[0002] In track events such as racing, cycling and running, accurate detection of each athlete crossing the finish line is a key link to ensure the fairness and justice of the competition. This is not only related to the athlete's performance record and ranking, but also an important basis for evaluating the athlete's performance. Although traditional finish line detection methods, such as manual timing and camera capture, meet the needs of the competition to a certain extent, they still have some limitations.

[0003] First, the manual timing method relies on the referee's vision and reaction speed, but in high-speed sports competitions, the moment when athletes cross the finish line is often fleeting, and it is difficult for referees to accurately capture the time when each athlete crosses the finish line. In addition, manual timing is easily affected by the referee's subjective judgment, resulting in errors in the performance records; secondly, although the camera capture method can provide a relatively accurate athlete crossing the finish line picture, it requires post-processing and manual judgment to determine the athlete's crossing time, which not only increases the complexity and cost of the competition, but also in some cases, such as athlete occlusion, insufficient light, etc., may also lead to inaccurate detection results.

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] As described in the background technology, manual timing relies on the eyesight and reaction speed of the referee. However, in high-speed sports competitions, the moment when an athlete crosses the finish line is often fleeting, and it is difficult for the referee to accurately capture the time when each athlete crosses the finish line. In addition, manual timing is easily affected by the subjective judgment of the referee, resulting in errors in the performance records. Secondly, although the camera capture method can provide a more accurate picture of the athlete crossing the finish line, it requires post-processing and manual judgment to determine the athlete's finishing time, which not only increases the complexity and cost of the competition, but also in some cases, such as athlete occlusion, insufficient light, etc., may also lead to inaccurate detection results.

[0029] In order to solve this technical problem, the utility model provides a finish line detection instrument, which is applied to the finish line detection of track and field events.

[0030] Specifically, please refer to Figure 1 , the end point shooting instrument specifically includes:

[0032] The finish line shooting instrument provided by the utility model can realize the laser line interception technology through the shooting of two laser transceiver modules 101. By emitting a laser line across the finish line, when an athlete passes through the finish line, the laser line is intercepted by the athlete's body, thereby triggering a signal, and then recording the athlete's finishing time. It not only has a fast reaction speed and high accuracy, but also can detect the finishing situation of each athlete in real time, greatly improving the fairness and accuracy of the competition.

The laser line interception technology can be realized by shooting with two laser transceiver modules 101, and the laser line is transmitted across the finish line. When the athlete passes the finish line, the laser line is intercepted by the athlete's body, thereby triggering a signal, and then recording the athlete's crossing time.

[0037] The present application uses two laser transceiver modules 101 for counter-shooting, that is, the two laser transceiver modules 101 can respectively receive the laser lines emitted by the other party, thereby realizing dual laser line interception, thereby improving the accuracy of detection.

[0038] Further, such as Figure 1 As shown, two arc grooves 105 are provided on the first connecting frame 102, and fixing bolts 106 are slidably connected in the two arc grooves 105. The ends of the two fixing bolts 106 close to each other are threadedly connected to the second connecting frame 104. After loosening the fixing bolts 106, the first connecting frame 102 and the laser transceiver module 101 can be rotated around the first connecting bolts 103, and the angle of the laser transceiver module 101 can be adjusted. After tightening the fixing bolts 106, the position of the first connecting frame 102 can be fixed.

[0039] Further, such as Figure 1 As shown, a mounting component is connected to a side of the second connecting frame 104 away from the laser transceiver module 101 , and the mounting component is used for mounting the second connecting frame 104 .

After loosening the hand-tightening bolt 109, the height of the shooting mechanism 1 can be adjusted by moving it up and down. After tightening the hand-tightening bolt 109, the position of the mounting frame 108 can be fixed, thereby enabling the supporting and protecting mechanism 2 to support the shooting mechanism 1.

[0044] Further, such as Figure 2-Figure 3 As shown, a connecting piece is arranged between the first support plate 201 and the second support plate 202, and the connecting piece includes two connecting seats 203 fixedly installed on the top of the second support plate 202, and a second connecting bolt 204 is inserted and connected between the two connecting seats 203, and the outer surface of the second connecting bolt 204 is sleeved with a connecting plate 205 located between the two connecting seats 203, and the connecting plate 205 is fixedly connected to one end of the first support plate 201. After loosening the hand nut 206, the first support plate 201 can rotate around the second connecting bolt 204, which can not only adjust the pitch angle of the laser transceiver module 101, but also rotate the first support plate 201 to cover the top of the protective support box 208. This arrangement enables the first support plate 201 to cooperate with the protective support box 208 to improve the protection effect of the laser transceiver module 101.
