In the army of innovation and entrepreneurship, in addition to having a skilled social person, there is another group is also eager, this is the college teachers and students team.
The recently concluded "Intelligent Lighting System in Classroom" brought by the passion innovation and entrepreneurship team of Huizhou College at the 4th China Innovation and Entrepreneurship Competition (Guangdong Division) and the 3rd "Pearl Angel Cup" Technology Innovation and Entrepreneurship Competition won the final Of the winning prize, becoming Huizhou five winners of the team. According to reports, the use of the system, classroom lighting can save more than five percent.
Hope to solve the problem of lighting electricity waste
On the afternoon of the 16th, Lin Xingwei, a 2013-level student in Computer Science and Technology Department of Huizhou University, and several classmates were in the embedded laboratory to reassemble and assemble the "classroom intelligent lighting system." Tang Star, deputy director of the computer science department as a supervisor reminds them which aspects need to be improved to improve the intelligence of the system.
Why do you think of such a system? Tang star introduction, in fact, this system took more than two years to study success, inspiration is not suddenly emerge, but from the usual learning and life experience. When we pass by the classroom, we often find that there are not many people in the classroom, but all the lights are on. Linxing Wei said that even some students even left the classroom the last one, it is not related to power, waste is very serious. If this is the case in a classroom, how much electricity is wasted throughout the school year? National colleges and even all the interior lighting, how much electricity is wasted every year?
We realized that this is a very good research project, the design of a classroom intelligent lighting system to solve the serious problem of lighting electricity waste. Tang star introduction, Huizhou University Embedded Laboratory was established for many years, each year teachers and students will collect and discuss new research projects, the final screening part out to do research. "Classroom intelligent lighting system" after a number of selection, and ultimately passed, and set up a dedicated team.
According to reports, starting from 2013, one after another new members to join the team, there are members due to internship and graduation and other reasons to leave. Majoring in sophomore and junior major in computer science, there are also some students of Department of Electronics, activists like Lin Xingwei, who joined together from the grand. Currently, there are seven team members.
Teachers and students work together to solve a number of technical problems
After more than two years of hard work, "Classroom Intelligent Lighting System" has finally come into shape. Lin Xingwei introduction, which includes four modules, namely, smart switches, sensor data acquisition, embedded gateways, WEB server. Its basic principle is to install an infrared tube sensor under each desk and chair in the classroom. Once someone comes in and seated, the sensor will automatically detect someone coming in and turn on the nearest light. If you keep coming in, the sensor will automatically control how many lights you need to light up. If someone left for some time (can be set), is a similar principle, the sensor will automatically turn off the corresponding lamp.
When entering the classroom was dark, what should I do? Intelligent switch can solve the problem. It is installed at the entrance and has two or more lights that control different areas. When the student enters the door, it can be lit by touching. After being seated, due to the function of the sensor, the light in the nearby area will continue to light and the light in the far area will go out. In addition, through the embedded gateway and WEB server, you can achieve the remote control of each classroom lighting, the equivalent of more than an artificial check.
"With this system, classroom lighting can save more than 50% of the electricity," said the team members proudly. However, such a system, after more than two years of development, is not always easy.
In the research process, Lin Xingwei and companions sometimes do not know what is a problem, is the software or hardware? Need to be investigated one by one, very headache.
Instructors Tang star and director of laboratory Zeng Shuhong also deeply understand these difficulties. For example, the system can not be installed during the destruction of the original classroom wiring, otherwise it will be very troublesome and costly. Finally, the power switch can only be replaced by an intelligent switch, which automatically collects the lamp status information or remotely controls it. At the same time, but also learn from "a single line to take power" and other technologies to solve the power problem. Just to solve this problem, it took more than 3 months time. In addition, the system requires the use of multiple components, in addition to purchase, there are still some need to own design, whether it is to buy or design, must take into account the compatibility and energy consumption and other issues, students and teachers spent a lot of effort to study .
Businesses come to discuss cooperation
Huizhou College team of teachers and students to study the "classroom intelligent lighting system" project, from last year has been the National Innovation Training Program for college students, the Guangdong Provincial Planning and other aspects of the reward and funding. In November this year, the project won the fourth China Innovation and Entrepreneurship Competition (Guangdong Division) and the third session of the "Pearl River Angel Cup" science and technology innovation and entrepreneurship competition team winners.
A good project appears, businesses windy move. Tang star introduction, a company in Guangdong to find energy-saving door come first to the Department of Computer to find the project leader Lin Xingwei phone, and then the lead teacher to discuss cooperation matters. Don Star said that the other side is very optimistic about this project and is currently discussing some details. Of course, this system is still making further improvements to make it more intelligent.
Public entrepreneurship, innovation. The state and Guangdong Province have promulgated a series of incentive policies in promoting the innovation and entrepreneurship education reform in higher education institutions. Including innovative personnel training mechanism, improve innovation and entrepreneurship education curriculum system, reform teaching methods and assessment methods, and strengthen innovation and entrepreneurship practice. According to reports, Huizhou University will also introduce documents, innovation and entrepreneurship practice can replace some elective courses, and the corresponding credits.
