The meeting rate history information obtained by the speed measuring instrument is transmitted to a PC. The PC displays the head of the golf club as a background, performs plotting toward the center of the graphic of the head when the meeting rate is higher, and performs plotting toward the peripheral part of the graphic of the head as the meeting rate becomes lower. Consequently, the user intuitively recognizes the result of the meeting rate. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a golf support system and a program that can appropriately provide information on the meet rate obtained by measuring the head speed and ball speed of a golf club.

  A device using a Doppler sensor is known as a velocity measuring device that measures the maximum velocity of a moving object to be measured. In a conventional speed measuring device using this Doppler sensor, the object to be measured is intended for a device that moves at a constant speed (such as a vehicle) or decelerates (such as a thrown ball). Therefore, if the speed data measured first after the start of measurement is displayed as the maximum speed, no practical problem has occurred. On the other hand, when the object to be measured that accelerates suddenly from the state of zero speed and reaches the highest speed at the point of hitting the ball, such as a swing motion of a golf club or the like, is detected by the Doppler sensor. The moment when the measurement object enters the range is not necessarily the maximum speed of the swing, and the conventional method of displaying the first measured speed after the start of measurement cannot capture the maximum speed of the swing was there.

  In order to solve such a problem, there are conventional inventions disclosed in Patent Documents 1 and 2. In the small radar for measuring the club head speed and tempo disclosed in Patent Document 1, the RF Doppler radar is used to continuously measure the speed, and the maximum speed is measured by an arbitrary measurement speed higher than the previously stored speed. The maximum value of the speed is obtained by replacing the stored value.

Further, the golf club motion measuring device described in Patent Document 2 obtains the maximum value of the speed by analyzing the signal of the frequency shifted by the Doppler effect captured by the ultrasonic sensor by wavelet transform.
JP 2006-326318 A Japanese Patent Laid-Open No. 2003-210638

  In the inventions disclosed in Patent Documents 1 and 2, only the head speed and the like are required, and sufficient information cannot be provided for the golfer. That is, if it hits the ball in the same way, the higher the head speed, the longer the flight distance. Needless to say, however, even if the head speed is the same, the flight distance also varies depending on how the head hits the ball, such as whether or not the ball is firmly punched. That is, in general, it can be said that the longer the ball can be punched (the higher the meet rate), the longer the flight distance.

  Therefore, in actual practice, instead of simply increasing the head speed, it is necessary to increase the meet rate or increase the head speed while maintaining the meet rate above a certain standard. . However, conventional devices cannot provide appropriate information for such practice.

  Then, an object of this invention is to provide the golf assistance system which can provide a user with the information regarding the meat | meet rate at the time of actually hitting the ball easily.

  In order to achieve the above-described object, a golf support system according to the present invention includes (1) a head speed measuring means for obtaining a head speed of a club head that moves with a swing of a golf club, and a club head that moves with the swing. A ball speed measuring means for obtaining a ball speed of the ball hit by the ball, a meet rate calculating means for obtaining a meet ratio based on the head speed and the ball speed respectively obtained by the head speed measuring means and the ball speed measuring means, and An informing means for informing a nice shot when the obtained meet rate is compared with a preset reference meet rate and the meet rate exceeds the reference meet rate. Each measuring means and the meet rate calculating means are realized by the microcontroller 14 in the embodiment. The meet rate calculating algorithm in the meet rate calculating means may be obtained by dividing the ball speed by the head speed as shown in the embodiment, or may be obtained by other methods. In addition, the golf support system of the invention of (1) is realized by the speed measuring device 10 in the embodiment.

  The reference meet rate may be set so that the user can determine and set a target meet rate. When the target meet rate (reference meet rate) is exceeded, a nice shot is notified, and the user can devise and improve the swing so that the nice shot is notified. In this way, goals can be set according to the level of each person. Therefore, training can be performed while gradually increasing the target meet rate. For example, if a notification is made after measurement, it can be immediately confirmed whether the target has been reached.

  The notification of the nice shot may be performed with light, for example. For example, an LED indicating a nice shot may be turned on, a predetermined display may be performed on a display unit such as a liquid crystal screen, or a sound indicating a nice shot may be output. When using a sound, for example, a voice “Nice shot” may be output.

  (2) A means for storing and holding the obtained meet rate and outputting history information of the stored meet rate to a display device may be provided. In the embodiment, the display device is a monitor of a personal computer, but may be a display unit of the speed measuring device 10. In this way, the reference meet rate can be determined by looking at the history of the own meet rate, which is a guideline for determining the reference meet rate. The display based on the history of the meat rate may be the history of the meat rate itself, or a value obtained by performing a predetermined calculation based on the history (for example, statistical values (average value, variance, standard deviation, median value, etc.)) You may make it do. Moreover, you may make it output as a table | surface and figure (for example, graph) based on the calculated | required value. In this way, it is possible to easily set a target that suits itself. Therefore, it is possible to perform training toward the goal more easily.

  (3) The display based on the history of the meet rate displays the head of the golf club as the background, and when the meet rate is high, plots closer to the center of the head, and as the meet rate becomes lower, Plot to the periphery. As a result, when the meet rate is high, it is plotted near the center of the head, whereas when the meet rate is low, it is plotted at the periphery of the head. You can grasp your own meet rate. By displaying in this way, the user can intuitively grasp the situation of his own meet rate at a glance. Therefore, the determination of the reference meet rate can be performed very easily intuitively. Note that plotting may be performed with, for example, dots or marks.

