The device contains a generator of 1 clock pulses, a driver of 2 control signals, a block of 3 delays, a generator of 4 pulses of a link, a block of 5 buffer memory, a block of 6 decoders, a first register 7 (indicator code), a second register 8 (familiarity code) , the first 9 and 10 10 30 character generators, the first 11 and the second 12 elements AND, cer 13 and the second 14 BANNERS, trigger 15, switch 16, indicators 17-1-17-n, information input 18.35

The driver 2 of the control signals contains the first counter 19, the register memory block 20, the first 21 and., The second 22 comparison blocks, the first 23, the second 24 And elements, the register 25, 40 the first element OR 26, the third element And 27, the second counter 28 , the distributor 29 pulses, a group of elements OR 30 and 31, the second element of the ШШ 32.

The first generator of 9 characters contains a shaper of 33 codes, a register 34 of the illumination code, a shaper of 35 cycles, a block 36 of the choice of micropigrams,

The X 80 and Y 81 coordinate systems. The shaper 2 of the signal control switches the operating modes of the device depending on the amount of information stored in the external memory device (OVC) (not shown) and entering the buffer memory into block 5. The amount of information is determined by the first counter of 19 words, to the counting input of which a sign of the presence of information in this ODS word arrives. The DDT, like the block 5 of the buffer memory, has the following structure. This and other memories are divided into zones, the number of which corresponds to the number of 57-1 indicators served by the device. The number of words in the zone corresponds to the number of familiarity on the screen .17-1 indicator. A portion of each memory word is assigned to a character code that needs to be displayed on a familiarity. The sign of the presence of a symbol is formed by the path. data on the inputs of the OR element of all the outputs of the bits of the memory word and the combination in the element of the signal from the output of the said element OR with a clock pulse from an external synchronization device (not shown in the drawing, as they are in the memory), Let's call these total pulses counting. Thus, the first counter 19 counts the number of characters that need to be displayed on all the micropigram code generation unit 37, the micropigram code register 38 of the 17-1 indicators during one memory polling cycle. Counter 19 The second generator of 10 characters contains a block of 39 registers of the illumination codes, a block of 40 lights, a block 41 of control signals, a block 42 of correction, a block 43 of switching, a second 44 and rei.45 distributors, elements AND 46-50, trigger 51, elements 1ЛI 52-56, first 57 and second 58 shapers otklo55

it is zeroed upon receipt of a cyclic pulse from its external sync device connected to the OVC on its zero input. The counting input of the first counter 19 is made delayed. The delay time ensures the passage of signals from the output of counter 19 through comparison blocks 21 and 22 and dasystems at coordinates X 80 and Y 81. The shaper 2 of the signal control switches the device operation modes depending on the amount of information stored in the external storage device ( TSD) (not shown) and coming into the block 5 of the buffer memory. The amount of information is determined by the first counter of 19 words, to the counting input of which a sign of the presence of information in this ODS word arrives. The DDT, like the block 5 of the buffer memory, has the following structure. This and other memories are divided into zones, the number of which corresponds to the number of 57-1 indicators served by the device. The number of words in the zone corresponds to the number of familiarity on the screen .17-1 indicator. A portion of each memory word is assigned to a character code that needs to be displayed on a familiarity. The sign of the presence of a symbol is formed by the path. data on the inputs of the OR element of all the outputs of the bits of the memory word and the combination in the element of the signal from the output of the said element OR with a clock pulse from an external synchronization device (not shown in the drawing, as they are in the memory), Let's call these total pulses counting. Thus, the first counter 19 counts the number of characters that need to be displayed on all the screens 17-1 of indicators during a single memory scan cycle. Counter 19

17-1 indicators per one memory scan cycle. Counter 19

it is zeroed upon receipt of a cyclic pulse from its external sync device connected to the OVC on its zero input. The counting input of the first counter 19 is made delayed. The delay time ensures the passage of signals from the output of counter 19 through comparison blocks 21 and 22 and further through elements 23 and 24, where these signals are combined with counting pulses from the OVC, to the corresponding inputs of register memory 20.

