The present application relates to a player tracking device for tracking a player position. Specifically, it relates to a positioning sensor device for positioning a player position.

The positioning sensor device mainly includes a positioning sensor device using an LPS module and a positioning sensor device using a GPS module. The positioning sensor device receives a position signal including position information and uses a method of calculating the position of the positioning sensor device by triangulation.

In addition, in order for the positioning sensor device to receive the position signal including the position information, a radiation pattern for transmitting the position signal may be generated by the feed plate of the antenna. In this case, in order to calculate an accurate position by the positioning sensor device, the direction in which the position signal is transmitted and the radiation pattern (especially the max value of the radiation pattern) generated by the antenna must correspond. In other words, in order to calculate an accurate position by the positioning sensor device, the radiation pattern generated by the positioning sensor device must face a direction in which the position signal is transmitted or be inclined in the direction in which the position signal is transmitted.

However, in order to measure the position of the sports player through the positioning sensor device during a sports game, the sports player must wear the positioning sensor device on a part of the sports player's body. In this case, depending on the worn position, the positioning sensor device may not be able to generate an optimal radiation pattern for receiving the position signal.

Additionally, since a sports player performs various movements such as a sprint operation during a sports game, the direction of the radiation pattern of the receiving surface of the antenna formed from the positioning sensor device worn on the sports player is continuously changed according to the movement.

See FIG. 1 . 1 is an exemplary diagram illustrating a change in the center of gravity of a sports player's body when the athlete stands upright and when the sports athlete performs a sprint motion.

Referring to FIG. 1 , when the sports player 1 is upright, the center of gravity of the sports player's body may be formed in a direction Z substantially perpendicular to the ground. On the other hand, when the sports player 1 performs the sprint motion, the center of gravity of the sports player 1 may be inclined forward. Therefore, when the sports player 1 performs the sprint motion, the center of gravity of the body of the sports player 1 is formed in a direction (C) inclined at a certain angle with respect to a direction (Z) substantially perpendicular to the ground. can Therefore, in order to measure the position of a sports player who plays sports through a positioning sensor device worn on the sports player, the movement of the sports player must be considered.

The player tracking device according to an embodiment disclosed herein may have a structure capable of implementing an optimal radiation pattern of a GPS antenna module in consideration of a direction in which a location signal is transmitted.

In addition, the player tracking apparatus according to an embodiment disclosed herein may include a structure for implementing an optimal radiation pattern of the GPS antenna module in consideration of the sports player's movement as well as the case where the sports player is upright.

Hereinafter, with reference to FIG. 2, the radiation pattern generated by the conventional player tracking device 10 and the accuracy of the obtained position will be described.

2 is a view showing the radiation pattern of the internal components of the conventional player tracking device 10 and the receiving surface of the GPS antenna module 14. As shown in FIG.

Specifically, the conventional player tracking device 10 may include a housing 12 , a GPS antenna module 14 , and a battery 18 .

Referring to FIG. 2 , the radiation pattern of the receiving surface of the GPS antenna module 14 of the conventional athlete tracking device 10 has a relatively weak radiation pattern with respect to the direction in which the position signal is transmitted (eg, above the athlete). This is formed and it can be seen that a relatively strong radiation pattern is formed in the forward direction or the downward direction of the conventional player tracking device 10 .

In addition, the position of the sports player 1 obtained by the position signal received by the conventional player tracking device 10 may be different each time the position of the sports player 1 is obtained, even if they move the same route. Specifically, referring to FIG. 2 , it can be confirmed that the position of the sports player 1 moving on the same path is repeatedly measured a plurality of times and the position of the sports player 1 is different each time. This is because, according to the conventional player tracking device 10, the radiation pattern of the receiving surface of the GPS antenna module 14 is formed relatively weakly with respect to the direction in which the position signal is transmitted, so that the accurate position calculation is not performed.

