Description

An Internet teaching equipment based on big data analysis

technical field

The utility model belongs to the technical field of teaching equipment, in particular to an Internet teaching equipment based on big data analysis.

Background technique

Internet teaching refers to the application of multimedia and network technology under the guidance of certain teaching theories and ideas, through the multilateral and multi-directional interaction of teachers, students, and the media, as well as the collection, transmission, processing, and sharing of teaching information from various media, to achieve teaching. A teaching model of the goal, the existing Internet equipment, due to the support of big data, teachers can download the electronic courseware prepared by themselves in the classroom, search and consult teaching materials and question banks, and conduct statistical analysis on students' homework, etc. Enrich teaching knowledge and improve teaching quality. Internet teaching equipment is usually composed of multimedia host, projector and electric screen. The multimedia host is used to control the teacher's operation, the projector projects the teaching content, and the electric screen is the projection imaging of the projector. The electric curtain is controlled by the control panel to rewind and unfold the curtain. Due to the large size of the electric curtain, it will block the blackboard, which is not conducive to teachers' writing on the blackboard. Therefore, the electric curtain usually retracts the curtain, only when it is necessary to use the Internet for teaching When the electric curtain is installed, it will be unfolded. Since the existing electric curtain is in the curtain, there is no detection unit to detect whether the curtain is normally unfolded, so that when the curtain is stuck in the electric curtain, it cannot be stopped in time, causing damage to the electric curtain, and only relying on the counterweight Blocks straighten the curtain, the curtain is still easy to wrinkle when it is rolled up, causing damage to the curtain, and the dust in the same classroom is easily absorbed on the surface of the curtain, and the electric curtain cannot be automatically cleaned.
