In general, golf provides a hole cup at a certain distance and hits a golf ball with a golf club such as a driver to put a golf ball in the hole cup. Say.

There are various golf clubs that vary in material, length, shape of head, material of head, weight of head and loft of club head (vertical tilt of club head face). Choose the club that best suits your needs and play the hole cup on the tee ground.

Golf clubs consist of wood, irons, and putters, and woods and irons are numbered according to the length of each club and the vertical slope of the club face. Wood is numbered in the order of 1, 3, 4, 5, 7, and the smaller the number, the longer the shaft and the smaller the loft, the greater the distance. For irons, the shaft length is shorter and the slope of the face is shorter than the 9 irons, such as pitching wedges and sand wedges, which are used for irons and approaches up to 3, 4, 5, 6, 7, 8, and 9 on a full set basis. There is a large iron and each iron is different in the length and loft of the shaft will cause a difference in the trajectory of the golf ball.

These golf clubs differ in the distance of the golf ball and the spin of the golf ball after hitting according to the characteristics of each club, but in the conventional golf simulating device, the golf club uses the data and rules prepared in a batch to estimate what club the golfer currently uses. There was a problem that the accuracy and detail of the simulation was inferior because there was no sensing at all. That is, after measuring the trajectory of the golf ball, the golfer's angle is estimated by the angle of the golf ball, and the approximate backspin value when the golfer is hit is used to roughly simulate the trajectory of the actual golf ball. There was a problem that could not accurately reflect.

Hereinafter, a golf simulating device using a golf club identification device according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a golf simulating device using the golf club identification device of the present invention.

Golf simulating device using the golf club identification device of the present invention senses the club identification unit 100 and the track of the ball hit the golfer and the club used by the golfer to identify the club in use in the simulated golf course sensing The calculation unit 300 calculates the trajectory of the ball to be simulated on the golf course being simulated using the unit 200 and the identified club type, the spec data of the club, and the trajectory of the ball sensed by the sensing unit 200. It is made, including.

The club identification unit 100 identifies the type of club used by the golfer rounding on the simulated golf course, receives the spec data of the corresponding club, etc. and calculates the data to the calculation unit 300 for calculating the trajectory of the ball to be simulated. To pass.

As described above, there are various types of clubs, and each course has a variety of shapes and battlefields, so golfers select and use an appropriate club according to the situation. The golf club is divided into a shaft and a head and has a rubber grip at the end of the shaft.

4A, 4B, and 4C, as shown in FIG. 4A, the vertical tilt of the face surface of the head is called a loft, and the lower the number of woods or irons, the smaller the loft. This is related to the use of golf clubs. In the case of wood, the length of the club shaft is longer and the loft is smaller than the accuracy, while the length of the shaft is smaller and the loft is larger for the accuracy than the distance. In addition, the smaller the club number in the wood or iron, the smaller the loft and the longer the shaft.

Referring to FIGS. 4B and 4C, the trajectory of the ball according to the loft appears. When the ball is exactly centered on the club face, the smaller the loft, the lower the trajectory formed (the upper and lower trajectories of the ball) and the higher the trajectory. In addition, the loft also affects the spin formed on the ball when hitting. The larger the loft, the more the backspin takes and the smaller the rolling distance from the ground, while the smaller the loft, the less the backspin, the more rolling distance from the ground. . In addition, the smaller the loft, the more the ball and the club face meets almost vertically, so that the amount of spin formed left and right, while the larger the loft, the ball and club face are in contact with the lower end of the ball, the smaller the amount of spin formed left and right.

As described above, the ball trajectory and the type and size of spin formed on the ball vary depending on the type of club used by the golfer. Was estimated and used to calculate the trajectory of the ball to be simulated. Because of this, there is a problem that the trajectory of the simulated ball is inaccurate and the golfer feels a difference from the actual field.

Club identification unit 100 of the present invention is attached to the club, for example, the club data storage unit 110 and the club data storage unit 110, which contains the specification data for the club, etc. wirelessly connected to the data for the club It may be made of a receiver unit 120 for receiving the (first embodiment).

Club data storage unit 110 contains the type of the club and the specification data for the club. Of course, other information except specification data may also be included within the capacity allowed.

The receiver unit 120 receives data about the club stored in the club data storage unit through a wireless connection with the club data storage unit 110 and transmits the data to the calculation unit 300.

