Description

The invention relates to technical training equipment and can be used to equip specialized training rooms for the training and professional selection of hearing aid operators.

A simulator is known that is designed to teach skills and control the reliability of radio signals from a radio telegraph operator and contains a memory block whose input is connected to the Task panel and the output to the comparison unit, another input connected to the keyboard unit, the output of the comparison unit is connected to the unit of the accounting of the results of work, connected, in turn, with the sound signal sensor of the Morse code 1.

However, the simulator has a rigid program of limited length, which leads to a low efficiency of the learning process due to repeated processing of the same program.

However, this simulator is characterized by low efficiency due to the fact

5 that allow unlimited time

0 the rate of the wireless telegraph operator, which in turn leads to an increase in learning time.

The wireless telegraph simulator contains the generator 1 (random numbers), block 2 of the training program, block 3 of memory, encoder k, block 5 of the speed control for presenting (training) information, code generator 6 Additional block 7 of the presentation of educational information, figure 8 codes, block 9 of presentation of educational information, block 10 of comparison, block 11 of entering answers, generator 12 (pulses), block 13 of entering answers-, shaper 14 Morse code, group of contacts switch-tel 15 block 16 setting time, counter 17, information scoreboard 18, element And And 19, a key 20, 21 recurrently line, wireless operator switch 22. The simulator operates as follows. When the simulator is turned on, generator 1 randomly generates an integer number from 1 to k3, which is the program number for block 2. Simultaneously, the recording of this random number in block 3 occurs. The output signals of block 2 are code letters or digits are sent to encoder A, where the Morse code and Liepe3 signals are converted into a group of contacts of the switch 15 transmit-receive either to the driver 6 or to the driver B. At the same time, from the output of the encoder, the signals of the Morse code arrive at the first input of the block 10 s avneni. In the Transmission mode, the Morse code signals through another contact group of the switch 15 receive and transmit are sent to the driver 6 (for example, a diode decoder), which, through control circuits, causes information to be displayed on the unit's display. 7 (for example, a tablet and LEDs in the form of letters or numbers. The signal from the encoder 4 is compared in block 10 with generator 12 signals, which are generated in accordance with the operator's actions using block 11 (for example, a telegraph key) when transmitting the displayed letters (digits). If the signals do not match, the displayed information on the display of block 7 does not change, since the command 10 does not receive a command to start the generator 1. If the signals from the output of positive results coincide, unit 10 gives a command to the next starting the generator 1, which gives a new random number, which leads to a change in the program number of block 2 and causes the k encoder to issue new Morse code signals, which in turn leads to a change in the information on the display of block 7. In the Receive mode, the Morse code signals through the group co.nt acts of the switch 15 are fed to the imaging unit 8, block 1b (for example, a clock generator) and counter 17 (for example, see figure 2, a recurrent line 21 with two outputs, one output is fixed and connected to the display 18 with the word Error , another output is selected by The driver by switch 22 depends on the degree of readiness of the rad-1 telegraph operator and connects to the scoreboard with the inscription Faster. With the arrival of Morse code signals, a signal, for example, a unit is recorded in the recurrent line 21, and unit 16 is started and advances this command | ) along the recurrent line 21. (In FIG. 2 circuits of clock pulses are not shown). According to the rhythmic pattern (melody) of the presented signal, the wireless telegraphist through the headphones of block 9 determines the letter (number) and by means of block 13 fixes its reception. The radiotelegraphist spends a new time on deciphering (identifying) the melody, selecting and pressing the corresponding key of block 13, the beginning is recorded by writing the signal to counter 17, and the end is reading the signal. The signal from the counter 17 is simultaneously counted and reset, as well as the block 16 is stopped under the counter and information board, the first driver 14 when the key of block 13 is pressed (the erase chains are not shown in Fig. 2). The signal, advancing along the recurrent line 21 of the counter 17, first arrives at the display 18 and prepares the power supply circuit, the display with the inscription Error. If the time for identifying, searching for the corresponding key and fixing the sign is longer than the allowable one, determined by the position of the switch 22 of the counter 17, then the sial prepares the power supply circuit 18 with the inscription Faster simultaneously prohibits the output / positive results from the key 20 of the comparison block 10. When training a radio telegraph operator in the Reception mode, four cases can occur: the answer is correct, the sign fixing time does not exceed the specified time; the answer is wrong, the time of fixation of the mark does not exceed the specified time; the answer is correct, the commit time exceeds for the given time; wrong answer, commit time exceeds specified time. In the first case (when the signals coincide and the sign is fixed within the allowable time), the generated electric pulses by the shaper 14 and fed through the first contact group of the switch 15 are compared with the reference signals in the comparison unit 10. From the output of the positive results P of unit 10, the command is issued to launch another Generator 1, which will lead to the appearance of a Morse code in the headsets of block 9. In addition, with the correct actions of the wireless telegraph operator, unit 10 acts on block 5, which, depending on the set the number of correct results changes the rate at which information is presented. Table 18 in this case does not light up. In the second case (if the signals do not match and the sign is fixed within the allowable time) from the output of negative results. On unit 10, an element 19 receives a signal that lights up the display 18 with the error saying that the telegraph operator is admitted mistake. At the same time, the signal from the comparison unit 10 is fed to the start of memory block 3, through which the Morse code signal is re-presented in the head phones of block 9. In the third case (the answer is correct, but the sign lasts more than the allowed time) the signal from counter 17 through switch 22 gives a ban on key 20 and blocks the output of positive results from unit 10 of the comparison unit; through element 19 turns on unit 3 for repeating the Morse code signal and prepares the power supply circuit board 18 with the inscription Faster When the sign is fixed, electrical impulses s from shaper 14 receives the score board 18, and light with nadP1 1syu faster. This banner tells the wireless telegraphist that it does not fit into the standard time and should work faster. In the fourth case (the answer is erroneous and the time exceeds the standard} the simulator works in the same way, the error will be lit on the scoreboard 18 and the Morse code will be repeated to the teletelegraphist more quickly. The proposed simulator allows you to expand the didactic capabilities and increase the effectiveness of training. Training experience The operators of the auditory radio communication of the experimental group have shown that the time required for the development of high-speed skills can be reduced by 3040.
