Description

The invention relates to an arrangement and a method for electronic detection and processing of racquet sports-related data. The present invention relates generally to the field of electronic capture, processing, and sharing of racquet sports-related data with the aid of connectivity to communications networks. In particular, the invention relates to use in the field of training and / or competition of racquet sports practiced on a playing field with net, e.g. Table tennis, tennis, badminton and the like.

In most racquet sports, especially kickback sports, such as Table tennis, due to the very fast game on the one hand, a very precise learning of the movements for a good game is essential-and on the other hand, a support of the referee by technical measures helpful to resolve controversial decisions in the competition reliably. Currently, table tennis is conventionally practiced and competitively practiced largely without extensive and direct use of the many possibilities of electronic data processing and communication technology. In the field of tennis sports, arrangements and procedures for the electronic collection and processing of racquet sports-related data have already been developed.

So will in DE 20 2010 018 142 U1 discloses a device for improving performance in racquet sports. There, a tennis racket is operatively connected to at least one sensor capable of generating a data signal indicative of at least one parameter associated with the use of the racket, such as the acceleration or pressure of the kickback. A processor processes the data and performs, inter alia, a comparison with historical data for performance recording and evaluation of a player. A feedback system can provide the player with valuable information. In addition, electromechanical components are integrated in the racquet, the characteristics of the racket, such as its stiffness, depending on the data evaluation change. Also, sensors can be integrated in the shoes of the player.

From the DE 90 06 592 U1 An arrangement is known for monitoring, detecting and displaying the touch of the upper edge of a playing field net. The arrangement is used for tennis sports, wherein a plurality of sensors, in particular piezoelectric sensors, are arranged in the vicinity of the central net holder and on the net posts in order to detect and display a contact of the upper net edge. The arrangement also includes a control unit and an evaluation circuit.

The known arrangements and methods are either concerned with a data acquisition directly on the player (rackets, shoes) or with a data acquisition on the field itself (network), which in turn does not allow comprehensive data collection and evaluation of movements in the context of a situation-based performance detection.

It is therefore an object of the present invention to provide an arrangement and a method for the electronic detection and processing of racquet sports-related data, which overcome the disadvantages of the prior art, and in particular for a comprehensive detection and evaluation of motion sequences in the context of a situation-related performance detection are.

The object is achieved by an arrangement having the features of claim 1 and by a method having the features of the independent claim.

Thus, an arrangement and method for electronically detecting and processing racquet sports-related data while practicing a racquet sport on a field by racket is provided, the array having at least one first sensor operably connected to the racquet to provide racquet sports. to collect related data during the practice of racquet sports, and further comprising the arrangement of at least one second sensor operatively connected to the field or components thereof to detect field-related data during the practice of racquet sports.

Thus, at least two different data, namely racket-related data and field-related data are detected by the sensors, whereby a more comprehensive or complex data analysis is possible, which characterizes the entire event in more detail, in particular the behavior of the player on the game / racket and the gameplay on or on the field, including the behavior of the ball played.

Preferably, the respective (second) sensor detecting the field-related data is operatively connected to an area of the playing field and / or a network installed on the playing field, and is particularly integrated therein.

Further, the assembly may include at least one third sensor operatively connected to the player's body to capture body-related data while practicing the racket sport. This sensor may, for example, be functionally connected to a clothing item of the player, such as his shoes, and / or may be connected to a bottom mat designed underneath the player, in particular integrated therein.

The first, second and / or third sensors are preferably connected by means of a wireless communication link to at least one data processing unit, in particular to a mobile communication device (for example smartphone), to a computer (PC, laptop etc.) and / or to a server.

The sensors used may comprise at least one of the following sensor types: piezoelectric sensors and / or photosensitive sensors.

