The device detects 201 real-time acceleration at two or more points of the instrument. The acceleration detecting means is installed at one or more points of the glove worn on the batter's hand, and the swing trajectory can be detected more accurately by interlocking with the acceleration detecting means installed in the ball striking mechanism.

The real-time velocity is calculated by integrating at least two points of the ball hitting mechanism detected in the moving state, and the position is calculated by integrating the real-time velocity of two or more points again.

The slope of the ball striking device is set by comparing the position detected and calculated at two or more points, and the real-time speed or the real-time position or the real-time slope is calculated by comparing the ball striking device with the slope detected in the stationary state. (202).

In operation 211, the ball is simulated to fly.

3 is a flowchart of a swing simulation system operation.

A swing simulation system, a method thereof, and a program thereof for implementing the present invention will be described in detail with reference to FIG. 1A and FIG.

The swing simulation system operation flowchart is for explaining a system, a method and a program for detecting a swing of a batter hitting a ball by applying acceleration detection means.

In the following description of golf as an example, the mechanism for hitting the ball is called a club.

In a state where power is supplied to the RFID reader 121 of the main devices 120A and 120B installed on the glove worn on the batter's hand, the batter of the club having the antenna 114 of the RFID tag installed to hit the ball. When the grip is held by a hand wearing a glove in which the antenna 114 of the RFID reader is installed, the antenna 114 of the RFID reader and the antenna 114 of the RFID tag are in a proximity 311 state and the antenna of the RFID reader. The energy emitted from the 114 is induced to the antenna 114 of the RFID tag so that power is supplied to the RFID tag 112 so that the detection device 110 operates. At this time, the RFID reader 121 is in a state capable of exchanging information through communication by automatically detecting the RFID tag 112 (Auto-ID system) 341, and the microcomputer of the detection device 110 RFID tag 112 113 is controlled by the microcomputer 113 of the RFID reader 121 of the main apparatus 120A, 120B to operate 321 the acceleration detecting means 111, and detect the swing of the batter in real time.

When the club is at rest, the acceleration detecting means 111 of the detecting device 110 is in a static acceleration state, and the slope is measured. When the club starts swinging, the acceleration detecting means 111 of the detecting device 110 is dynamic. It is in an acceleration state and the acceleration is measured.

At the moment when the batter takes the ready posture (address) to hit the ball, the acceleration detecting means 111 measures the tilt of the club 322 and swing detection program 131 of the microcomputer 113 of the main device 120A, 120B. As a result, it is checked whether the batter is inclined to prepare to hit the ball, and the reference coordinate on the swing trajectory, which is the starting point (0) of the club head swing, is set (342).

In the state in which the reference coordinate is set 342 on the swing trajectory, which is the starting point of the club head swing, the batter starts swinging and the club moves so that the acceleration detecting means 111 is activated 323. Real-time acceleration of the 324 is measured, the acceleration is measured at two points in the longitudinal direction of the club.

The acceleration measured at two points of the detection device 110 installed in the club is integrated according to the swing detection program 131 to calculate the real-time speed of the two points, and the speed is integrated again to calculate the real-time position of the two points. In addition, the real-time position coordinates of both ends of the backswing club are set (343).

The slope of the club is set 344 by comparing the position coordinates of the two points set at both ends of the club.

The first real-time positional coordinate of the backswing set as described above is calibrated to the more accurate swing start point (0) by comparing with the reference coordinate on the swing trajectory which is the swing start point (0). The same applies to the starting point.

The positional coordinates and the slopes of both ends of the club become basic information for simulating the mechanism of hitting the ball in the three-dimensional virtual space of the X, Y, and Z axes of the computer.

When the club starts from the starting point (0) of the backswing and backswing, the acceleration detecting means 111 detects the acceleration, and the real-time position coordinates 343 and the real-time slope 344 on the backswing trajectory are continuously set and stored on the backswing trajectory. do.

When the acceleration detecting means 111 is operated 323 and the real-time acceleration measurement 324 of the backswing track is completed, the club reaches the position of the tower which is the peak of the backswing, and the acceleration detecting means 111 is in the instantaneous stop state 325 ), The acceleration detecting means 111 measures the inclination of the top position (326).

The final backswing real-time position coordinate set as described above is calibrated to a more accurate top position compared to the reference coordinate set to the top position slope, and the calibration method is also applied to the finish which is the vertex of the follow-through.

In the microcomputer 113 of the main device (120A, 120B), the top position reference coordinate is set by comparing the slope 326 of the top position measured by the acceleration detecting means 111 with the final slope 344 of the backswing trajectory (345). The top position reference coordinate is compared with the standard swing data of the batter previously stored in the swing detection program 131 to check the measurement state of the swing in real time.

