Description
Technical field
The present invention relates to teaching equipment field, especially a kind of line-scan digital camera storage type automatic blackboard.
Background technology
In school, blackboard is a kind of modal educational aid, and along with the raising of people's quality of life, we are more and more concerned about the health of oneself, like this shortcoming of our the common normal blackboard visual field that enters people slowly.Normal blackboard in our erase process, conventionally all can stir up a cloud of dust after having write, and not only teacher can suck dust, and the student who is sitting in former rows also can suck dust.
From material: blackboard from the earliest with blacking, spread upon plank, the hard objects surfaces such as cement, this blackboard is blackboard the earliest, the time of its use is not long, mass ratio is poor.To the water mill glass of the nineties, this blackboard material is more reflective, and the student who is sitting in both sides cannot see the word that teacher writes.Present color coated steel sheet, composite panel, this blackboard is somewhat expensive, moreover it need to slot on wall, larger to the injury of wall.
In addition, existing blackboard writes rear not enough, just the word of finishing writing need to be wiped, and this makes some not have enough time to remember that the classmate of writing on the blackboard has missed some important information, very inconvenient.
Summary of the invention
The technical problem to be solved in the present invention is: for a kind of line-scan digital camera storage type automatic blackboard is provided, easy to operate, automaticity is high; can realize automatic erasing, in wiping process, without stirring up a cloud of dust, there will not be reflective; effectively protect student's eyesight, and can reappear writing on the blackboard content.
The technical solution adopted for the present invention to solve the technical problems is: a kind of line-scan digital camera storage type automatic blackboard, comprise workbench, Revolving blackboard, rotary encoder, alternating current generator, rubbing head, push-rod electric machine and digital line array camera, on described workbench, be fixed with two rotating shafts, described Revolving blackboard is set in outside two rotating shafts, described alternating current generator passes through belt drives Revolving blackboard along two rotating shaft transmissions, described rotary encoder is fixed in rotating shaft, described rubbing head is fixed on Revolving blackboard one side, described push-rod electric machine promotes rubbing head and moves left and right so that the plate face of rubbing head and Revolving blackboard fits, described digital line array camera correspondence is fixed on Revolving blackboard one side.
Revolving blackboard two sides can be used, and by rotary encoder, makes Revolving blackboard have fixing position, and rotary encoder counting is that to take half blackboard breadth be Moving Unit, avoids blocking of teacher's health.
In order to make user easy to operate, the present invention has also designed all-in-one, PLC and touch and has got rid of the whole device of control, and alternating current generator, push-rod electric machine, touch-screen, rotary encoder and all-in-one are connected with PLC respectively, and described digital line array camera is connected with all-in-one.
The present invention has also designed two sensors, and described sensor symmetry is fixed on Revolving blackboard two ends, and sensor is connected with PLC.Active transmitting, the acceptance type sensor on both sides can be surveyed the erect-position of writing teacher.
In order to realize appraise the teacher classroom blackboard-writing quality and the content of courses, reproduction writing on the blackboard content, the present invention records with digital line array camera the content that teachers attend class in classroom, is then stored in the hard disk of computer.If there is after class student to need to print.
On described workbench, be fixed with aluminium section bar, described rotating shaft is fixed on section bar by bearing block, is provided with and can regulates the U-shaped groove of Revolving blackboard degree of tightness on described aluminium section bar.Be not only so whole installation weight and alleviate, and after when Revolving blackboard is used one section, can adjust elasticity by the U-shaped groove on aluminium section bar.
For the irremovable shortcoming of normal blackboard, the present invention is arranged on Revolving blackboard on a workbench that has a universal wheel, is convenient to mobile whole blackboard.Not only be applicable to classroom instruction, and can be used in some meetings, report
Revolving blackboard adopts nylon flat rubber belting, and thickness is 3mm, and during use, any angle all there will not be reflective phenomenon, has effectively protected student's eyesight.
Rubbing head adopts water-absorbing sponge, not only makes to wipe to become easily, and does not stir up a cloud of dust, and has improved normal blackboard stirring up a cloud of dust when wiping.
The beneficial effect of line-scan digital camera storage type automatic blackboard of the present invention is:
(1) do not change teacher's use habit, or use common chalk, write more convenient, comfortable;
(2) the chalk mark on blackboard is not to wipe with hand, and adopts auto-erasing device, and dust from flying absolutely not, has guaranteed that academics and students's is healthy;
(3), no matter in any direction watch, blackboard can be not reflective, effectively protected student's eyesight;
(4) can appraise the teacher in time classroom blackboard-writing quality and the content of courses, reappear writing on the blackboard content, facilitated student's recorded information.

Step 2: after sidelights on of Revolving blackboard 2 are expired, press start key, alternating current generator 8 starts to start, and by belt 9 driven rotary blackboard 2 main shafts 7, rotates, when rotary encoder 12 count down to half-turn (now Revolving blackboard 2 front-back exchanges), PLC6 controls alternating current generator 8 and stops operating;
Step 3: now just write the space of a whole page of word in a side of digital line array camera 5, at this moment can control figure line-scan digital camera 5 by all-in-one 3 and touch-screen 4, press the button of taking pictures, touch-screen 4 output control signals are to PLC6, allow all-in-one 3 communicate by letter with PLC6, at this moment all-in-one 3 reads this signal, open digital line array camera 5(on NET Famework platform, the image capture software Halcon programming Control digital line array camera 5 of recycling Germany specialty, storage picture, printing etc.);
Step 4: press while wiping button, PLC6 triggers push-rod electric machine 11 actions, promotes forward rubbing head 10, and rubbing head 10 is fitted with the space of a whole page of Revolving blackboard 2, and now rotating Revolving blackboard 2 is the word on erasable Revolving blackboard 2.
Compared with prior art, line-scan digital camera storage type automatic blackboard tool of the present invention has the following advantages:
(1) do not change teacher's use habit, or use common chalk, write more convenient, comfortable;
(2) the chalk mark on blackboard is not to wipe with hand, and adopts auto-erasing device, and dust from flying absolutely not, has guaranteed that academics and students's is healthy;
(3), no matter in any direction watch, blackboard can be not reflective, effectively protected student's eyesight;
(4) can appraise the teacher in time classroom blackboard-writing quality and the content of courses, reappear writing on the blackboard content, facilitated student's recorded information.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to claim scope.
