The invention lends itself to technical learning tools and can be used to prepare students to work on telegraph devices.

The aim of the invention is to expand the didactic capabilities of the simulator.

FIG. 1 shows a functional diagram of the simulator; in fig. 2 - time diagrams that show his work.

The telegraph operator's simulator contains a register 1, a sensor 2 codes, a block 3 registers, a display 4, a block 5 of control, a block 6 of synchronization, an adder 7 modulo two, a single vibrator 8, an electroacoustic converter 9, the first counter 10 errors, the first delay element 11. The input of the device is connected to the output of a telegraph apparatus 12 consisting of a transmitter 13 and a receiver 14.

Block 3 of registers contains registers 15i-15 „(n is the number of characters in a line).

Table 4 contains decoders 1b | -16 „and cells 7 | -17 „displaying line characters.

The control unit 5 comprises an inverter 18, first and second 19 and 20 triggers, a pulse shaper 21 and a delay element 22.

Unit 6 contains a pulse generator 23, the second counter 24, the second and third 25 and 26 delay elements.

The simulator works as follows.

Include food. The triggers 19 and 20 are set to the zero state (Fig. 2 a, b). The shaper 21 starts up, a short pulse (Fig. 2c) from the output of which is fed to the input of the sensor 2 codes, ensuring the formation of the code combination that enters the information inputs of the register 15, at its group output. At the same time a short pulse from the output of the imaging unit 21 is fed to the input element II. The delayed pulse from the first output of the element 11 is fed to the input of the register mode 15, switching it to parallel recording mode, and then, having arrived at the second output of the element 11, enters the input of the register 15, recording, ensuring parallel recording of the binary combination of the sign from the output sensor 2 to register 15. A binary code combination from the outputs of register 16 "(Fig: 2 g) is fed to the information inputs of the decoder 16", from the outputs of which the signals are fed to the inputs of cell 17 "board 4.

The pulse from the output of the imaging unit 21, received at the input of the element 22, the delay time of which is longer than the delay time of the element 11, enters the S-input of the trigger 20 and sets it to unity. A single potential from the output of the trigger 20 (Fig. 2 b), filed at the input of the illumination of the cells 17, provides the flashing of the sign on the board 4.

Keystrokes (the number of keystrokes depends on the length of the line, with a length of six characters, five keystrokes), the line (cells 17 of the board 4) is filled with characters.

Upon hitting the key, the code combination of the character from the output of the transmitter 13 of the telegraph unit 12 is fed to the input of the receiver 14, imprinting a sign on the tape, to the first information input of the register 1

and to the input of the inverter 18 (Fig. 2 d). The first starter sending of the code combination, acting through the inverter 18 to the R input of the trigger 20, resets it (Fig. 26), removes a single potential from the inputs of the cells 17, and

5, applied to the S-input of the 19F trigger, will cause the appearance of a single potential at its direct output (Fig. 2a). This potential is applied to the input of generator 23 and starts it. Clock pulses from the output of the generator 23, delayed by the element 25 at the time,

0 is slightly less than t (t is the duration of the elementary parcel), register 1 is sent to the shift input (Fig. 2e), providing a record of the binary combination (without the starting sequence) to the last one.

5 The delay of the element 25 is chosen so that when the sixth clock pulse appears at its output (the seventh pulse at the output of the generator 23), a pulse appears at the first output of the counter 24 (Fig. 2 g). Clock pulses from the output

0 element 25 and the first output of the counter 24 are received respectively on the shift inputs of registers 1 and 15, ensuring the simultaneous extension of information from their outputs. In this case, information from registers 1 and 15i is read into adder 7, and from registers

5 152-15 „respectively in registers 15i - 15. I.

Upon receipt of the eleventh clock pulse from the output of the generator 23 into the counter 24 (the tenth pulse appears at the output of the element 25), a second pulse appears at the second output of the counter 24 and a delayed element 26 1/2 The t (Fig. 2i) will go to the R input of the trigger 19, ensuring the appearance at the direct output of zero potential (Fig. 2a), which includes the generator 23.

Since the readout information from registers 1 and 15i to adder 7 is different, then at the output of adder 7 a pulse appears that triggers the one-shot 8 (Fig. 2 / s). Single potential output single

0 novibrator 8 enters the counter 10, fixing the recording of the mark in a row, and to the input of the electro-acoustic transducer 9, notifying the recording of the mark with a sound signal. The change in the single potential at the second output of the trigger 19 causes a short pulse at the output of the former 21 (FIG. 2 b), which ensures the formation and writing to the register 15 of the following code combination from the output

sensor codes 2, as well as displaying information on the board 4.

The teacher (the student) presses the keys again, writing down the next character on the line as described above. After recording the mark in the cell 17 | presses the button "Reset (not shown), returning to the initial state the counter 10.

On board 4, a string of characters is displayed for visual perception by the student. The simulator is prepared for work to perform a telegraph training session.

The student, remembering the characters in the line highlighted on the scoreboard 4, presses the key corresponding to the first character of the line. From the transmitter output 13, the code combination enters the simulator input. The work of the blocks and elements of the simulator during the training of the student is carried out similarly to the input of characters during the initial recording of the string.

At the same time, the student immediately after voiding the first character orients the fingers of the corresponding hand on pressing the clavine and the next character in the line, which is displayed after the passage of the first character, i.e., the character moves along the line. The last character in the string is new.

If a sound signal occurs after a key is pressed, this means that the student made a mistake, which is recorded in the counter 10. The incorrectly reproduced character is recorded on the tape of the receiver 14.

The simulator allows you to increase the effectiveness of the training and increase the build-up of the speed of wiring by ensuring the timely coordination of the actions of the fingers.
