The present invention relates to a martial arts impact display device and a display method, and more particularly, to accurately detect a fine vibration using a piezo film according to the strength and position of an impact caused by a price during a martial arts game, and to signal the data. The present invention relates to an impact indicator for martial arts, which can be judged by the referee or the race operator and the audience through visual or auditory judgment to make a fair and accurate judgment.

In general, in martial arts competitions such as taekwondo, various kicking techniques can be used to score points determined by the opponent's body accurately and with strong force. To protect their injuries from these prices, they wear helmets and upper body guards.

The usual way to give a fair score in these sporting events is to give the referee a score after seeing the right kick and hitting technique to see the strong impact on the opponent. Although there are strict rules and regulations for managing competitions, this scoring method has a number of problems:

1. Observing strong shocks is subjective, and this is relative and unequal. Often this scoring method also confuses players and spectators. Since scores based on impact strength and location vary from game to game, it depends on how the judge applies the rules during the same game.

2. The referee's judgment may not be accurate and deterministic because of the limited visibility of the referee's position or speed of movement.

3. The strength of the strong impact varies according to the weight of the athletes and the age group. Therefore, the scoring must be discriminated accordingly. However, since the criteria for evaluation are not constant, the scoring is difficult and the score cannot be constant.

4. The referee cannot sense the intensity of the impacts caused by the price of the athletes, which can cause serious injuries during the match and it is difficult to judge the seriousness of the injury.

In order to improve the above-mentioned problems, a martial arts impact display device has been known, which can help the judgment of the referee by electrically sensing a shock due to a price.

Scoring data corresponding to the scored reference data value selected from among score data of a plurality of digital pulse types inputted in advance in comparison with the scoring reference data values of a plurality of stages previously inputted in stages A score data output step 500 for outputting the score data, a wireless transmission step 600 for wirelessly transmitting the score data to the wireless transmitter 35, and a wireless receiver 51 of the wirelessly transmitted score data. The score data display step 700 is received and displayed on the display unit 60 and the score data storage step 800 stores the wirelessly transmitted score data in the storage unit 53 through the controller 50.

In addition, the scoring reference data value and the scoring data in the scoring data output step 500 are preferably set differentially according to the level, weight or age group of the match, and the display in the scoring data display step (S7) is a plurality of It is preferable to visually display by any one of different colors, numerical values, or histograms, or audibly by the type or height of the sound.

Referring to the operation of the measurement display device and display method for martial arts as described above are as follows.

First, as shown in FIGS. 1 to 4, the piezo film 20 is disposed on the protector 10 as a whole, so that during the martial arts competition such as taekwondo, the effective price portion of the opponent player can be priced by various kick techniques. When the shock due to the price is transmitted to the entire vibration of the piezo film 20 as a fine vibration, the piezo film 20 generates an electric wave in the form of an analog pulse as shown in FIG. 100 (see FIG. 8).

The electric wave appears as a waveform in which the height of the waveform is directly proportional to the intensity and position of the impact. When the waveform is a valid price, the electric wave appears to be high, and it is low due to the movement of the athlete, the contact or press with the opponent, noise, etc. A waveform is formed.

As described above, the minute electric wave in the form of an analog pulse generated from the piezo film 20 is amplified by the amplifier 31 and sent to the A / D converter 32, and the A / D converter 32 does this as shown in FIG. 5B. The amplification step 200 and the A / D conversion step 300 (see FIG. 8) are performed by converting the data signal into a digital pulse form.

Subsequently, the converted data signal is sent to the filter unit 33, and the filter unit 33 removes data signals or various fine noises below the effective price range caused by the movement of the player or the contact or depression of the player. The filtering step 400 is performed, and only the data signal within the valid price range as shown in FIG. 5C is sent to the signal processing controller 34.

As shown in the operation flowchart shown in Fig. 9, the signal processing controller 34 continuously determines whether or not the data signal of the effective price range is input in step S1, and executes the next step S2. In step S2, the scoring data value corresponding to the level of the input data signal is determined by comparing the valid data signal with the scoring reference data values of the plurality of stages set in stages according to the intensity of vibration, and in step S3. The scoring data output step 500 (see FIG. 8) is executed by outputting the scoring data in the form of a digital pulse corresponding to the scoring reference data value.

