隨著人們越來越注重日常鍛煉，計步作為一種有效記錄鍛煉的手段，被廣泛應(yīng)用于移動終端及智能穿戴設(shè)備中。本方案計步器通常內(nèi)置一個加速度傳感器(Accelerometer)和一個運算單元（MCU），通過加速度傳感器感應(yīng)用戶的加速度變化，然后通過MCU來估算行走的步數(shù)。計步器通常采用三軸加速度傳感器，可以感應(yīng)用戶在三維方向上的運動，且內(nèi)置較為復(fù)雜的計步算法。相對于機械式計步器，電子計步器計步精度更高，抗干擾能力更強，智能手表，智能手環(huán)類產(chǎn)品也都內(nèi)置加速度傳感器和計步算法，方便用戶自己的運動量；計步算法可以分為類，一是峰值檢測算法，二是變換域算法，如FFT，三是濾波算法，四是模式識別算法。根據(jù)所設(shè)計的計步器在人體上布放的位置不同，如腕部、腰部、鞋底等，可以選擇不同的計步算法。FANUC A16B-1002-0860 /03B ROBOT MASTER BOARD *NOS*
