表面肌电信号测试分析系统的研制

Research and development of the surface EMG detection and analysis system

本文针对假肢等人-机仿生系统肌电控制装置的特点，研制了一种小型表面EMG测试与分析系统。该系统由测试装置硬件和分析软件两部分组成，可选用有线或无线遥测的方法拾取体表EMG活动信息，并利用软件包中的时域、频域和时频分析等多种方法对其采样数据进行处理。该系统为康复工程产品中广泛应用的肌电控制器提供了一个研究与开发平台。

To meet the requirement of developing myoelectric controller for a man-machine systems,a surface elec-tromyography (EMG) detection and analysis system is discussed in this paper. This system consists of two parts-data ac-quisition hardware and signal processing software. In the surface EMG acquisition system both wire and wireless TELEMGare aveailab1e. In the surface EMG processing system various methods are integrated such as the methods in time domain,themethods for frequency analysis,and also including some newly developed metheds,e. g.,wavelet transform and fractal analy-sis. This system provides a useful platform for research and development of the myoelectric controller that is widely used inrehabilitation engineering products.
