Description

Golf swing data measuring device with billboard {MEASURING APPARATUS HAVING ADVERTISING PLATE FOR SWING DATA OF THE GOLF CLUB HEAD}

The present invention relates to a golf swing data measuring device having a billboard, and in detail, it is possible to measure the swing speed of the golf club head and the flying range of the golf ball, and unconsciously advertises a predetermined advertisement before and after the swing of the golf practitioner. The present invention relates to a golf swing data measuring apparatus having a billboard that can be known naturally.

In general, golf sleeps and is a popular leisure sport known to the public compared to the past.

In order to enjoy such a golf game, a lot of hitting practice and field adaptation training are required due to the nature of the game, but the hitting practice in the city center where ordinary people live is limited in terms of spatial constraints, especially the position of the field for the general public to play golf directly. In practice, many restrictions are imposed on various conditions including field use conditions.

Therefore, in recent years, many golf driving ranges have been created in the city, providing a space where golfers can easily practice golf. Golf practice in such a golf driving range, for example, a swing practice of a golf club is performed by supplying a golf ball from a golf ball auto feeder to a batting mat covered with artificial turf, and repeatedly hitting the golf ball by the golf practitioner.

As described above, in the case of practicing golf under the same conditions as the actual golf course in a golf driving range, the golfer swings the golf club head because the distance at which the ball flows increases as the head speed at the impact moment when the club head hits the ball increases. Try to speed up. Also, the trend of modern golf is changing from technology golf to power golf. In other words, it is changing from a blow that is accurate but far away to a precise blow while far away.

Therefore, the golfer measures the swing speed to increase the swing speed. Conventionally, the golfer is composed of an analog swing speed measuring device that attaches a mechanically configured device to a golf club head using a gear, and an electronic circuit using an infrared receiver and an infrared transmitter. Optical swing speed measuring devices have been used.

However, among the conventional swing speed measuring devices, since the analog swing speed measuring device uses a mechanically configured device attached to the golf club head, the swing angle is different from the golf club used in practice. It does not provide accurate data.

In addition, the optical swing speed measuring device using the infrared receiver and the infrared transmitter should be input to the infrared receiver by reflecting the infrared rays output from the infrared transmitter, but the actual golf club head reflects the golf club head because it reflects directly If the angle is not correct, there is a lot of malfunction rate that the infrared receiver cannot detect the movement of the golf club head.

On the other hand, general golf equipment vendors sell online and offline products such as newspapers, magazines and the Internet to advertise various golf products such as golf clubs, golf bags, golf balls, golf shoes, golf gloves, putting practice mats and swing exercisers. Frequently use advertising media. However, the advertisement using the on and offline advertising media can not accurately grasp the target of the advertisement, can not accurately measure the exposure frequency of the advertising content, the short exposure time.

In order to overcome such a problem, recently, the advertisement contents are printed on the batter slats of the golf driving range described above, or a golfer's gaze is induced by hanging a banner with the advertising contents on the net of the driving range.

However, in the former case, when the practitioner hits the golf ball, the gaze of the practitioner is concentrated on the golf club head and the golf ball, and the eye movement naturally moves to the flying point of the golf ball as soon as the practitioner hits the golf ball. There is a problem that the attention to the content is inferior, and the advertisement contents cannot be selectively replaced because the advertisement contents are printed on the at-bat divider.

In the latter case, the player's gaze can be directed toward the net at the moment the player hits the golf ball, but the quality of the advertisement is degraded because there is no difference to focus the gaze, and the advertisement is contaminated by rain or wind. Problems occur.

The present invention has been conceived to improve the above problems, the magnetic field according to the swing operation of the golf club head using a magnetic sensor to provide accurate swing data of the golf club as well as to minimize the malfunction rate of the data measuring means It is an object of the present invention to provide a golf swing data measuring apparatus having a billboard that can measure the flight range of a golf ball based on the swing speed of the golf club head and the swing speed of the golf club head by detecting a change in the golf club head.

After the determination, if the intensity can be recognized as the magnetizable object 5, it is converted into a pulse signal and applied to the microcomputer 30.

In addition, when the golf club head is positioned at the second swing operating point 12 along the traveling direction 14 via the first swing operating point 11, the second magnetic sensor 20a is the first magnetic sensor 10a. It works the same as). That is, the second magnetic sensor 20a of the second magnetic sensor module 20 detects the magnetizable object 5 attached to the golf club head as a change in the magnetic field, thereby converting the analog electric signal to the second amplifier 20b. Is authorized. The second amplifier 20b receives the analog electrical signal output from the second magnetic sensor 20a, amplifies the signal in a direction of increasing the signal-to-noise ratio, and applies it to the second ADC 20c. The second ADC 20c receiving the amplified analog electrical signal converts the amplified analog electrical signal into a digital electrical signal and applies it to the second microprocessor 20d. After receiving the digital electrical signal, the second microprocessor 20d determines whether the strength of the digital electrical signal can be recognized as the magnetizable object 5 by comparing the setting value stored in the memory of the second microprocessor 20d. If the intensity can be recognized as the magnetizable object 5, it is converted into a pulse signal and applied to the microcomputer 30.
