Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cart interval control system for ensuring safety between competitor parties organized for each cart in a golf course using carts.

[0002]

2. Description of the Related Art A golf game is originally a game that requires strong self-regulation by the players, but it is necessary to adjust the progress of the competition between the preceding party and the succeeding party and the flow of the course. There are many things that the administrator must consider.

In general, a front desk, a caddy master, a caddy, a starter, etc. as managers are resident at a golf course, and a competitor is started in accordance with instructions from these managers. The caddy will carry the competitor's equipment, and once the competition has begun, make sure that the preceding party has gone out of range and then let the succeeding party start the competition, and advice on how to capture the hole. It is also one of the important tasks of a caddy to monitor the flow of holes and encourage progress in case of stagnation.

However, due to a chronic shortage of manpower these days, golf carts that do not have a caddy and are equipped with equipment to be carried by the competitors themselves or carts that run on their own tracks are used. There is a place.

For a self-propelled cart, a rail traveling system is used in which the vehicle runs on rails laid along the course (Shoko 55-
(Refer to No. 30530) or laying an induction loop line on the cart road formed along the course, detecting the magnetic field strength due to the induction signal current applied to the induction loop line on the cart, extracting the left and right steering signals and guiding A guide loop method for guiding a cart along a loop line is known. Also,
Depending on the power supply system for driving the cart, there are a power supply line system and a battery power supply system. The former is a power supply line system and the latter is a battery system.

[0006]

[Problems to be Solved by the Invention] When a competition is carried out without a caddy, the progress of the competition is substantially entrusted to the voluntary management of the competitors. There is a problem that it cannot be performed sufficiently.

However, according to the golf course using the cart, the cart is a vehicle that travels on a predetermined traveling path. Therefore, if the location information of each cart is centrally managed, the location information of each cart is processed. It is possible to obtain competition management information on the course.

In order to solve this problem, one or more closed sections are assigned to each hole of the entire course, and a golf machine instructing a party in competition on each hole to "progress admission" or "standby" from the central unit. A field cart management system was proposed.

In this system, for example, one closed section for a short hole and two or more closed sections for a middle hole and a long hole are preset, and a stop position of a cart is set near one end of the closed section so as to include one of the closed sections. In this system, one closed section is dedicated to one cart and the competition is promoted.

According to this method, it is possible to give the commands of "progress control" and "stop control" to each cart while monitoring and managing the cart information reaching the stop position in each closed section by the central unit. .. Therefore, this method is convenient for the safety management of athletes, but because the closed section is fixed,
There may be cases where the progress of the competition is significantly hindered. For example,
As long as the cart of the preceding party occupies one control section, the cart of the succeeding party is prohibited from entering the control section to which the preceding cart belongs. Reached, and the distance between the leading cart and the trailing cart is kept at a safe distance that does not interfere with the competition of the trailing party, but as long as the leading cart occupies the control section, the trailing party is in front of it. The problem is that you have to wait.

It is an object of the present invention to provide a golf course distance control system for a golf course which enables management of the golf cart without providing a fixed closed section in the hole.

[0012]

In order to achieve the above object, in a golf course cart management interval control system according to the present invention, two or more front and rear wheels belonging to a control section set for each hole of the golf course are provided. A golf course cart interval control method that keeps the cart intervals always safe.The control section is a section that defines the control range of the cart with the start point near the tee ground of the hole and the end point near the green. , A self-propelled trolley that runs on a predetermined cart road, outputs position information including the movement distance moved in the control section from the start point as a base point, and the safety interval is
The distance between the leading cart and the trailing cart is predetermined as the distance necessary to ensure the safety of the athlete. The position information of the leading cart and the trailing cart is calculated, and the distance between the two carts is calculated for each hole. A stop control command is output to the succeeding cart when the safety interval is equal to or less than the predetermined safety interval, and a progress control command is output to the subsequent cart when the safety interval is equal to or more than the predetermined safety interval.

Further, the safety interval is the distance of the ball hit by the athlete,
It can be changed based on conditions such as the weather and the topography of the hall.

Further, the central unit guides the traveling of the carts, communicates with each cart, arithmetically processes each position information as an input of the position information of each cart, and operates two or more carts belonging to the control section of each hole. Of these, a stop control command and a progress control command are output to a cart that is relatively following.

[0015]

In the present invention, each hole has no fixed closed section, and the distance between the carts of the preceding party and the carts of the succeeding party on the same hole to which two or more carts belong is different for each hole. As long as the safety distance is maintained at a predetermined safety interval or longer, the following cart can proceed, and the competitors of the succeeding party can hit the ball in front of their own cart.

