Description

Electronic protector and electronic protector operating system for wireless registration and wireless registration method using the same}

The present invention relates to an electronic protector having a function of automatically detecting an opponent's attack on a player protective equipment used for a martial art game and wirelessly transmitting it to a game operating system. The present invention relates to a method for transmitting information wirelessly to a competition management system and an electronic protector and an electronic protector operating system for implementing the information.

The electronic protector is introduced to protect the athlete's body in martial arts competitions such as taekwondo, and to solve the element of dissatisfaction with the judgment error and the judgment result of the referee due to the fast movement of the athlete. The goal is to use electronic methods to achieve more accurate and fair scoring results. For example, martial arts competitions, such as taekwondo, are generally performed simultaneously on a plurality of courts in a stadium. There are many technical challenges to be solved when attempting to build an electronic protector operating system that is capable of electronic scoring under such conditions.

The existing taekwondo electronic protector incorporates a wireless communication device for transmitting the information about the hit to the scoring processing system, that is, the electronic protector operating system, in addition to the electronic circuit for electronically obtaining the information about the hit. The electronic protector operating system that receives information on the blow from each electronic protector and determines and displays whether or not to score, is also equipped with a wireless communication device. During each match, the electronic protector worn by the players is connected wirelessly to the electronic protector operating system.

Each electronic protector worn by the competitor must be registered in advance in the electronic protector operating system prior to the start of the competition. When a game is played on at least one court, score related information is transmitted from a plurality of electronic protectors. To enable automatic scoring using electronic protector, the electronic protector operating system must have information to identify each electronic protector. In other words, the e-football operating system must know which player wears the electronic protector on which court. If the electronic protective gear worn by the players is not registered in the electronic protective gear operating system before the match starts, the electronic protective gear operating system cannot know whether the received signal is from the electronic protective gear worn by which athlete on which court. Because.

However, the present inventors have found that registering the electronic protector that is actually used or proposed in the computer system (ie, the electronic protector operating system) that operates the tournament is not a simple problem in reality and a problem that cannot be easily solved. In the preliminary rounds of a competition, it is common for multiple games to be played simultaneously on multiple courts. In order to register each electronic protector in the electronic protector operating system, not only the identification information of each electronic protector, but also the information on which athlete is worn by which player and which court is used for the competition, must be provided to the operating system. Just because the electronic protector is in wireless communication with the electronic protector operating system does not allow such information to be registered in the operating system. In practice, the tournament officials must directly identify each player's identification information of the electronic protector he will wear, and register it in the operating system with information about the game and court to be played. For each electronic protector, the necessary setting work must be carried out to enable wireless communication with the operating system. This registration took quite a while and it was difficult to proceed smoothly. In addition, in order to perform these tasks through the wireless communication between the operating system and the wireless communication system, there was also a problem that the interference problem between the coat and the electronic protector must be solved together.

For these reasons, in the past, an electronic protector using a method of registering a connection between an operating system-side receiver and each electronic protector by wire has been proposed, and some of them have been used. However, the wired registration method requires a person to connect the contact point between the operating system receiver and each electronic protector during the registration process, which takes a lot of time, causing problems in smooth competition. For example, if you have to play a lot of competitions from preliminary to final, such as the Olympics or the World Championships, it is common to try to run each race as quickly and efficiently as possible to shorten the overall competition schedule. The existing wireline registration method did not meet this requirement. In addition, the wire protector type electronic protector frequently causes a failure due to contact wear and the like, and thus registration work is often impossible or causes an error. This is one of the reasons why electronic protectors are not yet used in official competitions.

In addition, existing electronic protectors transmit scoring-related information through wireless communication after registration, but have limitations that cannot be applied in large competitions in which several matches are simultaneously held on multiple courts. Because the existing electronic protector uses a specific frequency of radio between the wireless communication unit of the electronic protector and the wireless communication unit of the electronic protector, the channel value is set in advance and the channel value is the same. This is because there is a limit to cross-channel interference or channel allocation when a match is played simultaneously on multiple courts.

Furthermore, since the electronic protector used in some parts uses a sensor for distinguishing the effective blow due to the contact of the switch, sensing can be performed only when the contact of the switch is made by the correct blow. In the electronic protector using the sensor of the switch contact type, there is a problem that the reliability is poor because the sensor frequently reacts due to sweat or moisture contamination.

The most important thing in the function of the electronic protector is to accurately score the opponent's attack. The function of judging the effectiveness of the hit according to the scoring criteria and scoring the score accurately is the most important. The existing electronic protector unit does not sufficiently satisfy such a requirement. For example, according to the currently applied taekwondo game scoring standards, fist attacks are only valid when they hit the part of the body, and existing electronic protectors do not have the ability to make such fine judgments.

Due to the above problems and shortages, the existing electronic protectors are inaccurately judged, causing a lot of complaints from players and officials, and becoming an obstacle to the popularization of electronic protectors. The present inventors came to realize the following technical problems while recognizing the problems of the prior art as described above.

Although not shown in the drawing, the wireless communication units 74 and 84 also have an internal memory in themselves, and a unique ID (for example, a device ID such as a MAC address) is stored in the memory. The unique IDs of the wireless communication units 74 and 84 can also be utilized as identification information for pairing described later. Of course, separate identification information may be given to each electronic protector unit 40 and stored in the memories 78 and 88 and used as identification information for paring. The ADC / DAC may be provided in the wireless communication unit 74 instead of the control unit 72. The memories 78 and 88 also store a program and the like necessary for the operation of the controllers 72 and 82.

