随着人们越来越注重日常锻炼，计步作为一种有效记录锻炼的手段，被广泛应用于移动终端及智能穿戴设备中。本方案计步器通常内置一个加速度传感器(Accelerometer)和一个运算单元（MCU），通过加速度传感器感应用户的加速度变化，然后通过MCU来估算行走的步数。计步器通常采用三轴加速度传感器，可以感应用户在三维方向上的运动，且内置较为复杂的计步算法。相对于机械式计步器，电子计步器计步精度更高，抗干扰能力更强，智能手表，智能手环类产品也都内置加速度传感器和计步算法，方便用户自己的运动量；计步算法可以分为类，一是峰值检测算法，二是变换域算法，如FFT，三是滤波算法，四是模式识别算法。根据所设计的计步器在人体上布放的位置不同，如腕部、腰部、鞋底等，可以选择不同的计步算法。FANUC A16B-1002-0860 /03B ROBOT MASTER BOARD *NOS*
