[0001]

[Industrial applications]

 The present invention relates to a golf data management / provision system for providing various information during golf play and managing golf data after play.

[0002]

[Prior art]

 Needless to say, the number of golf courses is increasing steadily in recent years as the golf population is rapidly increasing due to the expansion of leisure and leisure-oriented activities.

Generally, a clubhouse is attached to a golf course, and at the clubhouse, a player first receives a score sheet, a local rule, a course route, a sheet in which notes, etc. are described. He carries a golf bag called an exclusive caddy and goes around the course with an assistant who advises him in playing.

There are generally 18 out / in holes, 18 holes in total, and a standard number of hits (par 3 to 5) is set for each hole, with a total of about 72 hits as a reference.

Bunkers, ponds, etc. are generally arranged in appropriate places on the fairway from the tee to the green to form a course with rich undulations.

A group of 3 to 4 players goes around the course while writing the number of strokes on the score card for each hole.

[0007] The player takes a course, selects a club, and boldly attacks while estimating the distance. However, in the case of the first course or a beginner, it often happens that the caddy's advice is used when playing.

For golf, it is common to assess the handicap in order to equalize the difference in skill of the players and make the game interesting (this is usually done at each club in Japan), but this assessment method is used. In private competitions, the Pelia method or the Double Pelia method (new Pelia method) is often used.

[0009]

[Problems to be solved by the device]

 However, it is inevitable that the management of golf courses will be rationalized due to the recession.

[0010] For example, it is necessary to rationalize such that the fee is suppressed and the maintenance and maintenance costs of the course are reduced by traveling around the course only by the player using the riding cart without the assistant's caddy. ing.

At the same time, efforts will be made to enhance the services to players, and to make a golf course attractive by distinguishing it from other golf courses.

As mentioned above, in the case of no caddy, the player has to make all the situation judgments while playing, but it is difficult for the beginners or the first time to play on the course to judge the appropriate situation. Always.

For example, it is not easy for an amateur to accurately determine the distance to the green, the position of the bunker, and the optimal course taking.

In addition, the current situation is that the player does not pay attention to necessary information such as OB lines, local rules, and club-specific etiquette.

In general, caddies are mainly housewives and students, part-timers, and it is difficult to train caddies, and it is difficult to expect uniform skills.

Therefore, the above-mentioned information can be easily obtained during the play, and the information is replaced in place of the information provided by the conventional caddy (generally, it is not accurate enough to have full trust). A device that provides the

On the other hand, players usually look forward to improving their skills, but in general, personally save a score table and usually start by grasping how much the average is. is there.

[0018] Therefore, it is considered that the enjoyment after golf play will be further enhanced if the fluctuation of the performance throughout the year, the calculation of the handicap, and other numerical information can be easily calculated and stored. There is no device that manages and provides data.

The present invention has been made in view of the above golf situation, and provides a golf data management / provision system that manages information such as caddies and data such as individual performance.

[0020]

By providing a golf data management / provision system characterized by having a portable mobile device having a port It achieves the above object.

[0021]

[Action]

 The golf data management / providing system according to the present invention has a function of measuring the distance to the vicinity of a pin in a portable mobile device carried by a golfer during golf play.

That is, first, the oscillator of the portable mobile device emits the radio wave f1 having a frequency of about 150 MHz, and the counter starts counting at the same speed as f1.

Next, when the receiver of the fixed device embedded in the green or installed near the green receives the radio wave f1, the oscillator immediately oscillates a radio wave f2 having a frequency of about 150 MHz and a frequency different from f1.

Upon receipt of the radio wave f2, the portable mobile device immediately stops counting, converts the total number of counts into a distance by the distance conversion circuit, and displays the distance on the display circuit.

That is, since the counter is a high-speed counter and counts at the same frequency as f1 or f2, the fixed device receives the f1 transmission start time t1 from the portable mobile device and transmits the f2. Then, the time difference ΔT from the time point t2 when the portable mobile device receives the f2 is calculated from the total count number N.

Next, the net radio wave propagation time ΔTo obtained by subtracting the internal delay time (the reaction required time of the circuit) of the portable mobile device and the fixed device from the time difference ΔT is divided by 2 to a radio wave transmission speed of 300,000 km. The distance is calculated by multiplying / second.

In addition to the distance measurement display function of the portable mobile device of claim 2, the input / output port exchanges data with an external parent computer, and various data received by operating buttons are selected and displayed on a liquid crystal display. Having a function, the central processing unit performs arithmetic processing for controlling the above various data. That is, various data received from the parent computer according to claim 2 is displayed on the liquid crystal screen by selecting a predetermined operation button. Therefore, the player can appropriately check the necessary data on the LCD screen during the play.

