The invention relates to automation and computer technology and can be used in devices designed for input-output of information from the screen of a cathode ray tube into an electronic computer.

A device is known comprising a display with at least two cathode ray tubes, large. the number of controls associated with each graphic information reproduction unit, a control unit included between the controls and reproduction units [11.

Closest to the technical nature of the proposed device is a device for inputting and outputting information, containing keyboard input blocks, visual indicators on cathode ray tubes, blocks of location indicators for each visual indicator, word erase keys, size. 2 words, erasing a line in each of the keyboard input blocks (21.

A common disadvantage of the known devices is their limited scope due to the fact that ⁵ in the interaction of a group of operators with a complex image reproduced on the screen of a single cathode ray tube (complex drawings of the designed objects, the air situation in the area of a large airport, the structure of a large molecule) uses one pointer sensor and one functional keyboard for all operators. The use of individual on-screen remotes with a follow-up visor sensor and a functional keyboard for each operator leads to unreasonably high hardware costs, and sometimes it is generally excluded when operators must collectively discuss situations that arise, and at the same time, each onepatop must independently interact with other operators ^{3 9115 Choose a} reproducible image.

The purpose of the invention is to simplify the device.

. This goal is achieved by the fact that the device for input and output of information containing a serially connected control unit, the first input of which is connected to the input bus, an image memory unit, an image generator, a video amplifier and a cathode ray tube (CRT) connected with a deviation control unit, which is connected to the output of the image generator, the output j of the control unit is connected to the output bus, and the second input is to the output of the image memory block, the sensor block is connected in series a live viewer, the input of which is connected to the input control bus, a comparator unit, a follower sight discriminator, an encoder, a follower number memory block and a tag georator whose output is connected to the second input of the Image Generator, an editing unit, one input of which is connected to the input control bus, and the output is to the third input of the control unit, the block of OR elements, the input of which is connected to the output of the follow-up discriminator, and the output - to the fourth input of the control unit and the second input of the follow-up discriminator and yield * '' which is connected to the second input .bloka memory numbers reticle follower whose output is connected to a fifth input of the control unit and the second input editing unit generator voltage input is connected to the control deviation vyhodubloka; and the output is to the second input of the comparator unit, the output of which is connected to the third input of the image generator through the generator of the tracking sight.

In FIG. 1 shows a block diagram of the proposed device for input and output information; in FIG. 2 is a circuit diagram of a block of comparators; in Fig., 3 is a circuit diagram of a discriminator ^{1 of the} tracking sight.

The device of FIG. T contains a control unit 1, an image memory unit 2, an image generator 3, a video amplifier 4, a deviation control unit 5, a cathode ray tube 6,

4 voltage shaper 7, tracking sensor 8 sensor unit 8, comparator unit 9, editing unit 10, OR element block 11, encoder 12, tracking device generator 13, tracking device number memory unit 14, tag label generator 15, tracking device discriminator 16, bus 17 input information, the output information bus 18, the input control bus 19, the input 20 and 21 and the output bus 22 of the comparator unit 9, the input 23 and 24 and the output bus 25 of the discriminator 16 of the follower.

Block 9 of the comparators (Fig. 2) contains, for example, for the case of playing four pointers simultaneously on the cathode ray tube '6 screen simultaneously), comparators X 26-1, 26-2, 263 and 26-4, comparators U 27 “1, 27 * 2, 27 * 3 and 27-4, elements And 28-1, 28-2, 28-3 and 28-4.

The discriminator 16 of the tracking sight (Fig. 3 ') contains the elements And 29 * 1, 29 * 2, 29 * 3 and 29 * 4, waiting for the multivibrators 30-1, 30-2, 30-3 and 30-4, the elements And 31 * 1, 31 * 2, 31 * 3 and 31 * 4.

The proposed device operates as follows.

Input information (commands and data) from the bus 17 through the control unit 1 is recorded in the image memory unit 2.

