博士 === 國立交通大學 === 機械工程系所 === 103 === This study provides a practical procedure and a noise immunity method for detecting the vital signs of a person in a vehicle. Velocity sensors that are convenient and accurate at acquiring data are adopted to detect the involuntary body vibrations called Ballistocardiac effect. Two kinds of methods have been proposed and compared to reduce the ground noise effects when the experiments were conducted in extreme environments. During the experiments, a ground sensor are also used to measure the vibrations of ground surface for calculating the vehicle body response. The complete detecting system and signal processing method are verified through the experiments conducted with various types of vehicles and environments. The experiment results also provides a standard procedure to process the signals measured from other types of vehicles.
