[Allergy] leaders, distinguished experts, ladies and gentlemen, good afternoon! Just now the director of flowers in Shanghai in the construction of Intelligent city, from the perspective of cultural industry to clarify a lot of truth. I am doing computer distributed processing and network research. During the 25 period, we took some projects for pervasive computing and did some research.
[Allergy] during the 35 period of cloud computing and Internet of things research. Let me look at the relationship and difference between intelligent city and pervasive computing, cloud computing, and Internet of things from a technical point of view.
[allergy] I mainly talk about these three parts today, let's first discuss what is a smart city? There is a lot of talk about how to build a smarter city from the reports. Today we're going to talk about this, and we can look at the smart city from a variety of different angles.
[allergic] but, so far there is no unified definition of how the city of wisdom, so the cities, enterprises, various governments are in practice. So we can also put forward our opinion, and then mobilize us to say what kind of smart city we need, that is, what technical barriers we have to break, and what our goal is to build.
[Allergic] The third part we talk about Shanghai Jiaotong University EPCC Embedded and Pervasive Computing center, which is the Centre and laboratory of my leadership, we did some work in the early 25 period. To illustrate what we've done in the experiments of smarter cities.
[Allergy] first we introduce the wisdom of the city before we look at the example, is how to use wisdom to change our lives. We now have a request to say that I want to buy a iphone4, so far to achieve a smart service or intelligent service is what? This means that you can determine where your current position is and offer some advice.
[allergy] such as shopping malls around 7.3 kilometers away from us, iphone4 stores have 3.6 kilometers, there is a computer city, we to Xujiahui beauty Luo see 5.2 kilometers, there is a supermarket how many kilometers. These locations are surrounded by what kind of environment can be bought iphone4 can now be achieved. That is, marking, user evaluation, road navigation, electronic dog and so on, which we have already done.
[Allergic] But what else has not been done? Assume that the road to the mall in the traffic jam, to the operator's place there is no parking, or to the supermarket he does not sell the iphone4 this paragraph, no goods. To the computer city such as you are a VIP can, although 5.2 kilometers is not the nearest, but I will buy here. This is what we smart city to do, that is, from the dynamic Public information, store information, user characteristics preference information and based on intelligent services, we should be integrated. This is the aspect of the intelligent city.
[allergic] so our pervasive computing service only solves its single, static, single service, not providing comprehensive information. So we want to give more humane, more accurate intelligence service information. Let's say that pervasive computing can access information services in any way at any time and place.
[Allergy] The second intelligent city for the whole social Center to aggregate urban resources better service, and we are in the case of buying a mobile phone, that is, to fully tap our user's information and the city's information to get an aggregation, so you can to the surrounding environment, resources, personalized service to users. In other words, the services in the smart city are not the same as those in pervasive computing.
[allergic] Intelligent City is a society-centric access to urban development of a variety of opportunities, and then for each citizen to provide a more comprehensive service to promote the harmonious development of the city. Also need to excavate and integrate the various information and resources of the city, this is the wisdom city. We say that the city of wisdom is not the internet of things, since the Premier Wen Jiabao in Wuxi in 08 after the call to perceive China, foreign countries are now said to be China.
[allergy] Now China is doing very hot, the internet of Things is not smart city? Internet of things we say is the basic communication facility of intelligent City. It is to connect some RF devices, sensors, wireless sensor, and so on with the goods, connect the objects with people, so that people and these objects, people, and objects between the intelligent identification, positioning, tracking and management of a network. The Internet of Things is still a network. So we say that smart cities need to use things to connect with these concepts, and improve the role of urban intellectualization.
[Allergy] then we say that the internet of things is the lifeblood of intelligent cities, infrastructure can not be less, but the internet of things is difficult to achieve intelligent city, that is, can not provide intelligent services.
[Allergy] 3rd, How does cloud computing look? Our Shanghai overview can be seen, our total population of more than 20 million, the total area of more than 60 million square kilometers, roads and total mileage, housing total is one of the country. Provide a variety of information, city information, traffic information. There are users, ID card A brush information came out, medical records, social files and so on.
[allergic] so that a city in Shanghai a year of information total and user total is more than 10PB, what concept? All the libraries in the United States are 7PB, and we have more than the total Library of Congress in a year. So what we need is a digital center cloud computing Center, so in the process of cloud computing, we need to deal with the huge amount of information.
