摘　　要：为了实时分析体育训练效果,提高数据采集的输出均衡性,提出基于可穿戴设备的体育训练即时数据采集方法。采用多传感节点信息融合方法进行体育训练即时数据融合,在不同的运动频率下分析体育训练可穿戴设备即时数据输出的振荡特性,根据峰值测量方法进行体育训练可穿戴设备即时数据采集过程的幅值分析和量化融合跟踪识别,建立体育训练可穿戴设备即时数据的特征提取模型,在物联网环境下进行体育训练可穿戴设备数据采集后的融合处理,实现对数据的在线检测和输出控制。仿真结果表明,采用该方法进行体育训练即时数据采集的输出均衡性较好,数据采集的精度接近于1,本文方法的幅值波动范围在-1~1之间,在频偏0 Hz和无单频干扰的情况下,本文方法数据采集的输出误码率为10^(-3),在干扰频率2 000 kHz时达到40 dB,提高了体育训练即时数据的分析和整理能力。In order to analyze the effect of sports training in real time and improve the output balance of data acquisition,a real-time data acquisition method for sports training based on wearable devices was proposed.The multi-sensor node information fusion method is adopted for real-time data fusion of sports training,the oscillation characteristics of real-time data output of sports training wearable devices are analyzed under different movement frequencies,and the amplitude analysis and quantitative fusion tracking and recognition of real-time data acquisition process of sports training wearable devices are carried out according to the peak measurement method.The feature extraction model of real-time data of sports training wearable devices is established,and the fusion processing after data acquisition of sports training wearable devices is carried out in the Internet of Things environment,so as to realize online detection and output control of data.The simulation results show that the output balance of real-time data acquisition in sports training using this method is good,and the accuracy of data acquisition is close to 1.The amplitude of the proposed method fluctuates between-1 and 1,and the output bit error rate of the proposed method is 10-3 when the frequency offset is 0Hz and there is no single frequency interference.When the interference frequency is 2000 kHz,it can reach 40 dB,which improves the ability of analyzing and sorting the real-time data of sports training.
