At night, the rows of street lights on the side of the road will light up on time. While providing illumination for pedestrians and vehicles, they also dress up the night scenes of the cities. In order to save energy, several students from Hunan Agricultural University played their whimsical ideas and invented smart street lights that not only calculate the speed of pedestrians and vehicles by themselves, but also automatically adjust the brightness to achieve greater energy saving. This work won the second prize of the 3rd National University Student Environmental Ecological Technology Innovation Competition in September and October this year, and the Excellent Team Award of the 4th Hunan Innovation and Entrepreneurship Competition.
Guo Qing, the leader of the team, is a junior in the vehicle engineering major of the School of Engineering of the school. “Sometimes when I come back late with friends, there may be only us on the whole street, but the street lights are all night and night. It’s on.' Guo Qing said that this is a waste of energy, so he wanted to design a smart street light. Under the guidance of the teacher Hu Wenwu of the School of Engineering, Guo Qing and his classmates invented this adaptive energy-saving street light.
On the morning of October 23, the reporter saw this street lamp in the school laboratory. The street lamp was equipped with a chip independently developed by his team. Guo Qing said that unlike ordinary street lights, this street light can sense whether pedestrians or vehicles are approaching through radar and react. 'It will gradually become brighter after sensing an object approaching, and each street light is connected to a network.'
The experiment found that the closer you are to the street light, the brighter it is. When you are 2 meters away from the street light, the corresponding street light will increase to the brightest brightness. 'It can be adjusted at the distance, and objects within 80 yards per hour can be sensed.' When pedestrians , After the vehicle leaves, the street lights will gradually dim, but they will not be completely extinguished, leaving a weaker light.
