Smart lamp-posts installed in north China's Tianjin
TIANJIN, July 27 (Xinhua) -- The first batch of 400 smart lamp-posts have been installed in the Sino-Singapore Tianjin Eco-City, local authorities said Friday.
With cameras, censors and display screens attached, the lamp posts are able to collect and analyze data on air quality, traffic flow and traffic violations, according to Zhang Yong at the eco-city's landscape company, which is charge of local infrastructure.
For example, the lamp-posts can monitor the density of key air pollution indicators, such as PM 2.5, PM 10, sulfur dioxide and ozone. When their density surpasses national safety levels, the system will inform environmental authorities to take action.
The lamp posts can also identify illegal parking and plate numbers to provide evidence for law enforcement officers.
Zhang said that more smart lamp posts would be applied in the eco-city in the future, and their functions would be expanded to more areas including monitoring noise and providing wifi.
The Sino-Singapore Tianjin Eco-City is an inter-governmental project between China and Singapore, aiming to tackle global climate change, strengthen environmental protection, conserve resources and build a harmonious society.
