BACKGROUND ART Golf refers to a game in which a ball is hit with a golf club (club, hereinafter referred to as a club) and put into the hole in a stadium equipped with a hole, that is, a golf course. As described above, such golf is played on a golf course, and the rule is that the person with the fewest strokes before the ball enters the hole wins the game. Therefore, in order to win the game, you have to hit the ball with the correct distance and direction. However, many meteorological factors such as atmospheric pressure, humidity, and temperature affect the golf game. Here, although the wind has the greatest influence on the golf game, in general, the weather information provided by the Korea Meteorological Administration is in units of 1 km, and when it is applied to a golf course, it is difficult to provide meaningful wind information. Therefore, the electronic caddy service that reflects the real-time wind information only displaying the current golf course and the remaining distance to the hole is not currently provided, so there is a limit to improving the performance.

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

1 is a view showing the configuration of an electronic caddy-type golf assistance system according to the present invention.

Referring to FIG. 1 , the electronic caddy type golf assistance system according to an embodiment of the present invention is collected by a weather measurement value collection device 100 for collecting weather measurement values of a golf course, and the weather measurement value collection device 100 . It includes a weather modeling device 200 for calculating meteorological information based on the measured meteorological value, and a golf assisting device 300 for receiving and displaying the weather information calculated by the weather modeling device 200 .

The meteorological measurement value collecting device 100 is for collecting meteorological measurement values for calculating the weather information of the golf course, and may be installed in 8 directions or 4 directions along the periphery of the golf course. The meteorological measurement value collection device 100 may be implemented by installing a pole-type tower having a length of 30 to 40 meters. However, the present invention is not limited thereto, and the existing facilities such as a lighting tower or a golf tournament relay tower installed in the past may be used without additional installation of the above-described tower, but may be installed at intervals of approximately 10 meters. The installed meteorological measurement value collecting apparatus 100 may collect meteorological measurement values including location, temperature, wind direction, wind speed, and altitude.

In addition, in this embodiment, the meteorological measurement value collection device 100 may include an Internet of Things (IoT), a beacon, or a wire drone weather sensor, and is optimized in consideration of scalability and maintenance efficiency. It can be installed at the observation point of the golf course with the optimum observation density considering the observation factors for each altitude.

The meteorological modeling apparatus 200 may calculate meteorological information by using the meteorological measurement values collected by the meteorological measurement value collecting apparatus 100 as input values. To this end, the meteorological modeling apparatus 200 includes a meteorological measurement value receiving module 210 for receiving the meteorological measurement values collected by the meteorological measurement value collecting device 100 , and the meteorological measurement received from the meteorological measurement value receiving module 210 . A weather information generation module 220 that generates weather information with a value, a caddy information generation module that generates caddy information including distance prediction information and club selection information based on the weather information generated by the weather information generation module 220 (230) may be included.

The meteorological measurement value receiving module 210 may receive the meteorological measurement values collected by the meteorological measurement value collecting device 100 . The weather measurement value receiving module 210 may be a communication module. Moreover, the above-described meteorological measurement value collection device 100 may also be provided with a communication module for transmitting the collected weather measurement values to the weather modeling device 200, and the golf assistance device 300 to be described later may also be provided with a communication module. can

The weather information generating module 220 may generate weather information based on the meteorological measurement value received from the meteorological measurement value receiving module 210 . Here, the meteorological measurement value includes temperature, humidity, wind direction, wind speed, atmospheric pressure, and the like, and may also include a location where temperature, humidity, wind direction, wind speed, and atmospheric pressure are measured. The meteorological information generation module 220 includes a first modeling module 221 for modeling a computational fluid dynamics model capable of simulating the flow and diffusion of a fluid, and a second modeling module 221 for modeling a mesoscale weather model capable of decomposing local circulation. It may include a modeling module 223 and a wind information generation module 225 that generates wind information using a joint model of a computational fluid dynamics model and a mesoscale meteorological model.

Here, the meteorological information generation module 220 uses a joint model of a computational fluid dynamics model and a mesoscale meteorological model for more realistic detailed scale flow and diffusion simulation of meteorological conditions, and sets the inflow and outflow boundary conditions of the computational fluid dynamics model to mesoscale weather. It can be improved through the results of the model. At this time, since the mesoscale meteorological model can decompose local circulation such as sea and valley winds, it is possible to include spatial changes (horizontal and vertical changes in wind) in the boundary data of the computational fluid dynamics model provided by the mesoscale meteorological model. .

Such spatial change is known to have a significant effect on the diffusion of pollutants, etc. as well as the detailed-scale flow, but most computational fluid dynamics models have a limitation in considering only the fixed wind direction at the inflow and outflow boundary. Therefore, in order to numerically simulate more realistic detailed-scale flow and diffusion, it is necessary to improve the boundary conditions that can effectively reflect the effects of local circulation simulated by mesoscale meteorological models.

