specific Embodiment approach 1

[0025] Specific implementation mode 1. Combination Figures 1 to 3 Illustrate this specific embodiment, the internal ball-down type table tennis ball supply and swing speed monitoring device, which includes the air supply pipeline 1 for the limit, the No. 1 air pump 1-4, the air supply pipeline 3 for suspension, and the No. 3 air pump 3-4. 4. Air supply pipeline for injection 4, high-pressure air pump 4-4, limit plate 5, ball supply pipeline 6, ball collecting device 7, baffle plate 8;

[0026] Air supply pipeline 1 for position limitation, air supply pipeline 3 for suspension and air supply pipeline 4 for injection are coaxially sleeved together in sequence from outside to inside; the air inlet located on the side of air supply pipeline 1 for position limitation and the No. The air outlet of 1-4 is connected; the air inlet located at the lower part of the air supply pipeline 3 for suspension is communicated with the air outlet of No. 3 air pump 3-4; The air port is connected...

specific Embodiment approach 2

[0040] Embodiment 2. The difference between this embodiment and the internal ball feeding and swing speed monitoring device described in Embodiment 1 is that it also includes N groups of light beam transceivers and control systems, and N is greater than or a positive integer equal to 2; each group of beam transceiver devices includes a beam generating device 12-1 and a beam receiving device 12-2, and the beam generating device 12-1 and the beam receiving device 12-2 are relatively arranged; the Each group of beam transceiver devices is arranged on the side of the gas supply pipeline 1 for position limitation, and the beam direction emitted by the beam transceiver device is vertically upward; on the same level;

[0041] The light beam generation control signal input end of each light beam generating device 12-1 is all connected with a light beam generation control signal output end of the control circuit 60; Signal input connection.

specific Embodiment approach 3

[0042] Embodiment 3. The difference between this embodiment and the internal ball feeding and swing speed monitoring device described in Embodiment 1 or 2 is that the ball collecting device 7 is funnel-shaped.

[0043] In this embodiment, M rotation air supply pipelines 2 are used to realize the rotation of the table tennis ball during the ball supply process, and by controlling the opening and closing of the corresponding part of the valves in the rotation air supply pipeline 2, the movement of the table tennis ball such as top spin and bottom spin can be realized. , more realistically simulate the operation of table tennis, and the training effect is better.

Abstract

The invention discloses an internal service type table tennis service and swing speed monitoring device and relates to a table tennis service and swing speed monitoring device. The invention aims to solve the problems that the table tennis service regularity is low, a ball striker difficultly selects a ball striking point accurately and a swing speed cannot be accurately monitored when a player touches the table tennis in the conventional artificial table tennis service mode. Due to the adoption of suspension type service, the player can accurately select a touch point to undergo shooting training. Emission-type table tennis service also can be performed, a service angle can be optionally selected, and a motion track of the table tennis reappears; therefore, the player can effectively undergo catch training. The swing speed of the player is monitored in a mode of cutting light beams. 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 internal 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...