In addition, in a preferred embodiment of the arrangement, at least one data memory (e.g., memory chip or USB stick) is operatively connected to the sensors used and is powered by an accumulator. It can be provided that the arrangement comprises both piezoelectric sensors as well as photosensitive sensors, both of which are also used to charge the battery. In this case, the accumulator can be charged via the piezoelectric sensors in the event of acceleration of the racket and / or pressure of the ball during the setback. Otherwise, the photosensitive sensors (photovoltaic cells) can provide the charging current.

These and other advantageous embodiments will become apparent from the dependent claims.

As will also be apparent from the following description, the approach of the present invention goes far beyond the prior art by detecting and evaluating racket-related and field-related data and possibly adding body-related data. Thereby, e.g. in the field of table tennis, the many ping-peculiarities, such as the use of a racket made of solid material, a table and the usual practice of sports in an indoor environment are included in the process.

The present invention discloses an arrangement and method that allow the exploitation of the capabilities of data acquisition and processing techniques coupled to communications networks. In this way, on the one hand, training can be effectively assisted, e.g. On the other hand, the necessary refereeing decisions at competitions can be made more comprehensibly and correctly in contentious scenes.

The invention is ideally suited for use in training and competition. For example, table tennis is still largely practiced without the direct and immediate use of electronic data processing systems and communication networks to support training or referee decisions. Although there are already highly developed floor coverings and rackets as well as tables, especially in each case in relation to the material used and the processing, but still no sensors and connection to communication networks.

There are already in the field of tennis sports chips that are integrated in the tennis racket. In this case, in the grip of the tennis racket, e.g. An acceleration sensor, a vibration sensor and a gyroscope are located to determine the acceleration, vibration and orientation of the racket. When a button is pressed by the player, the bat collects the data, stores it internally on a memory built into the racket; The data can then be downloaded later via Bluetooth or USB port and further evaluated. Also in the field of football already clothing, which allows parameters such as speed, distance traveled, acceleration, heart rate and performance of the players to capture and read using a corresponding application (short app) on tablet PCs and evaluate. For this purpose, sensors are introduced into the clothing. There is also a football in this context, which can detect, inter alia, trajectory, spin and accuracy electronically sensor-based. However, these known systems capture only specific data in relation to aspects of the tennis or. Football games, these sports are typically held in larger squares (mostly in the open air).

The solution of the present invention goes far beyond the prior art, wherein each of the sports specific features, such as using a table tennis racket made of solid material, a table and the typical exercise of the sport (here eg in an indoor environment) involved in the process can be. In addition, there is the fact that a comprehensive sensor system can be used, which detects, for example, the exact impact position of the ball both on the racket and on the table tennis table. Furthermore, the data does not have to be stored exclusively in the racket, but can also be sent directly via radio communication networks to a central Data acquisition and processing system to be sent.

The present invention is designed to significantly improve the prior art described above so as to allow a very accurate detection of the movements of the athlete (e.g., the table tennis player) and sports equipment (e.g., ball landing positions on the table and movement of the racquet). These data can be used on the one hand to improve the performance of the athlete in training and on the other hand (for example by detecting the impact position of the ball on the table and possible net touches of the ball) in support of referee decisions in competitive situations.

The invention will now be described in detail by means of exemplary embodiments (in the table tennis field) and with reference to the accompanying drawings, which reproduce the following schematic representations:

1 illustrates the use of various sensors in a first embodiment;

2 shows for this first embodiment, the structure of an inventive arrangement;

3 shows for a second embodiment, the structure of an alternative arrangement according to the invention;

4 illustrates the use of the invention for training purposes;

5 illustrates the use of the invention for competitive purposes; and

6 gives a schematic flow diagram for a method according to the invention again.

The 1 and 2 refer to a first embodiment in which data is collected and evaluated during a table tennis game. For this purpose, the arrangement SYS comprises a plurality of sensors, namely at least one first sensor 101 which gathers and delivers bat-related data, this sensor 101 in the racket R of the player P is installed. This is realized, for example, in that the racket R in the covering on both sides with a mat of miniature sensors 101 is equipped, which can determine the impact position of the ball on the racket R sufficiently accurate. In addition, a memory module and possibly a battery, for example, in the grip of the racket R, integrated.