In addition to the above functions, the portable mobile device of claim 3 stores and saves the golf performance data in the memory device, and the calculation circuit uses the built-in calculation IC chip to extract the data of the memory device. The individual annual average and handicap by the Pelia method are calculated, and the calculation result is displayed on the liquid crystal display circuit. Therefore, golf lovers can easily calculate, record, and organize their own golf results.

【Example】

 An embodiment of a golf data management / providing system according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing a distance measuring system in a golf data management / provision system according to the present invention.

In the mobile device 1 of FIG. 1, when the operation button SW1 is closed, the waveform shaping circuit 3 outputs a distance measurement start signal S1.

The start signal S1 is input to the monostable circuit 5 to output the operation control signal S2 of the oscillator 7.

The oscillator 7 oscillates a VHF band radio wave having a frequency of about 150 MHz, and is composed of a self-excited oscillator or a crystal oscillator.

The oscillator 7 receives the S2 signal and starts oscillating at the first oscillation frequency f1. At the same time, the S2 signal activates the counter 17.

The counter 17 is a binary counter composed of a flip-flop circuit or an n-ary counter which is a modification thereof, and operates at a count speed of 150 M times / sec which is equivalent to the first oscillation frequency f1. It is a high-speed counter that starts at the rising edge of the S2 signal and stops at the falling edge.

The first oscillation frequency f1 of the oscillator 7 is amplified by the amplifier 9 and transmitted from the antenna 10 as a VHF radio wave.

Since it is necessary and sufficient for this radio field intensity to be receivable within the golf course, it is generally weak if it is receivable at a distance of several hundred meters in order to prevent radio wave interference of other equipment. Desirable from a point of view.

Next, the fixing device 50 fixed to the green or a position near the green senses the radio wave of the first oscillation frequency f 1 from the portable moving device 1 through the antenna 23 in the tuning circuit 25.

After tuning, the output of the tuning circuit 25 is amplified by the amplifier 27, and the waveform shaping circuit 29 outputs the operation control signal S4 for starting the oscillation of the oscillator 31. This operation control signal S4 keeps the oscillator 31 oscillating at the second oscillation frequency f2 for a predetermined time (about 1 to 100 msec).

The radio wave of the second oscillation frequency f2 amplified by the amplifier 33 is transmitted as a weak radio wave in the VHF band near 150 MHz through the antenna 23 as in the case of the first oscillation frequency f1 described above. This oscillation frequency is slightly different from f1.

Therefore, the tuning circuit 25 of the fixing device 50 is required to have a high Q so that the tuning circuit 25 tunes to the first oscillation frequency f1 but does not tune to the second oscillation frequency f2. The same applies to the tuning circuit 15 of the portable mobile device 1 described below.

Next, the radio wave of the second oscillation frequency f2 received on the side of the mobile device 1 is detected by the modulation circuit 15, and its output is sent to the waveform shaping circuit 11 via the amplification circuit 13 to the reset signal. S3 is generated.

This reset signal S3 is input to the above-mentioned one stabilizing circuit 5 to stop the output of the operation control signal S2.

When the operation control signal S2 is stopped, the counter 17 stops counting.

The total count number N of the counter 17 is converted by the distance conversion circuit 19 into a distance of yard or meter by a predetermined program.

That is, FIG. 2 is a diagram showing a time chart of SW1, S1 to S4, f1 and f2 and the count C of the counter 17 in the portable mobile device 1 and the fixed device 50 (the fixed device side is inside the broken line frame). However, in the figure, a count start time t1 at which the first mobile device oscillates at the first oscillation frequency f1 and the count of the counter starts, and after the fixed device receives f1, f2 is transmitted and the mobile device moves. The device calculates the time difference ΔT from the count stop time t2 when the device receives the f2 and stops counting, from the total number N of counts.

Next, a net radio wave propagation time ΔTo (= ΔT− (Δtr1 + Δtr2) obtained by subtracting the internal delay times Δtr1 and Δtr2 (reaction required time of each circuit) of the mobile device 1 and the fixed device 50 from the time difference ΔT. )) Divided by 2 is multiplied by the radio wave propagation speed of 300,000 km / sec to calculate the distance.

In principle, the higher the speed of the high-speed counter, the higher the accuracy becomes, but at 150 M times / sec, the accuracy is approximately ± 1 m. To determine the distance during golf play, a count speed equal to the frequency is used. Considered sufficient.

