The invention discloses a kind of magnetic display board, comprise by the evenly distributed display panel formed of multiple magnet unit, described magnet unit comprises: closed shell, the magnetic ball be arranged in described closed shell, the N hemisphere of described magnetic ball is different with S hemisphere color or be coated with different surperficial chromatographs, be full of in seal casinghousing and have hyalomucoid, the rear portion of closed shell is provided with solenoid, and described solenoid is electrically connected with computer by USB device controller.The object of this invention is to provide a kind of magnetic display board, only need show once, power-off successor can keep showing strong state, no longer consumes a large amount of chalks, can not produce dust, energy-conserving and environment-protective, and power down also can not disappear, rapidly and efficiently time saving and energy saving, long service life.
Description
Technical field
The present invention relates to display board, especially a kind of magnetic display board.
Background technology
At present, in universities, middle and primary schools, meeting room, scientific research place etc., substantially still use traditional blackboard to carry out writing words, or use projecting apparatus to explain.Use traditional blackboard to there is following defect: to consume a large amount of chalks, produce dust, erasing out handwriting is inconvenient, if need to explain figure, also needs on-the-spot picture, wastes time and energy; Use projecting apparatus also defectiveness: continue to consume a large amount of electric energy, namely power down disappears, and do not see at comparatively bright environment hypograph, explanation person cannot directly write or change on shadow curtain.
Summary of the invention
The object of this invention is to provide a kind of magnetic display board, only need show once, power-off successor can keep showing strong state, no longer consumes a large amount of chalks, can not produce dust, energy-conserving and environment-protective, and power down also can not disappear, rapidly and efficiently time saving and energy saving, long service life.
For achieving the above object, the present invention adopts following technical scheme:
A kind of magnetic display board, comprise by the evenly distributed display panel formed of multiple magnet unit, described magnet unit comprises: closed shell, the magnetic ball be arranged in described closed shell, the N hemisphere of described magnetic ball is different with S hemisphere color or be coated with different surperficial chromatographs, be full of in seal casinghousing and have hyalomucoid, the rear portion of closed shell is provided with solenoid, and described solenoid is electrically connected with computer by USB device controller.
Also comprise the magnetic pen for writing on described display panel, described magnetic pen is the bar magnet with S pole and N pole.
Background light source is provided with in the surrounding of display panel; Described closed shell is cuboid, closed shell corresponding in the middle part of each magnetic ball is provided with reflex reflector lens, the inwall that four limits of described reflex reflector lens are corresponding to closed shell is suitable, and the middle part of reflex reflector lens offers through hole, and the diameter of described through hole is greater than the diameter of magnetic ball.
Described computer is connected with described USB device controller by usb bus interface, USB device controller passes into reset current to corresponding solenoid by expansion I/O port progressive scan mode, thus the word in computer or figure is shown on described display panel.
Described computer is connected with described USB device controller by usb bus interface, USB device controller sends pulse current to each solenoid by expansion I/O port progressive scan mode, according to the size of pulse current, differentiate whether corresponding magnetic ball overturns, thus the figure on display panel or word are fed back in computer.
Compared with prior art the invention has the beneficial effects as follows: owing to adopting technique scheme, described magnet unit comprises: closed shell, be arranged at the magnetic ball in described closed shell, the N hemisphere of described magnetic ball is different with S hemisphere color, or be coated with different surperficial chromatographs, be full of in seal casinghousing and have hyalomucoid, the rear portion of closed shell is provided with solenoid, described solenoid is electrically connected with computer by USB device controller, computer can control the upset of described solenoid, by the figure in computer and/or text importing on display panel, this structure, compared with existing projecting apparatus, only need show once, power-off successor can keep showing strong state, energy-conserving and environment-protective, and power down also can not disappear, figure under comparatively bright environment, word still can be seen clearly.
Further beneficial effect is: after being equipped with magnetic pen, described magnetic display board can do clipboard and use, compared with traditional blackboard, no longer consume a large amount of chalks, can not produce dust, erasing out handwriting is more convenient, if need to explain figure, do not need on-the-spot picture, by computer directly figure, text importing on display panel, rapidly and efficiently time saving and energy saving; Erasing can use magnetic pen, also can be wiped by computer one key; Long service life, does not directly contact between magnetic pen with magnetic ball, and there are not scratching wearing and tearing each other, what uniquely have friction is glass surface, and glass hard (HRC65Yi Shang) is very high, and wear extent is very little.
Further beneficial effect is: described closed shell is cuboid, is provided with reflective mirror in it, this structure, and reflective mirror can reflect the color of magnetic ball, and make the upper end of whole magnet unit all demonstrate the color of magnetic ball, display effect is better.
