摘要
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.关键词