The meteorological information generation module 220 may add a bonding process so that the boundary conditions can be considered by changing the wind directions of the upper and lower layers at the inflow interface when the computational fluid dynamics model and the mesoscale weather model are joined. In addition, the meteorological information generating module 220 may process and extract the wind component and turbulent kinetic energy of the mesoscale weather model as boundary conditions. , the weather information generation module 220 may interpolate them horizontally and vertically to be used as initial input data of the computational fluid dynamics model.

In addition, the joint model of the computational fluid dynamics model and the mesoscale meteorological model shows excellent performance in numerical simulation of flow and diffusion around obstacles such as buildings, and has a wide range of applications, especially indoor air flow and air quality evaluation, building scale ( It is possible to evaluate the flow field and pollutant diffusion evaluation of urban canyons, single obstacles, etc.) and the urban scale flow field and pollutant diffusion evaluation. In addition, the joint model between the computational fluid dynamics model and the mesoscale model can be improved and more accurate atmospheric environment simulation can be performed through chemical module joining.

Since the occurrence of local meteorological phenomena occurs periodically in the actual atmosphere, the wind directions in the upper and lower layers of the atmosphere do not match or appear in the opposite direction very frequently. Therefore, in order to take into account local weather phenomena, it is necessary to improve boundary conditions so that changes in wind direction by altitude can be taken into account.

If only the data provided by the mesoscale model is used, there are cases where inflow and outflow occur simultaneously at one interface. Although there was a problem that it was difficult to accurately reflect the wind direction and wind speed changes included in the boundary data, in the present invention, the model was improved to enable inflow or outflow flows in multiple directions at one boundary surface. It has been improved so that it can be reflected.

In the present invention, in order to build a one-way joint model between the computational fluid dynamics model and the mesoscale weather model, the meteorological information generation module 220 uses the three-way wind components (U, V, W) and turbulent kinetic energy (Turbulent) of the mesoscale meteorological model result. Kinetic Energy, TKE) can be used for data processing and extraction.

For example, the meteorological information generating module 220 may extract a wind component and a turbulent kinetic energy component from the center of the observation point through latitude and longitude coordinates of the target area. At this time, since the extracted wind components and turbulent kinetic energy by altitude do not have as dense information as the horizontal and vertical grids of the computational fluid dynamics model, an interpolation process is required. In addition, since the data extracted from the mesoscale meteorological model is about 1 km resolution data, it is possible to generate data for each grid by vertically and horizontally interpolating to fit the grid (10 m horizontally, 5 m vertical) of the computational fluid dynamics model. Here, the wind component and turbulent kinetic energy of a mesoscale meteorological model of a total of 9 points including the observation point and the surrounding area were interpolated and used as initial input data.

2 shows the lattice structures of the computational fluid dynamics model and the mesoscale weather model, (a) interpolating the wind component and turbulent kinetic energy data at the grid points of the mesoscale meteorological model to the grid points of the computational fluid dynamics model. method is modeled.

Wind components by time and altitude extracted from mesoscale meteorological models may have different directions in the upper and lower layers. In addition, the interpolated wind component and turbulent kinetic energy can be used as initial values of the model by completing the vertical structure for each point in the computational fluid dynamics model drawing.

Again, referring to FIG. 1 , the wind information generating module 225 generates wind information of a desired target area. To this end, the wind information generation module 225 includes a wind information altitude elevation module. In addition, the wind information generation module 225 to be described later is a practical quantitative wind model of the present invention.

3 is an exemplary view of generating wind and precipitation in Jeju Island with a resolution of 1 km in the electronic caddy type golf assistance system according to the present invention.

The wind information altitude elevation module raises the wind information generated through the wind information generation module 225, that is, sea level air pressure wind data interpolated to a desired grid size, to the detailed topographical altitude, that is, to the actual altitude of the region where wind information is to be generated. make it

This is that the present invention is to generate wind information in an unobserved area using the observation data substantially observed by the first meteorological value collecting device 100 and the second meteorological value collecting device 100, and the first Since the altitude was lowered to make the altitudes of the meteorological measurement value collecting device 100 and the second meteorological value collecting device 100 the same, the altitude of the unobserved area is also lowered. Therefore, in order to accurately generate wind information of the unobserved area, the unobserved area is raised to the actual altitude, that is, the detailed terrain altitude.

In addition, according to this, wind information may be generated as shown in FIG. 3 . Of course, FIG. 3 shows that wind information is generated with a resolution of 1 km, and the present invention can calculate a detailed wind field on a local scale of 1 m to 30 m. In addition, in order to increase the resolution of the detailed local-scale wind field, it is preferable to calculate a high-precision GIS with a drone and use it as an input value of the meteorological modeling apparatus 200 . Meanwhile, the wind information generation configuration described above is only an example, and the present invention may generate wind information in various ways.

