It is a figure which shows the calculation result of the prediction play time of the golf cart which concerns on embodiment. It is a flowchart of the golf cart position management method concerning an embodiment.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the components, types, combinations, shapes, relative arrangements, and the like described in this embodiment are merely illustrative examples and not intended to limit the scope of the present invention only unless otherwise specified. .

FIG. 1 is a block diagram of a golf cart position management system using a golf cart position management apparatus according to an embodiment of the present invention.
The golf cart position management system is sent from a plurality of golf carts M (M1, M2,... Mn) equipped with communication means for transmitting position information and communication means mounted on each golf cart M. And a base station B that processes incoming position information.
There are a plurality of golf carts M, each of which includes a position detection unit 101 and a communication device 102.
The base station B includes a base station communication device 202 that communicates with the communication device 102 of each golf cart M, a golf cart location management device 201 that processes location information transmitted from each golf cart M, and each golf cart. And a display unit 203 for displaying the position of the cart M.

The position detecting unit 101 of the golf cart M may receive a signal from a satellite, for example, a GPS (Global Positioning System) or a position information signal from a beacon transmitter embedded in a cart road. Good.
As long as the communication device 102 of the golf cart M can transmit position information as data, any communication method may be used. Further, it may be a communication device dedicated to transmission.

  The base station communication device 202 of the base station B is a communication device that communicates with the communication device 102 of the golf cart, and receives position information transmitted from the golf cart M. A reception-only communication device may be used.

The golf cart position management device 201 of the base station B processes the position information when the position information is obtained from the golf cart M, and performs the process of estimating the position when the position information is not obtained.
Further, the golf cart position management device 201 outputs the result of processing the position information or the result of estimating the position to the display unit 203.

  The golf cart position management device 201 is a specific example of management means. For example, a CPU (Central Processing Unit) that performs arithmetic processing and the like, and a ROM (Read Only) in which arithmetic programs and data executed by the CPU are recorded. A microcomputer having a memory and a RAM (Random Access Memory) that temporarily stores processing data and the like is mainly configured. The CPU, ROM, and RAM are connected to each other by a data bus or the like.

  The display unit 203 is a liquid crystal display device, an organic or inorganic EL device, and the like, and displays the position of each golf cart. For example, the position of each golf cart is displayed on the hole layout diagram of the entire course. FIG. 3 is a schematic diagram of the hole layout of the entire course. Each hole is indicated by an ellipse, T indicates the tee ground, and G indicates the position of the green. The golf carts M (M1, M2, M3,... Mn) are displayed on the course based on the position information, and it is possible to grasp which golf cart is currently in which part of what number hole.

  In addition to overlaying the display on the hole layout diagram, as shown in FIG. 4, there is a cart for each hole, where the number of holes is in the table format for each hole, with the left side being the tee ground position and the right side being the green position. Or may be displayed. In FIG. 4, the distance of each hole may be displayed as a one-dimensional position such as how many yards from the tee ground in correspondence with the length of each hole in the table.

Further, when the exact position is not necessary, for example, the golf cart M5 of FIG. 3 is located slightly greener than the vicinity of the center of the long hole of the 6th par 5. Since it is a par 5 with a specified number of shots, it is a position where it is the third shot for a person with a certain skill. Therefore, as shown in the position of the golf cart M5 in FIG. 4, the hole is divided into a number obtained by subtracting 1 from the specified number of shots, and M5 is displayed in the third frame, so that the point of the third shot of the sixth hole It can be recognized that there is a golf cart M5 in the vicinity.
There are various display methods, but the display method does not matter. The time display for each golf cart described later can also be used as a similar display format.
Hereinafter, “hole” refers to an area including each tee ground to the green corresponding to the tee ground when there are holes from 1st to 18th, for example.

  The base station B is installed in, for example, a caddy master room of a club house. The golf course management manager who operates the base station B grasps the progress of each cart and manages it so as to play smoothly without delay.

  Because of the long play time, many golf courses start with the 9th hole and the 9th hole, start from the 1st hole and return to the clubhouse at the 9th hole. The layout is to return to the clubhouse in the hall.