 In the operating radio communication unit 70, the radio communication unit 74 has a specific frequency such as 2.4 GHz or 900 MHz, which is set in advance as a carrier wave, and has a structure for modulating and demodulating and transmitting data to be transmitted and received at this frequency. When the wireless communication unit 74 transmits and receives data, the wireless communication unit 74 receives data information to be transmitted from the control unit 72, that is, the microcomputer, modulates the radio signal (RF signal), and then modulates the modulated RF signal to the power amplifier 76. to provide. The modulated RF signal is amplified by the power amplifier 76 to a predetermined intensity and transmitted to the air as an analog radio signal through the antenna 77. The controller 72 may adjust the output strength TX power of the RF signal by adjusting the gain of the power amplifier 76. On the contrary, when receiving data, the wireless communication unit 74 demodulates the RF signal received from the antenna 77 and transmits the demodulated signal to the control unit 72. When the wireless communication unit 74 includes an ADC, the demodulated analog signal is converted into digital data and provided to the control unit 72. In the same manner as described above, the hogu-side radio communication unit 80 performs the transmission and reception of the RF signal.

3 (a) shows the effective signal transmission ranges of the radio signals of the operation side radio communication unit 70 and the protection unit radio communication unit 80 when the radio transmission power of the protection unit radio communication units 80 is set low at the time of registration. Indicates. The operating side wireless communication unit 70 is installed at a position slightly away from the edge of a specific court 90 and the operating side wireless communication unit 80 mounted on each of the electronic protector units 40 worn by the two contestants is operated. This is a case of paring to the side radio communication device 70. 4 is a flowchart for explaining the operation of the registration process between the operating wireless communication device 70 and the hogu-side wireless communication device 80. With reference to these drawings, the procedure of paring before the start of a match with the operating-side radio | communicator 80 mounted on the electronic sideball player 40 worn by the athletes on the operation-side radio | communicator 70 is demonstrated. Here, pairing (paring) is a task to set only the communication port side radio communication unit 80 and the designated operating radio communication unit 70 mounted on the designated electronic protector unit 40 can communicate with each other. The operating side wireless communication unit 70 and the protector side wireless communication unit 80 is configured to be unable to communicate with each other without being registered with each other.

The players' standings will be decided before the match starts. The lottery information includes names, competition courts and corners (blue and red corners) for each player, and information about the opponents of each stage. This lottery information is stored in the computer system 30 in advance. In this situation, when each player wears an electronic protector unit and wants to compete, the information (matching information between the player and the electronic protector unit) for each player wears the electronic protector unit. need. In addition, paring should also be made between the radio communication unit 80 and the operating radio communication unit 70 of the electronic protector unit worn by the contestant. The operation of acquiring the matching information and the registration work between the operation side and the protector side radio communication apparatuses 70 and 80 are performed by the athletes wearing the electronic protector unit 40 on the court at once. 'First registration method' may be obtained, or the operation of acquiring the matching information is first performed by using the registration terminal 220 in the waiting room of the player, and then the operation and protection equipment wireless communication devices 70 and 80. The registration operation of the liver may be a manner in which athletes come up on the court to proceed (hereinafter, referred to as a 'second registration method').

Hereinafter, first, a case according to the first registration method will be described as an example. First, the operation in the operating side wireless communication device 70 will be described. When power is turned on (operation S2) of the operating side wireless communication unit 70, the operating side wireless communication unit 70 configures a wireless network space having an effective communication range of a predetermined radius R3 (step S4). In consideration of the size of the court where the competition takes place, the wireless space is preferably configured as a personal area network (PAN) space. For example, the PAN space configures at least one channel in units of a predetermined frequency (0.0026 GHz), and assigns a plurality of PAN IDs in each channel. In order to form a wireless PAN space, it is preferable that the hog-side radio communicator 80 and the operating-side radio communicator 70 use, for example, Zigbee wireless communication. Of course, other wireless communication methods such as Bluetooth communication, UWB communication, Z-Wave communication or IrDA communication may be used.

The operating wireless communication unit 70 first activates the registration permission mode in the state where the wireless network space is formed. The activation of the registration permission mode is performed when the registration permission button or the reset button is pressed, or when an event such as power supply is given, and the activation state is maintained only for a preset time. The radius R3 of the large circle indicated by the dotted line in FIG. 3 (a) represents the effective communication range of the wireless network space formed by the operating wireless communication device 70.

Then, it waits for the registration request signal from the wireless communication side 80. When the radio registration request signal is transmitted from the call-side radio communication unit (step P12), the operating radio communication unit 70 receives the radio registration request signal and sets a reference value (Link Quality) value of the received signal in advance. N) Check whether or not abnormal (step S8). In this case, the radio wave intensity value means the strength of the signal received from the operating-side radio communication device 70 from the callout-side radio communication device 80, that is, the reception sensitivity. The closer the guard radio to the operating radio, the greater the radio wave strength between the two. Therefore, this value can be used to check the distance and communication quality between the two. For example, the reference value N may be 60 or more, preferably 80 or more, based on the case where the reception sensitivity is divided into steps from the minimum reception sensitivity 0 to the maximum reception sensitivity 255. Of course, the reference value (N) of the radio wave intensity may vary depending on the output strengths of the operating side and the arcuate side wireless communication devices 70 and 80.