  (4) The plot may be performed by plotting to a position on the circumference of a circle or ellipse. By making the same meat ratio plotted on the circumference of the same diameter centered on an arbitrary position in the head diagram (preferably centered on the center of the head), High and low can be understood intuitively at a glance. Note that the position on the circumference of the plot may be set randomly or in a predetermined pattern.

  (5) It is good to provide the function which sets the meet rate corresponding to the designated point to the standard meet rate by designating the point on the head of the golf club displayed on the display. This designation may be performed by detecting a click on a button such as a mouse or a touch on a touch panel or the like. This makes it easy to set the reference meat rate. Of course, the reference meet rate may be set numerically.

  (6) The golf club head displayed on the display device may be set for a user's actual club. As for the actual club of the user, for example, it may be possible to set a photograph of the club head taken by the user, for example, a photograph or a figure stored by a club vendor on a server on the net, You may enable it to download and set via the net. As for the user's actual club, for example, an image or a picture may be prepared and set for each club type. In this case, the display of the meat rate is preferable because it gives a better feeling.

  (7) The club type of the used golf club may be stored in association with the meet rate, and the history of the meet rate may be output for each club type. In this way, the user can check the meet rate for each club type, and can easily recognize the club types that are good and bad.

  (8) The history information of the meet rate may be stored and held separately for each user, and may be provided with a switching function for displaying the history information and setting the reference meet rate for each user. Thereby, since it can switch and use by several users, the convenience improves.

  (9) A function of outputting an estimated flight distance by multiplying at least one of the measured ball speed and head speed by a flight distance coefficient may be provided. In this case, it is preferable to set the flight distance coefficient for each club type, specify the club type to be used, obtain the speed thereof, and calculate the estimated flight distance. This function is incorporated in the speed measurement device 10 in the embodiment. However, in the case of a system configuration in which the history information of the meet rate is displayed by a device different from the speed measurement device, such as a PC, as in the embodiment, it is incorporated in the PC side. But it ’s okay. However, it is preferable to incorporate it in the speed measuring device 10 because the user can also know the estimated flight distance associated with the swing. This flight distance coefficient may be set by the user by inputting it, or the club vendor (for each model number) stores, for example, the club vendor for each club type on a server on the network, and the user can When a club item is selected, it may be downloaded and set via the net.

  (10) an estimated flight distance calculation function for calculating and outputting an estimated flight distance by multiplying at least one of the measured ball speed and head speed by a flight distance coefficient; a function for displaying a target flight distance; It is determined whether the estimated flight distance obtained by the estimated flight distance calculation function is within a range set on the basis of the target flight distance, and when it is within the range, means for notifying the target achievement is provided. Good. This function corresponds to the challenge mode of the embodiment. In this way, it is possible to enjoy the practice of performing a swing corresponding to the target flight distance to be challenged. The target flight distance may be set and displayed randomly on the device side as in the embodiment, or may be specified by the user.

  (11) The means for displaying the history information of the meet rate on a display device is a device different from the speed measuring device including the head speed measuring means, the ball speed measuring means, the meet rate calculating means, and the notifying means. (In the embodiment, a personal computer) may be used. Data exchange between the two may be performed via a recording medium such as a micro SD memory card or via communication. Accordingly, the speed measuring device can be reduced in size and can be easily set.

  The program of the present invention is a program for realizing a function of displaying history information described in any of (2) to (8) on a computer (a computer described in any of (2) to (8)). Program for functioning as history information means).

  In the present invention, information on the meet rate when the ball is actually hit (display of meet rate history information, notification of a nice shot, etc.) can be provided to the user in an easy-to-understand manner.

  FIG. 1 and FIG. 2 are diagrams showing an example of a usage state of a speed measurement device 10 that measures measurement data and the like required for displaying and managing a meet rate and the like in the golf support system of the present invention to obtain various characteristics. It is. As shown in the figure, a speed measuring device 10 that measures the swing speed and ball speed of a golf club collects information (each of the above speeds) for obtaining a meet rate, or actually calculates a meet rate. It has a function. The speed measuring device 10 is installed at a predetermined position behind the golfer 1 who swings the golf club 2. The specific installation position is a position where the detection range of the golf club speed measurement device 10 includes a point where the head 2a of the golf club 2 during the swing moves at the maximum speed. As an example, as shown in FIG. 1, the vicinity of the lowest point of the movement locus K of the head 2a of the golf club 2 is the impact position with respect to the ball B, and the movement speed of the head 2a is usually the maximum speed near the position. Therefore, it is on the tangent L of the lowest point of the movement trajectory K and the rear of the golfer 1 is set as the installation position. In the present embodiment, the distance between the ball B and the golf club speed measurement device 10 does not need to be determined strictly, but the golf club 2 does not hit the golf club speed measurement device 10 during backswing. For example, the distance between the ball B and the speed measuring device 10 is about 1 m. As will be described later, since the Doppler sensor is built in the speed measuring device 10, the opening surface 11 a of the antenna of the Doppler sensor is installed so as to face the ball B (facing the tangent L). In the present embodiment, the golf club speed measuring device 10 is described as being installed at a predetermined position behind the golfer 1 swinging the golf club 2, but may be installed at a predetermined position in front of the golfer 1. The club to be used may be anything such as wood iron putter.

