In the present invention, the pressure data for the four postures most important in the swing motion is automatically extracted from the pressure data continuously input in response to the reception of the first to fourth position signals M1-M4.

In general, the address posture is set equal to the load applied to both feet by about 1/2, and in this case, the first to third pressure sensors 11a-11c of the first and second transmitters 10 and 20, respectively. The addition values P _L = P1 + P2 + P3 and P _R = P11 + P12 + P13 of the three pressure voltage signals P1-P3 and P11-P13 detected from, 21a-21c are obtained approximately equal to each other. . Thus, the load on the left and right feet is equally applied by about 50%, as shown in FIG. 11B.

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. 9 to 11D.

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, S4).

Subsequently, before the user enters the address posture, the power switch (not shown) for the third transmitter 70 is turned ON, and when the user enters the address posture (S5), the first and second transmitters ( 10 and 20 The first to third pressure voltage signals P1 to P3 and P11 to P13 are continuously detected from the first to third pressure sensors 11a to 11c and 21a to 21c, respectively. 3 After amplification and waveform correction are performed in the amplifiers 12a-12c, they are input to the CPU 13.

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 (S6).

In this case, the data format used for the transmission of the pressure data consists of, for example, 6 bytes. That is, the first byte is an ID code (per device group) used to identify a transmitting device, the BIT0 and BIT1 are the device number, the BIT2 and BIT3 are status display bits, the BIT4-BIT7 is an additional extension bit, and the second byte of the second byte. 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.

Then, when the user backswing from the address posture, the output voltage of the first posture detection sensor 71a of the third transmitting device 70 is switched from "H" to "L", and the CPU 73 is lowered when the level is changed. The signal is detected as a first position signal M and modulated at high frequency through the RF transmitter 76, and then wirelessly transmitted to the receiver 30 by serial data communication (S7).

On the other hand, the receiving device 30 is the first to third to be capable of receiving at the same time the pressure data transmitted from the first to third channels (CH1-CH3) consisting of the first to third transmitters (10, 20, 70). 3 RF receivers 32a-32c are provided.

The first to third RF receivers 32a to 32c respectively transmit the modulated high frequency signals transmitted from the first to third channels CH1 to CH3 of the first to third transmitters 10, 20 and 70. 33, received through the antenna 31 by serial communication, converted to a low frequency signal through multi-step frequency downconverting, and then digital data in a demodulation method corresponding to the modulation method of the transmitter. Or outputs an analog signal (S8).

When the analog signal is designed to be output from the first to third channels CH1-CH3, the first and second channels CH1 and CH2 of the first and second channels, which are digitally converted by the D / A 38, are converted into digital signals. The RAM 35 stores the first to third pressure data P1-P3 and P11-P13 and the first position signal M1 of the third channel CH3.

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, it is determined whether the first position signal M1 transmitted from the third transmitting device 70 is received through the third channel CH3 according to the start of the backswing of the user (S12). First to third pressure data P1 to P3 and P11 to P13 of the first and second channels CH1 and CH2 that have been extracted, and at the same time between the first and second addition values P _{L and} P _R. The percentage value of is calculated, and the extracted pressure data and the percentage value are stored in the RAM 35 as the motion 1 of page 1 (S13).

At the same time, the CPU 33 outputs a control signal to the camera controller 81, causing the camera controller 81 to operate the CCD camera 80, and as a result, the swing motion of the user received through the CCD camera 80. Image data is extracted and stored in the RAM 35 in motion 1 of page 1 (S13).

Subsequently, when the user starts downswing from the back swing position, the second position signal M2 is generated from the third transmitting device 70. Therefore, when the second position signal M2 is received by the receiver 30, the pressure data P1-P3 and P11-P13 at this time are extracted and the first and second addition values ( P _L, P _R ) to calculate the percentage value, and to store the extracted pressure data and the percentage value as the motion 2 of page 1, and at the same time to extract the image data of the user's swing motion from the CCD camera 80 page It is stored in motion 2 of 1 (S14, S15).