The sensor mats should be designed so that they do not adversely affect the kickback characteristics of the racket. Also, the possibly additional weight of the racket R should be perceived by the player P barely. Also the table T, thus the actual playing field with the table tennis, becomes with a mat or a foil of sensors 102 equipped and mounted on the same, so as not to interfere with the game, but to determine the position of impact of the ball with sufficient accuracy. Furthermore, the network N with sensors 103 equipped so that network contacts of the ball can be determined beyond doubt. In addition, in the shoes S of the player P also a sensor 104 be integrated, which allows to detect foot positions.

About the use of a single pressure sensor in the racket, table and on the net, the application of the invention by the use of one or more sensor mats M on the floor F is clearly out. In one embodiment, in particular for training purposes, the hall floor F surrounding the table T can be equipped with one or more sensor mats (transportable or permanently integrated) in order to detect and record the movements of the player or the two players (see also FIG 4 ).

As far as possible, all recorded data is transmitted to a mobile device (eg smartphone or tablet) using suitable radio technology RF (eg Bluetooth, WLAN) and stored and processed in an application (app) 3 ). In addition, a connection to a server SRV can be established via the communication network, on which the data can be stored, processed and archived in a structured manner in a suitable form. The data processing includes the interaction of all collected data, which are necessary for the evaluation of the performance level of the player. If only a subset of data is required for individual tasks, such as the support of referee decisions (here, for example, the hit position of the ball on the table and the information about the network touch), then only this subset can be extracted and processed.

After the following, the embodiments illustrated in the figures will be described in more detail:
Based on 1 and 2 the mode of action of the invention can be explained particularly well:
On the side of the player P, a sensor mat or foil is applied on both sides of the racket R below the covering (this can possibly be produced in 3D printing). As sensors 101 Piezo sensors can be used, which allow an evaluation of the pressure or pulse and thus the impact position of the ball on the Make the bat and the impact strength detectable. Gyro sensors can also be used - either as part of the sensor mat or integrated as a sensor in the racket handle - to determine the orientation of the racket R in the room or the acceleration can. These (first) sensors 101 thus capture the position of the impact of the ball on the racket R, the impact strength, the club position and orientation in space and movement parameters (eg acceleration, speed). The acquired data are then transmitted by means of a suitable radio technology RF (eg Bluetooth or related technologies such as WLAN) to a preferably mobile device MD, eg a mobile device, a smartphone or a tablet PC (s. 2 ). Alternatively or additionally, the acquired data can be temporarily stored in a (optionally integrated) memory device (eg in the grip of the racket). The transmission of these data can also be done directly to a suitably equipped computer PC (see also 3 showing such an embodiment). There they are prepared by an application and can be used directly, eg in training or competition.

So it is also possible, the data in one embodiment (s. 3 ) directly to a computer PC and / or local server with a corresponding radio module, if the use of individual mobile devices is not desirable (eg in competition situation). In addition, these data are transferred - from the MD mobile device or the tournament computer PC or local server - via a network connection to a remote server SRV in a data center, which stores, processes, processes and archives them.

With local storage of the data in the racket R, the required energy can also be provided by a battery or an accumulator, which can also be located in the club grip. In addition, the energy released by the impact of the ball on the racket R can be converted into electrical energy by suitable transducer elements (e.g., piezo elements) to provide electrical operating energy. With soft coverings anyway a part of the energy is "lost", this could be used to supply the sensors. Also conceivable are photocells, which provide the required energy from the ambient light. This can also be done in a hybrid mode: The accumulator or the battery supports with its energy whenever no energy is available by the impact of the ball or the light output.

Also, the table T itself can be equipped with a sensor mat or foil: This (second) sensor 102 is carried out so that the impact position of the ball can be determined exactly. This has two benefits: First, the sensors can be used in the competition for referee support and decision-making, whether the ball has hit properly. Second, it can be used to optimize training in terms of helping the trainer and the athlete to improve movement and accuracy of play.

