摘要:

针对表面肌电信号微弱、易受干扰的特点,设计了一种基于ADS1294的表面肌电信号检测系统。系统采用了模拟前端ADS1294电路对表面肌电信号进行滤波、调理和采集,设计了MSP430F169主控制器电路将采集的肌电信号数据传输给上位机,并在LabVIEW环境下,开发了肌电信号检测系统上位机应用程序。该应用程序功能包括信号显示、数字滤波、波形记录及存储回放。实验结果表明,此系统能有效采集及显示表面肌电信号。

According to the weakness and vulnerable of the surface electromyography, a surface electro-myography measurement system based on ADS1294 is designed in this paper. The system uses the ADS1294 circuit to condition and measure the surface electromyography. And a MSP430F169 control circuit is adapted to transfer the measured signal to the upper computer. In the LabVIEW environment, a surface electromyography detection application is designed and developed. The application functions include surface electromyography waveform display, digital filtering, wave-form recording and playback. The validity has been verified by lots of experiment.