Hereinafter, with reference to FIG. 3 , in more detail, a radiation pattern generated by the conventional player tracking device 10 and a direction in which a position signal is transmitted will be described.

3 is a schematic diagram illustrating receiving a position signal using the conventional player tracking device 10 .

Specifically, FIG. 3 shows the reception direction of the position signal and the maximum direction of the radiation pattern generated by the athlete tracking device 10 when the sports player 1 is upright. In addition, the receiving direction of the position signal when the sports player 1 performs a running motion and the maximum direction of the radiation pattern generated by the athlete tracking device 10 are shown.

Referring to FIG. 3 , the player tracking device 10 may be worn on a part of the body of the sports player 1 . For example, the player tracking device 10 may be worn on the back of the player 1 .

The player tracking device 10 may receive a position signal.

In this case, the position signal may be a position signal transmitted from a satellite in relation to a global navigation satellite system (GNSS). In this case, since the satellite is far away, it can be assumed that the position signal substantially transmitted from the satellite is transmitted in a direction substantially perpendicular to the ground (Z) and parallel to the direction. Hereinafter, it is assumed that the direction Z' of the position signal transmitted from the satellite comes in a direction Z substantially perpendicular to the ground.

However, this is only an example, and the direction (Z') of the position signal transmitted from the satellite may be a certain angle with respect to the direction (Z) substantially perpendicular to the ground, but even in this case, the upper side of the sports player 1 What is sent from will be the same.

On the other hand, the radiation pattern by the GPS antenna module 14 included in the existing player tracking device 10 may be formed in a direction RP1 inclined toward a direction Y parallel to the ground. Therefore, since the radiation pattern does not relatively correspond to the direction (Z') in which the position signal is transmitted, the position of the player calculated by the transmitted position signal may not be relatively accurate.

In addition, when the sports player 1 performs a sprint motion or a motion of walking fast forward, the athlete tracking device 10 worn on a part of the body of the sports player 1 is upright due to the movement of the athlete Otherwise, the radiation pattern formed by the GPS antenna module 14 is changed.

For example, when the sports player 1 performs a sprint motion, the center of gravity is generally inclined forward. In other words, when the sports player 1 performs the sprint motion, the center of gravity of the body is inclined forward and may be formed in a direction C having a predetermined angle with respect to a direction Z substantially perpendicular to the ground. . Accordingly, the radiation pattern of the receiving surface of the GPS antenna module 14 worn on the back of the sports player 1 may also be changed. For example, the radiation pattern by the receiving surface of the GPS antenna module 14 is closer to the direction (Z') in which the position signal is transmitted, but is still inclined toward the direction (Y) parallel to the ground (RP2). can be formed.

Therefore, since the radiation pattern still does not correspond to the direction (Z') in which the position signal is transmitted, the position of the athlete calculated by the transmitted position signal may not be relatively accurate.

In addition, since the player is analyzed based on the position of the player that is not obtained relatively accurately, the result of analyzing the player by the conventional player tracking device may also be inaccurate.

Hereinafter, the player tracking device 100 for overcoming the limitations of the existing positioning sensor device 10 according to an embodiment of the present specification will be described.

Athlete tracking apparatus 100 according to an embodiment of the present specification may include a reflector to move the radiation pattern by the receiving surface so that the radiation pattern by the receiving surface of the GPS antenna module faces upward through which the location signal is transmitted. .

In addition, in the player tracking device 100 according to another embodiment of the present specification, the player tracking device 100 adjusts the installation angle of the GPS antenna module so that the radiation pattern by the receiving surface of the GPS antenna module transmits the position signal upward. It is possible to move the radiation pattern by the receiving surface to face.

Hereinafter, the positioning sensor device 100 according to the embodiments of the present specification will be described on the assumption that the direction in which the position signal is transmitted is substantially the same as the Z-axis perpendicular to the ground, but this is only an example for convenience of description. , it will be apparent that the technical features of the player tracking apparatus 100 described herein can be applied even when the position signal is transmitted in various directions in the upper direction of the sports player with respect to the ground.