  Therefore, the 1st and 10th tees and the 9th and 18th greens are relatively close to the clubhouse. In the 9 holes in the first half and the 9 holes in the second half, the 4th hole, 5th hole, 6th hole, 13th hole, 14th hole and 15th hole, which are the middle, are relatively far from the clubhouse. Often position.

  Therefore, after the golf cart M starts, the distance from the clubhouse becomes far away from the above-mentioned middle hole, and the distance from the clubhouse to the final hole (9th or 18th) after finishing the above-mentioned middle hole becomes the distance from the clubhouse. Gradually getting closer. For this reason, the electric field strength decreases in communication in the middle hall.

  Golf courses are not necessarily created in flat places, but in places such as mountains and hills. Depending on the course hole layout, there may be an area where communication between the communication device 102 of the golf cart M and the base station communication device 202 of the base station B is blocked by a mountain and cannot be communicated. In that case, since the position information cannot be transmitted to the base station B even if the position detection unit 101 of the golf cart M can detect the position, the base station B has a function of estimating the position of the golf cart M.

FIG. 2 is a block diagram of the golf cart position management apparatus 201 according to one embodiment of the present invention. The operation of the golf cart position management device according to one embodiment of the present invention will be described with reference to FIG.
When the golf cart M is an area where communication with the base station B is possible, the communication device 102 of the golf cart M transmits position information, and the base station communication device 202 receives the position information and manages the position information. Output to the device 201.
The position information obtained from the golf cart M is described as actual position information in order to distinguish it from the predicted position information described below.

  The actual position information is input to the golf cart position information processing unit 201b. The golf cart position information processing unit 201b compares predetermined hole layout information and actual position information, and outputs the display position information as a result thereof to the display unit 203.

The actual position information is input to the hole position specifying unit 201c.
The hole position specifying unit 201c specifies at which position of which hole the cart is located.
For example, it is specified which hit point of which hole.
If the actual position information sent is actual position information within a predetermined range of the tee ground regardless of the number of pars that is the prescribed number of holes in the hole, the predetermined position between the first hit point, the tee ground of the par 4 and the green If it is a range of 2 points, in the case of par 5, if it is a predetermined range between the 2nd point and the green, if it is a 3rd point, if it is the actual position information of a predetermined range around the green, The par 3 hole is the second hit point, the par 4 is the third hit point, and the par 5 is the fourth hit point.
If the actual position information of the tee ground of the 2nd hole, the 1st hit point of the 2nd hole, if the actual position information around the green of the 8th hole (assuming par 4), the 3rd hit point of the 8th hole It becomes. Since each hitting point indicates a position on the hole, the generic name is hereinafter referred to as a hole position. The position information in this hole is used as hole position information.
Since the actual position information is a single point, the hole position may be specified using a predetermined range in the course as a threshold value. Hereinafter, “hole” refers to an area including each tee ground to the green corresponding to the tee ground when there are holes from 1st to 18th, for example.

The golf cart hole position information specified by the hole position specifying unit 201c is output to the actual play time recording unit 201e, and the time when the hole position information is received is recorded together with the hole position information.
FIG. 5 is an example showing the contents recorded by the actual play time recording unit 201e. For each hole, an area for recording time by the number obtained by subtracting 1 from the number of pars is prepared, and the time when the actual position information is obtained is recorded.
In the example of FIG. 5, the set of golf carts M1 starts from the 1st hole at 8 o'clock, arrives at a predetermined range at the second hit point at 8:10, and enters a predetermined range around the green at 8:15. It is recorded that it arrived at the second hole at 8:20.
Therefore, when the actual position information is obtained, the progress of the golf cart is recorded in the actual play time recording unit 201e as needed.

  As described above, the distance between the club house in which the base station B is installed and the golf cart M is often longer in the middle hole, and the actual position information transmitted from the communication device 102 of the golf cart M is the distance. The base station B may not be able to receive the signal due to a decrease in signal field strength. Further, there are cases where the base station B cannot receive the actual position information because it is shielded by a mountain or the like. In that case, the time is not recorded in the actual play time recording unit 201e.

