Screen golf system capable of displaying a ball striking status and a method therefor

Abstract

A screen golf system is provided, which includes: a strike position sensor placed on a ground where the golf ball is placed and configured to sense a ground strike position when the golf club hits the golf ball and a ground near the golf ball and to output the sensed ground strike position in a form of a ground strike position signal; a strike force sensor configured to sense ground strike force when the golf club hits the golf ball and the ground near the golf ball and to output the sensed ground strike force in a form of a ground strike force signal; and an output device configured to receive the ground strike position signal and the ground strike force signal and to output a striking state, including the ground strike position and ground strike force of the golf club.

1 . A screen golf system having a striking state output function and providing a speed, flying angle, flying direction, and track of a golf ball when the golf ball hit by a golf club flies and hits a screen, the screen golf system comprising:

         2 . The screen golf system according to  claim 1 , wherein the strike position sensor comprises an impact prevention plate for absorbing or preventing an ground impact generated when the golf club hits the golf ball and the ground near the golf ball. 
     
     
         3 . The screen golf system according to  claim 1 , wherein one or more sensors for sensing the ground strike position according to the hit of the golf club arc disposed in the strike position sensor at constant intervals. 
     
     
         4 . The screen golf system according to  claim 1 , wherein the output device comprises one or more specific output units for outputting one or more ground strike positions. 
     
     
         5 . The screen golf system according to  claim 4 , wherein the specific output unit comprises an LED or a lamp. 
     
     
         6 . The screen golf system according to  claim 4 , wherein the output device outputs the ground strike force at different colors depending on the striking force through the one or more specific output units. 
     
     
         7 . The screen golf system according to  claim 1 , wherein the output device comprises one or more specific output units for outputting the ground strike force stepwise according to a degree of the striking force. 
     
     
         8 . The screen golf system according to  claim 1 , further comprising an amp board for amplifying the ground strike position signal outputted from the strike position sensor and the ground strike force signal outputted from the strike force sensor and transferring the amplified signals to the output device. 
     
     
         9 . The screen golf system according to  claim 1 , further comprising a main computer for receiving the ground strike position signal outputted from the strike position sensor and the ground strike force signal outputted from the strike force sensor, processing the received signals into digital data, and storing the digital data or transferring the digital data to the output device so that the ground strike position and the ground strike force are outputted. 
     
     
         10 . The screen golf system according to  claim 9 , wherein the main computer receives information about the golf player, matches the ground strike position and ground strike force, generated whenever the golf player performs striking by using the golf club, with the information about the golf player, accumulates and stores pieces of the matched information, and subsequently provides the pieces of accumulated and stored information about striking states for the golf player at a request of the golf player. 
     
     
         11 . A method of displaying a striking state in a screen golf system using a strike position sensor and a strike force sensor when a golf player hits a golf ball by using a golf club, the method comprising the steps of:
 (a) transferring strike force according to the hit of the golf club against the golf ball and a ground near the golf ball, resulting from a swing motion of the golf player, to a strike position sensor and a strike force sensor;   (b) the strike position sensor and the strike force sensor generating a ground strike position signal and a ground strike force signal of the golf club;   (c) transferring the generated ground strike position signal and the generated ground strike force signal to an output device; and   (d) the output device outputting a ground strike position and a ground strike force of the golf club.   
     
     
         12 . The method ac cording to  claim 11 , wherein the step (c) includes a main computer processing the generated ground strike position signal and the generated ground strike force signal into digital data and storing the digital data or transferring the digital data to the output device. 
     
     
         13 . The method according to  claim 12 , wherein the main computer receives information about the golf player, matches the generated ground strike position and ground strike force with the information about the golf player, accumulates and stores pieces of the matched information, and subsequently provides the pieces of accumulated and stored information about striking states for the golf player at a request of the golf player. 
     
     
         14 . The screen golf system according to  claim 2 , wherein one or more sensors for sensing the ground strike position according to the hit of the golf club are disposed in the strike position sensor at constant intervals.
