The invention relates to the field of automation and computer engineering, in particular, to devices for displaying information on the screen of a cathode ray tube and can be used to quickly provide information on the progress of technological processes and issue commands to the control object.

The purpose of the invention is to expand the scope of the device due to the ability to flicker the necessary control objects and generate commands for changing the process flow.

The first interface unit 8 (Fig. 2) comprises a register 12, reversible counters 13 and 14, a memory unit 15, a register 16, pulse shapers 17 and 18, a register 19.

The control unit 1 (Fig. 3) comprises a clock generator 20, address counters 21 and 22.

The device operates as follows,

The device has four operating modes. In the first mode, the image is formed, the second is the search for an object, the third is the formation of a control command, and the fourth is the object control mode.

When forming the image, the boot mode of the computer device is executed. In this case, the address / data signals 34 (Fig. 6) are generated in the computer channel. The address selector 29 decrypts the addresses 35 (Fig. 6) exposed on the computer channel. At

5, coincidence of the set address with the device address, address selector 29, upon receipt of data in the computer channel by the signal 34 (Fig. 6), switches the transceiver 31 to receive signals from the channel in the device 36.

0 Thus, data is entered into the device. When data is received on the computer channel, the receiver 31 is transferred to the third state. If necessary, the cycle is repeated. Address for device operation

5 is held by register 19, the control signal of which is received from address selector 29. Addresses recorded in register 19 are addresses for memory unit 15. The write signals to memory blocks 15 and 4 are shown in FIG. 6, pos. 37.38. Depending on the address signals at the outputs of the memory unit 15, control signals for the operation of the register 12, the reversible counters 13 and 14, the memory unit 4, the switch 7 and

5 comparators 10.

When a key is pressed on the keyboard 10, a signal Inf / control 1 is generated depending on whether the key belongs to information or control groups. AT

In the imaging mode from the external bus, the first inputs of the reversible counters-13 and 14 of the interface unit 5 receive the coordinate codes X, Y, and the inputs of the data code register 12. From register exit

5-12, data codes arrive at the inputs of memory unit 4, and addresses to memory unit 4 come through switch 7 from the outputs of interface unit 5. Addresses during image formation are supplied from the outputs of the counters

0 13 and 14. From the outputs of the switch 7, the familiarity addresses go to the inputs of the memory unit 4. Each familiarity on the CRT screen corresponds to a memory cell in memory unit 4. In the memory cells of the memory unit 4, the type of symbol, its color, background color, and scale are programmed. A symbol type code is used to read information from a 2 symbol generator. In this case, the symbol code is supplied to the inputs of the 2 symbol generator, and the color code of the outputs of the memory unit 4 is supplied to the inputs

shaper 3 video signals. According to the video signal coming from the 2-character generator and the color code, the video driver 3 generates three color signals (red, green, and blue). Simultaneously with the imaging of the process, a marker is formed on the screen of the device. A marker is needed for the user to search for the desired object in the mnemonic diagram. The marker mark is generated by the comparator 9. When comparing the addresses coming from the outputs of the control unit 1 and the addresses from the counters 13 and 14, a signal (marker mark) is generated at the output of the comparator 9, which is fed to the input of the video signal generator 3 and the input of the register 11. Thus The CRT screen displays a process flow chart and a marker. The latter may be located anywhere on the screen.

In object search mode, the user is faced with the task of combining the marker with the desired object. In this case, pulses are supplied from the keyboard 10, counters 13 and 14 to control the marker. The pulses on the registers are fed to the inputs ± 1. Thus, the addresses at the outputs of the counters 13 and 14 can be changed if desired by the operator using the keypad 10. The result of changing the addresses is to change the position of the marker on the image. By pressing the f, 1 - - keys on the keyboard one by one, you can combine the marker with any object on the mnemonic diagram. After aligning the marker with the object, the latter begins to flicker. In this case, the flicker control signal is supplied from the output of the comparator 8 to the input of the video shaper 3. At the inputs of the comparator 8, the object code is received from the outputs of the memory unit 4 and the register 11. After the object is selected from the keyboard 10, the interface code 16 receives the command code and the signal Info pos. 42 (Fig. 6) is written to it from the keyboard. At the same time, the signal Inf is used to generate the received signal by the driver 18. This signal is output from the interface unit 5 to the keyboard input. When the control signal (key 42, FIG. 6) is supplied from the keyboard to the former 17, the signal Interrupt pos. 43 (Fig. 6), which shuts down the computer to receive the corresponding command. In this case, the computer codes through the transceivers 32 and 33 come from register 18, and the object codes from register 11.

In the object control mode, a control command is generated by means of information and control codes coming from the keyboard 10. 5 In this case, an control sequence of codes is received from the outputs of the register 16 of the interface unit 5 to the input bus, and the object code is sent from the output of the register 11 . The computer checks whether the control

0 object code of the object, if so, then identifies this code and performs the specified control of this object.

The control unit generates control pulses for the symbol generator, video signal conditioner, as well as address signals for the operation of the switch 7 and the comparator 9. The clock generator 20 generates clock pulses, which are then transmitted to the address counter 21,

0 from the output of which the address signals through the switch 7 are fed to the address inputs of the memory unit 4 and directly to the comparator 9. From the output of the counter 22 addresses the address signals also come through

5 switch 7 to the address inputs of the memory unit 4 and other inputs of the comparator 9. To control the 2-character generator, control signals are received from the control unit 1 from the outputs of the counters 21 and 22

0 addresses.

Shaper 3 video signal operates as follows. The input signals from the generator of 2 characters receive the video signals of the characters, and at

5, the inputs of the registers 25 and 27 and the input of the divider 28 from the control unit 1 receive write pulses. Divider 28 determines the flicker period. From the output of register 25, color codes are fed to the information inputs of switch 26, which is switched by a signal from the output of register 27. At three outputs of switch 26, color signals R, G, B appear, which are fed to the inputs of video control device 5. The color codes of symbols and gender are received at the first inputs from the outputs of memory unit 4, and the video signal of the marker is generated by comparator 9. The flicker control signal to memory unit 24

0 comes from the output of the comparator 8 through the element 23 AND NOT. The memory unit 24 is a read only memory that is pre-programmed. It calculates the color of the marker,

5 contrasting color of the floor and the symbol. The calculation is carried out according to the rules, which are described by the expressions

PR SZ + SK + SS + FZ t FC + FS (1)

where PR is the priority of the marker;

SZ, SK, SS - color codes of the characters, respectively, green, red and blue;

ФЗ, ФК, ФС - background color codes for green, red, and blue, respectively;

M - marker signal;

T-flicker;

VFK, VSK, VFZ, VSZ, VFS, VSS - output codes at the outputs of block 24 of the memory.

In the device, control is also carried out by the operator, however, the action of the operator is reduced only to aligning the cursor with the control object. In this case, after fixing the object using the keyboard, a control command is issued to the object (see, a block diagram of the algorithm of the device in Fig. 7). A complete image consists of several objects and the formation of individual objects (see Fig. 8) is carried out by means of its description (see table). The description of the object contains familiarity addresses, and a code is assigned to the latter to recognize the object itself. In addition, the description contains the character codes of which the object is composed, character color, background color, and flicker.

Thus, the expansion of the scope is achieved due to the ability to control the technological object by issuing commands to the computer and the control object.
