(54) DEVICE FOR DISPLAYING A SYNOGRAPHIC

I

The invention relates to computer-assisted teo-technology and can be used in devices for displaying information on infrastructures built on ga-rous AC inertial panels.

Display devices are known to use a gas discharge display panel of alternating current as an element of nvdikacin. These devices are executed with both parallel and serial output of the information 11.

Devices with a permissive output of information have a higher speed in comparison with devices of sequential output of external information and therefore allow to increase the volume of sign information of both the mobility of all and part of the displayed elements.

The significant shortcomings of these devices — the complexity and cumbersome addressing schemes of the electrodes of the gas-discharge display panel — have significantly increased the required current during recording and

as a result, the reliability of the whole device is low and its weight and dimensions are high.

Devices with successive water information have a simpler addressing scheme for gas discharge electrodes. Understand the individual panel and menopm by the required current in the recording mode, and therefore have greater reliability and better weight and dimensional characteristics.

The disadvantage of such devices is the low speed in the mobility mode of both all displayed elements and their parts. And this, in turn, limits the volume of output of the audio graphic elements on the screen and, as a result, the field of application of devices

Most of the technical essence is the 1DF (M) (a device containing a synchronization block, a memory block, a buffer register, an address register, an interpolator, a yes code, an instruction code descriptor, a block, a record, a read block, generator, outgoing X and Y registers, gas discharge indicator panel 2

The disadvantage of the known device is the gradual volume of displaying the signographic information with the subjectivity of both the entire image and its individual elements due to the low speed during the sequential input of the infs; 11аии.

The purpose of the invention is to increase the speed of the device.

This goal is achieved by the fact that

And its counting number is connected to the outputs of the first, second and third decoders, the input of the third decoder is connected to the outputs of tt pvo1CH "of the second memory blocks, and the output to the input of the synchronous block 1pa, the third output of which connected with VK House second reading unit inputs kommutansh mounting unit of the first and second memory blocks of n input co-ij alone are {& 1 with the output of the comparison unit, the first input of which and the second input of the second address register are connected to the inputs of the second buffer register, the second input of the comparison unit is connected with the output s0 of the second address register with the third input of the third memory, the third input of the comparison unit is compressed with the output of the second reading unit and the first inputs of the second address register and the third; its memory block, the second input of which is connected to another output of the interpolator, and the output to the input of the fourth decoder, the first output of which is connected to the input of the interpolator, the first input of the second buffer register is connected to the outputs of the first and second memory blocks, and the second input - to the second output of the fourth decoder.

The drawing shows a block diagram of the device.

The device contains a synchronization unit 1, a first memory block 2, a second memory block 3, a gas discharge indicator panel 4, a third memory block 5, a first buffer register 6, the first address register 7, a switching unit 8, a recording unit 9, the first decoder 10, first read block 11, second decoder 12, interpolator 13, first and second output registers 14 and 15, third decoder 16, second buffer register 17 second read block 18, block 19 & second address register 2O, generator 21 and the fourth deshi (mtor 22.

The device works as follows.

Synchronization unit 1 forms the time cycle of the entire device. This cycle includes the following subroutines: subroutine of erasing the old in writing new operational information {from the computer to the first memory block 2, subroutine reading the old operational information from the second memory block 3 for moving signographic elements from the screen of the discharge display panel, - 4 subroutines for reading new information from the first memory block 2 for recording moving character elements, as well as for resuming erased points of non-memory; Vizny e-tapes of signographic information; a sub-diagram of reading non-operational information from the third block of 5 Memory for resuming the erased points of the still elements of the image.

The sequence of execution of the subroutines specified by the synchronization unit 1 is determined by the condition of the minimum time spent on moving the image elements recorded in the previous time cycle and on writing the moving elements in the current cycle. The same condition imposes a requirement on the placement of information about moving elements in the first cells of both blocks 2 and 3 of the memory, in connection with the fact that during successive erasure the point behind

the point of the moving picture elements the execution of the subroutine ends after the selection of the last word with mobility signs from one of the blocks 2 and 3 of the memory; similarly, when recording moving elements, information about moving images is first sampled from the corresponding block 2 and 3 of the memory, and then fixed. Therefore, with arbitrary filling of memory blocks 2 and 3, additional time and information search with a sign of mobility is lost. Reproducing the fixed elements of operational information in each cycle of operation of the entire device allows you to resume separate overlapping points of moving and fixed elements, written off from the memory of the gas discharge display panel 4 in the process of erasing the moving image elements. In the same way, the erased points are resumed during the reproduction of the fixed elements of non-operational information recorded in the memory block 5.

In the cycle cycle, synchronization block 1 generates the command Query of the information array. For this comaid, a code word enters the input of the first buffer of the register 6 from the external evaluator that contains information about the feature (instruction) of the element: vector, arc, circle marker, siack} about the coordinates of the control points of the elements, about the mobility of the elements to the input buses. address register 7 receives information about the address of the entered word. Each input word is accompanied by the command Enter. According to this command, the synchronization unit 1 n), with the front of the formed pulse, launches the recording unit 9. As a result, the output of the recording unit produces a sequence of commands. 1 On the first command, the first buffer status 6 and the address 7 registers are set to the first state. In the command line, the address code of the input word is written to the address register 7. The third Write command clears the information from the cell of the first memory block 2 in accordance with the code of the address register 7 and high potential at the single output of the switching unit 8 (trigger). The fourth command sets in-buffer register 6 in one code. With this command, the Record into the freed cell of the memory block 3 is written the information on the memory. By the sixth command, the writing unit 9 is reset to the initial zero state. Similarly, the input into the corresponding memory blocks of all the words of the information array is performed. The end of the input of the information is accompanied by a code that is converted by the first decoder Yu to ({potential potential arriving at the trigger input 8. As a result, the trigger is transferred to the opposite state, and thus the first memory block 2 is turned off, which just before the updated information was recorded, and a second memory block 3 was connected with non-updated information.

