Description

The invention relates to automation and computing, in particular to devices for training and control, and can be used for training work on 5 telegraph devices.

The aim of the invention is to expand the didactic capabilities of the simulator by determining the cause of errors (incorrectly pressed key, about Vichy sign).

The drawing shows a diagram of the simulator telegraph operators.

The telegraph simulator contains the operator’s console 1, made in the form of, 5 telegraph apparatus with transmitter 2 | and receiver 3, register 4, analysis block 5, the first input of which is combined with the first input of register 4 and connected to the output of the transmitter 2, generator 20 6 clock pulses, the output of which is connected, to the clock input of register 4, and input to the output of block 5 analysis, shaper 7 codes, the output of which is connected to 25

the input of block 5 and through the decoder 8 to the display block 9, and the input to the output of the element 10, the inputs of which are connected to the outputs of the analysis block 5, the outputs of which are connected to the error counter 11, through the decoder 12 to the display block 13 and to the input of the receiver 3 .

Block 5 analysis contains the register 14, '· inverter 15, the generator 16, the counter 17, the delay element 18 ,, the element BAN

19, the trigger 20, the keys 21 and 22, the recorder 23, the adder 24 modulo two, the inverter 25 and the element And 26.

The simulator works as follows - * θ at a time.

about

When the simulator is turned on, shaper 7 generates a code combination that arrives at the decoder 8 and 45 registrar 23. When a code combination arrives at the decoder 8, a control signal is taken from its output, which displays the symbol for visual perception by the telegrapher . Simultaneously, the zero potential from the output of the adder 24 is fed to the trigger input

20, ensuring the presence at its output of a single potential, which ‘55 is applied to the control input of the key 22, and to the input of the BAN item

19, preventing false alarms

trigger 20 by keystroke. The simulator is ready to go.

The telegraph operator, having perceived the displayed sign displayed on the display of the display unit 9, presses the key corresponding to it. From the output of transmitter 2, the code combination is generated in accordance with the key pressed and enters registers 4 and 14.

At the end of the recording of the code combination from the last digit of the register 14, the starting parcel arrives, which, transforming at the output of the inverter 15 into a single potential, starts the generator 16. A series of single pulses fed into the register 14 and into the recorder 23 from the generator 16 ensures the output of the recorded information from them to the adder 24. The same series of pulses, received in the counter, 17, is delayed by element 18 for the duration of the comparison. After issuing a series of pulses, the generator 16 is turned off.

If the key is correctly pressed by the telegraph operator, the compared combinations will be identical, the zero potential at the output of the adder 24 will not change. The pulse from the output of element 18 will turn off the generator 6, ensuring reading of information (reproduced sign) from register 4 through the public key 22 and printing the mark on the receiver 3. This same pulse from the output of element 18, acting on element 26, will pass through element 10 on the driver 7 and will provide a flashing of the next sign - on the scoreboard of block 9.,

If you press the key incorrectly, the compared combinations will be different and a single potential will appear at the output of the adder 24, which, acting through the inverter 25 on the element 10, will prevent the next character from the output of the driver 7, will flow into the counter 11 and fix the error, and also trigger the trigger 20 to the position in which a single potential appears at its output acting on the control input of the key 21. The pulse from the output of the element 18 will turn on the generator 6 and will provide the reading of erroneous information from the register 4 through the key 21 decoder 12, On the display panel of block 13, the sign incorrectly transmitted by the telegrapher will be displayed.

When the key is correctly pressed, the impulse from the output of element 18 goes through the information input of element 19 (since its potential input has zero potential) to the input of trigger 20, ensuring the appearance of a single potential at its output; if the key is incorrectly pressed, the pulse from the output of element 18 does not pass through element 19 (since there is a unit potential at its inhibiting input), and a pulse from the output of adder 24 is applied to the input of trigger 20, which ensures the appearance of a single potential at its output.

The student, having seen the sign passed by him on the scoreboard of block 13, immediately

determines the cause of its occurrence. and corrects the error.

The use of the invention and devices for training telegraphic top in the transmission on the telegraph apparatus allows you to expand the didactic possibilities by identifying the causes of mistakes due to improper keystrokes. Knowledge

10 the trainee and the leader of the causes of errors makes it possible to quickly eliminate them by applying appropriate methodological techniques. This provides increased efficiency.

15 of the process of training telegraph operators and reducing the time allotted for mastering the keyboard of the telegraph apparatus.
