基于STM32单片机的穿戴式坐姿调整器的设计及其实现

“穿戴式坐姿提醒器”是基于STM32最小系统,采用了模块化的设计理念对传统的坐姿矫正器赋予新的定义与本质,使其更加富有智能化与人性化。该“便携式坐姿提醒器”可以通过MPU6050陀螺仪实时感知人体的姿态,该陀螺仪采用了高灵敏度的6轴运动传感器,相对于佩戴者的身体角度,以及躯体动作时的加速度,角速度进行相应的运算,保证了数据的准确性,从而实现对人体的坐姿进行实时的“监视”,在人们出现不良的坐姿时该提醒器就会通过自身所配置的震动电机进行相应程度的提醒。该作品旨在帮助人们改正自身的不良坐姿,减少不良的坐姿给人们带来的不良影响,并佐以Pulse Sensor传感器对使用者的心率进行实时监测。

The wearable sitting-posture reminder, based on the most fundamental STM32 system, adopted the modular design concept to give new definition and essence, is a more intelligentialized and humanized product. By using the high sensitivity of a six-axis motion sensor, the MPU6050 gyroscope is able to provide a real-time perception of human postures. In order to ensure the data accuracy and monitor the wearers^ sitting postures, the gyroscope makes corresponding calculations for user^ s body angles, acceleration of body movements and the angular velocity. Users in undesirable postures will be accordingly informed by the vibrating motors configured through our reminders. Through real-time monitoring by Pulse Sensor,our wearable reminders are conducted to help settle a series of better sitting habits in place of their poor ones so that they would be rid of those unhealthy impacts.
