LED Intelligent Street Lighting Project wins International Award

No one without car lights sleep

“The key to our awards is the patented technology for incoming vehicle inspection and smart dimming,” said Yuan Feng, executive deputy director of the Institute of Applied Software Technology at the Chinese Academy of Sciences in Guangzhou. The theme of Barcelona’s selection is green and low carbon. A very important aspect.

Originally, the project team staff installed a camera at the intersection, or through the use of existing surveillance cameras to capture the person or car screen, the data will be sent to the back-end management software - cloud control center. The cloud control center uses a streetlight control management system software based on incoming vehicle video monitoring. After analysis, it issues a command to the “central controller” to tell the street light that there is a car or someone passes by and the brightness of the light needs to be increased. At the same time, you can also record the number of vehicles.

This method is very suitable for the sparsely populated areas. The camera is like the "eye" of a street light. The cloud control center is like the "head" of a street light. The "central controller" is installed in the existing transformer box of the street light. At present, the connection between them is made through the wires that the street light originally had.

Earlier this year, 18 LED street lights on Yihui Road in Nansha District of Guangzhou City were installed with this intelligent lighting system. When there is no car, the brightness of the light is 30%, there is a car through, the brightness of the light is 100%. Measured energy savings up to 78.7%, so far stable operation. "Of course, this is the ideal situation. If it is in a busy urban street, the energy-saving effect will not be so good."

Broken street lights can also be automatically alarmed

According to estimates, on the basis of LED lights, the transformation of the public lighting system models, with the video to the vehicle detection function, in general, can achieve 44.2% energy-saving rate. Taking Nansha District of Guangzhou as an example, there are approximately 35,000 street lights in the district, which can save electricity costs of RMB 8.5592 million per year and it is estimated that the cost can be recovered from 2.64 to 2.77.

The energy-saving effect that has attracted much attention is not Yuan Feng’s “love”. Through the terminals of computers, mobile phones, etc., the status of each light can be inquired at any time to maintain the information of the equipment. When the road light fails, active and accurate alarms are not required, and workers are not required to inspect the street light. This kind of provincial labor is the best solution he considers.

At present, Dongguan, Guangdong Province and Sichuan, etc., have begun to install smart lighting systems with different functions depending on the needs of different road sections.

At the award of the World Smart City Awards, it was stated that the smart lighting project in Guangzhou is very innovative and green and low-carbon, which is a good practice.
