The load distribution on the front (i.e., big toe and little toe) and rear (i.e., heel) of each of the left and right feet, and the left and right loads in which the size of the unit pattern 5 is changed according to the size of the load. A microprocessor (CPU) 33 for generating an output signal to the LCD controller 37 so as to graphically display the distribution patterns 51 and 52 and at the same time display the distribution ratio of the loads on the left and right feet; The CPU 33 includes a ROM in which a plurality of pattern data having different sizes of the unit pattern 5 are embedded in the same pattern shape. And an LCD controller 37 for outputting graphic data to the LCD display device 50 so as to display load distributions applied to the front and rear sides of the left and right feet according to the output signal in a pattern proportional to the magnitude of the load.

In addition, the receiver 30 has an LCD display 50 disposed on the front of the housing 40, and three reset switches, page selection switches, and motion selection switches 36a-36c and a power switch (at the lower end thereof). ON / OFF) 45 is arranged.

The reset switch (RESET) 36a is a switch for clearing the RAM 35 to initialize the motion data value of each page, and the page select switch (PAGE) 36b is an example. For example, a switch for sequentially selecting five pages corresponding to five swing motions, and a motion selection switch (MOTION) 36c may include three detailed postures, for example, an address posture, for the operation of each selected swing motion. It is a switch for selecting by dividing the moment to impact the golf ball by the back swing posture, and down swing.

Data of pages 1 to 5 corresponding to five swing motions are displayed according to the operation of the page selector switch 36b, and address posture, backswing attitude, and, according to the operation of the motion selector switch 36c on each page. Data of any one of motions 1 to 3 corresponding to the moment when the golf ball is impacted by the down swing is displayed.

For example, the RF transmitter 16 of the transmitters 10 and 20 and the first and second receivers 32a and 32b of the receiver 30 are, for example, the TXH series transceivers of JS TECH. It can also be configured using the module "TXH-900M". In this case, the operating frequency is in the 902-928MHz band, the operating range is 1/4 mile, and each can be configured as a single chip.

The RAM 35 may be configured as a five-stage shift register to record five swing motions. If the data for the sixth swing motion is input and stored, the first swing motion data stored first is It is deleted. That is, data is recorded in a first-in first-out (FIFO) manner.

In the present invention, pressure data for the three most important postures, for example, the address posture, the backswing posture, and the golf ball impact posture, are automatically extracted from the continuously input pressure data.

That is, the address posture is extracted data when the loads applied to both feet are equally set by 1/2, and in this case, the first to third pressure sensors of each of the first and second transmitters 10 and 20 ( The sum of the three pressure voltage signals P1-P3 and P11-P13 detected from 11a-11c, 21a-21c (P _L = P1 + P2 + P3, P _R = P11 + P12 + P13) is the same. Obtained. Therefore, the loads applied to the left and right feet are equally applied by 50% as shown in FIG. 7B.

Subsequently, when changing to the back swing position, the load applied to the left foot and the right foot is generally applied at a ratio of 40:60, as shown in FIG. 7C, and is optimal when the load on the right foot is the maximum value, that is, when the peak value P _R is the peak value. Recognize it as a backswing position and extract the pressure data at this time.

In addition, the load applied to the left foot and the right foot at the impact of the golf ball is changed at a ratio of 70:30 as shown in FIG. 9D, and the impact when the load applied to the left foot is the maximum value, that is, the peak value PL is the peak value. Recognize the moment and extract the pressure data at this time.

The transmitters 10 and 20 and the receiver 30 of the present invention each use separate batteries as power sources 60 and 60a for supplying a driving voltage.

Hereinafter, the operation of the motion load distribution measuring system of the motion motion according to the present invention configured as described above will be described in detail with reference to FIGS. 4 to 7.

First, when the power switch (ON / OFF) 45 of the receiver 30 is turned on, the system is initialized according to the initialization routine of the control program stored in the EPROM 34 to clear the RAM 35 and the like. Various variable values are set using the stored numerical values (S1, S2).

Subsequently, when the user wants to measure the distribution of the operating load for the swing motion while the system is operating, the reset switch 36a is operated. Then, the data stored in the RAM 35 until then is cleared and initialization is performed. (S3).

Subsequently, when the user enters the address posture, the first to third pressure voltage signals (1a to 3c) from the first to third pressure sensors 11a-11c and 21a to 21c of each of the first and second transmitters 10 and 20 are applied. P1-P3 and P11-P13 are continuously detected and input to the CPU 13 after amplification and waveform correction are performed in the first to third amplifiers 12a-12c, respectively.