Upon the command End of input from the output of the decoder 10 to the input of the synchronization unit 1, a signal appears at its output that triggers the first reading unit 11, the execution of the readout subroutine from unit 3 of the moving image elements to be erased begins. Information about these 9p & The cops occupy the first cells of B1 3, starting with zero. Simultaneously, the KOMatida End of input sets the address register 7 to the state O. The first one from the set at the output of the reading unit 11 reads the code of the moving element and the instruction code from the cell of unit 3 at the zero address.

A high level from the output of the decoder 12 triggers the interpolator 13, at the output of which a sequence appears. According to the first command from the second exit, ipterpol tsfa ocyraecTansieTCH, a sample from block 3 of the spacing X and At the reference point of the erasable element (vector, arc, tsrug, marker, sign). The second mand will receive the input of the address register 7 and increase its contents by 1. The third command selects a block of 3 coordinates X and Y of the second reference point of the element to be erased at the address different from the previous one on. The fourth command affects the input of the address register 7 and increases its contents by 1,

If the list of control points of the erasable element is more than two f, then the sample from the code of the coordinates of these points from block 3 and the subsequent increase in the content of the address register 7 by 1 continues.

After the termination of this process, the inter face 13 produces the formation of intermediate points of the element to be erased. The codes of the coordinates of these points are recorded in the output registers X 14, 790 U 15. sequentially in time, synchronous with the after-performance of pulses, wvsch}, supporting the discharge of the gas discharge double indicator panel 4. After all points of the ignition element to be transformed, on the second input of block 1 of the blue sky from the first interpreter 13, a command is received to end, Under the action and this command, the output of block 1 of the launch of block 11 of the screen 11 will appear.

The signal from the output of the low 4 on the clock 12 steps on the accounts of the trigger entry 8. It is thrown into the rotary state, thereby disconnecting the first memory block 2 and connecting the second block 3 of memory, which means that this block is ready to execute the subroutine nor write. Moreover, the signal from the output of the decoder 12 acts on the first input of the synchronization unit 1, as a result, a start command of the reading unit 18 appears on its output, in which the non-operative information from the programming console is recorded. This graphic information information is compiled in block 5 in accordance with the display of the default layout. This means that each kaschau corresponds to an array of code words, each of which is represented by a reference point of the element with frame-waving karginkn.

Then, the output of the comparison unit 19 is selected by the Komava Full String, which enters the generator 21 in accordance with the stitching of all the image elements from the gas for the double-sided panel 4, as well as the blocks 2 3, their BOTfo 6 buffer in the 7 address registers , trigger 8, According to the second komavde from the output of block 18 In the case of the register 2O, the output of the latter is zero. The third to the output of block 18 is assigned to azod t from уuferno govreg str 17 to the address register 2O of the new frame. A quarter of the Land Registry reads the instruction code from the cell of block 5 at the address, cooTBeTCTByrora kiy frame number. A high level from the output of the instruction code decoder 22 starts the interpolator 13, at the output of which a sequence of commands appears. If the comparison turns out that the codes from the outputs of the address 2O and the buffer 17 registers are equal, the frame code recorded in the address register 2O does not change, and the subroutine execution starts with the fourth command. Further, the work of the proposed device is similar to that described above. After the launch of the interpolator 13, the process of its operation proceeds similarly to the process of working with memory blocks discussed above. After that, as all the elements of the graphic information are formed, and the erased points to be renewed are recorded on the gas discharge display panel 4, the input of the synchronization unit 1 from the output of the interpolator 13 receives the command to complete the execution of both the subroutine and the time cycle Massage neither. It should be noted that, in general, the display of information about the image elements takes up a small part, as a rule, not more. 1/5 Therefore, ESPI. during the critical period of flashing of Tcr2O ms, to erase 1O ms of mobile elements and the same to record them, then the total number of highlighted points in the array of moving elements. The number of 1x illuminated points in the array of fixed elements can be a number of erased points from this array does not exceed 1-5. Resume of the erased points occurs during the time interval Ter 5 00 m s. Due to the fact that the number of erased points is small, despite the process of renewing the points, it is not visible to the operator's eye. The use of the proposed device allows several times to increase the amount of signographic mappings displayed on the gas discharge display panel by reducing the time for generating sign information by erasing and writing to the gas discharge display panel only mobile elements of the image, as well as cyclic renewal. erased points of fixed elements. And this, in turn, makes it possible to increase the speed of the display device with gas discharge display panels of alternating current,. working according to the principle of sequential recording of images and for cases when this image is composed of moving and stationary elements, which allows reducing the weight and dimensions of the entire display system, increase its reliability and thus apply the cage to small V-sized vehicles.
