The infrared rangefinder includes a plurality of sub-infrared emitters 5091 that emit infrared rays at angles different from the first jumping line 502 , and sub-infrared receivers 5092 that have the same number as the plurality of sub-infrared emitters 5091 and correspond to positions. The sub-infrared receiver 5092 is integrated with the sub-infrared transmitter 5091. The infrared rangefinder is electrically connected to the processor 101, and is used to measure the distance between the heel of the long jumper and the plurality of sub-infrared receivers 5092 after take-off and landing, and send the distance to the processor 101.

The processor 101 is configured to determine that the long jumper takes off when the first infrared receiver 5085 does not receive the infrared light emitted by the first infrared transmitter 5081 . The first infrared receiver 5085 and the first infrared emitter 5081 can be arranged at a height of 30 to 100 centimeters from the ground. When the long jumper takes off, the body will block the first infrared receiver 5085 from receiving the first infrared emitter. Infrared rays emitted by the 5081. The situation that the tester does not take off from the first jumping line 502 is avoided. When the infrared range finder receives multiple reflected infrared rays, the processor 101 judges that the long jumper takes off and lands.

If any one of the second infrared receiver 5086, the third infrared receiver 5087 and the fourth infrared receiver 5088 does not receive infrared rays during the process from take-off to take-off and landing of the long jumper, the processor 101 judges that the The long jumper cheats, does not calculate the long jump result and controls the alarm 102 to report to the police.

If the long jumper is in the process from take-off to take-off and landing, when the second infrared receiver 5086, the third infrared receiver 5087 and the fourth infrared receiver 5088 all receive infrared rays, the processor 101 calculates and The long jump results of the long jumpers are stored. Specifically, referring to FIG. 4 , the preset rule means that the processor 101 multiplies the distance between the heel of the long jumper and each sub-infrared receiver 5092 after take-off and landing by the pre-stored sub-infrared The sine value of the angle between the infrared rays received by the receiver 5092 and the first jumping line 502 is used to obtain the long jump distance, multiple long jump distances are calculated, and the minimum value among the multiple long jump distances is taken as the long jump result and stored. The calculation formula is:

_Hn = _Ln * _Sinαn .

F=min(H ₁ =L ₁ *Sinα ₁ , H ₂ =L ₂ *Sinα ₂ ,...Hn=Ln*Sinα _n )

Wherein, H _n is the long jump distance, L _n is the distance between the heel of the long jumper and the nth sub-infrared receiver 5092 after taking off and landing, and α _n is the infrared ray emitted by the nth infrared emitter and the first take-off line The included angle is 502, and F is the long jump result.

L _n *Cosα _n <L _line

Wherein, the L _line is the length of the first jumping line 502, and the data outside this condition are ignored.

It should be noted that, in this embodiment, the distance between the heel of the long jumper and the sub-infrared receiver 5092 after taking off and landing is to emit infrared rays from the sub-infrared transmitter of the infrared rangefinder to return to the infrared ray when it encounters an obstacle. The time interval of the sub-infrared receiver 5092 can be obtained by multiplying the infrared propagation speed and dividing by 2.

The processor 101 is configured to determine that the long jumper takes off when the first infrared receiver 5085 does not receive the infrared emitted by the first infrared emitter 5081, and when the infrared rangefinder receives the reflected When multiple infrared rays come back, it is judged that the long jumper takes off and lands. If the long jumper is in the process of taking off and landing, the second infrared receiver 5086, the third infrared receiver 5087 and the fourth infrared receiver 5088 When any one of them does not receive infrared rays, it is judged that the long jumper is cheating, and the long jump result is not calculated and the alarm 102 is controlled to give an alarm. If the long jumper is in the process of taking off and landing, the second infrared receiver 5086 1. When both the third infrared receiver 5087 and the fourth infrared receiver 5088 receive infrared rays, calculate and store the long jump results of the long jumper according to preset rules.

CosA＝(AB ² +L ₁ ² -L ₂ ² )/(2AB*L ₁ )

H ₁ =|L ₁ *CosA-S ₁ |.

Wherein, H ₁ is the long jump distance, and L ₁ is the distance between the heel of the long jumper and the sub-infrared receiver 5092 arranged at point A after the take-off and landing. S ₁ is the position from point A to the first jumping line 502 .

Similarly, F=min(H ₁ , H ₂ ,...Hn)

Among them, F is the long jump result.
