Particularly, the main body 100 senses and analyzes such analysis without any switch operation, and provides analysis results. More specifically, the main body 100 senses whether or not the user has made an aiming (or aiming) action, and after recognizing the aiming direction, analyzes the swinging information after the aiming. If there is no ame, such as practice, or when the ame is intermittently performed, the exercise is recognized as a practice and the swing is repeatedly collected and analyzed. .

The processing unit 110 of the main body 10 collects the swing information generated during the swing by the sensor unit 120, analyzes the swing information, and provides analysis results. For this purpose, the processing unit 110 analyzes the state of the determination and the swing using the sensing value provided from the sensor unit 120. In particular, the processing unit 110 outputs the analysis information through the display unit 140 or transmits the analysis information to an external device such as the user terminal 200 through the communication unit 160. The swing analysis by the main body 10 and the processing unit 110 will be described in more detail below with reference to other drawings.

The sensor unit 120 measures various indexes generated during the swing and transmits the measured indexes to the processing unit 110. Particularly, the sensor unit 120 scans the sensor tag 101 when the main body 100 is attached to or detached from the golf club 10, collects information on the golf club 10 to which the main body 100 is detachably attached, And transmits it to the processing unit 110. The communication with the sensor tag 101 can be performed by detecting the attachment or detachment of the golf club 10 and the processing unit 110 analyzes the detection value of the vibration or displacement caused by the attachment or detachment of the golf club 10 to determine the detachment / And the processing unit 110 requests the sensor unit 120 to scan the sensor tag 101 accordingly. Or the sensor unit 120 may check the sensor tag 101 at a predetermined period of time, but the present invention is not limited by the presented aspects.

The sensor unit 120 includes a tag reader 121, a gyro sensor 122, and an impact sensor 123.

In addition to the gyro sensor 122 and the impact sensor 123, the present invention may include sensors for more accurate swing analysis. For example, the acceleration sensor 124, the compass sensor 125, (126).

The acceleration sensor 124 measures a change in the acceleration generated during the swing of the golf club 10 and transmits the measured acceleration value to the processing unit 110. The processing unit 110 determines the speed and direction of each section of the swing trajectory consisting of the aiming, the backswing, the impact, and the follow-up using the acceleration value, and performs the swing trajectory analysis together with the measured value of the gyro sensor 122 .

The compass sensor 125 measures the change of geomagnetism caused by the stop and movement of the golf club, and transmits the measured geomagnetism value to the processing unit 110. The processing unit 110 uses the geomagnetism value measured by the compass sensor 125 as data for determining whether a sweet spot is hit at impact or a change in a swing locus. Specifically, the processing unit 110 detects a change in the height, position, and direction of the golf club by comparing the geomagnetism value at the time of alignment with the geomagnetism value at the time of the swing and the impact and uses the value together with the value of the gyro sensor 122, .

The temperature sensor 126 measures the temperature around the golf club 10 and transmits it to the processing unit 110. The processing unit 110 calculates the air density, the change in elasticity of the golf ball and the ball using previously stored data and algorithms using the temperature information, and applies the swing analysis to the analysis. Through this, the processing unit 110 can more accurately calculate the actual values of balls of various balls such as a ball, a ball, a ball, a push, a draw, and a slice.

The power supply unit 130 supplies power for operation of the main body 100. The power supply unit 130 may be constructed using a rechargeable secondary battery or a replaceable battery, and any means may be used as long as it is a power supply capable of supplying light and stable power.

The display unit 140 outputs and provides data provided from the processing unit 110. To this end, the display unit 140 may include a device such as a small liquid crystal or OLED display screen, an LED capable of multicolor lighting, a speaker capable of outputting sound, and a vibration motor capable of outputting vibration. The display unit 140 may display the data output from the processing unit 110 in a simple image form on a display screen and provide the data in a simple image form or may display a multicolor LED such as green, So that the status of the main body 100 can be determined. In addition, when voice output is possible, it is possible to guide the user through voice, to adjust the intensity and length of vibration, or to transmit information such as the alignment status using a specific symbol (+, -, <,>, etc.) However, the present invention is not limited thereto.

The storage unit 150 stores various sensing values transmitted from the sensor unit 120, algorithms for swing analysis, and swing analysis results. The storage unit 150 may be a removable memory such as a micro SD card, but it is also possible to use a fixed memory.

The communication unit 160 forms a wired or wireless communication channel with an external device such as the user terminal 200 and transmits the swing analysis result transmitted from the processing unit 110 or the data used for the swing analysis. To this end, the communication unit 160 may include a USB port and a LAN (local area network) port in addition to a short-range wireless communication such as Wi-Fi and Bluetooth. Here, the user terminal 200 may be a device such as a user's smart phone or a computer in addition to a dedicated terminal for analyzing a swing and providing a result, but the present invention is not limited thereto.