The current value of the amount of information in the OVC is compared with the contents of the register memory block 20. The information in block 20 may be shifted up or down by one address, with register register block 20 looped. The word block 20 consists of two parts: the left part defines some amount of information that can be in the OVC, the right part defines the code of the device operation mode. The right part of the word block 20 consists of two parts: one part containing four bits determines the choice of read pulses of a certain follow-up period, which determine the frequency of information regeneration on the screens of each of the IE 7-1 through 17-n indicators.

The other part containing N-4 bit -25 datsyi following. The first is when virgins, where N is the number of words in the block, the amount of information in the OVC and correspondingly, 20, determines the choice of one of the generations in block 5 of the buffer memory is not very large. In this case, the symbols on the screens of all 17-1 to 7-n indicators are formed by the second character generator with the average time of formation.

rator 9 or 10 characters, which forms the character). in a given period of time. In short, this part of the word defines the mode of forming characters within one or another generalized familiarity figure. In general, the structure of the right-hand sides of all N words of the register memory block 20 is as follows:

where the above parts of these words are separated by brackets, Jteva part of the zero word AO is zero.

The upper word of the register memory block 20 is operational and it defines the mode of operation of the device. Comparison unit 21 produces a single signal at its output then, Kor and the number of characters fed to its first inputs from the outputs of counter 19, exceeds the check number recorded in the left part of the upper word of the register memory 20. Comparison unit 22 produces, in turn, a single signal at its output when the number of characters supplied to its first inputs from the outputs of counter 19 does not exceed the control number recorded in the left part of the lower word of register 20

0 memory. When shifting words in block 20, the upper word becomes the place of the lower one and vice versa.

The rights part of the upper word is given in register 25. This is necessary

5 so that during the next analysis of the amount of information in the OVC, the device does not lose the previous mode of operation. The beginning of the analysis cycle is determined by the cyclic signal, by which it zeroed the counter 19 and the information in the register 25 is recorded.

The device has two modes of operation, which, in turn, are divided into a number of gradations. For the first gradation mode, the following. The first is when the amount of information in the OVC and the corresponding

actually in block 5 of the buffer memory is not very large. In this case, the symbols on the screens of all 17-1 - 7-n indicators are formed by a second generator of 10 characters with an average time of formation

In the case when the amount of information in the DDT becomes larger than the first A ,, but less than the second A, the words of the register memory unit 20, the device switches to the second gradation of the first re-. In this gradation, the device first m SShVolov displays with the average formation time, ° 7.5Td, where Td is the formation time of one element of the generalized figure. familiarity in FIG. 2, and the rest with. 5T.o.

At the same time, t, O and K, (F, t (j, .j) K ,. Considering the initial data, Kj 1334 symbols. The upper limit of the first mode of operation N, is determined at F, 50 Hz and the condition when all the characters are displayed, with an average time Cf, 7.5 T. O therefore N 2667 characters.

In the proposed device, the increments (gradations) of the left parts of words in block 20 of the register part are made the same, i.e. N; - N5 const for all ij except the last, i.e. N n-5 Ui i The capacity of the second 28 meter is assumed to be of a different integer power two, i.e. 2., and increments are taken equal to

In the second mode of operation of the devices, when forming all symbols with an average time t „, the frequency of image regeneration changes. The device provides the following image regeneration frequencies Fj ≤ 45 Hz, b, 40 Hz, F 35 Hz, F 30 Hz. Accordingly, the values of the numbers corresponding to the given frequencies F-J will be the following 2963, N 3333, N ,, 3809, NM 4445 characters.

