A simulator 2 is known, comprising a transmitter, a decoder, an analyzer, a reversible counter, an additional decoder, a control unit, a light board, a work result accounting unit and a response device. It allows the trainee to use the hint if necessary.

However, this device does not allow evaluating the work of radio telegraphists in extremal conditions, which reduces the effectiveness of training.

The purpose of the invention is to improve the training of radio telegraphists by assessing the quality of the operator’s work under extreme conditions and ensuring control of his emotional stability.

This goal is achieved by the fact that a simulator containing sequentially connected random driver, block of input for training program, encoder, block of memory, driver of control pulses, pulse builder of Morse code, control block of information input,.

The trainee is presented with a random sequence of Morse code characters. In the process of learning, resistance is continuously monitored, the magnitude of which evaluates the emotional intensity of the operator, which allows for the timely registration of a state deviation from the norm. The OneppiTop processes the sign sequence and, assuming an error, is exposed to a short-term current of a certain magnitude.

FIG. 1 shows the block diagram of the proposed simulator; in fig. 2 and 3 are diagrams of blocks of adaptive control and evaluation of the emotional intensity of an operator.

The simulator contains serially connected shaper 1 random signals, block 2 of the training program input, encoder 3, block 4 of memory, shaper 5 of control pulses, shaper 6 of Morse code pulses, block 7 of comparison, block 8 of input of operator response actions, block

9 input control block

10, an adaptive control unit 11, an operator's electric conductance meter 12, an operator response input unit 13, an operator's emotional stress assessment unit 14, and a registration unit 15.

Block 14 contains an amplifier 16, the input of which is the input of block 14, and the output is connected to block 15 and to the inputs of amplitude selectors 1.7, 18, 19, the outputs of which are connected respectively to the single inputs of a group of flip-flops 20, 21, 22, the outputs of which are the output of the block 14 connected to the block 11, and the output of the trigger 22 is connected to one input of the element OR 23, the other input of which is connected to the output of the trigger 20, and the output connected to the zero input of the trigger 21, the output of which is connected to the zero inputs of the trigger 20 and 22 .

Unit 11 contains a series-connected current source 24, a (controlled) current divider 25, a key 26, the output of which is connected to one input of the element OR 27, a costopioro output is the first output of the unit 11, to another input which is connected in series with a key 28 and (unmanaged) current divider 29, whose input is connected to the output of source 24, trigger 30, whose single input is the input of block 11, and the single output, which is the second output of block 11, is connected to the control input of the key 26 and triggers input relay 31

time, the output of which is connected to the zero input of the trigger 30, the zero output of which is connected to the control input of the switch 28, and the inputs of the current divider 25 connect the block 11 with the block 14.

The device works as follows.

With the help of shaper 1, block 2 (representing, for example, an annular shift register for n numbers and a matrix for n horizontal and m vertical tires, and both the connection and the disconnection of any ni horizontal tires with any t-vertical bus is provided by a punched card, embedded in the matrix) and the encoder 3, the characters are formed and translated into Morse code, and then they are recorded in block 4.

Block 4 permanently holds a series of 1 characters that are used to train the wireless telegraph operator. From block 4, each sign of the sequence through the imaging unit 5 enters the imaging unit 6 and headphones (not shown in the diagram). In this case, block 9 locks block 8 during operation of shaper 6. After block 4 issues the entire sequence of characters, block 9 opens block 8 and simultaneously the first character of the sequence from block 4 goes through shaper 5 to block 7. The second input of block 7 receives a signal from the block 8, with which the learner forms the answer.

The signal in the student's correct response is fed to the shaper 5, which performs the output from block 4 following the sign de to the input of block 7, and is fixed by block 10.

If the student correctly processes the entire sequence of characters, the shaper 5 sends the command to block 4 to erase this series and record a new series of characters.

If the student makes a mistake, then block 7 generates an error signal which is fixed by block 10 and fed to the imaging unit 5 and to the output of block 11. In this case, a series of characters will be issued again sequentially, and the device operation cycle at the same time, when an error signal appears, from the output of the block 11 to the meter 12, the signal is fed, which disconnects the measuring circuits of the meter 12 -k to the contact sensors of the block 13 is briefly applied to the current of a given magnitude. In this case, the pain creates. Extreme conditions of training as a telegraphist, causing a change in the success of his training.

In those cases when the learner responds correctly block 11 through

The circuit of the meter 12 to the contact sensors of the unit 13 delivers a weak current.

In this case, from the output of the meter 12, a signal is taken proportional to the electric resistance, the value of which, using block 14, determines the degree of change in the functional status of the radio telegrapher and corrects the magnitude of the exposure current.

In the schemes of blocks 11 and 14, the following occurs. In those cases when the learner does not make mistakes, the trigger 30 of the block 11 is in the zero state, in which the key 28 is opened and a low value current is supplied to the measuring circuits of the meter 12 through the OR 27 element, the specific value of which is determined by the unregulated current divider 29 included between source 24 and key 28.

The signal from the output of the meter 12 is fed to the input of the amplifier 16 of the block 14 and from its output to the block 15 and to the outputs of the amplitude selectors 17, 18 and 19, by means of which three sections of the conductivity change are identified. The appearance of a signal at the input of one of the selectors triggers the trigger connected to it and keeps it in such a state, while the conductivity value is within intervals determined by the given g1 amplitude selector. Triggering one trigger puts the triggers in the zero state.

Block 14 makes it possible to obtain three estimates of emotional intensity and, in accordance with them, controls the factor 1; the divider 25 of block 11, thereby correcting the magnitude of the effect current. When an error signal appears at the output of the block 7. The trigger 30 of the block 11 is transferred to one state, in which the signal from its single output turns on the measuring circuits of the meter 12 from the sensor of the block 13, opens the key 26, turns on the relay 31 and contacts the sensors of the block 13 a short-term (duration of time relay parameter determination) current is applied, the value of which is determined by the state of the controlled divider 25. After a predetermined time, the signal from the output of the relay 31 puts the trigger 30 into the zero state, returning block 11 to its original position and connect the measuring circuit of the meter 12 to the contact sensors of the block 13.

The value of the emotional focus and evaluation of the actions of the radio telegraph operator is recorded in block 15.