Again, referring to FIG. 1 , the caddy information generation module 230 may generate caddy information based on the weather information generated by the weather information generation module 220 . Here, the caddy information includes wind information, flying distance information, club selection information, and swing time information. 232), and a swing timing information generating module 233 . Here, the wind information may use wind information generated by the above-described weather information generating module 220 .

The flying distance prediction information generating module 231 may generate the flying distance prediction information based on the wind direction and the wind speed and the distance information for each club of the user received by the flying distance information input module 320 of the golf assisting device 300 . This can be created by applying the wind direction and wind speed to the distance information of the currently selected club. For example, if the currently selected club is a 7 iron and the distance information for the 7 iron is 150 yards, 150 yards may be the distance prediction information when there is no wind. Here, in the case of a headwind, the flying distance prediction information is reduced, and the stronger the intensity of the headwind, the more it decreases. In addition, in the case of a tail wind, the flying distance prediction information may increase, and may further increase as the strength of the tail wind increases. Of course, the flying distance prediction information generating module 231 may also generate flying distance prediction information according to the wind direction and wind speed for each altitude.

The club selection information generating module 232 generates club selection information to be provided to the user according to the flying distance prediction information generated by the flying distance prediction information generating module 231 . For example, when the distance to the hole is 130 yards and the headwind is weak, the club selection information may be generated as an 8-iron, which is a club corresponding to 130 yards in the distance prediction information. Of course, it is meaningless to generate the club selection information when the wind rapidly changes, and the club selection information generating module 232 preferably generates the club selection information when the wind direction change and wind speed change within a predetermined range are seen.

The swing point information generation module 233 may generate swing point information based on wind information included in the caddy information. Here, the generation of the swing time information may be generated by looking at the time when the wind blows at a wind speed within a predetermined range to the extent that there is basically no wind or close to no wind as the swing time point. However, the present invention is not limited thereto. For example, a swing time may be input from the user, which may be when there is no wind or a wind close to no wind, as described above. Also, it may be when a headwind or a headwind blows while looking toward the hole. It is preferable that the swing timing information generation module 233 immediately transmits the swing timing information to the golf assistance device 300 when the swing timing information is generated, and the golf assistance device 300 immediately displays it. Here, when swinging with a sand wedge, the trajectory of the ball is high, and when swinging with an iron, the trajectory of the ball is lower than that of the sand wedge. Therefore, when the user swings with a sand wedge, swing time information is generated based on the wind at an altitude above a certain height, and when the user swings with an iron, swing time information can be generated based on the wind at an altitude below a certain height. have. According to the club selected by the user, it is possible to automatically generate swing time information using wind information in a certain height range. Of course, the above-described predetermined height range may be manually changed by the user. For example, even if you use irons, you can hit a high trajectory shot.

The golf assistance device 300 provides the caddy information generated by the weather modeling device 200 to the user. The golf auxiliary device 300 may be implemented in various forms, such as a wrist watch type, a telescopic type, a smartphone type, and an attachment type. In addition, the golf auxiliary device 300 includes a location information generation module 310 for generating location information, a distance information input module 320 for receiving distance information for each club from a user, and a club selection for receiving a current club input from the user. The module 330 includes a caddy information display module 340 for displaying the caddy information generated by the weather modeling apparatus 200 .

The location information generating module 310 generates location information using a Global Navigation Satellite System (GNSS) or the like. In general, since the golf assisting device 300 is possessed by the user, the location information generating module 310 generates the user's location information by generating the location information of the golf assisting device 300 . In addition, the location information generating module 310 transmits the generated location information to the weather modeling apparatus 200 .

The flying distance information input module 320 receives distance information for each club from the user. That is, the user inputs the distance information for each club by using a touch screen or a button provided in the golf assisting device 300 .

The club selection module 330 receives a current club to be used from the user. That is, the user selects a club to be currently used by the user using a touch screen or a button, and the selected club is used to generate caddy information.

The caddy information display module 340 displays caddy information generated by the weather modeling apparatus 200 . To this end, the caddy information display module 340 may display the caddy information visually through a display or by voice through a speaker. Of course, it is also possible to display the swing timing by vibration.

On the other hand, the golf assisting device 300 according to the present invention can recognize the information providing range, that is, when the golf assisting device 300 is located within a predetermined range in the meteorological measurement value collecting device 100, the weather modeling device 200 can recognize it. have. Here, the recognition of the golf assisting device 300 may be made by recognizing a different unique number for each golf assisting device 300 . Of course, the present invention is not limited thereto, and the weather modeling device 200 receives and authenticates user information from the user, for example, a unique number of the golf auxiliary device 300, and then registers the ID and password received from the user. And, the golf assisting device 300 can be recognized by transmitting the ID and password received from the user to the weather modeling device 200 to be authenticated.

As described above, according to the present invention, it is possible to improve golf performance by providing local-scale three-dimensional wind information within a golf course.

The above description of the present invention is for illustration, and those of ordinary skill in the art to which the present invention pertains can understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. will be.