  FIG. 2 shows an example in which the golfer 1 is right-handed. In the case of a left-handed golfer, this can be dealt with by installing the golfer in a state where the left and right sides are reversed. That is, the golf support apparatus according to the present embodiment can handle both right-handed and left-handed.

  FIG. 3 is a plan view showing the appearance of the speed measuring device 10, and FIG. 4 is a block diagram showing its internal configuration. As shown in FIG. 3, the speed measuring device 10 is configured by housing each component shown in FIG. 4 inside a flat rectangular housing 20 that is waterproofed (waterproof structure). Some of the components are exposed to the outside of the housing 20.

  As shown in FIG. 4, the speed measuring device 10 includes a microwave Doppler sensor 11 having an output frequency of 24.15 GHz, and an output signal of the Doppler sensor 11 (one wave corresponds to 6 mm of movement of a golf club head). Amplifier 12 for amplifying the signal) and the signal amplified by the amplifier 12 are compared with a reference value, and a Doppler pulse (a high level signal when the reference value is equal to or higher than the reference value and a low level signal when the reference value is smaller) is output. A comparator 13 and a microcontroller (control unit) for inputting a pulse signal output from the comparator 13 and inputting an analog signal amplified by the amplifier 12 to a built-in A / D converter to obtain a swing speed, a ball speed, etc. 14 and display of swing speed and the like by control from the microcontroller 14 A display unit 15 that performs a switch group 16 connected to the microcontroller 14, a communication interface 18, a. Furthermore, the speed measuring device 10 includes a recording medium such as an internal memory or a removable external recording medium (such as a micro SD memory card). On this recording medium, measurement data, device setting information, virtual golf course, course data indicating the actual golf course hole layout, and the like are recorded. Data about an actual golf course includes, for example, the position of an object on the course such as a golf course green or a bunker, and a map of the golf course (including position information). These pieces of information can be the same as those disclosed in, for example, Japanese Patent Application Laid-Open No. 7-57189 and Japanese Patent Application Laid-Open No. 2003-339929. Thereby, the trajectory of play on an actual golf course can be recorded. Moreover, the game using a virtual golf course can be played by memorize | storing the hole information of a virtual golf course.

  The display unit 15 is formed from an LCD, an organic EL display, or the like. As the communication interface 18, various interfaces for connecting a personal computer can be used. For example, a wired type such as USB, and a wireless type such as Zigbee, Bluetooth, and wireless LAN are included. Via this communication interface 18, data can be transmitted to and received from a personal computer. As an example of data transmission / reception, for example, the speed measurement device 10 downloads data about a golf course from a personal computer, or uploads measurement data or other history information stored in the personal computer to the personal computer. be able to. In addition, a removable recording medium (such as a micro SD memory card) that can be read by a PC can be mounted, and the above-described data exchange can be performed via the recording medium.

  A front surface 20b of the housing 20 serves as an opening surface 11a of the antenna, and a rear surface 20c of the housing 20 is provided with a micro SD memory card slot. In addition, a battery storage unit is provided on the back surface (lower surface) side of the housing 20. Further, the display unit 15 and the switch group 16 are exposed on the upper surface of the housing 20. In the present embodiment, the switch group 16 includes four operation buttons including a power button B1, a mode select button B2, a club select button B3, and a function button B4. When each of the operation buttons B1 to B4 is pressed, the press is notified to the microcontroller 14, and the microcontroller 14 performs a predetermined process.

  The power button B1 is for controlling the power supply of the speed measuring device 10 to be turned on / off, and is a button for switching the device power supply on / off by a long press. When the microcontroller 14 recognizes that the power button B1 has been pressed for a long time when the device is turned off, the microcontroller 14 turns on the power and the power button B1 is pressed for a long time when the device is turned on. If it is recognized, control to turn off the power is performed.

  The mode select button B2 is a button for instructing mode switching. As will be described later, the speed measurement device 10 according to the present embodiment assumes a “measurement mode” for measuring and displaying various characteristics associated with a swing for each swing, and a virtual golf course as if it were a virtual golf course. It has a “training mode” that allows you to go around the course. Therefore, when the microcontroller 14 recognizes that the mode select button B2 has been “long pressed”, the microcontroller 14 alternately switches between the “measurement mode” and the “training mode”. The microcontroller 14 displays the “GAME” logo in the upper left corner of the display unit 15 when the current mode is “training mode”, and does not display the “GAME” logo when in the “measurement mode”. . Therefore, the user can recognize whether the current training mode or the measurement mode is in effect based on whether or not the “GAME” logo is displayed. In addition, actual play can be recorded by measuring and recording each shot (swing) during the play while actually playing in the measurement mode.

  Further, various characteristics that can be obtained in the measurement mode are “head speed”, “ball speed”, “estimated flight distance”, and “meet rate”. The head speed and the ball speed are obtained based on the output of the Doppler sensor. In other words, when the power is turned on, a Doppler pulse obtained by encoding the analog waveform obtained by amplifying the output of the Doppler sensor 11 with the amplifier 12 by threshold processing is input from the comparator 13 to the microcontroller 14. The microcontroller 14 obtains the Doppler pulse cycle using a built-in timer, and obtains the speed of the moving object. When the moving body is the head 2a, the head speed is obtained, and when the moving body is a ball, the ball speed (initial speed) is obtained. As this specific calculation algorithm, for example, various calculation algorithms can be used in addition to the technique disclosed in JP-A-6-86845.

