The inventive device operates as follows.

Before starting work, the device is fixed on a rotary mount and the housing wall, on which the bioradar unit is fixed, is oriented towards the object of non-contact remote biophysical monitoring (user, person performing the activity), and the power is turned on. The user undergoes biometric identification, the results of which are used by the multi-channel signal processor to start recording results associated with that user.

To take into account the current state of the external environment in the process of non-contact remote biophysical monitoring of indicators of a person’s functional state, information from sensors of ambient temperature, atmospheric pressure and air humidity is additionally taken into account.

If necessary, using a wireless data transmission module, the recorded results of multichannel non-contact remote biophysical monitoring of a person’s functional state can be transferred to an external device for interpretation.

Upon completion of the procedure for multichannel non-contact remote biophysical monitoring of a person’s functional state, the device’s power source is turned off.

The claimed device provides multichannel non-contact remote biophysical monitoring of a person’s functional state during activity without the use of contact electrodes, wire sensors and sensors, without creating discomfort or interference with a person’s professional activity.

Thus, the described elements of the claimed device are functionally interconnected and are in structural unity, and the totality of its essential features is unknown from the prior art.

The inventive device is industrially applicable, since it can be implemented by enterprises (organizations) of the medical and radio-electronic industries.
