Description

Technical Field

[0001] The present invention belongs to the field of smart classroom management and control, and specifically provides a platform for managing and controlling smart classrooms using the Internet of Things. Background Art

[0002] Smart classroom is a new type of classroom that combines Internet of Things technology, cloud computing technology and intelligent technology, aiming to provide a humanized and intelligent interactive space for teaching activities. It improves the relationship between people and the learning environment through the combination of physical space and digital space, local and remote, and promotes personalized learning, open learning and ubiquitous learning. The development of smart classrooms has gone through the process from traditional classrooms, electronic classrooms, multimedia classrooms to multimedia network classrooms, and finally evolved into smart classrooms. The introduction of smart classrooms has not only changed the form of traditional classrooms, but also cut into the entire teaching process through modern means, making the classroom simple, efficient and intelligent, which helps to develop students' independent thinking and learning abilities.

[0003] However, although the current smart classrooms are electronic when in use, there are many electronic devices in the smart classrooms and some of them may not be turned off, resulting in a waste of electricity. At the same time, the light intensity has a greater impact on students' eyes during the learning process. Whether the light intensity is too high or too low, it will increase students' eye fatigue and may cause students to be myopic or myopia worsens. At the same time, the overall environment of the smart classroom cannot be accurately controlled, which will cause the learning environment to have a certain impact on the students' learning status. At the same time, teachers cannot effectively supervise students who do not study seriously during class, and calling the roll when there are many students is also a waste of time.
