Abstract

The invention relates to radiotelegraph simulators and can be used as devices for training and professional selection of radiotelegraphists and control system operators, as well as in various psychophysiological studies. The purpose of the invention is to improve the accuracy of the estimates obtained. Introducing a short pulse pulse generator on the fronts, which generates sound stimuli corresponding to the beginning and end of the time interval, and controls the operation of the electroacoustic transducer, improves the accuracy of the operator’s assessment of the quality of the time intervals by eliminating the influence of the energy characteristics of the sound stimuli generated.

i The drawing shows the structure of the simulator.

1 The simulator contains a console 1 operation- Tjopa, consisting of a key 2 and a trigger | a 3 modes of operation, trigger 4, block 5 | AND elements, consisting of two elements And 6 and 7, element OR 8, 9 short pulse generator, generator of 10 fixed frequencies, And element 11, counter 12 errors of pre-transmission, counter 13 of the transformation factor and Block 14: Present to the left educational information I Shaper 9 short impulses - GOB contains delay element 15, Yervy 16 and second 17 prohibition elements and element OR 18

The unit 14 for presenting educational information contains a registration unit 19, a first mode indicator 20 and an electroacoustic converter.

21.

The wireless telegraph simulator works as follows.

When the power is turned on, the register node 19, triggers 3 and 4 are reset, and the generator 10 is started. In the first mode

the operator listens to a standard signal, the beginning and end of which are given by short sound pulses, the same in duration and amplitude. For this, the operator presses the key 2 on the remote control 1. The pulse from the output of the key 2 goes to the counting input of trigger 3 and to the single input of trigger 4. The trigger 3 goes into a state where a high potential appears at its output element AND 6. At the other input of element AND 6, a high potential comes from a single output of trigger 4 and through an open element AND 6 enters the input of indicator 20 of the first mode of operation, illuminates it, and through element OR 8 - at the input of element AND 1.1. and on

input shaper 9 short pulses.

In the imaging unit 9 short pulses, the input signal is fed to the prohibiting input of the first prohibition element 16, the information input of the second prohibition element 17 and to the input of the delay element 15. At the same time, at the output of the second prohibition element 17, a signal appears which, through the element OR 18, arrives at the electroacoustic converter 21 and switches it on. The duration of this signal, and, accordingly, the duration of the sound stimulus is determined by 1bts of the parameters of the delay element 15 and selected within 10-50 ms. The appearance of the signal at the output of the delay element 15 prevents the signal from passing through the inhibit element 17 and turns off the electroacoustic converter 21 accordingly. The duration of the standard signal opens the prohibition element 16 and the signal from the output of the delay element 15 through the prohibition element 16 and the OR element 18 post. It goes to the electroacoustic transducer 21 and turns it on for the time determined by the parameters of the delay element 15.

The operator perceives the time interval specified by short pulses, fixing the beginning and end of the standard signal. The duration of the standard signal is set by changing the frequency of the generator 10 using a switch (not shown) and is selected within 800-1500 ms. The pulses from the output of the generator 10 are transmitted through the open element 11 to the input of the counter 12. The transfer pulse from the output of the counter 12 goes to zero input it translates it into a state in which a low potential appears at its single output. Element And 6 is closed, which causes the formation of the trailing edge of the standard signal in the first mode. At the same time, the indicator 20 of the first mode goes out

In the second mode, the operator presses key 2, maintaining the duration of pressing p. The number n 1,2,3 ... is set in accordance with the methodology of the training manual for the operator. The signal from the output of the key 2 is fed to the counting input of the trigger 3, the unit input of the trigger 4 and the input of the element And 7. In addition, simultaneously with the second contacts of the key 2 connected to the second inputs of the counters 12 and 13, a short pulse is given and installed in initial state. The trigger 3 enters a state in which a high potential appears at its output, which opens the element AND 7o. At the other input of the element And 7, a high potential comes from the key 2 and through the open element And 7 and the element OR enters the input of the shaper 9 short pulses, as well as the input element And 11. With the shaper 9 short pulses and an electro-acoustic transducer 21 are formed sound stimuli, fixing the beginning and end of the time interval reproduced by the operator. In this case, the work of the circuit elements is carried out in the same way as described.

The pulses from the output of the generator 10 are fed through the open element 11 and to the input of the counter 13. From the moment the key 2 is turned on, the element 16 is closed and to the input of the counter. 12, the flow of pulses from the generators stops: ora. 10 The counting results of the counters 12 and 13 are recorded in the registration node 19, where the test results are recorded, in node 19 the magnitude and character are recorded (the time interval is formed with a greater or shorter duration) of admitted error, namely the conversion factor of the standard time interval, which is compared to the t given, and the conversion error.

The use of the invention will make it possible to increase the efficiency of the training and the accuracy of the obtained estimates for the quality of the operator’s transformation of time intervals in comparison with the known simulators by eliminating the influence of the energy characteristics of the generated sound stimuli.
