A comparator 17, a block of 19 keys, a delay element 15 and the elements OR 18 and 20 are introduced into the device. Random number generator 1 is made in the form of a generator of uniformly distributed pseudo-random numbers. The simulator also contains a block 2 tasks for the training program, a switch 3, an encoder 4, a block 5 for controlling the speed of presenting information, shapers 6 and 8 codes, blocks 7 and 9 for presenting educational information, block 10 for comparison, blocks 11 and 13 for entering Responses, a generator 12 pulses, shaper 14 Morse codes. 1 il. i (o

Description

The invention relates to technical training aids and can be used in equipping specialized training rooms for the training of hearing aid operators.

The purpose of the invention is to expand the didactic capabilities of the simulator while reducing the training time of operators and improving its quality.

The drawing shows a structural diagram of the proposed simulator.

The simulator contains a generator of 1 random sequence of codes, block 2 of the task of the training program, switch 3, encoder 4, block 5 of controlling the speed of presenting information, shaper 6 of codes, block 7 of presenting educational information, shaper 8 of codes, block 9 of presenting educational information, a comparison unit 10, a response input unit 11, a pulse generator 12, a response input unit 13, a Morse code generator 14, a delay element 15, a memory block 16, a comparator 17, an OR element 18, a key block 19, an OR element 20.

The simulator works as follows.

When the simulator is turned on, the generator 1 generates a uniformly distributed random number, and in block 16, the address of the address is set to zero, the initial state after switching on. The operator enters the simulator through block 11 (in the Transmission mode) or through block 13 (in the Receive mode) pseudo-response corresponding to an arbitrary pilot signal, which respectively through the generator 12 or through the driver 14 enters the block 10.

If the signals from the output of the positive signals P of the block 10 coincide, the pulse arrives at the inputs of the block 5, the generator 1, the block 16 and the element 18, which corresponds to the correct response of the operator, causing the corresponding operation of the simulator circuits.

In case of a mismatch of the signals from the output of the negative results O of the block 10, the pulse arrives at the input of the element 18, from the output of which the pulse arrives at the input of the element 15 and at the input of the block 16, reading

information on the current address of the address.

After the time determined by the reading cycle from block 16, the information read at the current address is set at its output, and then the element 15 enters the synchronization bus of the comparator 17 from

the form of a pulse synchronization signal.

The synchronization signal in comparator 17 compares the numbers from generator 1 (number A) and from block 16 (number B).

If the signal from the second or third output of the comparator through element 20 opens the keys of block 19, and the current reading address from the output of block 16 enters the input of block 2, specifying the number of the training program to present the next pilot symbol to the operator and cause the corresponding output signals on block 2.

If, the signal of the comparison result from the output of the comparator 17 is fed simultaneously to the input of the element 18 and to the input of the block 16, causing the current reading address to increase by 1. Then the signal from the output of the element 18

arrives simultaneously to the input of the element 15 and to the input of the block 16, carrying out the operation of reading the word at the current address and setting the number B at the input of the comparator. After that, from the output of the element 15 to the sync bus of the comparator 17 the synchronization signal again comes, causing another comparison of the numbers A and B.

The processes of successive escalation of the address are determined by the reading and maturing of the contents of the cells of block 16 (the number B) with the number from generator 1

(number A) are carried out until a ratio is reached, which results in the appearance of corresponding signals at the output of block 2.

The output signals of block 2, which are the code designation of the letters or numbers found in the reference text, are sent to the encoder 4, where they are converted into Morse code signals and

through the contact group of the switch 3 (transmission and reception) are fed to the formers 6 or 8. Simultaneously from the output of the encoder 4, the signals arrive at the input of the block 10.

In the 3 mode, the transfer of the sign of the Morse code through the contact group of the transfer switch is sent to the driver 6 (for example, a diode decoder), which along control circuits causes the display of information on the display unit 7 (for example, a tablet from a set of LEDs) in the form of letters or numbers. The reference signals from the encoder 4 are compared with the signals of generator 12, which are generated in accordance with the operator's actions using block 11 (for example, a telegraph key) when transmitting the presented letters (numbers) by Morse code.

If the signals do not match, the highlighted information on the display of block 7

does not change, since from the output of negative results, element 18 sends a signal to re-read the word from block 16 at the current address, and since the values of the current address and the random number generated by generator 1 did not change, the ratio and as a result of the processes considered for this relation in the circuit, that

25 to the ratio of the AB, which leads, as a result of the considered, to the design of the device scheme to the emergence of a new Morse code signal in the headsets of block 9. In addition, with the correct

30 operator's actions in the reception mode, unit 10 acts on unit 5, which, depending on the set number of correct results

same current address, repeat the same training program number.

When the signals from the output of the positive results of the 10 P block coincide, a pulse arrives at the inputs of block 5, generator 1, at the input of block 16 and at the input of element 18. In this generation, the rator 1 generates a new random number A, and the address of the block 16 is The positive effect, which is expressed by tanning, is then read out from block 16 by the signal from the output of element 18, number B, after which it produces -40 is fired by the fact that, when set on the sync pulse from the output of the element, in the comparator 1 7 comparison of numbers with When training A and B, the operator drove a further sampling of numbers from the block to process less than 16 to satisfy the ratio, the mental signals (points, dashes), and at which the pulse from the second or 45, due to unequal, from the third output of the comparator 17 through these frequencies, the occurrence of the symbol 20 opens block 19 to transmit to the input of block 2 the current read address corresponding to the number

in reducing the time of training of operators and its quality, the symbol of the control signal.

This sets the next training program number and causes the issuance of 4 new Morse code signals via the encoder, which in turn leads to a change in the information on the display unit 7.

In the Reception mode, the operator according to the rhythmic pattern (melody) of the prefetch in the control signal, the more frequently encountered characters are mastered by the operator relatively better, as a result of which less errors occur in practical work. In addition, a reduction in the total number of elementary symbols of a control signal of a given length due to less operator fatigue 55 leads to an improved perception quality and memorization of educational information contained in the control signal and to a more high-quality working out of the corresponding skills of operators.

through the headphones of block 9, it determines the letter (number) and by means of block 13 (for example, a set of toggle switches, a keyboard block) fixes its reception. In this case, the driver 14 generates an appropriate structure of electrical pulses, which are compared to the reference signals in block 10 through the contact group of the switch. If the signals from the output of the negative results do not match, the signal from the block 10 receives the input of the element 18, which leads to the repeated selection of the program of the block 2 and to repeat the Morse code signal in the headphones of block 5.

With the coincidence of the signals from the output of the positive results of the P block

10 a pulse arrives, providing the next start of generator 1, sampling from block 16 the numbers written in it and comparing them with random number of generator 1 to satisfying the AbB ratio, which results in the result of the considered triggering device circuit to the appearance of a new Morse code signal in headphones block 9. In addition, with the correct

operator’s actions in the reception mode, unit 10 acts on unit 5, which, depending on the number of correct results

information, a positive effect that is expressed is caused by the fact that with a given signal, in symbols, the length of the control signal, the operator must rework less elementary signals (dots, dashes), and due to uneven, with prescribed frequencies, symbolic