After the inclination 326 of the top position and the top position reference coordinate are set 345, the acceleration detection unit 111 is operated 327 to measure 328 the real-time acceleration of the downswing trajectory. Integrate the acceleration in time to calculate the speed in real time, and integrate again in time to calculate the location of the real time to set the real time coordinates of the downswing (346), downswing by comparing the set real time coordinates (346) The real time slope of the step is set 347.

The microcomputer 113 includes a real time coordinate 346 and a real time tilt 347 set in the downswing trajectory using the slope 326 of the top position and the reference coordinate 345 of the top position as starting points of the downswing. Successively stored in the memory 122.

When the real time coordinates 346 and the real time tilt 347 of the downswing trajectory are compared with the standard swing trajectory data stored in the swing detection program 131 of the microcomputer 113, it is determined that the moment 348 immediately before the impact. The speed of the instant 348 immediately before the impact is extracted and stored 122.

Immediately after passing the moment 348 immediately before the impact, the club head is in an impact state colliding with the ball, and the acceleration detected by the operation 329 of the acceleration detection means 111 is rapidly reduced rapidly after the club head is impacted with the ball. do.

As a method for detecting the speed just before the impact and the speed immediately after the impact, the ball is stored as information for calculating the distance and the emergency trajectory, and the acceleration detection means operation 329 immediately after the acceleration is reduced by the impact is performed in the follow-through step. Acceleration is measured 330, the microcomputer 113 integrates the acceleration in time to calculate the real-time speed, and again in time to calculate the real-time position to set the real-time coordinates of the follow-through (350), The real-time slope of the follow-through orbit is set by comparing the set real-time coordinates 350 of the follow-through.

When the acceleration detecting means 111 operates 329 and the real-time acceleration measurement 330 of the follow-through track is completed, the club reaches the finish position which is the peak of the follow-through so that the acceleration detecting means 111 is in the instantaneous stop state ( 331, the acceleration detecting means 111 measures the inclination of the finish position (332).

The microcomputer 113 sets the finish position reference coordinate by comparing the inclination 332 of the finish completion position measured by the acceleration detecting means 111 with the final inclination 351 of the follow-through trajectory, and sets the reference coordinate of the position. Is compared with the data of the swing detection program to check the detection state of the swing in real time and store it in the memory 122 (352).

The information 352 stored in the memory 122 of the main device 120A or 120B is executed by the swing simulation program 132 in a computer or a mobile phone connected to the Internet or wired communication, so that the ball and the motion of the batter swing. It is information to simulate motion.

The detection device 110 installed in the club stores information about the club in advance, such as the length of the club, the angle of the club head, and the degree of bending of the shaft.

A graphic or video is produced in which the batter hits the ball according to the type of club.The axis of rotation formed by the club and the body is programmed with the batter's standard swing trajectory so that the real time coordinate and real time tilt swinging on the swing trajectory are matched.

4B is an explanatory diagram of a swing trajectory, and FIG. 5 is an explanatory diagram of a rotation shaft and a swing detection method.

A swing simulation system, a method thereof, and a program thereof for implementing the present invention will be described in detail with reference to FIGS. 1A and 1B and FIGS. 4B and 5 that illustrate golf.

In order to set the position where the club moves in the 3D virtual space of the computer, one or more clubs must be measured at the position and inclination, and the real-time tilt or real-time position coordinate at which the club moves on the swing track is installed at two club points. It is set as a means for detecting the acceleration.

In the detecting device 110 provided on the club rotating shaft 401 of the rotating shaft engaging portion 405, the three-axis acceleration detecting means 111 is provided at two or more points in the longitudinal direction of the club, and the batter hits the ball. In the address state, the club rotating shaft 401 and the body rotating shaft 402 are stopped, and the acceleration detecting means 111 is stopped, and the inclination is measured by the acceleration detecting means 111 provided at the two or more points and the club ( The slopes of the X, Y, and Z axes of 501 are calculated in three dimensions.

When the batter starts swinging, the starting point of the clubhead swing, which is the end of the club, is compared with the first two point positions set by the acceleration measurement, the slope calculated from the two point positions, and the slope of the address state. (0) and the starting point of the grip part swing (0 ") are set, and it becomes a reference point for setting the real-time position coordinates moving on the swing trajectory.

By comparing the inclination measured in the stationary state with the inclination and the inclination of the first or last two points calculated with the acceleration measured in the moving state in the above manner, the address position SW-1 or the top position SW -3) Or three-dimensional position coordinates of the X-axis and Y-axis and Z-axis of both ends of the club of the finish position (SW-6) is set, the position coordinates are compared with the information input to the swing detection program to determine a more accurate swing Is programmed to detect.

The slope of the address state measured by the acceleration detecting means 111 in the detecting device 110 is calculated by three-dimensional coordinates of the X axis, the Y axis, and the Z axis in the main device 120A, 120B, and the swing detection program of the program 130. 131 and the swing simulation program 132 is a starting point (0) of a swing simulating a swing in a virtual space, such as a computer or a portable terminal, and becomes a reference coordinate on a swing trajectory.

