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
The invention belongs to teaching equipment, relates generally to a kind of automation driving mechanism that can regulate the blackboard up-down according to writer's writing position automatically.
Background technology
Blackboard is an indispensable important tool in the education activities.At present; The high and low position up and down of the blackboard of various versions moves in the classroom all needs the manual push-and-pull of manpower to accomplish, and not only teachers work intensity increases, and uses the teacher of same blackboard to receive the influence of factors such as height, writing style; Make that blackboard can not fully rationally utilize in the process of giving lessons; Wiping repeatedly, Palingraphia has influenced the effect of writing and give lessons of writing on the blackboard.
Summary of the invention
The purpose of the invention is exactly the problem that exists to above-mentioned prior art; Design provides a kind of blackboard up-down Automatic Control driving mechanism; This mechanism can be according to the position of teacher's height and writing on the blackboard, the up-down that writing time is realized blackboard automatically, reach make the teachers' instruction process more continuously, the utilization of blackboard more rationally fully, alleviate the purpose of teachers work intensity.
The basic design of the invention is; Blackboard up-down Automatic Control driving mechanism comprises writing blackboard; The PLC controller is communicated with image acquisition device, A/D modular converter, I/O module respectively; Described A/D modular converter is communicated with a plurality of linear displacement transducers, and the I/O module is connected with the driving assembly that goes up and down, and goes up and down to drive assembly and is connected with writing blackboard.
The invention has realized the full-automatic lifting of blackboard is driven; "smart" products with automatic technology are provided for educational institution; For the teacher builds the comfortable environment of giving lessons, have rational in infrastructure, use reliable, automaticity is high, help the characteristics that alleviate teachers' instruction labour intensity, improve the quality of teaching.
Description of drawings
Accompanying drawing is a blackboard up-down Automatic Control driving mechanism structure sketch map.
Piece number explanation among the figure:
1, PLC controller, 2, image acquisition device, 3, linear displacement transducer, 4, A/D modular converter, 5, I/O module, 6, up-down drive assembly, 7, writing blackboard.
The specific embodiment
Below in conjunction with accompanying drawing the invention embodiment is described in detail.Blackboard up-down Automatic Control driving mechanism comprises writing blackboard 7; PLC controller 1 is communicated with image acquisition device 2, A/D modular converter 4, I/O module 5 respectively; Described A/D modular converter 4 is communicated with a plurality of linear displacement transducers 3; I/O module 5 is connected with the driving assembly 6 that goes up and down, and goes up and down to drive assembly 6 and is connected with writing blackboard 7.
When manipulating; Image acquisition device 2 and PLC controller 1 are used to gather teacher's height parameter; Calculate teacher's suitable writing position through control algolithm, linear displacement transducer 3 is compared with the suitable writing position that control algolithm calculates through gathering the current position signalling that reaches certain writing time through A/D modular converter 4 and PLC controller 1; When difference surpasses normal suitable writing position scope; PLC controller 1 is seen control signal off, moves in order to drive the upper and lower location of writing blackboard 7 realizations with going up and down to drive assembly 6 through I/O module 5, to guarantee that the teacher writes in its suitable writing in the scope at the horizontal level of blackboard.
