Standing long jump automatic test device and test analysis method

Abstract

The invention discloses a standing long jump automatic test device and a test analysis method. Three sections of light curtains are arranged on the two sides of a standing long jump test mat, and the standing long jump test mat is divided into a first take-off zone, a second take-off zone and an induction zone. The standing long jump test mat transmits data to a host through a wireless module, and the host transmits data to a PC machine through a WIFI module. An MCU of the host is connected to a serial port liquid crystal module, a serial port USB module, a voice module and a card reading module. The tiptoe position of a subject in one take-off zone at the last moment before jumping is obtained, and the heel position in the induction zone and closest to the take-off zone within 3 seconds after feet touch the ground is obtained. The value obtained through the subtraction of the heel position in the induction zone and the tiptoe position in the take-off zone serves as the jumping distance. It allows that the tiptoe can move slightly before jumping, and the subject does not break the rule when the moving distance is within the length range of the two light curtains. The automatic test device is high in test accuracy, is convenient to carry, and can conveniently record and store the data.

Description

technical field [0001] The invention relates to a physical fitness test device and a test analysis method, in particular to a standing long jump automatic test device and a test analysis method. Background technique [0002] The 2014 "National Student Physical Health Standards" stipulates that the standing long jump is a compulsory item in the annual physical examination of junior high schools, high schools, and universities. In the traditional standing long jump test, a take-off line is drawn on the ground, a tape measure is placed next to it, and the referee reads with the naked eye and records the students' long jump results. This method has large errors, and data recording, statistics, and management are more troublesome. According to the plan of the Ministry of Education, all test items such as standing long jump should fully popularize intelligent instruments, and be equipped with data management software to provide exercise prescriptions. [0003] At present, the wi...

AI Technical Summary

Problems solved by technology

Conductive rubber uses the method of conduction of the foothold to determine the foothold position. The accuracy of this method is low, and the durability of the conductive rubber is poor.

The infrared tube uses the blocking method to determine the foothold position. The detection angle range of the infrared tube is large, and the infrared ray has a certain penetration, so this method will reduce the accuracy of the measurement.

Moreover, the number of infrared pair tubes is large, and the installation is troublesome

In the existing standing long jump tester, if the position of the toe exceeds the jump line before take-off, it will cause a foul and must be re-measured. The number of measurements is too many, and the students' grades will also be affected.

There is no solution to the measurement error caused by the small movement of the toe and heel before take-off and after landing