When the batter takes the address SW-1 to strike the ball 403, the acceleration detecting means 111 of the detecting device 110 measures the inclination of the club 501 and transmits it to the main devices 120A and 120B. The measured slope of the club 501 is set to the length of the pre-stored club, and sets the coordinates of the club head 404 and the rotating shaft coupling part 405 which are both ends of the club, and the club head 404. The backswing trajectory 406a and the backswing trajectory 406b of the rotary shaft coupling portion 405 are respectively set as starting points of the backswings 406a and 406b, respectively, and are represented by three-dimensional position coordinates of the X, Y, and Z axes, respectively.

As described above, the club head 404 position coordinates (0) of the club rotating shaft 401 and the rotating shaft (Z ') of the virtual body to which the body rotating shaft 402 is connected via the rotating shaft coupling portion 405 as described above. In the state where the center point (0 ') of the swing is set to virtual, when the back swings 406a and 406b are started, the acceleration sensor 111 operates to measure the acceleration in real time, and integrate the measured acceleration in real time to realize the speed in real time. The position coordinate is calculated by integrating the velocity in real time and calculating the position in real time.

The real-time position coordinate is connected to the club head 404 of the club rotation shaft 401 through the body rotation axis 402 at the center point (0 ') of the swing, the back swing track 406a at the starting point (0) of the club head 404 , Position coordinates are sequentially set according to step 406b).

When the body rotation shaft 402 and the club rotation shaft 401 start the back swings 406a and 406b clockwise at the starting point (SW-1) (0) of the swing, the acceleration detecting means 111 measures the acceleration at the inclination measurement. While switching to, the top position SW-3, which is the vertex of the backswings 406a and 406b, is reached while setting the real-time position coordinates, and the downswing 407a and 407b counterclockwise from the top position SW-3. And impacts the collision with the ball 403 through the impact direct current point SW-1 (0) through the downswing 407a and 407b orbit.

When the club head 404 passes through the impact point colliding with the ball 403, the axis of rotation will swing the follow through (408a, 408b), and the swing ends at the finish (SW-6) of the follow-through. The real-time position coordinates and the real-time inclination from the starting point SW-1 (0) of the swing to the finish SW-6 are sequentially set on the swing trajectory.

As described above, the body rotation shaft 402 and the club rotation shaft 401 reaching the top position SW-3 are in a pause state, and the acceleration detecting means 111 is switched to the tilt measurement, and the measured slope is measured in the back swing. Compared with the last position coordinates or the slope of the comparison, the determined position coordinates and the slope is compared to the slope and position coordinates of the standard swing trajectory previously input to the swing detection program 131.

The inclination and position coordinates compared to the standard swing trajectory, the club rotation axis 401, the body rotation axis 402 and the club head 404 can simulate a swing motion in which the batter hits the ball in a three-dimensional virtual space It is stored as information.

As described above, when the club head 404 reaches the position immediately before the impact while starting the downswings 407a and 407b at the top position SW-3 and setting the real-time speed and position coordinates on the downswing trajectory. The speed immediately before the impact is detected, and the position immediately before the impact (0) is a standard swing trajectory previously inputted to the swing detection program 131, the inclination of the club rotation shaft 401 and the body rotation shaft 402, and the club. It is programmed to determine the position immediately before the impact (0) by comparing the real-time position coordinates of the head 404, the speed immediately before the impact to calculate the swing trajectory and distance that the ball is flying, to simulate the motion of the ball 403 flying Stored.

 Acceleration measured by the acceleration detecting means 111 at the moment of impact of the club head 404 collides with the ball 403 is rapidly reduced, the ball 403 is calculated by calculating the difference between the acceleration immediately before the impact and the acceleration immediately after the impact. It can be used to calculate the flying swing trajectory and distance.

After the impact that the club head 404 collides with the ball 403, the club rotation shaft 401 and the body rotation shaft 402 swings the follow-through (SW-5), and follows the follow-through tracks 408a and 408b. Accordingly, the real-time position coordinates and the real-time inclination which are set continuously reach the finish position SW-6 which is a vertex.

As described above, the club rotation shaft 401 and the body rotation shaft 402 reaching the finish position SW-6 are in a pause state, and the acceleration measurement of the acceleration detection means 111 is switched to the tilt measurement, and the swing detection program The standard follow-through tracks 408a and 408b of the batter hitting the ball 403 previously inputted to 131 are stored by comparing the measured club inclination with the club head 404 in real time.

The X, Y, and Z axis three-dimensional accelerations of the backswing 406b, the downswing 408b, and the follow-through 408b detected by the acceleration detecting means 111 provided on the rotating shaft coupling part 405 are the detection apparatus 110. Is transmitted to the main device (120A, 120B), calculates the coordinates on the swing trajectory according to the real-time position and real-time slope, and converts the real-time coordinates of the club end point by substituting the length of the club previously stored in the detection device 110 Thus, swing trajectories 406a, 406b, 407a, 407b, 408a, and 408b of both ends of the club rotation shaft 401 at the time of the backswing 406a, the downswing 407a, and the follow-through 408a are set.

