便携式智能实时运动量测量仪的开发与应用

身体的活动作为人类行为的一个重要部分和人类各种健康和疾病的状况有着一定的关系。人体运动量及能量消耗的测量方法很多,我们从理论和实验两个方面论证了身体加速度绝对值对时间的积分与耗氧量及能量消耗存在的线性关系,基于上述原理设计了一套适用于高原野外运动的便携式能量消耗测量系统,该系统采用最新集成式加速度传感器测量出人体运动的加速度信号,经过信号整合处理并由PIC单片机采集数据后进行分时存储,最终可以在液晶显示器上显示每分钟活动量即累计活动量,该系统采用电池供电,体积小,便于携带,具有广泛的应用价值。

The Development of the Portable Intelligent Real Time Activity Measurement Device

As an important part of Human activity the body movement is related to the health and the dicease status of human beings.There have been many ways to evaluate the body activity.We have demonstrated a new theory that the absolute value of the body acceleration integrated to time is related linearly to the body energy expenditure.Based on this theory a device has been developed to measure the body energy expenditure in the case of field activity.A new integrated acceleration sensor was introduced in this device in order to measure the acceleration signal accurately.The integrated signal is feed into a PIC computer and processed,then the activity amount result is displayed and stored.This device is portable,intelligent and works by batteries.It has wide applicaton value.
