SU1179418A1 - System for training telegraph operators - Google Patents

Description

The invention relates to techniques of communication, in particular to devices for controlling the degree of learning, and can be used in the process of learning to work on telegraph devices.

Under normal conditions, monitoring the observance of the rhythm when working on a telegraph apparatus is carried out by observing the supervisor of the trainee’s work, while the supervisor is in close proximity to the telegraph operator. This sometimes leads to undesirable phenomena: the student begins to get nervous and admits mistakes.

The aim of the invention is to expand the didactic capabilities of the simulator with increasing objectivity in monitoring the degree of training of the telegraph operator by analyzing the rhythm of his work and improving the effectiveness of training through the timely application of appropriate techniques aimed at eliminating the identified shortcomings.

The drawing schematically shows a telegraph trainer.

Telegraph operators' simulator contains 1 operator’s control panels, including transmitters 2 and receivers 3, switch 4, control console 5, DC amplifier 6, information transmission analysis block 7, block 8 for non-rhythmic response, driver 9 codes, decoder KU, counter 11 errors, counter 12 non-rhythmic responses, a delay element 13, an acoustic rhythm master, made in the form of a metronome 14 and a display board 15.

The switch 4 is made of switches 16 and 17, block 7 - from register 18, inverter 19, clock generator 20, recorder 21 and adder 22, and block 8 - from inverter 23, prohibition element 24 and one vibrator 25. Panel 1 and 5 , the switch 4 and the amplifier 6 form the operator response input block 26.

The simulator works as follows.

Before switching on the simulator, the shaper 9 and the one-shot 25 using switches (not shown) are set to the transmission speed at which the trainees should work at this stage of preparation.

When power is turned on, the code combinations from the output of the shaper 9 at a given speed arrive at the decoder 10 and into the recorder 21. From the output of the decoder 10, a control signal is taken, which arrives “on the display 15 and displays the symbol of the sign for visual perception by the telegraph operator. The same signal arrives at element 13, the delay time of which is equal to half the time the sign flashes. From the output of the element 13, the signal enters the metronome 14, providing a rhythmic soundtrack of the sign, and to the input of the one-shot 25. The single-vibrator 25 is started and a positive potential (pulse) with a specified duration appears on its output, which is applied to the locking input of the element 24.

The student, having perceived the displayed sign displayed on the scoreboard 15, with the rhythm set by the metronome 14, presses the key corresponding to the given sign. Transmitter

2 console 1 generates a code combination, which enters the receiver 3 and is printed on the tape in the form of a sign.

Let it be necessary to control the transfer of a student working on the second console. The head on the switch 4 presses the button 16 ("Control"), thereby connecting the console 1 to the input of the amplifier 6 and the inputs of blocks 7 and 8. The code combination from the output of the transmitter 2 of the console 1, passing through

amplifier 6, will go ’to receiver

3 remote control 5 and will provide the printing of a sign similar to that printed in the receiver 3 of the remote control 1.

The same code combination will be written in the register 18. At the end of 45

Pisy starting package with. the output of the register 18 will pass through the inverter 19 and will start the generator 20. A series of single pulses from the output of the generator 20 will go to the input of the register 18 and the input of the recorder 21, ensuring the simultaneous output of the information recorded in them to the adder 22.

When the key 55 is correctly pressed, the student (the key pressed corresponds to the character displayed on the scoreboard 15) the code combinations recorded in register 18 and the recorder 21,

will be identical, therefore, the 'output of the adder 22 signal will not.

If you press a key incorrectly (the pressed key does not match. 5

to the sign displayed on the board 15) the compared combinations will be different and a pulse will appear at the output of the adder 22, which will go to the counter 11 and detect an error. ten

The code combination from the output of the console 1 will also go to the input of the inverter 23, the starting premise of which, if there is a signal at the prohibiting input of the element 24- from the output of the one-oscillator 15, will not pass to its output, i.e. pulse in the counter 12 will not arrive.

The keystroke by the student is performed in rhythm with the metronome.

If the code combination from the output 20 of the console 1 arrives at the information input of the element 24 before the signal appears at the output of the one-vibrator 25 (at the prohibiting input of the element 24), then the starting pulse from the output 25 of the inverter 23 will pass through the element 24 into the counter 12, which will be fixed non-rhythmic response.

By the number of errors (or their absence) in the counter 11 and the number of non-rhythmic answers in the counter 12, the degree of readiness of the telegrapher is estimated.

If it is necessary to immediately eliminate the deficiencies, the manager presses the button 17 (“Warning”) in the switch 4 and, interrupting the work 18 4.

the controlled telegraph operator, gives him the appropriate instructions by stamping receiver 3 of console 1 on the telegraph tape without attracting (diverting) the attention of other trainees.

To return the counters 11 and 12 to their original state, turn off and then turn on the power.

The use of the invention in devices for monitoring the work of telegraph operators in the learning process allows to increase the objectivity of the transmission control by identifying, along with errors caused by incorrect reproduction of one or another sign, errors associated with disturbances in the transmission rhythm. Depending on the number and correlation of the recorded errors and non-rhythmic answers, the manager has the opportunity to apply this or that technique in a timely manner to quickly eliminate the deficiencies allowed by the student, which contributes to both improving the effectiveness of training and improving the quality of training. The lack of direct control (being near the telegraph operator) at the student’s work allows the latter to work out the exercises in. optimal conditions (lack of stimulus) and fully manifest its capabilities. All this leads to a reduction in time for the preparation of telegraph operators, especially in the initial period of study.