At the starting point (SW-1) (0) of the swing and the top position (SW-3) and the finish (SW-6) position, the club rotation shaft 401 and the body rotation shaft 402 are momentarily stopped, and thus acceleration detection means ( The slope is measured at 111, and the acceleration is measured by the acceleration detecting means 111 provided at two points in the longitudinal direction of the club during the backswings 406a and 406b, the downswings 407a and 407b, and the follow-throughs 408a and 408b. The inclination of the club rotation shaft is set by measuring and calculating the velocity and position, and comparing the coordinates of two points of the club rotation shaft 401. The slope and the position coordinate are set in three dimensions of X, Y, and Z.

The inclination of the body rotation shaft 402 and the real-time position coordinates and the center point of the body rotation (0 'point) position coordinates cannot be detected by the acceleration detecting means 111 provided in the detection device, but the acceleration detecting means 111 above. The position and inclination of the club shaft 401 measured by the reference are substituted into the standard swing trajectory previously inputted to the swing detection program 131, so that the X, Y, Z of the club head 404 and the shaft coupling portion 405 are By comparing and determining the three-dimensional position coordinates, the inclination of the body rotation axis 402 and the real-time position coordinates and the center point (0 'point) position coordinates of the body rotation is virtually set.

When the acceleration detecting means 111 is installed in the detection device 110 and the main device 120, the real time position and inclination of the club rotation shaft 401 and the real time position and inclination of the body rotation shaft 402 are detected, so that the swing trajectory is more accurate. It is possible to set the position coordinates of the phase, and the position coordinates of the center point (0 'point) of the body rotation is virtually set by comparing with the standard swing trajectory previously input to the swing detection program 131.

As described above, when the acceleration detecting means 111 are respectively installed in the detection device 110 and the main device 120B installed in the body rotation shaft 402, the positions of both ends of the body rotation shaft 402 are installed. Coordinates and tilts and the position coordinates of the center point of the swing (0 ') are more precisely set, and the real time bending or loosening angles of the club rotating shaft 401 and the rotating shaft engaging portion 405 of the club rotating shaft 401 and the body rotating shaft 402 are moved more accurately. You can measure accurately.

Since the length of the body rotating shaft 402 and the coordinates of the center point of the swing (0 ') may vary little by little depending on the condition, the acceleration detecting means 111 installed in the detecting device 110 and the main device 120B. The position of the real time and the slope of the real time, which are measured by, may be set more accurately than the standard swing trajectory of the swing detection program 131.

The information measured as described above and stored in the main apparatuses 120A and 120B becomes information that can be simulated by being transmitted to a computer or a portable terminal on which the swing detection program 131 or the swing simulation system 132 is executed.

5 is an explanatory diagram of a rotation axis and a coordinate setting method.

A swing simulation system, a method and a program thereof for implementing the present invention will be described in detail with reference to FIGS. 1A and 1B and FIG.

Two rotary shafts, which are connected to the body rotary shaft 402 and the club rotary shaft 401 at the center point of the swing (0 ') on the swing track having the rotary shaft Z' of the body as the center of rotation, are coupled to the rotary shaft coupling portion 405. .

The club rotating shaft 401 is a club 501 composed of a club head 404, a shaft and a grip 503, the detection device 110 is installed in the grip portion of the club rotating shaft 401 of the club 501 The data of the club 501 necessary for swing detection, such as the length and the loft angle of the club head 404, is stored.

Body rotation shaft 402 is a living body consisting of the arm and the body coupled to the club rotation shaft 401 with a hand wearing gloves, the rotation axis to move the swing trajectory, such as the length and position of the rotation axis in accordance with the condition of the batter will change little by little The measurement error, such as the length of the body rotating shaft 402 and the position virtually set on the swing trajectory, may be corrected by repetitive comparative determination and learning of the computer program 130.

The club rotating shaft 401 and the body rotating shaft 402 are connected to the grip 503 of the club 501 and the golf gloves worn on the hand, the detection device 110 on the grip 503 of the club rotating shaft 401. The RFID tag 112 is installed, the RFID reader 121 of the main device 120 is installed on the glove of the body rotating shaft 402, the RFID reader antenna 114 and the RFID tag antenna 114 is in close proximity Electronically coupled, the energy emitted from the RFID reader antenna 114 is induced in the RFID tag antenna 114 to supply power to the detection device 110, the RFID reader 121 automatically IDs the RFID tag 112 ID. You are logged in, and mutual information is exchanged.

Since golf is typically a game using about 15 clubs 501, a suitable club is selected according to the situation and swings to hit a ball and blows it to a desired position. Since it should be installed at 501, it should be possible to make it inexpensively, and the detection device 110 installed in the plurality of clubs 501 should be configured to minimize the weight and volume to minimize the influence on the structure and performance of the club. do.