In addition, suitable (third) sensors 104 (eg piezoelectric sensors) are also mounted in shoes or their soles: It can thus motion patterns are detected and any systematic movement errors are detected. These data may also be temporarily stored in a storage medium integrated in the shoe, transmitted to a mobile device (eg smartphone, tablet PC) via an aforementioned suitable radio technology, and from there this data is also transmitted via a network connection to a server in a data center. that stores, processes, processes and archives them.

Alternatively or additionally, in a further embodiment variant, a covering equipped with sensors can be designed around the table tennis table T (see Mats 105A1 - 105A4 and 105b1 - 105B4 in 4 ). These mats can be embedded in the hall floor or in the form of mobile sensor mats. This device is used to record the routes and thus the training support and game optimization. The data thus acquired are either cached directly or possibly in a storage medium integrated in the mat, transmitted via a suitable radio technology to a mobile device (eg smartphone, tablet PC) and from there this data also becomes a server via a network connection in a data center that stores, processes, processes and archives them (see also 2 and 3 ).

In particular, the referee support in competition can also the network N and especially the network edge with sensors 103 be equipped to detect a net contact of the ball can. The 1 shows an example of an arrangement according to the embodiment of the invention presented here.

If possible, all information from the racket sensors 101 , Table sensors 102 and network sensors 103 as well as shoe sensors 104 and mat sensors 105 are suitably prepared in the app (lication) of the mobile device or to a greater extent on the server: Statistics are created where the player stands, where the ball hits the bat, which stroke variants are executed (eg forehand, backhand) and where the ball with which Frequency hits on the table, etc. This information is then available via app on the tablet or smartphone or via a web interface. As output devices so preferably mobile devices (eg smartphone, tablet PC) or conventional PCs and laptops are conceivable. For example, the mobile device MD (s. 2 ), which serves to collect the data and the transmission to the server SRV, can also be used as an output device. The user (eg player, coach, referee) can receive statistics on impact positions of the ball on the racket or on the table as well as on legwork via the evaluation of the information. The player (possibly via the trainer) can use this information to improve his batting behavior or his posture and thus use his game as a whole. On the one hand, this information can be interlinked evaluated (eg racket, table and mat / shoe sensors for training optimization) - or they can on the other hand be processed in isolation (eg only table sensors and mesh sensors for referee support) in the competition.

The 1 - 3 illustrate particularly clearly the principle of action or the structure of the arrangement according to the present invention, in particular the interaction of the individual components of the information acquisition and processing. Based on 4 and 5 Two preferred application situations are illustrated. The 6 is a flowchart for the inventive method again.

The 4 refers to an embodiment in which the invention is used in training (training support):
By way of example, two playing fields or tables (SFA, SFB) are set up in a training hall TH. Each player P1-P4 has a racket with (first) sensors 101A1 - 101A2 and 101B1 - 101B2 is equipped to detect racket-related data, in particular hit positions of the ball on the racket surface, pressure or impulse on impact. The (second) sensors record field-related data, in particular ball speed, ball positions on the table tennis table, net touches. These (second) sensors are on the ping-pong table itself as foils 102A respectively. 102B applied or are as network sensors 103A respectively. 103B Installed.

In addition, (third) sensors acquire body-related data, such as positions and movements (direction, speed) of the player. These (third) sensors are in sensor mats 105A1 - 105A4 respectively. 105b1 - 105B4 integrated, which are designed around the respective table or can even be integrated in the floor of the hall. Furthermore, there are (third) sensors 104a1 - 104A2 respectively. 104B1 - 104B2 integrated in the shoes of the players.

As the 4 shows, each playing field according to the principle of the present invention is equipped with such sensors, so that the arrangement or the system can be used for training support. All the above-mentioned data are acquired, stored and processed by the sensors, in particular in a central training computer PCT. Depending on the goal then all data can be used together to improve the overall coordination of movement and hit success of the player or only selected data, eg to improve footwork.

