Background technique

In ball games, judging whether the ball goes out of bounds is the key task of the sideline referee. The traditional judging method is often judged by the naked eye, but this method is often unable to give an objective and accurate judgment due to subjective, lagging and other reasons. Especially in the course of the competition, unnecessary disputes between the two sides of the competition are often caused by the result of the ruling, which delays the progress of the competition. In addition, in order to ensure the objectivity of referees, a large number of referees are often needed in ball games, which leads to a waste of manpower, material and financial resources.

Based on the above reasons, relevant people have conducted research on ball games referees. The Chinese invention patent application "Badminton Objective Auxiliary Sideline Referee System" with the application number "2008100723081" is based on video image acquisition technology for adjudication: when a dispute arises during a game, the dispute is resolved through global or local video playback. However, this adjudication method based on video image acquisition technology has high cost and complicated equipment, and the game process needs to be interrupted during the adjudication. In addition, there is also a side cutting machine based on infrared or laser rays, which has the advantages of lower cost and simpler equipment, but it has no intelligent judgment function and needs to make a ruling again according to the equipment alarm reminder.

Fig. 2 is a schematic diagram of the second composition and structure of the badminton court line intelligent referee device according to the present invention. In the first scheme of the smart referee device for badminton sidelines shown in Figure 1 and the second scheme of the intelligent referee device for badminton courtlines shown in Figure 2, the first laser emitter 11 to the tenth laser The arrangement of the transmitter 110, the first laser receiver 21 to the tenth laser receiver 210, the first lower controller 31 to the tenth lower controller 310, and the first wireless transmitter 41 to the tenth wireless transmitter 410 are all the same . The difference is that in the first scheme of the badminton sideline intelligent referee device shown in FIG. 311, the eleventh wireless transmitter 411 can realize the detection of the shuttlecock landing situation on the center line of the two halves of the badminton court; A set of testing facilities are set up on the center line of the two halves of the field, which are: the eleventh laser transmitter 111, the eleventh laser receiver 211, the eleventh lower controller 311, and the eleventh wireless transmitter 411 And the twelfth laser transmitter 112 , the twelfth laser receiver 212 , the twelfth lower controller 312 , and the eleventh wireless transmitter 412 . In practical application, a set of the above-mentioned similar detection facilities can be arranged respectively for all the end lines, side lines and center lines of the two halves of the badminton court.

In the present invention, the laser beams comprising more than 9 laser lines are distributed above each end line, each side line or the center line, and are distributed along the edges on both sides of the each end line, each side line or the center line and directly above the central axis. 1 laser line, three or more laser lines are distributed axially on the side of each end line, each side line or the center line on the side away from the central axis; more than 9 laser lines above each end line, each side line or the center line The laser lines are all located on a plane less than or equal to 25mm from the court ground, and more than 9 laser lines above each end line, each side line or center line are parallel; more than 9 laser lines above each end line, each side line or center line Among the laser lines, the distance between the three or more adjacent laser lines in the middle is less than or equal to 20mm, and the distance between the remaining six or more adjacent laser lines is less than or equal to 25mm.

In the present invention, the i-th laser receiver 2i converts the received laser beam into an electrical signal, specifically: when none of the nine or more laser lines in the laser beam is blocked, the electrical signal corresponding to the laser beam It is a high level or low level of more than 9 bits; when more than 9 laser lines in the laser beam are partially blocked, the electrical signals corresponding to the unblocked laser lines in the laser beam are all 1-bit high level or low level, and the electrical signals corresponding to the blocked laser lines are all 1-bit low level or high level; when more than 9 laser lines in the laser beam are blocked, the corresponding The electric signal is a low level or a high level of more than 9 bits.