The antenna 114 of the RFID tag is preferably manufactured in the same manner as the grip 503. The semiconductor device of the detection apparatus 110 is configured to be connected by a connector or a plug so as to be separated from the grip 503, and the club 501 Gloves worn on hands holding) are consumables that are frequently exchanged because they are dirty and dropped, so the RFID reader antenna 121 is made of the same body as the gloves, and the semiconductor elements of the main device 120 are connected by connectors or plugs so that they can be separated from the gloves. do.

In the sensing point 505 in which the portion of the sensing area 504 that is the combined portion of the club rotating shaft 401 and the body rotating shaft 402 is enlarged, the total length of the club rotating shaft 401 is a straight line AB, and the point D is a line segment AB. It is on a straight line which is internally divided, and the length of the straight line AB and the length of the straight line AD are determined and stored in the detecting device or the main device, and the point A and the point D on the club rotating shaft 401 and the point G of the body rotating shaft 402. And point H indicate the position of the acceleration detecting means 111.

In the state where the club shaft 401 is stopped, the acceleration detecting means 111 provided at points A and D is in a static acceleration state in which the acceleration of gravity acts, and the inclination is measured.

The slope measured at the point A and the point D is the same as the slope of the line AB of the club rotation axis 401, and the slope of the line AB is a horizontal axis or a vertical axis passing through the point A or the point B on the line AB. (Vertical axis) is set.

On the three-dimensional X, Y, and Z axes, the position of point A, point B, or point D in the right triangle ABC or right triangle DBE is a reference point (zero point) on a horizontal axis or a vertical axis. The position coordinate of point A or the position coordinate of point B or the position coordinate of point D is set.

As described above, when the club rotation axis 401 moves in a state where the position A or point B or point D is set on the three-dimensional X, Y, and Z axes in the stationary state, the acceleration provided at the points A and D The detection means 111 is in a dynamic acceleration state to measure the acceleration, and integrates the acceleration measured while the point A or the point D moves to calculate the speed at which the point A or the point D moves, and integrates the speed again. It calculates the real-time position where point A or point D moves.

When the position coordinates of the point A and the point D which are moved in real time are compared on three dimensions of the X, Y, and Z axes with the horizontal axis or the vertical axis as the reference point (zero point), the slope of the straight line AD can be calculated. The slope of the straight line AD is the same as the slope of the straight line AB of the club axis 401 on the same straight line. Therefore, it is possible to detect the tilt moving in real time using the two acceleration detection means 111 without using a gyro sensor.

Is set to the three-dimensional coordinates of the X, Y, and Z axes.

The position coordinates of the point A and the point B at which the club rotation axis 401 is moved in real time, and the slope information of the line AB changing in real time are substituted with information previously inputted into the standard swing trajectory of the swing detection program 131. It is possible to virtually set the position coordinates and inclination of the point A and the point F in which the body rotation shaft 402 is moved in real time.

In the address step for hitting the ball, the position coordinate of the point B which is the end of the club head 404 of the club rotation axis 401 is set to 0 point which is the starting point of the swing, and the position coordinate of the point A which is the grip part 503 Is set to 0 "point which is the starting point of the swing in the rotating shaft coupling portion 405, and the point F is set to the virtual 0 'point on the body rotating shaft 402 to the center point of the swing on the rotating shaft Z' of the body.

On the swing trajectory, the swing is centered around the center point (0 ') of the swing.

In the sensing point 505 in which the sensing area 504 is enlarged, a swing detection method of the body rotation shaft 402 that virtually sets the position coordinates of the points A and F and the slope information of the line AF is performed in the swing simulation process. There is a possibility that an error may occur, and in the main device 120 installed on the glove of the body rotating shaft 402, the acceleration detecting means 111 is formed at one or two points, and in conjunction with the acceleration detecting means 111 of the detecting device. The detection error of the body rotating shaft 402 can be reduced.

 The acceleration detecting means 111 installed in the main device 120 is installed at one or two locations at the point G or the point H on the line AF line of the body rotation shaft 402, and the points G and the point H inject the line AF. On the straight line, the length of the line AF and the distance between point A and point G and the distance between point F and point H are virtually set compared to the standard swing trajectory of the swing detection program 131, and two acceleration detections are performed. When the means 111 are configured, the distance between the point G and the point H is programmed to be calculated by the swing detection program 131.

When the acceleration detecting means 111 is provided at one of the points G or H on the line AF line of the body rotating shaft 402, in conjunction with the point A which is the acceleration detecting means 111 of the club rotating shaft 401, 2 The acceleration detection means 111 generates a right triangle AFI, a right triangle GFJ or a right triangle HFK to calculate a position or slope.

In the state where the body rotating shaft 402 is stopped, the acceleration detecting means 111 provided at the point A and the point G or the point H becomes a static acceleration state in which the acceleration of gravity acts and the inclination is measured.

