| See how Barcelona build smart city |
Barcelona is the second largest city in Spain, with a population of 1 million 800 thousand. Barcelona is a compact city with an increasing population. There are a number of factors that interfere with the normal life, such as traffic congestion, noise pollution, poor drainage systems, inadequate local transportation systems, inefficient waste management, lack of parking spaces, and so on.
In 2012, the Barcelona municipal government in a project that began 30 years ago to find solutions to these problems. The project aims to bridge the two municipal buildings with optical fiber networks. This inspired the idea of building a smart city of Barcelona. The technical infrastructure of the smart city of Barcelona is based on a fiber optic network called Transversal. At present, Barcelona's fiber up to 500 km!
Then "Barcelona, a" heritage city "into a" Barcelona, an intelligent city "such an ambitious goal in the end is how to complete it? First, the Barcelona municipal government will be the smart city of Barcelona project is divided into 22 projects, including 83 individual small projects. These projects cover all aspects of the normal life of Barcelona.
The idea of smart city Barcelona is that the city can be a network of the Internet. In this way, it can be connected to the city in a variety of different single network, such as traffic, pollution signs, technology, etc.. Barcelona city government will these different smart city project framework in the following 3 technical level:
The first layer: the activity of the sensor's sensing environment
The government has installed a sensor platform called "Sentilo". Considering the platform potential, the municipal government has the Sentilo platform as open resources, resources can be obtained in Github. This will enable any person in the world to use this platform to create their own applications.
Sensors are deployed in every corner of the city, according to the requirements of the project. These sensors are used to monitor changes in the environment, for example, the degree of pollution in a particular area.
The second layer: urban operating system
Urban operating system is the key to open the Internet of things related to data analysis and prediction modeling. It brings together data from each of the city's applications and Sentilo, and analyzes the data. For example, using data collected from the Sentilo on the degree of pollution, urban operating systems can create a graphical visualization. It can also predict the pollution levels in the last few days of the week. This mechanism contributes to the pollution control board to take proactive measures.
The third layer: data sharing service layer
The third layer is a service layer, which is used to share data and analysis from the urban operating system layer. These data can be used by the public to improve urban services and operations. For example, the use of data and forecasts obtained from the city operating system layer, application developers can create a mobile application, to remind users of pollution degree and recommend some appropriate measures. Different items and their effects
traffic system
Barcelona urban transportation system (TMB) has been introduced to an innovative orthogonal bus transit network (horizontal, vertical and diagonal) using hybrid buses. The introduction of this system to make the bus faster, more frequent and more frequent trips.
