METHOD AND DEVICE FOR REGISTERING ELECTROCARDIOGRAM AND RHEOGRAM FROM A DRIVER OF AN AUTOMOBILE

摘要

The invention relates to a method of electrocardiogram (ECG) and rheogram data acquisition from a driver of a vehicle and a device for carrying out same, and can be used for determining the physiological condition of the driver, preventing an accident due to a critical physiological condition of the driver, and also can be used in systems of identification and verification of driver identity (authorisation) on the basis of ECG and rheogram data as well as on the basis of information about the rheogram signal carrier phase. The technical result is a reduction of the noise level in ECG signals registered from the hands of the driver of the vehicle by means of a pair of electrodes. In order to achieve said technical result a method for ECG data acquisition from a driver of a vehicle was developed, which comprises: registering an original ECG signal from the hands of a driver by means of at least two electrodes arranged on the steering wheel of the vehicle; registering at least one frequency inducing a noise pickup on the original ECG signal; synthesizing a noise signal (clutter) on the basis of at least one frequency measured, the noise pickup on the original ECG signal and at least one analogous frequency identified in the original ECG signal; subtracting the noise signal from the original ECG signal for obtaining ECG data from the driver of a vehicle.
