The disadvantage of this device is the low efficiency of training. The closest to the proposed is a device for training radio telegraphs, containing a pulse generator and an interference generator, the output of which through the first key is connected to the first output of the switching unit whose first and second inputs are: connected to the outputs; the signal generator, the third and fourth inputs of the switching unit are connected to the first and second outputs of the control panel, and the second and third outputs of the switching unit are connected to the inputs of the correct detection counter and the false alarm counter, respectively. The outputs of the display unit 2 are low learning efficiency, since it does not take into account the speed of decoding Morse code signals. The purpose of the invention is to increase the efficiency of learning by evaluating the interpretation of Morse code signals. The goal is achieved by the fact that in a device for training a wireless telephone containing a pulse generator and an interference generator, the output of which is connected via the first key to the first output of the switching unit, the first and second inputs of which are connected to the codes of the signal conditioner, the third and fourth inputs of the switching unit are connected with the first and the third outputs of the control panel, and the second and third outputs of the switch box are connected to the inputs of the corresponding counter of the correct detection and the counter of false alarms, the outputs of which are They are connected to the inputs of the display unit, the second key and the sequentially connected driver of control pulses and are entered. the reaction determining unit, the first OR element in series and the common response counter, the second OR element and the delayed response counter, are connected in series; the output of the pulse generator is connected to the first inputs of the second key and the signal conditioner, the second input of which is connected to the output of the control pulse generator , the first and second inputs of which are connected respectively with the output of the first SHS element and with the first output of the switching unit, and the third input of the driver of control pulses The third output of the control panel and the second inputs of the key and the reaction definition unit, the output of which is connected to the second input of the delayed response counter, the output of the second key are connected to the fifth input of the switching unit, the first and second outputs of which are connected to the inputs of the first OR element. Moreover, the detection unit consists of series-connected time stamp generator, And element and pulse divider, the second input of the And element being the first input of the reaction determining unit, the second input and output of which are respectively the second and the output of the pulse divider. FIG. 1 is a block diagram of the device; in fig. 2 - plots showing his work. The device for training radio telegraphs contains a shaper 1 signals, a switching unit 2, a shaper 3 control pulses, a generator 4 pulses, the first key 5, a block 6 determining the response, the first element IL 7, the remote control 8 controls the counter 9 correct detections, counter 10 false alarms , the display unit 11, the second element OR 12, the counter of general responses 13, the generator 14 interference, the second key 15, the sound generator 16, the electro-acoustic transducer 17, and the signal generator 1 contains the first operational storage, block 18, sec th random access memory block 19, a register 20, address generator 21 marks the Morse code, switch 1 and switch 23 OZUP readable recording unit 2 comprises a switching unit 24 comparison, the trigger control 25, the buttons 26 and. 27, the keys 28 and 29 and the OR element 30, the control pulse shaper 3 includes a two-stage trigger 31 and the signal end fixation node 32, the response determination unit 6 comprises a time stamp generator 33, the first AND 34 element and an adjustable pulse divider 35, a counter 36 delayed responses, and the remote control 8 controls contains buttons 37-39. The device works as follows. . When the power is turned on, counters 9, 10, 13, and 36 are reset, the two-stage trigger 31 (Fig. 2a) is in the one state, 1.c output of which holds the address register 20 (Fig. 2a) in the initial position, and the pulse generator 4 (FIG. 2S, i) o6ec produces the clock pulses to the inputs of the address register 20, the driver of 21 Morse codes and the second input of the driver of 3 pulses, the Superintendent records the signs of the Morse code of the learner to Learn distinguish, and signals, from which. he must distinguish them (similarly sounding or symmetrical). To do this, switch 23 Write read is set to Write. When recording the main signal, switch 22 OSU1-OZUP is set to RAM 1, connecting the information input of the first operative storage unit 18 with the output of 21 Morse code symbols The input of which is connected, for example, to a telegraph key. To control the generated signal, turn on button 26 (listen to the main signal) and press button 39 (Start). When the button 26 is turned on, the first output of the control trigger 25 on video from logical 1 (on the second - O), which, acting on the control input of the key 28, opens it. The output of the operational memory unit 18 via the key 28 and the element OR 30 is connected to the second installation input of the fixing unit 32 and to the input of the sound generator 16 connected to the electroacoustic converter 17, ensuring that the