The control unit 1 is a MiliMur type hardware machine or / and a Wilks type firmware that generates a sequence of output (control) signals in accordance with a sequence of input (informative) signals and the law of operation of the machine, predetermined by the firmware.

The image memory unit 2 is a random access memory, for example, ferrite or semiconductor. The number of addresses of block 2 of the image memory is determined by the maximum number of elements (characters, vectors) that can be simultaneously displayed (on one frame) on the screen of the cathode ray tube 6, and the number of bits of block 2 is determined by the length of the element code.

The element codes read from the block 2 of the image memory are fed to the input of the generator 3 images, which converts these codes into

911503 6 pulses of modulation and voltage deviation of reproducible elements.

• The image generator 3 is a passive storage device, for example, ferrite or _5- semiconductor.

The modulation pulses from the output of the image generator 3 through the video amplifier 4 are fed to the cathode ray tube modulator 6, for example, a standard picture tube, and the deviation voltages through the deviation control unit 5 expand the reproduced image on the cathode ray tube screen 6. 15 the deviation control unit includes deflectors amplifiers X and Y and deflection coils X and Y.

Each of the operators (bus 19), independently of the other operators, interacts with an arbitrarily selected fragment (one element or a set of elements) of 6 images displayed on the cathode ray tube screen using an autonomous 25 follow-up sensor of the follow-up sight sensor unit 8 . The number of sensors of the tracking sight in the block 8 of sensors of the tracking sight _{t is} thus greater than or equal to the number of zo operators editing the reproduced image.

Each of the pointer indicators of the tracking sensor unit 8 of the tracking sight sensor is a two-coordinate potentiometer, one of the output voltages of which is proportional to the offset of the tracking sight on the cathode ray tube screen in the X coordinate, the second in the U coordinate.

To indicate the editing function (erase, mark, shift, etc. image fragment), each of the operators has its own standalone keyboard included in the editing unit 10. Each operator sets the sequence of editing functions in accordance with the task he is solving, independently of other operators.

The voltage from the output of the sensors of the pointers of block 8 of the sensors of the tracking sight enters the inputs of the comparators of block 9 of the comparators, the other inputs of which receive voltage from the output of the shaper 7 voltages.

The voltage generator 7 generates voltages proportional to the deflection currents in the deflection coils X and Y of the deflection control unit 5. To do this, a resistor is connected in series with each of the deflecting coils X and Y, from which the corresponding voltage is removed. The resistance value of the resistors is chosen much less than the intrinsic resistance of the deflecting coils X and Y, so that the resistors practically do not affect the parameters of the deflecting currents. If necessary, voltage drops across the resistors can be amplified by amplifiers included in the form of a voltage transformer 7.

At the time of comparing the voltage from the sensor of the tracking sight of the block 8 sensors of the tracking sight, proportionally to the position of the tracking sight horizontally, with the horizontal scan voltage from the output of the voltage generator 7, the voltage of the pointer sensor, proportional to the position of the pointer vertically, with the vertical voltage, at the output block 9 of the comparators is formed by the pulse of comparison. The number of comparison channels inside the block 9 of the comparators and the number of output circuits of the comparison pulses from the output of the block 9 of the comparators is equal to the number of sensors following. of the target in the block 8 of the sensors of the tracking sight, i.e. each of the sensors of the tracking sight has its own independent channel for the formation of a comparison pulse.

The comparison pulses from the output of block 9 of the comparators are fed to the inputs of the generator 13 and discriminator 16 pointers.

For each reference pulse, the tracking target generator 13 generates pulses of modulation of the deviation voltage, with which a tracking target of various configurations (crosshair, circle, 'Scientific', ¹ , etc.) is reproduced on the screen of the cathode ray tube 6, which is unambiguously associated with appropriate pointer sensor. Fortunately · 'giving this, each of the operators is convenient to follow their pointer.