The number n of indicators 17-1 to 17-n of the proposed device is determined from the expression

The values calculated by the above formulas are entered into register memory block 20. Depending on the

25 speeds used in the device generators 9 and SO characters and the number of registers in the block 20 register register 1-1 these Nj values can be changed. Signals on register 25

30 determines the mode of operation of the device. The signals that determine the second, the mode of operation of the device, from the outputs a-4j, .., n of the register 25 are fed to the output of the driver 2 to the second input

35 of the generator 4 pulses, and to change (select) the frequency of the memory regeneration. Signals that are determined by the first mode of the device are fed to the inputs of the elements

40 and 3J, the second 28 counter performs the actual counting of the indication of the presence of information in the OVC (or through a polling cycle in block 5 of the buffer memory). Overflow signals from the output of the second

45 28 of the counter arrive at the input of the distributor 29 and control its transfer to other states. In the excited state there can be only one in the amp and the distributor 29. In the initial state

50 position (on arrival at the input of the distributor 29 cycle pulse) in the excited state is the first output of the distributor 29. To the second input of the first element AND the first

55 groups of elements AND 3 receives a signal from the first output of the distributor 29 and, if the device is in the second gradation of the first operation mode, then through the second 32 element OR

the signal goes further to control the operation of the first 9 character generator. As a result of the arrival of this signal, the first 2 characters are displayed with an average time T T, each, and the rest with an average time t-, If the device is in the first gradation of the first mode of operation, then zero the signals from the first p-4 outputs of register 25 through the second 32-element OR will create a control signal for operation only in 10, 10, character raters, and all symbols will be displayed with an average time t each. Similarly, for other gradations of the first mode of operation of the device, the only difference is that the number of characters displayed during the average time to is changed. In the last gradation of the first mode of operation of the device, all characters are displayed with an average time t t,

The generators 9 and 10 characters are intended to form the code sequences of the excitation functions, the symbol illumination code and the length of them. through koFiYatatopop 16 on shapers in indicators. Generators 9 and 10 characters have the ability to display characters with different quality. The generator of 9 characters forms the characters of the first type on average for the time t ″, 7.5 T, and the generator of 10 characters forms the characters of the second type on average for the time tjp 15 Td. The symbol; w of the first type is formed on the generalized familiarity figure shown in FIG. 2, symbols of the second type are on the generalized familiarity figure presented in FIG. 3. Characters of the second type have higher display accuracy.

Since the geometrical dimensions of the generalized figures familiarity of two types of characters (figs; 2 and 3) are the same and the linear speed of movement of the beam across the screen is constant, when the second type of symbols is used, the frequency of the clock pulses that control the formation of microplicrams is twice as large as with the formation of micropigraphs of symbols of the first type. At the frequency of the clock generator 1, symbols of the second type are formed, and symbols of the first type are formed at the frequency twice as Meyu. Frequency division by 2 impl

It is triggered by trigger 13. Elements And 13 and BAN 14 are used to select clock pulses according to the signal from the control output of the driver. And 11 and BAN 12 are the elements for selecting the Start signal.

The switch 16 is designed for.

switching code sequences of excitation functions, illumination code, signal End of symbol on indicators 17-i.

9 character generator designed

to generate control signals to form the symbols within the generalized familiarity figure shown in FIG. 2. The 9-digit generator implements the method of micropigram image synthesis. Images are formed on 12 micro polygrams. Symbols are synthesized by four non-intersecting micropigram subsets, and each group has three micropigram sets. Therefore, the digit of the code of the micropigram set received from block 6 of decoders is four, of which two higher bits correspond to the code of the group of microplicrams, and two of them are the set of micropigrams required to form a symbol from this group. Code highlighting also

comes from block 6 decoders and does not exceed twelve bits. Register 38 of the micropigram code records a four-digit code. In register 34, the code.

twelve bit code illumination. The micropigram code generation unit 37 is designed to form the positional code of the set of micro polygrams and features of the first micro polygram of the set. Micropolygram selector 36 is designed to sequentially input signals to form only the required micropigram of this set.

and to form a signal for the duration of the operation of the forwarder 35 yogoslov. The inputs of the nikopoligram choice unit 36 are received from the outputs of the microsample code generation block 37, the signals of the micropole c4 codes involved in the synthesis of the symbol, and the signs of the first micropigrams of this set. Shifting is output from the output of 35 cycles.

