Description

Non-intrusive wireless sensor system for harvesting and processing physical and technical data of the player, the team and the match in the practice of indoor amateur football.

PURPOSE OF THE INVENTION

Several techniques combining electromagnetic sensors embedded on the players and / or on the ball have been marketed in the past.

All allow to recover only the physical data of players.

However, there are certain wireless techniques, not available to the general public to date, allowing the recovery of physical and technical data of players and team in the practice of football.

With regard to the technical data, they plan to recover all the data coming only from the contacts foot / balloon.

No existing technique, to date, allows the recovery of complete data related to the practice of football and especially indoor football.

In addition to offering only a part of the statistical data, the existing technical solutions are not usable by amateur football players, especially in the classroom, because: - Invasive because of the weight and size of the players. sensors - Binding use protocol because to be reloaded by human intervention. - Costly solution

The sensors of the system (1) use and couple two wireless technologies namely a radio frequency system, advantageously RFID (Radio Frequency IDentification), and BLE (Bluetooth Low Energy) to access all the physical and technical data related to the practice of football and more particularly of indoor football.

The inventive nature of the components and the operation of the system (1), described below, makes it possible to collect all the data (11), (12), (13) and (14) during the practice of indoor football. .

The present invention aims to set up a simple system of installation and use, non-intrusive and low cost allowing the recovery of physical and technical data of players and indoor football teams in the amateur world.

SUMMARY OF THE INVENTION

The rules of indoor football are substantially similar to that of outdoor football.

The main difference is that one-meter high balustrades are present all around the terrain and are an integral part of it.

Thus, rebounds are allowed significantly increasing the time and intensity of the game.

In addition, indoor football pitches are rented by 8 to 10 players for a standard duration of one hour.

There are today more than 150 sports complexes in France, each with several fields. The indoor football market in France and Europe has been growing rapidly since the last five years, as the amateur world now has as many football players outside as in the hall.

In principle, all the events related to the football match are recorded thanks to the interaction between the sensors of the system (1).

These interactions are then coupled to a given time, which will allow to retranscribe the events in their order of realization. The ingenuity of these sensors and the nature and multiplicity of their interactions is at the heart of the innovation and inventiveness of this statement.

The system (1) thus allows the reconstruction of the chronology of events then at the origin of four types of data, recovered within the framework of a football activity and more particularly of indoor football: - Physical and technical data of the player (11) - Goalkeeper specific physical and technical data (12) - Technical data of the football match (13) - Physical and technical data of the team (14)

For such a system (1) to be set up as part of an indoor football practice, it must have the following characteristics: - Easy to install and use, therefore non-intrusive, for the practicing only for the manager of the complex hosting the grounds. - Low cost of embedded sensors, given the number of practitioners. - Group the four types of data mentioned above. - Display this data in real time to allow instant access to statistics for practitioners.

Thus, by its design and operation, the system (1) is particularly suitable for playing indoor football.

The sensor (2) included in the balloon is a radio frequency sensor.

No function of artificial intelligence, information storage, information transfer is planned.

The sensor (2) will only serve to declare its presence to the players include on the player (3) and (4), in the cages and around the field (5). It is called tag.

The communication frequency is between 860 and 960MHz The antenna of this tag is specifically designed to operate unilaterally and at distances adapted to the application.

This is specifically the reading distance with an autonomous reader (3) up to 50 cm with a success rate, in all cases of reading, greater than 97%.

This is specifically the reading distance with a long range reader (5) up to 5.5 m with a success rate, in all cases of reading, greater than 99%.

The sensor (2) is in the form of a label with a thickness of less than 0.5 mm, a length of less than 2 cm and a width of less than 2 cm which can be very simply included on or under the outer layer of the balloon.

It can then be advantageously fixed by thermoactivation of a glue particularly suitable for this type of materials and use.

No development and additional cost is expected to include the sensor (2) in the balloon, unlike known techniques providing for the manufacture of the specific balloon then to accommodate a larger sensor in the center of the latter. The use of the sensor (2) makes possible the use of commercially available balloon.

The sensor (2) in the balloon, being a simple tag and not a transmitter, the problem of non-uniform reading according to the position of the balloon is set. Indeed, the reading being performed by (3), (4) and (5), the latter can be done in all directions of the sensor (2) on the ball.

The sensor in the balloon, being a simple tag and not transmitter, no power supply is required. Thus, no device and protocol is necessary for charging the sensor linked to the balloon.

The reader (3) intelligently fixed under or on the tongue of the player's shoes or shoes is composed of the following elements (7): Radio frequency reader: emission of a field-electromagnetic to measure the presence or absence of the ball nearby . The communication frequency is between 860 and 960MHz

This emission being of short range because the desired reading distance does not exceed 50cm. Play time between (2) and (3) is reduced by the use of a specific player (3) and will record any type of contact related to the practice of indoor football.

Indeed, the reader (3) is designated so as to read the sensor (2) at a distance of less than 50 cm in a short time, of the order of ten ms (milliseconds) - A BLE module to transfer the data to the central unit (4).

Transmitting frequency: 2.4 GHz

A rechargeable wireless power source. This may advantageously be a miniature battery or capacitor.

It can be advantageously recharged thanks to the energy generated from the moving player or by the BLE emission of the central unit (4).

The reader (3) has the sole function of passing the balloon information to the central unit (4). It will therefore be used as an information relay.

For this reason, this miniature and autonomous power source alone will power the radiofrequency reader (3) coupled thereto.

A buffer unit may be embedded, included in the BLE module.

The advantages of this reader (3) are: - No other power supply is required. Thus, no human intervention is necessary for recharging the player (3) linked to the player's tongue.

