Portable self-scoring device for racket sports

The present invention relates to a self-scoring device for a racket motion in which a net is placed in the middle.

In the middle of the net, in the racket competition (such as badminton, billiards, etc.) obtained by the score to determine the victory or defeat, it is necessary to record the scoreboard of the score. The commonly used scoreboard includes a method of flipping the scoreboards of both parties. The official adopts the method of placing on the table and flipping by hand, as the case may include counting from the neck overhanging the scoreboard, and then including the fixed setting. The way of making iron stands, etc. However, since the card score board frequently breaks and loses the individual scoreboards, it is required to pay attention to management. Even if it is portable, it is inconvenient to carry because of its large size and heavy weight.

In addition, since the scoring board of the individual scoring card type of the conventional method is required to be operated by a third party other than the player, the daily meeting such as the general participation is performed at a formal meeting where the professional player does not participate. In many cases where it is not possible to assign a referee or a score recorder who participates in a third party other than the competitive player, there is a problem that the competitive scoreboard cannot be used.

In order to assign a referee or recorder to score, it must be adjacent to the stadium to ensure The extra space used by the recorder, but in fact, the degree of daily life movement, due to the use of multiple courses at the same time, and the distance between the courses, it is difficult to ensure that all the courses can be played from the smash and other strong protection. The safe space of the recorder.

Therefore, athletes often remember the scores of each other, calculate the scores verbally, and compete on the side. When they are engaged in competition, the athletes forget to forget or misunderstand the scores frequently. They inexplicably claim that they are correct, and may also cause quarrels and smoothness. The competitive progress and athleticism may have adverse effects.

In addition, in sports competitions of daily life, even if a referee or a recorder is assigned, the scoreboard is used. If the recorder occasionally mishandles, if the fact that the other person does not complain about the misoperation, the correction cannot be made, and therefore the motion cannot be fully reflected. And the correct score reveals the shortcomings of the feature.

As above, due to the frequent arguments about the scores, the pressure of the same person accumulates pressure, and as a result, the purpose and effect of daily life are halved. In the case of racket sports, since scores account for an important part of the competition, better countermeasures are sought to prevent such disputes from occurring.

In order to solve such problems, an electronic wireless scoreboard is proposed, in which a player (a person who performs exercise in daily life) records a score using a remote controller, but the remote controller includes a start, a mode selection, a bonus button, a minus button, Reset buttons, etc., constitute a complex, legitimate competition, players (in the daily life of the athletes) difficult to operate the remote control, especially in the fast-moving sports such as badminton, billiards, etc., if the player performs remote control operations, the competition will be delayed And there is a problem that the competitive process is not smooth and the concentration of competition is reduced.

For display devices such as (organic light-emitting diodes) and E-Paper (Electronic Paper), it is preferable to use FNDs for consideration of cost and function.

(3) Sensor section

The sensor portion 112 is a mechanism for inputting a score, and senses an object (racquet) or a person within a certain range in front of the sensor portion 112. The sensor unit 112 is provided with an illuminating mechanism and is distributed in a certain range. The light-receiving mechanism receives the reflected light reflected by the object or the person among the lights emitted by the light-emitting means, and the signal output means outputs a detection signal indicating whether or not the light is received to the control unit. The light-emitting mechanism and the light-receiving mechanism may be disposed adjacent to each other or apart from each other in the portable self-scoring device for racket motion of the present invention. Further, the sensor unit 112 may be an infrared sensor as an example, or may include an infrared transmission unit that transmits infrared rays of a predetermined wavelength, and an infrared reception unit that receives infrared rays that are transmitted by the object or a person by the infrared rays that are transmitted; The signal output unit outputs a detection signal indicating whether or not the infrared light is received to the control unit. In the sensor portion, a sound wave may be used instead of the light source. In this case, a sound wave transmitting mechanism and a sound wave receiving mechanism may be used.

The sensor unit 112 is disposed on the same surface as the first display unit 111, and the range in which the player in the competition is to extend the hand or the foot, the racket, etc., to be recognized is preferably within 90 cm in front, and more preferably Within 70cm, and then preferably within 30cm, and the incident angle should be at most 20°, more preferably 10°, and further preferably 5°, transmitting light or sound waves, sensing the reflected light or sound waves received and reflected, thereby feeling Measure objects or people. As a preferred embodiment of the present invention, when the object to be recognized is an object such as a racket, the sensor identification distance should be within 30 cm of the front of the sensor portion, and the object to be recognized as a character, shoes, pants, etc., should be within 90 cm. Further preferably within 70 cm. According to the test result of the inventor's action mode, the recognition distance of the racket of the sensor should be set to a maximum of 30 cm, and the sensor can not recognize the distance of more than 90 cm, and it is preferable to set a person or clothes that cannot sense the distance of 70 cm or more. , footwear, etc. (Fig. 8). Thereby, when the player in the competition unconsciously approaches the device side, it is possible to prevent the person who is mistakenly recognizing the person or the player's blouse or the like from being scored (refer to FIG. 9). The sensor identification distance can be adjusted by adjusting the intensity of the light source or sound wave emitted from the light-emitting mechanism or the sound wave transmitting mechanism. In this way, when the player in the competition scores, the hand or the foot, the racket, and the like can be extended within the aforementioned recognition range at the appropriate position, and the score is easily scored. Suitable for badminton, table badminton, and table When the ball is scored, the score can be easily scored by extending the racket due to the position of the attack.

The light-emitting mechanism or the sound wave transmitting mechanism is a mechanism generally used in the field, and for example, an LED light source, an IR, an LED light source, an ultrasonic sensor (transmitting portion), or the like may be used, and the light receiving mechanism or the sound wave receiving mechanism is in the field. Generally, a mechanism to be used may be, for example, a photoelectric crystal, a photodiode, an ultrasonic sensor (receiving portion), or the like, but is not limited to such a mechanism.

