基于无线传输的数字铅球设计与应用研究

Applied Research of Digital-shot Sensor Based on Wireless Transceiver

提出一种基于nRF24E1无线收发芯片的三维加速度数字铅球力学采集系统,能够实时获取铅球运动员投掷过程中的三维力信息,并将此力信息与摄像机采集图像信息进行同步,从而对运动员技术动作进行诊断与分析。在此基础上,结合专家指导系统与知识库,对运动员的投掷动作进行分析与指导。

This paper proposes a force information gathering system of three-axis accelerometer digital-shot on the basis of wireless transceiver nRF24E1,which can get three dimensional force information in real time when shot- putters throw the digital-shot.And synchronizes the force information with image information gathering by the camera. On the basis of that,we diagnose and analyze techno-action of the athlete,carry on the analysis and guidance to the athlete＇s throwing movements with experts experience and repository.
