[New Year's Chronicle] Chengdu City "Lamp Bearer": Guarding the "Colorful" of the City
[Explanation] In Chengdu at night, colorful lights illuminate the whole city. Behind the brilliance, a group of people stayed at their posts during the Spring Festival to light up the city, guarding the city’s “colorfulness”.
In recent years, the monitoring of urban lighting facilities has entered the era of intelligent big data.
The reporter learned from the intelligent lighting monitoring platform of the Chengdu Urban Lighting Supervision Service Center that the platform can perform 24-hour real-time data monitoring of thousands of street light distribution boxes and landscape distribution boxes in Chengdu. If abnormal data is detected, it will automatically Call the police.
Liao Jun, the person on duty on the platform, told reporters that in addition to the system's own early warning, the platform has three telephones for citizens to report on urban lighting problems at any time, and at the same time, they must promptly follow up on the opinions of citizens pushed by the municipal platform.

This big data platform can monitor the operating data of the lighting facilities. Once the operating data is abnormal and a faulty alarm occurs, the information can be transmitted to the front-line staff as soon as possible. Dispose of on site.
[Explanation] During the Spring Festival, the Jinjiang River was dazzlingly decorated with ambient lighting, which attracted many citizens to check in at night.
Among the crowd, Zhao Yu, a staff member of the Chengdu Urban Lighting Supervision Service Center, and his colleagues are inspecting the lighting facilities on tree trunks, railings, bridges, and roadsides. If they find faulty equipment, they will immediately take photos and upload them to the maintenance staff. .
During the Spring Festival, a lot of holiday atmosphere lighting facilities were added, which increased the difficulty and workload of staff inspections, and sometimes the daily inspection distance was as high as 100 kilometers.
Zhao Yu said that the inspection is to clean up the "dead corners" of the big data platform monitoring, and the "prevalence" of some lighting equipment requires empirical judgment.

For example, the lampshade on the road is displaced, there is a problem with the projection angle, or its light or lamp color has become weak. In this case, our inspectors need to find these problems on the spot and notify them to report so that they can be dealt with later. .
[Explanation] As the city continues to develop, urban lighting has also upgraded from the original "one lamp, one column" single lighting function to a landscape lighting show, which is deeply loved by the public.
In front of several building landscape lighting walls in the center of Chengdu, the reporter saw several tree-height "boxes" projecting animations of the New Year theme on the walls of the building.
Zheng Zhiduo, a maintenance worker born in the 90s, climbed up the long ladder and entered the work box for inspection. The temperature in Chengdu in the middle of the night was less than 10 degrees, but the temperature inside the box was kept at about 35 degrees.
In a sweat, Zheng Zhiduo must check the operation of the centralized controller and server, and also take out the computer to test whether the coding of the program is normal.
Zheng Zhiduo said that it is necessary to learn a lot of software and hardware knowledge to cope with the complex maintenance needs of new landscape lighting systems and facilities.

In fact, the maintenance of traditional street lights has relatively few types of failures, so we will take a relatively short time to repair. But for building landscape lighting, we will actually have a lot of work, and then it will be very difficult because it involves many hardware problems, and Debugging of software programs.
The amount of knowledge required will be more, and then the installation and maintenance environment will be more complicated, so we may spend a lot of time.
