities in China that have proposed the construction of smart cities has reached 154, and the scale of investment is expected to exceed 150 million yuan.

Smart city cure? Urban disease?

The concept of smart city has been put forward for many years in China, and with the proposal of the central new urbanization construction, the related industry will usher in a huge market opportunity. Among them, ? new? embodied in the city intelligent, networked, so that the town becomes a livable place with high quality, specifically involving urban complexes, green buildings, intelligent public **** infrastructure, water treatment and waste treatment type of environmental protection business, management information technology. Yang Xianwu, deputy director of the Ministry of Science and Technology's high-tech division, pointed out that at present, some of China's urban development? Urban disease? is becoming more and more prominent, vigorously building smart cities will play an increasingly important role in the process of solving this problem.? We will continue to promote key technology breakthroughs, and the industry together to promote the development and upgrading of smart cities.?

For the past?

In the past, the smart city service platform construction was not a smart city. Our company has an employee was not Beijing account, and later to solve the Beijing account, but to the child for the transfer of household registration, because of information communication and other issues, spent two and a half years. We hope that through the networked environment, we can do things more easily and save both time and energy.

In December 2012, the Ministry of Housing and Construction officially released? Notice on the National Smart City Pilot Work? and at the same time issued the National Smart City Pilot Interim Management Measures and the National Smart City (District, Town) Pilot Indicator System, the latter of which includes four first-level indicators for the safeguard system and infrastructure, smart construction and livability, smart management and services, and smart industry and economy, which involves wireless network coverage, the basic urban public **** database and information security, digitalized city management of building energy efficiency, garbage classification and treatment, water supply, drainage and gas system, innovation input, industrial elements gathering, traditional industry transformation and high-tech industry.

According to the picture outlined in the plan, in the future, people can go to work before the intelligent transportation system to choose the best travel routes; sick and then do not have to run to the hospital queue, can be enjoyed through the telemedicine system? Family doctor? The diagnosis and treatment, medical institutions through the electronic health records throughout the management of the jurisdiction of each resident's health status; travel, panoramic, all-weather, personalized navigation, tour guides, shopping guides, dining guides, guide entertainment, to provide a variety of intelligent tourism services, at home you can understand the scenic area crowd density, environmental indicators, natural disaster information warning?

With the launch of the national pilot program, an effort to ?

With the launch of the national pilot program, a smart city? as the focus of the industrial feast has been opened. In Zhejiang, Ningbo became the first comprehensive pilot city in the province, Jiaxing's transportation, health care and power grids were declared the province's ? Smart Cities? In 2012, the "Jiaxing City? Smart City? Development Plan" made it clear that Jiaxing would spend five years to build a digitized and intelligent city. Smart City?

As? Smart City? One of the projects, at present, Jiaxing City has planned and constructed a nearly 14.2 square kilometers of photovoltaic high-tech industrial park in Xiuzhou District, which is divided into five functional blocks: research and development base, entrepreneurial base, rooftop photovoltaic solar energy high-tech service base, rooftop photovoltaic solar energy equipment manufacturing base, and rooftop photovoltaic solar energy application service base. All building roofs will be filled with solar cell semiconductor materials in order to maximize the conversion of solar radiation into electricity.

Technology to build a smart city

Can be high-precision positioning, speed measurement, timing of the smallest Beidou dual-system satellite navigation receiver module, can assist the doctor to implement orthopedic reset robot intelligent navigation system, can provide e-commerce services and precision marketing multi-functional customer management platform? Today, the construction of smart cities is growing at a high rate under the auspices of government investment, intelligent transportation, digital city management, urban security, medical informatization and other key breakthrough areas, the Internet of Things, cloud computing, next-generation Internet and other new technologies will be widely used, the level of urban intelligence will continue to improve.

In the third China Smart City Conference, Wu Hequan, academician of the Chinese Academy of Engineering, pointed out that the smart city is the use of intelligent computing technology to make the composition of the city's key infrastructure and services more intelligent, interconnected and effective, with the construction of the smart city, the society will step into ? Big Data? era. From the disclosed data,? Twelfth Five-Year Plan period, more than 320 cities in the construction of smart cities on the direct investment totaled more than 300 billion yuan.

