|
摘要
首先分析了赛艇运动中船桨的受力情况,然后建立了划桨运动力学模型,最终实现了赛艇力学测量分析系统。在船桨上使用传感器采集船桨受力以及船桨在三维空间各方向的加速度数据,经过数据处理与模型分析后,将结果通过无线方式上传到服务器,以供用户查看和分析。系统终端的主控采用STM32系列芯片,用应变片搭建惠斯通电桥完成压力采集模块,用六轴传感器采集加速度数据,用无线广域网通信方式将数据上传到服务器。经实际测试,本系统对于教练员监测运动员运动数据、改进技术动作具有一定指导意义。
First analyzes the force of the oar in rowing, and then establishes the mechanical model of rowing, and finally realizes the measuring and analyzing system of rowing mechanics. Sensors are used on the OARS to collect the force on the OARS and the acceleration data of the OARS in each direction of three-dimensional space. After data processing and model analysis, the results are uploaded to the server through wireless means for users to view and analyze. The main control of the system terminal adopts STM32 series chips, builds wheatstone bridge with strain gauge to complete the pressure acquisition module, collects acceleration data with six-axis sensor, and uploads the data to the server through wireless wan communication. Through the actual test, this system has certain guiding significance for coaches to monitor the movement data of athletes and improve the technical movements.