The tracking sight generator 13 nd functions and design is similar to the image generator 3 and is connected to the image generator 3 so that through the image generator 3 is connected to the modulation and deviation circuits common to both generators 3 and 13.

911 503 ⁸

When the tracking sight is superimposed on the screen of the cathode ray tube on top of each other for the correct functioning of the encoder 12, it is necessary that only one pulse of comparison arrives at the EPO input. If the pointers are not superimposed on each other, all the comparison pulses arrive at the input of the encoder 12. This problem is solved by the discriminator 16 of the tracking sight, the functioning of which will be described in detail below.

The encoder 12, which is a converter of the input unitary code to the output positional one, assigns to each bus from the follow-up sensor of the follow-up sensor unit 8 of the follow-up sensor sensors arriving at its input through the comparator unit 9 and the follow-up discriminator 16, corresponding to its 20 binary bus number code in those times when one of the input buses is excited by the corresponding comparison pulse.

A block of 11 elements, representing 25 an OR element, combines all the comparison pulses arriving at its input into one common signal. The total signal supplied to control input unit 1, a sign ₃₀ starts processing informa- tion from the output of the corresponding sensor unit 8 reticle servo tracking sensors reticle.

It should be noted that since beam ₃₅ yawing image screen of a cathode-ray tube 6 at any given time is only to a certain single point on the screen, and therefore, at any given time can exist must only one ₄₀ request service pointer sensors (interrupt), then the hardware amount. related to the queuing service datchi- sensor unit 8 pointers and pointers ₄₅ Cove required in similar cases for storing interrupt requests, interrupting maksirovaniya s and isolating interrupt with the highest priority, are virtually absent. All pointer sensors thus have the same priority and are serviced for a time equal to one frame of the image reproduction, for example, at a frequency of regeneration of the reproduced image of 50 frames / s per 20 m. At this time, each operator interacts with 6 electron-beam tubes reproduced on the screen 6 image as if it interacts with the reproduced image alone. Uncertainty in a rather rare si. The tutuations of overlapping at least · two pointers (the operators each interact with their own image fragment, and the fragments are spaced) are eliminated by the discriminator of 16 pointers.

The number of the activated pointer sensor from the output of the encoder 12 is recorded in the block 1u of the numbers of the tracking sight.

The tracking unit number memory unit is a random access memory device, for example, ferrite or semiconductor, with the number of addresses equal to the number of addresses of the image memory unit 2 and with the number of bits in the recorded word equal to the binary logarithm of the number of pointer sensors in the block of 8 pointer sensors.

Addressing the memory blocks of images 2 and the numbers of the tracking sight 14 is carried out by the control unit 1 in parallel. Therefore, the code of the Image Element in the block 2 of the image memory · and the code number of the tracking sight in the block 14 of the memory of the numbers of the tracking sight interacting with this picture element are always uniquely associated.

Read from the block 14 memory numbers of the tracking sight, the code of the sensor number of the tracking sight is used to gate the functional keyboards of the editing unit 10. All functional keyboards of the editing unit 10 have one common output, and the strobing of the functional keyboards makes it possible to uniquely identify the signals from the output of each functional keyboard. These signals (editing functions) are recorded in block 2 of the image memory through block 1 control. ...

The code of the image element together with the code of the editing function from the output of block 2 of the image memory and the code of the number of the tracking sight from the output of block 14 of the memory of the numbers of the tracking sight through the control unit 1 and bus 18 are transmitted to the digital information receiver for further processing.

The tracking number number code from the output of the tracking unit number memory block is also input to the gene

9I503 Ό of the radiator 15, which generates labels for the editable image elements that are characteristic of each sensor of the index pointer, which are distinguished by brightness, shape, blinking, color. The generated ₅ mark signals through the image generator 3, the video amplifier 4 and the deviation control unit 5 are supplied to the cathode ray tube 6.

The tag generator 15 is a passive storage device, for example, ferrite or semiconductor.

