[Source: "LED Lighting Channel" January issue / Xionghuan ring] The "Twelfth Five-Year Plan" proposes that the state will actively promote the construction of urban lighting information platform, establish a city lighting information supervision system, and collect basic information of urban lighting and The energy consumption situation will improve the informationization level of urban lighting management work.
“National policies are guiding, local governments are making efforts to promote LED lighting in urban areas, and many lighting companies are also involved in this field. The urban streetlight intelligent control system we launched also hopes to promote the rapid development of the entire industry.†Zhejiang Dafangdazhi Control Song Hongwei, chairman of Science and Technology Co., Ltd., recently said in an exclusive interview with the reporter of "Lighting Market".
"Lighting Market": At this stage, what is the development status of the domestic LED city street lighting intelligent control lighting system? When you return home from overseas, how do you know the difference between foreign development in this respect and China?
Song Hongwei: Domestic demand for urban street lighting control systems is extensive, and our products have been maturely applied to provinces and cities across the country. As the application of urban lighting in the development of Internet of Things, street lighting control system, together with the development prospects of LED lighting, is the general trend and promotes together. There have been relevant provincial and municipal planning policies, and new LED lighting supporting construction intelligent control system, in which LED street light single lamp control is based on the original LED lighting to achieve energy saving, further improve the social and economic benefits of management energy saving, dimming and energy saving. Realize the wisdom of lighting.
Foreign countries are currently market-driven in promoting such projects. First, they gradually transition from indoor low-power products to outdoor high-power applications. Single-lamp intelligent control will develop rapidly in the next three years. Fangda Zhikong is relatively speaking in foreign markets. It is the application of this aspect earlier and the occupation rate is higher. The precise grasp of the foreign market is also one of our advantages.
"Lighting Market": What substantial breakthroughs can the urban streetlight intelligent control system bring? What are the key points in promoting this system?
Song Hongwei: The first is to use energy on demand. According to different time and illuminance of each day, set an illumination band, automatically turn on or off any lamp, and adjust the illuminance according to environmental requirements to achieve energy saving. For example, in the middle of the night when the number of people is small, the brightness of the street lamp is reduced to 30%-40%; when the sensor detects that someone is approaching the car, the brightness is raised again; when the parameter value is set, it operates according to the set value. This makes the lighting device very user-friendly. Such a system can be used not only on street lamps, but also in landscapes, buildings, tunnels, bridges, and public places, so the energy saving effect is considerable.
The second is to improve management through control and monitoring. The street lamp intelligent control system can monitor the energy consumption and power consumption of street lamps, as well as the lighting rate of street lamps, detect faults, and real-time alarms. Real-time alarms, fault detection for maintenance, and timely feedback. For example, in our street lighting renovation project in Stuttgart, Germany, after applying the intelligent control lighting system, we can manage and control local street lights and obtain corresponding data in real time in any place where the Internet can access the Internet, and realize energy saving and economic efficiency.
In the past, intelligent control was a street as a control unit and did not control to a single light. Our intelligent control system includes the main station control software, the main station controller of the field execution layer, and the single lamp controller. The advantage of our current application is that it can be equipped with LED intelligent driving power supply/HID electronic ballast on the original system to realize intelligent management and green energy saving of lighting. A street lamp control module in China needs four or five hundred yuan, which is too costly for street lamp renovation. Our goal is to make the control module stable and compact, to be directly installed in the lamp, and to minimize the cost. Improve the price/performance ratio and make the user really affordable. On the one hand, it is conducive to promoting the popularization of products, on the other hand, it is also conducive to the development and upgrading of industrialization.
"Lighting Market": There is also a voice that LED street lights are not very mature in technology. Most of the projects only replace high-pressure sodium lamps with LED lights, and they have not played its advantages. What do you think of this point of view? ?
Song Hongwei: Many cities are now on the LED streetlight project. From the feedback from the streetlight management unit, the batch effect in 2006 and 2007 is not obvious, but the batch that was replaced in 2009 and 2010 has been greatly improved. Gradually began to be recognized by users. This concern before the industry may also be based on whether it can still be stable in certain unexpected situations or bad weather. Three years ago, LEDs may still have problems of heat generation, heat dissipation, and light decay. However, as technology continues to advance, I personally believe that it is now ready for use.
The LED light is a digital light that can be controlled by mounting it. The high-pressure sodium lamp is also controllable, but there will be differences in dimming. It needs to be digitized and then controlled, so that the cost is relatively high. Our idea is to connect the control module well with the LED driver, so this control is a matter of course. Therefore, the key now is still to reduce the price, improve the cost performance, match the control module and the power supply well, and everyone can apply it widely. This is also the goal we will make unremitting efforts.
From the big concept of the Internet of Things, I think that remote monitoring of urban street lights is an actual application area of ​​the Internet of Things. The Internet of Things has always been a "one net" of everything, and it can be monitored anytime and anywhere. From this perspective, LED street lights can already achieve these functions.
"Lighting Market": The connection between the intelligent control module of LED street light and the driving power supply. Can you introduce the specific situation?
Song Hongwei: Our expertise is in intelligent control, so we cooperate with LED power companies, because the LED power supply itself has no communication function and cannot be remotely controlled. After docking with our control module, the current and voltage of each power supply can be It was monitored remotely. In fact, it is only necessary to add a small amount of cost to the power supply to realize the intelligent power supply and obtain various parameters of the street light. At present, we have practical applications in this area, and we are at the forefront in the control industry.
In addition, we will also cooperate with manufacturers of plant lighting to integrate light sources, modules and electronic ballasts into smart lamps. The application of intelligent control systems to plant lighting is a matter of course. It can also meet the needs of users in this field, and monitor the nutrient solution, water, temperature and other data of crops. It is concentrated on one platform, but the control of plant lighting is fine. The requirements will be higher.
"Lighting Market": What breakthroughs will the intelligent control system have in the future? What is the future development plan of Fangda Zhizhi?
Song Hongwei: In terms of the current LED city street lights, in fact, each lamp can be used as a network point, connected by wires or wireless, and then connected to the control center through a centralized controller, and the whole network is laid. In the future, information such as temperature, humidity, photos, and videos in various places can be collected through this network, not just the switch control of street lamps.
This is also in line with the future development of Zhejiang Fangda Zhizhi. The company first cuts in from the urban streetlight control system. Next, we will develop an energy monitoring platform and expand it to air conditioners, water and electricity, and more, not just lighting. When the industry is fully mature and universal, we will also consider how to apply it to smart homes better and more affordablely.
