one

The invention relates to automation and computing and can be used in symbol-graphic displays in various automated control systems, control systems and information and reference systems.

Devices for displaying information that implement various methods of imaging are known. The most promising from the point of view of reliability and minimum of information, time and hardware costs for the formation of character images is the way in which sevmoly are formed from a generalized figure (polygram) fl}.

A disadvantage of the known devices is the low accuracy of reproduction of information. This is due to the fact that in these devices images are formed from generalized figures, ALLOWING ONLY to display only stylized characters that are poorly suited to the requirement of natural outlines. Improving the accuracy of displaying information by increasing the number of polygram elements and using the same methods of imaging is associated with a sharp increase in hardware and time costs.

In addition, in these devices, information is displayed with low quality and the occurrence of errors

10 C failures) in the subchannels of the formation according to the coordinates x and y when forming the generalized figures leads to the fact that starting from the element of the polygram, the formation of which occurred

IS fails, the remaining elements will be formed relative to this error, which reduces the quality of the displayed information and the reliability of imaging and in some situations

20 makes it difficult to read information from a CRT screen,

In (1), the necessary deflection functions for the formation of a complete set of micropigrams (Fig 6b) and the necessary deflection functions (according to the henna coordinates for the formation of micropigrams.  Symbols A and B denote inverted voltages A and B (table); Fig, 8 is a diagram of the distributor.  The device contains a pulse generator 1, a raster node selection unit 2, a controlled pulse distributor 3, a micro-complete selection unit 4, a deflection function generating unit 5, a modulation control unit 6, a registers unit 7, adders 8 and 9 a 1-tube tube 10 with corresponding deflection systems P and 12 and a modulator, bus 13 Offset, tires 14 Image code, 15 Start and 16 display end.  The raster node selection unit 2 contains a twenty-bit pulse distributor 17, an OR element 18, a key group 19, an OR element 20, a key group 21, an offset node 22.  registers, bus 13 offset and elements OR 23 and 24.  The micropolygram selection unit contains a four-bit distributor of 25 pulses, a group of elements And 26 ,.  key group 27, inverter 28, trigger 29, delay element 30, elements OR 31 and 32.  The deflection functions forming block 5 contains the element OR 33-35 d formers 36 and 37, inverters 3. 8 and 39, a group of keys 40 and the elements OR 41 and 42.  .  The modulation control unit contains AND 43 elements, shift registers 44, AND-HE element 45, AND 46 and 47 elements, pulse distributor 48, and OR 49 and 50 elements.  The pulse distributor (17 and 25 contains triggers 51, elements AND 52-54, Imaging, as in the known device, is performed by highlighting the elements of the complex Micro-Polygram raster.  However, in contrast to the well-known, in which micropigrams necessary for this image from a set of possible ones were formed in each raster node, and the proposed device micropigrams are needed are formed only in micropigram raster nodes specified in accordance with the raster U9LOV code.  In the proposed device, the information cost of image formation is W (ri), where q is the minimum number of raster nodes that ensures its functional completeness, Typically, q Q Q.  In the proposed device for a twenty-node-wide Micropigram growth (FIG. ba) (), q is 8.  At the same time, the full set of micropigrams that are formed in each node of the raster consists of four, five-element micropigramms, 6b, the order of formation of one of which is shown in FIG. bv  In this case .  The number of elements of the formed generalized figure {FIG.  but 131 element (.  This ensures the formation and display of information with significantly increased accuracy.  Information costs at the same time t 182 dv. ed ,, and given W 1,4 doors units on one element of the image.  The order of image formation is chosen such that after the end of the micropigram element included in the image contour, the formation of the micropigram stops and the beam is first transferred to the raster node that belongs to the world polypigrams, and then transferred to the beginning of the next micropigram of the same raster node , in the next necessary raster node.  This provides not only a significant saving of time for imaging, but also significantly improves the quality of information display due to the fact that the failure that occurs in the subchannels, the formation, affects the formation of images within the limits of that micropigram; during the formation of which the failure occurred.  in the proposed device, due to the fact that the formation of micropigrams ceases immediately after the end of the last element necessary for building the image of this micropigramme, and also due to the fact that the beam does not pass all the raster nodes as in the known, but only necessary, it provides significant savings time spent on imaging.  The raster node selection unit 2 serves to select a raster node depending on the code arriving at its input, as well as to generate a signal. End of the display, after the formation of the last element of the micro polygram belonging to the last necessary raster node is completed.  