Description

Ad information display device with pattern direct input function

The utility model discloses a kind of is the direct information display device of importing of a kind of pattern, character that core constitutes with the one chip microcomputer.

At present, a kind of large-scale advertisement display is arranged on the market, it is with the top-end computer of being furnished with Chinese character base, adopts keyboard to import kanji code one by one and carries out the advertisement editor, and output shows then.This kind mode can not be imported pattern, equipment cost height, and need special computer operation technology and can use, so this technology be difficult for popularizing, and also very insufficient for the application of computer system, cause very big waste.

The purpose of this utility model is that to people provide a kind of cheapness easy, wieldy information display is to adapt to the needs that occasion information such as large-scale advertisement, car and boat bulletin, commodity report show.

The utility model reads in the computer controller of device and shows the dot matrix driver and be used for reading in the information carrier that the thin type trnaslucent materials of mark constitutes synchronously by row and formed by being printed on by comprising dot matrix.

This device pattern, character directly the method for input be Rack and promptly have with the thin type translucency information carrier of the latent lattice of dot matrix equal number (as tracing paper etc.) on, draw out pattern that desire will show, character etc. with colored solutions such as prepared Chinese ink, latent lattice both sides are printed on or draw and are useful on the mark (as black patch) that reads in by row, this information carrier is passed from paper seam (56) lining of wearing that the dot matrix on the computer controller reads in device (53), and this width of cloth pattern or character have just been deposited in computer.Dot matrix reads in device, and light receiving element such as phototriode (55) are formed one to one by row's luminescent device such as coloured light emitting diode (54) and a row and its.When information carrier when passing therebetween, have the luminous point of pattern or character light to be blocked, quick triode ends, the information of reading in is " 1 "; Light passes the transparent place of pattern-free character, the phototriode conducting, and the information of reading in is " 0 ".

Computer controller is a core with singlechip chip (10), forms a kind of system that adapts to this matching requirements by expansion external RAM (14)～(21) with EPROM(12).The input circuit that dot matrix reads in device is made up of triple gate (2)～(7), and " 1 " on the phototriode, " 0 " state are transferred to the data bus gradation by these triple gates and read in.Eight input ends of triple gate (1) link to each other with toggle switch (42) on the panel, and what read in by it is that two 4 binary-coded decimal is given.When computer controller was operated in the pattern input state, this was given as and deposits figure number in, specifies the first address in certain memory cell district; When controller was operated in the pattern displaying state, this is given just to become with the second was dot matrix pattern displaying time length given of unit.The selection of pattern input or two kinds of duties of pattern displaying is by panel-mounted switch k ₂(43) decide, this two states is with interrupt mode work.Display mode switch k also is housed on the panel ₃(44), its effect is when computer controller is in the pattern displaying duty, and display mode is selected, and the definite of display mode can have the display mode that resembles the curtain pull type from left to right at leisure by deciding behind the program inquiring; The card dynamic formula display mode of rotating by the width of cloth as lantern slide (the method can formation activity display frame) is also arranged; Also has the display mode of rolling by the width of cloth from bottom to up.

When computer controller is in pattern input service mode, it at first inquires about the state that dot matrix reads in two synchronous luminous points of device head and the tail, if these two luminous points read in simultaneously and are " 1 ", illustrate that the 1st row pattern-information delivers to, read in all luminous point information of the 1st row successively this moment under Single-chip Controlling, can read in such as 32 row points inputs minutes for 4 times, read in 8 at every turn, and they are stored in the specified address location district of toggle switch code this moment successively go.Remove to inquire about the synchronous luminous point of the 2nd row after the 1st row run through again,, just the information of the 2nd row is read in if be " 1 " simultaneously ... circulation is always gone down, and up to running through all column informations, just need read 128 row such as 128 row point.Such width of cloth pattern or some characters just are converted into one group " 1 ", " 0 " code is stored in the computer and has gone in a data designated memory cell district.Just can comply with last method with the 2nd, 3 after stirring dial switch ... width of cloth pattern, character deposit computer in.