For each pair of comparators 26 and 27 of the unit 9 of the comparators (Fig. 2), voltages Ih and Ii from the corresponding pointer sensors of the block 8 of the pointer sensors are received. The second inputs of the comparators 26 are supplied with voltage. Their horizontal scan, comparators ₂₀ tori 27 “voltage Yi vertical. The outputs of each pair of comparators 26 and 27 are connected to the elements And 28.

Comparators 26 and 27 can be performed on the basis of 1UT401B type operational amplifiers commercially available from industry, I elements based on 155 series of elements;

, Through the elements And 29 of the discriminator 16 of the tracking sight (Fig. 3), the signals associated with the bus 24 pass when there is a resolving potential on the bus 23. The signals from the outputs of the And 29 elements trigger the waiting multivibrators _3J 30, generating pulses of a given duration, which through elements And 31 enter the output bus 31.

The use of new elements - ₄₀ voltage shaper, sensor unit of the tracking sight of the block of comparators, block editing of the block of elements OR, encoder of the generator of the tracking sight, memory block numbers of the tracking sight, tag generator and discriminator of the tracking sight compares the proposed device for inputting and outputting information from the known as it expands the scope of the proposed device due to the possibility of collective interaction of a group of operators with one played on the screen ele cathode ray tube image using the sensors of the tracking sight while reducing hardware costs - no interrupt unit is needed.

The sensors of the tracking monitor are serviced automatically by self-service.

