摘　　要：针对目前表面肌电信号采集系统尺寸大，不易携带的缺陷，设计了一种基于ZigBee技术的无线表面肌电信号检测系统。系统由前置放大电路、带通信号调理电路和基于单片机CC2430的无线数据收发电路组成。该电路系统能有效覆盖带宽为10～500Hz的表面肌电信号，实现肌电信号的采集和与上位机的无线射频通信。应用实践表明，此系统能够通过ZigBee无线网络对人体肌电信号进行实时采集，具有移动性和便携性，因此能广泛适用于健康运动监测和医院移动监测等领域。Aiming at the large size and carrying inconveniently tor the current sEMG acquisition system,a wireless sEMG measurement system based on ZigBee technology is designed. The system is comprised of preamplifier circuit, band - pass processing signal circuit and wireless data transceiver circuit based on CC2430. The circuit system can effectively cover the bandwidth of 10- 500Hz sEMG signal and realize the collection of electromyographic signal and wireless communication with PC. The application shows that the system can acquire the sEMG signal of human body in real - time by ZigBee wireless network. Because of its mobility and portability, it can be widely used in health movement monitoring, the hospital mobile monitoring and other fields.