The twenty-member code of the raster nodes on the bus 14 is recorded in the corresponding triggers of the distributor 17 pulses between each of its twenty outputs and the raster node is established one-to-one correspondence.  The distributor 17 functions in such a way that in the excited (J) state of the louse there can always be only one of the outputs, the triggers 51 serve to memorize requests for the selection of certain raster nodes required for the formation of the image.  The outputs of the triggering switches 51 are connected to the inputs of the corresponding elements AND 52-54 in such a way that, with the arrival of the metering pulse, the request for the inputs of the first of the groups of elements And 52 and 53, the first of the triggers that were in state 1, is set to 0 and the corresponding pulse distribution output gl 7 connects the output of the next single trigger.  After all of your triggers are in the O state, the first request metering pulse, pass through the elements 53, is the pulse of the end of the display.  In the initial state, the output of the distributor corresponding to the first single trigger is excited.  The maximum possible number of excited outputs is eight.  The selection of a raster node is achieved in that, depending on the state of the distributor, the displacements are removed from the outputs of the OR 23 and 24 elements (respectively, for the coordinates y and x) (, 9 A. U, 2, ZL, Liu), the magnitudes of which ensure the transfer of the beam to the selected point (node) of the raster; The offset bus I3, connected to the series-connected resistors, forms the offset assembly 22, from the outputs of which the necessary offset values are taken to the corresponding inputs groups of keys 19 (y coordinate) and 21 (x coordinate).  The number of keys in the key groups 19 and 21 is determined. the number of nodes of the raster located respectively on the coordinate axis of the m y and X  The keys 19 and 21 control the signals taken from the outputs, respectively.  the corresponding elements are OR 18 and 20, the inputs of which in turn are associated with the corresponding outputs of the distributor.  For example, when converting a CRT beam into. the eighth node of the raster (Fig, 6 excited its eighth exit.  The signal taken from the eighth output through the third element OR 18 opens the third key 19, which provides passage through the OR element 23 for the coordinate of the displacement value, and through the second IL 20 element, the same signal opens the second (left) key 21, which ensures the passage through the element OR 24 (for the x coordinate) the magnitude of the displacement di.  These displacements of the input through the corresponding adders 8 and 9J declining systems of the CRT 10 transfer the beam to the familiarity point corresponding to the raster node with number 8, Two outputs of the displacement node (di, -2. 1 form another output of block 2. These displacements are necessary to select the beginnings of the corresponding micropigram in block 4.   The block serves to select only those necessary for the formation of micropigrams in the already selected raster node, for the formation of the Signal for the request for the raster node signal, and also for the generation of a signal ensuring the conversion of the formers 36 and 37 of block 5 to the initial state.  The four-digit micropigraphic code from the output of block 7 is recorded in the corresponding trigger triggers which functions in a similar way with the operation of the distributor 17 (Fig.  8) and is controlled by the signals of the micropigram request record, which is removed from one of the outputs of block 6.  Between . each output of the distributor 25 and 0 by a micro-polygram from the set of possible (FIG. 66) established a one-to-one correspondence.  The excited output of the distributor 25 means that a micropigram is formed corresponding to this output.  The signals from the outputs of distributor 25 through the corresponding elements AND 26 control the operation of block 5 and the keys 27, from whose outputs through the elements OR 31 (for the y coordinate) and 32 (for the x coordinate) are removed.  bias (remote control, 2uU - UU), ensuring the transfer of a CRT beam to the beginning of the selected micropigram.  Inverter 28 associated with one. from the outputs of the bias circuit 22 of block 2, serves to obtain the bias -DI, flip-flop 29 serves to generate a signal, under the action of which the formers 36 and 37 of block 5 are reset.  The duration of the signal taken from a single trigger output 29, o. is limited by the value of the delay element 30, the value of which is chosen based on the maximum conversion time of the formation.  telephones 36 and 37 to the initial state (ira "to, where t0 is the pulse period from the output of the pulse generator 1).  In the initial state, trigger 29 is in state O.  The magnitude of the displacements required to transfer the CRT beam to the beginning of the formation of the selected micropigram is given in the table (Fig. 66). .  The outputs of block 4j and 42 are connected via summation elements 8 and 9 to respective diverting systems 11 and 12 of CRT 10. ,  Upon the completion of the formation of the last required micropigram raster in this node from output 4 of the distributor 25, a signal is taken, which is a signal Accounting of the request of the raster node.  Block 5 is controlled by signals from the outputs of elements AND 26 of block 4, according to which the deflection, functions from the outputs of elements OR 41 and 42 arrive at one input of the corresponding adders, the other inputs of which receive offsets that determine the beginning of the formation of the selected micro polygram in the selected raster node.  