乒乓球运动员训练数据实时采集系统研制与应用

Development and Application of a Real-time Data Collection System for Table Tennis Players

通过在乒乓球球拍的拍把上加装加速度传感器,并开发相应的击球力量训练数据实时采集系统,实时采集乒乓球运动员训练时挥拍的加速度数据,通过运动学和动力学分析,得出乒乓球运动员挥拍的速度、位移和力量等实时动态参数,并以曲线的形式实时、直观地显示给教练员和运动员,为教练员了解乒乓球运动员挥拍的力量等数据提供科学手段,为制订有针对性的技战术和体能训练计划提供科学依据。此外,采集的训练数据实时存储在后台数据库中,便于对运动员的击球力量等数据进行长期、科学的跟踪,以提高运动训练监控的针对性和科学化水平,提高乒乓球运动员的运动水平和比赛成绩。

For the purpose of collecting the swing acceleration data of table tennis players, a re-al-time acquisition system was designed and developed by adding an acceleration sensor on the han-dle of table tennis racket. The dynamic real-time parameters of swing speed, displacement and pow-er are calculated and showed intuitively to the coaches and athletes in the form of curved diagramsthrough kinematic and dynamic analysis. It provides a scientific method for the coaches to obtaintable tennis player＇s swing power data and a scientific basis for working out a targeted technical andtactical training program or physical fitness training plan. In addition, the training data collected arestored real time ina back-end database in order to facilitatea long-term and scientific tracking ofplayer＇s swing power and other data, improve the pertinence and scientific level of training monitor-ing and promote the performance of table tennis players.