When the radio wave strength of the received signal is equal to or greater than the reference value N, that is, when the quality of the received signal exceeds a predetermined standard, the registration permission signal is transmitted as a response signal to the corresponding call-side radio communication unit (step S10). This response signal means that registration is allowed.

Then, when the operating side radio communication unit 70 transmits its identification information, the receiving side radio communication unit 80 receives it, stores it in its own memory 78 and registers it (step S12), and identifies its own unique identity. The information is transmitted to the callout side wireless communication unit 80 (step S14). At this time, the information on the scoring criteria such as the effective scoring strength, the scoring discrimination criteria is also provided. In operation S14, the identification information transmitted from the operating wireless communication device 70 to the caller-side wireless communication device 80 may be a device ID (eg, a MAC address) of the operating wireless communication device 70. The operating side wireless communication device 70 and the protector side wireless communication device 80 can communicate by using the device ID such as the MAC address as identification information of the counterpart. However, since the MAC address is relatively large information of 8 bytes, it is more efficient to communicate with smaller sized identification information. In consideration of this point, the operating radio 70 and the firing-side radio 80 prepare their own network IDs (i.e. nicknames for their MAC addresses) that can be distinguished even by 1 byte. Send to the other party with MAC address. In that case, the ho-gu side radio communication unit 80 and the operation side radio communication unit 70 communicate while identifying each other using this network ID.

Athletes participating in a specific court in the above manner to register (paring) the radio communication unit 80 of their electronic protector unit 40 to the operating radio communication unit (70). However, if the players of the Qing Hong Yang corner follow the registration procedure arbitrarily without following the order, the operating radiocommunicator 70 may not know which corner player each of the hogu radiocommunications requesting registration is. . In order to enable the operating side radio 70 to distinguish between the radio communication unit 80 of the electronic protector unit of the blue corner player and the radio communication unit 80 of the electronic protector unit of the red corner player, the protector side radio communication unit 80. Registration work proceeds sequentially by corner. For example, the referee may instruct the Blue Corner player to proceed with the registration process of the electronic protector unit first, and when the Blue Corner player is registered, the Red Corner player may proceed with the registration process.

When it is confirmed that the operating radio communication unit 70 has registered all of the radio communication unit 80 of the electronic protector unit of the blue and white corner players in this process (paring) (S16) step). As a result, the registration operation for the operating side wireless communication unit 70 of the hori-side wireless communication units 80 is completed.

When a predetermined time elapses from the time when the registration button is pressed or when the registration permission mode is activated, activation of the registration permission mode may be canceled and further registration may not be allowed. This is to prevent the radios that go through the registration process from continuously occupying the radio space without restriction.

Next, the operation in the hogu-side radio communication device 80 will be described. The athletes wear the electronic protective gear unit 40 and approach within a predetermined distance from the operating side wireless communication unit 70, and then turn on the power of the wireless side wireless communication unit 80 (Ho side) wireless communication unit 80 Is supplied with power, and the athlete or the race operator instructs registration by pressing the registration button provided in the user interface 89 (step P2).

When the registration is instructed, the control unit 82 applies an output control signal to the power amplifier 86 to set the amplification ratio low in order to lower the TX power of the protector-side radio communication unit 80 (step P4). ). It is necessary to set the radio signal transmitted by the horseshoe-side radio to be operated in a specific court so low that it does not reach the other undesired operating radios in the surroundings, that is, the operating radios operated in the other court. According to the experiment, it was confirmed that the strength of the wireless output signal of the wireless communication unit on the Hugu side should be about -10 dBm or less in the case of Taekwondo match. With the low amplification ratio set thereafter, the output signal of the power amplifier 86 is amplified at a lower amplification ratio than when it is actually playing and is provided to the antenna 87. In FIG. 3 (a), two small circles indicated by dashed lines, each having a radius R1 and R2, of the volleyball side radio communicator 80 mounted on the electronic volleyball unit 40 of both players with such a low amplification ratio set. The effective communication range of the RF signal is shown. For registration, the two athletes move closer to the operating radiocommunication 70 so that the operating radiocommunication 70 is located within the effective signal range of the RF signal of their respective hoist radiocommunication 80.

Then, the radio network configured in the specific radio frequency band, that is, the radio network (PAN space) formed by the operating radio communication unit 70 is scanned all to detect the existence of the wireless network (step P6). The horseshoe-side wireless communication device 80 may detect a wireless network by scanning a channel and finding a PAN ID for each channel of the wireless network. If a wireless network is detected, the wireless network is a wireless network that allows wireless registration, that is, the operation permitting mode is activated in the operating wireless communication device 70 constituting the detected wireless network (step P8). Find a wireless space having a link quality value of (N) or more (step P10).

If a wireless space that satisfies such conditions is found, the call-side radio communication unit 80 transmits a radio registration request signal to the operation-side radio communication unit 70 constituting the radio space (step P12). When the registration request response signal is received from the operating side wireless communication device 70, the call-side wireless communication device 80 transmits its own identification information, that is, a device ID (eg, a MAC address), to the operating side wireless communication device. (70) (step P14). At this time, if the electronic protector identification number necessary for matching the player with the electronic protector unit 40 he wears is different from the device ID of the protector-side radio communication device, the electronic protector identification number is also transmitted.