The slope measured at point A and point G or point H is equal to the slope of the line AF of the body axis of rotation 402, and the slope of the line AF is a horizontal axis passing through the point A or point F on the line AF line. Or a vertical axis, and has a length of the line AF and a slope of the line AF, and a right triangle with respect to a horizontal axis or a vertical axis passing through a point A or a point F. AFI is formed, the horizontal axis having a length of the line AG or line GH or line HF and the slope of the line AG or line GH or line HF and passes through point A or point G or point H or point F or A right triangle AFI based on the vertical axis, a right triangle GFJ or a right triangle HFK is generated to calculate a position or slope. In the right triangle AFI or right triangle GFJ or right triangle HFK, the position of the point A or the point G or the point H or the point F is the horizontal axis (Horizontal axis) or the vertical axis (Vertical axis) as the reference point (0 point), X, Y , The position coordinate of the point A or the position coordinate of the point G or the position coordinate of the point H or the position coordinate of the point F on the three-dimensional plane of the Z axis.

The velocity at which point A or point G or point H moves is calculated by integrating the acceleration measured while the point A or point G or point H is moved, and the point A or point G or point H is integrated by integrating the velocity again. It will calculate the real time position being moved.

When the position coordinates of the point A and the point G or the point H, which are moved in real time, are compared on the three-dimensional X, Y, and Z axes of which the reference point (zero point) is the horizontal axis or the vertical axis, The slope of AG or straight line AH or straight line GH is calculated, and the slope of straight line AG or straight line AH or straight line GH can be confirmed to be the same as the slope of body axis AF 402 of straight line AF that is on the same straight line. Two acceleration detection means 111 can be used to detect a tilt moving in real time without using.

The position coordinates of point A and point F, which are the coordinates of both end points of the line AF, which are the body axis of rotation 402 that is moved in real time, and the slope of the line AF that changes in real time, and the position coordinates that are moved in real time are X and Y. In this case, three-dimensional coordinates of the Z axis are set.

The real time coordinates of moving the line A B of the club rotation shaft 401 and the line A F of the body rotation shaft 402 set as described above are detected by the swing detection program 131 and simulated by the swing simulation program 132.

Although the acceleration detection means is installed in the head part, which is the part of the club that collides with the ball, is the most effective means of detecting the swing trajectory of the club movement, the club head is the most sensitive and shocking part, which may hinder the performance of the club. In many parts, in order to install the acceleration detecting means in the head of the club, there is a problem in that the structure of the club needs to be changed so that the club can be deformed or detached.

On the other side of the clubhead, the hand-held grip is the least moving part of the club, so it is the most unfavorable means of detecting acceleration, but the device can be installed without compromising the performance of the club. There is an advantage in close contact with the wearing gloves.

The present invention has the advantage of providing the tag of the detection device and the radio frequency identification system in the club by connecting the assertion of the detection device and the glove of the club with a radio frequency identification system (RFID).

The RFID tag of the RF system installed in the club is automatically logged in by receiving power from an RFID reader configured in the batter's gloves, and wirelessly receives information detected by the acceleration detecting means. Since it is calculated and compared to the RFID reader, the device installed in the club can be minimized, thereby reducing the volume and weight.

The tags of the acceleration detection means and the radio frequency identification system (RFID Tag) are produced as nanoelectromechanical systems (NEMS) due to the development of information communication (IT) and nano (NT) technologies. It can be applied to a small size high performance radio frequency identification system tag.

The antenna of the RFID tag configured on the grip of the club and the antenna of the RFID reader configured on the glove of the batter holding the grip are used for the batter to hit the ball. Since the structure is in close contact with each other from the moment the club is held, it is easy to transfer energy between the antenna of the RFID reader and the antenna of the RFID tag, and thus it is possible to operate with a small power supply.

As described above, the main device configured in the batter's glove is provided with a radio frequency identification system reader (RFID Reader), and the acceleration detection means configured in the club is connected to a tag of the radio frequency identification system. (RFID: Radio Frequency Identification), the RFID Tag is recognized by the RFID Reader and is supplied with power to operate the acceleration detection means and wirelessly detect the detected acceleration information. It is configured to transmit to a RFID reader, and two or more acceleration detection means are provided in the longitudinal direction of the club to detect two or more accelerations or inclinations.

6 is an explanatory diagram of tilt and position coordinates of a rotating shaft.

A swing simulation system, a method and a program thereof for implementing the present invention will be described in detail with reference to FIGS. 1A to 5 and FIG.

The batter's action is to move the ball from its current position to the desired location, taking into account the terrain and the wind, choosing a club with the right angle of the clubhead and the right length of the shaft, so that the club can produce the desired distance. It is a projectile movement that swings a ball and impacts it with a stationary ball and draws a parabola at a desired angle and blows it to a desired place. At this time, the flying distance that the ball is flying is determined at the speed at which the ball impacts the clubhead, and the backswing 406, the downswing 407, and the follow-through 408 impact the clubhead to the ball so that the ball can fly at the desired speed. Projecting operation.