FIGS. 3 to 5 are illustrations for explaining an example of use of the swing analysis according to the present invention. 3 is an illustration showing an example immediately after impact of a golf ball and a golf ball, and FIG. 4 is an illustration showing an example of analyzing a hit by a golf club at the time of impact.

3 to 5, the golf swing training assistance device according to the present invention automatically recognizes the aiming and analyzes the trajectory of the swing after the aiming, thereby performing trajectory analysis of the ball, ballistic analysis such as distance, And the swing trajectory and velocity of the swing, and provides various information necessary for the practice and practice of golf in practice and actual game.

3 and 4, the main body 100 of the golf swing practicing assistance device measures various indexes generated by the swing using the sensors provided therein, And the analysis value is calculated. 3 and 4, the main body 100 senses the traveling direction of the head 16 of the golf club 10 according to the swing and whether the head 16 is opened, closed, or blown in the forward direction Calculates the power at the time of swing and calculates information such as a distance, a direction and a head angle and provides the information to the user through the display unit 140 or the communication unit 160 or stores the information in the storage unit 150.

The start of this swing analysis can be done by Aiming. In the case of using the golf swing practice assisting device of the present invention, the aiming operation starts the analysis of the main body 100 and also serves to inform the target direction so that the main body 100 can analyze the swing and the trajectory do. That is, the user performs a predetermined series of operations, and when the main body 100 senses this, the main body 100 determines that the aiming has been performed, and recognizes the direction specified by the aiming as the target direction.

In addition, if the user performs an alignment for batting or a hit by an actual swing, the accuracy of ballistic trajectory, distance, and accuracy of alignment are analyzed based on the target direction.

Such an aiming operation can be performed at the same time in practice as in an actual game. However, in practice, once the target direction is determined by the aiming, the swing analysis is performed according to the initially set target direction when the repeated swing and hit are performed. The aiming operation may reflect the habit of the user or the general golfers, and may allow the main body 100 to recognize the specific arrangement of the golf clubs without any special operation. Specifically, the user may hold the golf club for a few seconds while lifting the golf club to a predetermined height, adjusting the golf club on the floor and lifting it again, or keeping the golf club horizontal for a predetermined time It is possible to judge that amming is performed. The recognition of the action of the aiming can be recognized by a sensor such as a gyro sensor or a compass sensor constituting the sensor unit 120. [

When the operation according to the aiming condition is performed, the main body 100 informs the user that the specific color of the external LED is turned on, or that the amming has been performed through the display screen, speaker, Notify. If it is judged that the user is re-amming or is not amming and recognized as amming in the similar operation, it is possible to carry out the re-arming operation again to carry out the re-arming and thereby perform the game or practice.

When the swinging and the hitting are performed as described above, the main body 100 senses various indices, and detects head speed, slices, hooks, pushes, pulls, Swing analysis such as the degree and direction of occurrence of the ball, the impact position, the degree of opening / closing of the ball, the ball trajectory, the distance of the ball, the rotational speed of the ball, the overall trajectory of the golf club, and the segment acceleration (backswing, impact, .

5 is an exemplary diagram showing an example of swing analysis.

The main body 100 recognizes an indicator in the state where the golf clubs are aligned for batting or swing since the aiming, for example, the height direction of the golf clubs is recognized by the gyro sensor 122 or the compass sensor 125 . When the swing is started, the gyro sensor and the compass sensor 125 as well as the acceleration sensor 124 measure the acceleration generated by the golf club. When the impact is detected, the impact sensor 123 senses the impact. The processing unit 110 receives the sensing data of the sensor unit 120 from the sensors and performs the swing analysis as described above. Particularly, in this process, the temperature value measured by the temperature sensor 126 included in the sensor unit 120 is applied to the swing analysis, and the changes such as the change of the elasticity of the golf club and the change of the distance by the air density are applied to the swing analysis To analyze important factors such as accurate distance, trajectory, power and torque.

Specifically, as shown in FIG. 5, the RB of the head may be calculated at the time of impact by using the sensing value of the sensor unit 120. FIG. 5 is an exemplary view for explaining that ball points such as top ball, sweet spot, and under ball can be detected to be formed at any point in the vertical direction with respect to the ground. In general, the golf ball will fly with optimal trajectory when the center or slightly lower portion of the ball is centered on the head 16. However, in order to hit such a sweet spot, the swing must be stable and the user must be aware of how his or her swing changes during alignment and during actual impact, so that it can be corrected.