After that, upon receiving the unique identification information from the operating-side wireless communication device 70, the ho-gu wireless communication device 80 stores the identification information in its memory 88 and registers it (step P16). 82 provides an amplification ratio control signal to the power amplifier 86 to set the wireless transmission power TX power that was set low for registration to a high value (step P18). The value of the radio transmission output which is set high is effective from the radio side signal of the athlete's horseshoe-side radio communicator 80 which is in charge of the court regardless of the position of the athlete in competition. It should be able to communicate properly. As confirmed by the output experiment, it is desirable to adjust the intensity of the output of the horseshoe-side radio signal over -4dBm during the race. This completes the registration operation in the hogu-side radio communication device 80.

The identification information of the ho-gu side radio communication unit 80 permitting registration by the operating radio communication unit 70 is transmitted to the computer system 30 to share the information. Therefore, the registration subject of the operating side can be seen as the operating side wireless communication device 70 and the computer system 30. The operating wireless communication device 70 merely serves as a relay for supporting wireless communication with the wireless communication device 80 on the fireball side with respect to the computer system 30, and the actual control of the registration procedure is also performed by the computer system 30. It is possible. In any case, the registration information of the protector-side radio communication unit 80 is provided to the computer system 30. The computer system 30 registers the identification information of the horseshoe-side wireless communication device 80 with the personal information of the athlete and registers it in the memory. Then, when the score-related information is received from the electronic protector unit 40 of each player as the game progresses through the operating side wireless communication unit 70, the identification information and the player information of the registered protection unit wireless communication unit 80 are compared. By doing so, the score-related information for each player can be summarized.

3 (b) shows the effective communication range of the output radio signal of each of the hoist-side radio communicators 80 when the radio transmission output of the protector-side radio communicators 80 is set to a high value. In the figure, two circles indicated by dots having radii R4 and R5, respectively, indicate the effective communication range of the horseshoe-side radio communicator 80 mounted on the electronic protector unit 40 worn by the players. Wherever the athletes are on the court 90 during the match, the operating side radio 70 is located within the effective communication range of each side of the wireless communication 80, each side of the wireless communication 80 is operated Normal communication with the side wireless communication unit 70 is possible.

Of course, when the call-side radio communication unit 80 requests radio registration for the operation-side radio communication unit 70 (step P12), it may also transmit its own unique identification information (ID) sent in step P14. Similarly, when the operating radio communication unit 70 returns the registration permission signal (step S10), it may also send its own unique identification information (or even network ID) sent in step S14.

In this way, by registering the protector-side radio transmitters 80 mounted on the electronic protector unit 40 worn by the players in the operating radiocommunicator 70 before the game starts, the operating radiocommunicator 70 after such registration. The wireless communication devices 80 on the side and the other side may distinguish the registered wireless communication device from the wireless communication device that are not using the registered counterpart's unique identification information (ID) or network ID, thereby enabling communication without error between the devices. . That is, after registration, the operation-side radio communication unit 70 can receive only the hitting-related information transmitted by the registered call-side radio communication unit 80 without the influence of other call-side radio communication.

Next, the second registration method will be described. First, the matching operation of the identification information of the athlete and the electronic protector unit is performed in the athlete waiting room using the registration wireless terminal 220. For this purpose, a separate unique identification number can be assigned to each electronic protector unit instead of the device ID. In this case, the computer system 30 has information for matching the unique identification number of the electronic protector unit 40 with the device ID (MAC address) of the radio communication unit 80 mounted on the electronic protector unit 40. It must be stored in advance. The competition agent reads the unique identification number of the electronic protector unit by using the identification information reading unit of the registration wireless terminal 220. The unique identification number of the electronic protector unit read by the identification information reading unit is transmitted to the control unit, and the control unit matches the identification number with the player information according to the substitution table and is transmitted to the computer system 30 through the wireless communication unit. The computer system 30 organizes and stores which player wears the electronic protector unit 40 based on the received information. When the matching operation between the players and the electronic protector unit is completed in the waiting room, the athletes go out to the court and register the wireless communicator 80 of their electronic protector unit 40 with the operating radio of the court 70. This is done by paring.

This registration procedure is almost the same as the first registration method described above. For example, as described above, the control of the wireless communication unit 80 and the registration wireless terminal 220 of the electronic protector unit 40 at the time of registration to lower the intensity of the radio power of at least one or both. However, since the computer system 30 has already secured information on which courts each player participated in which color of the court and which electronic protector unit was worn, the registration procedure here is simply the wireless communication unit 80 of the protector side. ) Has the meaning of pairing the communication with the operating radio (80). Therefore, two athletes in the Blue / Hong corner may register the registration simultaneously without registering sequentially. That is, the operating side wireless communication unit 80 may cancel the registration activation mode when a predetermined number of the protector side wireless communication units 80 are registered.

According to the wireless registration method of the present invention, when a caller-side radio is to be registered to a specific operating-side radio, the caller-side wireless communication device does not reach the other undesired operation-side wireless communication device. This is important because it controls the transmission power of the radio signal to a low degree. If the radio sending power of the hoist-side radio is not set so low, the signal sent by the hoist-side radio, for example, the registration request signal, will be simultaneously received by several operating radios around. At that time, if a plurality of operating radios in charge of different courts have been in a state of enabling the registration allowance mode, the call-side wireless communication device is simultaneously registered with the plurality of operating radios. This is equivalent to the result that the radio communication unit of the electronic protector unit of the athlete who competed in the first court (competition field) is registered in the operating radio communication unit in charge of the second court (competition field). As a result, when viewed from the operating side of the second coat of the wireless communication, the undesirable outcome of the game progress information of the first coat is not received.