Advantageously, the system (1) eliminates the risk that the reader (3) is not electrically powered during the game. - No energy storage system with a footprint in weight, size and cost is expected. - There is no mechanical system or physical connector for charging and replacing the power source. - The reader, for its simplicity, is miniaturized and low cost.

The reader (3) will be intelligently attached to the tab, preferably by a system of clips easy to use.

This system, by its operation, allows the fixing and the easy and fast removal of the reader (3) on the tongue.

This fixing system, by its operation, allows the durable attachment of the reader (3) on the tongue during the course of a football match.

The non-intrusive character of the reader (3) on the tongue is therefore put forward by its design and its integration in the player's tongue. The central unit (4) is composed of the following elements (8): Radio frequency reader: emission of an electromagnetic field in order to measure the presence or absence of the balloon in the vicinity. The communication frequency is between 860 and 960MHz

By its interaction with the other components of (1), it will recover all the non-recoverable data by the only communication between the sensor (2) and the reader (3).

In addition, the contacts between the balloon and the body parts, above the pool, may be referenced, an example being the hand / ball contact. - A BLE module to recover data from the reader (3)

This module will also allow the transfer of data to the central (6)

Frequency of emission: 2.4 GHz - An artificial intelligence unit or processor: Specific algorithms will be embedded in the processor.

This processor has the function of managing the BLE communication with the reader (3) and the central console (6).

Its function is to control its integrated radio frequency reader.

Its function is to manage and process data from the reader (3) and the central unit (4). - A memory unit: the data then processed are stored in this unit. - An energy storage unit is required to power the various functions included in the central unit (4). This will be reloaded by induction when stored on the center console (6). It will be sized for minimum operation of a rental day. Inventiveness is based on the fact of centralizing in the central unit (4) all the functions requiring energy, space and adding an overweight.

This central unit included in a bracelet, size and weight similar to a classic watch, will not be an element jeopardizing the ergonomics of the player. Note that an additional bracelet will be used by the guard. It will then be identical to the first and will be included on the other arm. They will retrieve all technical data, physical and events specifically related to goalkeeper (12).

One or more long mounted readers (5) will be disposed outside the field (9) such as

A reader in each cage allowing, when it is calibrated, to account for the fact that the ball has entered this specific area. - One or more readers are installed around the field in order to communicate and to exchange with the reader of the central unit (4). The use of the long-range readers (5) thus makes it possible to recover in real time:

The positioning of each player on the field and the goalkeeper.

The differences in power of reception of the signal, emitted by the central unit (4) and received by the different long range readers, make it possible to determine the position of the central unit (4) and therefore of the player.

This information, linked to a given time, is at the origin of a part of the technical and physical data of the player (11), the goalkeeper (12), the match (13) and therefore the team (14). ).

Technical match events related to the practice of indoor football, such as the referencing of all contacts of the players and the ball with the balustrades. - Real-time reading of the data stored in the central unit (4). The data display can therefore be performed during the game on the screen of the central console (6).

A central console (6) is placed near the football practice area.

It consists of the following elements: - An induction storage and recharging area for the central units. - A BLE reader allowing the recovery of data stored in the memory of the central unit (4). - A computer allowing the processing and communication on the Internet of all data collected. - A screen allowing the display of raw data as well as the profiles of the players.

It will preferably touch to allow interactivity and exchange of information between users and the central console (6).

Thus, the information generated by the different interactions of the system's sensors can be classified as follows (10): o Sensor interaction (2) and reader (3) at the origin of part of the data: - Player's techniques - Goalkeeper techniques * => Sensor interaction (2) and central unit reader (4) at the origin of a part of the data: - Player techniques - Goaltender specific techniques => Sensor interaction (2) and long-range reader (5) at the origin of a part of the data: - Player's techniques - Specific techniques to the goalkeeper - Techniques of the football match => Player interaction (4) and long readers ( 5) at the origin of a part of the data: - Technical and physical of the player - Techniques and physics specific to the goalkeeper - Techniques of the football match

All these interactions are therefore at the origin of the four types of data recovered in the context of a football activity and more particularly of indoor football: - Physical and technical data of the player (11) - Physical and technical data specific to the goalkeeper (12) - Technical data of the indoor football match (13) - Physical and technical data of the team (14), resulting from (11) and (12) and (13). EXEMPLARY EMBODIMENT:

One of the industrial applications is therefore the use of the system (1) in the practice of indoor amateur football. The use of such a system, in this context, can be done as follows (15): - Each player is registered on the center console (6). - It recovers and fixes the reader (3) to his or her shoes. - It recovers and fixed on his wrist the central unit (4) with the help of a bracelet. - Running of the indoor football session with the use of a balloon equipped with the sensor (2) and on a court equipped with one or more long-range readers (5)

During the session, the data is displayed in real time on the screen of the central console (6) - At the end of the session, each player rests the player (s) (3) and the central unit (4). ) in the dedicated area of the center console (6) - The above four data types are then available for display on the center console.

A specific application will be available on the smartphone of the practitioner. The latter may, if he wishes, recover the technical and physical data that are specific to him via the application. It will be enough to transfer the data stored in the central unit (4) in its smartphone via the BLE connectivity.

A personalized profile, created beforehand by the practitioner, will be updated with these new data.

Algorithms, specifically developed, will then allow the development of an individual scoring system (16) updated after each session.

This profile as well as this scoring system may be available for an individual as well as for a team. Other applications will use these profiles, an example being online games.

The wifi connectivity of the central console (6) will allow data retrieval and display of the latter via a dedicated website.
