摘要
提出了一种无线运动传感器,它能够根据测量得到的三维加速度值、角速度值、磁感应强度值,实时计算出传感器的三维方向信息。它具有体积小、质量轻、成本低等优点,可以应用在穿戴式计算领域。提出了基于加速度计的电源管理算法,可用于延长传感器的工作时间。实验结果表明:相比于市场上已有的同类传感器,该传感器能够显著降低功耗,延长电池使用寿命。
A wireless motion sensor（WMS） is presented which can calculate 3D orientation information in realtime based on 3D acceleration,3D angular rate and 3D magnetic intensity obtained by measurement.With the advantage of compact size,light weight and low cost,it can be applied in wearable computing field.To extend working lifetime of the sensor,an algorithm of power management based on accelerometer is proposed.The experimental result proves that compared with other existing commercial motion sensor,the proposed sensor can significantly reduce power consumption and prolong battery lifetime.
