Smart streetlights are promising

Recently, the reporter learned from the (Guilin) ​​City Lighting Management Department that the first phase of the Guilin Intelligent Lighting Digital Integrated Management System (hereinafter referred to as the “management system”) has completed the mapping of more than 10,000 street lights, control base stations and transformers in the city. The department is preparing for acceptance, and plans to code these street lamps with exclusive “names” next year.With the construction of the management system, it will not only provide convenience for the management and maintenance of street lamps, but also the “name” on the lampposts for citizens. Location targeting.

Smart One: The street light is not bright "Before" know this year, the city lighting management office and the surveying and mapping unit carry out the first phase of the intelligent lighting digital integrated management system construction, the coordinates of the urban street lamp 15550, 350 control base stations, 50 special transformers Data collection, including street lamp types, light source types, lamp pole elevations, lamp pole illumination, and other properties are all thoroughly scrutinized. After completing surveying and mapping, information will be entered into the digital lighting integrated management system. This system can achieve full-time, all-around management of lighting management objects.

When the "management system" is completed, the situation will change dramatically. "Once a street lamp is off or the line is disconnected, the lamp posts can be automatically 'alarmed.'" The person in charge says that the system can show which rod is the faulty street light, and where it is faulty. The orientation of the location allows maintenance personnel to go straight to the site. When repairing, it is not like turning all the street lights that control the base station tube on, but instead of repairing it, it will save time and avoid wasting electricity.

In addition, the "automatic alarm" mode of the lamppost can effectively detect and deter the destruction of public lighting facilities.

Smart II: Where do people “ask” the street lights Some time ago, on the network, there was a message that “the street light poles can be located and we must tell the children”. There is a string of numbers on each street light pole. This string of numbers is the street light. The number corresponds to its precise location, "so when you are in a situation where you are unclear when you call the police, it is the easiest way to report nearby street lights."

According to reports, there are indeed street lights in some cities and 110 data connections, and to achieve the function of street lamp positioning. 110 Received the number of street lights provided by the alarm person. Entering the number in the background system can immediately display the location. The positioning is accurate and fast. However, such systems are currently only visible in some major cities such as Shanghai, Shenzhen and Nanjing.

In Guangxi, only Nanning built and put into use more than 20,000 streetlight coded signage cards in 2012.

Guilin is the second city in Guangxi to build a "wisdom lighting" system. The person in charge of the city's lighting management office told reporters that to achieve accurate positioning of each street lamp, the workload is very large. The location of each street lamp and its neighbors The distance between street lamps must be calculated accurately. At the same time, road signs such as the first row of buildings, isolation belts and green belts around the road should be marked.

At present, relevant departments plan to put numbers on these 15,000-odd street lamps, 350 control base stations, and 50 special transformers next year, and these “names” are exclusive to each street lamp.

The responsible person said that after the completion of the intelligent lighting digital integrated management system, the named street lamp can cover more than 90% of the 224 roads (cells) in Xiufeng District, Xiangshan District, Diecai District and Qixing District. The number on the light pole can provide tourists and citizens with simple and fast location services.

“If a tourist gets lost during a tour, or if someone needs a police help when he encounters a situation, he can also provide the number of a street light pole nearby to confirm his position.” This person in charge said that after coordinating with the public security department in the future, he will coordinate. The management plan enables Guilin's street lights to also serve as a "precise positioning of street poles," allowing 'wisdom lighting systems' to serve the community maximally.

What else can be done besides "smart"?

In addition to being smart, the intelligent street lamp is another major feature of energy saving.

The relevant person in charge of the City Lighting Management Office told the reporter that Guilin started exploring the city's "wisdom lighting" in 2001. According to reports, at that time, the use of wireless communication network, the realization of the monitoring center distributed in the city's lighting Distribution Box remote control box running status real-time monitoring, after two upgrades, intelligent control of street lamp coverage reached 99%.

"Using 'Sanyao' (telemetry, remote signaling, remote control) system and the newly added light sensor detection system can select the best time of light switch in real time according to the weather conditions of the day, avoid turning off the light prematurely and turning off the light too late. Energy wastage was achieved and energy savings were achieved.” However, this control model is only applicable to lighting control within the region, and accuracy is still lacking.

After the "management system" is completely constructed, the intelligent adjustment of the city's lighting system will be more flexible, the coverage will be broader, and the effect of energy conservation will be even more pronounced. "The combination of single light control and street light intelligent control system can achieve 'dark lighting, bright light, bright lights, and fewer lights.'"

In early this year, Guilin City completed the remote intelligent control of a single light of 200 lights between the intersection of Qilidian Road and Jinji Road at the East Second Ring Road, and from the Arctic Square to the newly constructed intersection, the Wushi Street intersection to the North Railway Station, From the Shanghai Road overpass to the Bayi Bridge section, all 174- and 348-inch street lights have also been newly installed with a single light control information module and optimized control system. According to changes in the pedestrian and traffic flow of the road, under the premise of guaranteeing the road lighting standards, the cost will be reduced. Street lighting brightness or take a bright one, one-side lighting, etc., to achieve urban lighting energy saving.

The person in charge said that after calculation, the energy saving rate controlled by a single lamp can reach 60%.

In addition to energy saving, the intelligent "management system" can also realize a real sense of duty on duty and greatly reduce the loss of city lighting inspection personnel and vehicles.
