基于加速度、光电传感器的健身伴侣的研究

Research on Intelligent Fitness Partner based on the Acceleration and Photoelectric Sensors

针对现有计步器功能过于单一的缺点,提出了一种基于加速度传感器的智能健身伴侣。利用一款低成本单芯片3轴加速度传感器MMA7260完成对人体运动信息的提取与分析,由OPT101光电传感器完成对人体心率信号的检测以及分析,以及使用微控制器PIC18F4520完成了自适应计步模型算法,并搭建了心率检测硬件电路。实验结果表明,本文提出的健身伴侣能够准确显示被测者的心率波形,并且计步准确率高达90%以上。

Due to the drawbacks of the single function for the existing pedometers, this paper proposes an intelligent fitness partner based on the acceleration and photoelectric sensors.Through low-cost and single-chip three axles acceleration sensors MMA7260, it extracts and analysis the human＇s sports information. Furthermore, it detects and analyses the human＇ s heart rate signal, by using the photoelectric sensor. Microcontroller PIC18F4520 is used to realize the algorithm of adaptive step counting model, and the heart rate detection circuit is also set up. The experimental results show that the proposed fitness partner can accurately display the heart rate wave of the testee, and the accurate rate is above 90%.
