Load Data Transmitter for Use in System for Measuring Distribution of Dynamic Load in Athletic Sports}

The present invention relates to a load data transmission device for a motion load distribution measuring system of an athletic motion, and in particular, is installed in the sole of a user's shoe so that it can be easily replaced as needed, and according to the user's continuous motion change The present invention relates to a load data transmitting device for transmitting load data measured by an operating load distribution measuring system by precisely measuring a distribution of loads applied to front and rear portions of a and a continuous change in operating load.

In general, sports, such as golf, baseball, ping-pong, etc., in which continuous athletic motion is performed in a stationary state, a form, in particular, continuous athletic motion is very important. In particular, sports that adults can enjoy as a hobby, such as golf, many people spend a lot of money and time to take the lessons of experts to learn the correct swing posture.

In addition, golf or baseball's famous professional players often fall into a slump, most of which is due to the unintentional change of their swing form, so the videos of their prime time or other good players He is trying to reshape his changed swing form, either by watching videos or comparing and analyzing these videos with his current videos.

Furthermore, in golf, as a part of improving the handyman, a lot of swing and putting exercises and physical training are performed to improve the distance of the drive shot or to move the correct weight necessary to improve the accuracy of the putt.

However, the lessons of such experts are expensive and can take a lot of time because they must go to a specific place such as a golf driving range.

In addition, the method of correcting one's own motion using video is difficult for the general amateur and requires the help of a professional.

Moreover, the above calibration methods are all based on the experience of experts, but are not posture correction based on scientific and quantitative analysis.

In consideration of these problems, the present inventors analyze the distribution of loads applied to the front and rear of both feet and the continuous change of the operating load during various sports operations, and analyze them or perform an ideal exercise motion. In contrast, we have proposed a motion load distribution measurement system of motion motion that can correct one's own motion quickly and effectively by correcting it.

The first and second transmitters used in the measuring system are respectively installed on the insole of the left and right foot shoes of the user, and at least two or more pressures proportional to the load applied to the front and rear portions of the left and right feet during various sports operations of the user. The data is measured and transmitted wirelessly to the receiver of the system main body.

In this case, three piezoelectric piezoelectric elements, which are used as pressure sensors in the first and second transmitters, are respectively installed on the insole of the user's left and right foot shoes, and the pressure data measured from these sensors is transmitted to the main body by signal processing. When the transmitter main body is used inside or outside of the shoe, durability and reliability are inferior, and it becomes difficult for the user to replace the sensor and the transmitter main body conveniently when periodically replacing the sensor damaged by the user's load. .

Therefore, the present invention is conceived in view of the problems of the prior art, the purpose of which is installed so as to replace the shoe sole of the user can be easily replaced as needed, according to the continuous motion change of the user before and after both feet The present invention provides a transmitting device capable of precisely measuring a pressure value corresponding to a load that can indicate a distribution of load applied to a part and a change in a continuous operating load, and transmitting measured data to an operating load distribution measuring system.

In addition, although the embodiment shown in FIGS. 2A and 2B illustrates the use of radio wave communication having a long transmission distance and no directivity for data communication between the transmitter and the receiver, infrared light according to an infrared data association (IrDA) method is used. It is of course also possible to use a wireless communication interface. In this case, however, the transmission distance is short and has a directivity of 30 degrees or less. The difference is that an LED for radiating infrared rays is provided in the RF transmitter 16 instead of the antenna 17.

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 golf ball by the moment of impact 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 load applied to both feet is set equally by 1/2, in this case, the first to fourth pressure sensors of each of the first and second transmitters 10 and 20 ( The sum of the four pressure voltage signals P1-P4 and P11-P14 detected from 11a-11d, 21a-21d (P _L = P1 + P2 + P3 + P4, P _R = P11 + P12 + P13 + P14) Are obtained identically to each other. Therefore, the load on the left foot and the right foot is equally applied by 50%.

Afterwards, the load on the left and right feet is normally 40:60, and the optimal load is recognized when the load on the right foot is at its maximum, that is, when the peak value P _R is the peak value. To extract the pressure data.

Extract the data.

The transmitters 10 and 20 and the receiver 30 of the present invention each include power supply units 60 and 60a for supplying driving voltages using separate batteries.

In the motion load distribution measuring system of the exercise motion configured as described above, it is firstly important to accurately detect the pressure value proportional to the load according to the exercise motion of the user. However, since the first and second transmitters for detecting the pressure value have to withstand the load of the user, it is impossible to use them permanently. Must be replaced.

The first and second transmitters of the present invention considered such an ease of replacement and at the same time considered the correct transmission of the load to the pressure sensor and no abnormality when taking a motion motion while wearing the shoes (1, 2).

In this case, as shown in FIG. 5, the RF transmitter 16 is preferably embedded in the center of the front, and the signal transmitter 19 including the power supply battery is embedded in the center of the rear, respectively.

In addition, first and second pressure sensors 11a and 11b are embedded in the second substrate 72 integrally fixed to the front lower portion of the first substrate 71, and the first substrate 71 is embedded therein. The third and fourth pressure sensors 11c and 11d are embedded in the form of a plate in the third substrate 73 integrally fixed to the rear lower part of the substrate.

The second and third substrates 72 and 73 and the first substrate 71 have a plurality of through-holes 77 through which the plurality of fixing bolts 74 penetrate partially through the pressure sensor. The sole 3 is embedded with a plurality of stud nuts 76 which are fastened to the threads formed at the ends of the bolts at positions corresponding thereto.

In this case, preferably, the head of the fixing bolt 74 is provided with a recess 77a at the bottom of the through hole 77 to avoid friction with the ground, so that the head of the bolt is positioned inside the recess. It is preferable that a plurality of insulating rings 75 made of a non-conductive material are embedded in the second and third substrates 72 and 73 at portions of the pressure sensors 11a-11d through which 74 passes. In addition, the fixing bolt 74 is advantageous to prevent the loss of the fixing bolt is configured so that the front end portion is caught by the substrate (71-73) is not separated. However, it is not a problem that the fixing bolt is separated from the substrate.

In the above-described embodiment, the first to third substrates 71 to 73 made of different materials are used as the substrate, but the present invention is not limited thereto and may be configured using a material made of the same material as the sole. It is possible. In addition, the signal transmitter 19 including the battery may be installed in the middle portion of the substrate instead of the rear side.

Moreover, the present invention can be used not only for the correction of motion that starts at the stop motion of a sports game using tools such as golf clubs, bats, and rackets, but also for the continuous motion of a sports game without using such a tool or for a certain momentary posture correction. It is possible.