[Allergy] abroad to the wisdom of the city carried out a lot of research, but also carried out a lot of practice, Japan from 2000 to 2015, three parts of the E-japan, U-japan, I-japan. Singapore, as we all know, it is the most easy to realize the wisdom of the city, the whole country can become a smart city, so called Wisdom 2015 plan.
[allergy] a while ago the former deputy prime minister was elected president of the National University of Singapore to our school, Singapore invested a few billion funds with Shanghai Jiao Tong University, Zhejiang universities to work together to do its wisdom 2015 plan. So Singapore is doing a lot.
[Allergy] The United States knows that it is the first to put forward the concept of intelligent city. So it's now being demonstrated in a city. In fact, our country is currently in a three-step and one-step way to develop a smart city strategy. So we do not have e Shanghai, u Shanghai, I Shanghai, we are directly a smart city. Three steps and one step there are many opportunities and challenges, there are many technical problems inside.
[Allergy] We look, foreign enterprises, the earliest IBM proposed, the wisdom of the Earth. IBM's wisdom of the earth means that the strategic need to cover all aspects of social life for intelligent service. After that, it is the whole of the Earth, for example, how the water and electricity to achieve smart grid, as well as life services. So that IBM first proposed.
[Allergy] Siemens recently said that we do Green city, is to transport, building, water resources, intelligent power supply processing, Siemens is a large German company, put forward the road of sustainable development. General Electric put forward a smart grid, which is also doing a very fierce, in fact, a part of the intelligent city, to maintain sustainable social development of resources and energy.
[Allergy] What are these companies proposing? IBM's simple idea is to constantly propose new concepts to buy his servers, and now IBM's servers are the best sellers in the world. Including Siemens, GM is his equipment to sell out, they put forward this concept.
[allergy] so these enterprises have its limitations, from hardware, support systems, hands-on applications are single-handedly, I give you pack, you use my company's products. This inside is the plasticity is poor, cannot be made, difficult to optimize. Most of our banking systems now use IBM servers. Then you want to look for IBM to upgrade, so here do not dare to use domestic, because the bank reliability is stronger, real-time, security this is the bank to ensure that, so the use of IBM's system.
[allergy] and closed system, which is the content of many companies in many fields. For example, IBM server, it is absolutely impossible to say that I offer you the opportunity of the Siemens industry, you to do my project. IBM's solution must be IBM. So this company, although it has proposed this thing, but inevitably has its closeness and limitations.
[Allergy] We in Shanghai recently, if you pay attention to Shanghai newspapers and periodicals, "Wen Wei Po", "Jiefang daily", "Xinmin Evening News" and so on are vigorously promote the construction of intelligent city, while the chief of telecommunications may be more talks. That is, the basic knowledge, now 3G, 4g,10 trillion broadband into every household, we say infrastructure quickly. There are public facilities, we immediately have to do the public health care, social security and so on to carry out information. There are electronic life intelligent bus, intelligent bus we have done a lot.
[Allergy] But the current car is still in the block, if you drive abroad its GPS is real-time, he will tell you how many kilometers ahead of traffic jams, blocking how long, but our current GPS can not do. Now most of the installed so far does not have this function, my car is not installed on this feature, so very troublesome, I do not know where to plug more, if you can not see never know how far ahead. So this is the infrastructure construction.
[Allergy] so we have to realize the wisdom of the city, just high speed to wisdom, that is, infrastructure from high-speed to wisdom. That is to say, we have so many optical fiber, so many base stations, can not be in the field of communications, Internet of things, pervasive computing, can provide some examples of government to us. Government departments for a while is the people's Congress information system, a moment of the CPPCC's information system are made by the Development and Reform Commission to do the solution, can from point to face we connect into one, and each other can be referenced.
[Allergy] also has the development goal, is all walks of life to share, not only our individual user, the government department, the Enterprise even other service department can achieve. If you look at all the major newspapers and magazines are focusing on. I'm not going to focus on that.
[Allergy] Our vision of a smarter city is three foundations, pervasive computing, Internet of things and cloud computing. According to this situation we are now the basis of information technology is relatively thin, to do the development of leapfrog, so we can not according to foreign enterprises, my department engaged in Siemens, the IBM, the power grid to engage in general electrical appliances, No. We must be self-reliant and design our overall plan, as it is also related to national security. There is also the policy of technically promoting the economic development of society as a whole.