manager can control the signal recorded in the first operational storage unit 18. When you press the button 39 (Start). a positive impulse does not change the state of control trigger 25, since button 26 is pressed, and when button 39 is released, two-stage trigger 31 goes to the zero state, because in it there is a delay in the input pulse duration (time 39) consequently, on, its output according to Vits logical O, which will allow the operation of the register 20 of the address and the node 32 of fixing the end of the signal. The telegraph key forms the elements of the sign (point, tgfe, pause) synchronously with the clock pulses received from the first output of the generator 4 pulses at the input of the generator of 21 Morse code symbols. From the output of the former 2 characters of the Morse code, a sequence of pulses (ones and zeros) is fed through the switch 22 OZUH-OZUP to the information input of the first operational storage unit 18. At the same time, the generated point will record one in one memory cell, and the pause will be zero in memory cell. During the recording of the signal at the output of the fixing end of the signal end, the pulse overflows, but as the first input of the imaging unit 3 of the last pulses (the second installation input of the fixing end of the signal end) comes from the third output of the switching unit 2, the sequence of units and zeros, in which more than three additional orders are not present, and the node 32 of fixing the end of the signal of each 1 is brought to its initial state. At the end of the recording of the signal from the output of the first operative storage unit 18, a sequence of zeros arrives. After eight clocks (since the output of the binary-decimal counter is involved), a single impulse appears at the exit of the signal fixing node 32, which causes the two-stage trigger 31 to its initial state. At its output, it is 1, which translates the address register 20 to the initial position. The button 26 is removed from the fixation, and this completes, with the recording of the axis signals and the sign of the signal into the first operative storage unit 18. Then, the procedure; t record. a descent of sounding (symmetric-) signals-, catch. The switch 22 OZUH- OZUP. set to the position OZUP, connect the information input of the second operational storage unit 19 with the output of the former 21 characters Morse code. To control the formed outgoing sound (symmetric) signal, the button 27 is turned on and the button 39 is pressed. When the button 27 is turned on, the second output of control trigger 25 appears, which affects the control input of key 29, opens it. The output of the second operational storage unit 19 through the key 29 and the element OR 30 is connected to the second installation input of the fixing unit 32 and the signal to the input of the sound generator 16 connected to the electro-acoustic transducer 17, providing the manager with the ability to control the second operation. Memorize the block 19 with a signal. For the rest, the recording of similarly sounding (symmetrical) signals is similar to that described for the main signals. At the end of the recording, the button 27 is removed from fixation. . Switch 23 The write-read is transferred to the read out position. The device is ready to provide information for identification. , To show the signals for a trip, the button 39 is pressed (FIG. 2) The pulse from its output sets the initial state to a pulse divider 35 with a variable counting point and, affecting the second (control) input of the second key 15, allows the passage of the pulses 4 pulse generator to the counting input of the control trigger 25 (Fig. 21). Since the time of pressing the button 39 is slow, a random number of pulses is received at the input of the control trigger 25, which stops the control trigger 25 in a random position (Fig. 2c), since it is removed from either the first or the second output, therefore either key 28 or key 29. When the button 39 is released, the key 15 is closed and the pulse from the generator of 4 pulses is closed. At the input of Control trigger 25, the two-stage trigger 31 stops. goes into the zero state, m1o. The ria of its output is O, which will loosen the operation of the node 32 fixing the end of the signal, register 20 addresses and prohibits the operation of block 6 of the reaction definition. Depending on which key is open, the student is presented. either the main or similar sound (symmetrical) signal (,). At the end of the signal (fig. 2), node 32 of the signal end of cue (fig. 2k) returns the two-stage source igger 31 to the initial state, and the latter translates the address register 20 to the initial position. A single impulse from the output of the two-stage trigger 31 permits the passage of time marks from the generator 33 timestamps through the first element AND 34 to the adjustable divider 35 No. 11 of pulses (Fig. 2A), the division factor of which is chosen depending on the specified time by the opted signal. The subject, after listening to the signal, presses kiosk 37, if he believes that the main signal has sounded, and button 38 (FIG. 2, m), if he believes that a similarly sounding (symmetrical) signal has been sounded. I, - -. With a correct and timely response, a pulse appears at the first output of the comparator unit 24, which is fed to the input of the counter 9 correct detections, where the correct answer is recorded, and through the second element OR 7 to the output of the counter 13 total answers, in which the total number replies. Simultaneously, the pulse from the output of the control panel 8 through the second