As China's earliest practitioner of?

Suburban urbanization, not the process of rural-urban landscape, but the inherent problem of industrial structure, how to reconstruct the industrial base is very important. Chen Wei, economic researcher at the Shanghai Academy of Social Sciences, said: ? How to accelerate urbanization in the suburbs of Shanghai, the core or industrial base construction, but the central city even if the manufacturing industry shrinks there are financial and other services support, while the suburbs can not find more appropriate complementary industries. In fact, this is also the overall industrial transformation of Shanghai. In recent years with the shrinking of industry, especially manufacturing, there is no obvious impetus for progress in the suburbs of Shanghai.

Last year, Shanghai announced "Shanghai to promote the construction of smart city 2011-2013 action plan", proposed to accelerate the construction of digital, networked, intelligent as the main characteristics of the ? Smart City? In the huge Smart City? Behind the program is the Shanghai decision-makers to speed up the integration of urban and rural areas, the key word is? The keyword is "integration of industry and city". According to the Shanghai Municipality to Promote the Construction of Smart City 2011-2013 Action Plan, information infrastructure construction will be transferred from the central city to the suburbs,? The first step is to fully cover the urbanized areas in the suburbs, and the next step is the rest of the suburbs.?

How to build wisdom

September 28, 2012, China's first smart city industry technology innovation alliance founding ceremony was held in Beijing, where at the same time the release of the "White Paper on Smart City Technology (2012)" pointed out that, although China's smart city construction has a certain foundation, but there is still a lack of unified planning, technical standards, industrial base, legal norms and human resources support and many other issues, facing a number of challenges. and talent support and many other issues, facing challenges from all sides.

Xue Shengwen, a senior researcher at China Investment Advisor, believes that: ? Smart City? is a new product of the development of modern society, is the Internet of Things, cloud computing and other new generation of information technology and the integration of network platforms of all shapes and sizes and the combination of the real world synonymous. Smart City? is the result of the transformation and upgrading of the urban development model, building a new modern urban development model that is open and innovative, green and ecological, and civilized and scientific.?

In the process of smart city construction, for enterprises, due to the market is not clear, the implementation still needs process. In the recently held 2012 China (Shanghai) Smart City Summit Forum, Wisdom China (Holdings) Limited Chief Strategy Officer Cao Guohui said: ? Safe City has been promoted for many years, and its main bottleneck is that we over-emphasize the city's biased construction, without emphasizing the operation, management and services of the later equipment.?

Over the past three years, on the development model of the smart city, the major domestic forums and think tanks have carried out a boisterous discussion, only that there is no real model. As can be seen from the current smart city plans released by governments around the world, they prefer to maximize the characteristics, whether from the point of view of regional development, industrial prospects, or obtaining support and attention from higher authorities.

Because the construction of smart cities involves many fields, and the characteristics and level of economic development vary from place to place, there is currently no set of unified management system. Therefore, the Ministry of Housing and Construction on the standard research work related to the smart city, hoping to break the information silos, realize the smart city data **** enjoyment and synergy, the future will also rely on the city card as the basis of interoperability, while taking advantage of the favorable timing of the construction of the smart city, the planning of a new generation of intelligent community construction, service and operation mode.

Yang Xueshan, vice minister of the Ministry of Industry and Information Technology, has said that the smart city is a product of industrialization, urbanization, and information technology convergence in a specific historical moment. Nowadays, the Internet is undergoing radical changes, the speed of emerging technology iteration dramatically accelerated, smart city will lead to new models, new technologies, new applications of another ? fusion? and? convergence?

The result of this convergence cannot be summarized simply as a technological revolution or an industrial revolution, and will ultimately play a role in the entire era of the tone and order of social operation. Technology promotes the progress of the times, the humanities can inhibit the craziness of the times and impulse, which may be the future value of the smart city.
