Integrated intelligent teaching equipment

Abstract

The invention discloses integrated intelligent teaching equipment. The integrated intelligent teaching equipment is characterized in that a writing board of the integrated intelligent teaching equipment further comprises a support board and a writing film, the writing film is attached to a side surface of the support board, and the support board is mounted and connected with a second frame; an upper beam and a lower beam of a first frame and first borders of the second frame are concave pipes, and a convex strip is arranged on a surface of each concave pipe; finger touch operation of people can be sensed by a touch control film and can be converted into touch control electric signals, and an LED backlight source lamp is arranged in a liquid crystal display; the integrated intelligent teaching equipment further comprises a signal processing module and a backlight LED driving circuit, touch control operation continuity information in the touch control electric signals from a touch control driving card can be extracted by the signal processing module, and corresponding backlight brightness adjusting signals can be generated by the signal processing module according to matching relations of the touch control operation continuity and the backlight brightness; the backlight LED driving circuit is connected to the LED backlight source lamp, and the light source brightness of the LED backlight source lamp in the liquid crystal display can be adjusted by the backlight LED driving circuit according to the backlight brightness adjusting signals from the signal processing module and direct-current voltages of alternating-current-to-direct-current circuits. The integrated intelligent teaching equipment has the advantages that large-size touch control interaction setting is infused into the traditional blackboard systems, accordingly, the connotation of blackboards can be enriched, and novel requirements of modern teaching on the blackboards can be met.

Description

Technical field [0001] The invention relates to an integrated intelligent teaching equipment, belonging to the field of modern education equipment and touch technology. Background technique [0002] For a long time, teaching courses in the form of chalk and blackboard has occupied a very important position in the field of education. Not only does it have the advantage of low teaching costs, but the teacher's vivid lectures and the graphic icons or explanations on the blackboard can greatly increase the students' attention and improve the efficiency of learning. But as people have a deeper understanding of certain diseases, the disadvantages of traditional chalk teaching have gradually attracted attention. [0003] At present, ordinary traditional blackboards can only be handwritten with chalk and wiped with erasers. The chalk dust generated by the chalk when writing and wiping will affect the health of the body; at the same time, ordinary traditional blackboards cannot be projecte...

Problems solved by technology

[0003] At present, ordinary traditional blackboards can only be handwritten with chalk and wiped with an eraser. The chalk dust produced by chalk during writing and wiping will affect the health of the body; at the same time, ordinary traditional blackboards cannot use a projector to project on the blackboard. Such as PPT, videos, pictures, animations, etc.) need to use a projection screen for playback, which is cumbersome to operate, and the projection screen and projector only play teaching content, and the interaction performance is poor; on the other hand, the existing touch blackboard, when the teacher When you need to face the blackboard to write, because the brightness of the display is very high, and the distance between the teacher and the display is very close, it will damage the teacher’s glasses for a long time, but if the brightness of the display is reduced, students or audiences will not be able to see the black display clearly content
