【摘要】：本文介绍了一种基于三轴加速度计的足部溃疡患者训练系统,利用三轴加速度计和苹果手机平台,引导足部溃疡患者进行各种下肢肌肉群的训练。单片机通过数模转换获得足部训练时三个方向上的加速度值,通过低功耗蓝牙传送到苹果手机上。苹果手机通过应用程序进行加速度数据的预处理、数值滤波和自适应双阈值处理,从而达到识别足部姿态的效果。本文试验结果表明,本文设计的训练系统可以有效地显示患者的训练情况和训练效果,有助于激励患者坚持训练,给医生和患者提供一定的参考数据。
[Abstract]:This paper introduces a kind of training system for foot ulcer patients based on triaxial accelerometer, which uses triaxial accelerometer and Apple mobile phone platform to guide patients with foot ulcers to train their lower extremity muscle groups. The acceleration value in three directions of foot training is obtained by digital to analog conversion, and transmitted to Apple phone by low power Bluetooth. The acceleration data preprocessing, numerical filtering and adaptive double threshold processing are carried out by the application program of the Apple mobile phone, so as to achieve the effect of recognizing the posture of the foot. The experimental results show that the training system designed in this paper can effectively show the training situation and effect of patients, help to motivate patients to persist in training, and provide certain reference data for doctors and patients.
