Description

[0001] PORTABLE SELF-SCORING APPARATUS FOR RACKET SPORTS [0002]

The present invention relates to a portable self-scoring device for use in racquet sports across a net.

A scorecard that records scores is essential for racket sporting events (eg, badminton, table tennis, etc.) in which the winner or loser is scored by obtaining scores across the net. Generally used scoreboards are handed over to both sides of the score card. They are put on the table and handed over by hand. In some cases, the scoreboard is put on the neck and counted. . However, such a card type score board requires careful attention due to frequent breakage and loss of the score sheet, and even though it can be carried, it is large and heavy and inconvenient to carry.

In addition, such conventional score card type scoreboards must be operated by a third party other than the athlete, so it is not an official competition in which professional athletes participate, but in the case of daily sports events in which the general public participates, The disadvantage is that in most cases the referee or scorer will not be able to proceed with the scorecard.

In order to score by putting a referee or a recorder, it is necessary to secure space for the recorder besides the net beside the net. In the case of daily sports, it operates several coats at the same time. Due to the close distance between the coats, It is difficult to secure a secure free space for the recorder.

Therefore, the players will remember the score each time and play the game while singing the score verbally. However, when the players are immersed in the game, they frequently forget the score or mistake the score, There is also the case that this will have an undesirable effect on the smooth progress of the game and the performance.

In addition, even if a scoreboard is used with a referee or a recorder in a sport for athletic athletics, sometimes, if the recorder is erroneously operated, it can be corrected if another person informs the operator of the erroneous operation. It has a disadvantage that it can not sufficiently reflect the score posting characteristic.

As mentioned above, the frequent application of the score to the stressors of the clubs results in a decrease in the purpose and effect of sports. In the case of racquet sports, the score is an important part of the game.

In order to solve the above problem, there has been proposed an electronic wireless scoreboard in which a player (athletic athlete) records a score using a remote controller, but the remote controller is complicated in configuration such as start, mode selection, increase key, Therefore, it is inconvenient for the athlete (athletic athlete) to use the remote controller directly during the game. Especially when the athletic game such as badminton or table tennis is fast, the manipulation of the remote control by the athlete is delayed, . Also, due to the nature of the sweaty game, the remote control can cause discomfort of hygiene problems and possession during the game, and may cause loss of remote control.

The present invention seeks to provide a portable self-scoring device for racket sports which is portable and can score a competition score by a simple operation by a player (a living athletic person).

The display unit may be a display device such as a flexible numeric display (FND), a light emitting diode (LED), a liquid crystal display (LCD), an organic light emitting diode (OLED), and an electronic paper And the FND is preferably used when considering the function.

(3)

The sensor unit 112 is a means for inputting a score of a team, and detects an object (racket) or a human body within a certain range in front of the sensor unit. The sensor unit 112 includes a light emitting unit that emits light in a predetermined range, a light receiving unit that receives reflected light that is reflected by an object or a human body among light emitted by the light emitting unit, and a detection signal that indicates whether or not light is received, And a signal output means for outputting the signal. The light emitting means and the light receiving means may be arranged close to or spaced from each other on the front face of the portable self-scoring apparatus for racket sports according to the present invention. The sensor unit 112 is, for example, an infrared sensor, which includes infrared transmitting means for transmitting infrared rays of a certain wavelength, infrared receiving means for receiving the infrared rays transmitted by the object or the human body, And a signal output means for outputting a detection signal indicating the detected signal to the control unit. It is also possible to use a sound wave in place of the light source in the sensor unit, and in this case, sound wave transmitting means and sound wave receiving means can be used.

