摘要:

采用仪表放大器和MSP430单片机设计开发了一种简单有效的心电采集测量系统。通过标准2导联,把生物电信号传送到放大器,由于生物电信号比较微弱,信号还需要经过二次放大。利用50 Hz陷波器消除工频干扰;使用单片机采集数据;采用单端模式,测量心电信号测量范围0~600 mV。可以在12864液晶屏上显示,也可通过串口传送到个人计算机。最后为试验系统编写了上位机程序,该系统可以为医生提供病人的远程参考数据。

Abstract:

This paper designs a kind of simple ECG acquisition measuring system with the instrument amplifier and MSP430 single ship.The bioelectric signal is tiny and we obtain it through the standard leads.The tiny signal is amplified by the first level amplifier and then continues to be amplified by the second level amplifier because of the low level voltage of the signal.After the 50 Hz trap circuit,the signal can be passed into the MSP430 through a small circuit model.We use single input AD,the voltage of which ranges from 0mv to 600 mV,to measure the ECG signal.The signal can be displayed on 12 864 Liquid Crystal Display and can also be sent to the pc by the serial port.In the end we program a host computer system interface.This system can provide patient's heart data for the remote doctor.

Key words: MSP430 microcontroller;data acquisition;serial qort;pc
