With the continuous advancement of science and technology, wisdom has become a general trend. At present, the state is actively supporting the development of “smart cities†in terms of policies. Relevant data show that there are 193 “smart cities†pilots in China. As the best subdivision of participating in the construction of “smart cityâ€, the intelligent street lamp is naturally promising. Smart Street Lights, Internet + Street Lights... These technologies are quietly changing the way people live, bringing convenience and experience to people like never before.
LED street lights are coming out?
Nowadays, the application of LED has penetrated into many fields of urban construction, such as LED street lights and LED display screens. According to some surveys, the global LED lighting market will reach 21.7 billion US dollars in 2015. By 2015, the scale of China's LED street lamp market is about 23 billion yuan. However, with the pursuit of investment and the continuous spread of technology, the LED industry has rapidly evolved from the blue ocean to maturity, and even the Red Sea.

Lighting has always been a major consumer of urban electricity. How to achieve energy conservation and environmental protection under the premise of ensuring lighting demand is a problem that must be solved. At present, more and more cities are using LEDs to replace traditional lamps, and hope to solve this problem. However, with the large-scale expansion of the city, there are more and more lamps, which cannot be solved fundamentally. The intelligent lighting control system is adopted. This problem can be solved and the second energy saving can be realized on the LED luminaire. The LED supports dimming function. The intelligent lighting control system can dim and control the luminaire according to time, weather or other requirements, and can realize single lamp control and multi-lamp control of the luminaire to further save energy. According to the survey data, plus the intelligent control system LED street light can save 10%~20% on the original LED energy-saving technology.
The traditional lighting system is that the person adjusts the light through the switch, and the intelligent system is based on the instruction of the terminal module, and the signal is transmitted to the control center software through the electronic induction, and the voltage and current amplitude of the circuit are adjusted by the controller, thereby realizing the remote Single or multi-light switch, dimming, monitoring, etc.
In other words, street lights with intelligent control systems can carry more functions. Each street lamp with intelligent control system can have an independent IP address. The single lamp that is connected to the network can realize functions such as precise geolocation, remote control, and operation status tracking, and effectively carry out road condition monitoring and road public facility management. LEDs are combined with advanced technology such as big data, Internet of Things, cloud computing, and communication technologies to improve the ability to respond to urban public management, security, and emergencies. This will bring more possibilities for LED future development. .
Therefore, street lamp manufacturers simply can realize the replacement of LED lighting, and may not be able to stand in the fiercely competitive market. Before the intelligent wave is swept up, it is necessary to reposition its position. Based on the premise of LED lighting technology, expand more. Cooperation in cross-border areas.
Really intelligent street lights are so long
As night falls, nearly 800 miles of street lights on the Shenzhen Bay Port road light up the warm light source. At the peak of the traffic flow, the road ahead is illuminated for the traffic. When the road is running in the early hours, the lights begin to darken. Some roads are brighter and brighter, and the lights will be automatically early or extended in heavy rain and fog.

The above scenes are being staged more and more in some cities. Main roads, secondary roads, branch roads, residential areas... Many street lights have been replaced by this intelligent street light system. The energy-saving renovation project here is completed by Shunzhou Science and Technology and its partners. It is reported that this project is only one of many successful street lighting renovation projects in Shunzhou. At present, hundreds of thousands of street lamps have used Shunzhou intelligent street lamps. system.
Smart street lights are not empty shouting slogans. As an important part of the city's public lighting system and smart city, the intelligent street lamp management system not only achieves the goal of energy conservation and energy waste, but also experiences intelligent dimming, creating a better light environment and improving operational efficiency. At the same time, it is necessary to provide people with higher convenience, enhance the safety of citizens, and realize efficient and beautiful scientific solutions in modern cities.
Based on ZigBee, GPRS and other advanced wireless communication technologies, Shunzhou's intelligent lighting control system has introduced intelligent street light controller (single light controller), centralized manager (also known as intelligent gateway) and energy-saving monitoring platform (WEB, APP, PC end) Three major integrated road lighting solutions can make lighting control more energy-efficient and smarter.

