Annual electricity bill 200 thousand! Junior high school student invented intelligent lighting system

According to venture Huizhou reported that the university had to know, one night, a lot of empty classrooms will become self-study room for students to study. But after the self-study, many people forget to turn off the lights, empty classrooms lit five or six fluorescent lamps, a waste of electricity. From the Huizhou University's passion for innovation and entrepreneurship team will develop a set of intelligent lighting system, through sensors and systems to achieve intelligent control of the classroom switch, saving manpower and material resources.

Multi sensor intelligent control light

The idea of intelligent lighting systems in classrooms is derived from life. Lin Xingwei, member of the core team of innovation and entrepreneurship, is a student of the Department of computer science, Huizhou University. Lin Xingwei said in the school from time to time to see the classroom after class a person is not, but a few lights open, that the power waste is very serious, they began to develop an intelligent system to control the idea of lighting.

In Lin Xingwei's vision, this intelligent system to be able to sense whether the classroom as well as outside light changes, so as to achieve automatic control based on the scene, and managers can also networked control. Lin Xingwei in the Department of Computer Science in the embedded laboratory to learn, he and several small partners in the laboratory with the help of teachers to prepare for the development.

"We started in 2014, studied more than a year to complete the final sample. "Lin Xingwei showed us the sample in the system, as well as the demo video. The whole system consists of hardware and software of two parts, the hardware mainly includes infrared sensors, light sensors, RFID terminal node, intelligent switch, gateway, router and server software is a team development control system and management system.

The table will be installed in an infrared terminal node, when someone sits down, the infrared is cut off, the system will be sensitive to the classroom. When the person sitting, the infrared connection, the system will turn off the top of the table, save electricity. Photosensitive sensor is responsible for collecting natural light conditions, when the weather is very bright room is very bright, the system will turn off the lights. RFID terminal node for the teacher attendance, the teacher came to class credit card, the system will know that the classroom has a teacher class, need to use electricity.

In this system, various sensors and switches the data can be collected to the gateway team, and then transmitted through the network to the server, login server management, which classroom is clear, can also be used for manual management in the web or mobile phone.

Lin Xingwei and his buddies calculations, a common classroom lighting electricity is about 1100 degrees, and a smart classroom lighting electricity about 500 degrees, only one room a year can save 600 kwh, down more than and 400 dollars in electricity. Taking Huizhou University as an example, the 433 classrooms in the 4 buildings of the university can save electricity by about $200 thousand a year.

Lin Xingwei said: intelligent classroom system can save more than 50% of electricity for each classroom, and installation costs are not high, the service life of more than 5 years.

R & D circuit board are welding

Lin Xingwei joined the embedded lab when he was a freshman. There are both computer and electronic systems in the laboratory. Under the leadership of the teacher to learn all kinds of knowledge about embedded systems.

Embedded system is a kind of special computer system which is completely embedded in the controlled device, designed for a specific application. Deputy director of the Department of computer science, embedded lab instructor Tang Mingxing said, intelligent lighting system is a typical embedded system, the embedded power management system to realize the intelligent control of the power switch.

Lin Xingwei and the team's other small partners are the first batch of students in the laboratory, two years ago, after entering the laboratory from scratch, step by step to learn all kinds of knowledge. Tang teacher introduced, since the project was put forward, Lin Lin and a few of them have been breaking through various difficulties. Some technical bottlenecks they can not break through, I will give them a direction, let them go to the book, check the information, to solve their own. "

"Welding circuit board, adjust the voltage, sometimes for a chip to find a lot of information or can not find a way. Recall more than a year of research and development process, Lin Xingwei said that the entire system involves multiple aspects of hardware and software, lack of knowledge reserves and sometimes make them quite painful". The team of four or five people together to learn, live, two years down, people mature, communication skills greatly enhanced, a team spirit - Tang teachers look at their growth, given their own evaluation.

Classroom intelligent lighting system cost is low, the business model is simple, the effect is significant, then, Lin Xingwei intends to continue to improve the system, do it fine, fine. Then look for opportunities to conduct a pilot at Huizhou University.
