【摘要】 为了揭示脉搏信号与人体疲劳的关系,基于VB语言和Access数据库开发了脉搏信号的采集与分析系统,应用集成化数字脉搏传感器采集信息,小波软阈值方法进行滤波以消除噪声,功率谱分析求得脉搏信号与人体疲劳程度之间的关系。通过实验发现人体疲劳时和清醒时脉搏信号有明显的不同。更多还原

【Abstract】 In order to reveal the relationship between human pulse signals and fatigue,we exploited the pulse signal acquisition and analysis system based on the VB language and Access database,applicated integrated digital pulse sensors to collect information,soft-threshold method of wavelet filtering to eliminate noise,power spectral analysis to find out the relationship between pulse signal and the degree of human fatigue.It was found that there are significantly different of the pulse signals.the human when body through the fatigue and awake.更多还原
