Problems solved by technology

[0002] With the development of science and technology, traditional classrooms have been gradually replaced by multimedia classrooms. For example, the teaching of English and other courses needs to be carried out with the help of multimedia classrooms. The multimedia classrooms are equipped with intelligent educational equipment, which is convenient for teachers to express better. At the same time, students can also learn more Intuitive understanding, and the projector is one of the most widely used equipment, but the current technical considerations are not perfect, and has the following disadvantages: when the teacher is teaching at night, the fluorescent lamps in the classroom are turned off, and only the projector’s light is kept. Illumination, which in turn will encourage phototaxis flying insects to move in front of the projector lens, causing the projected image to be blocked

Abstract

The invention discloses an intelligent educational device based on big data. Its structure includes a fixed installation frame, a projector main body, a projection lens, a control panel, and an insect repellent device. The projector main body has a rectangular structure and is placed horizontally, and the control panel Nested on the right end of the front of the projector main body, the projection lens is connected through the middle of the front of the projector main body, the insect repellent device is nested on the front of the projector main body and is outside the projection lens, and the fixed mounting frame is fixed on the top of the projector main body by bolts. The suction fan, airflow driving device and infrared sensor are combined, and then when the projector is working, it will continuously monitor the front of the lens. In front of the projector lens, avoid flying insects approaching and causing the projection screen to be blocked.

Description

technical field [0001] The present invention relates to the field of teaching aids, in particular, it is an intelligent educational device based on big data.
