Abstract
The utility model discloses a kind of projection writing on the blackboard integral intelligent blackboard, its structure comprises rolling blackboard, computer, projecting apparatus, it is characterized in that: described rolling blackboard is double does projecting apparatus screen, its mechanical driving part is provided with roll encoder, and roll encoder is connected to computer by USB connecting line or wireless mode.The utility model, by the mode of blackboard-projection interlock, makes projection and blackboard unite two into one, and makes teacher be student explain knowledge more intuitively; During use, Rolling blackboard is connected computer, teacher plays courseware by computer playout software, and teacher can write writing on the blackboard in the position needed simultaneously, shows content below if want, only Rolling blackboard need be passed through, project content will synchronous with writing on the blackboard on move, for the writing on the blackboard no longer needed, teacher only need continue to roll, content is made to be rolled into the blackboard back side, namely by blackboard eraser group auto-erasing; For the part not needing writing on the blackboard, teacher can be projected by touch pad fast scroll.
Description
Technical field
The utility model relates to teaching equipment field, is specifically related to a kind of projection writing on the blackboard integral intelligent blackboard.
Background technology
Blackboard is educational aid conventional in current school eduaction, has had the history in a lot of year, and the educational aid that Ye Shi universities, middle and primary schools are the most frequently used now.
Along with the development of computer technology, porjector technology enters rapidly the daily teaching life of school, and starts to popularize.But, due to the feature of two kinds of educational aids and the problem of teacher's use habit, due to blackboard have conveniently, freely and intuitively feature, projecting apparatus can't replace the position of blackboard, therefore in a lot of classroom, is all that blackboard and projecting apparatus are combined.Because the area of projection screen is very large, need to be put in blackboard position, front, classroom, so just cause projection screen and block large area blackboard and make teacher can not effectively use this problem.
Summary of the invention
The technical problems to be solved in the utility model is: block large area blackboard for projection screen and make teacher can not effectively use this problem, by the mode of blackboard-projection interlock, projection and blackboard are united two into one, makes teacher be student explain knowledge more intuitively.
The technical scheme that the utility model adopts is:
A kind of projection writing on the blackboard integral intelligent blackboard, its structure comprises rolling blackboard, computer, projecting apparatus, it is characterized in that: described rolling blackboard is double does projecting apparatus screen, its mechanical driving part is provided with roll encoder, roll encoder is connected to computer by USB connecting line or wireless mode, can realize the synchronous of the rolling of blackboard and the rolling of projector content.
Rolling blackboard rear portion is provided with blackboard eraser group, content unwanted on blackboard can be wiped in the process of rolling.
At rolling blackboard marginal position, Trackpad is installed, is connected to computer by USB connecting line or wireless mode, the effect of roll screen can be issued to by Trackpad in the situation of not Rolling blackboard.
Computer receives by USB line or wireless mode the data that on blackboard, roll encoder or Trackpad send, and carries out rolling operation to PowerPoint or PDF reader etc., projecting apparatus by computer screen content projection to blackboard assigned address.
The structure of described rolling blackboard comprises the main shaft of blackboard upper and lower end, blackboard panel encloses a closed structure around main shaft, can around the upper and lower circulating rolling of main shaft, and front position place, plate face is provided with backing plate, the dynamics in plate face can be increased when writing, being convenient to write.
The tumbler of described roll encoder is connected to main shaft by belt, realizes the synchronous of rolling.
The plate face of described rolling blackboard is the bamboo curtain splint shape plate face be formed by connecting by some strip planes, and the upper and lower circulating rolling in Convenient blackboard plate face, makes plate face be convenient to write, be convenient to wiping, and can ensure that paint is not easily fallen in plate face.
Described plate face is white or grey, is convenient to projecting apparatus display.
The plate face of described rolling blackboard is the soft blank of dumb light of PET material.
Described roll encoder model is spindle encoder ZSF5815 or spindle encoder 5815-1024-5L etc.
The side, plate face of described Rolling blackboard adds the handle or groove that roll for blackboard, facilitates teacher's Rolling blackboard.
The beneficial effects of the utility model are: the utility model, by the mode of blackboard-projection interlock, makes projection and blackboard unite two into one, and make teacher be student explain knowledge more intuitively; During use, Rolling blackboard is connected computer, teacher is by computer playout software (PowerPoint, PDF reader, word document etc.) play courseware, teacher can write writing on the blackboard in the position needed simultaneously, shows content below if want, only Rolling blackboard need be passed through, project content will synchronous with writing on the blackboard on move, for the writing on the blackboard no longer needed, teacher only need continue to roll, content is made to be rolled into the blackboard back side, namely by blackboard eraser group auto-erasing; For the part not needing writing on the blackboard, teacher can be projected by touch pad fast scroll.