(Attachment: ZigBee is a low-speed short-distance transmission wireless network protocol. Its main features are low power consumption, low cost, low speed, support for a large number of nodes, support for multiple network topologies, low complexity, fast, reliable, and secure. )
The three major components perform their duties in an orderly manner. The street light controller acts as the "eye" of the street light. Combined with ZigBee, the street light management personnel can realize intelligent control of all the lamps in the port in the office, including single lamp control, group control, dimming, etc. The voltage, current, power and power consumption of each lamp; the centralized manager integrating ZigBee and GPRS is the "central nerve" of the whole system. In the near-component ZigBee network, the street lamp controller of the entire area is managed. The remote control can be realized by using GPRS, collecting the data of the street lamp controller, reporting it to the central server, and executing the control command of the central server; the energy-saving monitoring platform is the hero who has learned the "thinking" of the street lamp, and is responsible for managing all the street lamp controllers. The relevant operation commands can be issued, and the entire lighting system can be managed through PC, webpage, smart phone, tablet, etc. The system has various strategies built in, and different management modes are realized, and the user can also customize the strategy to make the management more intelligent. ,Humanize.
Street lights will also "think"
“As long as there is the Internet, you can remotely monitor the operation of street lights.†According to the staff of Shunzhou, the most intimate aspect of intelligent lighting systems is that group control and single-lamp dimming can be realized, especially single-lamp control. Quite a lot. Yuan Feng, executive deputy director of the Institute of Software Application Technology of the Chinese Academy of Sciences in Guangzhou, said: "The degree of management of lighting can be more expressive with single-lamp control."
In the case of large traffic, the maximum power consumption of the luminaire meets the lighting demand. In the case of a small amount of traffic, the brightness of the luminaire can be lowered; in the middle of the night, the street lamp can be controlled to be brighter; and the latitude and longitude control is supported, according to the local The latitude and longitude, according to the seasonal changes and the daily sunrise and sunset time, the switch light time can be automatically adjusted. Such intelligent lighting systems are truly on-demand, making them more human, scientific and intelligent.

Shunzhou Technology Intelligent Lighting Monitoring Platform
On the monitoring system platform shown above, the “light map†of the monitored area can be quickly presented. The street lamp management staff can clearly see the name of each road, the distribution of street lamps, and the number of street lamps. The operating status of the lamps, the power consumption, the total power of the street lamp system, the natural illuminance, the sunrise and sunset times, and Natural information such as weather conditions.
Compared with the traditional "one-size-fit" lighting of traditional street lamps, this new intelligent street lamp can optimize the lighting. It is estimated that this system can save 20%-40% of power consumption, and other operating costs can be reduced by 30%. Left and right, such as management and inspection costs. In addition, because the switching time is reasonably reduced, not only the operating cost is reduced, but also the life of the lamp is extended.
In addition, each lamp has a fault alarm function, combined with GIS map information, accurate positioning can timely understand the location of faulty lamps, convenient maintenance personnel to repair in time, improve lighting rate and reduce safety hazards.
Intelligentization brings wireless imagination to the LED lighting industry. In the future, the urban cloud big data interconnection platform based on “smart street lights†can also realize “intelligence†of urban management, transportation, sanitation, advertising and car networking. Construct a three-dimensional information and security network for smart cities. The launch of intelligent lighting systems will strongly promote the construction of “smart cities†and let the public share the fruits of “wisdomâ€.
In addition to some well-known foreign lighting companies, there are already domestic manufacturers to create intelligent street lamps, but there are not many products that can be stable and reliable, and the price is acceptable. I hope users pay more attention when purchasing products. With the expansion of market demand, the maturity of technology and the development of intelligent street lamp standards, it is believed that more and more high-quality intelligent LED products will emerge, and the coverage of smart street lamps in China will be greatly improved in the future. According to industry estimates, it will be ushered in its outbreak in the next few years.
