The bus width of the device information input depends on the number of displayed characters, the “Record-read” sign and the number of familiarity on the gas discharge indicator panel 11. The bus width of the device's input of the number of device flashes depends on the maximum number of flashes set by the operator. . The first register 1 is designed to receive and store input information in the process of recording it in memory block 5. The latter is a random access memory and is intended to store the character code, the Write-read feature and the blink number code for each familiarity. The symbol generator 6 is a permanent storage device and is intended to convert the character code in accordance with the counter 15 number of fragments into the fragment code of the given character. The counters of lines 24, the number of fragments 15 and the number of familiarity 16 are intended for organizing the scanning of the image on the gas discharge display panel 11. The second register 32 is intended for storing information in read mode from memory block 5. Frequency divider 25 is designed for blinking. Adder 3 pred5

assigned to determine the number of blinks remaining. The switch 33 is intended to provide for recording into the memory block 5 information entering the information input of the device, or rewriting the information stored in memory block 5, taking into account the number of remaining flashes.

The device for displaying information 1II works as follows.

Before starting operation, the device is set to its original state by applying a reset pulse to the installation inputs of all counters, registers, t) iggers, one-shot, frequency divider 25 (not

5 is shown) and the 5 pa.m. unit is zeroed by recording zero codes at all its addresses, which are transmitted through the input bus and the bus of the number of flashes. Then, at the installation input of the device blinks number, the operator sets the binary code N of the blink number, convenient for perceiving the changing information. After that, the device is ready to receive information. Information enters the information input of the device in the form of a parallel binary code, the lower bits of which are the sign code, one bit indicates the recording (level "1) or erasing (level" O) of the image of this sign on the gas discharge indicator folder 11, and the older ones times they identify the address of his sign. An input of information is supplied with a positive polarity impulse. With its positive differential, it sets the first trigger 20 to a single state, and at the information input of the second trigger 21, the level i is set. The positive differential of the inverted signal of the pulse generator 17 (F O.,), the second flip-flop 21 goes into one state, and the positive differential of the signal at the direct output is recorded.

0 input information into the first p1 of the 1. The signal from the inverse output of the second flip-flop 21 sets the level "O at the control input of the switch 33, which corresponds to the connection of the outputs of the first

5 register 1 to the information inputs of the memory block 5, to which they receive: a sign code, a blink number code, a Write-read sign, lia B1) during groupings of the items OR 4, the familiarity address code is received, which comes from the first

0 of the output of the first register 1. In memory block 5, an inverse frequency pulse roi arrives from the output of the pulse generator through the second AND-NE.27 element and the second AND 23 element. A positive signal differential at the output of the second AND-NOT element 27 translates through the second element I 23, at the first input of which the level "1, memory block 5 is in read mode. ZlaiiHbiM positive

a one-shot 19 also starts up by a differential, the first register 1, the first 20 and the second 21 triggers are zeroed from the inverse output of which by a negative pulse. The pulse duration of the one-shot is less than half the period of the frequency of the HE. At the same time, the switch 33 connects to the information inputs of the memory block 5 the outputs of the second register 32 and the elements AND 2 of the first group and the first element AND 22 open.

Through the first group of elements AND 3 and the group of elements OR 4, the codes of the serial number of the familiarity and the lines from the counter 16 of the familiarity and the counter of 24 lines come to the address input of the memory block 5. Switching the counter 24 lines and the counter of the number of fragments 15 and the counter 16 of the familiarity are sequentially performed by pulses F1 with a direct output of the counting trigger 18. The outputs of the counters of the number of fragments 15 and the number of familiarity 16 through the decoders of the number of fragments 13 and the number of familiarity 14 control keys 12 of the second group, providing a cyclic connection of the supply voltage to the vertical tires of the gas discharge display panel P. Character codes, stored in memory block 5, from the output of its half of the character together with rows from the output of the counter 15 are converted into the character generator 6 fragments in sign code fragment. In addition, the information from memory block 5 is fed to the information inputs of the second register 32: the first input is the sign code, the second the Signal-Read signal, and the third input through the adder 31 receives the number and blink code reduced by one adder 31, since its first input is connected to levels “1.

