Description

Portable Self Scoring Device for Racquet Sports

The present invention relates to a portable self scoring apparatus used for racket sports with a net interposed therebetween.

A scoreboard that records the score is essential for a racket sports game (eg, badminton, ping-pong, etc.) in which a score is scored between the nets and the win or loss is masked. Commonly used scoreboards are handed over the two scorecards, which are officially used on the table and handed over to the table. There is a way. However, such a card-based scoreboard requires management attention due to frequent breaks and loss of score sheets, even though it can be carried, there is an inconvenience in that it is large and heavy.

In addition, since the conventional scorecard type scoreboard must be operated by a third party other than the player, it is not an official competition in which professional athletes participate. In most cases where the referee or scorer cannot proceed, the scoreboard is not available.

In order to score with a referee or recorder, free space must be secured outside the court next to the net.In the case of living sports, several courts can be operated simultaneously. It is difficult to secure safe space for recorders.

Therefore, the game is carried out by calling the scores orally while remembering the scores each time, but when immersed in the game, the players frequently forget or misunderstand the scores, and in severe cases, they argue that they are right. In some cases, this can have an undesired effect on smooth play and performance.

Also, in sports athletics, even if the scoreboard is used for the referee or recorder, if the recorder misoperates sometimes, it must be corrected by someone who informs them of the misoperation. The disadvantage is that it does not fully reflect the score posting characteristics.

As a result, frequent stress on scores by hobbyists has resulted in halving the purpose and effect of sports. In the case of racquet sports, since the score is an important part of the game, there is a need for a desirable way to prevent such fertilization.

In order to solve the above problems, an electronic wireless scoreboard is being proposed in which a player (a sportsman) records a score using a remote controller, but a remote controller has a complicated configuration such as a start, a mode selection, an increase key, a decrease key, and a reset key. Therefore, it is inconvenient for athletes to use the remote control directly during the game. Especially in the case of fast-paced sports such as badminton and table tennis, the operation of the remote controller by the athlete is delayed, and the game flow and game concentration decrease. There is a problem.

Preferably, the first display portion 111 is disposed on the front surface of the scoring apparatus, and the second display portion 121 is disposed on the rear surface or the rear surface of the scoring apparatus.

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 (E-Paper). And FND is preferably used when considering functions.

(3) sensor

The sensor unit 112 is a means for inputting a score of one team, and detects an object (a racket) or a human body within a predetermined range in front of the sensor unit. The sensor unit 112 outputs to the controller a light emitting means for emitting light in a predetermined range, a light receiving means for receiving the reflected light reflected by an object or a human body among the light emitted by the light emitting means, and a detection signal indicating whether or not the light is received. And signal output means. The light emitting means and the light receiving means may be arranged in close proximity or spaced apart from the front portion of the portable self scoring device for racket sports of the present invention. In addition, the sensor unit 112 is, for example, an infrared sensor, infrared transmitting means for transmitting infrared rays of a predetermined wavelength, infrared receiving means for receiving infrared rays reflected by the transmitted infrared rays by an object or a human body, and the presence or absence of infrared rays reception. It may include a signal output means for outputting the detected signal to the control unit. It is also possible to use sound waves in place of the light source in the sensor unit, in which case sound wave transmitting means and sound wave receiving means may be used.

The sensor unit 112 is disposed on the same surface as the first display unit 111, and a range in which a player in competition can recognize a hand, a foot, a racket, etc., preferably within 90 cm in front of the sensor unit, more preferably. Preferably it transmits light or sound waves at an angle of incidence up to 20 °, preferably 10 °, more preferably 5 °, within 70 cm, more preferably within 30 cm, to detect reflected light or sound waves that are reflected and received so that the object or human body Detect it. As a preferred embodiment of the present invention, when the recognition target is an object such as a racket, the sensor recognition distance is preferably within 30 cm in front of the sensor unit, and when the recognition target is a human body, shoes, pants, etc., within 90 cm, more preferably within 70 cm. Is preferably. According to the behavior model test results of the present invention, the recognition distance of the racket by the sensor is set to a maximum 30cm, the distance of 90cm or more, more preferably 70cm or more of the human body, clothes, shoes, etc. is set so that the sensor does not recognize It is preferred (see Fig. 8). As a result, when the athlete in competition unconsciously approaches the apparatus, it is possible to prevent the human body or the athlete's bottom from being scored incorrectly (see FIG. 9). The sensor recognition distance may be adjusted by adjusting the intensity of the light source or sound wave transmitted from the light emitting means or the sound wave transmitting means. Accordingly, the athlete in the game can easily score the goal by extending the hand, foot, racket, etc. within the recognition range at the proper position when scoring. Preferably, when scoring in a badminton game, a handler game, or a ping pong game, the racket may be extended at the service attack position to easily score the goal.