Based on 5 the use of the invention in competition (referee support) is explained:
By way of example, a competition hall WKH with eight tables or playing fields SFA-SFH is shown schematically. The acquisition, evaluation and processing of the sensor data of the respective playing fields SFA-SFH is carried out in the associated pitch-related servers PCTA-PCTH. These give the referees on the sidelines the information they need for their decision plate and network sensors. In addition, a server, here a referee / tournament line computer PCREF is installed directly in the competition hall, to which the information is transmitted in particular from the disk and network sensors: These are for the support of referee decisions of primary interest. The information from the other sensors is more useful for training support (see previous embodiment in FIG 4 ) and can also be transferred to the mobile device in tournament situations as described in the Impact Principle (possibly after the end of the competition), in order to enable a later competition analysis of the player and the trainer.

The 6 illustrates in the form of a flow chart the basic sequence of the method according to the invention 10 for electronic collection and processing of racquet sports-related data. This will be done in one step 11 at least one first sensor operatively connected to the racket (see Sensor 101 in 1 ), Racket-related data is acquired while practicing the racket sport. In a further step 12 are further functionally connected by means of at least one second sensor to the playing field (eg table) or components (eg network) thereof (see Sensors 102 and 103 in 1 ), also includes field-related data while practicing racket sports. In addition, other data, in particular Body-related data (see third sensors 104 and 105 in 1 ) are recorded and evaluated.

The 7 illustrates in the form of a flow chart the basic sequence of another method according to the invention 10 * for electronic collection and processing of racquet sports-related data. This will be done in one step 11 * at least one first sensor operatively connected to the racket (see Sensor 101 in 1 ), Racket-related data is acquired while practicing the racket sport. In further steps 12 * to 1x * are functionally connected by means of at least one second sensor connected to the playing field (eg table) or components (eg net) (see Sensors 102 and 103 in 1 ), also includes field-related data while practicing racket sports. In addition, further data, in particular body-related data (see third sensors 104 and 105 in 1 ) are recorded and evaluated. In this way, additional sensors can be arranged in parallel. These sensor data are transmitted using various transmission techniques (eg Bluetooth, WLAN, ...) in the step 21 * transferred to the data acquisition system (PC, server) and there in step 31 * processed and displayed suitable for evaluation.

• i) Was die verwendete Sensortechnik angeht, so sollen insbesondere die Wahl der Materialen (Matte, Folie) und deren Dimensionierung möglichst so erfolgen, dass sie den Spielverlauf nicht negativ beeinflussen (unerwünschte Dämpfung im Schlägerbelag bzw. auf der Tischtennisplatte usw.). Hinsichtlich der Ausstattung von Tischtennisschlägern mit geeigneter Sensorik, kann gesagt werden, dass die Hersteller von Tischtennisschlägern bereits eine sehr breite Vielfalt von Hölzern (z.T. auch heutzutage aus Carbon) und Belägen (und Kombinationsmöglichkeiten daraus) anbieten. Wenn die erfindungsgemäße Lösung gleich mit bei der Entwicklung von solchen Schlägern und Belägen berücksichtigt würde, könnten mechanische Schlageigenschaften und elektrische Eigenschaften gemeinsam optimiert werden, um das Schlaggefühl des Sportlers nicht zu beeinträchtigen bzw. zu verändern.

In the realization of the invention, among other things, the following considerations are also helpful:

• i) As far as the sensor technology used is concerned, in particular the choice of materials (mat, foil) and their dimensioning should as far as possible be such that they do not adversely affect the course of the game (unwanted damping in the racket surface or on the table tennis table, etc.). With regard to the equipment of table tennis rackets with suitable sensors, it can be said that the manufacturers of table tennis rackets already offer a very wide variety of woods (some today also made of carbon) and coverings (and combinations thereof). If the solution according to the invention were taken into account in the development of such bats and pads, mechanical impact properties and electrical properties could be jointly optimized so as not to adversely affect the athlete's feeling of shock.