The swing motion is that the body rotating shaft 402 connected to the center point (0 ') of the swing and the club head 404 which is the end of the club rotating shaft 401 to impact the ball 403, the golf ball hitting the club Swing is a ball impact (SW-1) through the backswing (406), top (SW-3) and downswing (407) process in the ready position (SW-1) and then the finish (SW) process through the finish (SW) -6) is reached and terminated.

The club rotating shaft 401 and the body rotating shaft 402 are connected from the starting point 0 of the swing of the club head 404 to the center point 0 'of the linear swing of the rotating shaft Z' of the body, and the two rotating shafts 401, 402 is connected to the rotating shaft coupling portion 405.

When the batter hits the ball and connects the body rotating shaft 402 and the club rotating shaft 401 to the rotating shaft coupling portion 405 to take an address, the club rotating shaft 401 is stopped at the position C1, and the body rotating shaft 402 ) Becomes a stationary state at the A1 position, and the acceleration detecting unit 111 calculates the inclination angle of the horizontal direction φ1 or the vertical direction φ2 by measuring the inclination of the club rotation shaft 401.

The position of the club head 404, which is the end of the lower end of the club rotating shaft 401, is determined as the starting point of the swing on the swing trajectory (0), and the three-dimensional coordinates of the X, Y, and Z axes passing through the starting point of the swing (0) are set to the club. Set as a reference point for the head movement calculation, the length of the club axis 401 and the loft angle of the club head 404, which are connected from the club head 404 via the shaft to the grip 503, are stored in the system.

The club head 404 makes a right triangle of a, b, c having the length of the club rotation axis 401 and the inclination angle in the horizontal direction (φ1) or vertical direction (φ2) at the starting position (0) of the swing, The position coordinate (0 ") of the grip 503, which is the rotation shaft coupling portion 405 of the club rotation shaft 401, is calculated by the trigonometric function, and the position coordinates of both ends of the club rotation shaft 401, which are the starting points of the swing, are set. Set to 0 point and 0 "point, the grip 503 part coordinate (0") is the coordinate (0 ") of the rotary shaft coupling portion 405 connecting the club rotation shaft 401 and the body rotation shaft 402, swing On the track, the rotational shaft coupling portion 405 is positioned on the coordinate passing through the starting point 0 "of the swing.

The body rotation shaft 402 at the address position A1 is connected to the rotation shaft coupling portion 405 at the center point 0 'of the swing, and passes through the center point 0' of the swing on the line Z 'of the body. , Y, Z axis 3D coordinates are set, the inclination and length of the body rotation axis 402 of the address position (A1) is substituted by the standard swing trajectory of the batter input to the swing detection program 131, club rotation axis A grip that is a rotating shaft engaging portion 405 at the position of the body rotating shaft 402 A1 inserted into the position coordinate (0 ") of the grip 503, which is the rotating shaft engaging portion 405 of the (401) in the swing detection program 131 ( Coordinates (0 ") of the hand holding 503 are set to overlap.

Make a right triangle of a, b, c with the length of the body rotation shaft 402 and the inclination angle in the horizontal direction (φ1) or the vertical direction (φ2) at the starting position (0 ") position coordinate of the swing of the rotating shaft coupling portion 405. The position coordinate is set at the center point (0 ') of the swing of the body rotation shaft 402 by calculating with a trigonometric function, and then the swing trajectory of the back swing 406 and the down swing 407 and the follow-through 408 is drawn. This is the center point of the swing (0 ').

Acceleration detection means 111 is installed in the main unit 120A of the glove worn on the hand of the body rotating shaft 402, and the inclination of the horizontal direction φ1 or the vertical direction φ2 of the body rotating shaft 402 is measured, and the rotating shaft By measuring the acceleration at which the starting point (0 ") of the engaging portion 405 swing moves, the position coordinates of the starting point (0") of the rotary shaft coupling part swing and the center point (0 ') of the swing can be more accurately calculated.

The two rotary shafts that extend from the starting point (0) of the club rotary shaft swing to the center point (0 ') of the body rotary shaft swing through the rotary shaft engaging portion (0 ") have the end of the club head (404) as the starting point (0) of the swing. It is set as three-dimensional coordinates of X, Y, and Z, and is set as three-dimensional coordinates of X ", Y", and Z ", with the end of the grip 503 as the starting point (0") of the swing, and the axis of rotation Z ') Set the three-dimensional coordinates of X', Y ', Z' as the center point of the swing on the line (0 ') to draw the swing trajectory, and the center point of the swing on the line of rotation (Z') of the body (0 '). ) Will swing on the central axis.

