The smart city revolution has not stopped its footsteps, and the opportunities of the industry have matured. A few days ago, foreign media LUX identified the top four smart cities, which four cities are they?
Barcelona is well known for its extraordinary strength of smart city. The box on the street lamp contains a carefully tuned computer system that measures traffic conditions, road pollution, crowds, and even the number of pieces posted on Instagram on a particular street.
Sensors installed on street lamps and ground are also used to monitor the weather in Barcelona. A few years ago, Barcelona suffered severe drought and almost no water. Therefore, smart sensors can measure rainfall and analyze the level of irrigation on the ground. This information can be used to adjust the sprinkler system in cities to save water.
Barcelona has also developed the Sentilo Sensor Platform as an open source, which means that urban planners around the world can study the case of a smart city in Barcelona and will refer to it.
It shouldn't be surprising that San Francisco is arguably one of the world's leading smart cities, near Silicon Valley. San Francisco has more LED-certified buildings than any other American city, and the Networked Cities Initiative allows residents to find parking spaces.
Recently, San Francisco announced that 18500 low voltage sodium lamp lamps will be replaced by intelligent LED. The new LED will run through a wireless intelligent monitor, allowing the city to remotely monitor the performance of a single lamp and adjust the light intensity as needed. For example, if there is a road traffic accident, the lights may be on the bright side.
When the lights are broken or burned out, the lights also remind the municipal authorities to create a better life for the residents and save money for the city. San Francisco's new streetlights will be powered by 100% clean energy and, together with wireless controls, will become California's most environmentally friendly streetlights.
Copenhagen is one of the world's most sustainable and intelligent cities, with the goal of achieving carbon neutralization by 2025. Nearly half of the street lamps in cities are replaced by LED. Many of these new lamps have become the backbone of an evolving intelligent network.
As the vehicle passes, the LED streetlights turn on and then darken to ensure that they don't stay on when it's not necessary.
Load sensor lamps can also capture data and analysis, and coordinate urban services. For example, lamps can remind municipal authorities to empty empty bins.
Singapore's goal is to become the world's first "smart country". Sensors and cameras are being installed to track almost all data, from traffic to waste carton capacity.
