Abstract

The invention discloses a tennis ball feed and swing speed monitoring device, and relates to a 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 a ball cannot be monitored accurately due to low ball feed regularity in the conventional manual tennis ball feed mode. Suspension ball feed is adopted, and the player can accurately select the hitting point for shooting training; launching tennis ball feed can be performed, a ball feed angle can be arbitrarily selected, and the tennis ball movement track can reappear, so the player can effectively do catching training; and the swing speed of the player can be monitored in a light beam cutting mode. The device is suitable for a tennis ball training process.

Description

technical field [0001] The invention relates to a ball feeding and swing speed monitoring device. Background technique [0002] At present, in the tennis batting training, the batting training methods adopted mainly include two kinds of batting training methods: training with others and using a server to supply the ball. The former method of supplying the ball is greatly affected by human factors, and the regularity of the supply Low; while using the ball machine to supply the ball, the speed of the ball machine is faster, and it is difficult for the hitter (especially beginners) to accurately select the hitting point; moreover, it is currently impossible to accurately monitor the swing speed of the player when he touches the ball; [0003] Utilize athlete's movement information to monitor the tennis ball and the swing speed monitoring device that monitors the athlete's action technical process, has not yet appeared at home and abroad. Contents of the invention [0004] T...
