The 15th Guangdong Children's Invention Awards Excellent Works Exhibition ended recently. The work of the new tunnel intelligent lighting system of Li Weiqiang Vocational Middle School in Shunde District won the first prize. This intelligent lighting system is considered to be "integrated with innovation and practicality", and its main researcher, Su Yuheng, a 17-year-old sportsman, has changed the people around him with his achievements in invention and innovation. A view of yourself.
The “new tunnel intelligent lighting system†invented by Su Yuheng (left) team can avoid the waste of resources caused by tunnels.
inspiration:
Tunnels are lit up and waste resources
Su Yuheng invented the "new tunnel intelligent lighting system" inspired by his life experience. "There is a tunnel not far from where I live. When I was reviewing the third day of last year, there were frequent power outages in my home for a few days. I heard that the electrician might be related to the lighting system of the tunnel." He said, "I began to pay attention to the lighting problem of the tunnel. At that time, there were not many cars passing by at night. It was a waste of resources when I turned on the lights, so I thought about how to solve this problem."
His approach is similar to the “defective enumeration method†that the project instructor Min Min said. “If you think of everything around you as perfect, there is no room for improvement. Try to find their shortcomings. Then think of ways to improve, in order to find a breakthrough."
After a period of exploration, one day his mind came up with the idea of ​​controlling the light through infrared induction. Su Yuheng completed the first generation of products with the help of his cousin. After entering Li Weiqiang's vocational school, his work caught the attention of Min Min. Min Min said that at the time, the invention was quite creative and there was room for improvement. Later, classmate Fan Junjie also joined the project, mainly responsible for the design of the work. Under the guidance of the teacher, they completed the second generation of intelligent lighting systems.
A few days ago, the reporter saw their latest finished products in the school's innovative production room. The model of the work is a tunnel. There is still a section of road in front of the tunnel. There are infrared sensor receivers on both sides of the tunnel. The whole model has five sets of receivers, and above the tunnel is the light. Su Yuheng put the toy car on the model to simulate the normal vehicle. When the front bumper of the vehicle goes to the first group of infrared sensor receivers, the lights in the first two rows of the tunnel will light up, and when the vehicle continues to advance toward the tunnel, In the latter receiver, the lights corresponding to the receiver are also illuminated one after another; about 10 seconds after the vehicle leaves the tunnel, the lights in the tunnel are all extinguished.
Evaluation:
Low cost and operability
"The innovation of this system is that the infrared illumination is combined with the delay module to realize intelligent lighting, which will be lit when the car passes, avoiding waste of resources," Su Yuheng said.
According to reports, this lighting system contains infrared receivers, microcontrollers, controllers and lights, adding up to less than one hundred yuan. "If the system is truly grounded, there will be lights in the tunnel. We only need to install an infrared sensing system and re-link the circuit. The cost is about a few hundred pieces, and the operability is very strong," Min said.
The 15th Guangdong Children's Invention Awards Excellent Works Exhibition won a total of 24 first prizes. The “New Tunnel Intelligent Lighting System†invented by Su Yuheng team is one of them. The evaluation of the on-site judges is: “Innovation and practicality†Well combined, it is worth promoting."
In fact, in order to make this system more secure in practical applications, Su Yuheng is still thinking about how to improve. "Now the infrared sensing system adopts point sensing. Since the tunnel is in the wild, if there are dogs and cats passing through it, it will trigger the system, which will cause excessive consumption." He hopes to change the surface sensing type to reach a certain area of ​​the object. In order to trigger the lighting, in order to save power as much as possible.
change:
The game allowed him to regain family support
"The technical application of this invention is not very difficult. The key is that students can think of ways to achieve intelligent lighting through infrared sensing systems." Min Min said, "Participating in similar competitions can exercise students' observation ability and let them discover problems and Solving the problem of training and innovation, this innovative thinking will have a profound impact on the future development of students."
Su Yuheng told reporters that he started training hurdles from the fourth grade of elementary school. In the year of the senior high school entrance examination, he had the opportunity to enter the ordinary high school with sports specialties. "But his own performance is not good. It takes a lot of time every day after going to high school. Training sports, the results will not catch up, so I chose to go to work." He said, "The family is not very understanding of this choice. Now, my parents see that I can participate in various innovative invention competitions, and I can get a little achievement, and my attitude has changed a lot."
At present, Su Yu Hengxue's animation game major, he hopes to work in graphic design in the future, "I hope that I can continue to learn and bring something new to this industry."