When computer controller is in the pattern displaying mode,, at first show the 1st width of cloth pattern that deposits in such as being in the moving display mode of card when (showing) by the width of cloth.Under the control of single-chip microcomputer, get 4 byte information of the 1st row earlier successively from the data-storing district of depositing the 1st width of cloth pattern, layout becomes the serial port RXD output of series form from single-chip microcomputer, delivers to the information input terminal of line control module (45) after driving; Under the control of single-chip microcomputer, export the input end CK of a string displacement CP signal (32 or 48 group) simultaneously to shift register (25)～(27) of line control module from its TXD mouth, under the control of this displacement CP, just be loaded into from the serial information of RAM district taking-up among the shift register of line control module; The single-chip microcomputer commentaries on classics removes to control alignment control module (46) then, promptly earlier send the input end of " 1 " signal to alignment serial shift register (37) from delivery outlet P1.2, send out a shift pulse from mouth P1.1 again, make the 1st alignment be output as " 1 ", open the 1st all clamp diodes that list, single-chip microcomputer is sent out the control end of triple gate (29)～(31) of a parallel output signal to the line control module again afterwards, deliver on all lines the 1st column information of packing into just now is parallel, finished and once sealed in and go out conversion, this moment, crossing high-power memory cell one-way SCR or the state that just whether triggered by line by the thyristor gating circuit that triode is formed on the 1st alignment and all lines were determined, line is cancelled for the corresponding controllable silicon clamper of " 1 ", the controllable silicon conducting, bulb is lighted; Line is not just lighted for the bulb of " 0 ".Like this, " 1 " in the 1st column information of taking-up, " 0 " code just convert the bright, dark of the 1st row bulb to.According to same method, take out the 2nd column information, different is only to send out a shift pulse for the control of alignment, make " 1 " signal move to the 2nd row by the 1st row, and other each row still remain " 0 " at this moment, the 2nd all clamp diodes that list have so just been opened, make the 2nd whole one-way SCRs that list be subjected to the capable signal controlling of the 2nd row, thereby finish the demonstration of the 2nd row, circulation is gone down only to finishing all row demonstrations according to this, the pattern that such width of cloth is made up of the bulb bright spot just has been done, and the blacking the when bright spot in this pattern is imported corresponding to pattern one by one on information carrier conceals lattice.The row of bulb are counted and to read in device identical for dot matrix, and row is counted and then can be arranged as 256,128,64 and not wait.After the 1st width of cloth pattern displaying is finished, single-chip microcomputer goes to reads the given input state of toggle switch, calculate the residence time of 1 width of cloth pattern displaying, after pattern has stopped the given time, single-chip microcomputer sends " 0 " total clear signal from one delivery outlet P1.0, this signal falls all shift registers of row, column control module on the one hand clearly, makes relay (47) action on the other hand, and its normally closed point disconnects bulb power V ₃Elementary bidirectional triode thyristor a period of time, whole controllable silicons of dot matrix are turn-offed because of current over-zero, bulb puts out entirely, whole demonstration returns to initial zero state.According to same method, single-chip microcomputer goes to the 2nd width of cloth pattern storage portions, pursues row taking-up pattern-information and send display to show after finishing all storage patterns, character demonstration, goes back to the circulation that shows the 1st width of cloth pattern again.

Pattern, character show that dot matrix is to adopt and read in device dot matrix same column and count, and columns can select into 256,128,64 for use according to customer requirements ... the bulb matrix that does not wait constitutes.Each bulb string one high-power memory cell, as one-way SCR, the silicon controlled trigger electrode is controlled by the clamp diode on the row, column line, and only at certain when the ranks line is " 1 " in a flash, the controllable silicon trigger electrode is in noble potential, by power supply V ₂The trigger voltage conducting controllable silicon that provides, bulb is lighted, afterwards no matter the ranks wire condition on the trigger electrode clamp diode how, controllable silicon is with conducting always, bulb will be lighted always, have only as power supply V ₃Power down, bulb just can be extinguished because of controllable silicon turn-offs.

By the introduction to above-mentioned the utility model technology formation and principle, we can see that it has such three big advantages: the first, and pattern, character can directly be imported, and any one can computed people all can will not use this device without study; Second because the output of this device control display message is to be designed to the serial transfer mode, so have only several lines between computer controller and the display, connection is simple, cost is low, be convenient to long-distance transmissions; The replacing of the 3rd pattern, character is very convenient, when the new pattern of input, has just washed out old pattern, the character of specifying in the figure number simultaneously.