In the present invention, the i-th lower controller 3i judges whether the laser beam emitted by the i-th laser emitter 1i is blocked by the shuttlecock according to the received electrical signal, specifically: the i-th lower controller 3i judges whether the laser beam emitted by the i-th laser transmitter 1i is blocked by the received electrical signal. When the beam is blocked, start timing for 50ms. Within 50ms, if the number of blocked laser lines is 1, or if the number of blocked laser lines is 2 and these two laser lines are adjacent, it means that the laser beam is blocked by the shuttlecock .

Alternatively, in the present invention, the i-th lower controller 3i judges whether the laser beam emitted by the i-th laser transmitter 1i is blocked by the shuttlecock according to the received electrical signal, specifically: if the laser line is blocked for less than or equal to 50ms, It indicates that the laser line is blocked by the shuttlecock; if the laser line is blocked for more than 50ms, it indicates that the laser line is blocked by other objects.

Fig. 4 is a schematic diagram of the arrangement of laser beams and laser lines according to the present invention. As shown in Figure 4, in the present invention, the i-th lower controller 3i judges whether the shuttlecock falls inside or outside the boundary according to which one or several laser lines are blocked, specifically:

For each end line and each side line, when there are 9 laser lines in the corresponding laser beam, according to the order from the outside of the badminton court to the inside of the badminton court, the laser lines in the corresponding laser beam are divided into the first laser line J ₁ , The second laser line J ₂ , the third laser line J ₃ , the fourth laser line J ₄ , the fifth laser line J ₅ , the sixth laser line J ₆ , the seventh laser line J ₇ , the eighth laser line J ₈ , the Nine laser lines J ₉ ; if the fourth laser line J ₄ , the fifth laser line J ₅ , the sixth laser line J ₆ , the seventh laser line J ₇ , the eighth laser line J ₈ , the ninth laser line J ₉ If any one of the laser lines is blocked by the shuttlecock, it means that the shuttlecock falls into the bounds; if any one of the first laser line J ₁ , the second laser line J ₂ , and the third laser line J ₃ is blocked by the shuttlecock, it means that the shuttlecock fall out of bounds; if both the third laser line J ₃ and the fourth laser line J ₄ are blocked, then determine whether the third laser line J ₃ or the fourth laser line J 3 is blocked first according to the clock of the i-th lower controller 3i itself. Laser line J ₄ , when the third laser line J ₃ is first blocked, it indicates that the shuttlecock falls out of bounds; when the fourth laser line J ₄ is first blocked, it indicates that the shuttlecock falls into the bounds; the first laser line J ₁ , the second The second laser line J ₂ , the third laser line J ₃ , the fourth laser line J ₄ , the fifth laser line J ₅ , the sixth laser line J ₆ , the seventh laser line J ₇ , the eighth laser line J ₈ , the ninth laser line If any of the laser lines in laser line J ₉ is not blocked by the shuttlecock, the referee will judge manually.

In practical applications, the laser beams and laser lines can also be arranged in the order from the inside of the badminton court to the outside of the badminton court. Correspondingly, for each of the end lines and side lines, the determination of whether the shuttlecock falls into or out of bounds is as follows: if the first Any one of the first laser line J ₁ , the second laser line J ₂ , the third laser line J ₃ , the fourth laser line J ₄ , the fifth laser line J ₅ , and the sixth laser line J ₆ is blocked by the shuttlecock, If any one of the seventh laser line J ₇ , the eighth laser line J ₈ , and the ninth laser line J ₉ is blocked by the shuttlecock, it indicates that the shuttlecock falls out of bounds; if the sixth laser line Line J ₆ and the seventh laser line J ₇ are both blocked, then according to the i-th lower controller 3i's own clock to determine whether the sixth laser line J ₆ or the seventh laser line J ₇ is blocked first, when the sixth When the laser line J ₆ is first blocked, it indicates that the shuttlecock falls into the bounds, and when the seventh laser line J ₇ is blocked first, it indicates that the shuttlecock falls into the bounds. The need for manual judgment remains unchanged.