In the control section of the short hole where the entry of two or more carts is not permitted, the succeeding carts are made to stand by at the starting point of the control section. The "safety interval" is not fixed and can be changed taking into consideration the skill of the athlete, especially the maximum flight distance, course conditions, etc. In addition, the position information of all carts on each hole is stored in the central unit. Collecting enables centralized management.

A self-propelled cart is used as the cart 20 and enters the control section LC of the next hole from the control section LC of the hole via the interval BI between the holes.

In FIG. 2, an induction loop line (hereinafter referred to as a loop line) 6 is embedded in the cart road 5 for guiding the traveling of the cart, and the magnetic field strength due to the induction signal current flowing through the loop line 6 is detected on the cart side. , A method of controlling the steering of the cart is used. The loop line 6 is connected to the central unit 10, and the induced signal current is output from the central unit 10. The cart guiding system itself is a conventionally known one.

In the present invention, communication is performed between the central unit 10 and the cart 20 through the loop line 6, and the starting point point 4 is communicated.
When the cart enters the control section LC defined between the point a and the end point 4b, the cart 20 displays the cart position information including the accumulated travel distance information from the start point and the cart display including the cart number information. Transmitting information to the central unit 10,
These pieces of information are processed and managed by the central unit 10, and each cart is instructed for progress control or stop control, other commands,
It transmits information.

In the system block diagram of FIG. 2, the central unit 10 is basically composed of a guide signal transmitting section 11 and an information transmitting / receiving section 12. The guidance signal transmission unit 11 transmits a guidance signal current to the loop line 6, and the cart 20 detects the guidance signal current and steer-controls the traveling direction.

The information transmitting / receiving unit 12 is connected to the loop line 6 via the combiner 13, transmits various information to the loop line 6 and communicates with the cart 20. The central processing unit 1
4 is connected.

The central processing unit 14 is provided with a display unit 15, and as shown in FIG. 3, creates polling information, safety interval control processing and control information, and stores all carts 2 on the course 1.

And cart control information to the information transmitting / receiving unit 12, a cart number received by the information transmitting / receiving unit 12 in response to a call from the information transmitting / receiving unit 12, and its position. It has a function of processing information and cart control response information. The response contents from each cart are displayed on the display unit 15.

As shown in FIG. 4, the main content of the cart control information is a command for "progress control" or "stop control" of the cart in each control section. In FIG. 4, the cart distance DD between the preceding cart position DF and the succeeding cart position DA within the same control section is calculated, and the cart interval D is calculated.
Comparing D with a predetermined safety interval DS CP
Then, when DD <DS, the subsequent cart is instructed to control the progress, and when DD> = DS, the stop control is instructed. The cart can start when it receives a command for progress control, and absolutely cannot start when it receives a stop control command.

In FIG. 2, the cart 20 is basically
Information transmitter / receiver 22, distance accumulator 24, drive controller 2
6 is a self-propelled carriage that is controlled by the information processing unit 21, has a storage battery 28, and uses the storage battery 28 as a driving source for traveling. The drive control unit 26 detects the induced current of the loop line 6 and outputs a steering signal to the drive device 27 while comparing the left and right magnetic field strengths in the traveling direction. The drive device 27 is a steering mechanism including wheel drive,
Using the steering signal as an input, the cart 20 is guided to travel along the loop line 6 while steering the wheels so that the left and right magnetic field strengths are balanced. However, as long as the cart 20 is allowed to proceed, the cart 20 can be operated to start and stop freely by artificially handling the drive device 27.

The point detector 23 causes the cart 20 to detect the position of the point child 4a or 4b when the cart approaches the starting point child 4a and the ending point child 4b of the control section LC. When the signal is input to the information processing unit 21, the information processing unit 21 outputs a temporary stop braking command to the drive control unit 26. Further, the start point detection signal is a cart entry detection signal to a specific control section LC, and the end point detection signal is an advance detection signal from the control section LC. It is a signal to be specified. The cart position information that specifies the hole is input to the information processing unit 21.

The point detection unit 23 is not particularly limited to the detection method as long as it can electromagnetically, optically or mechanically detect the point element 4a or 4b and output a specific detection signal. Absent. Therefore, the point child 4a,
A structure adapted to the detection method of the spot detection unit 23 is used for 4b.

The distance integration unit 24 controls the control section LC of the hall.
When entering the inside, that is, after the point detecting unit 23 detects the starting point 4a of the control section LC, the moving distance of the cart 20 traveling in the control section LC obtained from the distance generator 25 is integrated. At the same time, the integrated distance is output to the information processing unit 21.

