The secret behind the Beijing Olympic lighting 179,000 street lamps

For the friends who came to the Olympics, Beijing at night will leave a stunning impression: 179,000 street lamps outline the roads of this ancient city, elegant and holy lanterns in front of Tiananmen Square, and the Olympic Center The moving torch lights are fascinating.

The artists who create the beauty are a group of electric workers who are accustomed to dealing with the night. On the eve of the Olympics, our reporter visited the newly-opened Beijing Urban Road Lighting Monitoring Command Center to explore the interesting secrets behind the lights.

Olympic Central District: 5 minutes to arrive to repair street lights

During the Olympic Games, the Olympic Center is the focus of the world's attention. It is undoubtedly a very important task to ensure the normal operation of more than 2,000 street lamps. We have been involved in the work very early, and in addition to daily inspections, the staff are on duty 24 hours a day. The person in charge of the technical maintenance of the street lights here said. Although the Olympic Center covers an area of ​​more than 300 hectares, once the street lights fail, the maintenance personnel can reach any of the street light poles and carry out repairs within 5 minutes.

A staff member in charge of duty said that the most special thing about this work is to cooperate with the security work. There must be a lot of procedures that must be strictly implemented. Even if only a manhole cover is opened for inspection, it must be reported to the competent department and The public security personnel were accompanied by the homework. The document review of the Olympic Center is very strict. During the Olympic Games, if there is a street lamp that needs temporary repair, the staff can quickly enter the construction through the emergency channel.

According to the requirements, the Olympic Center will use energy-efficient electric vehicles with electric and hydrogen fuels. The repair of street lamps may require the use of professional electric engineering vehicles. In order to avoid the construction work affecting the progress of the event and the rest of the personnel, the engineering vehicle is usually strictly limited to 24 hours before the night to perform street lamp maintenance.

Tiananmen Square: 13-ball Hua Lan uses energy-saving technology

In the Tiananmen Square under the night, the brilliant and magnificent Huaguang has already become one of Beijing's iconic symbols. The citizens who pass through here every day may not have found it. The 13-ball Hua Deng, such as the bright moon, has already quietly used the new energy-saving lighting technology. Today's light ball is equipped with an induction lamp, the service life can reach 60,000 hours, and it can be used for 15 years. According to the technician, this 85-watt induction lamp has better color rendering and comfort than the original 450-watt mercury lamp.

Around 14,000 streetlight poles that stood around the Olympic venues and along the main roads of various cities in Beijing, have also quietly changed inadvertently. These have experienced dirt on the surface of the pole that has experienced sun and rain. In order not to affect the city's landscape, the staff specially refreshed these poles to restore the gray tone of the year. In addition, the surface of these poles has been coated with a layer of transparent special paint, which makes it have a new ability to deal with small advertisements. The small advertisements that are posted will soon fall off automatically and no longer leave unsightly scars. According to the plan, after the Olympics, more than 120,000 streetlight poles in Beijing will be refreshed.

Command Center: Street lights can also receive SMS

At 5 o'clock in the afternoon, a rain cloud quietly descended over Beijing, the light on the street suddenly became dim; 8 pieces of 67? 枷 酒 槌 槌 槌 槌 槌 槌 ? ? ? 警 警 警 警 警 警 警 警 警 警 警 警 警 警 警 警 警 警 警 警 警 警 警At the normal level, after receiving the instruction, the staff sends a control command to the street light, and the city road street lights are immediately turned on at the same time to send the light to the passing vehicles. Relying on advanced computer technology and communication networks, Beijing has been able to turn off or delay the street lights ahead of time according to actual needs.

At present, there are 4 sentinels responsible for monitoring the road illumination value for Beijing, which are stationed at the four corners of the Fourth Ring Road. According to technical experts, the professional name of these four sentinels is a light-sensitive probe. It is only the size of a stamp. Even if you walk through the Fourth Ring Road, it is difficult to appreciate it. Although the appearance is not surprising, the responsibility of the photosensitive probe is very important. According to the data they monitor, the staff can control the changes of the outdoor light in order to provide lighting services to passers-by in time.

In order to let the city road lights be turned on at the same time, I can't think of the most common means of communication. According to the technical staff, most of the street lights on the streets of Beijing are equipped with the ability to receive text messages. Unlike common ordinary text messages, the special text message sent to the street light is actually a set of data. For the layman, it may be like a book of heaven, but it contains various instructions from the command center. In addition to commanding the street light switch, it can also Learn about the status of the street lights and the status of the circuit.