The received first to third pressure voltage signals P1-P3 and P11-P13 are converted into digital first to third pressure data P1-P3 and P11-P13 by the built-in A / D 18. After that, it is stored in the RAM 15. The pressure data stored in the RAM 15 is modulated at high frequency by the RF transmitter 16 and then wirelessly transmitted to the receiver 30 by serial data communication (S7).

In this case, the data format used for the transmission of the pressure data is composed of 6 bytes as shown in FIG. That is, the first byte is an ID code (per device group) used to identify a transmitting device, the BIT0 and BIT1 of the second byte are the device number, the BIT2 and BIT3 are status display bits, and the BIT4-BIY7 are additional extension bits. 3 bytes indicates converted pressure data of the first pressure sensor 11a, 4 bytes indicates converted pressure data of the second pressure sensor 11b, 5 bytes indicates converted pressure data of the third pressure sensor 11c, The sixth byte indicates data for error detection, respectively.

On the other hand, the receiver 30 is a pair of first and second to simultaneously receive the pressure data transmitted from the first and second channels (CH1, CH2) consisting of the first and second transmitters (10,20) 2 RF receivers 32a and 32b are provided.

The first and second RF receivers 32a and 32b respectively output the modulated high frequency signals transmitted from the first and second channels CH1 and CH2 of the first and second transmitters 10 and 20, respectively. According to the control of the digital signal received through the antenna (31a, 31b) through the serial communication to convert the low-frequency signal through the frequency downconverting (multilevel downconverting) and then demodulation method corresponding to the modulation method of the transmission device digital data Or outputs an analog signal (S8).

When the analog signal is designed to be output from the first and second RF receivers 32a and 32b, the digital signal is converted by the D / A 38 into a digital signal, and the first and second channels CH1 and CH2 The first to third pressure data P1 to P3 and P11 to P13 are stored in the RAM 35.

The CPU 33 then determines whether its ID code stored in the EPROM 34 and the ID code of the received data match (S9).

If the ID codes match, the data received continuously is received. If the ID codes do not match, the first and second RF receivers 32a and 32b are controlled to give up the subsequent data reception, and the RAM is already The data stored in 35 is deleted.

Next, the CPU 33 adds the first addition value P obtained by adding the first to third pressure data P1-P3 of the first to third pressure sensors 11a-11c of CH1 stored in the RAM 35. _L ) and the second addition value P _{R obtained} by adding the first to third pressure data P11-P13 of the first to third pressure sensors 21a-21c of CH2 are calculated (S10).

On the other hand, the load distribution patterns 51 and 52 which are graphically displayed on the display device 50 have a small size of the unit pattern 5 in the case of light weight on the basis of the standard user having a specific weight, and a unit pattern in the case of heavy load. The magnitude of the load in (5) is indicated in such a way that the magnitude of the load applied to the front and rear of both feet in each operation is indicated.

Therefore, when the first addition value P _L of CH1 and the second addition value P _R of CH2 coincide for the first time, the extracted addition values P _{L and} P _R are proportional to the user's weight. One value is obtained. And extracts the correction values required to apply the load distribution patterns 51 and 52 of the user from the standard value obtained by adding (P _L, P _R) compared with the addition value (P _L, P _R), the standard user and stores them (S11).

The pressure data obtained in proportion to the user's weight received later in accordance with the swing motion by storing the correction value is light to medium-weight based on the pressure data corrected regardless of the user's weight by using the correction value. Graphic display can be made.

Subsequently, the first and second addition values P _{L and} P _R are compared with each other, and when P _L = P _R , the user is determined to be in an address posture. Simultaneously extract P3, P11-P13, calculate the percentage value between the first and second addition values P _{L and} P _R , and store the extracted pressure data and the percentage value as motion 1 of page 1 ( S12).

Subsequently, when the user reaches the back swing position, the second addition value P _R reaches the peak value. Therefore, at this time, it is determined that the user is in the back swing position, and at this time, the pressure data P1-P3 and P11-P13 are extracted and the percentage value between the first and second addition values P _{L and} P _R is determined. The calculated pressure data and percentage values are stored in Motion 2 on page 1.

Subsequently, the CPU 33 applies an output signal for about 2 sec to the buzzer controller 41 and the motor controller 43 after a set time, e.g. after 0.8 sec, from the motion 2, and causes the buzzer 42 and the vibration motor 44 to operate. By operating it informs the user that the backswing position has been reached (S13).

