Abstract

The invention relates to medical technology and can be used to assess the performance of the operator in man-machine systems. The purpose of the invention is to increase the reliability of research results by taking into account the subject's physiological parameters that exceed permissible values. When a signal changes from one of the sensors 1 to the sensor 1, the element OR 3 is triggered via the corresponding switch 2, and the trigger 4 is set to 1, giving an admissibility signal to continue the experiment on the device output 16. If the number of changed parameters is greater than or equal to the number n, i.e. the state of the subject is critical, then the trigger 4 through element 6 is set to O, and the trigger 10 is set to 1, giving the corresponding signal to output 17.

The accuracy of the signals at the outputs 16 and 17, periodically or at the initiative of the experimenter, to the input 15 is given a signal to monitor the health of the device. This starts the generator 8, and the counter 7 simulates the supply of various signals from sensors 1, while the inputs of the switches 2 switch from sensors 1 to counter 7 - a signal from input 15. If the number of Invention relates to medical equipment, in particular to devices that provide psychophysiological experiments, and can be used to evaluate operator performance in human-machine systems.

The purpose of the invention is to increase the reliability of research results by taking into account the physiological parameters of the subject, exceeding the permissible values.

The drawing shows a block diagram of the device.

The device contains sensors 1 psychological parameters, switches 2, element OR 3, trigger 4, majority element 5, element OR 6, counter 7, generator 8, element OR 9, trigger 10, counter 11, element AND 12, element OR 13, inputs 14 and 15, outputs 16-18 of the device.

The device works as follows.

When a signal appears in one of the sensors 1, a change in one of the physiological parameters of the subject is triggered, element 3 is triggered through the corresponding switch 2, and the trigger 4 is set to 1, giving an output of the experiment to the output 16 of the device.

If the number of changed parameters is greater than or equal to n, that is, the condition of the subject is critical, then trigger 4 through the element OR 6 is set to O, and trigger 10 is set to 1, giving the corresponding signal to output 17.

For the reliability of the signals at the outputs 16 and 17, periodically or at the initiative of the experimenter, the input 15 is given a signal to monitor the health of the device.

This starts the generator 8, and the counter 7 simulates the supply of various combinations of signals from sensors 1. The inputs of the switches 2 switch from sensors 1 to counter 7 by a signal from input 15. In accordance with the number of simulated parameters in each cycle of the counting and subtracting signals the combination corresponds to the number of code combinations of the counter 7 for triggering triggers 4 and 10, then the output of the device 18 shows a signal of the normal operation of the device. Otherwise, such a signal is not generated, and the device is considered to work not reliably. 1 il.

When 7 is triggered, either trigger 4 or trigger 10. Counter 11 either adds or subtracts one. When the counter 7 overflows, the generator 8 stops, the counting stops, and for a time until the end of the signal at input 15, element 12 detects the state of the counter. If the number of summing and subtracting signals in the aggregate corresponds to the number of code combinations of counter 7 for triggering triggers 4 and 10, then the output 18 of the device will signal the normal operation of the device. Otherwise, such a signal is not generated, and the device is considered to work not reliably.
