It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.

First, FIG. 1 shows a configuration diagram of a golf simulation system 1000 according to a preferred embodiment of the present invention.

1, the golf simulation system 1000 includes a game server 100 and a golf simulation apparatus 200 according to a preferred embodiment of the present invention.

In addition, the game server 100 can acquire weather information in real time from a weather server WS that provides weather information and the location of a weather observation point where an AWS (Automated Weather Station) is installed. For reference, there are about 600 AWS installed in Korea, and the average distance between each observation point is about 10 km. In addition, the weather server WS provides latitude, longitude, wind direction, wind speed, temperature, humidity, and precipitation information of each observation point.

FIG. 2 shows a configuration diagram of a golf simulation apparatus 200 according to a preferred embodiment of the present invention.

However, the golf course information storage unit 210 may be implemented as a configuration of the game server 100 instead of the golf simulation apparatus 200. [

The selection unit 220 receives information for selecting one golf course among a plurality of golf courses stored in the golf course information storage unit 210. The input to the selection unit 220 may allow the user to select one of a plurality of golf courses presented on the screen through the input device or allow the user to implement the golf course name by searching or inputting the golf course name through the input device.

Specifically, the weather observation point closest to the golf course input to the selection unit 220 can be implemented by calculating a distance value between the latitude and longitude information of the golf course input to the selection unit 220.

For example, the latitude and longitude information of the golf course inputted to the selection unit 220 is (a1, b1), the latitude and longitude information at the weather observation point P1 is (a2, b2), and the weather observation point P2 Let the latitude and longitude information at (a3, b3) be.

Further, the distance m2 between (a1, b1) and (a3, b3) can be calculated by the following equation (2).

If m1 is smaller than m2, the weather observation point P1 becomes the weather observation point located closest to the golf course entered in the selection unit 220. [

When the selector 220 receives the weather information desired by the weather information acquisition unit 230, the weather information acquisition unit 230 receives the weather information of the weather observation point closest to the input golf course, Weather information that is closest to the weather information can be presented.

Specifically, the weather information obtained at the first observation time A1 of the weather observation point closest to the golf course is referred to as (T1, H1, D1, V1), and at the second observation time A2 (T2, H2, D2, V2) of the obtained weather information. When the range of the weather information is (Tmax-Tmin, Hmax-Hmin, Dmax-Dmin, Vmax-Vmin) and the inputted weather information is set to (T3, H3, D3, V3)

The weather information that is the closest to the weather information input by the selection unit 220 is obtained by the weather information obtaining unit 230. The weather information obtaining unit 230 obtains the weights w1 and w2 in the ratio of the difference between the time point of the weather information and the input weather information, w2, w3, w4), and obtaining the weather information at a point where the sum of the absolute values is the smallest.

That is, the sum S1 of the absolute values at the first observation time A1 of the weather observation point can be calculated as the following equation (3).

In addition, the sum S2 of the absolute values at the second observed time A2 of the meteorological observation point can be calculated as shown in the following equation (4).

If s1 is smaller than s2, the weather information obtaining unit 230 finally obtains the weather information (T1, H1, D1, V1) obtained at the first observation time A1 of the weather station.
