A track and field track mark

Abstract

The invention discloses a racetrack board for the track and field competition terrain and relates to the field of track and field. The racetrack board comprises a racetrack board body, a receiver, a transmitter, a processor and an embedded part. A projection mechanism is arranged in the racetrack board body. The transmitter is arranged in the embedded part. The receiver is arranged at the bottom of the racetrack board body. The projection mechanism is electrically connected with the embedded part through the processor. A combination part is arranged on the end surface of the embedded part. When the racetrack board body is combined with the combination part, the receiver is positioned within the working range of the transmitter. During the construction of a runway, the embedded part can beembedded into a corresponding part of the runway. Meanwhile, the transmitter stores the corresponding runway information. Before a track and field competition, a worker combines the racetrack board body with the combination part in the embedded part, so that the receiver receives the runway information in the transmitter. In this way, the projection mechanism displays the runway information. The worker does not need to specially identify numbers on the racetrack board. The time is saved, and the phenomenon of mistakes during placement is completely eradicated.

Description

technical field [0001] The invention relates to the field of track and field, in particular to a pass card for track and field. Background technique [0002] Track and field, or track and field, is the full name of field, track and all-around competitions. The classification of modern track and field sports is different, mainly including race walking, running, jumping, throwing, and all-around sports composed of some items of running, jumping, jumping, and throwing.

Problems solved by technology

[0004] In view of this, the purpose of the present invention is to propose a track and field race track card to solve the problem that the numbers on the track card in the prior art have been fixed during production, and after the track and field competition is held, it needs to be collected and stored in The sports goods warehouse will be used for the next competition, so that in the next track and field competition, the staff must first identify the number on the track card, and then place it on the track position corresponding to the number in the track card. The staff identification process is not only a waste of time, but it is also easy to make the numbers on the track boards not correspond to the runway technical problems when placing them