Elements OR 33-35 connect the outputs 3 - (-) distributor 3 pulses to the inputs of the drivers 36 and 37 in such a way that the outputs. Lastly, the stresses of the form shown in FIG.  7  In this case, the voltage of type A is removed from the output of the driver 37, and the voltage of type B is removed from the output of the driver 37, the inverter voltages 38 and 39 of the inverter voltage are removed, respectively Ai B.  Depending on the generated micropigram, the keys 40 select the necessary forms of deflection voltages. Simultaneously with the formation of the elements of the micropigrams from output 6 of block 6, the CRT modulator 10 receives signals that control the modulation of the beam of the CRT. included in the contour of the image.  Upon completion of the display of the last required element of the micropigram from output 6.  block 6, the micropigram request accounting signal is removed.  The maximum number of micropigrams formed in a single raster node is 3, therefore block 6 contains three shift registers 44 into which the micro polygram backlight code is written from output 1 2 of block 7.  Pulse distributor 48 serves to prioritize reading of information from outputs of registers 44.  The operation of block 6 is synchronized by pulses from the output of generator 1, which are fed to one input of the elements 43 and 46. .   In the initial state, none of the outputs of the pulse distributor 48 is excited.  With the arrival of either the Start signal or the signal of the request for a node of a raster (in the diagram not shown 7, the first output of the distributor 48 pulses is triggered.  Through the element AND 47 and OR 50, the illumination code of the first formed micropigram under the action of pulses from the output of the generator 1 goes to the CRT modulator 10.  When the last of the necessary elements of the micro-polygram is finished illuminating, the signal from the output of the NE-45 element 45 is removed, allowing the next pulse from the output of the generator I to pass through the AND 46 and OR 49 element.  It is this pulse that is the pulse taken into account for the request of micropigrams.  Under the action of this pulse, the distributor of 4 pulses, the distributor 25, and the trigger 29 are transferred from the state O to the state 1, are transferred to the following states.  Block 7 is used to store the micro-polygram code and the micro-polygam illumination code in a command of the necessary raster nodes.  Since the maximum possible number of raster nodes selected during imaging is 8, the number of registers in block 7 is seven.  The reading of the code of the micropigram in block 4 and the code of the illumination of the micropigram in block 6 is performed by the Signal of the request for the raster node.  The distributor 3 operates in such a way that in the excited state, under the action of pulses from the output of the generator, only one of its five outputs can be in series.  In addition, under the action of the Signal Record of Micropigram request to the control input signal, the distributor 3 is reset to the initial state, regardless of the state in which it was before the arrival of this signal.  In the initial state, none of the outputs of the distributor 3 is excited.  The device works as follows.  On the bus 14 in block 17 and block 2 for. the code of the nodes of the raster is written, and the registers of block 7 are micropigram codes and micropigram illumination codes.  In this case, the micropigram code and the illumination code dp are three micropigrams for the first one. the required raster node is entered into block 25 and registers 44 of block 6, respectively.  The displacement bus 13 transfers the required displacement to the displacement node of the block 2, which ensures the movement of the CRT beam to any raster assembly.  In accordance with the first excited output of the raster 17, the CRT beam, under the action of bias voltages, coming from the outputs of the OR elements 23 and 24 of block 2 through the adders 8 and 9 to the deflection systems 11 and 12 of the CRT 10, is transferred to the first required raster node.  And under the action of bias voltages taken from the outputs of the elements OR 31 and 32 and fed through adders 8 and 9 to the deflecting systems II, 12 of the CRT 10, the beam of the CRT is transferred to the beginning of the formation of a micropigram which corresponds to the first excited output p of the distributor 25.  On the same signal of the Start, the pulse distributor 48 is set to the state corresponding to the excitation of its first output and the pulse generator 1 is started, which accumulates a periodic pulse sequence.  The pulses from the generator's code are fed to the input of the block 3.  The signals from the output of block 3 control block 5 in such a way that, from its outputs, depending on the excited output of the distributor 25 of block 4, voltages are removed that determine the movement of the CRT beam along the micropigram contour, which corresponds to the excited output of block 25.  At the same time with . the formation of the elements of a micro-polygram under the action of pulses from the output of the generator 1 of the pulses from the output of the first register-44 block 6 through the elements AND 47 and OR 50 to the CRT modulator 10 receives the illumination code of the micro-polygram formed.  Under the action of this code, under the glowings, only those elements of the micropigram are found that make up the B image in the aggregate.  