Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a golf course where players freely drive and move around in self-propelled golf carts, which are equipped with caddies, golf bag transportation rails, etc. The present invention relates to a golf cart operation management method and a management system therefor that are extremely useful when applied to.

[Prior Art] As is well known, one method of playing golf at a golf course is to form a party of players of 4 Å or less, and to start the parties at 6 minute intervals.

If the players' skills are approximately the same, play will proceed smoothly with intervals between parties commensurate with the six-minute interval mentioned above.
There will be no large number of parties congregating in one hall.

However, in reality, play is rarely performed under the ideal conditions described above, and there are cases where a large number of parties gather at a hole called the so-called instrument hall, leaving other holes empty. In many cases, this is a major cause of poor playing efficiency.

In addition to this, there are cases where one party's players have bad manners, or there are several beginners in the party, and one party is followed by many other parties.

In cases like the above, if a golf course has a caddy, the caddy will take charge to ensure that play is as smooth as possible. Golf courses are automatically controlled to avoid concentrating on one spot.

However, there are few golf courses where there are no caddies, no bag carrying rails are installed, and players load their own bags onto carts and drive around the golf course themselves while playing. do not have.

[Problem to be solved by the invention] In the golf course using the cart driving method described above, one cart is
If a large amount of dirt accumulates in one spot, it is best to wait patiently and at best there will be no more than an argument; however, accidents may occur due to the player's poor driving skills, or someone may become ill while playing. However, there are surprisingly many cases where the cart's battery runs out of power and the cart stops moving.

Even if such an accident or power outage occurs, conventionally there was no way to properly report it to a management department such as the master office, which could cause trouble for others or force people to go on foot to contact them themselves. did not become.

In view of the above-mentioned circumstances, it is an object of the present invention to not only be able to accurately grasp the operation status of carts in the entire area of the golf course at a golf course using the cart operation method, but also to be able to accurately grasp the operation status of carts throughout the golf course. Give appropriate commands, or in the event of an accident, instantly determine what type of accident has occurred in which hole and at what location, communicate with each other, or immediately go to rescue. The present invention aims to provide a novel golf cart operation management method and a management system therefor.

[Means for Solving the Problems] The present invention firstly provides a golf cart with a receiving antenna capable of receiving radio waves from an artificial satellite, and centrally receives the received waves received by each golf cart at a centralized management department. Then, the central management department calculates the two-dimensional position of the cart by processing the received waves sent from the cart running on the golf course, displays it on the golf course layout image, and calculates the two-dimensional position of the cart. Second, as a system that makes this possible, radio waves are sent and received between an antenna that can receive radio waves from artificial satellites and the central management department at the golf course. a plurality of carts to which antennas and transmitting/receiving devices are attached, and said centralized control department capable of transmitting and receiving radio waves between said carts; and said artificial satellite installed within said central control department receiving radio waves. a processor that processes the received radio waves and determines the two-dimensional position of the cart on the ground from the satellite radio waves received by the cart; This configuration includes an image processing device capable of displaying images on a layout image.

[Function] Many satellites that transmit time signals have already been launched, and a system has been established in which signals can be received from any one of the satellites 24 hours a day, so a receiving antenna is attached to each cart and the central control department If the received results are processed in the system, the two-dimensional position of the cart on the ground in the golf hole layout can be accurately grasped, and microwave communication etc. can be performed between the cart and the central management department. If this is done, it will be possible to properly issue operational instructions, etc., and it will also be possible to take prompt response measures in the unlikely event of an accident.

[Example] The present invention will be described below with reference to Examples.

FIG. 1 is an explanatory diagram showing how the operation of golf carts 20, 20 according to the present invention is managed using the management system according to the present invention.

1.1 is an artificial satellite, and each of these artificial satellites 1゜1 is equipped with an atomic clock, and about 1.1
．． Extremely accurate time signal radio waves 2,2 are transmitted using frequencies of 2Gllz and approximately 1.5GHz, and the system is open to the private sector and can be freely received anywhere on Earth.

FIG. 4 is an explanatory diagram showing a case where a time signal radio wave 2 transmitted from such an artificial satellite 1 is received and the positions of points P and Q are measured. Antennas 3s and 32 are installed at points P and Q, respectively, and the phase angles of radio waves are measured with respect to the clocks at points P and Q, respectively. Radio wave 2 has 4th
As shown in the figure, there are same phase planes at equidistant radii from the satellite, and the same phase planes passing through point P and the same phase planes passing through point Q are different as shown in the figure. A delay time Δt occurs in the arrival of the radio wave 2 at the P point with respect to the Q point, and this becomes a phase difference between the received radio waves.

The signals received at each of the points P-Q are converted into electrical signals by the receiver 5 52, and the stored phase data is calculated by the processor 8, thereby obtaining the phase difference and the longitude of the artificial satellite 1.1 at that time. and latitude, point P or Q on the ground
The position of a point can be determined accurately. Therefore, even if a golf cart 20 having a radio wave receiving antenna 3 of a global positioning system (hereinafter referred to as GPS) is running at an arbitrary position such as the point P to Q in the golf course as shown in FIG. , you can instantly know its location.

The GPS image processing device 7 shown in FIG. 1 stores this course layout in its entirety, and is configured so that it can display the entire layout image or partially zoom in on the CRT.

Cart 2 starts sequentially from IN or OUT
The antennas 3, 21 and transmitter/receiver 22 described earlier in FIG. , receives the GPS signal from the artificial satellite 1.1 and continues to send the received signal to the in-field antenna 31.

The GPS signals received by all of the carts 20.20 that have started are received by the GPS receiver 5, processed, and their current positions flash on the CRT of the GPS image processing device 7, which displays the course layout. displayed as a signal.

FIG. 3 shows how the GPS signal from such a cart 20.
7A is an explanatory diagram showing a state in which cart position signals 7a, 7a are displayed blinking. FIG.

Figure 3 shows 2, 3 and 7 of the layouts in Figure 5.
This is a zoomed-in view of the No. 1 hall, but if there is a particular part of the layout that you would like to draw attention to, it is also possible to zoom in like this. If the configuration is such that communication equipment can be used to communicate with the above-mentioned equipment of the other party's cart 20, it will be possible to take emergency measures in the event of a person becoming stranded due to the on-board battery running out of electricity or in the event of a sudden illness. You can respond directly to the situation,
It is possible to perform safe and smooth on-site management.

In addition, since it is possible to constantly monitor where carts are stuck during play, it is possible to issue appropriate commands to promote play, contributing to smoother progress of play as a whole. is big.

[Effects of the invention] As mentioned above, in the past, it was impossible to know the operating status of the entire cart at a cart-based golf course.
According to the present invention, regardless of weather conditions such as fair weather or fog,
The position of all the carts at the start of the entire golf course can be properly known in real time, which greatly contributes to smoother play, and in the event of an accident, we can quickly go to the spot and take countermeasures. Its usefulness is extremely great, such as being able to take
