摘要平时大家忙于学习和工作，忽视了身体健康。由此，很多的健身器材随之而 出，计步器具有很好的健身效果，你可以通过计步器来制定详细的健身计划，它 可以督促你跑步，改善体质。
计步器能够测算人们行走的步伐，可以帮助人们监控跑步锻炼。人们行走或 者跑步的时候有很多特性可以采集分析，比如说重力感应和身体加速度，本次计 步器采集人跑步时身体的加速度。淘汰掉老旧的机械式传感器，采用比较先进的 电容式三轴传感器 ADXL345，它可以准确灵敏地采集我们运动时身体的加速度。 然后信号经过这个传感器放大、滤波等流程，传送电信号给单片机。最后这些信 息经过处理器用自适应算法计算，得出准确的步数。单片机 STC89C52 控制液晶 显示计步数。整个器件的工作电流低至 1-1。5mA，耗能很低。系统还有储存和统 计跑步步数数据的功能。

Based on Single Chip pedometer measurement system
Abstract We usually busy studying and working, neglect our health。 Thus, along with a lot of fitness equipment out of the pedometer has a good fitness effect, you can develop a detailed plan by fitness pedometer, it can urge you to run, improve physical fitness。
Pedometer can be estimated that people walking pace, can help people to monitor the running exercise。 People walking or running when there are many features that can be collected and analyzed, for example, gravity sensor and acceleration, when people gather in this pedometer running body acceleration。 Eliminated the old mechanical sensor, more advanced triaxial capacitive sensor ADXL345, it can collect accurate and sensitive to our body movement acceleration。 Then the sensor signal after amplification, filtering and other processes, electrical signals to the microcontroller。 After the last of these information processors calculated using an adaptive algorithm, an accurate number of steps。 SCM control LCD STC89C52 count the number of steps。 Low operating current of the entire device 1-1。5mA, energy consumption is very low。 Storage and systems as well as statistical data of the number of running step function。
Key words: pedometer accelerometer microcontroller