It can be seen that a large value was formed. In particular, since the reflector 160 is included, a part of the electromagnetic wave radiated from the GPS antenna module 140 is reflected toward the Z-axis direction. Therefore, the radiation pattern of the electromagnetic wave radiated from the GPS antenna module 140 is relatively inclined toward the Z-axis direction or is formed to be inclined in the Z-axis direction than when the reflector is not included.

In addition, it can be confirmed that the maximum value (Max) of the radiation pattern of the electromagnetic wave radiated from the GPS antenna module 140 is formed by changing the position from the Y-axis to the Z-axis.

At this time, the Z axis is the direction extending from the other side 124 of the housing of the player tracking device 100 to the one side 122 of the housing, that is, the housing is located in the pocket of the player's clothing according to the embodiment of the present specification. It may mean an upward direction in the inserted state, and the Y axis is a longitudinal section of the housing 120 of the player tracking device 100 according to an embodiment of the present specification, that is, perpendicular to the ventral side of the housing 120 . It can mean one direction.

Accordingly, the player tracking apparatus 100 including the reflector 160 according to an embodiment of the present specification may improve reception sensitivity for a position signal including position information.

Hereinafter, the player tracking device 100 according to another embodiment of the present specification will be described with reference to FIG. 6 . In this case, the contents of the player tracking apparatus 100 according to an embodiment of the present specification described in relation to FIGS. 4 and 5 may be equally applied, and the following will be mainly described with respect to additional contents. In addition, the content of the player tracking device 100 according to an embodiment of the present specification described in relation to FIGS. 4 and 5 and the content of the player tracking device 100 according to another embodiment of the present specification to be described later are combined with each other. can be implemented.

6 is a schematic diagram illustrating a radiation pattern of the player tracking device 100 and the GPS antenna module 140 according to another embodiment of the present application.

The GPS antenna module 140 may have a receiving surface provided in a flat plate shape. The GPS antenna module 140 may receive a location signal such as a GPS signal through the receiving surface.

The receiving surface of the GPS antenna module 140 is inclined at a predetermined angle with respect to at least one circuit board so that the receiving surface faces upward while the housing 120 is inserted into a pocket formed on clothing worn by the player. It can be mounted inside.

In this case, the preset angle may be, for example, within an angle range of greater than 0° and less than 90°. For example, the preset angle may be within an angle range of 5° or more and 45° or less.

Specifically, the player tracking apparatus 100 according to the present embodiment may include at least one circuit board. In this case, the at least one circuit board may include a main circuit board 152 and a sub circuit board 154 .

In this case, the main circuit board 152 may be provided in a flat plate shape. Specifically, the main circuit board 152 has a bottom surface facing the player's back and a top surface opposite to the back in a state in which the housing 120 of the player tracking device 100 is inserted into the pocket. It may be provided in a flat plate shape having two main surfaces including a.

At this time, the main circuit board 152 is installed inside the housing so that the two main surfaces are substantially parallel to the back side of the housing 120 in the state where the housing 120 of the player tracking device 100 is inserted into the pocket. can be

A GPS antenna module 140 or a battery 180 may be installed on the main circuit board 152 . However, according to a preferred embodiment, the battery 180 is installed on the main circuit board 152 , but the GPS antenna module 140 may be installed on the sub circuit board 154 to be described later. In other words, the GPS antenna module 140 and the battery 180 may be installed on different circuit boards.

The sub circuit board 154 may be provided in a flat plate shape similar to the main circuit board 152 . Specifically, the sub circuit board 154 has a bottom surface facing the player's back and a top surface opposite to the back in a state in which the housing 120 of the player tracking device 100 is inserted into the pocket. It may be provided in a flat plate shape having two main surfaces including a.

In addition, the GPS antenna module 140 may be installed on the rear or front surface of the sub circuit board 154 .