In order to operate efficiently, a golf course manager often determines a standard play time (standard play time) and asks the player to go around the course within that time. Generally, there are many places where 9 holes are 2 hours and 15 minutes, with an average of 15 minutes per hole. An example is shown in FIG.
However, the skills vary, and it often takes more than 20 minutes to start and finish the par 4 hole.
In general, it is considered that the lower the skill of golf, the longer it takes. Based on this assumption, even if actual position information cannot be obtained, it is possible to predict the future progress of the golf cart set from the last time when the actual position information was obtained and the standard play time. .

The standard play time table 201d stores the standard play time described above. The start time may be 0 hour and 0 minute and may be a relative time. It doesn't matter what unit you memorize.
The predicted play time calculation unit 201f reads the actual play time from the actual play time recording unit 201e, and calculates the future play time from the standard time table recorded in the standard play time table 201d.

The actual play time of the set of golf carts M1 shown in FIG.
In addition, since the time (start time) of the first hit point of the 1st hole or the 10th hole is often determined in advance by the golf course management manager, the start time may be used. It may be the time when the actual position information of the first hit point is obtained.
The golf cart M1 group started the 1st hole at 8:00, and the time indicated by the underline is the time when the latest actual position information was obtained. Thus, the time required for the first hole, that is, the actual play time of the first hole is 20 minutes.
Further, since the standard play time shown in FIG. 6 is 15 minutes, it means that it took 5 minutes more time.

As an example of calculating the predicted time, the ratio of the actual play time (actual play time minus start time) and the standard play time is used as a coefficient, and the subsequent time is calculated from the standard play time multiplied by the coefficient. Calculate the time. Since the standard play time was 15 minutes, it took 20 minutes, so dividing 20 by 15 yielded 1.333 ... and the standard play time was multiplied by this factor 1.333 ... The predicted time is calculated using the time as the predicted predicted play time for the set of golf carts M1. The coefficient may be calculated at the end of one hole, or the coefficient may be calculated as needed from the time when the actual position information of each hitting point is obtained.
The predicted play time and the hole position, which are the results calculated by the predicted play time calculation unit 201f, are output to the predicted position calculation unit 201g.

The predicted position calculation unit 201g calculates the time of the course position (predicted play time) after the time of the last detected actual position information based on the time calculated as the predicted play time 201f. The result is the time indicated by italic characters in FIG.
The predicted position calculation unit 201g obtains time information (not shown), and the golf cart M is positioned at the course position such as what number of holes and what hit point when the time coincides with the predicted play time. The predicted position information to be present is sent to the golf cart position information processing unit 201b.

The golf cart position information processing unit 201b outputs display position information to the display unit 203 based on the actual position information while the actual position information is obtained. However, display position information is generated and output to the display unit 203 based on the predicted position information output from the predicted position calculation unit 201g when the actual position information is not obtained and the predicted play time is reached.

  The golf cart position information processing unit 201b uses the last one of the actual position information or the predicted position information as the display position information, and displays the display information until the next actual position information or the predicted position information is obtained. maintain.

  When two pieces of position information input to the golf cart position information processing unit 201b are simultaneous, the actual position information may be given priority. Also, calculate the predicted play time again at the time when the actual position information was detected, and always calculate the time of each hitting point after the time when the actual position information was detected. If there is an area where golf cart M communication is possible, the position information becomes display position information, and the predicted time thereafter is recalculated. Therefore, the accuracy of the predicted play time increases as more actual position information is obtained, that is, as the play progresses.

FIG. 8 is a flowchart of a golf cart position management method according to an embodiment of the present invention.
The start time is specified in advance when the play is reserved, but the start time may slightly vary depending on the congestion status of the day, and the actual position information is obtained and set in a timely manner.
Start playing and proceed through the course. The golf cart M transmits actual position information in a timely manner.
If the actual position information has been obtained (Yes in step 302), the actual position is displayed based on the obtained actual position information (step 303).

On the basis of the obtained actual position information, the hall no. And its hole position are identified (step 304).
The hole position is determined by a golf course management operator such as each hitting point determined by the number of pars in each hole or a predetermined cart stop position, and the player often stops the golf cart during play. The position.

  Further, the position is specified and the time when the actual position information is obtained is recorded (step 305).

