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。
This article describes a three-axis accelerometer-based foot ulcer patient training system, the use of three-axis accelerometer and the Apple mobile platform to guide patients with foot ulcers for a variety of lower extremity muscle training. Microcontroller get through the digital-analog conversion training in three directions when the acceleration value of the Bluetooth low-power transmission to the Apple mobile phone. Apple mobile phone acceleration data through the application of pre-processing, numerical filtering and adaptive dual threshold processing, so as to achieve the effect of recognizing the foot gesture. The experimental results show that the training system designed in this paper can effectively display the patient’s training and training effects, and help to encourage patients to adhere to the training, to provide doctors and patients with some reference data.
