STM32和iNEMO模块的高精度计步器设计

设计了一种基于STM32F103RET6和iNEMOMEMS模块的高精度计步器。采用ST公司基于ARMCortex—M3内核的STM32单片机作为核心处理器，iNEMOMEMS模块采集行人行走时腰部的加速度信息，结合人行走时的步态特征，对加速度信息的实时处理实现高精度计步功能。实验结果表明，本计步器能够将步态信息及计步数据可靠地传输至远端PC机，具有体积小、可靠性高、计步准确等优点。

Design of a Pedometer Based on STM32 and iNEMO Module

A high accuracy pedometer is designed based on STM32 and iNEMO module. The system uses STM32F103C8T6 with ARM Cortex- M3 core as the processor. The iNEMO MEMS module is used to measure the acceleration of a pedestrian＇s waist. Combined with the gait feature, the pedometer can measure human step through real-time processing of the acceleration. The gait information and step record are transferred remotely through the SIM300 GPRS data transmission module. Experimental results show that the pedome- ter can meassure human step accurately and the gait information and step record can be transferred remotely to the PC server. This pe dometer has such advantages as small size, high reliability and high accuracy.