Radios of electronic protective gear units worn by athletes on a specific court shall be registered only on the operating radio for the court. When the wireless side wireless transmitter outputs its own radio transmission power at the registration stage, it is within the effective communication range of the low wireless transmission power that it transmits, i.e., the operating side wireless communication apparatus arranged on the same court as the wireless side wireless communication output. (Communication of the operating side radios in charge of each court shall be located within such coverage) and may not be registered with the operating radios in charge of the other courts. By registering in this way, one operating radio for each court is the same as forming a unique wireless network with the hogu-side radio registered to it, and even if several games are played simultaneously in several courts, each wireless network for each court Can operate independently without affecting each other.

The present invention utilizes a link quality value of a wireless space formed by an operating side wireless communication device. By doing so, it is possible to supplement the registration of the call-side radio with the operating radio to which it is registered. In addition, the operating wireless communication unit limits the time for activating the registration allowance mode within a predetermined time. It is to free the processing of the registration request from the operation side wireless communication during the actual competition after the registration by not receiving a registration request from the wireless device on the outside of the registration allowance time.

Contrary to the above method, it is also possible to proceed with the registration procedure by adjusting the transmit power of the operating radio to a low level. That is, by adjusting the transmission power of the operating radio set in a specific court low so as not to affect other courts in the vicinity, it is also possible to register only the hori-side radios trying to register in the court. In addition, it is also possible to perform a registration procedure by adjusting both the transmission powers of the operating radio and the firing-side radio.

For reference, it is difficult to scan and register the protector-side wireless communication device 80 in the operating wireless communication device 70. Since the operating radio is responsible for creating a wireless space, when a request for registration is received from the wireless communication side, the wireless communication side responds to the request. The wireless communication side scans the wireless space and creates the wireless space. Registration is made by requesting registration to the communicator.

2. Detection of scoring-related information and wireless communication method during competition

5 is a conceptual view schematically showing the overall configuration of the Taekwondo game electronic protector unit 40 and the electronic protector operation system 10 according to the present invention taking the case that the Taekwondo game is played on two courts as an example. FIG. 6 is a diagram illustrating a state in which a player wears the electronic protector unit 40, and more specifically describes each component of the electronic protector unit 40. Fig. 7 is a block diagram showing the configuration of the electronic protector unit 40 related to the impact strength detection, the determination of the attack means (fist and foot), and the wireless communication. 8 is a cross-sectional view showing the configuration of the pressure sensor. Hereinafter, the configurations of the electronic protector unit 40 and the electronic protector operating system 10 will be described with reference to these drawings.

It includes a game management server 34 to manage the storage. The headquarters operating computer 36 includes a list of competitors, personal information of each athlete, information on a player who has completed registration on the operating side wireless communication device 70 and his electronic protector unit 40, and matching information therebetween, and During the game, score related information of each player provided from each game operating computer 32 is stored. Application programs are provided for processing such as receiving, storing, managing, and displaying the data on the electronic display panel 20. The display board 20 is connected to the headquarters operating computer 36 to display the progress of the competition and each game, such as the progress of the competition provided by the headquarters operating computer 36 and the score of the ongoing game, on a large screen.

The operating side radio 70 is arranged near the courts 90a and 90b. The game management computer 32 is wirelessly or wiredly connected to the operating wireless communication device 70, and data communication is also possible to the headquarters operating computer 36. The operating side wireless communication device 70 is a computer system for the head protection device 50 and the body protection device 60 of the electronic protection equipment unit 40 through wireless communication with the protection equipment wireless communication device 80 mounted on the electronic protection equipment unit 40. It is to be registered at (30), and receives information about the progress of the game proceeding in each court and transmits to the computer system (30).

The game management computer 32 stores the lottery information provided by the headquarters operating computer 36, the names of the players to be played, the weight, and the like, and identifies the electronic protector unit 40 of the registered volleyball side wireless communication device 80. Received from the operating side wireless communication device 70 and stored separately for each athlete, the result data according to the game operation is also stored. Various data necessary for game operation such as scoring criteria and score calculation logic are stored. In addition, the identification information of each electronic protector unit (that is, the body protector 60 and the head protector 50) is registered for each athlete, and score related information that is transmitted from each electronic protector unit 40 during the game, namely, Effective scores are calculated for each athlete by extracting identification information and effective hits of the electronic protector unit.

This effective score calculation function is provided to the electronic protector unit 40, so that the game operating computer 32 may receive the scoring result as the score related information. To this end, the ho-gu wireless communication unit 80 is configured to receive information related to the game operation from the operating radio communication unit 70 at the time of registration. This information may vary depending on the application implementation, but includes information on reference strength, validity determination criteria, scoring criteria for validity hits, and the like. In this case, the control unit 82 of the horseshoe-side radio communication unit 80 stores this information in the memory 88, and if the information is utilized during the game, it is effective from the detection signals of the tag reader 124 and the pressure sensor 130. You can judge whether you score.