In addition, the rear surface, the front surface, or two main surfaces of the sub circuit board 154 may be installed inside the housing so as to be inclined at a predetermined angle with the rear surface of the housing 120 . That is, the sub circuit board 154 may be installed inside the housing so that the rear, front, or two main surfaces of the sub circuit board 154 are inclined at a predetermined angle with respect to the main circuit board 152 .

Accordingly, the receiving surface of the GPS antenna module 140 installed on the sub-circuit board 154 may be provided to face upward while the housing is inserted into the pocket.

Also, the sub circuit board 154 may be mounted in the housing to be positioned above the main circuit board 152 with the housing inserted into the pocket. In other words, the sub circuit board 154 may be mounted in a position closer to the main circuit board 152 than the main circuit board 152 with respect to one side 122 of the housing 120 in a state in which the housing is inserted into the pocket. .

In the player tracking apparatus 100 according to this embodiment, the GPS antenna module 140 installed on the sub circuit board 154 is located adjacent to the direction in which the position signal is transmitted, and the sub circuit board 154 is the main circuit board. As it is configured to be inclined at a predetermined angle with respect to 152 , the receiving surface of the GPS antenna module 140 may be provided to face the direction in which the location signal is transmitted, thereby improving the reception sensitivity for the location signal.

Referring back to FIGS. 2 and 6 , the radiation pattern by the receiving surface of the GPS antenna module 140 of the player tracking device 100 according to the present embodiment is higher than the radiation pattern of the conventional player tracking device 10 , the position It can be seen that a relatively strong radiation pattern is formed with respect to the direction in which the signal is transmitted (eg, above the athlete).

In addition, when the position of the sports player acquired by the position signal received by the player tracking device 100 according to the present embodiment moves the same path repeatedly a plurality of times, the reproducibility and accuracy of the acquired position are similar to those of the prior art. It can be seen that it is significantly improved compared to the player tracking device 10 of This is, in the player tracking device 100 according to this embodiment, the sub circuit board 154 is inclined at a certain angle with respect to the main circuit board 152 so that the receiving surface of the GPS antenna module 140 faces upward. This is because, due to the true configuration, the radiation pattern by the receiving surface of the GPS antenna module 140 is strongly formed with respect to the direction in which the position signal is transmitted.

In addition, by additionally providing the reflector 160 described above in relation to FIGS. 4 and 5, a portion of the electromagnetic wave radiated by the feed plate 142 of the GPS antenna module 140 is reflected to form a radiation pattern, the position signal is Since it can be formed to face the transmission direction or to be inclined in the direction in which the location signal is transmitted, it is possible to further improve the reception sensitivity of the GPS signal.

Hereinafter, the relationship between the GPS antenna module 140 and the reflector 160 of the player tracking apparatus 100 according to the present embodiment will be described in detail with reference to FIG. 7 .

7 is a cross-sectional view showing the internal components of the player tracking device 100 according to the present embodiment.

Referring to FIG. 7 , the player tracking apparatus 100 according to the present embodiment may include a plurality of circuit boards. Specifically, the player tracking device 100 may include a main circuit board 152 on which the battery 180 is installed and a sub circuit board 154 on which the GPS antenna module 140 is installed.

At this time, in the sub circuit board 154 on which the GPS antenna module 140 is installed, the main circuit board 152 on which the battery 180 is installed while the housing is inserted into the pocket formed on the clothing worn by the player. It may be configured to be positioned on the inside of the housing with respect to the. Accordingly, the GPS antenna module 140 may be disposed adjacent to the upper direction in which the location signal is transmitted, so that the reception sensitivity of the GPS antenna module 140 may be improved.

Also, as described above, the sub circuit board 154 on which the GPS antenna module 140 is installed may be installed in the housing by being inclined at a predetermined angle with respect to the main circuit board 152 . Accordingly, the receiving surface of the GPS antenna module 140 installed on the sub-circuit board 154 may also face upwards through which the location signal is transmitted while the housing is inserted into the pocket formed on the clothing worn by the player. , the reception sensitivity of the GPS antenna module 140 may be improved.

