| 摘 要： | 表面肌电信号（SEMG）的检测分析对临床诊断及康复医学、运动医学等具有重要意义；但是表面肌电信号幅度较小，频率较低，信号的提取比较困难。文章采用虚拟仪器技术构建肌电信号的采集系统，并利用LabWindows／CVI对信号进行处理，利用功率谱K值法对信号进行动作识别，准确度可达85％以上。该研究可作为虚拟仪器的一个开发方向，具有广泛的应用前景。

SEMG Signal Acquisition Based on Virtual Instrument |
| |
| Abstract: | It is important to acquire SEMG signal in clinic diagnose field. But SEMG signal is so faint that it is difficult to pick up. An acquisition system based on Virtual Instrument is introduced in this paper. It can acquire vivid SEMG signal and analysis by LabWindows/CVI,it can recognize action pattern by the method of power spectrum value K, the success ratio can reach 85%. This research can be considered as the future direction of Virtual Instrument. |
