Description

The invention relates to simulators and can be used at the initial stage of training of radio telegraph operators on the key when increasing the transmission rate from 10-12 groups per minute and above.

The aim of the invention is to expand the didactic capabilities of the simulator by working out the skill of rhythm reproduction accuracy in the absence of a prompt by automating the repetition process and switching to another sign, preserving dynamism and reducing training time.

The essence of the invention lies in the fact that after the presentation of the sign during its reproduction, prompts are provided, and then, if the transmission is not affected, the prompt is removed, i.e. The transmission quality (accuracy) is assessed in the absence of a "prompt.

analog key 28 and headphones 29.

The control unit 8 comprises a counter 30, elements OR 31 and 32, a trigger 33 and a delay element 34.

The adder 9 includes a time stamp generator 35, a summation node 36, AND 37-39 elements and a delay element 40.

The pause extraction unit 11 consists of an inverter 41, a single vibrator 42, and an AND element 43.

Block 16 registration contains the shift registers 44 and 45, the adder 46 (modulo two) and the elements And 47 and 48.

The simulator works as follows.

The switches 19 preset the signs (letters, numbers) that the trainee has to work out during training. Turn on the power. The counter decoder 18, the counter 30 and the registers 21, 44 and 45 are reset, the output of the trigger 33 is zero potential, the generators 22 and 27 are turned on. The simulator is ready for operation.

The learner presses the button 1. An impulse from its output (Fig. 8a) is fed to the shaper 5, ensuring the formation of a "Morse code mark" through the OR 13 element at the input of the trigger 3, sets the latter to the zero state if it was in the single state (Fig. 86), through the element OR 12 to the input of the block 8, writing L to the counter 30 (Fig. 8c), through the element OR 12 and the divider 14 to the counter 15, ensuring the fixation of the sign, and to the input of the block 16, control reading of information from the registers 44 and 45 into the indicator 17 (checking the health of the unit).

The impulse received at the input of the imaging unit 5 passes through the OR 25 element to the input of the counter-decoder 18 and provides the appearance at its first output logic “1, which through the switch 19 enters the corresponding inputs of the encoder 20. At the outputs of the encoder 20, the Morse code sign is formed that letter (number), which is set by switch 19, in the form of a binary formalized number. At the same time, the pulse from the output of the element OR 25 goes through the element OR 26 and the element 23 to the input of the register 21, transferring the latter to the parallel recording mode, and passing through the element 24, arrives at the input of the register 21 and records the binary formalized number to the register 21. Clock pulses coming from the output of the generator 22 to the input of the register 21, the sign recorded in it is extended through the output to the information input of element 6, to the inputs of AND 10 and Blod 11 (Fig. 8 g). From the output of element 6, the binary sign combination Morz code is supplied to the control input of analog switch 28, providing a passage with the tone generator 27 to the headphones 29 (VNG. 8d).

At the end of the first sign at the output of block 11, a pulse appears (Fig. 8e), which through the element OR 12 is fed to the input of block 8, recording the second 1 to the counter 30, and passes to the input of the divider 14 (at the output of the signal divider not).

The student, having listened to the presented sound image of the Morse code mark and having his rhythm lowered along the melody, with the help of a telegraph key 2 reproduces it (Fig. 8g).

When the key 2 is pressed, the signal from its output goes to the input of the adder 9 and to the input of the trigger 3, transferring the latter to a single state (Fig. 8 b) and providing the supply from its output of a single potential to the input of the element And 10 and to the input of the adder 9, made the inclusion of the generator 35 (Fig. 8h). A single potential from the output of the trigger 3, entering the input of the former 4, forms an impulse with its leading edge (Fig. 8 and), which, entering the input of the OR element 26, re-extends the sign from the output of the register 21 (Fig. 8d). The check mark from the output of the register 21 enters through the element AND 10 to the input of the node 36 simultaneously with the reproduced sign coming from the output of the element 40 to the input of the node 36, since the delay time of element 40 is equal to the sum of the delay time of elements 23 and 24. The second image of the check mark is reproduced by the headphones 29 (Fig. 8e), providing a "swap to the learner."