As described above, the manager of the golf course presets a standard play time (standard play time) as shown in FIG.
This shows how long it takes from the start to which position of a hole when a player with a certain skill plays.
Since the actual start time of the golf cart M is recorded, the time required up to that point is obtained as a difference depending on the time when the actual position information is actually obtained. Furthermore, from the above-mentioned standard play time and the difference, it can be determined from the ratio whether the progress of the golf cart is early or late.
Since the time taken for the standard play time using the ratio as a coefficient is the time that the set of golf carts M is expected to play, the time of arrival at the hole position after the predicted time (predicted play) Time) is calculated (step 306).

  If the actual position information is obtained, steps 302 to 306 are repeated. For example, when the display is displayed on the golf course map, the actual position is always displayed because the actual position information is obtained.

The actual position information is transmitted from each of the communication devices 102 of the plurality of golf carts M1, M2,... Mn with a time difference, for example, at a predetermined timing. The position information of the same golf cart M cannot always be obtained. If the actual position information is not obtained (No in Step 302), it is determined whether the actual time has passed the predicted play time calculated in Step 306 (Step 307).
In step 307, when the actual play time has not passed (No in step 307), it is assumed that the currently displayed display position information is maintained, and therefore the current display position is maintained (step 308). .

  In step 307, if the actual time has reached or passed the predicted play time (Yes in step 307), the hole position at the predicted play time that is the actual time is set as the position where the golf cart M is predicted to be positioned (step 309). The predicted position is displayed (step 310).

  Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.

  For example, if the actual position information cannot be obtained in Step 302 (No in Step 302), and if the predicted play time has not passed the actual time in Step 307, the current position information in Step 308 is obtained each time. There is no need to perform maintenance processing. When the actual position information cannot be obtained in Step 302 (No in Step 302), a timer that repeats the process in Step 302 may be provided until a predetermined time has elapsed.

Golf courses in recent years have introduced riding golf carts for the purpose of reducing the burden on the player and facilitating the progress of play. In addition, many golf carts use only a cart road provided along each hole.
Each player travels on the cart road and moves to a target place to play.
Around the green, the cart stop position may be determined in advance in consideration of access to the next hole.
In addition, since self-play without a caddy has increased, there are an increasing number of golf carts in which a guidance facility is provided on the cart road and the player operates the stop and stop with a remote controller. Therefore, an automatic stop position is provided in advance so that the golf cart does not go too much due to forgetting to operate the remote control.

The automatic stop position is provided in the vicinity of the tee ground, and if it is in the middle of the hole, a position that often stops at the second or third shot is provided in advance. It is often in a position that considers access to
Therefore, the golf cart position management device 202 may include the stop position information table 201i, and the predicted position calculation unit 201g reads the stop position information from the stop position information table 201i, and determines the golf cart automatic stop position as the corresponding course. Predicted position information may be output as the position.

  When an emergency occurs, the player is in the vicinity of the golf cart, so the golf cart position may be aimed at.

If a sudden illness comes out to a player and an ambulance has to go by contacting "Sudden illness in the 6th hole", the information on the 6th hole alone is the tee ground, the middle of the hole, green It is unclear whether there is a difference in distance of about 500 yards between the tee ground and the green for a par 5 long hole, and in case of urgent need, the hole information alone is insufficient.
It is sufficient if there is a way for an ambulance to run on the course, but if there is a valley on the way and the ambulance cannot go from the tee ground to the green unless it is detoured, it will be involved in the life or death of the suddenly ill. It might be.
The golf course management manager not only keeps track of the progress of each cart and manages it to ensure smooth play with no delay, but also to ensure that the appropriate golf cart can be rushed in the event of an emergency as described above. It is important from the viewpoint of safe operation and management to obtain information such as where the hall is located.

In the above-described embodiments, the present invention has been described as a hardware configuration, but the present invention is not limited to this. In the present invention, for example, the processing executed by the management device 5 can be realized by causing a CPU to execute a computer program.
The program can be stored using various types of non-transitory computer readable media and supplied to a computer. Non-transitory computer readable media include various types of tangible storage media. Examples of non-transitory computer readable media are magnetic recording media (eg flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (eg magneto-optical disks), CD-ROM, CD-R, CD-R / W. Semiconductor memory (for example, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM).

  The program may also be supplied to the computer by various types of transitory computer readable media. Examples of transitory computer readable media include electrical signals, optical signals, and electromagnetic waves.
