The invention relates to simulators and can be used for professional selection and training of radio telegraph operators.

A device for professional selection and training of wireless telegraphists is known, comprising a block of selector pulses, the output of which is connected to the first inputs of two-input matching blocks, the outputs of which are connected to output pulse counters, a pulse shaper, the output of which is connected to the second inputs of two input matching blocks, the inputs of which are interconnected, a sound generator connected to an electroacoustic transducer, and an impulse counter. The disadvantage of this device is the low efficiency of selection and training of radio telegraph operators.

The aim of the invention is to increase the efficiency of the selection and training of radio telegraphs.

This goal is achieved by the fact that the device has a differential and detector units, the input of the sound generator is connected to the inputs of the pulse generator, a pulse counter and the differential unit, and the output of the differential unit is connected to the input of the selector pulses through the detector unit.

The drawing shows a block diagram of the device.

The device contains a pulse generator 1, made in the form of a telegraph key, a sound generator 2 and an electroacoustic converter 3 for sound control of the signal duration, a pulse counter 4, a differential unit 5 performing the selection of the leading and rear edges of the pulse signal, the detector block b for the selection of positive pulses, a block 7 selector pulses, dividing the signal duration by zones of "leading," accurate and "late actions, two-input circuits 8-10

matches and counters 11-13. The output of the pulse shaper 1 is connected in parallel to the input of the sound generator 2, the output of which is connected to the electro-acoustic transducer 3, to the counter of 4 pulses and the input of the differential unit 5, the output of which is connected to the input of the detector unit 6, its output connected to the input of the unit 7 selector pulses, the first output of which is connected to the input of the coincidence circuit 8, to which the counter 11 "of the leading actions is connected, the second output - to the input of the circuit: 9 matches, to which the counter 12 is connected consequence, the third output - to an input of the coincidence circuit 10, which is connected to the counter 13 "delayed .deystvy, second inputs of coincidence circuits connected together and connected to the output pulse signals .formirovatel 1. The device works as follows. The subject is faced with the task of working at any speed on the telegraph, but in such a way that the durations of pressing the key (sending a signal) and releasing (pause between signals) are equal. At the same time, at the moment of first pressing the key, a pulse is removed from the generator 1 of the pulse signals, which is fed to the input of the sound generator 2 and the electroacoustic converter 3, with the help of which the subject performs sound control of the key pressing duration. At the same time, the same pulse arrives at the input of the differential unit 5, where it is converted into a time interval between pulses corresponding to the leading and trailing edges, then through the detector unit 6, which performs the selection of only positive pulses, the signal arrives at the input of the selector pulses 7, in which the time interval between pulses corresponding to the leading and trailing edges of the original signal is divided but by zones of "leading," accurate and "retarded actions. The selector pulses from the outputs of the block 7 of selector pulses arrive at the primary inputs of two-input circuits 8–10 coincidence, and the selector impulses of the advance zone arrive at the coincidence circuit 8, the exact zones - coincidence circuit 9, delays. - to scheme 10 coincidence. The subject, having sustained a pause equal to the duration of the signal previously sent to him, presses again on the key. In this case, the signal arrives at the second inputs of the coincidence circuits, one of which will have a coincidence of the pressing pulse and the selector pulse, which will trigger the pulse counter connected to the output of this coincidence circuit. At the same time, the same signal, the passage of the differentiating unit 5, the detector unit 6, is fed to the block 7 of selector pulses, where it forms new selector pulses. This cycle is repeated each time the key subject is pressed on the pulse generation unit 1. The total number of the pulses sent to the subjects is counted by counter 4. If the test subject accurately sustained a pause equal to the duration of the signal, then the pressing pulse coincides with the selector pulse of the exact action zone and the signal through the coincidence circuit 9 arrives at the counter 12. then the pressing pulse will coincide with the selector pulse of the zone "ahead of their actions and the signal through the matching circuit 8 enters counter 11. Similarly, if the pause is longer than the signal duration, the impulse of pressing coincides with the selector impulse of the zone of the “late actions” and one will be detected in the counter 13 through the diagram 10. When using the device for the purpose of professional selection, the total readings of the counters are analyzed, thereby revealing the difference between the subjects according to their sense of equality of signal duration and pause. In the process of learning, the subject with the help of counters of “leading and delayed actions” can judge all errors and take measures to eliminate them. The use of the present invention for professional selection and training of radio telegraphists will improve the quality of selection and the effectiveness of training and will lead to a reduction in the cost of training specialists.