For the center line, when there are 9 laser lines in the corresponding laser beam, the laser lines in the corresponding laser beam are divided into the first laser line J ₁ and the second laser line in the order of distance from the referee. J ₂ , third laser line J ₃ , fourth laser line J ₄ , fifth laser line J ₅ , sixth laser line J ₆ , seventh laser line J ₇ , eighth laser line J ₈ , ninth laser line J ₉ ; if any one of the fourth laser line J ₄ , the fifth laser line J ₅ , and the sixth laser line J ₆ is blocked by the shuttlecock, it indicates that the shuttlecock falls on the center line; if the first laser line J ₁ , second laser line J ₂ , third laser line J ₃ is blocked by the shuttlecock, it indicates that the shuttlecock falls below the center line; the seventh laser line J ₇ , the eighth laser line J ₈ , the ninth laser line If any one of the laser lines J ₉ is blocked by the shuttlecock, it indicates that the shuttlecock falls above the center line; if both the third laser line J ₃ and the fourth laser line J ₄ are blocked, then according to the i-th lower control The self clock of the device 3i determines whether the _third laser line J3 or the _fourth laser line J4 is blocked at first. When the _third laser line J3 is blocked first, it shows that the shuttlecock falls below the center line. When the line J ₄ is blocked first, it indicates that the shuttlecock lands on the center line; if the sixth laser line J ₆ and the seventh laser line J ₇ are both blocked, then according to the i-th lower controller 3i's own clock to determine the first Whether it is the sixth laser line J ₆ or the seventh laser line J ₇ that is blocked, when the sixth laser line J ₆ is blocked first, it indicates that the shuttlecock falls on the center line, when the seventh laser line J ₇ is blocked first indicates that the shuttlecock falls above the center line; the first laser line J ₁ , the second laser line J ₂ , the third laser line J ₃ , the fourth laser line J ₄ , the fifth laser line J ₅ , the sixth laser line J _6. If any of the seventh laser line J ₇ , the eighth laser line J ₈ , and the ninth laser line J ₉ is not blocked by the shuttlecock, the referee will judge manually.

In practical applications, the laser beam laser lines can also be sorted according to the order from the farthest to the referee. Correspondingly, for the center line, the badminton landing point is judged as follows: if the fourth laser line J ₄ , the fifth laser line Any one of the laser lines J ₅ and the sixth laser line J ₆ is blocked by the shuttlecock, indicating that the shuttlecock falls on the center line; if the first laser line J ₁ , the second laser line J ₂ , and the third laser line J ₃ If any one of the laser lines in J ₇ , J ₈ , or J ₉ is blocked by the shuttlecock, it means that the shuttlecock falls above the center line; Then it indicates that the shuttlecock falls below the center line; if both the third laser line J ₃ and the fourth laser line J ₄ are blocked, then according to the clock of the i-th lower controller 3i, it is determined that the third laser line is blocked first. Line J ₃ is also the fourth laser line J ₄ , when the third laser line J ₃ is first blocked, it indicates that the shuttlecock falls above the center line, and when the fourth laser line J ₄ is first blocked, it indicates that the shuttlecock falls on the said center line. On the center line; if both the sixth laser line J ₆ and the seventh laser line J ₇ are blocked, then according to the i-th lower controller 3i’s own clock, it is determined whether the sixth laser line J ₆ or the seventh laser line is blocked first Line J ₇ , when the sixth laser line J ₆ is first blocked, it indicates that the shuttlecock falls on the center line; when the seventh laser line J ₇ is first blocked, it indicates that the shuttlecock falls below the center line; the first laser line J ₁ , second laser line J ₂ , third laser line J ₃ , fourth laser line J ₄ , fifth laser line J ₅ , sixth laser line J ₆ , seventh laser line J ₇ , eighth laser line J _8. If any laser line in the _ninth laser line J9 is not blocked by the shuttlecock, the referee will judge manually.
