基于位置传感器的中小学生坐姿提醒器设计

Design of sitting posture reminder for primary and middle school students based on position sensor

为了减少因坐姿不正确导致的近视眼疾患病率,以霍尔微耗能开关HAL148L为位置传感器,以扁平微震马达、LED和微型扬声器为提醒元件,设计了一款可适用于不同环境、不同人群的坐姿提醒器。该设计可以在使用者坐姿不良时,通过震动等方式及时提醒使用者,纠正坐姿,预防近视。该提醒器具有独特的静音微震功能,更适合在教室等公共环境中使用,所采用的元器件大部分来源于废旧手机,属于废物回收利用,成本低,环保。该设计可推广作为驾驶员防打盹提醒器。

Many primary and middle school students suffer from myopia. One of the important factors is the unhealthy sitting posture in learning. When the sitting posture is unhealthy, the reminder will remind them to correct their posture to avoid near-sight in time by vibrating and so on. This design is a sitting posture reminder for different environments and various people. The position sensor is based on Hoare switch HAL148 L and the reminder element is based on a flat motor with vibration, with LED and buzzer. The reminder is more suited to use in public environment such as classroom, because it has the mute and vibration function. It is low cost and green. The design also can be a driver reminder to prevent nap with wide usage.
