As the concept of creating a"smart city"has taken off in recent years,people have begun to wonder what more can the strewn urban streetlights do with their unique strengths than just provide lighting as it always has.

Wisdom city is on the Internet of things,cloud computing,big data,spatial geographic information integration on the basis of a new generation of information technology,such as by perception,analysis,integration of city run the core system of the key information,for urban services,public safety,environmental protection,all kinds of requirements to make intelligent response,realizes the urban management and service of automation and intellectualization.

Some industry experts have said that in the near future,wireless WiFi,charging pile,data monitoring,environmental monitoring,lamp pole screen and other fields can be realized by relying on street lamps and intelligent control platform.Through renovation and upgrading,LED street lamps can also be equipped with intelligent security,micro base station,information release,new energy electric vehicle charging pile and other systems,thus becoming a"benchmark"for the construction of smart cities.With the national requirements of green and low-carbon,traditional lamps with high energy consumption are bound to be replaced by LED lighting products with high efficiency and energy saving.In view of this,a small number of LED intelligent street lamps are expected to become an important breakthrough in the construction of smart cities.So,what new measures and progress have been made in the application of relevant technologies at home and abroad so far?

Chongqing Yubei Smart City is ready to take off

According to media reports,Chongqing is currently taking"smart lighting"and"lamp pole as the carrier of the Internet of Things"as the breakthrough point,to build a smart city Yubei.Smart lighting alone is said to save 20 percent of electricity consumption each year,and the city expects to complete offline promotion of"smart lighting"in 100 neighborhoods by June.

According to the report,the research and development of the"Internet of Things with lampposts as the carrier"is expected to bring great changes to the daily life of citizens.For example,by adding a variety of sensors and a background big data analysis system to the light pole,the intelligent light pole can monitor and collect traffic flow,noise and other data through a variety of sensors,and analyze the congestion trend.

The original intention of the development of science and technology is to provide convenience for people's life.In time,streetlights could be used to control when and how bright they are,depending on the weather and the flow of people,while lampposts can help make choices to avoid stagnant water,congestion and even serve as a gateway to WiFi.By then,local citizens will be able to access the information in real time through a mobile phone APP,so that they can make a reasonable choice.

Foreign intelligent lighting system put into operation

In recent years,the global awareness of energy conservation and environmental protection has begun to deepen the hearts of the people,and a wide variety of renewable resources have gradually attracted people's extensive attention and expectations.A foreign company has designed a set of new power generation system for this purpose,when pedestrians walk from the ground,can generate electricity for use,very energy saving and environmental protection.

The floor tiles are made of special materials.When pedestrians pass by,the system collects energy and converts it into electricity,which is stored in a lithium battery system.Finally,the green electricity collected will be used to power LED streetlights around the road.

The news indicates that this floor tile power generation system has been installed in a number of foreign cities and schools.Among them,European cities such as London have installed this indoor power generation lighting system,and formally put into operation.Late last year,a similar outdoor power lighting system was installed in Washington,D.C.,and the results are reported to be promising.

Philips Lighting promotes smart lighting solutions to help build smart cities

Philips Lighting,which reported revenues of 7.1 billion euros in 2016,is currently working on providing countries with the foundation to strengthen smart city development through new smart lighting solutions.Through intelligent lighting solutions,will be linked lighting and combined with other application services,in view of the city's streets,interior space,sports venues,public landscape and so on four big face,philips has 33 countries around the world,more than 530 regions to construct the intelligent networking lighting ecological system,to provide people more wisdom of lighting experience.

The functions of smart lighting,such as street lamps,which are widely distributed in cities,include helping local management units to keep track of the city situation in real time and effectively improve public security,transportation and energy consumption.Through the integrated monitoring and management of the system,it can also help to grasp the dynamics of the city,so that the responsible units can eliminate crime and traffic problems in the first time.In addition,can borrow its wide distribution advantage to collect a large number of data and analysis,both in the fault can be quickly repaired,more can be transformed into effective information,to help the future of urban planning and management.At the same time can also monitor the use of the situation,so that the lighting equipment is only needed

Provide services on time,effectively saving 75%of energy consumption.

Philips previously promoted the CityTouch omnidirectional street lighting management system,which combines the software application interface with the actual lighting equipment,through the integration of the network device,so that managers can have flexible control ability and change the way of city lighting operation.With automatic detection and repair reporting,easy to operate interface and real-time remote control capability.The CityTouch solution is intelligent,open and safe,and can meet the needs of county and city management units,citizens and street lamp maintenance units.

Hangzhou to build a standard NB-IOT technology based intelligent lighting demonstration area

In the middle of this month,it was reported that Hangzhou Branch of China Mobile Communications Group,together with Huawei and Zhejiang University Network,completed the construction and verification of Binjiang Smart Lighting Demonstration Zone.Demonstration zone in Hangzhou Binjiang District Shilan micro park,the first construction,installation of 20 NB-IOT street lamps.In fact,as early as last November,Hangzhou Mobile,Huawei and Zhejiang University Network Xinyisheng have jointly signed the NB-IoT tripartite cooperation agreement.After nearly two months of preparation,the street lamp business in the demonstration area has undergone complete and strict testing and verification,and all indicators have met the requirements of single lamp control design.According to relevant agencies forecast,Hangzhou's Xihu District,Jianggan District,Xiacheng District,Gongshu District,Shangcheng District,a total of 140,000 intelligent street lamps will be transformed,Yuhang,Fuyang,Xiasha and other surrounding counties and cities have a total of 200,000 street lamps transformation has also entered the journey.

It is understood that the traditional"two-hop"smart lighting solution is widely used,and in Hangzhou Binjiang Smart Lighting Demonstration Zone,the smart lighting solution will be based on NB-IOT technology,through the operator's NB-IOT cellular network to achieve"one-hop"connection management and control of each street lamp.Compared with the traditional"two-hop"intelligent lighting management system,"one-hop"no longer needs the convergence gateway equipment,which greatly shortens the on-line time of business and reduces the workload of operation and maintenance.Network maintenance can be completely entrusted to the operator.Compared with the traditional scheme of using unauthorized frequency access,the operator's NB-IOT network has strong anti-interference ability and brings higher reliability guarantee.

Relevant statistics show that the compound growth rate of global intelligent street lamps will reach 16%,and the total number of domestic street lamps is about 30 million.Compared with traditional sodium lamps,LED street lamps can save more than 60%of energy,and the current share of LED street lamps in the world is only about 12%.In the next five years,with the accelerated growth of LED lights,as well as the need for further secondary intelligent energy saving,the use of advanced light control mode,the realization of perfect zoning,time-sharing,hierarchical management of intelligent lighting,is expected to become the new driving force for the development of lighting energy saving field.
