Description

Distance Indicator System for Golf {Distance Indicator System for Golf}

The present invention relates to a distance measuring device. More specifically, it is an improvement to the golf rangefinder that allows you to see how far the ball is from the hole cup (or the main point).

The origin of the history of modern golf begins with Queen Mary of Scotland in the mid-16th century.

Since then, golf has been loved primarily by the British imperial and aristocratic sports, and until the end of the 19th century, the ball called "Gutta Percha" has been mass-produced and spread to many countries.

The game of golf is played on a course of 18 holes, where you hit the first stroke in the teeing ground of each hole and put it into the hole cup on the green to make a hole out.

The distance between the golf ball and the hole cup or the main point during the golf game is important, because it depends only on the senses of the person, there is a problem that can not measure the exact distance. Recently, in order to provide convenience to golfers, a technology that can be viewed as a portable receiver by measuring the distance between the hole and the golfer by a wireless communication method has been disclosed, but has a disadvantage in that accuracy is reduced and errors due to crosstalk are generated.

Therefore, an object of the present invention is to solve the above problems, to determine the distance to the golf ball and the hole cup or the main point and display the number by a golfer distance measuring device that can determine the exact distance shot To provide.

Hereinafter, the operation of the golf distance measuring apparatus according to the present invention will be described in detail with reference to FIGS. 1 and 2 as follows.

First, A, B, B, and P are four golfers in the fifth hole, and the soldiers are each equipped with a portable receiver 100, and the transmitter 200 is installed near the fifth hole green or the top of the fifth hole cup flagpole. .

In this state, if the A is selected by the hole selection switch (not shown) of the operation panel 102 to check the distance between the current position and the green or flagpole, the receiver microcomputer 111 displays the display device ( Display “5” in 110 to indicate the hole selected by A. Here, when the receiver microcomputer 111 operates the hole selection switch of the operation panel 102, the numbers corresponding to the holes are sequentially displayed by increasing or decreasing the numbers sequentially while displaying the first " 1 ". .

When the user again operates the execution switch (not shown) of the operation panel 102 to transmit the distance calculation command, the receiver microcomputer 111 controls the receiver encryptor 103 and the receiver frequency generator 104. While outputting the control signal, a reference pulse signal corresponding to the fifth hole (for example, a pulse signal having five consecutive pulses of a predetermined type) is generated and output to the receiver encryptor 103. The receiver encryptor 103 then inserts the unique ID (or serial number) of the portable receiver possessed by the user into the reference pulse signal, for example, "1111" and encrypts it according to a preset method. Here, the reason for inserting the unique ID is to block duplicate reception of the signal from the bottle, the definition portable receiver 100.

On the other hand, the receiver microcomputer 111 controls the modulator 105 for the receiver to convert the transmission frequency output from the receiver frequency generator 104 to the encrypted signal output from the receiver encryptor 103 in the receiver modulator 105. To be modulated into a wireless signal. Herein, the wireless signal may be AM, FM, ultrasound, laser, light, and the like, and most preferably, AM is used due to the nature of the golf course.

Then, the radio-free signal modulated by the receiver modulator 105 is transmitted to the transmitter 200 through the receiver transceiver 106.

When a wireless signal is received from the portable receiver 100 via the transmitter transceiver 202, the transmitter microcomputer 208 controls the transmitter demodulator 203 and the transmitter decoder 204 to demodulate and decode the wireless signal. do. Therefore, the extracted reference pulse signal is used to check whether the corresponding hole, that is, when the transmitter 200 is located in the fifth hole, the fifth reference hole generates a distance reference pulse signal. Here, the reason why the transmitter microcomputer 208 compares the reference pulse signal among the signals transmitted from the portable receiver 100 is that the transmitter installed in the hole 7 receives the radio signal when the holes 5 and 7 are adjacent to each other. This is to prevent the distance information from the transmitter of the seventh hole to the portable receiver 100 in advance.

The unique ID included in the decrypted signal is compared. Thus, the unique ID is the same, that is, the unique ID of the portable receiver "1111" and the unique ID transmitted from the transmitter, that is, "1111", are compared, and if they match, the distance calculator 109 applies a distance reference pulse signal to the distance calculator. Calculate the distance from the transmitter. Here, the distance calculator 109 calculates the distance from the transmitter 200 at the propagation speed using the difference of the received time of the radio signal returned from the transmitter 200 from the time transmitted from the portable receiver 100. Here, the distance calculator 109 changes the applied formula according to AM, FM, ultrasound, laser, light, and the like.

When the distance calculation is completed from the distance calculator 109, the receiver microcomputer 111 displays the display 110 through the display apparatus 110, that is, when the distance between the transmitter 200 and the portable receiver 100 is 110 meters, “110”. Display the number to let you know the distance and end all routines. Therefore, you can accurately check the distance from the hole cup while playing golf.

As described above, according to the golf distance measuring device according to the present invention, the distance between the golf ball and the hole cup or the main point is identified and displayed as a number so that the person who takes the shot can determine the correct distance. It can be a great help.
