Shelen: Cloud computing is not so much a technology as an idea.

"2012 Intelligent City and shared services capacity-building seminar" hosted by the China http://www.aliyun.com/zixun/aggregation/18995.html "> Geographic Information Industry Association", ESRI China Information Technology Co., Ltd. In 9-10 days in Tengchong, Yunnan. Professor Shelen, deputy dean of Digital China Research Institute of Peking University, expounds the developing trend of intelligent city from the perspective of the development of intelligent city construction demand and technology frontier, and shares his own views on how to find a starting point for intelligent city construction in the current mainstream IT technology development trend, scientifically and efficiently decision-making, Implementation and management.

Professor Shelen, vice president and doctoral tutor, Institute of Digital Chinese Studies, Peking University

"The theme of this forum is intelligent city and shared services capacity building, I think that captures the key, and I want to share with you the theme of cloud computing, things networking and smart city trends, because when it comes to sharing capacity building, cloud computing, and Internet of things clearly constitute an important technical support for our smarter cities. At the beginning of his speech, Professor Shelen focused on cloud computing and the technology of IoT.

Talk about cloud computing, Shelen think these years the word fry very hot, this kind of enthusiasm is very good, but in the implementation of the lack of doing, hype a little too far, so that everyone is not clear what to do, "we are all foggy." Shelen said cloud computing and cloud services are actually a necessity, "our facilities, hardware and software, especially data, now have to share to reflect the value of information, and only through information, our ability to take off." "He also likened the grid to cloud services," for many traditional areas, this service is very early, such as electricity, you do not need to spend money to build power plants, buy generators, hire workers, as long as you pay the line, you only pay attention to the amount of money on the line, and do not need to know that you are using electricity is the Three Gorges, Or the Daya Bay nuclear power station. It's really nothing new. "Shelen that the nature of cloud computing is not so much a technology as a concept, he also suggested that there should be no excessive concept of the cloud hype."

Then Shelen talked about the internet of things, he thinks that the internet of things is nothing magical, he used a cartoon to explain the concept of the Internet of things vividly, saying that the internet of things is actually "all our items are connected by means of a variety of perceptual devices, which means that all of our information collection does not require manual means." "Shelen believes that the Internet of things enables the real world to integrate seamlessly into information networks without relying on people."

Shelen also talked about the relationship between Digital city and Intelligent city, and that the accumulation of digital city construction in the past more than 10 years has laid a very good foundation for the next intelligent city construction. He also mentioned the problems of digital city construction, called the current digital city, whether based on the grid or based on polygons, although in the space to achieve accurate, digital, but in the attribute, basically quasi-static, can not be dynamic response, so many things can not be prevented in advance, can only be disposed of afterwards. "This is a very passive model, and the data we get are often isolated data, rather than a comprehensive grasp of the city, so in the management are dependent on specific things, it is difficult to play a role in the integrated system." ”

Finally, the Shelen appeal should be in full attention to urban planning, operational mechanism research and the relevant standard design, and actively adopt advanced, applicable engineering technology means, with intelligent ideas, methods and ways to build more intelligent city.
