Dr. Li: The space-time information cloud platform of Intelligent city

Smart city is a topic of great concern to the Government and many research institutes in recent years, and the Director of GIS Institute of China Institute of Surveying and Mapping, Dr.

How to Sublimate Digital city to Intelligent city

The concept of Intelligent city is that intelligent city is a more intelligent way through a new generation of technology to change the way people communicate, improve real-time processing of information, induction speed and response speed, increase business flexibility, continuity, promote the harmonious development of society. The wisdom of the city is generally understood to be easy to publicize the concept, the disadvantage is that it is not a precise definition of the general things, because the wisdom is that we each have different concepts, and therefore can not be precisely defined. But no matter what the general concept, but smart cities are not equal to the Internet of things and cloud computing, it according to our understanding, according to our understanding should be just like the human body, people are intelligent we want to do the city of wisdom, it is clear to me to the outside has the perception, has the feeling, has the sense of touch, to an intelligent city, you should have the ability of intelligent perception , including our various public security video, environmental protection of dust sensors, water pollution monitors, and so on, which are the city's intelligent perception, which is what we call the sensor network, the Internet of things.

Second, human intelligence is the transmission of instructions through the human nervous system to the brain, the sense of perception can be transmitted up, this is the interconnection, that is, now ubiquitous network, including the Internet of things, wireless networks, cable TV network, the same as the central nervous system of the same thing, the perception of things transferred to the center, This center may be the spatial location of distributed integration of various information, in which the integration, processing, to form a number of automatic decision-making things, is equivalent to the human brain. When we have the results of these decisions, and then to each department to command each application, it is the equivalent of our limbs, the brain after the results of the promotion of our behavior, someone with acupuncture me, I can put my fist out to hit him. We feel four aspects: intelligent perception, interconnection, the center of the brain's cloud computing, and support for all kinds of intelligent applications, which are equivalent to the human brain and behavioral organs.

Compared with the intelligent city we used to promote, now 333 prefecture-level cities have already done 300 cities and cities have completed the construction of geo-information, to go to the wisdom of the city, and in the past we have in some applications and technologies, what are the significant changes and differences? I think that only by seizing these differences can we slowly sublimate the digital city to a smarter city.

First of all, mobility enhancement, in the past we are the machine-oriented era, we have to make a phone call 30 years ago may have to find a fixed telephone point, from the home to play a point, to pick up a phone, the following people shout So-and-so a few floors down there is a call you answer! And now the phone is almost simultaneous, people-oriented, not machine-centered. Now that we have built a wireless network, so that we can move up the previous data to go to the center, now this center, this machine is based on your walk, so the human life, working methods have undergone a great change.

Second, the interactivity is enhanced, including now that we can find from the phone, drank a glass of beer I do not want to drive, on the phone can immediately query to the recent help me to drive the nearest person in where, his mobile phone number, can send a text link, let him to where, so the interactivity is stronger. In addition, because of our network interconnection, the synergy between people and individuals has been greatly enhanced.

Of course, the intervention is also stronger, we develop is to put my things into your things, your things involved in me, the relevant infiltration and intervention intensified. Of course, with some dynamic, real-time information after the establishment of the entire intelligent decision-making results more accurate and scientific. So, after such an era, these new technologies, compared to the past, have made a great difference to some of the things that we are facing, and this is the technical background and situation that drives our current digital state to wisdom.

Intelligent city construction under the trend of cloud computing

The state of China's intelligent city construction, at present, about 280 cities do a relatively high level, do the equivalent of the virtual center stage. Mapping is no longer the provision of services, we have called the Public service platform, our maps, geographical information to put on the internet so that everyone can click, enjoy my geographical information services, I think this is a service era. Now, I think it really stands a higher altitude than mapping this industry, standing at the height of the government, I put my geographical information, plus my entire hardware, software environment, constitute a virtual center, this geographical information is just a variety of information overlay a carrier, 30 departments and the government signed an agreement, They all can share information, through the way of distributed registration, let the data still in his department, but throughout the city, all over 170 kinds of thematic information and our geo-information virtual construction, distributed storage, constitute a virtual center. And like some departments, there is no data storage, processing capacity, he put his data processing, computing all storage, commissioned and then to the virtual center, in fact, there is a little cloud computing concepts and ideas.

Systems built by all government departments can use such data and services in a virtual way, is the virtualization of the 1+9 way, 1 centers plus 9 nodes of the service, providing geo-information coding data processing services, but also can help small departments to store data, complete the calculation, which I see the feeling done better.

In contrast, cloud computing is really about pooling all of the resources and providing them with scattered points. Like banks, all retail investors are in the bank, concentrating on what I use and then for one of my purposes. Now that this cloud-computing feature is helping to centralize computing in all sectors, but at the same time these focused resources are concentrated through distributed grids rather than the real building of the cloud center, the building of our national Intelligent City is now in such a state.

In the last five years, we have entered the era of geo-information online service, now through the analysis of the new technical features, through the current analysis of our country's intelligent city, through our understanding of the concept of "wisdom" itself, we feel that although only five years of time the geo-information public online platform services, The next step is bound to move us to the space-time information cloud direction, will soon enter this phase, our mapping industry, our geographic information may give them more than the current platform space-time information cloud Such a thing, what is this kind of thing?