The micropigram selection unit 36 is reset to the initial state at the end of each symbol synthesis cycle by the end generation signal that is received from the switch 16. The cycle imager 35 is designed to provide a series of clock signals necessary for generating the excitation functions and generating the control signal to block 36 micropigram selection. Since six-, five-, and four-element micrographs are used, the shaper of 35 cycles produces a series of clock signals of six, five, and four cycles, respectively. In the initial state, the shaper 35 is also set from the signal end signal generation signal from the switch 16, the shaper 33 of codes is designed to form the excitation functions (code sequences that control the shaper 72 and 73 deflection voltages), to the input of the shaper 33 of the codes The signals of the micro-polygram numbers are received from the micro-polygram selection unit 36 and the control strokes from the imaging unit for 35 cycles.

Generator; The 10 characters are intended to form characters within the polygram shown in FIG. 3 "This polygram is broken into four micro-polygrams. Each micro-polygram consists of ten elements and is rotated 90 ° relative to each other in space. The information description of each character is 32 bits. 8 bits are allocated to each fragment of the image. The fragment description is broken down into

two sexes (four digits each). In the 10-digit generator in block 40, the illumination does not include the parallel conversion of each field into five-bit fields, which together form a ten-digit fragment illumination code. Using the 32-bit information description of the symbol code instead of the 40-bit code simplifies block 6 decoders. Symbol generation begins the tr element of the fragment, whose illumination code is 1. In the generator, 10 characters to convert the electron beam to the trajectory point of the contour of the polymigram, with which begins30

from its formation, the period, Td IU / Vdu of impulses coming from the output of the second 14 BANNER element, is retracted. During the time T, one element of the micropigram is formed, therefore, in the 10-character generator, the zero tails of the illumination codes are considered, only starting from the two first bits of the illumination code

Micropigram formation is carried out sequentially, starting with the first fragment and ending with the fourth. Each output of the third distributor 45 is assigned its own fragment. At this time, only one output of the third distributor 45 can be in the excited state. This distributor 45 is controlled by signals from the output of the ninth element And 49.

In order to form all four fragments (micropigram), only two types of deflection voltage are needed - 5 voltages, which can be designated as A and B. The first driver 57 deflection voltages produce a voltage of type A at the output, and the second driver 58 deflection voltages - type B. A type voltage A is formed by applying to the summing input of the shaper 57 signals from the first, second fifth and sixth outputs of the second distributor 44 through the - element OR 53, and to the subtracting input - from the third, fourth, nine that and de outputs of the distributor 44 through an OR gate

54. Voltage, type B is formed by applying to the summing input of the second .. shaper 58 deflection voltages through the sixth element OR 55 signal from the second, third, seventh and eighth outputs of the distributor 44, and to the subtracting input - through the element OR 56 signals from the fourth and fifth outputs of the distributor 44. The diverting voltages of types A and B are formed by inverting the voltages A and B, respectively, with the first 60 and second 61 inverters. The selection of the required pair of deflection voltages on the Y and X coordinates (see table) is carried out by the switching unit 43 in accordance with the kind of micro-polygram to be formed.

The display of characters is carried out under the action of the code of the light coming from the output of the trigger 51. On

, one

Each cycle of operation of the distributor 44 into the backlight unit 40 is entered into an eight-bit fragment code, which is converted into the ten-bit backlight code into the backlight unit 40. Under the action of this code, only those elements of the polygram that form the symbol image are highlighted. The first - third outputs of the distributor 45 are connected to the inputs of block 39 of the backlight code registers for overwriting the next micro polygram of the backlight codes of the backlight of the next micro polygram 44. The overwriting is performed by a signal from the output of the And 49 element. the input of the third distributor 45 is made delayed for the time required for overwriting information from block 39. of the highlight code registers into the highlight block 40. The duration of the operation cycle of the distributor 44 is determined by the illumination code of the formed micro-polygram. The inverse outputs of all bits of the illumination code from the block 40 of the light are connected to the inputs of the element -A 47, which performs the operation

compare zeros. Upon completion, the overhaul is intended to store the code

This is the last necessary element of the micropigram from the output of the element. And 47 a signal is produced which sets the distributor 44 to the initial state, the first 57 and second 58 deflecting voltage generators are transferred to the state corresponding to zero voltage levels at their output, the control signal 41 returns to the initial state , resets the trigger 51 to the zero state, enters the input of the switching unit 43 to generate a signal that sets the electron beam to the starting point of the familiarity (the point where the next microgram is formed). This process is the Prep mode. In this mode, a 10 character generator is prepared to begin forming a regular micro-polygram. The return time of a CRT beam to the beginning of familiarity from any point. familiarity does not exceed the value of T. And element 48 blocks the possibility