In case of equality of the transmitted and check marks (no violation of proportionality) at the output of node 36, there is no unit potential, time stamps from generator 35 to elements 37 and 38 do not pass.

At the end of the reproduction (presentation) of the mark at the output of block 11, a pause pulse appears (Fig. 8e), which through the OR 12 element enters the input of block 8, recording the third "1 in the counter 30. (Fig. 8 c), and divider 14, at the output of which a pulse appears. From the output of the divider 14, a pulse arrives at the counter 15, fixing the next mark presentation, to the input of the block 16, reads the information into the indicator 17, which is not illuminated, because the information in registers 44 and 45 is absent, and through the OR element 13 to the input the trigger 3, setting the latter to the zero state (Fig. 86) and ensuring the supply of a zero potential to the inputs of the element 10 and the adder 9, in which the generator 35 is turned off (Fig. 8h). The transition of the trigger 3 to the zero state causes the disappearance of a single potential, the back front of which forms a pulse at the output of the imaging unit 4 (Fig. 8). This

the impulse arriving at the input of the imager 5 causes the sign to be re-extended from the output of the register 21, which through element 6 enters the electroacoustic converter 7.

At the end of the re-presentation of the sign, a pause pulse from the output of block 11 through the element OR 12 enters the counter 30 and, writing down the fourth “I (Fig. 8c), overflows it. At the output of counter 30, an overflow pulse appears (Fig. 8k), which, through the element OR 32, enters the input of the trigger 33 and translates it into a single state (Fig. 8l). The unit potential from the output of the trigger 33 is supplied to the prohibiting input of the element 6.

The student, after listening to the sign again, using key 2 reproduces it. In this case, "the prompt is missing, since the generated combination of the check mark through the element 6 into the electro-acoustic transducer 7 does not pass.

If the student, in the absence of a “hint, does not allow a fault, i.e. does not violate the proportionality of the sign, then a pause pulse from the output of block 11 (Fig. 8e) enters, as described, into counter 30, and an overflow pulse also appears at its output, which triggers trigger 33 to the zero state (at output - zero potential). The same overflow pulse is fed to the input of the imaging unit 5, providing the learner with a new Morse code sign for identification and reproduction, and after passing through the element 34, returns the counter 30 to the initial state.

If the student violates the proportionality during the transfer of the mark, i.e. generates a sign, the duration of which is less (more) the duration of the control (reference) mark, then the number of time marks on one output of the adder 9 is less (more) than on the other. Timestamps are written to register 45 more (less) than to register 44. When a pause pulse arrives from block 11, a pulse appears at the output of divider 14, which enters the input of block 16 and reads information from registers 44 and 45. When read information at the output of the element And 48 (at the output of the element And 47) an impulse appears, which enters the indicator 17 and illuminates the “Fast (Slow)” banner, which indicates to the learner that it is necessary to transmit more slowly (faster). The same impulse, arriving at the input of the installation of the counter 30, returns it to its original state, while entering the counter 15, fixes the sign.

After this, the trainee will again be presented with the same “hint” sign.

The use of the invention in devices for the training and training of wireless telegraphs extends didactic possibilities.

simulator and increases the effectiveness of training when applying the method of “rehearsing due to the development of the accuracy of reproduction of rhythm by melody first with a hint, and then in the absence of a hint, and automating the repetition process and the transition to another sign. This allows you to maintain high dynamism during the workout, since it eliminates the possibility of scattering attention when repeating the same sign (eliminating the need to press the Start button again) and during the transition to working out a new sign (the installation of Morse code is not required). ) and reduce the training time of radio-telegraphists due to more intensive operation of the simulator in the process of training exercises.

According to the number of repetitions spent on the correct reproduction of the sign without the “prompt,” the student’s ability to develop the skill of reproducing rhythm (proportionality) according to the “melody” is judged.