In addition, as described above, the reflector 160 located on the battery 180 reflects some electromagnetic waves, thereby moving the radiation pattern of the receiving surface of the GPS antenna module 140 upward. Accordingly, the reception sensitivity of the GPS antenna module 140 may be further improved. 7 shows that the reflector 160 is installed on the battery 180, but this is only an example, and as described above, located below the GPS antenna module 140 in the front area of the sub circuit board 154. The reflector 160 may be installed in the region, or the reflector 160 may be installed in the front region of the main circuit board 152 positioned between the GPS antenna module 140 and the battery 180 .

At this time, the reflector 160 may perform a function of improving the reception sensitivity of the GPS antenna module 140 by reflecting the electromagnetic wave radiated from the GPS antenna module 140 and the position signal in the form of an electromagnetic wave transmitted from the satellite. .

In addition, in order to further improve the reception sensitivity of the GPS antenna module 140 , the position of the GPS antenna module 140 is located adjacent to the rear surface 126 of the housing 120 relative to the position of the reflector 160 . As much as possible, the GPS antenna module 140 may be mounted in the housing.

Specifically, in order for the reflector 160 to reflect some electromagnetic waves and move the radiation pattern of the receiving surface of the GPS antenna module 140 upward to form it, the reflector 160 more easily reflects some electromagnetic waves. may be requested

For example, it may be preferable that the reflector 160 is spaced apart from the rear surface 126 of the housing rather than the receiving surface of the GPS antenna module 140 . Referring back to FIG. 7 , the central region C1 of the receiving surface of the GPS antenna module 140 may be provided to be adjacent to the rear surface 126 of the housing rather than the central region C2 of the reflector 160 to be described later. On the other hand, the central region C2 of the reflector 160 may be provided to be spaced apart from the rear surface 126 of the housing rather than the central region C1 of the receiving surface.

The player tracking device 100 according to the present embodiment is provided with the above-described structure, so that it can be provided to more easily reflect the position signal transmitted from the upper direction to be received by the receiving surface of the GPS antenna module 140 . . In addition, reflection of some electromagnetic waves radiated from the GPS antenna module 140 becomes easier, so that the radiation pattern of the receiving surface can also be moved in the upward direction through which the position signal is transmitted.

However, the above description is only an example, and even if the reflector 160 is located relatively adjacent to the rear surface 126 of the housing rather than the receiving surface of the GPS antenna module 140, the reflector 160 facilitates reflection of electromagnetic waves. It will be apparent that it may be provided in any suitable principle and structure for doing so.

Hereinafter, with reference to FIG. 8 , when the player tracking apparatus 100 according to the embodiments of the present specification is worn, it will be described in detail that the reception sensitivity for the position signal can be improved.

8 is a schematic diagram illustrating a relationship between a radiation pattern formed from a GPS antenna module and a direction in which a position signal is transmitted when the player tracking device 100 according to embodiments of the present specification is worn.

Specifically, FIG. 8 shows the reception direction of the position signal and the maximum direction of the radiation pattern of the athlete tracking device 100 when the sports player 1 is upright. In addition, the receiving direction of the position signal in which the sports player 1 performs the sprint motion and the maximum direction of the radiation pattern of the athlete tracking device are shown.

The athlete tracking device 100 worn by the sports player 1 may include a GPS antenna module 140 and a reflector 160 . In this case, the radiation pattern emitted by the GPS antenna module 140 is a portion of the electromagnetic wave emitted by the GPS antenna module 140 as described with reference to FIGS. ), the central direction (RP10) of the radiation pattern is formed in the direction in which the central direction (RP1) of the radiation pattern generated from the conventional player tracking device 10 described in FIG. 3 is changed from the Y-axis to the Z-axis can be In other words, since the reflector 160 can move the radiation pattern of the receiving surface of the GPS antenna module 140 upward, the central direction RP10 of the radiation pattern transmits a position signal than the conventional player tracking device 10 . can be moved upwards.