Then, when the user starts the downswing and reaches the moment of impact of the golf ball, the second addition value P _R reaches the peak value. The CPU 33 determines that the head of the club and the golf ball are at the moment of impact, extracts the pressure data (P1-P3, P11-P13) at this time, stores them as motion 3 of page 1, and simultaneously stores the first and second. The percentage value between the addition values P _{L and} P _R is calculated to store the extracted pressure data and the percentage value as the motion 3 of page 1 (S14).

Subsequently, when the user makes a swing operation twice to five times in the same manner as in the step S5-S14, the pressure data for this is extracted and the percentage value at this time is obtained and stored in page 2-page 5 (S15). ).

Thereafter, when the user finishes five swing operations and selects the page selector switch 36b and the motion selector switch 36c of the receiver 30, the CPU 33 transmits the corresponding pressure data P1 stored in the RAM 35. A percentage value between the P3, P11-P13 and the first and second addition values P _{L and} P _R is output to the LCD controller 37, and the LCD controller 37 receives respective pressure data from the built-in ROM. The left / right load distribution patterns 51, 52 corresponding to (P1-P3, P11-P13) are read out and output to the LCD display device 50.

In the example shown in FIGS. 7A to 7D, the pressure on the front portion of the two feet is not increased by the first pressure sensors 11a and 21a, respectively, without using the second pressure sensors 11b and 21b disposed in front of the feet. It is an example of measuring and displaying a load value based on this.

The left / right load distribution patterns 51 and 52 shown in FIG. 7A are graphics after an initialization process, and FIG. 7B is a case in which the user takes an address posture, and the load distribution applied to both feet is equal to each other at 50:50. In this case, the load distribution applied to the front and rear of the left and right feet may be different according to the posture of each user.

In this case, the unit pattern sizes of the front load distribution patterns 51a and 52a of the two feet are different from the unit pattern sizes of the rear load distribution patterns 51b and 52b according to the magnitude of the front and rear loads.

Fig. 7C shows, for example, the left / right load distribution patterns 53 and 54 in the backswing position, where a load is applied to the left and right feet at a ratio of 40:60, and a very heavy load is applied to the front of the right foot. In the rear of the left foot, almost no load is applied.

FIG. 7D shows the left / right load distribution patterns 55 and 56 at the moment when the golf ball is impacted by the head, and loads are applied to the left and right feet at a ratio of 70:30, and almost all of the users are in front and rear of the left foot. The load is applied and almost no load is applied to the front and rear of the right foot.

Therefore, when the user analyzes the left / right load distribution patterns 51-56 for each time, that is, the motions 1 to 3 of each page while referring to data recording the distance of each time and the direction in which the golf ball flew, etc. It is easy to determine if there is a problem.

Furthermore, the EPROM 34 stores in advance the data of the ideal left / right load distribution patterns such as each kind of shots, eg, tee shots, drive shots, etc., which beginners can select and compare with their postures. You can do that.

Also, if you store data about your posture and install a separate flash memory to recall it when you need it and view it again, professional golfers can use it when they fall into a slump and contrast it with their current form. Done.

On the other hand, when there are five or more swing motions in the system, that is, six swing motions are performed, the pressure data detected according to the six swing motions is stored on page 1 and the first stored pressure data is removed (S17). S18).

In addition, in the present system, as a result of securing sufficient memory capacity and a high speed signal processor, data collection for continuous swing posture and continuous posture analysis are performed by sampling and extracting pressure data obtained according to a swing motion at a predetermined time. It becomes possible.

In addition, it is also possible to easily connect the graphic data displayed on the display device with a host computer, store it, print it if necessary, or output it, or easily determine whether there is a change in one's posture by statistical processing of these data.

In the above example, serial communication is used as the data communication. However, when there is a large amount of data to be transmitted from the transmission apparatus, high-speed data processing is possible by using well-known parallel data communication.

Further, in the above example, it is only possible to receive data from the transmitting device to the receiving device in a unidirectional data communication method, but by controlling the transmitting device from the receiving device by duplex bidirectional communication, the reliability of the data communication and the Efficient operation control is possible.

Further, in the above embodiment, the distribution and strength of the loads can be known by changing the sizes of the plurality of unit patterns as the load distribution pattern. However, in addition to the graphic display method, for example, a plurality of unit patterns are proportional to the size of the loads.