• ii) Was die Daten-Verarbeitung bzw. -Auswertung angeht, so wäre insbesondere eine kombinatorische Auswertung der Daten (bezogen auf den Schläger, das Spielfeld und/oder den Spieler/Körper) sinnvoll. Beispielsweise könnte eine gemeinsame Auswertung von der Fußposition (Stellung des Spielers zum Tisch), des Auftreffverhaltens des Balles auf dem Schläger und des Schlagerfolges (über Auftreffpunkt des Balles auf dem Tisch) erhoben werden, um mögliche Fehlerursachen zu erkennen (z.B. der Ball trifft zu weit seitlich auf dem Tisch auf, weil der Spieler bei der(rechtshändigen) Vorhand das rechte – anstatt das linke – Bein vorgestellt hat).
• iii) Des Weiteren kann gesagt werden, dass die Netzwerkstruktur hinter dem Mobilgerät bzw. PC durchaus einem klassischen Betreibernetz entsprechen kann(also dann, wenn das Signal z. B. über das Mobilfunknetz die Gegenstelle (Basisstation) erreicht hat). Die Netzstruktur beim Training kann einfach gehalten werden und besteht nur aus den Signale sendenden Sensoren, dem Mobilgerät und der Verbindung zum Betreibernetz (und darüber zum Server in der Cloud). Beim Wettkampfbetrieb können Rechner im Wettkampfbereich (in der Halle) auch untereinander vernetzt sein, wenn dort mehrere vorhanden sind (dies ist aber für die Erfindung nicht zwingend erforderlich). Die Kommunikation zwischen PCs und Server (im Wettkampfausführungsbeispiel) kann über Funk (WLAN) bzw. mittels Kabel (Ethernet) ausgeführt sein. Zur Datenübertragung können herkömmliche und bekannte Funkübertragungssysteme genutzt werden, z. B. Bluetooth, WLAN, ZigBee, ... Passive Verfahren (z. B. RFID) sind grundsätzlich auch geeignet, haben möglicherweise aber nicht in allen Anwendungsfällen die erforderliche Reichweite, um die Daten ans Verarbeitungssystem (PC, Server) zu übertragen. Zu den Sensortypen zählen auch solche, die die Beschleunigung erfassen können, die die räumliche Lage bestimmen können (Gyro-Sensoren).

It is also conceivable to develop such tables. With the aid of modern production technology, a wide variety of sensors (eg for determining pressure, acceleration, spatial orientation, etc.) can be incorporated / applied in / on different materials.

• ii) As far as the data processing or evaluation is concerned, a combinatorial evaluation of the data (related to the racket, the pitch and / or the player / body) would be particularly useful. For example, a common evaluation of the foot position (position of the player to the table), the impact of the ball on the racket and the hit result (on the point of impact of the ball on the table) could be raised to detect possible causes of error (eg the ball hits too far on the side of the table, because the player in the (right-handed) forehand presented the right - rather than the left leg).
• iii) Furthermore, it can be said that the network structure behind the mobile device or PC can certainly correspond to a classic operator network (ie when the signal has reached the remote station (base station), for example via the mobile radio network). The network structure during training can be kept simple and consists only of the signals sending sensors, the mobile device and the connection to the operator network (and to the server in the cloud). At the Competition mode computers in the competition area (in the hall) can also be networked with each other, if there are several there (but this is not mandatory for the invention). The communication between PCs and servers (in the competition embodiment) can be carried out via radio (WLAN) or by means of cable (Ethernet). For data transmission conventional and known radio transmission systems can be used, for. For example, Bluetooth, WLAN, ZigBee, ... Passive methods (eg RFID) are also suitable in principle, but may not have the necessary range in all applications to transfer the data to the processing system (PC, server). Sensor types also include those that can detect the acceleration that can determine the spatial position (gyro sensors).
