Construction of smart city, urban lighting will be how to achieve intelligent?

Two sessions this year, smart city has become the focus of the topic, the wisdom of the city to promote the development of many industries, lighting companies also want to share a cup of soup. However, the city lighting to achieve intelligent also faces many problems: energy saving and environmental protection, the need for higher and faster transmission speed, high construction costs, technical problems to be solved, etc.. In the case of the country pushing smart city, urban lighting should be how to achieve intelligent?

Urban lighting blowout intelligent promote green lighting

In recent years, the rapid advance of China's urbanization process, the urbanization rate increased gradually, according to the National Bureau of statistics data show that in 2014 2005 to 10 years, China's urban population has increased from 562 million to 749 million, the urbanization rate increased from 42.97% to 54.75%. According to forecasts, by 2020 China's urbanization rate will reach 60% or so, in 2030 will further reach about 66%, when the new urban residents will be added by.

At the same time, with the rapid development of urbanization in the background, with the increase of city population and vehicles, more and more large-scale city road widening project, the National Bureau of statistics data show that in 2004, China's year-end road length of 223 thousand km, has reached 336 thousand km by 2013, the average annual growth rate of 4.66%; at the end of the year. A road area of 3 billion 530 million square metres in 2004 rose to 6 billion 442 million square meters in 2013, an average annual growth rate of 6.91%.

The actual length of the road and the continuous increase of the road area, directly led to the annual increase in the number of urban road lighting lamps. According to the "13th Five-Year" city green lighting plan "target, will Chinese growth of 46% to 12 million new LED lights, street lamps and existing transformation of 50%, the total reached 29 billion yuan.

But the huge energy consumption of urban lighting has been a headache, the data show that the annual power consumption of lighting in London up to about 56000000 degrees! In order to meet the needs of energy saving and environmental protection, the state has issued a "Chinese phasing out incandescent roadmap", "ten" city lights "semiconductor lighting applications, city plan" policy, and in 13th Five-Year, the state invested in energy conservation and environmental protection will be "two times" during the period of more than 12th Five-Year. The big city of China put forward the "13th Five-Year" street LED transformation plan, therefore, the next few years, in the background of government policy support, energy saving and environmental protection type city lighting to replace traditional lighting will become a new growth point of city lighting industry.

With the development of intelligent lighting, urban lighting energy saving and environmental protection has embarked on a new path. In 2016, the world's largest ICT Technology Exhibition CeBIT 2016, HUAWEI for the city street lighting, released the first multi-level intelligent lighting control networking solutions, strong intelligent street lighting in the wisdom of the city on the first layout. Coincidentally, ZTE communications also announced the BluePillar smart Street program as an important landing point of its smart city strategy. In addition, CISCO and CREE reached a strategic cooperation on the city's smart lighting, the two sides with their own lighting technology and Ethernet technology, jointly promote the smart lighting market.

HUAWEI's smart street lighting program claims to be able to save about 80% than the original, had to be amazing. Yang Lin Electronic Technology Co., Ltd. LED lighting R & D department application engineer Liu Yonghua said that the city's intelligent lighting can detect the environment, efficient use of resources, energy conservation and environmental protection. He said: "take an example of intelligent street lamp, road lighting system will be able to calculate the time of sunrise and sunset according to local latitude, in different seasons and different months or even one day to dynamically adjust the lamp switch time, thus not only saving will be more humane; secondly, will install infrared sensors, radar or camera to measure the real-time traffic flow data, people in the street, and then automatically reduce the brightness of the streetlight or interval basis, so as to realize energy-saving lights. "

Too slow? 5G era speed

Maximize the use of city intelligent lighting is to achieve resources, but it also puts forward new requirements, need to be able to handle more data in a shorter period of time, the transmission rate, data processing speed and higher requirements. At present, the common WiFi router can only support 20 devices connected at the same time, huge power consumption, long distance signal transmission speed will become unstable, and very limited information, completely unable to load demand for wireless network of intelligent lighting.

But with the country repeatedly confirmed in 2020 to achieve commercial 5G, these issues will be resolved in the era of intelligent lighting 5G. Now all kinds of 5G oriented technology has been rapidly warming, and now 5G has not only stay in the concept, a lot of technical scheme has been gradually fall, NB IoT (narrowband cellular networking) is undoubtedly one of the most popular.

Dongguan KingSun Au Optronics Co research director Deng Guoqiang said, now the development of communication network has been able to support the smart city. He said: now the communication network to support intelligent lighting is not a big problem, 4G, fiber, especially now the development of 5G technology, are able to have enough technology to support. "

In March 17th, Zhejiang China Telecom Hangzhou branch, HUAWEI Technology Co., Ltd and Zhejiang cloud IOT company three party cooperation, the successful completion of the first in Zhejiang Province Based on the standard NB IoT (narrowband networking technology) the smart lighting project, intelligent street lamp will become number of smart city