The sensor unit 112 is disposed on the same plane as the first display unit 111 and is positioned within a range capable of recognizing a player's hand, foot, racket, or the like, preferably within 90 cm forward of the sensor unit The light or sound wave is transmitted at a maximum angle of incidence of 20 degrees, preferably 10 degrees, more preferably 5 degrees, within 70 cm, more preferably within 30 cm, of the object or human body Lt; / RTI > In a preferred embodiment of the present invention, when the object to be recognized is an object such as a racket or the like, it is preferable that the sensor recognition distance is within 30 cm in front of the sensor portion, and within 90 cm, more preferably within 70 cm . According to the behavioral model test results of the present inventor, the recognition distance of the racket by the sensor is set at a maximum of 30 cm, and the human body, clothes, and shoes having a distance of 90 cm or more, more preferably 70 cm or more, (See Fig. 8). Thereby, it is possible to prevent the player who is in the game from accidentally scoring by recognizing the human body, the lower part of the athlete, etc. when the player unconsciously approaches the apparatus (see FIG. 9). The sensor recognition distance can be adjusted by adjusting the intensity of a light source or a sound wave sent from the light emitting means or the sound wave transmitting means. Accordingly, a running athlete can easily score a score by extending a hand, a foot, or a racket within the recognition range at a proper position at the time of scoring. Preferably, the badminton game, the handler game, and the ping pong game can be easily scored by extending the racket in the service attack position at the time of scoring.

The light emitting means or the sound wave transmitting means may be an LED light source, an IR LED light source, an ultrasonic sensor (transmitting portion), or the like. The light receiving means or the sound wave receiving means may be a conventional means in the art For example, a phototransistor, a photodiode, an ultrasonic sensor (receiver), or the like can be used, but the present invention is not limited thereto.

The light emitting means or the sound wave transmitting means emits light or sound waves in a certain range in front of the sensor portion and light or sound waves emitted from the light emitting means or the sound wave transmitting means in the case where an object or a human body exists within the certain range, And is received or received by the light receiving means or the sound wave receiving means. The light receiving means or the sound wave receiving means converts the reflected light or the reflected sound wave into an electric signal and transmits the detection signal to the control unit 201 through the signal output means. The range of the light or sound wave emitted by the light emitting means or the sound wave transmitting means can be determined, for example, by adjusting the intensity and angle of the LED light source, the frequency, and the like.

In order to avoid false scoring by recognizing the sensor when unconscious approaching the sensor, the influence of the size of the subject and the reflectivity of the subject surface is minimized so that only the subject within a certain distance It should be recognizable. However, since infrared rays are a type of light, there is a limitation that the perceived distance to the subject can be changed depending on the size of the subject, the reflection of the surface, and the angle of the reflection surface with respect to the sensor. For example, when the player sets the degree of sensitivity of the sensor based on the distance between the sensor and the racket (the object having a relatively low reflectance) when the player approaches the device for scoring and puts the racket in front of the sensor, There may arise a problem of recognizing the legs even at the position of the player's legs (the object having a relatively high reflectance) or even at a farther distance therefrom. This means that if the player unconsciously comes to the front of the sensor even at a considerable distance from the sensor during the game, the sensor may recognize the error and record the score. By adopting a specific structure for the light receiving means, the inventor of the present invention has found that by using a specific structure for the light receiving means, it is possible to reduce the difference in the perceived distance between a target having a very small volume of a subject such as a racket or a racket and a target having a large volume such as a human body It can be minimized. Specifically, the light-receiving means has a vertically elongated shape with a width and a width of 0.5 to 2 mm x 2 to 6 mm, more preferably 0.7 to 1 mm x 2 to 4.5 mm, and most preferably 0.7 mm x 2 mm (See FIG. 10), the recognition distance of the racket (object) is set to a maximum of 30 cm without adjusting the intensity of the light source, and at the same time, the volume of the object It has been found that a large subject can be recognized only within a distance of 70 cm, so that objects located at distances greater than 70 cm can be set so that the sensor is not recognized. Therefore, as a most preferred embodiment of the sensor unit of the present invention, the light receiving means has a width and a width of 0.5 to 2 mm x 2 to 6 mm, more preferably 0.7 to 1 mm x 3 to 4.5 mm, And receives the light reflected through the vertically elongated opening of 0.7 mm x 3 mm. When the light-receiving means of the sensor portion has the above structure, the light-receiving means and the light-emitting means are spaced apart from each other by a predetermined distance, and are preferably arranged on the same vertical line. Fig. 10 is a view showing an example of the specific structure of the light receiving means. In Fig. 10, a circular broken line is a virtual imaginary light receiving device of a circular structure disposed inside the opening. In the present invention, in addition to the above-described configuration of the sensor unit 112, a sensor commonly used in the art such as a motion detection sensor and a proximity sensor may be used.

