The relationship between big data, Internet of things and intelligent city

Large data is the intangible means of production of information society, the concept of the community has been constantly deduce a variety of versions, but on the large data, Internet of things, intelligent city of the relationship between the three, many people are not very clear. In this connection, the reporter interviewed the same side of the Internet industry applications, technical director Zhao Ying, she made a detailed interpretation.

The relationship between big data, Internet of things, and smart city is simple: the development of large data originates from the application of IoT technology and is used to support the development of intelligent city. As an extension of Internet application, IoT technology is in the stage of great development. The Internet of Things is the foundation of Intelligent City, but the category of intelligent city is more extensive than that of the internet of things; smart cities are measured by large data, and large numbers promote the development of intelligent cities; the internet of Things is a catalyst for large data generation, and large data is derived from the application of IoT.

China has entered the big data age

Some say big numbers are coming, but only in America, not in China. The same side of the government data management view is that China's understanding of big data is generally less in-depth or different from that of the US, but it cannot be denied that China has entered a big data age. Now many ministries in China are already studying large data and using large data. The United States has raised big data as a national strategy, but China has not yet made it clear, but it has raised the big data to the same level as defence, and the ministries have issued joint incentives. Our government's sensitivity to large data has increased rapidly, and measures are being taken. Therefore, China has entered the era of large data, this emphasis is from the government level from top to bottom, may not yet spread to the common people level, but all levels of government has been highly valued. Hequan Academician also said: "China will produce the world's largest number of data, we should pay attention to the development and management of large data." ”

The key to big data is sharing. The bottleneck of the development of intelligent city in our country lies in the information island effect, the government departments do not want to open and sub-item data, which results in the fragmentation of data and can not produce the depth value of the data. On this issue, some government departments also have a clear understanding, and began to seek solutions, which are driven by their own needs. Some government departments, for example, have been reluctant to share their data, but are now seeking data-exchange partners, as they become aware of the fact that single data cannot be maximized, and that the exchange of data between departments has been a development trend. At the same time, with the development of various aspects and the promotion of policies, many previously undisclosed data has gradually become public, which is a strong support for the development of large data.

The technology of IoT promotes the development of large data

On the significance of the big data, Zhao Ying cited an example to illustrate the advancement of the Internet of things to large data. After 7.21 heavy rains in Beijing last year, the government took a lot of measures, a very important embodiment is that the Beijing Science and Technology Commission soon set up a special fund to the affected Fangshan and Mentougou, the two areas of emergency management capacity of the upgrading and information construction. The same party participated in the Mentougou project to help Mentougou enhance the early warning capability. The same side of Mentougou original emergency platform for the transformation and upgrading. For example, the monitoring of water level, in some key overpass under the installation of water level, water level to a certain extent will occur early warning, relevant departments can take some measures, this is the application of Internet technology.

What is the relationship between IoT technology and big data? When the point of the water meter increases, more data will be collected, which makes it easier to find some regularity and give an early warning, which is something that can be done naturally by means of large data. In the case of small number of points, the amount of data is not large enough to solve only a part of the problem. So, because there is the internet of things, the point of large data cloth more and more, naturally will be to analyze real-time data. Data mining, originally for historical data mining, now for real-time data mining is also a trend, the technology of the Internet of things to promote the development of large data-related technologies.

Large data supports the development of smart cities

Urban operational signs are quantified by data, however, these data scattered in various government departments, the role of the same party is to collect data on the city's operational signs of various departments, to help city managers to carry out data collection, analysis, and ultimately the quantitative form of urban signs, namely, various types of data management for government managers to use.

Every decision made by the government department requires long-term research, and the data from the government departments and the long-term accumulation of urban operation. The rapid development of government informatization has led the government to produce hundreds of TB of data. But the data itself has no meaning, only after a certain system analysis, can play the value of data. Every detail of a smart city produces huge data, and the foundation of a smarter city comes from a deep analysis of large data.

The surface of large data is a series of static data piling, but its essence is to make a series of dynamic process of the law after complex analysis of data. The government departments themselves do not do such a thing, which requires the support of enterprises, the same side to see the big data on the importance of urban operation, the choice of government as a breakthrough, the situation is the development of the requirements, but also the unique data of the same party. It is worth noting that the same side of the large data is not involved in government decision-making, but to provide data support for government decision-making. Show the relationship between the business with the visual form of the data, use the data to express the change and trend of the city, analyze and summarize the problems in the city, and provide assistance for the decision of the government department.

The management of urban operational signs also requires the promotion of large data. When large data reflects the city's operational signs, does not need to understand the city department's main business and the operation flow, purely from the data point of view, through the computer software analysis, the data can arrive some laws, does not relate to the business, does not relate to the result, but can fully reflect the correlation between the data. From a large data point of view, driving the development of urban operational signs, is a can be in front of the decision to dig out the manpower of the pure computer mode of operation, such benefits are the quantification and standardization of operations.

For large data, Internet of things and the development of intelligent cities, China's authoritative experts in information technology-the State Council group leader in Internet of things, Hequan academician of China Academy of Engineering has a very profound expression: from the Internet of things to large data to the intelligent city, is the "scientia" process, through the analysis of decision-making to achieve "unity of knowledge and practice."

Smart City Benefits Everyone

A smart city driven by big data is a matter of life for everyone. The most common example is the weather forecast, the previous weather forecast will only predict the weather, but today's weather forecast will tell the public more information, such as weather index, air Pollution index, clothing index, driving safety index, etc., even for sports, the impact of hair and makeup are explained. This is to enable ordinary people to experience the wisdom of life, the future, education, transportation and other aspects of people's livelihood will become wisdom. In education, we can look at the practice of the United States, every university in the United States will be the rate of promotion, employment, the annual level of graduates, such as the actual display, which is very useful for students to choose the school profession is very favorable data support. Traffic, how to smooth the city traffic, how to find parking spaces, choose which means of transport more convenient security, are the future state of Intelligent city.

When it comes to the future development of smart cities, Zhao Ying says: Smart cities come from intelligent decisions, and intelligent decisions come from human intelligence. When everyone is wise, a city becomes wise.
