摘要
对于连续动作的肌电信号 ,从肌电能量的角度提出了一种简单易行的方法 ,将肌电信号自动分割成有动作信号段和无动作信号段 ,为相应的后续处理提供了方便 ,避免了对无动作的信号进行辨识识别运算 ,对提高多自由度肌电假肢的动作识别率有着应用意义。通过对实际连续肌电信号中动作信号的实时提取 。
Generally,each single action is picked up from successive action EMG signal by hand.Then this colleced signal is discriminated after getting its features.But doing by this way is obviously difficult to meet requirements of the myoelectric artificial limb.So this paper presents an easy method from the myoelectric energy point of view.The action signal segments and no-action signal segments are picked up from colleced EMG signal.Thus it is convenient for the relevant follow-up processing,and avoids dealing with no-action signal data .Therefore it is of useful and practical significance for multifunction myoelectric control of prostheses.In this paper,it has been proved that this method is feasible by using it to pick up actual effective action signal.