Element And 49 allocates the pulse of rewriting the illumination code of the next micropigram from the block 39 of the registers of the illumination codes to the block 40 of the illumination, it also transfers the distributor 44 to the state corresponding to the excitation of its first output. The signal from the output of the element And 49 through the element OR 52 is fed to the input of the block 41 of control signals to ensure its operation. The same produces a Start signal, coming from the output of the BANNER 2 element to another input of the OR element 52. And element 46 serves to prevent the backlight code from shifting in the backlight block 40 in the Prepare mode. Element AND 50 serves to generate a signal. End of Symbol. This signal appears at the end of the process of forming the fourth fragment of the generalized figure (the fourth output of the distributor 45 is in an excited state) when the formation of the last element of the fourth micro-polygram necessary for the formation of the character of the element (the signal of the element 47 And 47) is completed. Block 40

highlighting the current micropigram; secondly, to shift the illumination code during the character generation process. From the analysis of the structure of symbols, it is necessary to decrypt and transform only the .5, 1 О,, 13, 1А codes received from block 39 of the highlight code registers. The remaining codes are formed by adding one zero bit. The next function of the illumination unit 40 is the formation of a shift register truncated from the younger bits. This is done in case the illumination code contains zero states in the ith low-order bits. In this case, a 10-digit generator begins to form a micropigram contour from an element whose state of the first low-order digit of the backlight is different from zero.

The control signal block 41 is designed to generate control signals that control the correction functions and the distributor 44. The control signals are generated by analyzing the inverse states of the first to ninth bits.

which are fed to the input of the block 41 of control signals from the output of the block, 4p illumination. In addition, the signals from the output of the block 41 filling signals coming to the inputs of the block 42 of the correction, which is designed to pre-; installation of the electron beam at the beginning of the contour element of the micro-polygram, from which the formation of a symbol fragment begins. There are eight possible options for starting the formation of each micro-program. Electron beam transfer to

Switching unit 43 is preassigned, first, to select a pair of deflecting voltages for each micropigram, secondly, when a situation arises when all remaining unformed micropigram elements have a zero state of the illumination code of switching unit 43 to transfer the electron beam to the beginning familiarity. Signal The end of the character prepares a 10 character generator to generate the next signal. This signal comes from switch 1b,

The familiarity selection node 75 converts the familiar coordinate code from register 8 of the familiarity code into the values of the corresponding deflection voltages, which are also fed to the corresponding inputs of adders 76 and 77 to deflect the beam of the CRT 78 to the appropriate location

screen. According to the signal at the end of the symbol, coming from the switch 16, the deflecting voltage generators 72 and 73 are reset.

The device works as follows.

In the process of regeneration of information on the screens of indicators 17-1 - 17-p information from the OVC, the post entry to the pegwy input of the former 2 and to the input

the delay unit 3, which delays the arrival of information at the second inputs of the former 2 and the buffer memory unit 5 per interval

all registers of the block 5 of the buffer memory), From the former 2 this information is fed to the counting input of the first counter 19 and the first inputs to the elec

