The street lights on the street are also brighter every day, and will gradually turn brighter with the advent of the night. intelligent. The journalists learned from the command and dispatching center of the Harbin Street Light Management Office that this street light is indeed a smart LED street light that not only automatically senses the night-time adjustment of the brightness, but also saves 50% of the energy of the street lights in the past. What's more, it also has automatic fault alarm and rain protection. Leakage function.
At present, there are more than 20,000 street lights in the Second Ring Road in Harbin, of which more than 17,000 have been connected to the "smart street lamp" information system. The relevant person in charge of the street lamp management office in Harbin said that the smart street lights can adjust the brightness by themselves, not only can visibility meet the demand, but also be energy-saving. Compared to traditional street lights, the use of LED "wisdom" streetlights saves 50% more energy than in the past. Harbin is actively promoting the full coverage of the smart street lighting system and currently covers 60% of the area within the Second Ring Road. The next step will be to promote it to the Third Ring Road and the surrounding area.
According to information, the Harbin smart street light information system is built by computers with different divisions of labor. Store the characteristics of Harbin's inherent geographic information, such as latitude and longitude, daily sunrise and sunset times, on the computer. At the same time, it is necessary to collect street lighting conditions through the light sensor on the street lights to provide a reference for when to need street lighting.
The journalists saw at the information management platform of the city's street light management office that the street lights were not bright, and the information platform would immediately display the alarm information on the screen. The platform command center would issue instructions to nearby street light maintenance personnel at the same time. The location of the street light will be displayed on the map and it will be sent to the maintenance personnel accurately and quickly. The street lights that have not been completed will be displayed with a red mark in the system. Records that have already been processed will also be kept for future backups.
According to technical personnel, in the past, the management of street lamps mainly depended on manual inspections and public feedback. These methods not only lag behind, but also have high management costs and low maintenance efficiency. The information carried by the intelligent street lighting system established through various technology means such as the Internet of Things technology will form a large database for the analysis and analysis of these big data in the future, with more elaborate and intelligent management of street lights and electric energy consumption, which will greatly save manual inspections. Inspection and maintenance costs will boost the construction of the “Smart Harbin”.