The information transmitter / receiver 22 communicates between the cart 20 and the central unit 10 through the loop wire 6 by means of the coil 22a, and the moving distance of the cart output from the information processor 21 in response to the call from the central unit 10. The cart control response information is output in response to the position information including the accumulated information and the cart control information from the central unit.

The command and other information transmitted from the central unit 10 are input to the information processing section 21, and the command for "progress control" or "stop control" of the cart 20 is issued to the drive control section 2.
6 to control the driving device 27 to start or stop and display the information on the display unit 29.

Unless the preceding cart and the succeeding cart enter the same control section and DD <DS shown in FIG. 4 is satisfied, the succeeding cart cannot start.

In FIG. 1 and FIG. 4, the distance DD between the leading party's cart and the cart of the succeeding party waiting at the start point of the control section LC is determined in advance after the leading party enters the first hole a. The competition of the succeeding party will be permitted when the safety interval DS is exceeded. During the competition, the competition is proceeded while always keeping the safety distance DS between the cart distance DD of the preceding party and the succeeding party.

The cart 20 of the preceding party is in the control section LC
When the point PE 4b of the end point PE is detected after reaching the end point PE, the cart is temporarily stopped, but the interval BI
Unless there are special circumstances, the section of (2) is kept running and is advanced to the second hole b. The cart that has proceeded to the 2nd hole b becomes a succeeding cart to the cart of the preceding party in the 2nd hole, and waits according to the instruction from the central device or the cart 20 to the 2nd hole b according to the above procedure.
To start. The procedure is exactly the same for all holes.

FIG. 5 shows a cart diagram for a predetermined safety interval. In FIG. 5, the carts (1) to
It is shown as (8). The safety interval can be arbitrarily set in consideration of various conditions. FIG. 6 is an example in which the safety distance DS is corrected under the conditions of the maximum flight distance KD of the athlete, the weather correction distance WE, and the terrain correction distance GR.

When the maximum flight distance KD of the players in the party is large, it is necessary to secure a large safety interval with respect to the preceding party, and it is impossible to secure an unnecessarily safe interval for a party whose flight distance is not so long. It's useless. Flight distance also depends on weather and terrain.

In order to cope with such a change in conditions, it would be advantageous if the safety interval DS could be corrected on the side of the central unit 10 or the cart 20. In FIG. 2, the central unit 1
A flight distance registration unit 16 that corrects the safety interval under these conditions is added to the central processing unit 14 of 0.

FIG. 7 shows an example in which the players of each party set the maximum flight distance and correct the safety interval. According to this combination example, the cart diagram is as shown in FIG. In FIG. 8, the carts are (1)-
It is shown by (12).

As is apparent from the comparison of FIG. 8 with FIG. 5, the number of parties that can compete in the diagram of FIG. 5 in the same time zone is eight, whereas in FIG. Party competitions are possible. In this way, by appropriately correcting the safety interval, it may be possible to smoothly progress the competition.

In the above embodiment, the cart 20 is started or put on standby after waiting for a command from the central unit 10. In the central unit 10, each control section is displayed on the display unit 15 based on each cart information. If the above cart display information is displayed, the progress status of the competition can be grasped at a glance, and various managements can be facilitated based on the status.

For example, by calculating the exclusive time of the cart on a specific control section and comparing the exclusive time with a predetermined standard time, it is possible to know the delay or advance situation of the competition, and when necessary, delay Can alert the party.

The information content between the central unit 10 and the cart 20 can be freely set. For example, service information such as the terrain of the course and the method of conquering the course can be provided to the party in the competition visually or audibly to the athlete of the cart.

Further, from the cart side, the scores for each hole of each athlete can be transmitted to the central unit for totaling, and the number of course rounds can be grasped by the central unit. Information transmission is not limited to between the central unit and the cart. It is possible to provide advance notice of the start time and cart operation status as service information to the subsequent parties on standby.

In the above embodiments, the central control system in which the respective carts on the course are managed by the central device has been described. By communicating and issuing commands for "stop control" and "progress control" from the preceding cart to the succeeding cart, the objective can be achieved sufficiently.
Further, the cart and the central unit or the communication between the carts can be performed by a dedicated communication cable or wireless communication instead of the induction loop line.

[0043]

As described above, according to the present invention, the distance between the cart of the preceding party and the cart of the succeeding party can be monitored on each hole, and the competition can be advanced while keeping the distance between both carts at least the safety interval. The interval can be set and changed freely, and the safety interval of the competition can be replaced with the cart interval to ensure all weather, all terrain, and the quality of the competitors, so safe self-play is possible. This has the effect of improving the efficiency of competition traffic in golf cart cart units and shortening the competition time, thereby enabling efficient golf course management.