 The information obtained in the course of running the game is transmitted to the headquarters operating computer 36. In some cases, the determination of whether a valid hit is made may be performed by the headquarters operating computer 36. The game management computer 32 is provided with applications for processing required for the competition of such a court.

In an actual implementation, a wireless communication device, such as a wireless access point, may be installed on each court and combined with the competition management computer 32 to form the operating side wireless communication device 70 of the court. Alternatively, the operating side wireless communication device 70 may be configured by embedding the wireless communication device in the game management computer 32. In addition, the configuration of the operating-side wireless communication device 70 may vary.

Next, the structure of the electronic protector unit 40 is demonstrated. Taekwondo electronic protector unit 40 is largely head protection 50, torso 60, gloves 62 and shoes (or socks or foot bands, also referred to as `` racing '') 104 (Hereinafter, the term electronic protector unit 40 means a configuration that includes the headguard 50 and the torso 60, respectively, or both, sometimes with gloves 62 and shoes. It means the configuration including up to 64). Athletes in each of the courts 90a and 90b wear head protection 50 and torso 60 on their heads and torso, respectively, and gloves 62 and shoes 64 on their hands and feet. Wear each. The electronic protector unit 40 is usually made of two colors, blue and red, to distinguish the competition participants by color. The protector side radio communication unit 80 is mounted to the head protection device 50 and the body protection device 60, respectively.

An electronic tag (RFID tag) 125 is embedded in the glove 62 and the shoe 64. The electronic tag 125 includes a chip 127 and a coil 126. The chip 127 has unique tag information embedded therein. Using this electronic tag 125, it is possible to distinguish the type of attack means (whether it is a foot or a fist) of the opponent when the opponent is hit. Coil 126 is preferably installed in the form of surrounding the area facing the front when the fist is pressed forward with the fist (see Fig. 6 (d)), in the case of sports shoes 64 Is preferably installed in such a way that all parts of the foot are covered, such as the instep, heel, sole (see FIG. 6 (e)). The chip 127 is preferably disposed at a location where the impact force is weak at the time of hitting (back of the hand or wrist of the hand, ankle heel of the foot, etc.). In order to have durability, the electronic tag 125 is installed by covering the inside of the shell with a cushioning material.

Each of the head protector 50 and the body protector 60 is a pressure sensor unit for detecting the strength of the blow applied by the opponent and converting it into an electric signal, and a tag reader for determining the approach of the opponent's attack means (fist and foot). Provide a blow information detection unit such as a wealth. In addition, a wireless communication unit for wirelessly transmitting the information on the hit strength and the attack means to the operating wireless communication unit 70, a user interface unit for providing an interface to the user, and an application program required to perform the method according to the present invention Also prepare.

Body protector 60 generally includes a body 66 including a cushioning material such as a shell and an inner skin and a sponge filled therebetween, and a shoulder strap and a strap connected to the body 66 so that the body 66 can be worn on the body. Has a means 68. Head protector 50 is composed of a main body 52 designed to cover both sides of the head and face and a fastening portion 54 connected to the end of the main body. The main body 52 is filled with a cushioning material for shock buffer between the outer shell and the inner shell. For example, when the electronic protector identification number 110 for matching between the player and the electronic protector unit 40 is displayed as a barcode, the identification number barcode may be displayed on the outer surface of the main body 52.

The tag reader unit is for detecting the approach of the electronic tag 125 embedded in the glove 62 or the shoe 64 of the opponent. The tag reader unit includes a tag reader 124 that reads tag information of the electronic tag 125 from an access sensing antenna 120 and a signal transmitted from the antenna 120, and between the antenna 120 and the tag reader 124. It is connected to the matching portion 122 to match the impedance between them. The antenna 120 for access sensing is built along the edge of the main body 52 in the case of the head protector 50 (see FIG. 6B), and in the case of the body protector 60, the entire body portion is wound. It is built in such a way that it can be seen (see FIG. 6 (c)). The access sensing antenna 120 may be made by, for example, winding a thin wire or a coil. In order to prevent damage by hitting, it is preferable to protect the antenna 120 by surrounding the buffer means. Approach detection antenna 120 may detect the distance within which the electronic tag 125 is about 5 cm.

The pressure sensor unit includes a pressure sensor 130 for outputting an electric signal corresponding to the strength of the strike applied by the counterpart, that is, the applied pressure, and a signal amplifier 138 for amplifying the output signal of the pressure sensor 130. The pressure sensor 130 is preferably installed to cover the entire effective hitting area. The pressure sensor 130 is built in the case of the head protection device 50 between the inner skin and the outer skin over the entire body 52 (see FIG. 6 (b)), and in the case of the trunk guard 60, effective blow It is embedded between the main body endothelial and the outer skin throughout the body, which is an area (see FIG. 6C). At this time, by applying an impact protection sponge on the pressure sensor 130 to enhance the durability.

 Background Art A technique for measuring pressure and converting it into an electrical signal is known in the art. The present invention uses a unique film-type pressure sensor 130 configured to be evenly distributed throughout the effective strike portion of the body. 8 is a cross-sectional view for explaining the configuration of the film-type pressure sensor 130 according to the present invention. The film pressure sensor 130 has a structure in which a plurality of bubbles 134 are densely packed inside the thin plastic film 132, and the thin electrodes 136 are bonded to both surfaces of the film 132. When a high voltage is applied to the plastic film 132 for a predetermined time and then removed, the inner surface of each bubble 134 is charged with a specific excess charge. The pressure sensor 130 may be insulated with an insulating film to prevent natural discharge of charged charges.