The light emitting means or sound wave transmitting means may be a means commonly used in the art, for example, an LED light source, an IR LED light source, an ultrasonic sensor (transmitter), or the like, and the light receiving means or the sound wave receiving means is conventional in the art. As a means used as, for example, a photo transistor, a photo diode, an ultrasonic sensor (receiver) and the like can be used, but 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 unit, and when an object or a human body exists within the predetermined range, the light or sound waves emitted from the light emitting means or the sound wave transmitting means are the object or the human body. Is reflected by and 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 captured 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 light or sound waves emitted by the light emitting means or the sound wave transmitting means can be determined, for example, by adjusting the intensity, angle, frequency, etc. of the LED light source.

To avoid erroneous scoring due to sensor recognition when the sensor is involuntarily approached, the sensor minimizes the influence of the size of the subject and the reflectivity of the subject's surface. Be aware of it. However, since infrared rays are a kind of light, there is a limit that the recognition distance with respect to the subject may vary according to the size of the subject, the reflectivity of the surface, the angle of the reflecting surface with respect to the sensor, and the like. For example, if a player sets the sensitivity of the sensor based on the distance between the sensor and the racket (a subject with a relatively low reflectance) when the player approaches the device and scores the racket in front of the sensor, The problem of recognizing the leg may occur even for the position of the athlete's leg (a subject having a relatively high reflectance) or even a long distance. This means that if you are involuntarily moving in front of the sensor, even at a distance from the sensor, during the game, the sensor may recognize this and record a score. Accordingly, the present inventors adopt a specific structure for the light receiving means, thereby reducing the difference in recognition distance between a very small object such as a racket and a gut portion of the racket and a large object such as a human body. It was found that it can be minimized. Specifically, in the light-receiving means, the lengthwise shape of the width × length of 0.5 to 2 mm × 2 to 6 mm, more preferably 0.7 to 1 mm × 2 to 4.5 mm, and most preferably 0.7 mm × 2 mm By forming an opening to receive the light reflected through the opening (see Fig. 10), while setting the recognition distance of the racket (object) up to 30 cm without adjusting the intensity of the light source, etc. It was found that a large subject could be recognized only within a distance of 70 cm, so that a subject located at a distance exceeding 70 cm could be set so that the sensor could not recognize it. Therefore, as one of the most preferable embodiment of the sensor part of this invention, the said light receiving means is width x length 0.5-2 mm x 2-6 mm, More preferably, 0.7-1 mm x 3-4.5 mm, Most preferably And receiving a light source reflected through the elongated opening of 0.7 mm x 3 mm. When the light receiving means of the sensor unit has the above structure, the light receiving means and the light emitting means are arranged to be spaced apart from each other by a predetermined distance, and are preferably spaced apart on the same upper and lower lines. FIG. 10 is a view showing an example of a specific structure of the light receiving means. In FIG. 10, a circular broken line virtually shows a light receiving device having a conventional circular structure disposed inside the opening. In the present invention, in addition to the configuration of the above-described sensor unit 112, a sensor generally used in the art such as a motion detection sensor, a proximity sensor may also be used.

(4) control unit

That is, the control unit 201 calculates that the detection signal transmitted from the sensor unit 112 is scored when it lasts for a predetermined time or more. The inventors have found that, through many repeated tests, it is most desirable to add a score if the sensor continuously recognizes an object or human body for 0.7 seconds or more. In order to prevent the player from approaching the scoring apparatus near the scoring apparatus and scoring incorrectly, and to operate the scoring apparatus of the present invention most effectively, the detection signal from the sensor unit 112 is controlled to calculate a score for 0.7 seconds or more. However, it is also possible to set to calculate a score if the duration is longer for more accurate scoring.

Alternatively, the sensor 112 checks whether there is a signal for an object or a human body. When there is a signal in the process, the input signal or the detection signal from the sensor unit is read (step 330).

When there is a signal read in step 330 (step 340), the controller 201 determines whether the input signal is a signal related to a sensor operation pause mode (step 350).

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

When the signal read in step 340 exists and does not satisfy the condition of step 350, it is checked whether the input signal is an input of a score adjustment (+/-) signal (step 360).

When the input signal of step 360 is a positive signal, the controller 201 adds a score to the stored score information by a unit score, and when the input signal is a negative signal, the controller 201 stores the stored score information. The score information is updated to subtract the score by the unit score at step S380. The unit score is usually set to one point, and may be adjusted to the corresponding unit score according to the sport. The updated score information is stored in the memory of the controller, and the controller 201 checks the updated score information and controls to display the updated score information on the first display unit and the second display unit (step 380). The score information updated in operation 380 is stored in a memory of the controller.

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

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

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

The values calculated in the process up to step 390 are backed up and stored in a memory in the controller 201 and are used when signal processing is performed during the same game.

In operation 380, a signal output according to various voice signals, a score recognition signal, a signal indicating a score, and a voice signal indicating a current score may be performed 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 is performed, the process returns to step 330 to repeat the control routine in the same game. The repetitive processing of the control routine is performed until the OFF signal is input by the power button.
