In addition, the ultrasonic sensor can not only detect the moving speed of the golf club head, but also measure the minimum distance between the lower end of the golf club and the sensing unit 210. The ultrasonic sensor senses the proximity of the object by recognizing that the ultrasonic wave is reflected by touching the object. When the ultrasonic wave is reflected by the moving object, the speed of the moving object can be grasped, and the distance between the object and the sensor can also be grasped. .

The sensing unit 210 is provided with a connector 214 inserted into a groove formed at the bottom of the mobile device 270, and the connector 214 is formed to protrude from the side of the sensing unit 210 and is connected to the mobile device through the connector 214.

The control unit 240 may be formed of an application installed on the mobile device 270, that is, software. In addition, the control unit 240 may be made of software installed in the sensing unit 210. The control unit 240 is a display module 241 for displaying a target image on the screen of the mobile device 270 and a hitting analysis module for determining whether an accurate hit has been made based on information transmitted from the sensing unit 210 ( 242), a swing speed calculation module 243 for calculating the moving speed of the golf club, and a flight distance calculation module 244 for deriving the flying distance of the golf ball due to the swing.

The display module 241 may display a virtual golf ball image on the screen of the mobile device, and accordingly, the user may recognize an accurate hitting point and perform swing practice.

Conventional swing practice device measures the swing with a gyro sensor, an acceleration sensor, etc. installed on the golf club, but it is difficult to accurately swing practice because it swings in the air without specifying the location of the golf ball. In addition, in the case of hitting an actual golf ball, there is a limitation in place because it must be moved to a golf driving range or a golf course.

However, according to this embodiment, since a virtual golf ball image is provided on the screen of the mobile device 170, the user can set an accurate hitting position. Meanwhile, the hitting analysis module 242 determines whether an accurate hitting has been made based on the information transmitted from the sensing unit 210, and the hitting analysis module 242 has a minimum distance between the bottom of the golf club and the sensing unit 210. Calculate the distance between the bottom of the golf club and the ground from the center of the golf ball image. Accordingly, it can be determined whether or not the golf club hit the center of the golf ball in the height direction. The hitting analysis module 242 according to the present embodiment determines only the hitting accuracy of height “?*, but not the lateral hitting accuracy.

Meanwhile, the swing speed calculation module 243 may calculate the moving speed of the golf club by substituting the difference between the transmission and reception time of the ultrasonic waves sensed by the sensor 212 into the Doppler effect. The flying distance calculation module 244 calculates a rough flying distance based on the information derived from the hitting analysis module 242 and the swing speed calculation module 243. The behavior of the golf ball moving when the golf club hits the upper portion of the golf ball, the lower portion, the center, or the excessive lower portion is well known, and the distance calculation module 244 uses such data. The distance can be calculated in proportion to the swing speed.

The control unit 240 may calculate such a hitting position, swing speed, and flying distance and display it on the screen of the mobile device. In addition, the control unit 240 may store the number of swing exercises performed by the user and display it on the mobile device 270.
