What are the differences between developing smart cities at home and abroad?

a smart city is a brand-new entity built on the basic framework of digital city and safe city. The real world and the digital world are effectively integrated through the Internet of Things, and various states and changes of people and things in the real world are perceived automatically and in real time. The cloud computing center handles massive and complex calculations and controls, providing various intelligent services for urban management and the public.

from the perspective of national policies, the overall technical framework of China's "863 Plan" smart city project is supported by the 863 Plan "Smart City (Phase I)" project of the Ministry of Science and Technology, and the overall team of the 863 Plan Smart City Project (Phase I) put forward a "six horizontal and two vertical" smart city technical framework. The "Six Horizons" are progressive layer by layer. The lowest layer is the perception layer of the city, then the transport layer, then the processing layer, the support service layer and the application service layer, and the top layer is the smart application layer, which runs through the whole situation. Security system and standards and evaluation.

To truly realize smart cities, big data technology must be introduced, which mainly includes three requirements. Only through the following three aspects can massive data be collected, processed, processed and analyzed, and truly applied to specific sub-sectors:

1. Big data fusion technology

One of the major challenges facing the construction of smart cities in China is that urban systems cannot be effectively integrated due to standard problems, forming information islands. Therefore, in the field of big data fusion technology, on the one hand, it is necessary to strengthen the construction of big data standards, on the other hand, it is necessary to strengthen the research and development of key technologies such as modeling and fusion of massive heterogeneous data, storage and indexing of massive heterogeneous data columns, and provide standards and technical support for the information integration of the underlying data.

second, big data processing technology

in the process of large-scale data flowing in smart city system, it is necessary to preprocess large-scale data for the sake of transmission efficiency, data quality and security. Big data processing technology often needs to be combined with parallel distributed technology based on cloud computing, which is also a technical solution widely adopted by the international industry at present.

iii. big data analysis and mining technology

big data analysis and mining technology provides powerful decision support capabilities for smart city governance. Compared with big data fusion and processing technology, big data analysis and mining technology is more complex, which is a very challenging technical problem faced by international academic and industrial circles.

with the continuous development of big data technology and the increasingly obvious demand of industry users for big data technology, big data industry applications are blooming everywhere. Xiaobian shares some practical cases at home and abroad for reference by exploring the application of Jin Peng information in smart city big data.

1. Smart Cities in China

In March 213, Beijing's "Smart Chaoyang Service Network" was officially launched. Through the processing and analysis of big data technology, the data is extracted from the support library and sent to the service management system, and then communicated with different user groups through service portals, including WeChat, Weibo, mobile applications, service websites and set-top boxes.

2. Smart Cities Abroad

The municipal government of Stockholm, the capital of Sweden, has set up 18 roadside control stations on the road leading to the city center. By using RFID technology, lasers, cameras and advanced free-flow roadside systems, it can automatically identify vehicles entering the city center and automatically collect taxes from registered vehicles entering and leaving the city center between 6:3 and 18:3 from Monday to Friday (except holidays). By collecting the "road congestion tax", the traffic flow is reduced, the traffic congestion is reduced by 25%, the time required for traffic queuing is reduced by 5%, the road traffic exhaust emissions are reduced by 8%-14%, and the greenhouse gas emissions such as carbon dioxide are reduced by 4%.

3. Smart medical care

Jin Peng Information Medical has set the goal of building a regional health data center based on Intel big data solution, and formed a complete big data solution in Zhengzhou regional health data center. After repeated testing and optimization, this regional health big data computing architecture can meet the performance requirements of high concurrent retrieval and real-time data analysis of massive data (more than 1 million records) and meet the "smart" big data demand.

4. Smart Policing

By making full use of cutting-edge technologies such as cloud computing, Internet of Things, big data and video intelligent analysis technology, GIS (Geographic Information System), GPS (Global Positioning System), mobile communication network, mobile policing intelligent system and digital integration, the policing work is modernized, intelligent, streamlined and visualized.

5. Intelligent transportation

Zhengzhou has established an intelligent bus system, so that bus information can be displayed on the map: for example, the nearest bus will arrive at the station in 5 minutes and is full; The next bus will arrive at the station in 1 minutes, and there are empty seats, so you can choose to take it; Go downstairs for 2 minutes, walk to the platform for 1 minute, and have 7 minutes left. There is still time to sit down and have a cup of hot tea.

6. Smart Fire Fighting

Zhengzhou has established an intelligent fire fighting system. The alarm person only needs to dial 119, and the system will immediately locate the current position of the alarm person and call the surveillance camera in the area where the position is located to determine the disaster location and fire situation.

7. Smart city planning

In urban planning, by mining natural information such as urban geography and meteorology and humanistic and social information such as economy, society, culture and population, it can provide strong decision support for urban planning and strengthen the scientific and forward-looking nature of urban management services.
