Standing long jump tester

Abstract

The invention relates to a standing long jump tester which comprises a long jump mat, frames arranged on the two sides of the long jump mat, multiple infrared receiving pipes arranged on the inner sides of the frames at equal interval, a signal amplifier connected with the infrared receiving pipes, a gate circuit which is connected with the signal amplifier and formed by multiple single chip microcomputers, and a main machine connected with the gate circuit. A signal processor and a microprocessor are arranged in each single chip microcomputer, the gate circuit is connected with the signal processors, the output ends of the signal processors are connected with the microprocessors which are connected with a wireless display screen, the microprocessors are connected with a data collection controller through signals, and the data collection controller is in signal connection with a PC through a wireless communication adaptor.

Description

technical field

[0001] The invention relates to a physical fitness testing instrument, in particular to a standing long jump testing instrument. Background technique

[0002] The standing long jump is an important item in the school physical education test. The standing long jump can test the explosive power of human legs. The traditional school test method for standing long jump is to draw a line on the ground, draw the take-off line, draw a ruler line aside, and then visually judge the long jump performance according to the testee's landing point. This method requires the referee to visually judge the results , so the accuracy is low and there are human errors, so it needs to be improved. In recent years, some electronic standing long jump testers have appeared. These electronic standing long jump testers usually include a conductive rubber strip for detecting the position of the landing point. Because the conductive rubber strip has poor detection accuracy and poor durab...
