The relationship between big data, the Internet of Things, smart city is simple: the development of big data from the application of Internet of Things technology, and used to support the development of smart city. Internet of things technology as the expansion of the Internet application, is in the stage of great development. The Internet of Things is the foundation of the smart city, but the scope of the smart city is more extensive compared to the Internet of Things; the smart city measurement indicators are reflected by big data, big data to promote the development of the smart city; the Internet of Things is the catalyst for the generation of big data, big data from the Internet of Things applications.
China has entered the era of big data
Some say big data is here, but only in the United States, not China. Tongfang, which specializes in government data management, says China's understanding of big data is generally less in-depth or different from that of the U.S., but there's no denying that China has entered the big data era. Now many ministries in China are already studying big data and utilizing it. The United States will be big data upgraded to a national strategy, China has not been explicitly mentioned, but has been raised to the same height as the national defense, and a number of ministries and commissions have also jointly issued incentives. Our government is rapidly increasing its sensitivity to big data and is taking measures. So, China has stepped into the era of big data, this attention is popularized by the government level from top to bottom, may not have been popularized to the level of ordinary people, but all levels of government has a high degree of attention. Academician Wu Hequan has also said, "China will produce the world's largest amount of data, to pay attention to the development, utilization and management of big data."
The key to big data is sharing. One of the bottlenecks in the development of China's smart city lies in the information silo effect, the reluctance of various government departments to disclose and itemize data among themselves, which results in the fragmentation of data and the inability to generate the in-depth value of data. Regarding this problem, some government departments are also conscious of it and have started to seek solutions, which are driven by their own needs. For example, some government departments were reluctant to share their data, but are now seeking data exchange partners because they are gradually realizing that single data cannot be maximized, and data exchange between departments has become a development trend. At the same time, with the development of various aspects and the promotion of policies, a lot of previously undisclosed data is gradually open, which is a strong support for the development of big data.
Internet of things technology to promote the development of big data
In terms of the significance of the Internet of things to big data, Zhao Ying gave an example to illustrate the Internet of things technology to promote big data. After the 7.21 rainstorm in Beijing last year, the government took a lot of measures to solve the problem, and one of the important manifestations is that the Beijing Municipal Science and Technology Commission soon set up a special fund to enhance the emergency management capacity and informatization construction for the two affected districts of Fangshan and Mentougou. Tongfang participated in the Mentougou project to help Mentougou improve its early warning capability. Tongfang has remodeled and upgraded the original emergency platform of Mentougou. For example, to monitor the water level, a water level meter is installed under some key overpasses, and an early warning will occur when the water level reaches a certain level, so that the relevant departments can take some measures accordingly, which is the application of Internet of Things (IoT) technology.
What is the relationship between IoT technology and big data? When the number of points of the water level meter increases, more data will be collected, so that it is more convenient to find some patterns and issue early warning, which is the use of big data technology means naturally can do things. In the case of a small number of points, the amount of data is not large enough to solve only part of the problem. So it is precisely because of the Internet of Things, big data cloth more and more points, naturally, will go to analyze real-time data. Data mining, originally for the mining of historical data, now for real-time data mining is also a trend, indicating that the technology of the Internet of Things is advancing the development of big data-related technologies.
Big data supports the development of smart cities
City operation characteristics are quantified through data, but these data are scattered in various government departments, Tongfang's responsibility is to collect data about city operation characteristics from various departments, help city managers summarize and analyze the data, and ultimately manage all kinds of data in the quantified form of city characteristics for the use of government managers. government.
Every decision made by government departments requires long-term research, and the research information comes from the long-term accumulation of government departments' operation and city operation. The rapid development of government informatization has caused the government to generate hundreds of terabytes of data. However, the data itself has no meaning, and the value of the data can only be realized after certain systematic analysis. Every detail of a smart city generates huge amounts of data, and at the same time, the basis for the operation of a smart city comes from the in-depth analysis of big data.
The surface of big data is a series of static data piles, but its essence is the dynamic process of arriving at a series of laws after a complex analysis of the data. Government departments themselves do not go to do such a thing, which requires enterprises to support them. Tongfang saw the importance of big data for city operation, and chose the government as a breakthrough, which is the requirement of the development of the situation, and also the unique features of Tongfang's big data. It is worth stating that Tongfang Big Data does not participate in governmental decision-making, but only provides data support for governmental decision-making. It uses the visual form of data to show the relationship between business, uses data to show the changes and trends of urban development, analyzes and summarizes the problems of the city, and provides assistance to the decision-making of government departments.
The management of urban operational characteristics also requires the promotion of big data. Big data in reflecting the city's operating characteristics, do not need to understand the main business and operational processes of the city department, simply from the perspective of data, through the computer software analysis, the data will be able to derive some laws, not related to the business, not related to the results, but can fully reflect the correlation between the data. From the perspective of big data, driving the development of the city's operating characteristics, is a purely computerized mode of operation that can be shaved out of the manpower in the pre-decision section, which has the benefit of quantifying and standardizing the operation.
For big data, the Internet of Things and the development of smart cities, China's authoritative experts in information technology - the State Council Internet of Things leading group leader, academician Wu Hequan of the Chinese Academy of Engineering had a very esoteric expression: from the Internet of Things to the big data and then to the smart city, it is "Geschichtenhilfe "
The smart city is the process of analyzing and making decisions to achieve "unity of knowledge and action".
Smart cities benefit everyone
Smart cities driven by big data are about everyone's life. The most common example is the weather forecast. In the past, the weather forecast would only predict the weather, but nowadays, the weather forecast will tell the public more information, such as the weather index, air pollution index, clothing index, driving safety index, etc., and even whether it is conducive to sports, and the impact on hair style and make-up are all explained. This is a smart life that can be experienced by ordinary people. In the future, education, transportation and other aspects related to people's food, clothing, housing and transportation will become smart. Education, we can look at the U.S. approach, each university in the United States will be the advancement rate, employment rate, the annual salary level of graduates and other factual displays, which is very favorable to the students to choose a school major data support. Transportation, how to smooth urban traffic, how to find parking spaces, choose which mode of transportation is more convenient and safe, etc., are the future state of the smart city.
When it comes to the future development of the smart city, Zhao Ying said: smart city comes from smart decision-making, and smart decision-making comes from human wisdom. When everyone is wise, a city will also become wise. (The above is from China Transmission Network/tech/detail.aspx?id=29123)
