Infrared control audio prompt high jump device

Abstract

An infrared control audio prompt high jump device, a laser emitter is installed on the left pole of the high jump device, the left pole lift switch is connected under the laser emitter, the head of the laser emitter emits red laser light, and the red laser light is received by the laser receiver. The laser receiver is installed on the right pole, the bottom of the laser receiver is connected with the right pole lifting switch, the top of the laser receiver is connected with wires, and the wires are connected with the alarm. When a person jumps over the red laser, as long as the human body blocks the laser, the alarm will alarm, so that the height of the high jump can be accurately measured. The lower part of the laser transmitter and laser receiver is connected with a lift switch, which is convenient for adjusting the height of the high jump. The invention replaces the horizontal pole of the high jump with a red laser, which can not only accurately record the height of the high jump, but also effectively prevent students from cheating when practicing high jump in physical education class, especially to eliminate the fear of the bamboo pole for female students when practicing high jump for the first time. Can effectively improve the achievement of learning high jump.

Description

1. Technical field [0001] The invention relates to a high jump device which uses a red laser instead of a horizontal pole, in particular to an infrared control sound prompt high jump device which can accurately record the height of the high jump. 2. Background technology [0002] Existing high jump devices generally use bamboo poles to record the height of the high jump, which is not only inaccurate, but also cheats when students practice high jump in physical education class, which affects the practice effect. 3. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art, and provide a high jump device that uses red laser instead of a horizontal pole, especially an infrared control sound prompt high jump device that can accurately record the height of the high jump. [0004] The technical solution adopted by the present invention to solve its technical problems is: a laser emitter is installed on the left pole...

AI Technical Summary

Problems solved by technology

[0002] The existing high jump devices generally use bamboo poles to record the height of the high jump. This is not only inaccurate, but also when students practice high jump in physical education class, people often cheat, which affects the practice effect.