  Furthermore, in order to specialize in the speed measurement of the head speed during the swing of the golf club in this apparatus, the speed data from the start to the end of the swing is temporarily stored, and then the maximum speed of the swing is calculated from the stored data. Good.

  Further, when only swinging without placing the ball, the microcontroller 14 can easily obtain the head speed by the above-described known algorithm. Furthermore, in this embodiment, when the ball is actually hit, the microcontroller 14 obtains the ball speed and the head speed at the same time. This is because the moving speed of the head 2a accompanying the swing of the golf club 2 gradually increases from the start of the swing, reaches a maximum speed before and after hitting the ball, and then gradually decreases. On the other hand, since the ball B remains stopped at the beginning of the swing of the golf club 2, the moving speed becomes 0, and the head 2a hits and strikes, so that the speed of the ball B increases. There is a difference between the peak of the speed change of the head speed and the peak of the speed change of the ball speed (the peak of the ball speed occurs with a delay). Therefore, since two speed peaks occur, each speed can be obtained. Specifically, for example, both speeds can be obtained using a technique such as JP-A-6-86845.

  Further, the ball speed is not limited to that obtained based on the Doppler pulse as described above. For example, a signal output from the amplifier 12 (a signal obtained by amplifying the Doppler signal output by the Doppler sensor 11) is A / The D-converted data may be separately stored in a memory, and may be calculated by performing frequency spectrum analysis (for example, fast Fourier transform (FFT)) on the A / D conversion data stored in the memory. The golf ball is small and far from the head. Even in the case of an input signal having a disadvantageous S / N ratio due to a small reflected wave due to a small reflected wave, the FFT disperses the noise component over the entire frequency by frequency decomposition, and the signal component is extracted as a line spectrum. A sufficient signal-to-noise ratio for analysis can be ensured.

  Moreover, it is preferable to start accumulation in the memory on condition that a swing is detected. In this way, there is no need to constantly accumulate, and the load required for memory update processing is reduced. At this time, the function for determining the swing may be determined as having occurred when the period of the Doppler signal based on the Doppler signal output by the Doppler sensor 11 is a periodic pattern corresponding to the swing of the golf club. The periodic pattern corresponding to the swing of the golf club is determined in advance based on the periodic pattern obtained by swinging various clubs with a large number of people and the periodic pattern obtained when the golf club is not swinging. Alternatively, for example, a periodic pattern corresponding to the user's swing may be learned and used.

  Further, the calculation of the ball speed is performed after the accumulation of the A / D conversion data for a predetermined period is performed after the accumulation in the memory is started, the accumulation of the A / D conversion data is terminated, and after the accumulation is completed, The frequency spectrum analysis may be performed on the A / D conversion data stored in the memory. The predetermined period may be a time required for measurement after the head hits the ball. In this way, the size of the storage area for the A / D conversion data required for the memory can be set to a constant value, and the size of the storage area for the required data can be reduced compared to a configuration in which data is always stored. be able to. Further, since the frequency spectrum analysis for the accumulated A / D conversion data is performed after the accumulation is completed, the ball is used with an inexpensive processing device having a lower processing capacity than the configuration in which the accumulation of the A / D conversion data and the frequency spectrum analysis are performed simultaneously. Speed can be measured accurately. The predetermined period may be about 100 ms to 200 ms, for example. For example, the memory can be composed of several kilobytes.

On the other hand, the meet rate can be obtained based on the head speed and the speed (initial speed) of the launched ball. In other words, the microcontroller 14
The meet rate is calculated by meet rate = ball speed / head speed.

  The estimated flying distance is obtained from the ball speed and the used club type when the ball is actually hit, and in the case of swinging, the flying distance is obtained from the head speed and the used club type. Specifically, a coefficient for the ball speed and a coefficient for the bed speed are set in advance for each club type (a table of club type-coefficients is provided), and a coefficient corresponding to the club type is set for the ball speed or the head speed. The value multiplied is taken as the estimated flight distance. The presence / absence of the ball may be designated manually by manual operation, or various sensors may be provided and automatically recognized by the apparatus.

  Further, when the mode select button B2 is “short-pressed”, it is possible to select a parameter or play style in each mode. In the measurement mode, the display parameter is selected by “short pressing” the mode select button B2. That is, as shown in FIG. 3, two columns of three-digit numerical display parts using 7 segments are prepared in the lower area of the display unit 15, with the upper row representing speed (head speed / ball speed) and the lower row representing “estimated flight”. Display either “distance” or “meet rate”. Therefore, three types of display patterns are available: “Head Speed & Estimated Flight Distance”, “Ball Speed & Meet Ratio”, and “Ball Speed & Estimated Flight Distance”, and when a club type other than putter is selected. By “short press” of the mode select button B2, either “head speed & estimated flight distance” or “ball speed & meet rate” are alternately selected. If a putter is selected, only “ball speed & estimated flight distance” is forced.

  The microcontroller 14 notifies the display unit 15 of the currently displayed type. That is, the upper row displays either “HEADSPEED” or “BALLSPEED”, and the lower row displays either “MEET” (for meet rate) or “DIST” (for estimated flight distance). .

