The operational control unit 10 is designed to set the operation mode of the Integrated or Standalone device, as well as to change the examination program, and has five outputs: output 51, input of additional information characterizing the type of work performed by the operator and his complaint, output 52 Channel Off , exit 53. “The address of the survey is manual, exit 54, setting the operating mode“ Offline, exit 55, setting the operating mode “Complex.

A device for psychophysiological research is used as follows.

In the process of preliminary preparation of the device using the operational control unit 10, the subject chooses the mode, operation and scope of the examination. There are two modes of operation of the device: "Comprehensive and" Autonomous.

In the “Comprehensive” mode, both post 1 control and post 2 controllers are involved. In this mode, they provide complete control of the operator's state and determine his readiness for work.

Consider the operation of the device in the “Comprehensive.

When the power is turned on, on the command panel 11, the signal "Switching on the monitoring station and the light in the display unit 18 of the monitoring station 2 controller lights up. At the same time, the unit b of psychological measurements and the unit 7 of physiological measurements begin to function, having prepared them for work.

The readiness signals for operation of the physiological measurement unit 7 are fed to the input of the software unit 8, which forms the signal "Token that includes on the command board 11 permission to enter the token 4 in the reading unit 3.

On this signal, the subject injects a token 4 in block 3 of reading. Unit 3 of reading reads the limit values of the norms recorded on the token 4 for all measured parameters, as well as permanent features of the subject (his work number, blood type, etc.) and rewrites them into memory block 5. The boundary values of the norms are obtained by means of statistical processing of the measurement results of monitored parameters on such measuring complexes in the process of the preliminary development of standards.

At the end of the moment of reading the data from the token 4, the signal "Readiness" is generated at the output of the readout block 3, which enters the input of program block 8 and generates the signal "Decision to enter data characterizing the kind of work performed by the subject and his complaint, lighting the corresponding signal on the command board I. On this signal, the person being surveyed, using the operational control unit 10, enters the required information into the memory unit 5.

At the end of this operation in a similar way, software block 8 generates the “Depression for the operation of all blocks of the device. At the same time, the sequence of forming the signals of the "Opening" is chosen in such a way that the gauges of the block 6 of psychological meters are pre-activated, and then the meters of the block of 7 physiological meters. Such a sequence of inclusion of block 6 of psychological measurements and block 7 of physiological measurements allows to increase the reliability of control by detecting not only the "accuracy indicators of the health of the subject by psychological tests, but also the discovery of the physiological price of the achieved performance indicators.

Psychological tests are, as it were, effects on which reactions of the physiological process are determined.

The subject consistently performs

5 all tests and measurements.

The measurement cycle ends when the last meter of the post 1 of the control signal reads "Ready, according to which the program block 8 generates the signal" Opening in memory block 5 of the memory and the signal

0 "The readiness of the post control. The readiness post control signal connects a ring switch 14 post 1 control to a post 2 controllers (and if there are several posts 1 control connects k to post 2 controllers according to the priority of the end of the inspection).

Station 2 of the controller generates in a block 15 a sequence of signals, the address code, which, through the ring switch 14, enters the switch 9 of the operating mode and is converted last into the signals of the polling address. The signals of the polling address are successively received at the control inputs of the memory block 5, the psychological measurement block 6 and the physiological measurement block 7 and interrogate the latter. The control results and individual norms recorded in memory block 5, psychological measurement block 6 and physiological measurement block 7 through the switch 9 of the operating mode and the ring switch are passed to block 15

computation.

In calculation block 15, the results obtained in the control are compared with the corresponding individual norms and registration in block 17 of the registration of all indicators characterizing each parameter (upper and lower limit values of the norm, the measured value and signal

alarms - in case the parameter goes beyond the limits of the individual norm).

Upon completion of the analysis and registration of all permanent features, norms and measured values, depending on the result of the examination, the generalized conclusion goes through the ring switch 14 and the switch 9 of the operating mode 9 to the program block 8, which generates a signal of the overall assessment of the control “To the doctor or“ Free also “Reset common.

With the last signal, all the blocks of the monitoring station 1 are reset, and the token 4 is released from the reading unit 3.

In the case of receiving the signal "To the doctor, the doctor (or operator) additionally, using the registration unit 17 and the manual input and control unit 16, controls the parameters of the patient and can correct the diagnosis.

Post 2 controllers, having finished processing the results obtained at this post of control 1, performs similar operations with the next post of control 1, where the survey cycle has been completed by that time.

Thus, using the device in the Integrated mode allows it to be used for screening and evaluating the suitability of operators for performing certain work during mass surveys.

In the Offline Post 1 control mode, both for monitoring the subject and for training are used.

In this mode, the post 1 control works autonomously without the post 2 controllers. As previously, the test subject initially establishes an examination program using the operational control unit 10. The device performs the remaining operations in the same way as described in the “Integrated. However, after displaying the “Ready post control on the command board 11, read the parameters and compare them with

standards, the operator performs manually. The reading is provided by the operation of the operational control unit 10 and the operation mode switch 9. The results of measurements registers the block 12 of the digital readout.

Thus, the operation of the device in the “Stand-alone” mode allows the subject to test, not loading the doctor, to check his or her spare time during his or her free time or to train individual psychological parameters.

In both modes, the control of psycho-physiological parameters can be carried out according to a full or abbreviated program. A complete program involves the measurement of three psychological characteristics (visual-motor response, tracking response and memory) and three physiological characteristics (body temperature, electrocardiogram parameters and blood pressure parameters). An abbreviated program is needed to shorten the examination time.

A device for psychophysiological research allows to shorten the examination time during mass examinations. The monitoring time of all parameters of one test subject, compared with the available equipment, which takes 16 minutes to measure, is reduced to 4 minutes. At the same time, the measurement time of blood pressure parameters is no more than 120 s; electrocardiogram parameters - no more than 120 s (simultaneously with blood pressure measurement); tracking reactions - no more than 40 s; visual-motor reaction - no more than 15 s; RAM - no more than 70 s; temperatures - no more than 120 s.

The implementation of a device equipped with several control stations makes it possible to increase the number of subjects under one time expenditure per person, which is important when conducting mass surveys under conditions of severe time shortages.