The illuminating mechanism or the sound wave transmitting mechanism emits light or sound waves to a certain range in front of the sensor. When an object or a person exists within the certain range, the light or sound wave emitted from the illuminating mechanism or the sound wave transmitting mechanism may be the object or person The reflection is received or received by the light receiving mechanism or the sound receiving mechanism. The light receiving means or the sound 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 via the signal output means. The range of light or sound waves emitted by the light-emitting means or the sound wave transmitting means can also be determined by adjusting, for example, the intensity, angle, frequency, and the like of the LED light source.

When the sensor is unconsciously approached, in order to avoid misidentification caused by sensor identification, the influence of the size of the object, the reflectance of the surface of the object, etc. must be minimized, so that the sensor only recognizes a certain distance. The subject is inside. However, since the infrared ray is a kind of light, there is a limit to the recognition distance to the subject due to the size of the subject, the degree of surface reflectance, and the angle to the reflecting surface of the sensor. For example, if the player approaches the device for scoring, the sensor is set to measure the distance between the sensor when the racket is lifted in front of the sensor and the distance of the racket (the object with a relatively low reflectance). The degree is likely to occur at the position of the player's foot (the object with a relatively high reflectance), or a distance above it, and the problem of the foot is also recognized. This means that it is very likely that in the competition, even if it is a distance far from the sensor, when the sensor unconsciously communicates in front of the sensor, the sensor recognizes the error in recording the score. Here, the inventors found that by The light-receiving device is selected to have a specific structure, and the difference in the recognition distance between the object such as the racket and the racket of the racket (the string of the racket), the object that is positively small in the body, and the object that is bulky of the subject is reduced. To a minimum. Specifically, it is found that the light-receiving mechanism is formed to have a horizontal width × a vertical width 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 an elongated opening of 0.7 mm × 2 mm. a light source that is reflected by an object or a person is received by the opening portion (refer to FIG. 10), and the identification distance of the racket (object) is set to a maximum of 30 cm without making adjustment of the light source intensity or the like, and the distance is only within 70 cm. To identify a large-sized subject such as a character, and set the sensor to be unable to recognize an object located at a distance of more than 70 cm. Therefore, as a preferred embodiment of the sensor unit of the present invention, the light receiving means is 0.5 to 2 mm × 2 to 6 mm, more preferably 0.7 to 1 mm × 2 mm. The light source reflected at 4.5 mm, preferably 0.7 mm × 3 mm, is received by the light source. When the light receiving means of the sensor portion has the above-described structure, the light receiving means and the light emitting means are disposed at a predetermined distance, and are preferably disposed apart from each other on the upper and lower lines. Fig. 10 is a view showing an example of a specific structure of the light-receiving mechanism. In Fig. 10, a circular dotted line is a light-receiving device that generally represents a generally circular structure disposed inside the opening. In the present invention, in addition to the configuration of the sensor portion 112 described above, a sensor that is generally used in the field, such as a motion sensing sensor, a proximity sensor, or the like, may be used.

When the condition of the foregoing stage 350 is met, when the previous operation mode is the sensor operation mode, the control unit 201 switches to the sensor operation stop mode, and when the previous operation mode is the sensor operation stop mode, the switch is sensed. Tester action mode (stage 351).

There is a signal loaded from the aforementioned stage 340, and if the condition of the aforementioned stage 350 is not met, it is confirmed whether the input signal is an input of a fractional adjustment (+/-) signal (stage 360).

When the input signal of the preceding stage 360 is a (+) signal, the control unit 201 is based on the saved score information, and adds the score to the unit score. When the input signal is a (-) signal, the control unit 201 links the saved score information to the score. The score information is updated by subtracting the unit score (stage 380). The above unit score is generally set to 1 point, and can also be adjusted to the unit score according to the type of competition. The updated score information is stored in the memory of the control unit, and the control unit 201 confirms the updated score information, and displays the updated score information on the first display unit and the second display unit (stage 380). The score information updated in stage 380 is stored in the memory of the control unit.

Then, if the condition of the foregoing stage 360 is not met, it is confirmed whether the input signal is a detection signal that is sensed by the sensor 112 for a certain period of time or longer (stage 370). When the input signal is the detection signal sensed by the sensor, the control unit 201 controls the lamp output unit 113 to display the sensed detection signal. When the identification detection signal of the object or person in the above stage 370 continues for a certain period of time or longer, the control unit 201 adds the score of the saved score information, adds the unit score, and updates the score information (stage 380). The score information updated in stage 380 is stored in the memory of the control unit.

After the interpretation of the signal input as described above, the signal processing is performed by the counter and the internal computing unit in the control unit 201, and the display control is performed in each operation mode. That is, in the aforementioned scoring device, the signal processing and updating are performed in the aforementioned stage 380. The value is output as a display signal (stage 390).

The aforementioned signal display is displayed by the display device of the portion of the text to be displayed, and the number is preferably displayed via the FND device.

The value calculated in the process executed in the above-described stage 390 is backed up and stored in the memory in the control unit 201, and is used when the signal processing is performed during the same competitive period.

Further, in the stage 380, various sound signals, a score recognition signal, a signal for notifying the score, and a signal output for notifying the sound signal of the current score may be performed via the sound output unit 203. The audio signal outputted through the acoustic output unit 203 is stored in the memory in the control unit 201 in accordance with each operation mode.

After performing the foregoing stage 390, returning to stage 330, the aforementioned control routine is repeated in the same competition. The above-described control routine repeats the processing until the signal is turned OFF by the power button input.
