基于J2ME的脉搏波测量系统设计

为降低成本、提高便携性和二次开发性,设计了一种基于J2ME的脉搏波测量系统。与传统设备昂贵且笨拙的有创测量脉搏信号系统的仪器相比,该方案采用了无创光电容积脉搏波法,使用简易、低成本、通用性高的C8051F330单片机作为信号采集控制单元,在蓝牙手机上使用J2ME显示和存储脉搏信号。结果表明,系统数据误差控制在10%以内,并且系统的成本降低50%以上、体积减少50%以上、二次开发程度高。

Design of pulse wave measuring system based on J2ME

In order to reduce costs,improve portability and secondary development,a system of measuring pulse wave based on J2ME was designed.Compared with traditional invasive measurement of pulse signal device which is expensive and clumsy,this measuring system uses non-invasive photoplethysmography(PPG)method.At the same time,it uses simple,low cost,high versatility C8051F330 MCU control unit as signal acquisition unit,uses J2ME program on Bluetooth mobile phone for displaying and storing the pulse signal.Results show that the system error data is controlled within 10%,cost reduction is more than 50%,volume reduction is more than 50%,and system gains a high degree of secondary development.