When the voltage is measured by the voltage meter 137 on the thin electrode 136 in a state in which no pressure is applied to the pressure sensor 130 from the outside, a predetermined voltage V1 is applied to both electrodes 136 due to the charging charge. Appears. When a strike is applied to a specific portion of the pressure sensor 130 from the outside, the bubbles 134 distributed in the strike portion cause a geometrical deformation of the inner space, such as being thinly crushed by the pressure caused by the strike. As a result, a change occurs in the distribution of the electrostatic charges charged in the respective bubbles 134. Accordingly, a change in the charge distribution occurs on both surfaces of the plastic film 132 in contact with the positive electrode 136. There is also a slight change in the voltage that appears. The minute voltage change outputs a linear potential difference with respect to the pressure change applied to the pressure sensor 130. Therefore, the magnitude of the pressure applied to the pressure sensor 130, that is, the strength of the impact by measuring the output voltage (V2) of the film-type pressure sensor 130 when the impact is applied to calculate the magnitude difference with the initial voltage (V1) Able to know. Since the film-type pressure sensor 130 has a myriad of bubbles are formed over the entire surface, it is possible to accurately measure the pressure regardless of the impact position.

The arrangement of the pressure sensor 130 may be changed to suit the scoring standard. According to the Taekwondo scoring criteria, a fist is only scored when hitting a certain area centered on the name. Therefore, in order to determine whether the fist strikes effective strikes to provide a separate pressure sensor to cover the nominal area and the rest of the body. That is, the pressure sensor is provided with a pressure sensor (130b) of approximately circular to cover the nominal area and a pressure sensor (130a) to cover the remaining area of the body except the nominal area to the nominal area and the remaining area of the main body of the electronic protector unit. Built in separately. In addition, the detection signals output from the pressure sensors 130a and 130b in each area are provided to the CPU of the controller 82 by performing signal amplification and analog-digital signal conversion on separate channels, respectively (FIG. f)).

When the pressure sensor unit is configured in this way, the impact strength information provided by the pressure sensor 130b in the bright area is combined with the tag information of the glove 62 that can determine whether the opponent's attack means is a fist. The blow can be determined. Naturally, the effective strike of the foot attack may be determined by combining the tag information of the two pressure sensors 130a and 130b and the shoe shoe 64.

The configuration of the radio transmitter is the same as that of the radio communicators 70 and 80 described in connection with the registration procedure between the radio communicators 70 and 80. The tag reader unit and the pressure sensor unit are combined with the wireless communication unit, that is, the above-described hogu-side radio communicator 80 to constitute the hogu-side radio communicator. Specifically, the tag reader 124 and the signal amplifier 138 are connected to the control unit 82 of the protector side radio communication unit 80. In addition to the registration or power button 144, the control unit 82 is further connected to display means such as a lamp (for example, LED) 142 and a buzzer 143. Also included is a power supply unit 150 for providing the power required for each component of the wireless communication side. The button 144 is used to register the hogu-side radio communication unit 80 with the computer system 30 through the operation-side radio communication unit 70. The LED 142 and the buzzer 143 are for outputting light and sound when an opponent hits the attack. In addition, the LED 142 and the buzzer 143 indicate a power supply shortage condition of the power supply unit or indicate a failure state of the electronic protector unit 40 such as a short circuit of the connection line of the antenna 120 or the pressure sensor 130. Can be used for purposes.

The electronic protector unit 40 preferably has a function of determining whether or not there is an abnormality in itself. For example, a failure such as a short circuit between the antenna 120 and the pressure sensor 130 or a situation such as a low battery level may occur during a game. In this way, if any part of the electronic protector unit 40 fails or is detected while the game is in progress and the game is still in progress, score determination cannot be performed normally, resulting in a large error and confusion of the game itself. Can be. Therefore, for example, a separate logic for checking occurrence of a failure such as a short circuit between the antenna 120 and the pressure sensor 130 and a low battery level is further provided in the controller 82 or a short circuit check unit 160 is additionally provided. When the failure occurs, it is preferable to configure the control unit 82 to notify the failure. When the occurrence of the failure is confirmed, the control unit 82 controls the LED 142 and the buzzer 143 to emit light or an alarm sound, and at the same time, the operation state via the wireless communication unit 84 through the failure state information. Notifies the radio 70. Then, the game progression side may stop the game for a while, so that the failed electronic protector unit 40 may be replaced with a normal one or repaired, and then the action may be continued.

Among the components of the wireless communication unit 80, the pressure sensor 130, the access sensing antenna 120, and the other circuit elements except for the LED 142, buzzer 143, button 144 is one board It is integrated in the form of a circuit module 140. The circuit module 140 is located at a safe position of the torso 60 and the head protector 50, for example, in the case of the torso 60, on the back or shoulder, and in the case of the head protector 50, the back of the head or under the chin. It is preferable to embed in the site.

