Problems solved by technology

At present, the up and down movement of blackboards with various structures in the classroom requires manual push and pull. Not only does the labor intensity of teachers increase, but also teachers who use the same blackboard are affected by factors such as height and writing habits. The blackboard cannot be fully and rationally used, repeatedly wiped and written repeatedly, which affects the writing and teaching effect of blackboard writing

Embodiment Construction

[0009] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Blackboard lifting automatic control drive mechanism includes writing blackboard 7, PLC controller 1 communicates with image acquisition device 2, A / D conversion module 4, I / O module 5 respectively, and described A / D conversion module 4 is connected with a plurality of linear The displacement sensor 3 is connected, the I / O module 5 is connected with the lifting drive assembly 6 , and the lifting drive assembly 6 is connected with the blackboard 7 .

[0010] During operation and use, the image collector 2 and the PLC controller 1 are used to collect the height parameters of the teacher, and calculate the appropriate writing position of the teacher through the control algorithm. A / D conversion module 4 and PLC controller 1 compare with the suitable writing position calculated by the control algorithm. When the difference exceeds the normal suitable writing...

Abstract

The invention discloses a full-automatic lifting control and drive mechanism for a blackboard, and belongs to teaching aids. A programmable logic controller (PLC) is communicated with an image acquisition device, an analog-to-digital (A / D) conversion module and an input / output module respectively; the A / D conversion module is communicated with a plurality of linear displacement sensors; the I / O module is connected with a lifting drive assembly; and the lifting drive assembly is connected with a writing blackboard. The mechanism can implement full-automatic control, drive and regulation for the height of the writing blackboard according to the height of a teacher, the position of writing on the blackboard and the writing time, and has the characteristics of rational structure, reliability in use, high degree of automation, reduction in the labor intensity of the teacher and improvement on the quality of teaching.

Description

technical field [0001] The invention belongs to teaching equipment, and mainly relates to an automatic driving mechanism that can automatically adjust the blackboard up and down according to the writing position of the writer. Background technique [0002] The blackboard is an indispensable and important tool in teaching activities. At present, the up and down movement of blackboards with various structures in the classroom requires manual push and pull. Not only does the labor intensity of teachers increase, but also teachers who use the same blackboard are affected by factors such as height and writing habits. The blackboard cannot be fully and rationally used, repeatedly wiped and written repeatedly, which affects the writing and teaching effect of blackboard writing. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art, and design and provide a blackboard lifting automatic control dr...