  When the club select button B3 and the mode select button B2 are pressed at the same time, the microcontroller 14 switches the speed unit. Two types of speed display units prepared in the present embodiment are prepared: “m / s” (meter / second) and “mph” (mile / hour). The microcontroller 14 displays the selected speed display unit on the display unit 15.

The club select button B3 is a button for selecting and designating the club type in accordance with the club to be used. Thereby, the microcontroller 14 can calculate the estimated flight distance from the selected club type and information such as the head speed and the ball speed. Specifically, when the microcontroller 14 recognizes “short press” of the club select button B3, the microcontroller 14 circulates the club types in the following order.
“1W → 3W → 5W → 3I → 4I → 5I → 6I → 7I → 8I → 9I → W (Wedge) → Pt (Putter)”
Further, the microcontroller 14 selects the currently selected club type using “W, I, t and 7 segments” as appropriate in the club type display area on the upper right of the display unit 15 in accordance with the circulation of the club type. indicate. That is, when wood (1W, 3W, 5W) is selected, the number selected as “W” is displayed and the iron (3I, 4I, 5I, 6I, 7I, 8I, 9I) is selected. If “I” is selected, the number selected as “I” is displayed. If the wedge (W) is selected, only “W” is displayed and the pattern (Pt) is selected. Displays only “t” (P can be displayed together with 7 segments).

  This club type is selected in advance before the swing because it is used as a coefficient reference condition when calculating the estimated flight distance. When Pt (Patter) is selected, the unit of the estimated flight distance is automatically “m” (meter).

  The measurement result is stored in a memory in the microcontroller 14. Therefore, when the function button B4 is “short-pressed”, the microcontroller 14 reads out and displays the past history stored in the memory and obtains an average value of the past measurement results. Two modes of “average value display” to be displayed are switched and displayed. Further, when the mode select button B2 and the function button B4 are “long pressed” at the same time, all the history / scores of the measurement results up to that point are cleared.

  Here, “average value display” is performed as follows. When the function button B4 is pressed for a short time in the measurement standby state, the average value of the selected club type is displayed from the history (a maximum of 500 records) recorded in the memory in the apparatus. In this case, a logo “AVE.” Is displayed on the display unit 15.

  That is, for example, as shown in FIG. 5, the memory stores various characteristics obtained in the measurement mode as a table structure associated with the club type. If the ball speed is not required as in the case of swing, “0” is stored. Accordingly, various characteristics of the club type to be displayed selected by pressing the club select button B3 in the “average value display” mode are read, and an average value is obtained for each characteristic item. At this time, “0” is excluded from the average value calculation target. And about the item displayed with the display parameter selected by operation of mode select button B2, the microcontroller 14 outputs said calculated | required average value. If there is no button operation for a certain period (for example, 10 seconds), the display returns to the measurement standby display. Even when the average value is being displayed, if the swing is made, the measurement is performed immediately.

  These characteristics can be registered separately for each user by switching the user by a predetermined button operation. Thus, by providing the user switching function and selecting / registering the user to be used before swinging, various characteristics are registered in association with the selected user. If it does in this way, it can change and use by a plurality of users.

  The “history display” mode performs the following processing. That is, when the microcontroller 14 recognizes that the function button B4 is “short-pressed” in the average value display state, the microcontroller 14 stores the history (up to 500 records) recorded in the memory in the apparatus. Read up to 10 new items from the list and display them. At this time, the microcontroller 14 displays a “MEM.” Logo on the display unit 15. And about the item displayed with the display parameter selected by operation of mode select button B2, the microcontroller 14 outputs the said read log | history sequentially. If there is no button operation for a certain period (for example, 10 seconds), the display returns to the measurement standby display. Even if the history is being displayed, the measurement is performed immediately when swinging.

  On the other hand, when the microcontroller 14 recognizes that the mode select button B2 and the function button B4 are simultaneously “long pressed” during the average value display or the history display, the microcontroller 14 clears the history. Since the average value is calculated from the history data, the average value is also cleared by this operation.

  Next, the “training mode” will be described. The training mode assumes a virtual golf course and goes around the virtual course as if it were a game. There are “full round” that turns 1 to 18 holes in one set, and “hole designation” that is completed with an arbitrarily designated hole. . In the training mode, when the mode select button B2 is “short-pressed”, the microcontroller 14 selects a play style of “full round” or “hole designation”. In this embodiment, since 18 holes are prepared, the hole number to be actually played in the hole designation is also designated using the mode select button B2. That is, each time the mode select button B2 is pressed for a short time, “Full Round” → “Hole Designation (No. 1)” → “Hole Designation (No. 2)” → …… “Hole Designation (No. 18)” → “Full Round” → ... and so on. Of course, when the mode select button B2 is pressed shortly, “full round” and “hole designation” are alternately switched, and the designation of the hole number to be played in “hole designation” is performed by another operation (for example, the function button B4 (Short press) may be performed. When the mode select button B2 is pressed for a long time, the microcontroller 14 switches to the measurement mode.

  When the club select button B3 is pressed for a short time, the microcontroller 14 selects a club type as in the measurement mode. If the club select button B3 is pressed for a long time, it is re-stroked.

