无线嵌入式计步鞋的设计

Design of Wireless Embedded Pedometer Shoes

目的:设计可以利用无线通讯方式进行步数传输的计步鞋。方法:通过足底的发射端采集压力信号,经信号转换、放大、比较处理后连接到单片机。以AT89S52单片机为核心进行计步,并把步数通过nRF905发送到接收端。结果:接收端具有显示时间、步数信息的第1种计步模式,具有秒表功能、显示路程的第2种跑步模式,具有显示路程、消耗能量的第3种提示模式。结论:基于无线嵌入式的计步鞋的设计具有查看方便、运用灵活、计步准确、功能多样、易于操作的特点。

Objective To design pedometer shoes through wireless transmission step calculation. Methods The transmitting terminals in the soles acquired the pressure signals, and then the signals were transmitted to the SCM after conversion, amplification and comparison. AT89S52 SCM was used for step calculation and then the results were sent to the receiver through nRF905. Results The receiver had three modes, such as the step-calculation mode with the time and stepcalculation result displayed, the running mode with the distance displayed and the function of stopwatch, and the prompt mode with the distance and consumed power displayed. Conclusion The wireless embedded pedometer shoes are muhifunctional, easy to operate and reliable.
