Description

Penalty method and system for badminton court line drop points

Technical Field

The invention relates to the field of sports equipment, in particular to a penalty judging method and system for judging a badminton court line drop point.

Background

In a modern high-level badminton game, players can clip on a shot line at an extremely high speed, the problem of penalty judgment of balls falling on the edge of the badminton can be disputed, the problem of penalty judgment of the falling points on the edge becomes the focus of each international high-level badminton game, and people named as Lindan, li Zongwei, tao Feike and the like all happen to strike games after falling due to edge falling point penalty judgment. The introduction of the eagle eye system for solving the problem of point-of-fall penalty was considered 10 years ago in the international association, but the eagle eye system is not used in practice so far, mainly because of a plurality of adverse factors of the eagle eye system: (1) Badminton fields are not as large as football, volleyball and tennis courts, the fields are small, the speed of the badminton is high, and the badminton fields are played back through a video slow mirror, so that penalty is difficult to assist; (2) The system is expensive, and is a great economic burden for the badminton. Therefore, a method and a system for determining the drop point with low cost, accurate penalty determination and timely feedback are needed.

Disclosure of Invention

In order to solve the problems, the invention provides a method and a system for penalty of badminton court line drop points, and the method for penalty of the badminton court line drop points mainly comprises the following steps:

s101: the pressure sensors arranged along the double-side line or the single-side line of the badminton court sense pressure values in real time, and the sensing width of the pressure sensors is consistent with the width of the side lines;

s102: transmitting the pressure value to a drop point real-time interpreter;

s103: the drop point real-time interpreter receives and interprets the pressure value in real time;

s104: according to the pressure value, the real-time point-of-drop interpreter determines whether the point of drop is on the side line? If yes, go to step S105; if not, go to step S107; wherein, the judgment rule is as follows: if the drop point is on the side line, the pressure value will change, and if the drop point is not on the side line, the pressure value will not change;

s105: is it judged whether the shuttlecock falls on the side line? If yes, go to step S106; if not, go to step S107; wherein, the judgment rule is as follows: if the shuttlecocks fall on the edge line, the falling point real-time interpreter displays a circle or an arc on a display screen of the falling point real-time interpreter according to the variation distribution of the pressure value; if other things fall on the side line, the round or semi-round shape is not generated, but other shapes are generated;

s106: judging that the falling point of the badminton is on the sideline;

s107: judging that the falling point of the badminton is not on the edge line.

A penalty system for determining whether a badminton's drop point is on a sideline in a badminton match, comprising:

the caulking groove is positioned on a double-playing side line or a single-playing side line of the badminton court;

the pressure sensor is embedded and bonded in the embedding groove, and the sensing width of the pressure sensor is consistent with the width of the sideline;

the drop point real-time interpreter comprises an electronic component for judging drop points, and the electronic component is connected with a display screen for displaying a graph formed by the variation distribution of the pressure value;

one end of the cable is electrically connected with the pressure sensor, and the other end of the cable is electrically connected with the drop point real-time interpreter;

further, the depth of caulking groove is 1CM, and the width is 6CM.

Further, the pressure sensor sensing width is 4CM +/-10%.

The technical scheme provided by the invention has the following beneficial effects: the method is simple and easy to operate, the system cost is low, the pressure change can be fed back in real time, and the placement penalty of the shuttlecocks is accurate.