71

the OR 12 element arrives at the first input of the counter 36 delayed responses; at 36, however, the number of delayed responses does not record, since there is no signal at the second input of the counter 36 delayed responses (there is no pulse at the output of the adjustable divider 35 pulses, the test subject allotted response time).

If the correct answer is delayed, then at the output of the regulated division of pulses a pulse appears (Fig 2H), which, when a signal is received from the control panel 8, writes back delayed answers 36 to the counter 36 (Fig 2O)

In case of an incorrect and timely response, an impulse appears at the second output of the comparator unit 24, which is fed to the input of the counter 10 false alarms where the incorrect response is recorded, and through the first element OR 7 to the input of the counter 13 general responses.

If the answer is incorrect and untimely, the result is recorded in counters 10 and 13, and in counter 36 of delayed responses.

After each answer, the subject again picks up button 39 (Start) and presents him with a signal as described above.

After presenting, for example, ten pairs. Signals test is suspended. The supervisor analyzes the tester's answers from the counters, and if he is laid down in the standard, the test stops, but not the test — the test continues, and the recognition time increases from 3 to 6. p. The second check is final. .

When using a device for training radio telegraphs, after listening to the signals recorded in the operative memory blocks 18 and 19, the manager determines the quality of the preparedness of the radio telegraphist by the sensitivity parameter displayed on the display unit 11, and by the number of delays (x answers recorded by the counter 36 delayed answers - degree 8

Disable radio reception at a given transmission rate. If, during the transmission of, for example, AO groups, the sensitivity parameter is equal to or less than 0.2, and the number of ea5 held responses does not exceed 2, then in the re-transmission of signals, the time to determine the signs is reduced (by adjusting the pulse divider 35, reducing the division factor).

 In subsequent training, increase the transmission rate (by 1-2 groups per minute) and, depending. from the number of delayed responses, change the time the sign is determined.

5 To test (learn) the reception of signals in the conditions of interference by the first key 5, turn on the generator 14 of lomehie, ensuring that the main signal is transmitted to the learner,

0 similar sounding (symmetrical) signal + noMiexa. The actions of the subject are similar to those described above.

The technical and economic effect of the image is that it is possible to test with the test. operational (expressed by the time specified) ability to identify (recognize) previously presented signals, which allows improving the quality of training and reducing the time for preparing radio telegraphists by selecting groups of students with equal abilities in time decoding of Morse code audio signals. increase the effectiveness of training and achieve a sustainable education link between the perception of the radio telegraph sign

Q and determining its value, which manifests itself in timely and correct response with continuous increase in the speed of presentation of characters, as well as improve the quality of learning by detecting and taking into account the individual abilities of the learner, which manifest themselves in the speed of deciphering of the mischief perceived 1X the auditory organ of the Morse code sound signals, and on this basis, create groups of trainees with one's abilities on perception and processing of information for accelerated preparation.
