基于单片机的三轴加速度计步器设计与实现

Design and Realization of Three-axis Acceleration Pedometer based on Single Chip Microcomputer

随着人们生活水平不断提高,越来越多人关注自己的身体健康状态,计步器随着时代的需求而产生,基于STC89C51单片机所设计与实现的计步器是通过按键选择控制系统的工作状态,将ADXL345加速度传感器所采集到的数据输送到单片机进行处理,并在LCD1602液晶屏显示,另外,目标步数预设功能、警报功能、路程计算及运动时间显示功能的实现可以更方便用户使用。

With the improvement of people’s living standard,more and more people pay attention to their health in good condition.Pedometers were produced with the need of the times.The pedometer,which was based on the STC89C51 single-chip microcomputer,selected the working status of control system through the keys,and used the ADXL345 acceleration sensors to collect data for microcontroller data processing.The information was displayed on the LCD1602.In addition the functions of presetting the expected number,alarming sound,calculating distance and querying motion time were realized.These functions can be more convenient to the use of customers.