  When “Full Round” is selected, if the function button B4 is pressed for a short time, the microcontroller 14 displays the score up to that point. If the button is pressed for a long time, the microcontroller clears the score and ends halfway. And

  In addition, the course layout of the virtual course (for all 18 holes) used in the training mode is stored in the memory (internal memory / detachable external memory (recording medium)) of the speed measuring device 10 and displayed on the display unit 15. Although it may be displayed, considering the reduction of the memory capacity and the display function of the display unit 15, the course layout table is placed in a booklet such as an instruction manual and the user looks at it and confirms it. Anyway. In this embodiment, the golf course map (course layout) is based on paper. That is, the information presenting means for showing the course layout to the user is a paper medium separated from the speed measuring device 10. One example of the layout of one hole is the hole layout shown in FIG. And a user advances a game based on the layout figure of the hole to play. Moreover, the hole on the software memorize | stored in the speed measuring apparatus 10 has divided each zone according to distance simply, as shown in FIG.

  In this training mode, the map data of the virtual golf course (course) stored in memory (distance from tee ground to cup, position of penalty zone such as OB / water hazard, etc.) is read, and the golf club swings. The estimated flight distance is calculated from the head speed or ball speed, the remaining distance to the cup is obtained, and the obtained remaining distance and the number of hits so far are displayed on the display unit 15, and finally the cup-in (remaining distance is the threshold). It is repeated until the value becomes less than or equal to).

  That is, the microcontroller 14 calculates the estimated flight distance based on the head speed or the ball speed, and blinks and displays the head speed or ball speed and the estimated flight distance on the display unit 15. Further, the estimated flying distance calculated from the remaining distance is subtracted to obtain the remaining distance, and the number of hits is added by “1 stroke”. The microcontroller 14 displays the obtained remaining distance and the number of hits on the display unit 15 after a predetermined time (for example, after 3 seconds). If the ball stop point (the next ball shot position) obtained by adding the estimated flight distance to the current position is a penalty area such as a water hazard or OB, the microcontroller 14 indicates the remaining distance to indicate that it is a penalty area. After blinking for a few seconds or displaying a predetermined mark on the display unit 15, a penalty is added to the number of strokes and the remaining distance is corrected, and the corrected number of strokes and remaining distance are displayed. When entering the water hazard, the remaining distance is obtained by setting the boundary position on the tee ground side of the water hazard to the shot position of the next ball and calculating the distance from there to the cup. Further, when the ball enters the OB zone, the previous shot position is set as the next shot position, and the distance from there to the cup is set as the remaining distance after correction. That is, the remaining distance at the time of the previous shot (the distance obtained by adding the estimated flight distance associated with the previous shot to the current remaining distance) is the remaining distance after correction.

  When the point where the ball falls is a green area (green-on), the microcontroller 14 lights the “NICE ON” logo on the display unit 15. On the green, the unit of distance is changed from “yard” to “m” (meter).

  Furthermore, when the remaining distance becomes 1 m or less, it is regarded as a cup-in, and the microcontroller 14 performs display for expressing the cup-in on the display unit 15 for several seconds. Further, when the remaining distance is in the range of 1 to 3 m, “OK” (hole out with one hit plus) is set, and the microcontroller 14 displays the OK on the display unit 15 for several seconds.

  The microcontroller 14 writes the above characteristics (club type, head speed, ball speed, meet rate) stored in the memory in the microcontroller 14 to the micro SD memory card. The micro SD memory card is taken out and set in a memory card reader or the like connected to a personal computer (PC), and the stored characteristics data is transferred to the PC. In this transfer, an application (golf support system) for managing various characteristics installed in the PC is activated and captured on the application. The data structure of various characteristics stored in the PC memory (external storage memory / internal storage memory) can be the same as that shown in FIG. When the characteristics registered in the micro SD memory card are registered separately for each user, the data of the characteristics stored in the memory of the PC are also registered separately for each user. As a result, the history display described below can be switched for each user. In this embodiment, the measurement results and the like are temporarily stored in the memory in the microcontroller 14 and written to the micro SD memory card by a predetermined button operation. You may make it write out.

  The golf support system mounted on the PC has a function of reading the data of various characteristics stored in the storage device of the PC and displaying the data on the monitor screen of the PC. Of course, you can also print out.

  7 to 12 show examples of layouts displayed on the monitor screen. As shown in the figure, a menu button area MB for selecting various characteristics to be displayed is prepared at the upper left of the display screen W. The user operates a pointing device such as a mouse linked to the PC and clicks and designates a predetermined menu button MB to output a corresponding display screen.

  For example, when a “head speed” button is clicked, a “head speed display screen” having a display layout as shown in FIG. 7 is output. That is, the MPU of the PC reads out the head speed history information among the characteristics stored in the memory in association with the club type, and groups them by club type. Then, the maximum / minimum head speed value is extracted for each group, the average value is obtained for each group, and the extracted and calculated results are displayed in a tabular first display window W1 prepared on the left side of the screen. Output. The individual head speeds are displayed in a second display window W2 in the form of a graph prepared on the right side of the screen. As is apparent from the figure, the second display window W2 draws a mark M at a corresponding position on the graph for each acquired head speed in a graph where the horizontal axis is the club type and the vertical axis is the head speed. Is. Further, between the first and second display windows W1 and W2 (outside of the vertical axis of the second display window W2), the head speed level for the club type (driver: 1 W in the figure) is set to “Pro Grade”, “ The display is divided into four levels: “Amateur Top Level”, “General Male”, and “General Female”. For the selected club type (driver), the corresponding area is also divided in the bar graph format in the second window W2. In this level division, the boundary is not necessarily divided firmly, so the boundary may not be divided by a line but may be appropriately blurred like a gradation.

