In order to ease the current power shortage situation, the street lamp department in Tianjin researched and developed a new lighting method and used the street lamp monitoring system to achieve energy-saving purposes. The reporter learned from relevant departments that the implementation of such measures will save about 3.5 million kWh of electricity during the year and extend the service life of lighting equipment.
In the past, cities generally adopted the "night light lighting" method. At night, especially in the middle of the night, pedestrians and vehicles were scarce. A large amount of electricity and energy were consumed and there was an "empty load" phenomenon. Under the current situation of power shortage, the street lamp department of Tianjin City has fully developed and utilized a street lamp monitoring system, striving to save energy and energy consumption, and formulating a new type of “midnight light†lighting method.
In the newly built outer ring road, Jin River, Weijin River, Yueya River, and Fuxing River landscape channels, monitoring terminal RTU was installed and the street light control box was reconstructed at the same time to realize the midnight lamp function, saving about 3.5 million kilowatt-hours of electricity. At present, nearly 92% of street lights in the city have been uniformly opened and closed.
The street lamp monitoring system has just been developed in recent years and has a high-tech street lamp control system. It uses wired or wireless transmission methods to use computer systems to remotely, remotely, remotely monitor street lights, such as opening and closing, running status, and fault monitoring, so as to realize remote monitoring and management of street lamps.
According to the personnel of the street lamp department, there are 77 ground-mounted transformers and 77 low-control boxes on the entire outer ring line, and a total of 2,455 bases of 400W dual-fire lamps. The previous annual electricity consumption was about 7.8 million kWh. The implementation of the midnight light energy saving program will now change the original 400W dual-fire light source to 10W30 in the autumn and winter and 11:30 in the spring and summer. The operation will not only affect the road lighting, but also the festival. Electricity, and effectively extend the life of street lighting equipment.
At the same time, the street lights have also undergone similar transformations to some of the landscape river lighting. The river landscape lights that do not involve road lighting are all turned off at the latter part of the night, and the side lights of the river landscape lights that need to provide road lighting are reserved for road side lighting.