For example, when the data signal input by the strong effective price among the scoring reference data values set in the A stage, the B stage, and the C stage of the upper stage as shown in FIG. 5D falls within the range of the stage A corresponding to the upper stage, Outputs the scoring data of the highest pulse, and if the data signal inputted by the normal effective price falls within the range of step B corresponding to the middle, outputs the scoring data of the middle height pulse, and inputs the data by the weak valid price. When the signal falls within the range of the lower C stage, the score data of a relatively low pulse is output.

The signal processing controller 34 repeats this operation flow and outputs a corresponding score data signal whenever a new data signal is input.

In addition, the score reference data values of the plurality of stages previously inputted to the signal processing control unit 34 are set to the level of each stage differentially according to the level of the match, the weight and age of the athlete, and the like. By applying the multi-stage scoring standard data value set to the low level for the game of young players and applying the multi-stage scoring standard data set to the high level for the game of high weight class with strong impact strength or adult players, Uniform scoring data can be applied by outputting uniform scoring data regardless of the level, weight and age of the athlete.

As such, the score data output from the signal processing controller 34 is wirelessly transmitted through the wireless transmitter 35 as shown in FIG. 2 to execute the wireless transmission step 600 (see FIG. 8), and the controller 50 Is received by the wireless receiver 51 and sent to the control controller 52, the control controller 52 displays this visually or audiometrically on the display unit 60 to execute the scoring data display step 700 (Fig. 8). In the case of using the display panel as the display unit 60, lamps of different colors are installed on the display panel corresponding to the scoring data set at the upper, middle, and lower levels. For example, the scoring data of the image is red lamp, and the scoring data of the blue is blue. When the score data of the lamp and the bottom are lit by a yellow lamp or displayed on the LCD display or LED display of the electronic display board, the score or height of the bar graph is displayed to visually display the impact of the price step by step, or the controller ( 50) can be displayed audibly by connecting the speaker to the type of sound and display by dividing the type of sound or height.

As a result, the referee or the race operator and the spectator can confirm the intensity of the impact by the visual or auditory display by the display unit 60, and the referee or the race operator can make an accurate and fair decision. In addition, the control and control unit 52 stores the input score data in the storage unit 53 and executes the scoring data storage step 800 (see FIG. 8), so that the analysis data at the time of the objection to the judgment or evaluation of the game later. It can be used as.

In addition, as shown in FIG. 7, according to another embodiment, the piezoelectric films 20A and 20B are disposed in a double manner and connected to the signal processor 30 by the respective cables 21A and 21B made of a conductive material. Even when an abnormality occurs in any one of the piezo films 20A and 20B, the other piezo film 20A or 20B can be compensated to detect an impact, and the strength of the impact is detected by double detection. Comparing the average data with the scoring reference data value enables more accurate measurement.

The scope of the present invention is not limited to the embodiments described so far, and various changes, modifications, or substitutions may be made by those skilled in the art within the technical spirit and claims of the present invention, and such embodiments Should be understood to fall within the scope of the present invention.

As described above, according to the impact display device and display method for martial arts according to the present invention, the intensity according to the position of the impact applied to any of the legitimate target portion during the martial arts game as the overall vibration by the piezo film As it detects, the degree of shock can be accurately measured, only the shock by the correct price is displayed, and the error of the judgment is eliminated, and the validity of the price is displayed step by step so that the judge can make an accurate and fair decision. .

In addition, by applying the effective strength that can be scored by the level, weight and age of the contestant to the multi-stage scoring standard data value, a uniform scoring method can be applied regardless of the level of the match or the weight and age of the athlete. In addition, all valid impact states of the matchers are visually or audibly displayed on the display according to the intensity of the impact, so that the judge or the match operator can make an accurate decision to determine the effective score according to the intensity of the impact.
