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%%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.
