Big data: The engine of "smart city"

"Smart city" is a form of city built on the support of the new generation of information technology, through the application of information and communication technology, improve the management level of the city, improve the quality of life of the people, make the city run and the citizen life more intelligent. The construction core of "intelligent City" has two points: first, the acquisition and transmission of the required information, and the processing and application of the information obtained. If the acquisition and transmission of information created a "digital city", then through the analysis of information processing and application to obtain support and guarantee the city intelligent operation of decision-making information, it is from the "Digital city" to "intelligent City" the key to the qualitative change.

The information processing and application of
"intelligent City" need to have the ability to obtain decision-making data quickly from the mass information. The ubiquitous mobile devices, RFID, wireless sensors and Internet applications in modern cities are producing huge amounts of data every moment. Take video surveillance As an example, a large city currently used for video surveillance camera about 500,000, a camera one hours of data is a few G, daily video capture data in the amount of 3PB or so. "Wisdom" of "intelligent city" mainly originates from the analysis and excavation of the huge amount of information mentioned above. The application of large data technology satisfies the information processing demand of "intelligent city" effectively. If the sensing sensor is the peripheral of the intelligent city, the city broadband network connecting the sensor is the nervous system of the intelligent city, then the big Data application is the brain of the intelligent city, the intelligent engine of the city running.


large data technology can be used in the "intelligent City" operation of the various links and fields, from macro to micro, to urban planning, small to traffic scheduling, are playing a role in improving decision-making capacity.


in the area of urban planning, a city has experienced many years of construction and operation Management, collected and accumulated a lot of natural information such as geography and meteorology, as well as social humanities information such as economy, society, culture, population and so on, it can effectively forecast the future development of the city by the establishment of the analysis model and the analysis and excavation. can provide strong decision support for urban planning. such as rational layout of urban functional areas, scientific planning of municipal support and accurate prediction of infrastructure capacity, so as to strengthen the urban planning and construction of scientific and forward-looking.


In the aspect of safety precaution, through the Internet, hotline and other channels of keyword search and semantic intelligence analysis, can enhance the timeliness and comprehensiveness of public opinion analysis, timely grasp of sentiment, find man-made or natural disasters, terrorist events, thereby improving emergency handling capacity and security capacity. For example, collect and record the public helpline, connect each telephone with geographic information through the telecom operator's user address information, and combine with the social networking site, municipal road reconstruction, road monitoring equipment and other information for in-depth analysis, the city management department can timely to the potential problems of the pre-sentence, To organize or inform the public about safe haven through contingency plan.


in energy conservation and emission reduction, the use of mobile internet ubiquitous and broad coverage of the characteristics of home appliances and intelligent development trends, can be online management of household appliances, or to carry out the analysis of electricity consumption time. We can realize the function of automatic meter reading and so on, and can obtain the energy use situation on line, do the real-time monitoring and control of the related energy, and provide the reasonable basis for the electricity price time-sharing pricing.


in terms of road travel, the intelligent traffic under the large data is the fusion of the mass data of sensors, surveillance video and GPS equipment, and even the weather conditions such as meteorological monitoring equipment, through the real-time excavation of road traffic information, can effectively alleviate traffic congestion, and quickly respond to sudden situation, It provides scientific decision-making basis for the benign operation of urban traffic. For example: combined with driving direction, number of vehicles, traffic congestion and other information, recommend the best way to travel and routes, so as to effectively achieve vehicle routing and traffic congestion dredging, reduce the time of the public pass.


in summary, large data technology for urban intelligent Management provides an effective tool and means, but the real access to effective decision-making information, but also rely on the experience and wisdom of urban management departments and managers, in the vast data of the ocean to explore the application point, the relevant data extraction and correlation, the establishment of a scientific analysis model, Can give full play to the role of large data.
