Description

The invention relates to automation and computer engineering, in particular to technical training aids, and can be used in setting up specialized classrooms for the training of wireless telegraphists.

The purpose of the invention is to expand the didactic capabilities of the simulator.

The drawing shows the structure of the proposed simulator.

The simulator contains a shaper 1 random sequence of codes, block 2 of the training program, encoder 3, switch 4, shaper 5 commands, block b of training information, memory block 7, block 8 input answers, shaper 9 commands, block 10 comparison, element OR 11, clock generator 12, elements AND 13 and 14, drives of correct 15 and erroneous 16 answers, memory block 17, clock generator 18, comparison block 19, element OR 20, timer 21, key 22, decoder 23, error counters 24 , elements And 25, shaper 26 teams, information board 2 7

The wireless telegraph simulator works as follows.

When the simulator is turned on, shaper 1 generates a random integer number ranging from 1 to 43, which is the program number for block 2.

The output signals of block 2, which are the code designation of letters or numbers, through the encoder 3, where they are converted into Morse code signals in the form of current and current, and switch 4 are fed to the driver 5 and in block 7 of memory.

Shaper 5, for example, a sound generator, converts the electrical pulses of current and current parcels into pulses of sound frequency. The latter through block 6 are presented in the form of long and short sound signals to the student. At the same time, the last impulse from the driver 5 starts the timer 21.

According to the rhythmic pattern (melody) of the presented signal (sign), the radio telegraphist determines the letter (number) and by means of block 8 fixes its reception. Simultaneously with fixing the received character, block 8 generates a signal for stopping timer 21 to read the reference signal from block 7 to block 10 (the sign is read but not erased). The other input of the block 10 receives the signal shaper 9, which produces a corresponding structure of electrical pulses under the action of block 8.

The following cases are possible: the answer is correct and the time spent thinking and entering the answer does not exceed the specified one; the answer is correct, but the time standard is not met; the answer is wrong but

time standard is met; The answer is not correct and the time standard is not fulfilled.

The time standard is set by the instructor on timer 21. Last,

counting a certain time, gives a signal to close the key 22 and prepare the circuit through the element 13.

In the first case, the result of the comparison with the output of "Correctly block 10 through open. key 22 is supplied to the element 14 and through the element 11 to the generator 12.

The latter starts its operation and, under the action of its pulses, reads the information from block 7 to elements 13 and 14. Because of them, the circuit of element 14 is prepared, the information through it is written only to accumulator 15. The last pulse of the readable character from the block 7, generator 12 stops. In the second case, the simulator operates in the same way, but timer 21 generates a control signal, which closes key 22, starts generator 12 and prepares the recording circuit of drive 16 by means of element 13.

When an information generator 12 is triggered from block 7, element 13 is recorded in drive 16.

The simulator for the third and fourth cases works in a similar way, and the sign (letter or number) is recorded in the drive 16.

 Thus, only with the correct answers and with the fulfillment of the time standard information is recorded in the drive 15, and in other cases it is considered that the student made a mistake and the information is recorded in the drive 16.

At the same time, information about erroneous responses from the output of element 13 through the decoder 23 enters the corresponding counter 24, when filled, the circuit of element 25 is prepared. The number of counters 24 corresponds to the number of characters (numbers and letters), i.e. each character (letter or number) corresponds to its counter 24. The latter may have a variable memory, i.e. the instructor may at first

E to install a small memory, which means with two or more radio telegraph operator errors, he receives information from switch 4 through the corresponding element 25 and shaper 26 on the board 27, the "hint in the form of a letter, a set of points and a dash and a recommended motive, for example:

-"And where to

-"P ". “Where did you go.

When training is repeated, the counter 24 memory cell by means of a switch (not shown) can be increased by the instructor.

The operation of the simulator is carried out in this mode until the drive 16 is full.

When filled, the drive 16 generates a signal that switches the switch 4 and the output of the encoder 3 is connected. The Morse code signal in this case is recorded in block 17. At the same time, the last pulse of the Morse code signal starts generator 18, which reads (but does not erase) the information (records) from block 17 and accumulator 15, which are analyzed by the second block 19. If the characters match (this This means that the student answered it correctly before), then the generator 18 stops, the information from block 17 is erased and the first character in turn is read from accumulator 16.

The sign (Morse code signal), to which the wireless telegraphist made an error through element 20, switch 4 is presented to the student and recorded in block 7 along the circuit considered earlier. If all the signs to which the wireless telegrapher answered correctly when comparing did not match the sign of block 17, then drive 15, when reading the last sign in turn, stops generator 18 and reads (simultaneously erases) the sign from block 17 through element 20 and switch 4 to the wireless telegraph. In the period of time while the generator 18 is running, the driver 1 does not work. This mode of operation of the simulator occurs until the drive 16 does not consider the last character, which switches the output of the encoder 3 to the initial position, i.e., directly to the input of the imaging unit 5 and block 7.

The proposed simulator allows analyzing the actions of the radio telegraph operator during the training process taking into account the time standards and produces a "hint for removing and fixing the training material

The experience of training radio specialists of the experimental group showed that the time for preparing the Morse code mastering at the first stages of training can be reduced by 25–30%, and the increase in the standard indicators twice as fast.
