City entrance in the era of big data—smart street lights

Smart lighting is more of a concept applied to urban public lighting. It refers to the remote control and management of urban public lighting systems such as street lights through advanced communication technology, and is an important part of building a smart city. Combining green and energy-saving LED lighting with urban smart street lighting will undoubtedly be able to adapt to the needs of low-carbon, environmentally friendly smart cities. The interconnected LED lighting system can intelligently connect people, space and lighting equipment based on the Internet, not just limited to remote control and energy saving.

In addition to being green and environmentally friendly, the biggest selling point of 　　LED smart street lighting is the word 'wisdom'. Just as Chen Huaitong, vice president of the Institute of Light Environment of the Chinese Academy of Sciences, said, the intelligent light control of LED will benefit people's emotions and health. It can provide the most suitable light source in different occasions. Take students who study at night with lights as an example. The lights provided by LED lighting can make students read more at ease and relax, which can protect students’ eyesight and improve learning efficiency. The smart lighting in the urban public lighting system, by installing detection equipment on each street lamp, can not only automatically adjust the brightness of the light according to the traffic flow, but also realize the detection of incoming vehicles and people; at the same time, it can also be on the centralized control platform. Remotely turn on, turn off, and adjust the brightness of each street lamp. It can also realize functions such as fault and anti-theft alarm.

　　 And these are just the first steps in the contribution of smart street lighting to smart cities, and the word 'wisdom' is far more than that. Some professionals pointed out that smart cities in the 21st century are

　　 uses information and communication technology to sense, analyze, and integrate various key information of the core system of urban operation, and intelligently respond to various needs including people's livelihood, environmental protection, public safety, urban services, industrial and commercial activities, etc. response. It can be seen that the key information about the operation of the city is an extremely important part. In order to integrate comprehensive and useful information, it is essential to have the original big data on the operation of the city. And the smart lighting system that can be found in every corner of the city can become a collector of big data in the city.

　　 lighting and remote control are just the most superficial functions of smart street lighting. From a technical perspective, through the detection and induction terminals installed on each street lamp, the information within the monitoring range of this street lamp can be collected. LED smart lighting will provide first-hand big data for city management. For example, on a student's route home from school, the intelligent lighting system along the road can clearly record what he has done at each node. This seemingly useless information is the core of big data in urban management. What big data technology values u200bu200bis not necessarily causality, but various possible correlations. Through the analysis and integration of massive amounts of data, some unobvious correlations can be drawn from the urban operation process, which can better serve the city management.
