Abstract
The invention relates to an electronic numerical control blackboard which comprises a blackboard body. The electronic numerical control blackboard is characterized in that an LED matrix board and a controller are further included; the LED matrix board is arranged on the rear portion of the blackboard body in a surface-mounted manner; circular truncated cone holes are evenly distributed in the back face of the blackboard body in a matrix manner; through holes are formed between the circular truncated cone holes and the front surface of the blackboard body and filled with semi-transparent materials; the LED matrix board is provided with LED luminescent tubes evenly distributed in a matrix manner; the arrangement positions of the LED luminescent tubes correspond to those of the circular truncated cone holes; and an outgoing cable is arranged on the LED matrix board and electrically connected with the controller. The electronic numerical control blackboard has the beneficial effects that writing and erasing can be carried out on the blackboard the same as a common blackboard, preset figures, lines and display positions can be selected on the controller when geometric figures or lines need to be drawn, the figures or lines are displayed on the blackboard, and the drawing time of teachers is saved.
Description
Technical field
The present invention relates to teaching field, particularly relate to a kind of electronic numerical control blackboard.
Background technology
Although have employed the multimedia facility fast can shown, contain much information in modern teaching in a large number, blackboard is still requisite instrument in daily teaching.But the deficiency of traditional blackboard is, no matter picture and text all need to write picture by hand, relatively lose time, especially for some general format, during conventional geometric figure, such as by blackboard subregion, blackboard presents the four line lattice writing English, blackboard presents some conventional geometric figures etc., if energy fast processing, effect can be better.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of and can show the electronic numerical control blackboard that basic lines or pattern possess again Hand writing function.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of electronic numerical control blackboard, comprise blackboard body, it is characterized in that, also comprise LED matrix plate and controller, described LED matrix plate is mounted on the rear portion of described blackboard body, the back side of described blackboard body is evenly equipped with round platform hole by matrix, through hole is provided with between described round platform hole and the front surface of described blackboard body, semi transparent material is filled with in described through hole, described LED matrix plate is provided with by the uniform LED of matrix, the arrangement position of described LED is corresponding with described round platform hole, described LED matrix plate is provided with outgoing cable, described outgoing cable is electrically connected with described controller.
Described controller comprises LED drive circuit, single-chip microcomputer, display control circuit and Switching Power Supply, and described single-chip microcomputer, display control circuit provide control signal to described LED matrix plate by described LED drive circuit.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described blackboard body is color steel plate face, and described semi transparent material is epoxy resin or printing opacity fluid sealant.
The invention has the beneficial effects as follows, utilize LED display display and control principle common at present, traditional blackboard is combined with LED matrix plate, when not needing blackboard of displaying subregion or figure, equally with normal blackboard to write, wipe, when the figure, lines and the display position that need to select on the controller when showing geometric figure or lines to preset, then can figure or lines be presented on blackboard, save the time that teacher draws.