Then, when the user starts the downswing and reaches the impact moment of the golf ball, the third position signal M3 is generated from the third transmitting device 70. Therefore, when the third position signal M3 is received by the receiving device 30, the pressure data P1-P3, P11-P13 at this time are extracted and the first and second addition values ( P _L, P _R ) to calculate the percentage value, and to store the extracted pressure data and the percentage value as the motion 3 of page 1, and at the same time extract the image data of the user's swing motion from the CCD camera 80 page It is stored in motion 3 of 1 (S16, S17).

Subsequently, when the user reaches the follow swing position through the downswing, the fourth position signal M4 is generated from the third transmission device 70. Therefore, when the fourth position signal M4 is received by the receiver 30, the pressure data P1-P3 and P11-P13 at this time are extracted as described above, and the first and second addition values ( P _L, P _R ) to calculate the percentage value, and to store the extracted pressure data and the percentage value as the motion 4 of page 1, at the same time to extract the image data of the user's swing motion from the CCD camera 80 page It is stored in motion 4 of 1 (S18, S19).

Thereafter, when the user makes a swing operation twice to five times in the same manner as in the above steps (S12-S19), the pressure data is extracted and the percentage value is calculated based on the swing data. The data is extracted through the CCD camera and stored in pages 2 to 5 provided in the RAM 35 (S20).

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. -P3, P11-P13 and the percentage value and the image data between the first and second addition values (P _L, P _R ) are output to the LCD controller 37, the LCD controller 37 respectively from the built-in ROM The left / right load distribution patterns 51 and 52 corresponding to the pressure data P1-P3 and P11-P13 are read out and output to the display device 50 together with the percentage value and the image data (S21).

FIG. 10 shows an example of a graphic display of the display device 50 when the user selects the motion 1 of the page 1 by the page selection switch 36b and the motion selection switch 36c in the receiving device 30. In this case, the load distribution applied to both feet is represented as 50%: 50%, and the motion of the user at this time is displayed as a still image 83 by the image data.

In the example shown in Figs. 11A to 11D, the pressure on the front part 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. 11A are graphics after the initialization process, and FIG. 11B is a graphic when the first position signal M1 is received. The load distribution applied to both feet is approximately 50:50. In this case, the load distribution on 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.

11C shows, for example, the left / right load distribution patterns 53 and 54 when the second position signal M2 is received, and a load is applied to the left foot and the right foot at a ratio of 40:60, and the front of the right foot is shown. Has a very heavy load, and almost no load is applied to the rear of the left foot.

FIG. 11D shows the left / right load distribution patterns 55 and 56 at the moment when the golf ball is impacted by the head, and the load is applied to the left and right feet at a ratio of 70:30, and the front and rear of the left foot are almost all of users. The load is applied and almost no load is applied to the front and rear of the right foot.

Therefore, the user is applied to the left and right load distribution patterns 51-56 for each time, that is, motions 1 to 4 of each page, while referring to data recording the flying distance and the direction in which the golf ball flew, and the like. By analyzing the load ratio and the swing motion at this time through the still image, it is easy to determine what is wrong with his posture.

Furthermore, the EPROM 34 stores in advance the ideal left / right load distribution patterns such as tee shots and drive shots and data on the still images of the swing motions. You can compare it with your posture.

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 posture. Done.

On the other hand, if 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 (S22). S23).

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

In the above embodiment, serial communication is used as an example of data communication. However, when there is a large amount of data to be transmitted from a transmission device, 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. Differential display of concentric circles is possible, and any display can be performed as long as the graphic process can grasp the magnitude and distribution of load.

In addition, the above embodiment has been described with respect to the swing motion related to the golf exercise, for example, but in addition to golf, various sports motions such as baseball, tennis, etc. that require a continuous motion change from a plurality of pressure sensors installed on both shoes The pressure data (load distribution data) obtained and the image data at this time can be used to correct one's posture.

As described above, in the present invention, in particular, the motion change by a plurality of pressure sensors installed on both shoes during the various sports operation that hits the ball by using a tool such as golf, baseball, tennis, etc. and requires continuous motion change in the stationary state According to the measurement, the distribution of the load applied to the front and rear of the feet and the change of the operating load are precisely measured along with the corresponding image data and quantitatively analyzed or compared with the ideal motion to quickly and effectively correct their own motion. Can be.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and is not limited to the spirit of the present invention. Various changes and modifications can be made by those who have