  By adopting such a display layout, the user can display his / her own history so that the head speed when swinging the clubs of each club type, the degree of variation, and which class (rank). This is preferable because it can be easily recognized visually.

  When the “ball speed” button is clicked, a “ball speed display screen” having a display layout as shown in FIG. 8 is output. In other words, the MPU of the PC reads the ball speed history information among the characteristics stored in the memory in association with the club type, and groups them by club type. The read individual ball speeds are displayed in a third display window W3 in the form of a graph prepared on the screen. As is apparent from the figure, the third display window W3 draws a mark M at a corresponding position on the graph for each acquired ball speed in a graph in which the horizontal axis is the ball speed and the vertical axis is the club type. Is. Further, "general male", "amateur top level", and "professional grade" are displayed at predetermined positions in the upper column of the third display window W3. This is an indication of the approximate ball speed of the person of each class, and is displayed within the range of the corresponding ball speed. However, since the ball speed of each class person is not uniformly divided, no boundary line is provided.

  By adopting such a display layout, the user can display his / her own history so that the ball speed when hit with a club of each club type, the degree of variation, and which class (rank) is. This is preferable because it can be easily recognized visually.

  FIG. 9 shows another display layout of the “ball speed display screen”. In this display example, the ball speed is displayed in a circular meter format for each club type. That is, an arc-shaped meter portion is formed in a predetermined angle (270 degrees in the figure) along the circumference, and three needles extending in the circumferential direction from the center of the circle are drawn. These three needles indicate the maximum value / average value / minimum value of the ball speed for each club type. In the figure, for the sake of convenience, the maximum value: 60 m / sec, the average value: 50 m / sec, and the minimum value 40 m / sec are set for all the club types. Of course, drawing is performed as shown, and the average value does not always come between the maximum value and the minimum value due to variations in ball speed. In this example, a mark for identifying the club type (head picture + text number) is drawn at a predetermined position (downward) inside the circle, but this may also be provided outside the circle. There may be no picture. Further, since the arc-shaped meter portion has a certain width, for example, areas corresponding to “general male”, “amateur top level”, and “professional grade” shown in FIG. You may make it understand by changing a pattern, and in that case, the boundary of each area | region may be isolate | separated clearly, and a boundary etc. may be blurred using gradation etc. FIG.

  When the “meet rate” button is clicked, a “meet rate display screen” having a display layout as shown in FIG. 10 is output. That is, the MPU of the PC reads out the history information of the meet rate among the characteristics stored in the memory in association with the club type, and groups them for each club type. The individual meet ratios belonging to the group of the club type designated by clicking on the club selection menu window W6 are displayed in the fifth display window W5 prepared at the center of the screen. Further, the selected club type can be known because the corresponding area of the club selection menu window W6 is active (color / density is changed). When a different club type is selected from this state, the MPU acquires information on the meet rate for the selected club and draws a mark on the fifth display window W5.

  The fifth display window W5 is a window for visually displaying the meat rate on the golf club head. That is, the meat rate is plotted at a position proportional to the distance from the vicinity of the center of the head. The position proportional to the center of the head may be on the circumference of a circle or ellipse. It may be plotted as a dot at a random position on the circumference, or may be plotted as a line (ellipse or circle) itself on the circumference. As a result, when the meet rate is high, it is plotted near the center of the head, whereas when the meet rate is low, it is plotted at the periphery of the head. You can grasp your own meet rate.

  The club head drawn in the fifth display window W is preferably changed according to the club type (wood / iron, etc.). Furthermore, the club head can be set to be related to the user's actual club. In other words, for example, you can capture and set the club head photos taken by the user, and you can download and set photos and diagrams stored on a server on the Internet by the club vendor. You may be able to do it.

  In this figure, the fourth display window W4 prepared on the left side of the display screen displays the maximum / average / minimum values for each club type for the head speed, as in FIG. By doing so, it becomes easier to recognize the correlation between the head speed and the meet rate. That is, “Head speed is fast, but the meet rate is low, and as a result the flight distance is not very high”, or “Slow head speed is high but the meet rate is high, so a reasonable flight distance is obtained (fly straight)” , "Because the head speed is high and the meet rate is high, the flight distance is long."

  Of course, the data displayed in the fourth display window W4 may be data on the meet rate. That is, the MPU extracts the maximum / minimum meet rate value for each group, obtains an average value for each group, and outputs the extracted and calculated result to the tabular fourth display window W4.

  When the “estimated flight distance” button is clicked, an “estimated flight distance display screen” having a display layout as shown in FIG. 11 is output. That is, the MPU of the PC reads out the history information of the estimated flight distance from the characteristics stored in the memory in association with the club type, and groups them for each club type. Then, the individual estimated flight distances belonging to the group of the club type specified by clicking on the club selection menu window W9 are displayed in an eighth display window W8 prepared at the center of the screen. In the eighth display window W8, an estimated flight distance is taken on the horizontal axis, and a substantially parabola connecting both (the origin and the estimated flight distance) is drawn with the left end as the origin. FIG. 11 shows an example in which the estimated flight distance is 50, 75, 100, 150,..., 400 [yards].

