摘　　要：介绍了一种基于蓝牙的便携式三导联心电监护系统的设计。该系统以MSP430FG439微处理器为核心控制芯片,采用高精度的仪表放大器INA321为前置放大,后级放大采用4运放OPA4336,无线收发功能采用国春电器的蓝牙模块GC—02实现,通过合理设计右腿驱动电路,可以有效抑制共模干扰。上位机在VC++6.0的环境中采用MFC编程,实现三导联数据同时显示以及心率的计算、显示。该系统可以实时监测人体的心电信号,共模抑制比高,功耗低,成本小。The design of a portable ECG monitor based on Bluetooth was introduced.The system adopted MSP430FG439 micro-controller as core control unit,and used high-accuracy instrumentation amplifier INA321 as pre-amplifier and OPA4336 as post-amplifier.The data was sent to computer by GC—02 bluetooth module.The design of Right-Leg Drive Circuit can restrain the common-mode interfere efficiently.The software for displaying the 3-lead ECG graph and the heart-rate was written in C ＋ ＋ on the MFC platform.The system can monitor ECG signal real-time.In addition,the system has the advantage of high CMRR,low power and low cost.
