Rotate forward No. 1 lifting driving motor 1034 by controller 402, No. 2 lifting driving motor 1036 reversions, No. 1 rises
Dropping 1034 output shaft of driving motor drives No. 1 rotating forward of gear 1037, No. 2 lifting 1036 output shafts of driving motor to drive No. 2 gears
1038 reversions are made by being mutually twisted for No. 1 101, No. 2 gear 1038 and No. 2 groove band 102 of gear 1037 and No. 1 groove band
Powder storage unit 103 slowly increases, until powder storage unit 103 rises to the top of display portion 1, when synchronous belt 1054
On 1055 partial insertion powder 104 of slide plate in when, 103 stop motion of powder storage unit.At this moment controller 402 controls slide plate
Driving motor 1052, which rotates and reverse, moves left and right slide plate 1055 in powder 104, until powder 104 is in powder storage unit
Stop after being uniformly distributed on 103, completes the effect of uniform powder.
Next, controller 402 is issued using single-chip microcontroller as the signal of the control system of core, and it is sent to Drive of row and column device
In 406, Drive of row and column device 406 will be precisely controlled array electromagnetic unit in electromagnetic unit display screen 30 according to the signal received
302 power on/off；Make No. 1 lifting driving motor 1034 reversion, No. 2 lifting driving electricity followed by the control of controller 402
Machine 1036 rotates forward, and powder storage unit 103 slowly declines, and the electromagnetic unit 302 of energization will be such that powder 104 inhales by magnetic fields
It is attached on white 2 corresponding position of acrylic board, to form the ad content of default；When light than it is darker when, controller 402
Signal, which can be issued, makes light emitting diode 303 power on 404, and the light that light emitting diode 303 issues will illuminate white acrylic board
2, so that ad content be allow to see clearly.
When needing replacing ad content, by controller 402 and Drive of row and column device 406 by electromagnetic unit 302 from lower
Higher slice and power supply 404 disconnect, and the powder 104 adsorbed will be released, and simultaneously No. 1 lifting driving motor 1034 is being just
Turn, output shaft drives No. 1 gear 1037 to rotate forward；No. 2 lifting driving motor 1036 reversions, output shaft drive No. 2 gears 1038 anti-
Turn, so that powder storage unit 103 rises, recycles the powder adsorbed, realize the effect of ad content erasing.Powder storing dress
Setting 103 rates of climb and powder 104, to be layered rate of release from below to up consistent, prevents powder 104 because filling apart from powder storing
Set 103 it is too far caused by powder 104 be scattered in outside powder storage unit 103.
Next, controller 402 will be such that No. 1 reversion of lifting driving motor 1034, No. 2 lifting driving motors 1036 rotate forward,
Powder storage unit 103 drops in powder demagnetization device 106, until powder storage unit 103 on de- bar magnet 1063 with
Contact chip 1062 is in contact, and access will be formed by this moment taking off bar magnet 1063, contact chip 1062, power supply 404, and controller 402 will make
Electric current in the access changes on time according to setting program, to achieve the purpose that powder 104 takes off magnetic, for use next time.
It is above to complete primary complete ad content presentation and clash process.
Powder storage unit 103 is designed with anti-powder 104 in the place that rectangular frame and white acrylic board 2 are in contact and seeps
The rubber of leakage.
It is the direction by constantly changing direct current that powder involved in the utility model, which takes off magnetic principle, while making to pass through work
The current step-down of part demagnetizes to zero, the number of current attenuation should more as far as possible (generally requiring 30 times or more), decline every time
The current amplitude subtracted is answered as small as possible, if the amplitude of decaying is too big, cannot reach demagnetization purpose, direct current reversing decaying demagnetization
It is a kind of very perfect technology, it is not described here in detail.
Electromagnetism display control technology involved in the utility model, principle are to utilize the control display of AT89C51 single-chip microcontroller
Screen makes it have dynamic display of functional, and can be conveyed in control signal and modification display by host computer to single-chip microcontroller
Hold.Host computer can also realize the long-range control to display system, the electricity by the RS232/485 conversion module of standard
