As shown in FIGS. 4, 5, and 6, the automatic table tennis score display method of the automatic table tennis score display system according to another embodiment of the present invention is a method of automatically displaying the table side table vibration value and the seat side vibration value A first step of calculating a score according to the order of the court area in which the vibration should be sensed, according to whether or not the table pavement court area and the same court area where the vibration was last sensed are continuously sensed, And a third step of receiving and displaying the score signal.

Now, a table tennis score automatic display method of a table tennis score automatic display system according to another embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The automatic method of measuring the table tennis score of the automatic table tennis score system according to the present invention shown in FIG. 4 is as follows.

First, the seating area and the right side of each court area of the table tennis table are determined, and the team determining the sub area is determined. For example, you can decide to have alternate alternates of two for each team. In FIG. 4, although the automatic method of measuring the table tennis score is shown in the case of the sub-region, it does not mean that the child has to have the sub-region when applying the table tennis, and is applicable to the game without the sub-region.

Once a match starts, as soon as a player (or a player) of a team with a sub-title bounces the table tennis ball on the table, the vibration of the left and right sides is measured in real time. That is, the control unit 120 of the score measuring unit 100 resets the sub number to '0' and sets the court area of the team having the subpopulation among the table pennis table seat side and the right side table as the sub side surface (S10) Measures the seat vibration value and the right side vibration value (S12). The display unit 230 of the score display unit 200 displays a team having a sub-title via the sub-display unit 233. [

For example, if a team on the right side of the table tennis team has a sub-area, the right side is set as the sub side surface, and the right side player starts the game through the serve. When a normal serve is performed, the table tennis ball will touch the right side and then move to touch the seating side.

If the vibration of the sub side surface, that is, the right side, is detected by the vibration value measured by the sensor unit 110 of the score measuring unit 100 (S14), the controller 120 determines that the tennis ball I.e., during the average time to move to the seating surface, the vibration of the mating surface, i.e., the seating surface, is sensed. If the vibration of the surface of the other side is sensed within a predetermined time after the detection of the sub side surface vibration (S16), the controller 120 judges that the normal sub is performed and determines whether rally is continued to measure whether the left side or the right side is vibrated (S18).

However, when vibration is not detected for a predetermined time on the right side having the sub-zone or when the left side vibration is detected in the state where the right side vibration is not detected, the controller 120 determines that the normal sub- (S26).

In step S18, when the vibration on the sub-side surface is sensed, the control unit 120 determines whether the sub-side surface and the mating surface are vibrated or not (S22).

However, if the vibration of the sub side surface is not sensed for a predetermined time in step S18, the control unit 120 determines that the sub side team has won and increases the score of the sub side team (S28).

In step S22, when the vibration on the sub side surface and the mating surface is measured, if the vibration of the mating surface is detected, the control unit 120 of the score measuring unit 100 determines that the next rally is continued, Whether the surface is vibrated or not is measured (S18).

However, if the vibration of the opposing side is not sensed at step S22, the control unit 120 determines that the opponent team has won and increases the score of the opposing team (S26).

After increasing the score in step S26 or S28, the score measuring unit 100 transmits the score to the score display unit 200 via short-range wireless communication (S30). Then, the control unit 120 of the score measuring unit 100 determines that one game has ended and increases the number of sub-games by 1 and confirms whether the increased sub-number represents '2'. If the increased sub-number does not indicate '2', the control unit 120 proceeds to step S12 to start a new one-time game and again measure whether the sub-side surface or the other side surface is vibrated (S12).

However, if the increased sub-number indicates '2', the controller 120 determines that the sub-region should be handed over to the opposing team, and the process proceeds to step S10. In addition, the score measuring unit 100 may control the sub-display change display with the score display unit 200 or may display the score display unit 200 that the sub-region has been changed to the opposing side team without the control of the score measuring unit 100 have.

In each step of measuring the vibration value of the ping-pong table, when it is judged which of the sub side surface and the counter side surface is in the vibration of the team court area, the control part 120 determines whether the same court area is continuously sensed before the table tennis ball moves to the opposite side surface And when the vibration of the same court area is continuously detected, the score of the team which is the opposite of the court area continuously sensed is increased.

On the other hand, when the player of the sitting team starts a game through the serve, the score measuring unit 100 measures the score in this manner.

It is also possible to measure the score in such a flow even if it falls on the net during a sub-failure or a rally.

