Myoelectric signal collection method and device

Abstract

The invention is suitable for the technical field of wearable electronic devices, and provides a myoelectric signal collection method and device. The method comprises the steps that a collection module in a wearable device is controlled to measure the myoelectric signal of a preset human body position with a first collection frequency corresponding to a normal mode; the intensity of the myoelectric signal is obtained, and whether or not the intensity is smaller than a first preset threshold value is determined; if yes, the collection module is controlled to operate under an energy-saving mode,and the collection module is controlled to measure the myoelectric signal of the preset human body position with a second collection frequency corresponding to the energy-saving mode, wherein the second collection frequency is lower than the first collection frequency. According to the method, the unconscious motions of the user can be distinguished from normal training motions, and under a non sports training state, and the collection frequency is reduced by controlling the collection module to measure the myoelectric signal with the collection frequency corresponding to the energy-saving mode to reduce the collection amount of invalid myoelectric signals and improve the collection effectiveness of the myoelectric signals.

Description

technical field [0001] The invention belongs to the technical field of wearable electronic equipment, and in particular relates to a method and a device for collecting electromyographic signals. Background technique [0002] Surface electromyographic signal (hereinafter referred to as electromyographic signal) is a bioelectrical signal generated during muscle contraction. It is the superposition of motor unit action potential (MUAP) in many muscle fibers in time and space. It is used to evaluate the movement of the neuromuscular system. Functional important biological information carrier. At present, EMG signals have a very wide range of application scenarios in the fields of medical research, clinical diagnosis, and rehabilitation. [0003] In recent years, EMG signals have been applied in the field of sports biomechanics. Specifically, during the user's exercise training process, the electromyographic signal of a specific part of the human body can be collected, so that ...
