摘　　要：目的针对运动科学领域的需求,开发一套便携式肌疲劳实时分析系统。方法系统由信号采集端、FPGA信号处理端和结果显示存储端组成。信号采集端由六通道肌电传感器通过Ag-Ag Cl电极采集人体表面肌电信号,经过1 K采样率ADC转化,由C8051F410控制蓝牙2.0模块发送信号到FPGA信号处理端。FPGA信号处理端接收s EMG信号、解析数据、提取活动段、并计算与肌疲劳分析相关的时频域参数。结果显示存储端通过S3C6410控制LCD显示以及SD卡存储。结果系统实现了六通道s EMG的实时采集以及肌疲劳参数的实时计算、显示和存储。对16位受试者的踢腿运动肌疲劳分析验证了系统的有效性。结论研制的肌疲劳实时分析系统具有强大的实时肌疲劳分析功能,同时具有便于携带、使用方便、可扩展等特点,适用于日常运动疲劳监测。Objective To meet the needs of sports science,a portable muscle fatigue real-time analysis system was developed. Methods The system consisted of a signal acquisition module,a signal processing module and a result display and storage module. The six channel sensors of signal acquisition module collected surface electromyography signal by Ag-Ag Cl electrode. After ADC conversion of 1 K sampling rate,the signal was sent to the FPGA-based signal processing module by Bluetooth 2. 0. The signal processing module received the s EMG data and calculated the parameters related to muscle fatigue analysis. The results display and storage module controlled LCD display and SD card storage through S3C6410. Results The system realized six channels real-time s EMG acquisition and muscle fatigue parameters calculation,display and storage. The feasibility of the system was verified based on the muscle fatigue analysis of kicking movement conducted on 16 subjects.Conclusion The system developed in this paper has strong real-time muscle fatigue analysis function,at same time it is easy to carry,use and be extended.