The number of distances calculated by the distance conversion circuit 19 is displayed on the liquid crystal display panel as a yard or a meter value on the display circuit 21 (see FIG. 4 described later).

Next, FIG. 3 shows the course route, the course shape, the normal course, the distance, the number of pars, the green shape, the bunker position, the OB line, and the local, which are specific to the golf club, from the parent computer 60 installed in the clubhouse. It is a conceptual diagram for explaining a means for storing at least one data of the position of the pin of each hole, which is the data of the rule, notes, data and the day and the grass condition, in the portable mobile device 1 through the input / output port 64. is there.

In the figure, a memory card 61 is a card in which an EPROM of a non-volatile memory or an IC chip 62 of a flash memory is incorporated, and a connection terminal 63 is arranged at one end. By using this memory card 61, a large number of golf courses can be prepared (stored) on the golf course side in advance, so that data can be passed to a large number of golfers without delay. Further, since it is robust and compact, it is easy to handle, and it can be said that it is an optimal memory device to be loaded into the portable mobile device 1 according to the present invention.

It is also possible to incorporate a writable / erasable IC memory in the portable mobile device 1 and directly read data from the parent computer 60 by the data transfer cable 65. In this respect, the storage means has a drawback that it is difficult to transfer data to a large number of portable mobile devices 1.

On the other hand, a general-purpose 3.5-inch floppy disk 66 may be used as the storage device in the same manner as the memory card. However, while the floppy disk 66 is inexpensive, it is difficult to downsize the disk drive system device.

FIG. 4 is a front view showing the outer shape of the portable moving device 1 according to the present invention. The liquid crystal display panel 71 in the drawing has the number of holes, the number of pars (4), the number of hole distances for yard display, The course shape, pond, bunker, green, remaining distance (152 yards), OB line, etc. are displayed at a glance.

Other data for the liquid crystal display panel 71 include course roots as shown in FIG. 5A, course shapes, normal course removal, green shapes for each hole as shown in FIG. 5B, and pin positions. , Turf and bunker position are shown. Needless to say, data for local rules and precautions are also displayed in characters.

The various data described above are appropriately selected and displayed by the operation button group 73 arranged in the mobile device 1. The above mechanism can be easily realized by using a general-purpose desktop computer or so-called electronic notebook technology.

Further, instead of writing the score being played on a conventional score card, it is possible to key-in with the operation button group 73 and further output the score data of the day to the parent computer 60 through the input / output port 64. Of course,

For example, FIG. 5C shows a state in which scores for up to 4 holes are displayed for four people.

Next, it has a memory device for storing and saving the data of the golf result after playing, a calculation circuit for calculating the average and handicap from the data, and an output port for outputting the calculation result to an external device. With a portable mobile device equipped with a portable mobile device, by using the technology of a desktop computer with a built-in general-purpose calculation IC chip, it is possible to easily calculate year-to-year changes in grades, handicap, and other numerical information. Can be calculated and saved.

For example, FIG. 5D shows a state in which the results of all scores in 1992 are displayed for each golf course, and the annual average is calculated and displayed.

There are various ways to calculate the handicap, but in a private competition in Japan, a more accurate and arbitrary calculation method is 6 holes out, 6 holes in, and a total of 48 pars. Choose a 12-hole that can be used, and subtract the course par from the number obtained by multiplying the total score in these 12-holes by 1.5, and use the new pelia method with 80% of the remaining number as the handicap (double-pelia method). Is common.

The above handicap calculation can be calculated from the course data received from the parent computer of the golf course and the personal results input on the day by a program of a predetermined calculation formula.

The above-mentioned fixing device 50 is installed in the green of each hole or in the vicinity of the green, but it is necessary to take measures so as not to become an obstacle to play by burying it in the green.

Further, since the holes are adjacent to each other, it is necessary to prevent the portable mobile device from interfering with the fixed device in each hole.

In this respect, the second oscillating frequency f2 in the fixing device of each hole is made different, and the tuning circuit 15 of the portable mobile device 1 is made variable, so that only the fixing device f2 of the specific hole is selected. There is a way to receive.

Further, a unique identification signal (binary pulse signal) is given to each hall in advance, and the identification signal is transmitted before the portable mobile device 1 transmits the first oscillation frequency f1. A method is conceivable in which only the fixing device of the specific hole is provided with a selection response circuit that becomes a standby state in response to the identification signal.

Further, since the fixing device must be in a state in which the power is always on during the play, it is assumed that the solar battery is used as a power source in consideration of energy saving and maintenance.
