Sleeping posture recognition algorithm of lifting pillow

The invention discloses a sleeping posture recognition algorithm of a lifting pillow. The algorithm comprises a sleeping posture detection sensing belt comprising a plurality of pressure sensors, and an embedded microprocessor, sensor data of a user in a flat sleep state and a side sleep state are collected, a sleep posture judgment limit value is obtained through certain operation of the data, and the value is solidified into a memory of an embedded microprocessor to serve as a boundary value of the flat sleep state and the side sleep state so as to be used for recognizing the sleep posture. 本发明公开了一种升降枕头的睡姿识别算法，包括：一个包含若干压力传感器的睡姿检测传感带，一个嵌入式微处理器；通过采集用户在平睡和侧睡状态下的传感器数据，用这组数据经过一定运算得到睡姿判定限值，把这个值固化到嵌入式微处理器的存储器中作为平睡和侧睡的分界值，用以识别睡姿。
