基于nRF905和MSP430的惯性传感器无线数传系统设计

Design of wireless data-transfer system for inertial sensor based on nRF905 and MSP430

介绍一种可用于人体跌倒检测的惯性传感器数据无线传输系统,该系统由采集数据的无线传感器节点、接收数据的基站以及监控数据和发配置命令的上位机组成。系统软件采用中断的方法对数据收发实时处理。经测试,上位机和节点之间能够进行可靠性良好、实时性强的数据包和配置命令的无线传输,系统可应用于人体跌倒过程中人体加速度和角速度的实时无线采集。

A wireless data-transmission system for inertial sensor which can be used for body falling-action detection is introduced.The system is composed of wireless sensor node which for data collecting,base-station which for data receiving and upper computer for data monitoring and commands sending.The system software uses interruptible method to realize real-time processing of data receiving and transmitting.By test,the results show that data packet and command can be transmitted wirelessly between the upper computer and node.The system can be used for real-time wireless collection of acceleration and angular velocity of human body during falling activity.
