Abstract

The invention discloses an external goal table tennis ball feed and swing speed monitoring device and relates to a table tennis ball feed and swing speed monitoring device. The device aims to solve the problems that a batter hardly selects a hitting point accurately, and swing speed of a player touching the ball cannot be accurately monitored due to low ball feed regularity in the conventional manual table tennis ball feed mode. A suspension ball feed mode is adopted, and the player can accurately select the hitting point for hitting training; in the invention, launching table tennis ball feed is performed, the ball feed angle can be selected arbitrarily, and the table tennis ball movement track can reappear, so that the player can effectively do catching training; and the swing speed of the player is monitored by a light beam cutting mode. The device is suitable for the table tennis training process.

Description

Technical field [0001] The invention relates to a table tennis ball supply and swing speed monitoring device. Background technique [0002] At present, in table tennis batting training, the main batting training methods used are: supplying the ball through the coach, practicing with teammates and using the ball machine to supply the ball. The first two ways of supplying the ball are greatly affected by human factors. , The regularity of the ball supply is low; while the ball machine is used to supply the ball, the speed of the ball machine is faster, and it is difficult for the hitter (especially beginners) to accurately choose the hitting point; and it is currently impossible to accurately monitor the player’s touch Swing speed. [0003] The external ball feeder and swing speed monitoring device that uses the athlete's movement information to monitor the athlete's technical process has not yet appeared at home and abroad. Summary of the invention [0004] The present invention is...
