The present invention relates to a golf distance measuring method using an RF-ID tag that can accurately measure the distance and direction between the golf ball and the hole cup using two antennas and a golf ball with an RF-ID tag installed in the golf course will be.

In general, golf is a sport in which a golf ball is put into a hole cup with the lowest possible stroke. Therefore, the golfer must accurately determine the distance between the golf ball and the hole cup in order to score better.

The distance between the golf ball and the hole cup is measured by referring to the distance indicator along the fairway at 50 or 100 yard intervals or the flagpoles placed on each hole cup. In this method, the golfer's sense is used to measure the distance between the golf ball and the hole cup, so the error occurrence rate is high and accurate distance calculation is difficult.

Location tracking techniques include the use of base stations and the use of satellites. The method of using a base station is a method of determining the location of a mobile device holder using a so-called trigonometry, and the method of using a satellite is generally called a global position system (GPS). The present invention is applied to the distance measuring system for golf.

U.S. Patent No. 6,104,337 (Patent Publication No. 2000.8.15) discloses a technique related to "golf rangefinder", wherein the distance between the golf player and the hole cup is measured by a wireless communication method using a microcomputer. Techniques for displaying distances on portable LCD displays have been described.

Recently, in order to provide convenience to golfers, a technique of measuring a distance between a golf ball and a hole cup by a wireless communication method and viewing the measured distance as a portable terminal of a golfer is used.

On the other hand, the applicant is equipped with a GPS receiver in the "distance, azimuth and altitude measuring device using a mobile phone" of the Republic of Korea Patent No. 0454329 (published 2004.9.14) or the distance, bearing of the hole cup and golf space using a mobile phone service Techniques for measuring altitude, distance, azimuth and altitude between major objects have been published. However, there is a problem in that the GPS antenna must be mounted on the mobile phone, and there is a problem that the device purchase cost is also high.

In addition, the applicant in the "golf distance measuring system and measurement method" of Patent No. 2003-0068447 (filed September 21, 2003) transmits a predetermined distance confirmation signal to the outside and receives a signal transmitted from the outside to the predetermined from the golf ball A portable terminal for calculating a distance and an angle (direction) to a point of the display and displaying the calculated distance and direction, and at least two spaced apart from each other at a predetermined point of the golf course and carrying a predetermined signal by a distance confirmation signal By using the antenna to transmit to each terminal by using the triangulation method to accurately measure the distance between the golf ball and the hole cup or the main point, and the distance and angle (direction) from the relative point before, and displays the measured distance numerically Presented.

However, these two techniques have the disadvantage of not accurately determining the position of the golf ball because the position of the golf ball is calculated based on the position of the portable terminal.

Accordingly, an object of the present invention is to use a golf ball with an RF-ID tag and two antennas installed in the golf course distance for golf using the RF-ID tag that can accurately measure the distance and direction between the golf ball and the hole cup In providing a measuring method.

In addition, another object of the present invention is to provide a golf distance measuring method using an RF-ID tag to enjoy a more lively game by tracking the movement path of the golf ball on the screen.

In order to achieve the above object, the present invention provides a golf ball with an RF-ID tag, a distance measuring server for calculating the distance from the golf ball to the selected hole cup, a first antenna installed at a predetermined place of the golf course, In the golf distance measuring method using a conventional RF-ID tag comprising a second antenna spaced apart from one antenna and installed in a predetermined place of the golf course,