P.  a fragment of the image) each of the operators has its own autonomous keyboard, included in the editing block 10.  Each operator sets the sequence of editing functions in accordance with the task it solves, independently of other operators.  The voltage from the output of the sensors of the indicators of the block 8 sensors of the following viewfinder is fed to the inputs of the comparators of the block 9 of the comparators, the other inputs of which receive the voltages from the output of the driver 7 of the voltages.  The voltage driver 7 generates voltages proportional to the bias currents in the deflecting coils X and Y of the deviation control unit 5.  For this, a resistor is connected in series with each of the deflecting coils X and Y, from which the corresponding voltage is removed.  The resistance value of the resistors is chosen to be significantly less than the intrinsic resistance of the deflecting coils X and Y, so that the resistors have practically no effect on the parameters of the deflecting currents.  If necessary, the voltage drop across the resistors can be amplified by amplifiers included in the voltage driver 7.  At the time of comparison eg g.  from the sensor of the sighting reticle of the block B of the sensors of the sighting reticle, pro. proportionally to the position of the next traversal on the horizontal, with the horizontal voltage from the output of the former 7 voltages, and the pointer sensor voltage proportional to the vertical position of the pointer, with the vertical scanning voltage, at the output of the comparators 9 formit.  Route impulse comparison.  The number of comparison channels inside the comparators block 9 and the number of output comparison circuits from the output of the comparators block 9 are equal to the number of sensors followed.  the sight in the block of 8 sensors of the following viewfinder, t. e.  for each of the sensors of the servo sighting device, there is its own independent channel for the formation of a comparison pulse.  Comparison pulses from the output of block 9 of the comparators are fed to the inputs of the generator 13 and the discriminator 16 pointers.  A follower sighting generator 13 for each comparison pulse generates modulation and deviation voltage pulses, which are used to reproduce the next sighting device of different configurations on the screen of the cathode-ray tube 6 (cross, circle, loutch, and so on. P. ) uniquely associated with a corresponding pointer sensor.  Good-; a gift to this, each of the operators is convenient to follow their pointer.  The generator 13 of the follow viewflf functions and design is similar to the image generator 3 and is connected to the image generator 3 P in order through the image generator 3. connect to the common for both generators 3 and 13 modulation and deviation circuits.  79 When the follow-up viewfinder is superimposed on the screen of the cathode-ray tube on each other, in order for the encoder 12 to function properly, it is necessary that the input of the input should have only one comparison pulse.  If the pointers are not superimposed on each other, all comparison pulses are sent to the input of the encoder 12.  This problem is solved by the discriminator 16 of the follower, the operation of which will be described in detail below.  The encoder 12, which is a converter of an input unitary code into an output positional code, assigns to each bus from the sensor of the follow sighting unit 8 of the follower sighting sensor unit 8 that arrives at its input through the comparator unit 9 and the discriminator 6 of the following sighting device, corresponding to its binary code of the bus number those times when one of the input buses is excited by the corresponding comparison pulse.  An AND block, which is an OR element, combines all comparison pulses at its input into one common signal.  The common signal is fed to the input of control unit 1 as a sign of the start of information processing from the output of the corresponding sensor of the follow sighting unit 8 of the follower sighting unit 8.  It should be noted that since the beam that expands the image on the screen of the cathode-ray tube 6, at any given time is located only at one point on the screen, and thus, at each given time, there is only one sensor service request pointer (interrupt), the hardware costs associated with the organization of the queue for servicing the sensors of the block of 8 sensors of the indicators and necessary in similar cases for storage. Neither requests for interrupt, max interrupt, and interrupt allocation with the highest priority are practically absent.  All pointer sensors thus have the same priority and are serviced for a time equal to one cEDal of image reproduction, for example, at a reproduction frequency of the reproduced image of 50 frames / s per 20 m.  At this service time, each operator interacts with the image reproduced on the screen of the electron-beam tube 6 as if it interacts with the reproduced image alone.  The uncertainty in a rather rare situation, the overlapping of at least two pointers (the operators each interact with their own fragment of the image, and the fragments are spaced apart) is eliminated by the discriminator 16 of the pointers.  The number of the activated pointer sensor from the output of the encoder 12 is recorded in the memory block 1 of the tracking reamer number.  The memory unit of the tracking reticle is a random access memory, for example, ferrite or semiconductor, with the number of addresses equal to the number of addresses of the block 2 of the image memory, and with the number of bits in the written word equal to the binary logarithm of the number of pointer indicators in block 8 sensors pointers.  The addressing of the memory blocks of the images 2 and the numbers of the follow sighting 14 is carried out by the control unit 1 in parallel.  Therefore, the Image Element code in the image storage unit 2 and the code of the next reticle in the Block And the memory of the numbers of the subsequent reamer that interacted with this image element are always uniquely associated.  The code of the tracking visor sensor, read from the memory module C of the tracking servo sighting sensor, is used for gating functional functions of the editing unit 10.  All the functional keyboards of the editing unit 10 have one common output, and the gating of the functional keyboards allows unique identification of the signals from the output of each functional keypad.  These signals (editing functions) are recorded in block 2 of the image memory through block 1 of control. . . .  The code of the image element together with the code of the editing function from the output of the image memory unit 2 and the code of the tracking reamer from the output of the memory block k of the tracking reamer via the control unit 1 and the bus 18 are transmitted to the digital information receiver for further processing.  The code of the following trackfinder from the output of the memory block of the follower tracer numbers is also fed to the input of the generator 15, which forms for the edited image elements characteristic marks for each indicator of the pointer differing in brightness, shape, blinking, color.  The generated mark signals through the image generator 3, video amplifier k and deviation control unit 5 are fed to cathode ray tube 6.  The tag generator 15 is a passive memory device, for example, ferrite or semiconductor.  For each pair of comparators 26 and 27 of the comparator unit 9 (FIG.  2) They and Yiwu stresses come from the corresponding sensors of the indicators of the block of 8 sensors of the indicators.  The second inputs of the comparators 26 are supplied with the voltage Their horizontal scan, the comparators 27 - the Yiwu voltage the vertical sweep.  The outputs of each pair of comparators 26 and 27 are connected to the elements And 28.  Comparators 26 and 27 can be made on the basis of commercially available commercially available type amplifiers, elements AND based on the 155 series of elements;
