设计基于无线蓝牙传输的脉搏信号检测系统,系统包括PVDF脉搏传感器、信号调理电路、数据采集电路、蓝牙无线传输模块和上位机数据接收显示模块.实验结果表明,该系统能够对人体的脉搏信号进行实时采集,将数据通过蓝牙无线发送到由J2ME语言编程的手机中,接收到的脉搏信号可在手机上显示波形,并可进一步对信号进行处理,进而实现远程监护.
A pulse signal test system based on wireless bluetooth transmission was designed,in which a PVDF pulse sensor,signal modulation circuit,data acquisition circuit,blue tooth wireless transmission module and displaying module for data received from single-chip computer were included.The test result showed that the system could acquire real-time pulse signal of human being,the data was then sent to mobile phone programmed with J2ME language through wireless bluetooth,the received signal wave form could be displayed on the mobile phone and processed further as well, so that the remote supervision could be realized.