In the body protector 60 (the same as the head protector 50), when the power is turned on (it is a state after registration), the tag reader 124 uses the power supplied from the power supply unit 150 to match the matching unit 122. Through the drive current flows to the antenna 120 for access detection. Accordingly, the magnetic field is formed over the front of the access sensing antenna 120, that is, the front body protector 60. When the opponent's glove 62 or the shoe 64 approaches the approach sensing antenna 120 within the detectable distance of the tag reader 124 (for example, 5 cm), it is mounted on the glove 62 or the shoe 64. Induced voltage is generated in the coil 126 of the electronic tag 125 by electro-magnetic induction. The induced voltage functions as a power source for driving the chip 127 in the electronic tag 125, so that the chip 127 reads unique tag information stored in the internal memory and radiates it as a radio signal through the coil 126. do. The tag reader 124 receives and reads through the antenna 120 and the matching unit 122 a radio signal containing the thus radiated tag information. The tag information thus read is provided to the controller 82.

When a strike is applied to the body protector 60, the pressure sensor 130 also outputs a detection signal (current corresponding to the voltage or potential difference) corresponding to the intensity of the strike. The output signal is amplified by the signal amplifier 138 and provided to the controller 82. The output signal is converted into a digital signal by the ADC of the controller 82.

The control unit 82 provides the tag information and the hitting strength information provided from the tag reader 124 and the pressure sensor 130 to the wireless communication unit 84 to control the radio information to be transmitted to the operating side wireless communication unit 70. The computer system 30 receives the information through the operating wireless communication unit 70 and performs the scoring process. If the scoring function is assigned to the protector side radio communication unit 80, the operation is performed by the control unit 82, and the scoring result is sent to the operating side radio communication unit 70.

In relation to the scoring process, the electronic tag 125 embedded in the glove 62 and the shoe shoe 64 has different tag information, so that it is an attack of the opponent's fist from the tag information read by the tag reader 124 or not. It is possible to distinguish whether it is a foot attack. In addition, the hitting strength information may be used to determine whether the corresponding hitting strength is greater than or equal to the reference value. Combining these two pieces of information also makes it possible to determine whether the blow was hit by the correct attack site.

The computer system 30 executes a program capable of making these judgments, analyzes the score-related information received through the operating side wireless communication device 70 of each court, determines whether it is a valid blow to recognize the score, Follow the process of assigning a score. If it is determined that it is a valid stroke, the determination result is transmitted to the electronic display panel 20 to be displayed. At the same time, the LED is transmitted to the wireless communication unit 80, the LED (143) and the buzzer 144 to operate for a predetermined time. In the case where the scoring is performed by the protector side wireless communication unit 80, the control unit 82 controls the scoring result to be transmitted wirelessly through the wireless communication unit 84, and the computer system 30 controls the scoring result. Registered in conjunction with and controls the display to be delivered to the display board 20.

When the wireless communication device on the side of the protector 80 wirelessly transmits the scoring result or the tag information and the hitting strength information (hereinafter referred to as valid hitting information), it transmits at a higher output as mentioned above. To this end, the control unit 82 controls the amplification ratio of the power amplifier 86 so that the wireless transmission output becomes a high value after the completion of registration. If the amplification ratio control signal is provided to the power amplifier 86 while providing the effective stroke information to the wireless communication unit 84, the modulated signal carrying the effective stroke information output from the wireless communication unit 84 is amplified to a high output by the power amplifier 86. It is sent out through the antenna 87. During the race it is advisable to adjust the intensity of the radio signal to -4 dBm or more.

FIG. 9 is a view showing an example of a wireless space in which two courts are arranged adjacent to each other in a stadium, registration is performed in one court, and a game is in progress in another court (combined with FIGS. 3A and 3B). One drawing). In the case of taekwondo, the stadium is currently using a square stadium with a width of 10m. Since the wireless side communication device 80a of the two electronic protector units 40a of the first stadium 90a is in the registration stage, the intensity of the radio power is low (-10 dBm or less) and the effective communication range is a radius R1 (or R2). It is narrow so that it does not reach the operating side wireless communication device 70b of the other stadium 90b. Therefore, the protector-side radio communication unit 80a of the two electronic protector units 40a of the first stadium 90a is registered only in the operating-side radio communication unit 70a of the stadium 90a. However, in the second stadium (90b), since the race is in progress after registration is registered, the strength of the radio power of the wireless communication unit 80b of the protector side of the two electronic protector unit 40b is high (-4 dBm or more) effective effective range is a radius Wider to R4 (or R5) (where R4 (or R5)> R1 (or R2)), as well as the first stadium 90a in some cases, as well as the radio side 70b of the operating side of the second stadium 90b; It may even extend to the operating side of the radio (70a). However, unless the registration request signal is transmitted by the wireless communication device 80b of the second stadium 90b, the wireless communication device 80b of the second stadium 90b is an operating wireless communication device of the first stadium 90a. The registration at 70a does not occur.

The registered wireless communication device 70 and the wireless communication device 80 of the electronic protector unit 40 form a separate wireless personal area network (PAN) so that only they have a valid communication relationship. do. Both sides of the radio communication unit 70 and 80 are configured to communicate effectively with each other's identification number, and the other party's identification number is secured only after registration, so that there is a valid communication relationship between the radio communication units having no registration relationship. It cannot be established. Therefore, the wireless communication unit 70b and the electronic protector unit 40b of the specific coat 90b that have undergone the registration procedure have a communication method for a wireless communication device that is operated in another court 90a even though the wireless output strength is high. It does not have a bad effect such as mistransmission of information. That is, the interference between the stadiums and the wireless communication devices does not occur by utilizing the registration relationship.
