Description

GOLF FIELD GUIDE SYSTEM AND TAG TERMINAL AND HOLE CUP FOR IT}

The present invention relates to a golf course tag terminal and a golf course guidance system including the same, which is carried by a golf course user and informs the user of the position information of the hole and the cup.

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.

The distance, azimuth, altitude, or major distance between the hole cup and the golf space by using a GPS receiver or using a mobile phone service in the "distance, azimuth and altitude measuring device using a mobile phone" of Korean Patent No. 0454329 (published 2004.9.14) Techniques for measuring distance, azimuth and altitude between 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.

Further, in the "golf distance measuring system and measuring method" of Patent No. 2003-0068447 (filed Sep. 21, 2003), a predetermined distance confirmation signal is transmitted to the outside, and a signal transmitted from the outside is received to a predetermined point from the golf ball. The portable terminal for calculating the distance and the direction (direction) to the display and the calculated distance and direction, and at least two or more spaced apart from each other at a predetermined point of the golf course and the predetermined signal to the portable terminal by the distance confirmation signal The technique of accurately measuring the distance between the golf ball and the hole cup or the main point, and the distance and angle (direction) from the relative point, by using a transmitting antenna, and displaying the measured distance numerically .

However, these two techniques incur the inconvenience that the user must have separate equipment.

The present invention is to provide a golf course guide system or RF tag terminal applied thereto that can be configured at a low cost while providing convenience to the user.

RF tag terminal.

Golf tag terminal according to another embodiment of the present invention, the opening means for opening and closing the external lock device; An RF antenna for receiving an external reference RF signal; A position determination unit determining a distance or a direction from the reference RF signal to a user and a hole cup; And notification means for informing the user of the determined distance and / or direction.

The hole cup according to another embodiment of the present invention, the frame is formed with a seat to which the golf ball can be seated; An RF antenna installed at an entrance part of the seating part of the frame and emitting a reference RF signal for distance measurement to the outside; And a control module for supplying control and power for the emission of the reference RF signal.

When implementing the golf course guide system of the present invention according to the above configuration, there is an advantage that gives the golf course user the convenience of the game progress.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows an overall configuration of a golf course guide system according to the present invention.

The illustrated golf course guidance system includes at least two beacon devices 100-1 and 100-2 for emitting a first reference RF signal for position determination; A hole cup 200 emitting a second reference RF signal for distance determination; And determine a distance and / or direction with respect to the hole cup 200 from the received first reference RF signal and notify a user, and more accurately with the hole cup 200 from the received second reference RF signal. RF tag terminal 400 for notifying the user of the distance.

In addition, the golf course guide system may further include a T-zone device 600 for emitting a third reference signal for notifying the hole number, in this case, the RF tag terminal 400, the received third reference The hole number currently located can be determined from the signal and notified to the user.

The beacon devices 100-1 and 100-2 may be implemented as a transmission module that periodically emits the first reference RF signal, and the first reference RF signal in a wider range (eg, the entire golf course). In order to emit the light, a relatively bulky antenna may be provided. The first reference RF signal may carry identification symbols and emission times of the beacon devices 100-1 and 100-2 emitted.

The RF tag terminal 400 has information about the position of the beacon devices, and emits the beacon device 100-from the time difference between the emission time and the received time on the received first reference RF signal. 1, 100-2) and the distance between the RF tag terminal 400 can be determined. In the same manner, the RF tag terminal 400 may determine the distance between the at least two beacon devices 100-1 and 100-2 that know the location, and the determined two distances and the beacon device 100. From the positions of -1 and 100-2, the position of the RF tag terminal 400 may be determined by applying a triangulation method.

On the other hand, in another implementation, the RF tag terminal emits a response signal to the first reference RF signal, and the RF from the difference between the time when the beacon devices receive the response signal and the time when the first reference RF signal is emitted. The distance of the tag terminal can be determined. In this case, a time difference between the time at which the response signal is received and the time at which the first reference RF signal is emitted may be obtained by the beacon devices and transmitted to the RF tag terminal.

Meanwhile, in another implementation, the RF tag terminal may estimate a distance from the beacon apparatus from the reception strength RSSI of the first reference signal.

The RF tag terminal 400 has the position information on the hole cup 200, the RF tag terminal 400 from the position of its own and the position of the hole cup 200 determined in the above-described process. The distance and the direction from the user who carried the hole to the hole cup 200 are determined. Thereafter, the RF tag terminal 400 notifies the user of the final determined distance and direction to the hole cup 200 by visual and / or audio means.

The hole cup 200 may include an antenna or an RF communication module for emitting the second reference RF signal. The second reference RF signal may carry an emission time. In this case, the RF tag terminal 400 includes the hole cup 200 from a time difference (or a difference between the response signal or the reception intensity) of the emission time and the received time on the received second reference RF signal. And the distance between the RF tag terminal 400 may be determined. Of course, although the distance between the hole cup 200 and the RF tag terminal 400 can be determined using the first reference RF signal, beacon devices relatively far from the RF tag terminal 400 ( Since 100-1 and 100-2) are the reference, the error is relatively large. On the other hand, the distance from the hole cup 200 determined using the second reference RF signal emitted from the hole cup 200 is relatively small, and thus a more accurate distance determination is made. This helps in notifying the user of accurate distance information when putting.

The third reference RF signal emitted from the T-zone device 600 has a T-zone near the start point of each hole of the golf course as the emission area. The number of the corresponding hole may be carried in the third reference RF signal. When the user is located in the T-zone and the RF tag terminal 400 is located in the emission area of the third reference RF signal, the hole number carried in the received third reference RF signal is visual and / or audio means to the user. Can be notified.

Alternatively, when the RF tag terminal 400 is located in the emission area of the third reference RF signal, the hole cup of the hole number of the hole number of the received third reference RF signal is displayed on the position of the hole cup of the current hole recorded in the internal storage unit. Update to a location of 200). This helps the RF tag terminal 400 accurately identify the number of holes currently playing. In a real game, if the user grasps the number of the playing hole only by the user's current position with an out of bound (OB), an error may occur, and thus, by using the third reference RF signal as described above, this may be prevented. .

The T-zone device 600 may include an RF antenna and a communication module for emitting an RF signal.
