摘　　要：介绍一种新颖的心电信号采集仪器的设计方法。仪器采用低功耗单片机MSP430FG439作为信号的前端采集、放大处理器;PC机作为信号滤波、分析的后端处理机,PC机上的MATLAB程序利用串口实时获取心电数据,并对其进行滤波。这样的组合方式充分兼顾了单片机理想的实时测控能力和PC机MATLAB强大的信号处理能力,是一种新颖的智能仪器设计方法。A novel design method of ECG acquisition device is introduced. A low-power single-chip msp430FG439 is used as the front-end signal acquisition and the amplifying processor. PC machines are used as the back-end processor for signal filtering and analysis. The MATLAB program is designed to access and filter with the ECG data through the serial port. This combination fully takes into account the real-time monitoring and control capabilities of the ideal singlechip and PC - MATLAB powerful signal processing capabilities. So it is a novel design method of intelligent instruments.
