Abstract

The invention relates to automation and computer technology, in particular to indicator devices, and is intended to display sign information on gas discharge display panels. The aim of the invention is to simplify and expand the field of application of the device by increasing the information capacity of the device. This goal is achieved by introducing into the device additional sampling units for horizontal buses, additional panels, pulse distributor, connecting the corresponding sampling units for horizontal buses, selecting additional panels, and series-connected groups of AND elements, element OR and adder which allow access to the memory area in which the information relating to the panel to be selected is recorded. The introduction of these elements makes it possible to increase the information capacity of the device by using additional panels, but the equipment costs do not increase in proportion to the number of matrix panels. 1 il. i (lu so

Description

The invention relates to automation and computer technology, in particular to indicator devices, and is intended to display sign information on gas discharge display panels.

The aim of the invention is to simplify and expand the field of application of the device by increasing the information capacity of the device.

The device works as follows.

When inputting from signal input block 1, the recording of character codes is recorded in memory block 6 at the addresses received from input block 1 through the first element AND 2 and element OR 5. When playing information, there is no recording signal and the enabling signal comes from the output of the HE element 3 to Element And 4, We assume that the code at the output of the counter of 16 fragments corresponds to the (j + l) -My fragment, and the code at the output of the counter 17 sign corresponds to the k-th familiarity of each line. In accordance with these signals from the output of the decoder 14 fragments and decoder 15 familiarity h Through one of the keys 13, vertical bus bars of matrix panels 12, - 12 are connected to Je. Signal fragment codes written in JX vertical columns of panels 12, - 12, are recorded in registers Y-10. In accordance with the signals from registers 10, - 10, at the outputs of the keys 11, V controlling the activation of the horizontal

tires, there is a high potential, and in the J-X k-x fragments the familiarity of all the lines reproduces information. The code at the output of the counter of 23 lines corresponds to the first line, and a signal is present at the first output of the pulse distributor 24.

Since the second inputs of the elements And 19, 19 "group connected to the outputs of the distributor 24 pulses, the signal is missing, then at their outputs the signal is also missing and through the second element OR 20 to the first input of the adder 2I receives the code 00 ,,, О, Therefore at the output of the adder 21, the code corresponds to the code value at its second input, t, e, k-th. Thus, the first input of the second element AND 4 receives the code of the first line from the counter .23 lines, and the second input receives the code of the k-ro familiarity from the output of the adder 21. Since from the element NOT 3 to the first input of the second element And 4 comes the enable signal, then through the first element OR 5, the memory code 6 receives the address code of the k-ro familiarity and the address code of the first row. Accordingly, the code of the familiarity of the first line reproduced on the matrix panels 12., which goes to the generator 7 characters. Since the state of the counter of 16 fragments corresponds to (j + l) -My fragment, then at the generator output of 7 characters the code corresponds to (j + l) -My fragment of the sign. The code (j + l) -ro of the fragment from the generator of 7 characters goes to the information inputs of registers 9, 9, but it is written only in register 9 at the address of the first line coming from the decoder 8, since it receives the address code the first line from the counter is 23 lines and the enable signal from the first output of the distributor is 24 pulses. With the arrival of the next pulse from the generator of 22 pulses to the counter of 23 lines, the code on its output corresponds to the second line, C of the memory block 6 reads the sign code of the k-ro familiarity of the second line, which is converted in the generator 7 characters into (j + l) -ro fragment. Code (j + l) -ro. A fragment of the generator output of 7 characters is written into the first register 9 at the address of the second line. Similarly, the recording of codes (j + l) -x frag

cops of k-x characters familiarity of other lines in the first register 9.

After writing to the register 9, the fragment codes of all the rows, the counter 23 is set to the state corresponding to the first line. From the second output of the 23-row counter, a signal is sent to the pulse distributor 24 which transfers it to the next state when the signal appears at its second output . The signal from the second output of the distributor 24c of the information input 18, that is, the cut element AND 19 and the second element OR to the first input of the adder 21 is fed to the tsod corresponding to the first familiarity of the panel 12, j. The code at the output of adder 2 corresponds to the k-th familiarity on panel 12. The familiarity code from adder 21 goes to the second input of the second element AND 4, the first input receives the line code from counter 23, and the character code of the first line being reproduced is read from the memory block in kM, the familiarity of the first row of the matrix panel 122. Since the state of the counter of 16 fragments has not changed, the sign code in the generator is converted to 7 characters in the (J + 1) -th J) par- turement code. The code of the (j-t-l) -ro fragment from the generator of 7 characters goes to all registers 9, -9, but will be written in d

the gistro 9 at the address of the first row, since only the decoder 8 receives the signal from the second distributor output 24 pulses, With the arrival of the next pulse from the 22 pulse generator, the row counter changes to the next state and the register (9) writes the code (j + l) -ro fragment of the second line. Writing codes (j + l) -x fragments of other lines in register 9 is similar.

When establishing the distributor 24 pulses to the state when the signal is on the nth output, the first input of the adder 21 through the second element SH 20 and the element I 19 from the input 18f is given a code corresponding to

The first output of the panel 12. The output code of the adder 21 corresponds to the k-th familiarity on the panel 12. In accordance with this, the codes of the characters kx familiarity, voi-fragments, the sample block of the horizontal-produced on the matrix panel 1-2 are read from the block 6 of the memory , converting them in the character generator to the code of the (j + l) -ro fragment and writing the codes (j + l) -ro of fragments into renny buses containing the serially connected line decoder and the first register, the keys of the first group, whose outputs are connected to horizon

gistr h as from the p-th output of the distributor 24 and myco a resolution signal arrives at the control input of the decoder 8p. After writing down the 5 code of the (J + 1) -fragment of the k-ro familiarity of the last line into the register of 9 pulses, the counter 23 lines and the distributor 24 are reset. By a signal from the output of the distributor 24, pulse codes (, + 1) -th fragments from registers 9 are recorded in registers-U. The counter of 16 fragments enters the next state when the code at its output corresponds to the (j + 2) -My fragment In accordance with these signals from the output of the decoder 14 fragments and the decoder familiarity 15 through one of the control keys vertical to the common wire are connected (j-bl) -e vertical bus matrix panels 12, -12,. And reproduced information in (j + l ) -x vertical tires, and in the first registers 9, -9g, information is recorded qi (j + 2) -x fragments.

Thus, the feasibility effect is to increase the information capacity of the proposed device, provided through the use of a larger number of matrix panels, but at the same time the value of the luminance intensity of the KETOpiibix elements is retained and the costs increase disproportionately to the NUMBER of the matrix panels.
