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 feeding and swing speed monitoring device. Background technique [0002] At present, in the table tennis batting training, the batting training methods adopted mainly include: providing the ball through the coach, practicing with teammates and using the ball machine to provide the ball. The first two methods of supplying the ball are greatly affected by human factors. , the regularity of the ball supply is low; while the ball is supplied by the ball machine, the speed of the ball machine is faster, and it is difficult for the hitter (especially beginners) to accurately select the hitting point; swing speed. [0003] Utilize athlete's motion information to monitor the external ball-down formula table tennis ball and the swing speed monitoring device that monitors the athlete's action technical process has not yet occurred at home and abroad. Contents of the invention [0004] The purpose of the present in...
