Physical exercise teaching device

Abstract

The invention discloses a physical exercise teaching device, which comprises a first base and a second base, wherein a connecting pipe is arranged on the surfaces of the first base and the second base; a mounting rack is connected to the top end of the connecting pipe via an electric telescopic rod; an infrared transmitter is arranged on the mounting rack at the upper side of the first base; an infrared receiver is arranged on the mounting rack at the upper side of the second base; a first camera is arranged on the side face of the mounting rack; a second camera is arranged at the top end of the mounting rack; a distance sensor is arranged at the bottom end of the mounting rack; and a PLC controller and a display device are arranged on the surface of the second base. According to the physical exercise teaching device, light is transmitted via the infrared transmitter, and then the light is received via the infrared receiver, so that a penetrating movable rod is placed, and subsequently, a circumstance that a movable rod gets dropping due to touch is prevented and safety is guaranteed; and meanwhile, by measuring height via the distance sensor, measuring errors are reduced, and people are facilitated in using.

Description

technical field [0001] The invention relates to the technical field of education and teaching, in particular to a sports teaching device.

[0002] Sports is a complex social and cultural phenomenon. It takes physical and intellectual activities as the basic means, and according to the laws of human growth and development, skill formation and functional improvement, it can promote overall development, improve physical quality and comprehensive education level, enhance physical fitness and improve physical fitness. A conscious, purposeful, and organized social activity that improves athletic ability, lifestyle, and quality of life. It is a relatively common sports event in pole vaulting. Practical training is often required during the teaching of pole vaulting. Education, so you need to use some teaching devices. Although there are some teaching devices for pole vaulting, most of them use movable poles placed at a certain height to allow students to train. Teachers are often required to demonstrate during teaching, but Because the movable rod will fall when it is touched, it will be in contact with the teacher's body, which has certain dangers, and the overall height is mostly measured by a measuring stick, which has a large error, so that it cannot easy for people to use