If the code of the number of blinks at the output of memory block 5 is different from zero, then at the output of the third element And 2 a level of "O" is set. This signal, arriving at the first input of the third element AND-NOT 30, sets the first input of the first element of the AND-NO 34 level “1, and also through the second element NOT 38 sets the levels“ 1 at the second input of the first element AND-NOT 26 and the first input of the fourth element AND-NOT 35.

If the output of the frequency divider 25 is in the state "1, then the output of the fifth element AND-NOT 34 is set to level 1, which opens the second group of elements And 7, the output of which sets the fragment code from the output of the character generator 6, which is recorded by the falling edge of from the corresponding counter code 24 lines of output of the decoder 8 lines to the corresponding bits of the register group 9. This is done

by applying frequency pulses F2 through the fourth element HE 39 to the synchronization input of the decoder 8 lines. The signals from the outputs of the register group 9 are supplied to the keys 10 of the first group controlling the activation of the horizontal tires of the gas discharge display panel 11. As a result, a fragment of the sign is reproduced in the vertical bus of the gas discharge display panel 11 corresponding to the codes for the number of fragments 15 and familiarity 16.

If the output of the frequency divider 25 is in the state "O then the output of the fifth element AND-NOT 34 is set to" O, which closes the AND elements of the second group and prohibits the transmission of the character fragment code to the information input of the register group 9 and the keys 10 first groups. As a result, this fragment is not highlighted.

The frequency divider 25 is switched by a positive difference in the inverse signal from the overflow output of the 16th digit familiarity, and each time it is switched to " 1. the third trigger 40 is set to “1. If the code of the number of blinks at the output of memory block 5 is different from zero, frequency pulses F 3 from the output of the fourth element AND 29 through the open fourth element IS-HE 35 and the second element And 23 record information in the memory block 5 installed on its information inputs, while rewriting information contained in the outputs of memory block 5, and writing the code of the number of flashes, reduced by one. During the time from the moment of occurrence of level 1 at the output of frequency divider 25 to the time of the occurrence of the next counter overflow pulse, the number 16 familiarity all non-zero blinking codes of each fragment in each row and familiarity decrease by one and again recorded in memory block 5. The frequency of the signal and its duration. At the output of divider 25, the frequencies are chosen taking into account the best perception of the blinking signal by the operator.

If the code of the number of blinks at the output of memory block 5 is zero, then the corresponding input of the third element IS-NOT 30 is set to level "1, and if the second output of the second register 32 is set to level 1 (Record), then the second P group of elements And 7 is opened, the fragment code is written to the group of registers 9 from the output of the character generator 6. This occurs if this sign, after N flashes for it has passed, should remain on the gas discharge panel 11. If this symbol after N flashes should disappear , then on the second exit th register 32 is set the level of "O, which closes the second group of elements

Comm and 7 and a zero code is written to register group 9.

Consequently, on the gas discharge display panel 11, the signs that should be written after N flashes remain, and the signs that need to be erased disappear after N flashes.

FIG. 2 shows time diagrams of the operation of the device for displaying information. The case is shown when the device, after writing the input information to the memory block 5, goes into the read mode and periodically overwrites the flashing numbers decreasing by one. In this case, if the code of the number of flashes at the output of the memory block 5 is different from zero, and the output of the frequency divider is in the zero state, the information on the gas discharge display panel 11 does not pass, as. the second input of the second group of elements And 7 is in the state "O. If the output of the frequency divider is in the state "1," the level b is also present at the second input of the second group of elements And 7. If the blink number code is zero, regardless of the state at the output of divider 25, the second input of the second group of elements And 7 is in the state determined by the signal at the second output of register 32 (the "Write-read" sign). Overwriting decreases per unit codes of the number of flashes from the third output of register 32 into memory unit 5 ocynie- is switched by pulses from the output of the AND-HE element 35 in the time interval when output trigger 40 is in the state "1, and overwriting only occurs if the blink number code is different from zero.