The club data storage unit 110 and the receiver unit 120 may be any device capable of transmitting and receiving data through a wireless connection. However, in consideration of economical efficiency, a wireless method in which the club data storage unit 110 and the receiver unit 120 is one-way is preferable rather than expensive two-way communication.

Of course, if you don't consider the cost, you can use a wireless method that allows two-way communication such as Bluetooth or Zigbee.

Club identification apparatus 100 in the first embodiment of the present invention comprises a club data storage unit 110 consisting of an RFID tag and an RFID reader 120 for receiving information stored in the RFID tag. RFID stands for Radio-frequency Identification and refers to a technology that recognizes remote information using radio waves. It is classified into active and passive types. Active means that the tag itself has a power source, which enables high-speed communication and has a large storage capacity, but is expensive. On the other hand, passive type does not have its own power and reads the information of the tag by the power of the reader. Instead, it communicates at low speed and does not have a large storage capacity.

In the present invention, since the amount of data stored in the club data storage unit 110 including the spec data of the club is not very large and there is not much need for high speed communication, it is preferable to adopt a passive RFID in terms of price. In addition, since the club data storage unit 110 is to be attached to each club, it is preferable that the manual type can be made compact.

Club identification device 100 made of a passive RFID method is advantageous as the distance between the club data storage unit 110 and the receiver unit 120 made of RFID tags is shorter as the recognition distance is less than 1.8 m. Attaching an RFID tag to the connection of the club head 20 and the shaft 10 can minimize the distance between the tag and the reader as shown in FIG. It also has the advantage of minimizing the interference on the swing.

In the present invention, in addition to the RFID tag and reader, a new short-range wireless communication standard Ruby (RuBee: IEEE 1902.1) can be used to identify the club. Consists of the club data storage unit 110 made of ruby tags and the receiver unit 120 made of ruby readers, the ruby method is capable of producing inexpensive communication without obscuring objects and producing a relatively long communication distance and low cost. There is this. Ruby, unlike RFID, uses a signal from a magnetic field, and even though it is covered in aluminum foil, it has the advantage of being able to communicate. However, the recognition speed of the information is only 10 times per second, which is significantly lower than 100 to 200 times per second of RFID.

In the second embodiment of the present invention, as shown in FIG. 3, the club identification unit 100 detects the cover unit 130 and the cover unit 130 attached to the club to detect the club unit 140. And a database 500 that stores information about the golf club, including information about the club identified by the club detection unit.

The cover unit 130 includes various types of signs that can be identified, such as a simple figure, a difference in reflectance or color, and the club detector 140 identifies a cover provided in the cover unit 130 by using an image recognition device such as a camera. Identify the club your golfer is using. In the second embodiment, the cover unit 130 does not contain the date of the club but only the cover plate for identifying the club, and the club detection unit 140 detects the identification of the club data stored in the database 500. It is a way to withdraw and use the information about the club.

The second embodiment as described above has the advantage of identifying the club in a very simple way that the golfer can directly attach the cover portion 130 for his or her club only need to attach a simple cover while rounding the golfer There is no interference at all, and the manufacturing cost is very low.

The sensing unit 200 senses the trajectory of the ball hit by the golfer and the trajectory of the club. The ball trajectory measures the physical quantity that can know the trajectory of the ball, including the left and right and up and down directions, and the speed of the ball. The club trajectory detects the club trajectory by sensing the club swing trajectory and the direction of the club face. The result sensed by the sensing unit 200 is mapped on the golf course to calculate the trajectory of the ball to be simulated in the calculation unit 300. In the actual field, the material of the club head and the length of the club shaft and the loft of each club The trajectory of the ball is different and the left and right and backspins of the ball are changed according to the loft, so the distance of the ball is rolled from side to side or when it lands on the ground.

Conventionally, the ball trajectory and the club trajectory are estimated without detailed information about the club, and the ball trajectory is roughly calculated by applying the data accordingly. If not, there was a problem of simulating a trajectory different from the actual one, but the calculation unit 300 of the present invention can accurately identify the club used by the golfer by using the club identification unit 100, and the trajectory of the ball to be simulated accordingly. It is possible to apply the club's spec data used to calculate the accuracy of the ball's trajectory and to determine if the golfer has not hit the ball accurately. There is an advantage to this.

The calculation unit 300 calculates the trajectory of the ball to be simulated using the ball sensed by the sensing unit 200 and the club identification unit 100 and the club trajectory and the identified club data.

The result calculated by the calculator 300 is displayed to the golfer through the display device 400 and the ball hit along the trajectory of the ball calculated in the simulated golf course is reproduced.
