Pull-out type standing long jump automatic distance measuring device

Abstract

The invention discloses a pull-out type standing long jump automatic distance measuring device which can rapidly and accurately measure the long jump distance of a tester in a standing long jump test. The pull-out type standing long jump automatic distance measuring device comprises a movable standing long jump pad, a first pull-out distance measuring rod, a second pull-out distance measuring rod, a jumping area laser emitting module, a measuring area laser emitting module, a jumping area laser receiving module, a measuring area laser receiving module and a main control and display module. The jumping area is provided with a ten-centimeter metering section, and the measuring area laser receiving module can calculate the jumping distance after the a user jumps up and then lands on the ground and displays the jumping distance at multiple terminals. If the laser measuring area is not reached after jumping, the distance can be measured through the scale marks on the standing long jump pad, and the measuring area can be moved forwards by changing the distance of the pull rod, so that the foothold can fall in the laser measuring area. According to the invention, through the pull-out design. the accuracy is high, the measurable range is wide, and the use is convenient.

Description

technical field [0001] The invention relates to the field of sports testing, in particular to a standing long jump distance measuring device. Background technique [0002] According to the "National Physical Health Standards for Students", the standing long jump is a must-test item in the physical fitness tests of universities, middle schools and primary schools. A complete standing long jump action consists of four parts: pre-swing, take-off, vacating, and landing. Through the training of standing long jump, students can exercise their lower body strength and develop their whole-body coordination ability. [0003] In the school physical education test, through the measurement of the two jumping distances, the longest distance is selected as the tester's test score. When measuring the distance, most schools use the scale line on the ground to measure the distance. After each landing, it is necessary to manually check the specific results, which is time-consuming. For quick...

Problems solved by technology

This also brings some disadvantages in the test. Some students are worried about fouling and stay away from the jumping line. Some students cross the jumping line in order to improve their grades, which wastes the time of repeated tests during the test and affects the students' test scores.