As described above, the automatic table tennis score display system according to the present invention measures the vibration value generated when the table tennis ball is touched to the ping-pong table, detects whether the vibration is detected according to the order of the court area where the vibration should be detected, Before the table tennis ball moves to the opposite court area, it is confirmed which vibration of the same court area is consecutively detected, the score is calculated according to the confirmation result, and the calculated score signal is transmitted through the near field wireless communication will be.

5 is a flowchart illustrating an operation of the score display unit 200 of the automatic table tennis score display system according to the present invention.

The score display unit 200 sets a set number and an ending score according to the user's input (S40), receives the score signal calculated from the score measuring unit 100 via the short range wireless communication unit 210, (S42).

The score display unit 200 confirms whether the seat face score or the right side score is equal to the end score (S44). If the seating score or the score on the right side is equal to the end score, it is judged that one set of games has ended. In addition, the score display unit 200 may check whether the current set is the same as the set number, and display the end of the match if the number is the same as the set number.

However, if it is determined in step S44 that the seat face score or the right side score is not equal to the end score, the score display unit 200 determines whether the sitting score or the right side score is one less than the end score (S46). If the seat face score or the right side score is less than the end score, the score display unit 200 proceeds to the deuce mode (S48).

As shown in FIG. 6, the score display unit 200 checks whether there is a difference of two or more points between the seat score and the score of the right side whenever the score signal is received from the score measuring unit 100 (S48, S50, S52). The game continues to receive the score signal from the score measuring unit 100 until the seating face score or the score on the right side is different by two or more points. If the seat score or the score on the right side is different by two points or more, 200) indicates the end of the set game. After several seconds, for example 3 seconds later, the score of both teams is reset.

In the present invention, the determination of the seat surface vibration of the ping pong table and the detection of the right surface vibration may be implemented in various embodiments. In the first embodiment, as shown in FIG. 2, a case where a seating surface, a right side surface, and a net of a table tennis table are connected to each other is used. In a second embodiment, Is spaced at a minimum distance that is not transmitted (a gap that does not interfere with the competition). In the second embodiment, the net is arranged along a spaced space between the left and right sides of the ping-pong table, and both ends of the net are fixed by a support made of heavy metal such as iron.

In the first embodiment, since the seat surface and the right side of the table tennis table and the net are connected to each other, the vibration of the table tennis ball is simultaneously detected on the left side and the right side. It is important to accurately determine in which coat area the vibration is sensed in the present invention in which whether the table pawn court area in which vibration is sensed is the seating face or the right face. Accordingly, in the first embodiment, first, threshold values of vibration values measured by the vibration sensors attached to the seat center and the lower center of the right side of the table tennis table are set. The threshold value is the minimum vibration value that the system recognizes as the vibration of the ping-pong ball. It is a preventive measure to prevent the minute vibration applied to the ping pong due to the movement of the ping pong by hand or the player's movement during the game does not affect the score measurement.

At the start of the game, the seat sensor formed at the center of the seat bottom and the right side sensor located at the center of the bottom of the seat bottom measure the vibration value. The control unit 120 of the score measuring unit 100 compares the vibration value measured by the seat surface sensor and the vibration value measured by the right side surface sensor with a threshold value and determines that the vibration is caused by a table tennis ball, If it is small, it is judged that it is not a vibration caused by a table tennis ball.

When it is determined that the vibration is caused by a table tennis ball, the control unit 120 of the score measuring unit 100 compares the vibration value of the floor surface measured at the same time with the floor vibration value to determine that the vibration value of the floor area . As described above, the score measuring unit 100 according to the first embodiment compares the measured value of the left side sensor with the measured value of the right side sensor every time the vibration exceeding the threshold is sensed, thereby determining the court area of the larger measured value.

In the second embodiment, since the left and right sides of the ping-pong table are spaced apart from each other, vibration generated when the ping-pong ball is applied to the ping pong table is not transmitted to the left and right sides, will be. That is, the vibration on the seat surface and the vibration on the right side can be separately measured.

Therefore, the control unit 120 of the score measuring unit 100 according to the second embodiment performs only a step of checking whether the vibration measurement value of the seat surface sensor and the vibration measurement value of the right side sensor are equal to or greater than a threshold value, There is no need to perform a step of comparing which of the measurement value and the vibration measurement value of the right side sensor is greater.
