The invention relates to automation and computing, can be used in devices displaying sign information of automated control and monitoring systems. and is an improvement of the device according to auth.us no. 1108489,

The purpose of the invention is to improve the reliability of the device by reducing the pulsed current through the keys of the vertical electrodes of the gas discharge display panel (GUI).

FIG. 1 shows the offset of characters in the neighbor. The first lines of the symbolic information (the vertical electrode corresponding to the first fragment of the character in the even line corresponds to the space between the characters in the odd number); figure 2 is a functional diagram of the proposed device

The device contains a converter of 1 codes, block 2 of memory, character generator 3 register 4, keys of the first group 5, keys of the second group 7, ran 6, pulse generator 8, line counters 9, fragments 10 and familiarity 11, multivibrator 12 waiting, pulse distributor 13 , adder 14 and trigger 15c

The device works as follows.

The input information is recorded through the code converter 1 into the memory block 2. In the initial state, the codes of the characters, row counter 9, fragments 10 and familiarity 11 are zeroed in block 2 of memory. The waiting multivibrator 12 generates a signal that prohibits the operation of 1 generator B pulses, enables operation of the distributor 13 pulses and sets the trigger 15 to the state providing the output of logical zero to its ECO. In register 4 the codes of the last characters (last columns) are written. horizontal tires PSH 6 receive half voltage sampling signals corresponding to these codes. Distributor 13 pulses, the input of which receives codes from fragment counters 10 and familiarity-. 11 generates signals according to which the keys of the second group 7 supply the half-voltage to the vertical bus corresponding to the last fragments of the j-column familiarity.

fragments to the next state, the bus is selected, corresponding to the first fragments of the next j + 1 column familiarity in even rows and the second fragments in odd rows. Thus, with zero codes from the fragment counters 10 and familiarity 11, the semi-sampling voltage is applied to the last vertical bus

When the fragment counter moves to the single state, the first vertical tire is selected, and so on. In this way. The indicator reproduces the last fragments of characters in the odd lines of the last column of familiarity and spaces in the even lines. In accordance with zero codes from the counters of lines 9 and familiarity 11 from the memory block, the code of the first character of the first (top) line is entered. The code of the fragment number from the fragment counter 10 arrives at the first input of the adder 14. The adder 14 performs the addition of this code. the code arriving at the low bit of the second input of the adder from the trigger 15. The remaining bits of the second input of the adder 14 are connected to the zero logic potential bus. Since the trigger 15 is set to the zero state, the code from the fragment counter passes through the adder 14 without change. In accordance with this code, at the output of the character generator 3, a code between the characters is output, which is fed to the input of register 4.

After termination of the pulse from the standby multivibrator 12, which specifies the duration of the connection of the vertical bus, the generator of the 8 pulses is enabled and the distributor of 13 pulses is prohibited, so that no signal is output at its output. The keys of the second group 7 go to the closed state, at all their outputs the voltage E2o is applied. The voltage of the half-sample E1 and E2 is chosen in such a way that the potential difference E1-E2 applied to the indicator buses 6 is not enough either to occur or for maintain the bit. Therefore, the display elements of the reproduced last fragments of characters in odd lines after the deionization time has gone off.

With the arrival of the first pulse from the generator 8 in the register 4 is written

the space code, the counter of 9 lines is set to the next state, the code of which corresponds to the second line. The trigger 15 is set to one. Therefore, at the output of the adder 14, the code of the first character fragment is entered. With block code

The second character of the second line is entered into the character generator 3, which, after being converted into the first fragment code, goes to register 4. The next pulse from the generator 8 switches the counter of 9 lines and the first code of the second fragment is written to register 4. a line swarm, and the space code in the first line is shifted up. The trigger 15 switches to the zero state. To the control inputs of the character generator

3c, adder 14 is supplied with a code corresponding to the space between the characters. The output of the character generator is the code of the space corresponding to the third line. This space j and the gaps in the following lines are sequentially rewritten into register 4, with the odd lines corresponding to the gaps and even gaps to the first fragments. After filling the register, the 9-row counter activates the signal that switches the 10-fragment counter and starts the pushing multivibrator 12. The impulse from the output of the multivibrator 12 slows down the pulse generator 8, sets the trigger 15 to the initial zero state and enables the pulse distributor 13 to work. In accordance with the CE codes, the fragment counter 10 and familiarity 11 keys of the second group 7 connect the first vertical 1-indicator of indicator 6 to the common wire of E1 and E2 sources. Horizontal buses are already connected to the E1 source according to the code recorded in register 4 mc first fragments of the first characters of even lines and spaces in odd lines.

After they are displayed, the waiting multivibrator 12 is switched again,

gating the outputs of the distributor 13 pulses, which leads to damping of the burning elements of the display. Generator 8 is enabled, and register 4 is filled with the codes of the first character fragments in odd lines and the second in even lines. Their display on the indicator is carried out similarly to the first. The symbol generator 3 is programmed in such a way that when the control inputs of the codes are zero and the number of a larger number of fragments in the familiarity, the space code is inserted. During the writing to the eigister 4 of the last fragments of the first characters in the odd lines, the codes of the spaces are written in the cells corresponding to the even lines. During their playback, the familiarity counter is set to a state whose code corresponds to the second characters. The second and subsequent columns of characters are displayed similarly to the first.

Thus, in the proposed device, the load factor of the cathode keys is significantly reduced, as well as the maximum impulse current consumed from the E1 power source, which leads to an increase in the reliability of the device.
