ABSTRACT
Studies have shown that a variety of indexes of electrocardiograph (ECG) signal is related to the fatigue degree of the body, which implies that fatigue driving can be prevented effectively by evaluating the fatigue degree of the driver through monitoring ECG signal. In this paper, we designed a novel system for monitoring drivers ECG, which utilized a direct-contact electrode and a capacitive-coupled electrode. The direct-contact electrode was placed on the steering wheel, which directly contacted one hand of the driver, while the capacitive-coupled electrode on which an operational amplifier was mounted was set on the driver's seat. ECG signals from the two electrodes was acquired and amplified by an instrument amplifier and then sent to the post-processing circuits. A simulation experiment was conducted in our laboratory and ECG signals in resting state, steering manipulation and pedaling motion were measured in this experiment, respectively. Results have shown that ECG signal, especially the R peak, of the subject can be detected by this system except some motion artifacts caused by pedaling.
