The invention relates to training and control devices and may find application in the process of training work on telegraph devices.

The purpose of the invention is the expansion of didactic opportunities by providing radio telegraphists with speed work on telegraph devices with a minimum number of errors, taking into account the individual characteristics of radio telegraphers.

Figure 1 shows the structural-electrical circuit diagram of the simulator; Fig. 2 shows the structural-electrical circuit of the comparison unit and the controlled pulse generator.

The simulator contains a controlled pulse generator 1, a shaper 2 codes, a decoder 3, the first board 4 displays, a telegraph 5, a memory register 6, an inverter 7, a clock generator 8, a recorder 9, an adder 10 modulo two, an error counter 11, shift register 12, pulse counter 13, delay element 14, comparison block 15, memory block 16, second display 17, frequency divider 18, timer 19 and third display 20. Moreover, the comparison unit 15 comprises a digital comparator 21, two keys 22 and 23, a positive voltage source 24 and a negative voltage source 25, and a controlled pulse generator 1 — an integrator 26, a converter 27, and a multivibrator 28.

The simulator works as follows.

When the trigger pulse arrives from the output of the controlled generator 1 to the input of the driver 2 codes, the latter generates a code combination to the decoder 3, which converts it into a control signal displayed on the first board 4 of the display in the form of a certain symbol for visual perception by the operator. The code combination from shaper 2 also enters recorder 9, where it is recorded in memory cells. Vosprin in the displayed character displayed on the first board 4 of the display, the operator presses the key corresponding to the displayed character, while the transmitter of the telegraph unit 5 generates a code combination, enter

register code memory 6. At the end of the recording, the start-up message from the output of register 6 of memory passes through inverter 7 and starts the generator of 8 clock pulses. A series of single pulses (the number of clock pulses equal to the number of bits in the recorder 9) from the output of the generator 8 is fed to the input of register 6 and the input of the recorder 9, ensuring the simultaneous output of the information recorded in them to modulator 10 modulo two, used for comparing code combinations.

When the key is correctly pressed, the students pressed the key corresponding to the sign displayed on the first board of the 4 display. The code combinations recorded in register 6 and registrar 9 will be identical, therefore, there will be no signal at the output of adder 10. If the key is pressed incorrectly (the key is pressed does not match the sign displayed on the first board 4 of the display), the compared combinations will be different and a pulse appears at the output of the adder 10, which enters the counter 11 and detects an error.

The information from the error counter 11 is recorded in the register 12 only when a control pulse arrives from the output of the counter 13 pulses, which is a frequency divider following the pulses arriving at its input from the output of the controlled generator 1, to the number m. Thus, counting the number of errors is made during the transmission of a certain number of m characters. Register 12 is reset to the zero state by a pulse coming from the output of the pulse counter 13 and delayed in element 14 for a time sufficient for the operator to press m and keys making a decision at the adder 10 to the correctness of the transmitted codeword.

The information recorded in register 12 is fed to the second display panel 17 to indicate the number of errors and to one of the inputs of the comparison unit 15, to the second input of which is connected the memory block 16 of the allowable number of errors, into which information about the admissible number of erroneous key presses is entered telegraph transmission

m characters. When the operator exceeds the permissible number of errors from the output of the comparator unit 15, a positive polarity voltage is applied to the input of the controlled pulse generator 1, which helps reduce the frequency of the generated pulses. In case the number of errors made by the telegraph operator is less than the number recorded in memory block 16, negative polarity voltage is supplied from the output of comparison unit 15, as a result of which the frequency of impulses generated in controlled generator 1 increases, and consequently also speed increases. Changes in information on the first board 4 displays. When the numbers entering the inputs of the comparison unit 15 are equal, the output voltage at its output is zero (zero) and the frequency of pulse formation in the controlled generator 1 remains a change.

To indicate the transmission rate of telegraph symbols, the pulses from the output of the controlled oscillator 1 are also fed to one of the inputs of the pulse-following frequency divider 18, to the second input of which, at regular intervals, for example, 10 sec, the pulses from the output of timer 19 arrive. the third display panel 20 for indicating the transmission rate.

The multi-pole voltage at the output of block 15 is provided by connecting one of the sources 24 and

25 voltage using keys 22 or 23, controlled by signals from the corresponding outputs of digital comparator 21 (FIG. 2). Depending on the polarity, the voltage from the integrator

26 either increases (when a positive-polarity source 24 is connected to the integrator input 26) or decreases (when a negative-polarity source 25 is connected). In this case, such an integrator is used, the capacitance charging time of which significantly exceeds the period of arrival of pulses from the output of the counter 13. The output voltage from the integrator 26 applied to the input of the converter 27 determines the value of the capacitance added to the multivibrator circuit 28, and therefore the frequency of the generated pulses.

Thus, the simulator contributes to the development of skills of high-speed work on the telegraph apparatus of the student. At the same time, the transfer rate of characters is adapted to the individual abilities of the operator by setting this maximum possible work rate on the telegraph.

Q machine, in which the number of errors allowed (incorrectly transmitted characters) does not exceed the allowable (ie, established in the relevant standards). The use of training equipment 5 Ra ensures maximum efficiency in the preparation of cool telegraph experts, especially on the eve of the competition, when training is needed to develop the highest possible telegram transmission rhythm during

the minimum number of errors.
