Embodiment Construction

[0027] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] When performing the ball-to-wall test, the subject needs to be at a certain distance from the wall and hit the volleyball to a specific range on the wall. There are specific regulations for different test levels and genders, for example, the distance between the body and the wall should not be less than 1.5m when throwing a ball against the wall.

[0029] The invention provides a device for automatically counting volleyball balls against the wall. The device is located between the wall and the subject when in use, and the device can automatically count the balls against the wall when the subject meets the assessment requirements. data. Therefore, it saves manpower and avoids human errors in manual statistics,...

Abstract

The invention discloses an automatic counting device for volleyball set-up against a wall and aims to solve the problem of lack of a special technical device for set-up against the wall in the prior art. The automatic counting device comprises a pair of supports arranged on a wall edge, an infrared emitter installed on one support, an infrared receiver installed on the other support and matched with the infrared emitter, and a main control panel electrically connected with the infrared receiver. An infrared signal detection plane close to the wall surface is formed between the infrared emitterand the infrared receiver; and when a volleyball passes through the infrared signal detection plane, a main control panel is used for cumulative counting once. The device in the invention is mainly used for automatic counting of volleyball set-up against the wall, it can be ensured that the counted set-up action conforms to assessment specifications, automatic and accurate counting of a volleyball set-up instrument is realized, the manpower is saved, and manual errors caused by manual counting are avoided, the non-contact detection mode does not influence the motion track of the volleyball, and the examination is guaranteed to be equitable and fair.

Description

technical field [0001] The application belongs to a sports counting device, in particular to a volleyball pad ball counting device. Background technique [0002] Self-cushioning is one of the basic techniques of volleyball. It is a hitting technique that makes the incoming ball bounce off the surface of the pad through the attacking action of the arm on the basis of the coordinated force of the whole body. It is the basis of volleyball. Includes air and wall pads. At present, volleyball self-play is included in the teaching assessment in most provinces and cities. In the self-play assessment, the subjects are required to hit the volleyball to a certain height before they are considered qualified and counted. Therefore, relying on visual inspection cannot guarantee the fairness of the self-play test. To be fair, it is necessary to use special equipment to count the number of times the subjects kick the ball. There have been many counting devices for counting balls in the ai...
