TELECOMMUNICATION TECHNOLOGIES FOR MONITORING OF FUNCTIONAL STATUS OF DRIVERS DURING THEIR WORK

Abstract

The article is devoted to development of modern telemetric methods for an on-line evaluation of functional status of vehicle drivers during their work. The study of occupational load effect on cardiovascular system was performed with the use of mobile devices included portable sensors and storage device to collect information (smartphone). The developed computer programs were used to calculate spectral indices of heart rhythm variability (HRV). A high self-descriptiveness of wavelet transform for identification offunctional status of cardiovascular system was shown. The reduction of HRV, increase of sympathetic component in regulation and increase of vegetative balance index were observed in drivers by fatigue. The intensity of HRV changes met with occupational load level and characterized degree of individual response as well as allowed to detect exposure induced the stress. A wireless cardiorhythmography is a perspective method for creating personal monitoring system for increasing quality of the drivers' life andfor their health preservation.
