本文介绍运动员肌电遥测系统的设计和应用。该系统采用 PAM-FM 体制,可测量100米远处运动员在各种运动状态下八至十二块肌肉的肌电信号和一路关节角度。设备体积小、重量轻、功耗低、携带方便,具有实时观测和记录信号的能力。是运动生理、运动生物力学等学科的研究必不可少的仪器。此外, 还可在医疗、工业中频率为几周至五百周的八至十二路信号的测量中应用。 This article describes the design and application of athlete EMG telemetry system. The system uses the PAM-FM system to measure the EMG signals and all the way to the joints of eight to twelve muscles of athletes at various sports positions at a distance of 100 meters. Equipment, small size, light weight, low power consumption, easy to carry, with real-time observation and signal recording capabilities. It is an indispensable instrument for the research of sports physiology and sports biomechanics. In addition, it can also be used in the measurement of eight to twelve signals in medical and industrial frequency of several weeks to five hundred weeks.
