乒乓球运动员训练数据实时采集系统研制与应用

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

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

For the purpose of collecting the swing acceleration data of table tennis players, a real-time acquisition system was designed and developed by adding an acceleration sensor on the handle of table tennis racket. The dynamic real-time parameters of swing speed, displacement and power are calculated and showed intuitively to the coaches and athletes in the form of curved diagrams through kinematic and dynamic analysis. It provides a scientific method for the coaches to obtain table tennis player''s swing power data and a scientific basis for working out a targeted technical and tactical training program or physical fitness training plan. In addition, the training data collected are stored real time in a back-end database in order to facilitate a long-term and scientific tracking of player''s swing power and other data, improve the pertinence and scientific level of training monitoring and promote the performance of table tennis players.
