Description

Game operation system and method {SYSTEM AND METHOD FOR OPERATING A MATCH}

The present invention relates to a game management system and method for determining events that occur during a game.

Generally, table tennis matches can be divided into singles matches between two people and doubles matches between four people. The singles game can be played by players from one side and players from the other side taking turns hitting once and passing the ball to the opposing side. In the doubles game, two players form a team, and the first and second teams take turns hitting once and passing the ball to the opposite side, and the two players on the team take turns hitting the ball once. The game can proceed.

In addition, table tennis matches have a 21-point first-to-win system and an 11-point first-to-win system, and the 11-point first-to-win system is mainly adopted during competitions. In the 11-point first-to-win system, the player or team that scores 11 points first in each set can be the winner of the set. At this time, the total sets in one game are 3 sets, 5 sets, 7 sets, and 9 sets, and different rules are applied for each competition. In the 11-point first-place system, the right to serve is alternated whenever there is a score change of 2 points, and in a 10 to 10 situation, the player or team who scores 2 points in a row, so-called deuce, wins.

The above-mentioned table tennis has established itself as a lifestyle sport that anyone can enjoy, regardless of gender or age. However, as the rules are relatively complex, referees and scorekeepers may be present in official competitions, so nothing unusual may occur, but it is not open to the general public like a club. It can be difficult to concentrate on the game because it is not easy to make accurate decisions in a match.

The distance (a2) from the center of the table tennis table to the end is 1/2 of the horizontal width of the table tennis table and is a constant.

(Formula 2) a ² = b ² + c ²

(Formula 3) a= a ₁ + a ₂

The distance from the table tennis table 10 to the racket 20 is the third separation distance, depending on the embodiment, the distance (a) from the center of the table tennis table 10 to the racket 20 or the distance from the end of the table tennis table 10 to the racket 20. The distance a1 may be used, and the determination time is determined in accordance with the third separation distance.

During a game, even if the scoreboard terminal 70 is fixed during the game, the player can move while holding the racket 20, so the distance c between the scoreboard terminal 70 and the racket 20 is constant. Since it changes to By calculating the distance (a) to (20) and/or the distance (a1) from the end of the table tennis table (10) to the racket (20), and determining the judgment time accordingly, the game is played based on the first separation distance. It is possible to determine the judgment time for events that occur during progress.

Figure 6 is a control flowchart performed by a scoreboard terminal (e.g., scoreboard terminal 70 of Figure 1 or Figure 2) according to an embodiment of the present invention.

Referring to Figure 6, scoreboard terminal 70 may initialize the system at operation 611. The initialization may mean returning all states of the system to the initial state in order to proceed with a new game.

The scoreboard terminal 70, in operation 613, uses a racket (e.g., rackets 20, 30, 80, and 90 in Figure 1 or 2) and a table tennis table (e.g., table tennis table 10 in Figure 1 or Figure 2). The received signal strength can be obtained by measuring the strength of the signal received from. For example, the received signal strength may be inversely proportional to the square of the distance to the racket (20, 30, 80, 90) or the table tennis table (10). In other words, the closer the distance to the racket (20, 30, 80, 90) or the table tennis table (10), the greater the received signal strength, and the closer the distance to the racket (20, 30, 80, 90) or the table tennis table (10) is. The farther away you are, the smaller the received signal strength may be.

In operation 615, the scoreboard terminal 70 determines the distance to the rackets 20, 30, 80, 90 or the table tennis table 10 (e.g., distances (b) and (c) in FIG. 4) based on the received signal strength. )) can be identified. The scoreboard terminal 70 is connected to a communication module provided in the racket 20, 30, 80, 90 (e.g., racket sensor module 21, 31, 81, 91 in FIG. 1 or 2) or the table tennis table 10. Considering the transmission performance (e.g., transmission signal strength) of the provided communication module (e.g., communication module 60 in Figure 1 or 2), a database is prepared that standardizes the actual measured received signal strength for each distance, and the measured reception Distance information can be obtained from the database using signal strength.

In operation 617, the scoreboard terminal 70 uses the distance (c) to the rackets (20, 30, 80, 90) and the distance (b) to the ping pong table (10) to The distance (a) between 80, 90) and the table tennis table 10 can be measured. For example, the scoreboard terminal 70 is a triangle with the table tennis table 10, rackets 20, 30, 80, 90, and the scoreboard terminal 70 as vertices, and the distance (b) corresponding to the two sides and the distance Since we know (c), we can calculate the remaining distance (a).

In operation 619, the scoreboard terminal 70 may determine the decision time by considering the distance (a) between the rackets 20, 30, 80, and 90 and the table tennis table 10. For example, as the distance (a) between the rackets (20, 30, 80, 90) and the table tennis table (10) increases, the judgment time can be set longer, and the longer the judgment time can be set between the rackets (20, 30, 80, 90) and the table tennis table (10) As the distance (a) decreases, the judgment time can be set shorter. This takes into account the flight time from when the ball hits the table tennis table (10) until it reaches the player's racket (20, 30, 80, 90). The scoreboard terminal 70 experimentally obtains the flight time of the ball for each distance and prepares a database in advance with standardized judgment times based on the obtained information, so that the rackets 20, 30, 80, and 90 The decision time can be obtained from the database using the distance (a) between the table tennis tables 10. In this case, the decision time considering the player's movement can be quickly determined, allowing quick decision results.

The scoreboard terminal 70, in operation 621, determines the decision time and various sensors (e.g., impact detection sensor modules 41, 42, 43, 44, racket sensor modules 21, 31, 81, 91) or Depending on the example, the game result may be determined based on the detection signal collected from the net impact detection sensor module 45, and the decision result may be reflected in the score and displayed.

The scoreboard terminal 70 monitors whether the game is over in operation 623, and when it is determined that the game is continuing, operations 613 to 621 may be repeatedly performed, and when it is determined that the game is over. , the related control operation can be terminated.
