According to this lecture, as a representative of foreign smart cities, what are the characteristics of Barcelona's urban construction?

Barcelona's smart city is a comprehensive plan, which includes all aspects of the city, from information infrastructure, public services of intelligent society to green and sustainable development of the city. This is an inclusive and open system.

1. Connect Barcelona

Nowadays, Barcelona's underground comprehensive network has covered the whole city, with the Great Wall network of 375,000m and FTTH covering the whole city 100%. At the same time, citizens can simply and conveniently obtain free Wifi public access points covering the whole city through the app, and 72 1 Wi-Fi hotspots allow citizens to obtain network services anytime and anywhere and enjoy the interconnected network world. "home optical fiber" is a pilot project, in which the Poblenou of optical fiber network is installed indoors and multiplied by the bandwidth of the area. "T-City Friedrichshafen" is an urban digital network. Ultra-high-speed optical fiber and mobile network improve data transmission and realize application. Among them, there are more than 300 kilometers of optical fiber and the basic urban management mode of intensive information application technology.

Step 2 perceive Barcelona

Barcelona attaches great importance to the role of the Internet of Things in smart cities. The city covers a large area of wireless sensors and routers. These devices generate a large amount of data every day, and these data streams are further collected and analyzed on the open software platform to provide guidance for the more effective operation of the city. For example, a unique function of the intelligent garbage collection system is that when it is fully loaded, it will actively send a signal, and the staff will arrange the driving frequency and route of the garbage truck according to the signal sent by it, thus improving the garbage disposal efficiency. So is the intelligent irrigation system. By providing real-time data such as humidity, temperature, wind speed, sunshine, air pressure, etc. through ground sensors, gardeners can adjust the plant irrigation progress according to the basic data and irrigate more scientifically.

3. Open Barcelona

In order to make Barcelona more intelligent, the city chose an open platform, aiming at accelerating the future developers such as sensors, networks, maps and software analysis to use the platform data for them. The platform also allows all departments of the municipal government to share information and avoid duplication of work. For example, drivers only need to download a special application program to know the information of empty parking spaces according to the information sent by the data platform, which is convenient for drivers to park safely and conveniently and prevent the waste of time. Similarly, citizens and tourists can search for the nearest bus stop, geographical location and tourist attractions based on visual map data and interactive browsing.

4. Green Barcelona

Barcelona is committed to promoting the environmental development policy of low-carbon life. In order to reduce carbon dioxide emissions, Barcelona has launched a new green city operation plan, covering energy substitution, traffic management and green buildings. As early as 2000, Barcelona was the first city to support the use of solar energy. By 2006, Barcelona has become the city with the highest density of solar panels in Europe. At the same time, Barcelona vigorously promotes the use of electric vehicles, deploying charging stations in the city, and green transportation-related facilities and services such as electric vehicle fleets and car rentals. By 20 12, there are more than 500 hybrid taxis, 294 public electric vehicles, 262 charging stations, 30 electric motorcycles/kloc-0 and about 400 private electric vehicles in the city.

Step 5 serve Barcelona

Barcelona pays attention to improving citizens' welfare and quality of life, and has made remarkable achievements in smart services that promote people's livelihood, such as smart lighting, smart power grid, smart water affairs, zero mobility, smart parking, smart transportation, smart district cooling and heating, and open government affairs. For example, in 20 12, the city of Barcelona made a master plan, which included controlling 50 street-level street lamps, and a total of 1 155 lampposts adopted LED lighting technology. According to the latest research of the University of Pittsburgh, they can provide the best green substitute for those cities with life cycle research and analysis. For energy-saving LED street lamps alone, Barcelona is expected to reduce its municipal energy expenditure by one third.

6. Innovative Barcelona

Barcelona advocates scientific and technological innovation, and has opened up a plot with an area of about two square kilometers in the city's high-tech center, which is dedicated to research and practice. Because the number of textile industry in the communication library of Barcelona municipal government is 22, this experimental area is called 22@, which means the combination of tradition and modernity. A series of intelligent scientific and technological measures have been adopted in this old city reconstruction plan, including: the promotion of free charging facilities for electric vehicles, intelligent induction garbage collection points, intelligent induction facilities parking garages and parking spaces management, residents' public water management and water-saving schemes. It can be seen from these projects that Barcelona pays attention to the application of innovative scientific and technological means in urban life infrastructure, so as to achieve the purpose of energy conservation and environmental protection and improve the quality of life of citizens.