Copies And 23 and 24. Counter 19 counts the number of symbols that must be displayed on the screens of all indicators 17-1 to 17. As the number of symbols is counted, this number is compared with the upper and lower numbers of the register memory block 20. Under the action of signals generated at the outputs of comparison units 21 and 22, in block 20 of the register memory, the words are shifted up or down. If it turns out that the left part of the top is “his words are null, and the left part of the bottom words in this case is equal to the number Njg, then both blocks 21 and 22 will have a high potential at their outputs. So that in this case the shift signal at the same time would not be generated at the outputs of both And 23 and 24, as a result of which there could be a failure in shifting the words in the register memory block 20, a single signal is provided to the inhibiting inverse input of the And 24 element from the block output 21 comparisons. As a result of this procedure, register memory unit 20 is, as it were, in tracking mode, and by the end of the OSS memory polling, the output of register memory unit 20 will be a word, the content of the left part of which corresponds to the amount of memory that will go to buffer storage unit 5 and the right one contains the code for the mode of operation. The tracking mode is terminated upon receipt of a cyclic Dashulse on the embedding input of counter 19 and the control input of the register, 25. This signal sets the counter 19 to the zero state and writes the positional code of the device's mode of operation to the register 25. Thus, the register 25 of the device's mode of operation is stored in the register 25 for information received in the buffer memory block 5 and simultaneously read from it to display the code group from the N-4th to the I-th outputs of the register 25 is fed directly to the output of the imaging device and then to the input of the generator 4 pulses to be transferred. These signals control the frequency of regeneration of the buffer memory and thereby reduce the load on the 9 and 10 digit generators. The code group from the following N-5, except the first, the outputs of the register 25 is fed to the first inputs of the corresponding elements And 31 of the first group, as well as

combines, in the OR element 26. With the help of the counter 28, the distributor 29 and the elements of the OR 30 group, signals are generated here that determine the duration of the alternate operation of the generators of 9 or 10 characters. Depending on the code taken from the outputs of the register 25, the device performs the formation of a certain part of the symbols in a shorter time. If from the first N-4 outputs of register 25 a completely null code group is removed, then the output element OR 32 also forms a zero signal, which indicates that the number of characters to be displayed does not exceed the number N and the second generator 10 displays them marks. This happens because the 12 and 14 BANCH elements are uncoupled and the Start signals and the clock sequence of the pulses of the period T required for the operation of this generator are passed to the corresponding generator inputs Yu. Now suppose that one of the first N-5, besides the first, outputs of register 25 is present

0 single potential. He through the element OR 26 otkrysha element AND 27 and passes to the counting input of the counter 28 the same pulses, which are for. the cycle has been previously counted by the counter 19. It should be noted that the cyclic pulse previously arrives at the zero input of the counter 28 and the input of the distributor 29, which is transferred to the first state, when

0 in which he is in the excited state is the first exit. In this case, the second inputs of all elements And 31 of the first group receive unit potentials, which with the specified

5 with a single potential from one of the outputs of the register 25 generates a single signal at the output of the SHSh 32 element. In this case, a 9-digit generator is connected in the same way, since elements 11 and 13 are opened and pass on the corresponding 9-digit generator inputs Start signals and a clock sequence of period pulses.

5 2To necessary for the operation of this generator. By counting 2 pulses, counter 28 overflows. and takes the distributor 29 to the second state, in which

This state is its second output. Etc. Thus, the single potential at the output of the NWP 32 is present until one of the elements of group 31 includes a single signal from the register 25 and the distributor 29. After that, the device enters the symbol display mode by the generator 10. The combined signal End of character formed at the control output of the switch 16z prepares the device for displaying the following symbol: zeroing the first trigger 15, prepares the 9 and 10-digit generators for operation, through a generator of 4 firing pulses emits a start signal,

The device performs transitions to other modes of operation according to the following rule, as long as the speed resources are allowed, then the ergonomic requirements are best provided.

not, namely, the preservation of the nominal value of 25 inputs of the first and second elements

critical flicker frequency and improved display accuracy. First, with an increase in the amount of information, the accuracy of the display begins to change (translation into a simpler structure, but less time for the formation of the alphabet of symbols). With a further increase in the amount of information, the critical frequency of flickering decreases, but not more than 30 Hz.

On the other hand, in case of failure of one of the generators 9 or .10 characters with the help of random switching (not shown in FIG. 4) information can be displayed on all or some part (depending on which generator is 10 or 9 signs functions instead of the out-of-date indicator screens 17.