Alternatively, by installing the GPS antenna module 140 in the housing to face one side 122 of the housing or to be inclined toward one side 122 of the housing, generated from the existing player tracking device 100 The central direction RP10 of the radiation pattern may be formed in a direction in which the central direction RP1 of the radiation pattern is changed from the Y-axis to the Z-axis. In other words, since the GPS antenna module can be mounted in the housing so that the receiving surface of the GPS antenna module 140 faces upward, the receiving surface is inclined at a predetermined angle with respect to the circuit board, the radiation pattern center direction (RP10) This conventional player tracking device 10 can be moved upwards where the position signal is transmitted.

The central direction (RP10) of the changed radiation pattern is directed toward the direction (Z') in which the position signal is transmitted or the direction (Z') in which the position signal is transmitted, than in the conventional case that does not include the reflector 160 can be tilted Accordingly, when the player 1 wears the player tracking device 100 disclosed in the present application and stands upright, the reception sensitivity of the position signal may be improved.

In addition, since the sports player 1 wears the athlete tracking device 100 on a part of the body, for example, the back, as the center of gravity of the sports athlete 1 changes, the The radiation pattern of electromagnetic waves radiated from the GPS antenna module 140 is also changed.

In particular, when the sports player 1 performs an operation such as a sprint, the radiation pattern of the GPS antenna module 140 is also affected by the movement of the sports player 1, so that the reception sensitivity to the GPS signal is not constant or decreased. There may be a possibility that Therefore, when performing an operation such as a sprint, it may be relatively more required to increase the reception sensitivity for the GPS signal than when the sports player stands upright or moves little.

At this time, in consideration of the change in the center of gravity of the sports player 1, the installation position or installation size of the reflector 160 so that the radiation pattern of the electromagnetic wave radiated from the GPS antenna module 140 is optimal for receiving the position signal. , a separation distance from the GPS antenna module, etc. may be considered.

Referring back to FIG. 8 , the radiation pattern emitted by the GPS antenna module 140 is a part of the electromagnetic wave emitted by the GPS antenna module 140 as described with reference to FIGS. 4 to 7 . The central direction (RP2) of the radiation pattern generated from the conventional athlete tracking device 10 described in FIG. ) may be configured such that the central direction (RP20) of the radiation pattern is formed in a direction changed from the Y-axis to the Z-axis.

Alternatively, the GPS antenna module 140 is installed in the housing to face one side 122 of the housing or to be inclined toward one side 122 of the housing, and the change of the center of gravity for the movement of the sports player 1 By additional consideration, the central direction (RP2) of the radiation pattern generated from the existing player tracking device 10 is changed from the Y-axis to the Z-axis can be configured so that the central direction (RP20) of the radiation pattern is formed.

Specifically, when the sports player 1 performs the sprint motion, in a state in which the housing 120 is inserted into the pocket formed on the clothing worn by the athlete, the ventral side of the housing faces upward or tilts upward. can get At this time, the receiving surface of the GPS antenna module 140 mounted in the housing and also the rear surface of the housing 120 face upward, so that the position signal may be transmitted upward or may be inclined upward. Therefore, When performing the sprint operation, the radiation pattern of the GPS antenna module 140 may be moved from the Y-axis to the Z-axis direction.

The center direction (RP20) of the changed radiation pattern is directed toward the direction (Z') in which the position signal is transmitted or the direction (Z') in which the position signal is transmitted, than in the conventional case that does not include the reflector 160 can be tilted Accordingly, when the sports player 1 wears the athlete tracking device 100 disclosed in the present application and performs a sprint operation, the reception sensitivity of the position signal may be significantly improved.