  Further, the selected club type can be known because the corresponding area of the club selection menu window W9 is active (color / density is changed). When a different club type is selected from this state, the MPU acquires information on the estimated flight distance for the selected club, and draws a substantially parabola connecting the origin and the estimated flight distance in the eighth display window W8. Thus, by drawing a curve that images the flight trajectory of the ball like a parabola, the user can intuitively understand the length of the flight distance.

  Further, in this figure, in the seventh display window W7 prepared on the left side of the display screen, the maximum / average / minimum values for each club type for the head speed are displayed as in FIG. By doing so, it becomes easier to recognize the correlation between the head speed and the estimated flight distance. Of course, the data displayed on the seventh display window W7 may be data on the estimated flight distance (maximum / average / minimum for each club type).

  FIG. 12 shows another display layout of the “estimated flight distance display screen”. In this display example, the display form of the estimated flight distance displayed in the eighth display window W8 is changed. That is, in this example, in the graph in which the horizontal axis is the club type and the vertical axis is the estimated flight distance, each estimated flight distance acquired by the MPU of the PC is drawn at a corresponding position on the graph. .

  On the other hand, in the present embodiment, the user who sees the meet rate display screen shown in FIG. 10 can determine and register the target meet rate (reference meet rate). In addition, the range of the standard meet rate that can be set is “1.20 to 1.60”. Specifically, in response to an instruction from the user (operation of a PC input device (keyboard, pointing device)), the setting screens shown in FIGS. 13 and 14 prepared by the golf support system mounted on the PC are displayed. . Note that the values described in these figures are initial setting values (default values). Specifically, this instruction can be specified by operating a menu screen (not shown) prepared on the display screen, or by operating the pointing device on any display screen and right-clicking to display a pull-down menu. Various methods can be taken, such as selecting from there.

  When the display of the setting screen is selected, first, as shown in FIG. 13, a screen for registering the time setting is displayed. Click and select the “coefficient” tag displayed in the list, Switch to the coefficient setting screen shown in FIG.

  Then, in the “Nice Shot Coefficient” input area, operate the pointing device and click the triangle up / down key to increase / decrease the reference meat rate value or enter the value directly. You can specify the meet rate. Further, as is apparent from FIG. 14, the coefficient for multiplying the head speed and the ball speed when calculating the flight distance can be changed. Further, as shown in FIG. 13, the display time of each can be changed and set. Then, when the “Save” button is clicked on any screen, the setting contents such as the reference meat rate are written in the micro SD memory card set in the PC.

  Then, the micro SD memory card in which the conditions such as the reference meat rate are written as described above is taken out, and the micro SD memory card is inserted into the speed measuring device 10 in which the power is turned off, and the power button B1 and the mode select button are inserted. When the speed measuring device 10 is turned on by pressing and holding B2, the nice shot determination threshold is set to this reference meet rate.

  The reference meat rate is set by transferring the setting on the PC side to the speed measuring device 10 as described above, but the input device (setting button) provided in the speed measuring device 10 is operated as appropriate. Then, it may be set directly. Moreover, what was previously set to the speed measurement apparatus 10 as an initial value can also be utilized.

  The microcontroller 14 of the speed measurement device 10 obtains a nice shot display on the LCD of the display unit 15 when the meet rate exceeds the set reference meet rate as a result of obtaining the measured meet rate at the time of swing. . With such a mechanism, it is possible to easily set a goal that suits you, and during practice you can immediately check whether you have reached the goal on the spot. Therefore, training toward the target can be easily performed.

  As described above, in the present embodiment, the target meet rate can be determined and set by itself, and when the target meet rate is exceeded, a nice shot is displayed, so that a nice shot is displayed. The swing can be devised and improved. In this way, goals can be set according to the level of each person. Therefore, training can be performed while gradually increasing the target meet rate. In addition, since it will be displayed after measurement, you can immediately check whether you have reached the target.

  In this embodiment, the nice shot is output by, for example, turning on a mark indicating a nice shot, separately providing a lamp such as an LED, and lighting / flashing it, or a sound indicating “nice shot”. (Sound etc.) may be output.

  In addition, although the setting of the reference meet rate is performed, in the present embodiment, a setting screen is displayed and a numerical value is input. However, the present invention is not limited to this, and is drawn in, for example, the fifth display window W5. By clicking an arbitrary position in the figure of the head of the golf club being clicked, the meet rate at the clicked location may be set as the reference meet rate. In this way, it is easy to set an appropriate reference meat rate that should be a target visually and intuitively while observing how the actual meat rate varies.

  In addition to the virtual round mode that goes around the virtual golf course as described above, for example, a challenge mode may be provided as the training mode. In the challenge mode, a flight distance that the golfer 1 should aim at is randomly displayed on the display unit 15, and the golfer 1 selects a club and swings aiming at the flight distance. Then, the flight distance is calculated from the measurement result of the swing and displayed on the display unit 15. In this way, the player can know the difference between the two displayed flight distances, and can practice swinging to obtain the target flight distance. Also, a nice-on display is performed when the estimated flight distance based on the measurement result and the flight distance to be challenged are within a predetermined range. In this way, it is possible to enjoy the practice of performing a swing corresponding to the flight distance to be challenged. The range of the upper and lower limits can be set on the setting screen shown in FIG.