At the end of the illumination of the j format of the last of the necessary elements of the micropigram, the output of the request of the micropigram is removed from the output of the IL 49 unit of block 6.  Under the action of this pulse, the block 3 is brought to its initial state, the distributor of micro-tacts through the delayed entry into the next state, the distributor 25 is also transferred to the next state.  By the same signal, trigger 29 is transferred to state 1, which blocks keys 27.  This ensures the transfer of the teaching CRT to the raster node, which corresponds to the first excited output of the distributor 17.  In addition, during the time T, under the action of a signal from a single output of the trigger 29, the shapers 36 and 37 of the block 5 are set to the state corresponding to the zero level of the voltages at their outputs.  After the time tT, the AND 26 elements are unblocked and the displacement levels V are removed from the outputs of the OR elements 31 and 32, ensuring the transfer of the CRT beam to the beginning of the formation of the next micro-polygram, which corresponds to the next excited output of the distributor 25 ,.  The formation of the following micropigram of this raster node is carried out in the described manner.  Upon completion of the formation of the last micropigram required, the next impulse to record the request of micropiggs through the distributor 25, in which all triggers are in the state O (all requests are taken into account), is removed from the output 45 of block 4 as the impulse to account for the raster node request.  According to this signal, the distributor I7 is transferred to the state corresponding to the excitation of the next output of the distributor 17, in accordance with the code of the raster nodes written in block 17, the Beam is translated to the next necessary raster node in the manner described.  By the same signal from block 7, the micropigram code and the micropigram illumination code are written into the blocks, respectively; the dispenser 48 is switched to the state corresponding to the excitation of its first output.  The device is ready to form the necessary micropigrams in the next necessary raster node, Transients, the processes in the device do not exceed the time t, t. e, one clock cycle 1) 1 device.  Upon completion of the formation of the last micropigram in the last node of the raster from the output of block 17 via bus 16, the imp is removed. End display.  On this signal the device is prepared. It is made to form a new image on a new acquaintance.  Thus, on the screen of a CRT, at practically the same informational, instrumental, and time expenditures as in the known device / images are formed with an accuracy far exceeding the accuracy of displaying information in the known device.  This is ensured by the fact that the formed micropigram raster has a more complex structure - and contains a much larger number of functional elements.  In order to form an image on such a complex raster, the proposed device requires only 182 dv, units. , To ensure the same accuracy by the method used in the known device, it would take 400 dv. units , and in a functional way more than 700 doors. units, on one image.  . The higher the accuracy required to display information, the more significant the benefits from the use of the proposed device and the image generation algorithm implemented in it. The quality of the displayed information in the proposed one. device is enhanced by the fact.  that the failures occurring in the subchannels of the formation affect the image formation process within a single micro-polygram.  For devices of this type, this is a significant momeite, since images are constructed from a large number of micropoly grams with a small number of elements. .  In addition, the complexity of the raster allows to significantly expand the functionality of the device, and hence the area of its application.  Invention Formula. eni 1.  A device for displaying information on the screen of a cathode ray tube (CRT) containing a pulse generator, whose input is connected to the Start bus, and an output to one of the inputs of the first pulse distributor whose outputs are connected to one of the inputs of the deflection function forming unit The outputs of which are connected to the Inputs of the corresponding adders, the outputs of which are connected to the corresponding deflection systems of the CRT, the modulator of which is connected to the first output of the modulation control unit, the first output of which is connected to one from the outputs of the register block, one input of which is connected to the splinter Image code, bus End of display, micropigram selection block, one output of which is connected to the deflection function generating unit, characterized in that, in order to increase the accuracy and speed of the device, a raster node selection unit, one of the inputs of which is connected to the register unit and the second output of the micropigram selection unit, the first input of which is connected to the second output of the raster node selection unit, the third and fourth outputs of which are connected corresponding to the second inputs of adders, whose third inputs are associated with respective passages you mikropoligramm selecting unit, the second input of which is coupled. with the second output of the register unit, and the third, input with the other inputs of the deflection function forming unit and the first pulse distributor, as well as with the output of the control unit for the remote control, the other input of which is connected to the output of the pulse generator.  016 2.
