The analysis of an electrocardiosignal in a system of data transmission in control office

Among the reasons of accidents on roads there is drivers´ drowsiness. So, it is very important to develop a system that detects an approach of drowsiness and awakes a driver in a case of alarm. The method of detection of drowsiness based on analysis of ECG parameters is convenient and informative enough. A problem of monitoring a driver´s state by controlling his heart rate is actual because this parameter is simple to register. But a threshold of drowsiness can vary for different people. So, it is necessary to control some additional parameters. Research of how parameters of heart rate variability (LF/HF and index of stress of Bayevsky) change in time depending on a state person (during wakefulness, drowsiness and stress) has been carried out. The results showed that there are certain intervals of values characterizing each kind of state. To sum up, it´s suggested to use the analysis of three ECG parameters (HR, LF/HF and index of stress of Bayevsky) in drivers´ drowsiness detecting systems. Using a GPRS data transmission system allows to realize processing and storage of ECG information on a powerful server.
