Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention receives a radio wave from a GPS (Global Positioning System) satellite to measure the current position of a user, thereby measuring a golf distance to a green. Regarding the method.

[0002]

2. Description of the Related Art Conventional golf distance measuring methods include a simple measuring method using binoculars and a practical application method proposed by the present inventor.
No. 123130 “Golf distance measuring device” is used. The simple measurement method provides a reference object formed in a predetermined size on the green, by looking through the reference object with binoculars, the size of the reference object with a scale scaled on the binoculars and This is a method of reading the inclination angle and checking it with a conversion table to know the distance. In the method using the golf distance measuring device, a predetermined transmission frequency of each course is determined in advance, and the transmitter is mounted on a pin to be inserted into the cup of the green and the reception frequency can be received. Golfers always carry a bowl. When measuring the distance, turn on the power switch and set the course selection changeover switch to enable reception, and by pointing the receiver to the pin, check the value displayed on the display of the receiver. It is a method to know the remaining distance to the green.

SUMMARY OF THE INVENTION The conventional golf distance simple measuring method described above has a large variation in the measuring distance depending on the measuring method and the measuring position, and the pin cannot be seen if the falling position of the golf ball is bad. It may happen that the distance and direction of the pin to be used cannot be determined. Especially when fog occurred, the target pin could not be seen from anywhere and the binoculars could not be used, so measurement was impossible.

In the method using the golf distance measuring device, a predetermined transmission frequency of each course must be determined in advance, and the transmitter must be provided on a pin to be inserted into the cup of the green. Therefore, it is necessary to cooperate with the golf course.
In addition, maintenance and inspection of the device must be carried out regularly, and a receiver for the golfer to carry must be prepared, which causes a problem that the facility cost is increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the hole shown in FIG. First, (a) the hole distance inputting step of inputting the distance from the tee position (S) to the green to the portable receiver (1) will be explained. The golfer has a function as shown in FIG. Hold the portable receiver (1) and operate the operation button (16) to enter the numbers of the hole number "1" and the hole distance "360" and store it in the storage unit (15). Keep it. In addition, the input of the hole distance may be stored in the storage unit (15) in advance while watching the score card from the 1st hole to the 18th hole.

(B) The zero position confirming process using the tea position (S) as the start point will be described. Standing at the tea position (S), the operation button (16) of the portable receiver (1) is used to display the display unit. Change the display of (14) to "0". At this time, in the portable receiver (1), the radio wave from the GPS satellite (2) is G
By being received by the receiving unit (12) through the PS antenna (11), the current location can be confirmed without the user transmitting radio waves, and the confirmed position is referred to as a reference point, that is, a start point. The central processing unit (13) performs the processing so that

The detailed structure of the portable receiver (1) will be described. A GPS antenna (11) for receiving radio waves from a GPS satellite (2) and a receiver (12).
A central processing unit (13), a display unit (14), and a storage unit (1
5) and the operation button (16). To describe the GPS (Global Positioning System) in detail, a satellite (2) launched into space is used to receive radio waves from the satellite (2) without the user transmitting a signal. It is a system that can measure the latitude, longitude, altitude, moving speed, direction, etc. of the user's current location by using only. The structure of this GPS is the GPS antenna (1
1), a visual controller integrated with a GPS receiver (12) for detecting the current location, a 4-inch color liquid crystal screen (14), and operation buttons (16), and an input to the visual controller , A display processor which reads data from a CD-ROM (15) and creates a graphic screen of various information has been developed. As a way to use this, you can go to the destination while checking the current driving position by installing it in a car and looking at the map drawn on the color LCD screen (14). However, it is also possible to drive safely and efficiently.

C) A description will be given of the two-point distance measuring step in which the flight distance to the golf ball falling point (L) is measured using the GPS satellite (2). First, the golf ball falling point (L) ) Press the operation button (16) and turn on the power.
When the power is turned on, the radio waves from the GPS satellite (2) pass from the GPS antenna (11) through the receiving unit (12) to the central processing unit (1).
3) is entered, and the current position is calculated there and the distance from the tee position (S), for example, "210" is calculated and output. The value "210" is stored in the storage unit (15).
Is stored in.

D) The calculation step of subtracting the distance of the falling point (L) from the hole distance will be explained.
The number of the hole distance "360" of the first hole stored in 5) is read into the central processing unit (13), and "210" is subtracted from this "360" and the remainder until the green is reached. Distance, "1
50 "is derived.

E) Explaining the display process of calculating and displaying the remaining distance to the green, the derived "150"
Is displayed on the display unit (14) according to a command from the central processing unit (13). Therefore, the golfer can see the remaining distance by looking at "150" displayed on the display unit (14).

[0013]

According to the present invention, the golf distance is measured by receiving the radio wave from the GPS satellite (2) and the remaining distance is displayed by the button operation of the portable receiver (1). As in the simple measurement method, there is almost no variation in the measurement distance depending on the measurement method or the measurement position, and the measurement can be performed regardless of the position where the golf ball is dropped, and the measurement can be performed regardless of the weather.

Further, according to the present invention, the remaining distance to the green can be known only by carrying the portable receiver (1) capable of receiving the radio wave from the GPS satellite (2) personally. There is no need to cooperate with a golf course as in the conventional method using a distance measuring device for golf, and it is not necessary to regularly perform maintenance and inspection of the device. Moreover, it is extremely easy to operate, so it can be used easily.