In the present invention, the gyro sensor 122 of the main body 100, in particular, the compass sensor 125 constituting the compass sensor 125 measures the displacement value at the time of alignment and measures the displacement at the time of impact, . Also, at this time, it is possible to predict a floating ball, an appropriate ball, and a low balloon according to the RB points, and through this, the processing unit 110 can calculate the distance increase / decrease and perform distance analysis. In addition, when the measured values of the gyro sensor 122 and the impact sensor 123 are additionally used, it is possible to determine whether the head is hit or tilted in a state where the head is perpendicular to the ground.

Accordingly, the golf swing practice aids according to the present invention can be used for correcting the posture by confirming items such as the distance, pitch, spot, and trajectory of the ball, as in an actual game, even during practice, It is possible to check problems such as ballistics and apply them to a game.

In particular, since the auxiliary device of the present invention is not built in a golf club, it can be easily used even when the user changes the golf club.

FIGS. 6 to 9 illustrate a process of measuring various elements in an actual game using a golf club equipped with an auxiliary device. FIG. 6 illustrates an example of a method of measuring a distance from a current position to a target Fig. 8 is an exemplary view for explaining a method of measuring a right angle slope of a ball path, and Fig. 9 is a view for explaining a method of measuring a straight line inclination to a target in Figs. 6 to 8 FIG. 2 is a diagram illustrating an algorithm guide process performed according to a value calculated by FIG.

6 to 9, the practice assisting device of the present invention is detachably attached to a golf club as described above, and it is possible to calculate and analyze information related to golf swing by various sensors. In addition, the practice aiding device of the present invention can be used not only in indoor practice fields but also in various environments, particularly in actual games, and it is possible to provide more accurate and detailed information than the information provided to the golfer by the caddy. The provision of such information may be accomplished by data processing with various sensors configured in the body.

First, as shown in Fig. 6, it is possible to easily calculate the distance to the target and provide this distance information to the user. Specifically, as described above, the sensor units 120 of the main body 100 collect various data according to the movement of the golf club and transmit the collected data to the processing unit 110. Using the data, the processing unit 110 determines whether or not an aiming And performs processing such as swing analysis. The position of the hole 15 and the position of the target, for example, the hole H are recognized and the distance B between the hole H and the hole 15 is calculated as shown in this aging process, It is possible to provide the distance information to the user.

For example, in the storage unit 150 of the main body 100, a sensing value corresponding to a specific position (or posture) of the golf club may be recorded in advance and a classification information of an operation performed by the user at the corresponding position. That is, when the golf club 10 is held for a predetermined time or more in a state where the golf club 10 is horizontal to the ground, as in the case of the aiming, the sensing value sensing the position and posture of the golf club during alignment, The processing unit 110 can confirm the operation corresponding to the specific position of the golf club and can analyze the golf club. When it is recognized that the golf club position and attitude A during alignment and the attitude C indicating the target are repeatedly or continuously generated, it is possible to calculate the distance B between the alignment position and the target , And the calculated distance information may be outputted through the display unit 140 and provided to the user. That is, when the user places the golf club 10 on the field, the user recognizes the golf club 10 by the sensors of the sensor unit 120 and measures the inclination of the golf club in the direction parallel to the shaft, The slope of the straight line between the hole H and the hole 15 or the slope of the hole path can be measured. The inclination may be calculated by data transmitted from the sensors by the processing unit 110, output through the display unit 140, and provided to the user.

Also, as shown in FIG. 9, information for adjusting the alignment direction can be provided. Specifically, the processing unit 110 calculates the distance information, the linear gradient, or the left-right inclination to the target calculated through the above-described FIGS. 6 to 9, and stores the calculated information in the storage unit 150. The processing unit 110 may use this information to adjust the alignment direction or the aiming direction. That is, the processing unit 110 calculates the direction in which the actual hitting should be performed, the distance the ball 15 must travel by using the distance to the measured target and the inclination of the ground, and outputs the calculated distance through the display unit 140 . The guide of the output direction can be guided through a symbol easy to be recognized by the user such as +, -, >, < through the display unit 140, or can be guided using a combination of symbolic numbers and voice. More specifically, when the user performs an operation for aiming, tilting, or measuring a distance to perform a putting or a shot, the main body 100 recognizes this. After the analyzed information is checked and the user aligns the ball with the club, the main body 100 provides information such as the distance to the target and the inclination through the display unit 140, and provides information for adjusting the alignment direction .

 The processing unit 110 can control the virtual target point HT so that the user can send the ball to the path T1 in which the ball 15 can approach the actual target hole H as shown in Fig. And the route T2.

The user can use the information provided by the processing unit 110 to send the ball 15 to the actual target point H by striking the ball by realigning the virtual get point HT and the path T2.

It is also possible to measure the slope of the field as shown in FIGS. 7 and 8, and output the measured value through the display unit 140. FIG.
