Embodiment Construction

[0017] like figure 1 As shown, the whole standing long jump rangefinder system is composed of data acquisition part, data processing part, data display part and power supply parts. During the specific implementation, the data acquisition part is completed by the long jump blanket and the slave module, and the data processing is completed by the host module. The data display part adopts the LED display with the advantage of high brightness. Switching power supply, the power supply of the rangefinder can be automatically switched between battery power supply and mains power supply. The software part is written in C51.

[0018] like figure 2 As shown, the long jump blanket is formed by successively connecting the take-off blanket 1, the transition blanket 2, the measurement blanket 3 and the protective blanket 4. The take-off blanket, the transition blanket, the measurement blanket and the protective blanket are all squares with a side length of 1 meter. 4 meters and 1 meter ...

Abstract

The invention discloses an automatic rangefinder for standing long jump. The rangefinder is composed of a data acquisition part, a data processing part, a data display part and a power supply part, wherein the data acquisition part is connected with the data processing part; the data display part is connected with the data processing part; and the power supply part is respectively connected with the data acquisition part, the data processing part and the data display part. The Automatic rangefinder for standing long jump can automatically measure the score of a landing point nearest to a take-off line and display the score, thereby facilitating the work of an umpire. During the whole measurement process, the action of artificially pressing keys dose not exist, and degrees of intellectualization and automation are higher. The automatic rangefinder can improve the efficiency of sport testing at schools, has low cost and strong practicality, can fully meet the requirements of practical use and is convenient for popularization and use.

Description

technical field [0001] The invention belongs to teaching instruments, in particular to a standing long jump distance measuring instrument used in physical education teaching. Background technique [0002] Standing long jump is a compulsory or elective subject in the physical education examinations in various places, and it is a must-test item for students to meet the sports standards during school. What measure in traditional standing long jump adopts the method of manual measurement, referee needs to repeatedly measure achievement with ruler, reads and records with naked eyes, and the efficiency of work is not high. During the measurement process, the referee judges the results with the naked eye and judges whether it is a foul by stepping on the jumping line. It is inevitable that fatigue will be caused by repeated measurements for a long time, and there will inevitably be errors caused by subjective factors. In order to improve the work efficiency of referees, reduce the...