Hereinafter, the operation of the portable self-scoring apparatus for racket sports according to the present invention will be described.

6 is a flowchart of a portable self-scoring apparatus for racket sports according to the present invention.

When the power switch of the portable self-scorching apparatus for racket sports is turned on and the power of the power source unit 202 is supplied, the power of the power source unit 202 is supplied to each circuit element of the inside of the main body 200, Are in a standby state in which they can operate.

The control unit 201 first performs setting (initialization) to an initial state after initial power-on (step 310). After the initial setting, the control unit checks the connection state of each circuit element, and the initial information is stored in the memory inside the control unit 201. The data stored in the memory is read as needed and used for signal processing. The initialized information is displayed on the first display unit 111 and the second display unit 121 (operation 320).

The control unit 201 determines whether a key signal by button selection is inputted through the manual input unit 150. [ Or whether there is a signal for an object or a human body through the sensor unit 112. When the signal is present in the process, the input signal or the detection signal from the sensor unit is read (operation 330).

If there is a signal read in operation 330, the controller 201 determines whether the input signal is a signal related to a sensor operation suspend mode in operation 350.

If the condition of step 350 is satisfied, the controller 201 switches to stop the sensor operation when the previous operation mode is the sensor operation mode and controls the operation to switch to the sensor operation mode when the previous operation mode is the sensor operation stop mode (Step 351).

If the signal read in step 340 is present and the condition of step 350 is not satisfied, it is confirmed whether the input signal is an input of a scoring (+/-) signal (operation 360).

If the input signal in step 360 is a positive signal, the control unit 201 adds the score to the stored score information by a unit score. If the input signal is a negative signal, the control unit 201 stores the stored score information The score information is updated so as to subtract the score from the unit score (Step 380). The unit score is usually set to one point and can be adjusted to the corresponding unit score according to the event. The updated score information is stored in the memory of the control unit, and the control unit 201 checks the updated score information and controls the first display unit and the second display unit to display updated score information (Step 380). The score information updated in operation 380 is stored in the memory of the control unit.

If the condition of step 360 is not satisfied, it is determined whether the detection signal detected by the input signal sensor 112 is greater than a predetermined time (step 370). If the input signal is a detection signal sensed through the sensor, the control unit 201 controls the lamp output unit 113 to indicate that the detection signal is being sensed. If the detection signal of the object or the human body in step 370 continues for 0.7 seconds or more, the controller 201 adds the score to the stored score information by the unit score, and updates the score information (step 380). The score information updated in operation 380 is stored in the memory of the control unit.

After the signal input through the above process is decoded, signal processing is performed through the counter and the internal arithmetic unit in the control unit 201, and display control is performed in each operation mode. That is, the signal processing and updated values in step 380 of the scoring apparatus are output as a display signal (step 390).

The signal display is displayed by the display device of the character portion corresponding to the score to be displayed, and preferably, the corresponding number is displayed through the FND device.

The values calculated in the process up to step 390 are stored in the memory in the control unit 201 and used for signal processing during the same game.

In operation 380, various audio signals, a score recognition signal, a signal indicating a score, and a signal output according to a voice signal indicating a current score can be output through the sound output unit 203. [ The sound signals output through the sound output unit 203 are stored in the memory in the control unit 201 for each operation mode.

After the step 390, the control routine is returned to step 330 and the control routine is repeatedly performed in the same game. The repetitive processing of the control routine is performed until the OFF signal is input by the power button.
