中文摘要：

由于以智能手机为基础的计步应用系统存在适用运动场合受限、佩戴舒适度不高等缺陷，福州宜美电子公司决定开发一种基于腕表的计步应用系统。针对腕表的计算、存储能力及电量有限，本文设计了一种基于腕表的计步数据采集与同步服务。通过设计腕表采集硬件电路和嵌入式软件以及数据存储策略来提供计步数据的采集服务；设计基于蓝牙低功耗（BLE）的传输协议BLE—Step以提供腕表与智能手机之间计步数据的同步服务。实现对计步数据进行高精度，低功耗的采集与同步，进而实现便携、高舒适度、低能耗的人体运动感知。

英文摘要：

The pedometer applications based on the smart phone existed the problem that movement occasion was limited and it was not very comfortable to wear. So Fuzhou YIMEI Electronics Company decided to develop pedometer applications based on pedometer wrist-watch. Restricted by the limited computing capacity, storage capacity and power of Watch, the paper designed a pedometer data acquisition and synchronization service on the basis of wristwatch. The realization of pedometer data acquisition services was provided by designed hardware of wristwatch acquisition,embedded software and data storage strategy; the designed BLE - Step transport protocol was based on Bluetooth low energy （BLE） to provide data synchronization service between pedometer watches and smart phones. The desig- nation achieved the pedometer data acquisition and synchronization in high - precision and low - power way, thus achieved portable, high comfort and low energy consumption human Motion perception.