When the back swing 406 is started at the postures of the addresses A1 and C1, the body rotation shaft 402 and the club rotation shaft 401 connected to the central axis of the swing at the center point 0 'are positioned at positions A2 and C2 at positions A1 and C1. And in the process of the backswing 406 to move to the A3, C3 position, by rotating the rotation axis (Z ') of the body (409) clockwise to accumulate the rotational torque, the rotary shaft coupling connecting the two rotary shafts The action of bending the portion 405 will generate torque of the human segment using the lever principle, thus accumulating more energy.

The angle of the body rotation shaft 402 at the back swing 406 is sequentially moved from θ1 to θ2 and θ3 with respect to the central axis Z 'of the body, and at the back swing 406 the body rotation shaft 402 and the club. The bending angle of the wrist connecting the rotating shaft 401 is bent from β1 to β2 and β3 to reach the top position as torque energy is accumulated more and more.

When the back swing 407 is started at the top positions A3 and C3, the body rotation shaft 402 and the club rotation shaft 401 connected to the center axis of the swing (4 ') rotate clockwise (409) to the center of the body. Rotational kinetic energy in which the two rotating shafts 401 and 402 rotate 410 counterclockwise as the torque energy stored in the rotating shaft Z 'is released from θ3 to θ2 and θ1, and the two rotating shafts 401 and 402. The potential energy accumulated in the A3, C3 to A2, C2 and A1, C1 is released, and the torque energy accumulated in the human body segment in the rotating shaft coupling portion 405 is released from β3 to β2 and β1, the club head is Strong impact (A1 C1) to hit the ball 403 is made.

After the club has undergone the impact (A1 C1) process, the swinging motion of the follow-through 408 generates greater acceleration by continuously applying force to the ball after impact, and inertia of the body caused by the downswing 407. By attenuating, the golfer is naturally directed to the finish.

The body rotation shaft 402 is connected to the swing center point (0 ') on the swing trajectory which rotates about the rotation axis Z' of the body, and the back swing 406 sequentially from the A1 position of the address to the A3 position. Rotating while drawing the trajectory, downswing (407) from the A3 position to the A1 position through the A2 position to rotate the drawing, and rotates while drawing the follow-through 408 from the A1 position to the A4 position to impact the ball. .

 Club rotation shaft 401 is coupled to the rotary shaft coupling portion 405 to the body rotation shaft 402 connected to the center point (0 ') of the swing, the backswing 406 orbit sequentially from the C1 position of the address to the C3 position Rotate while drawing, and rotates while drawing the downswing 407 orbit from the C3 position to the C1 position through the C2 position, and rotates while drawing a follow-through 408 trajectory from the C1 position to the ball C4 position.

At the top position of the backswing A3 and C3 and the finish position of the follow-through A4 and C4, the two rotation axes 401 and 402 stop momentarily, so that the acceleration detection means 111 measures the slope of the stationary state. The position coordinates just before stopping at the towers of positions A3 and C3 and the position coordinates just before stopping at the finishes of positions A4 and C4 are compared to measure more accurate position coordinates.

The slope and acceleration measured in the above manner are calculated by the swing detection program 131 and stored as information for simulating the motion of the batter hitting the ball later in the swing simulation program 132, and the club head 404. The speed just before impact colliding with the ball is calculated by the swing detection program 131 to calculate the distance the ball is flying.

The speed immediately after the impact of the clubhead 404 colliding with the ball is reduced than the speed just before the impact colliding with the ball, and the swing detection program 131 speeds up the speed difference immediately after the impact at the speed just before the impact of the clubhead 404. By calculating, the swing simulation program 132 can calculate the distance the ball flies in the future.

The velocity vector through which the clubhead passes through the impact zone (

Figure 112008057569273-PAT00012
At just before impact (
Figure 112008057569273-PAT00013
) Decreases significantly after colliding with the ball, resulting in the speed right after impact (
Figure 112008057569273-PAT00014
), And the speed before impact
Figure 112008057569273-PAT00015
) And speed right after impact (
Figure 112008057569273-PAT00016

Figure 112008057569273-PAT00017
, You can calculate the speed just before impact
Figure 112008057569273-PAT00018
) And speed right after impact (
Figure 112008057569273-PAT00019
Is calculated by integrating the acceleration detected by the acceleration detecting means.

Using the same principle as above, the vertical distance at which the ball flies away from the club head 1001 (

Figure 112008057569273-PAT00020
) And horizontal distance (
Figure 112008057569273-PAT00021
) And the time the ball flies (
Figure 112008057569273-PAT00022
) By synthesizing the background or flying ball 1002 programmed in the swing simulation program 132 to a graphic or an image to simulate the motion of the ball flying.

According to the law of conservation of momentum, the speed at which the ball leaves the clubhead (

Figure 112008057569273-PAT00023
) Is the speed of the clubhead at impact
Figure 112008057569273-PAT00024
), So the flying distance of the ball (
Figure 112008057569273-PAT00025
