Full coverage of 112 roads in Beijing city sub-center with "smart street lights"

The 112 roads in the sub-center are covered by "smart LED street lights", which can automatically adjust the brightness and pre-alarm repairs, remotely control the LED lights, can automatically dim according to the weather, can automatically pre-alarm repairs, and can save 40% of electricity compared with ordinary street lights. Beijing All street lighting lights within 155 square kilometers of the city's sub-center are being equipped with "smart brains". The reporter learned from the Tongzhou District Urban Management Committee that the intelligent transformation of street lamps involves 112 roads, with a total of 6,201 street luminaries, and the renovation is expected to be completed before the end of the year. "Smart street lights" can save 40% of electricity, and it is expected to save millions of kilowatt-hours of electricity for the sub-center each year.

After the renovation of Qunfang Middle Second Street is completed

As night fell, the street LED lights on the second street in Qunfangzhong were lit up, and the bright but not dazzling lights illuminated the road clearly. "There were street lights on this road in the past, but the previous street fixtures were yellow, and there was always a faint feeling when shining on the road." Ms. Yao, who lives near Qunfang Middle Second Street, told reporters that last month, the road LED lights in front of her are "new" and "seems to be brighter than before."

The street lamp replacement is not limited to the second street of Qunfangzhong. The reporter learned from the Tongzhou District Urban Management Committee that in late May this year, 112 roads in the sub center started the intelligent transformation of street lights, involving 6,201 street lights, covering all roads within 155 square kilometers of the sub center.

"Shangxin" street lights are far more than just brighter. In the past, the cables of old street lights were usually buried directly in the ground or erected in mid-air with overhead wires. However, the cables are buried in the ground for a long time, and they are in disrepair for a long time and are prone to aging and short-circuit. The maintenance is also very inconvenient. The old cables must be dug out by "opening the belly" on the road surface.

"This renovation will re-lay pipelines underground, one lamp and one well, and all street lamp cables are buried in the underground pipeline." Wang Shiwei, a staff member of the Landscape Section of the Urban Management Committee of Tongzhou District, told reporters that each street lamp has its own exclusive In the inspection wells, once there are problems such as cable breaks, the maintenance personnel can quickly inspect and repair as long as the inspection wells are opened, avoiding repeated excavation. In the sub-center, 28 roads including Yunjing East Road, Jiukeshu Middle Road and Rixin Road in Liyuan Town will be retrofitted with buried pipes, involving a total of 2,325 street lights.

During the renovation process, all 6,201 street bulbs in the sub-center will be equipped with "smart brains"-single-lamp controllers. Each street LED lamp can communicate point-to-point with the "urban brain" of the Tongzhou District Urban Management Command Center through a single-lamp controller. "After installing a single-lamp controller, when the street lamp is switched on and off, and how to adjust the brightness, you can directly issue instructions through the computer system for remote control and remote adjustment." Wang Shiwei introduced. In the past, the brightness of street lamp could not be adjusted. From the beginning of the night until the lights were turned off the next morning, they were all at the same brightness. With the "intelligent brain" of the single-lamp controller, the street lamp can automatically adjust the brightness according to the weather and time. Under normal circumstances, the street lights can be automatically adjusted to 100% brightness from the lights on at night to 12 midnight. After 12 o'clock in the middle of the night, when pedestrians and vehicles on the road decrease, the brightness of the LED street lights will automatically decrease, and the brightness will be adjusted to 60% to 80% , Until the lights are turned off.

Not only that, the 6201 street lamps will be replaced with more energy-efficient new energy LED lamps from the high-pressure sodium lamps that used to be "power-consuming" in the past. The reporter learned from the Tongzhou District Urban Management Committee that with the intelligent control system and power-saving lamps, all street LED lighting lamps within the 155 square kilometers of the sub-center can save 40% of electricity, which can save millions of kilowatt-hours each year.

What should we do if the street lamp fails? In the past, if you wanted to find street lamp failure, you could only rely on the "stupid way." One is to rely on the inspectors to keep on patrolling the car, try their luck on the streets, and quickly report for repairs when they find a street lamp that is not on. The other method is to rely on the masses to report. After the single-lamp controller is installed, once the street lamp fails, it will automatically warn and report for repair. Maintenance personnel only need to follow the "help signal" issued by the street lamp to find the faulty street lamp and then repair it.

"The renovation started in late May this year, and 85% of the total project has been completed. It is expected that all the street lights within the 155 square kilometers of the sub center will be fully intelligentized by the end of the year." Wang Shiwei said, after the renovation is completed, the smart road lights It will be incorporated into the sub-center intelligent management system to realize remote control, remote adjustment, and remote measurement.
