This invention relates to a simulator.

equipment, namely, radio telegraph simulators, and can be used as devices for training control system operators, as well as for professional selection.

The purpose of the invention is the expansion of didactic possibilities and the enhancement of the efficiency of a radiotelegraph simulator by improving operational characteristics based on the formation of a generalized assessment of test results.

The drawing shows a wireless telegraph simulator.

The wireless telegraph simulator contains the operator’s control panel I, consisting of key 2 and trigger 3 operating modes, trigger 4, block AND elements 5, consisting of two elements AND 6 and 7, element OR 8, electroacoustic converter 9, first generator 10. pulses, element. 11, counter 12, prohibition element 13, second pulse generator 14, block 15 bar elements consisting of five prohibition elements 16, indicator 17 of the first operation mode and five counters 18. Converter 9 and indicator 17 the first mode of operation are combined in block 19 presentation of educational information of

The essence of the invention is as follows. Practice has shown that the processing of results is greatly simplified if fuzzy qualitative concepts are used. To do this, it is enough to set five linguistic variables, as which can be large

,

moderately negative

value is about zero, moderately positive and large positive. In this case, the conversion error of the reference signal is normalized in the interval of 0.1. Technically, the normalization operation is completed using a second pulse generator 14. At the output of the second pulse generator 14, a sequence of pulses shifted in time is formed, the duration of which determines the time zones of the introduced ligonic variables. The coincidence of the trailing edge of the signal, formed by the operator with a certain time zone, makes it possible to qualitatively evaluate its actions.

The wireless telegraph simulator works as follows.

When the power is turned on, block 19, triggers 3 and 4 are reset, and generator 10 is started. In the first mode of operation, the student listens to a single pulse. To do this, he presses KJTOM 2 on the remote control 1, the impulse from the output of the key 2 is fed to the counting input of the trigger 3 and to the single input of the trigger 4. The trigger 3 transitions to a state in which a high potential appears at its output AND 6. At the other input of the element And 6, a high potential is supplied from the single output of the trigger 4 and through the open element AND 6 enters the input of the indicator 17, illuminating it, and through the element OR 8 - at the input of the electroacoustic converter 9 and the input of the element 11.

The student listens to the sound image of the pulse. The duration of a single pulse is set by varying the frequency of the generator of 10 pulses using a switch (not shown). The pulses from the generator output 10 pulses enter through the open element 11 to the input of the counter 12. The transfer pulse from the output of the counter 12 enters the zero input of the trigger 4 and its state in which a low potential appears at its single output. Element 6 is closed, which causes the formation of the falling edge of the single pulse that is being listened to in the first mode. At the same time, the indicator 17 goes out.

In the second mode, the student presses key 2, holding down the desired duration of pressing. The signal from the key 2 is fed to the counting input of the trigger 3. a single input of the trigger 4 and to the input of the element And 7. In addition, the signal from the output of the key 2 is fed to the prohibitory inputs of all prohibition elements 16. Simultaneously, from the second contacts of the key 2, connected to the second input of the counter 12, a short pulse is given to set it in the initial state. Trigger 3 enters a state in which a high potential appears at its output, which opens element 7. Trigger 4 also enters a state in which

the output is the current potential arriving at the prohibiting entrance of the prohibition element 13. To the other input of the element And 7 enters high potential from the key 2 and through the open element And 7 and the element OR 8 enters the input of the electroacoustic transducer 9 and to the input of the IM element, the Trainee has the ability to control the impulse formed by hearing.

The pulses from the generator output 10 pulses arrive through the open element 11 to the input of counter 12, the transfer pulse, which fixes the end of the reference signal, arrives at the zero input of trigger A and puts it in a state where a low potential appears at its output. In this case, the prohibition element 13 and the high potential from the output of the element And 7 are opened, the second pulse generator 14 is started. From the moment the key 2 is turned off, the element 11 and the element 7 are closed. This removes a high potential from the inhibit inputs of the prohibition elements 16. The signal present at this point in time at one of the outputs of the second generator 14 pulses, writes one to the corresponding counter 18. Thus, the canteen recorded a qualitative error made by the operator during the first test.

In subsequent tests, the radio telegraph simulator works analogously to the above. Counters 18 reflect the test result using fuzzy qualitative concepts.

Using the proposed wireless telegraph simulator, the processes of analyzing the results and their further use are simplified, in addition, the influence of various errors on the final result is reduced, the possibility of estimating

The state of the operator is his ability to transform time intervals into the usual human quality concepts, as a result. This reduces the time required for the training of operators and increases the efficiency of their work by forming sound recommendations on the organization of work and rest schedules.