[allergy] what kind of intelligent city we need, the present situation of our country's technical development level, our information industry development level is actually very fast. So far it has caught up with the information developed countries, our wireless communications, our supercomputers, our communications infrastructure have been catching up with the information developed countries, but with many things networking services are separated.
[allergy] so some of the original results, pervasive computing, cloud computing results are to be applied. And our population density needs are more complicated, so we have to be open and stereotyped.
[allergy] that is to say, if I want a department, a business want to participate in, can customize your own service, can join us. Like today's iphone, a lot of software is in there to make money. So now it's open to do. There is also the level of development of the city, information, basic information has been very high, but the wisdom of the construction to do.
[allergy] also has four technical requirements, this time relationship may not expand. That is to promote the upgrading of existing industries, the promotion of economic development to nurture new intelligent services industry.
[Allergy] This we say to do three destructive wall, this I explain, now has three big walls. One is the closed social wall, each system is separated from each other. There are pervasive computing and smart city walls, and the third is service-servicing walls. Society has so far done a lot, is the independent project is incompatible, the system is not open. So we have to build an open, all walks of life can participate in.
[Allergy] What is the wall between a smart city and a service? That means our current service is separated from the location of the service that you do, and it's recommended service. We made a lot of recommendations before we were Eleven-Five, and if you bought a book on Amazon or Dangdang, such as the Ming Dynasty, it would recommend it to you. Therefore, the service should be integrated, user information sharing, to have an advantage. So the integration of our services is a great challenge for a smarter city.
[Allergy] There is also a third, is the universal calculation and wisdom of the city wall, we have 25 years to do a lot of pervasive computing things. But it is difficult to easily transplant into the intelligent city, its information aggregation is not enough. So we have to allow third parties to participate, to solve these problems.
[Allergy] What do we do in the early stage? We have done some work on pervasive computing and cloud computing. This design and build Intelligent city platform, is iservice,iservice get information you want to analyze, to converge, on these information analysis. Your hobbies, user trails, history, etc. Then we integrate the services to provide the service terminals of the intelligent city. This is we give a terminal, we can add everything to the inside, IService.
[Allergy] The key problem to be solved is the evaluation of service characteristics, user characteristic analysis, adaptability excuse and service integration. The first evaluation of service characteristics is how you abstract out its features, how to obtain its features, and the relationship to service dependency. Finally, search for this service, I can provide what kind of service. This is the first.
[Allergy] The second is the analysis of user characteristics, user information is the first, real-time what kind of demand, and then the potential demand, bought after iphone4 is not still want to buy 5? To record this one. Historical records, what kind of electronic products do you like. This user profiling is a technical problem and is rather difficult.
[Allergy] The third is the excuse of adaptability, the upward excuse, we have to give all walks of life to provide a unified excuse for services, down I have a lot of infrastructure, such as I can not only WiFi, I want to the wireless network to give.
[allergy] Last service integration, this is very troublesome, there are also between the company and users, so this is the hardest to do. We are now in the process of temptation. In the 25 period of our pervasive computing because there are 863 key projects, we have done in it, one is the universal computing services. I remember that 2005, 2006 years of pervasive computing is not very hot, at this time to put forward a set of theoretical methods, that is how to propose services.
[allergy] That means you just have to take me with you to identify your person's user trajectory, where you go from where you are. We know that this feature is available on the iphone and can be identified. The person who reads the software on your phone will know where you are and, finally, a multilateral user.
[Allergy] cloud computing We do CPU and GPU architecture. This is what we do, one is the campus when the good is a timely communication. Timely communication is where you communicate with you people, you do not need to communicate the person it will automatically block, the need will automatically add in.
[allergic] Do this practice is that we search a picture is very rare, we are in the cloud computing architecture to achieve a high-definition map, such as you hit a leopard, he put about Leopard Tiger's all print out, this in a few seconds can get results.
[Allergy] because of the relationship between time I can not unfold a lot, if you are interested in continuing to contact me, I am in Shanghai Jiaotong University, now in Minhang. We are in the practice of intelligent City we are willing to participate in the technical framework of intelligent City and some system implementation. Thank you.
