Description of the Invention: [Technical Field] The present invention relates to a measuring device applied during exercise, particularly to a measuring device for swinging motion. [Prior Art] For the current measurement device for measuring the swing speed of a club, some have developed into a large volume. For example, the "sPorts analysis and testing system" patent of the US 5,868,578 is using several high-speed cameras to capture The action of the player, combined with computer image processing, to calculate the speed of the swing, this type of equipment is difficult to carry, and expensive, and it is inconvenient to use and difficult to popularize. Some measuring devices are installed on the ground, such as the "Electric Apparatus for use practicing a golf swing" patent No. 4, 979, 745, the "Gold swing measurement system" patent No. 5, 257, 084, and the "Gold swing analysis" of the US No. 6,375, 579. System and method" patent case. They use light to measure the speed of the club head. Although its size has been reduced and the price has been reduced, it is still inconvenient to carry, and it is necessary to carry out the erection before the replacement. Some measuring devices are directly embedded in the club. For example, the US Patent No. 3,945,646 "Athletic swing measurement system and method" patent, and the US Patent No. 6,648,769 "Instrumented golf club system & method of use" patent case. They are equipped with accelerometers in the club head to calculate the speed, force and other conditions. However, these measuring devices need to be installed at each club head, the cost will be not cheaper at 200826004, and because of the installation of these measuring devices, it is very likely that the original nature of the club will be changed. Bad influence. In addition, the measuring device can be independently formed into a single body and can be mounted on a glove or a club. For example, the U.S. Patent No. 5,688,183, "Vel〇 n^it〇ring system f〇r g〇lf dubs" patent. The acceleration is measured by the acceleration sensor (Acceleration Sens〇r) (to determine the angular velocity of the ball, and then further determine the speed F of the club, that is, as shown in equation (1). It is the distance from the center of rotation to the club head. < is the distance from the position of the accelerometer to the club head. v=Rh〇)=RhS· \Rs (1) However, because the sensitivity of the acceleration sensor itself is sensitive It may be a false trigger, even in an unshaked condition, which will result in a false trigger. The measured acceleration value 々 is - Absolute Value, that is, the obtained velocity value "accepts the error of the acceleration sensor itself (Error), affecting the accuracy of the measurement. Content] The purpose of this book is to provide a measuring device for swing motion, which can improve the accuracy of the measured value. Yu Yu, the measuring device for swing motion of the present invention is a ball The rod and t move 'the beta measuring device comprises a hollow housing', a geomagnetic sensing unit housed in the housing, and a processing unit accommodated in the housing to receive the output of the geomagnetic sensing unit And a display unit exposed outside the housing, the geomagnetic sensing unit can define a reference axis through itself, 200826004 can detect three mutually perpendicular independent axial %, and you are from less and z axial The magnetic field is continuously induced and calculated to be output through its own earth direction. The processing unit will be within a unit of time, the angle between the direction of the earth's magnetic field and the reference axis of the geomagnetic sensing unit: Change Μμ, in order to find the instantaneous angular velocity of the club, that is, (four) heart' can be obtained through ^^ to determine the specific instantaneous velocity on the club, where ^ is from the center of rotation to the position The center of rotation is the arm joint of the striker, and the display unit is for displaying the result calculated by the processing unit. - The function of Shuming is to use the geomagnetic sensing unit to know the angle θ ' per unit time of the club through the calculation of ^ / Θ / ,, to find the angular velocity ω of the club, because the two angles are 0 The difference is the relative value (Relative Value), which can avoid the error of the swing speed r being included in the measurement of the geomagnetic sensing unit itself, so that the obtained swing speed r value is more accurate. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. Before the present invention is described in detail, it is noted that in the following description, like elements are denoted by the same reference numerals. As shown in FIG. 1 and FIG. 2, the first preferred embodiment of the measuring device i for the swing motion of the present invention can be used to measure the physical quantity of a club 2 when swung, such as angle, angular velocity, speed, Distance, impulse, etc. In the present embodiment, the club 2 is a golf club and has a shaft 21 and a ball head 22 connected to one end of the shaft 21. But it can also be a baseball bat, stack 7 200826004 bat, hockey stick and other golf clubs.呑海测测装置1 is detachable and can be viewed by a hitter. Of course, :== in the hand... so that you can set it! Combined with the (four)-one of the shaft 21 of the club 2, in Fig. 2, it is simultaneously shown that the measuring device u is disposed on the = month 3, and the shaft adjacent to the striker's hand 21 on.

The geomagnetic sensing unit 12 can define a reference axis through itself and can continuously sense and measure the direction of the magnetic field passing through itself during a measurement period, and then output the message. In the first preferred embodiment, the geomagnetic sensing unit 12 is a 3-axis magnetic sensor capable of detecting three mutually independent independent axial X, less and z axes. A sensor for the orientation of the magnetic field. When the earth magnetic field passing through the four geomagnetic sensing unit 12 changes, the three-axis sensor will output different voltage values, and after calculation, the magnetic field of x, j; and z-axis can be obtained. The intensity and angle are used to determine the direction of the earth's magnetic field passing through the geomagnetic sensing unit 12 at that time. The calculation of the details thereof is generally known to those skilled in the art, and can be easily understood based on the prior art before the application, and will not be described in detail herein. Because the Earth's magnetic field strength is about 0.5 to 0.6 gauss and has a component parallel to the Earth's surface, this component always points in the direction of the Earth's magnetic North Pole 8 200826004 (Magnetic North-pole). The geomagnetic sensing unit 12 is the direction of the earth's magnetic field 4 that is sensed by the direction of the component of the earth's magnetic field parallel to the ground. In the present embodiment, the model of the geomagnetic sensing unit 12 is SEN_S65 (manufactured by PNI Corporation, USA), and has the characteristics of low power consumption, high sensitivity, fast response speed, small size, and high reliability. In the present embodiment, the reference axis eight is set to be parallel to the axial direction of the club 2. Of course, it can also be any spatial linear direction passing through the geomagnetic sensing unit 12, for example, the spatial straight line π shown in FIG. i is saved. The main purpose of the reference axis eight is to record the club 2 at each time period. The direction. The processing unit 13 is electrically connected to the geomagnetism sensing unit 12 for receiving the earth magnetic field measured by the geomagnetic sensing unit 12 in each unit period... in this embodiment, which is a thousandth-second, ms) ^ Signal. The processing unit 13 first finds the angle Θ between the direction of the earth's magnetic field of the force per unit period and the reference axis of the geomagnetic sensing unit 12 at that time. Then, the front and back angles are subtracted, and the change in angle μ is obtained. Divided by the material level period ☆, the instantaneous angular velocity of the club 2 in the heart of each unit is also obtained. After equation (2) ·, c〇=d Θ /dt, the instantaneous velocity factory set on the club 2 can be obtained by using equation (3). Wherein, and the distance between the positions, the rotation center c:::=the center C to the specific position 疋 is located in the striker's arm, the first preferred execution of the arm, the specific position is the club 9 200826004 Xingu # 2疋 baseball bat or 5 ball material, (4) the specific position is far from the end of the bat. In the present embodiment, the processing unit 13 has an arithmetic unit ROM3ι, ..., a read-only memory (ROM) 132 read by the 4-transporter 131, and a random read for accessing the operation H 131. Memory ram i33, one for; = junction = (four) memory H (St (10)) 134, and - a timer providing time function (1 〇 35. The operator 131 can receive the signal of the geomagnetic sensing unit, And outputting the calculation result to the display unit 14. The read-only memory 132 is used to store the necessary transport mode, the structure of the 々μ*, and the logic program, and the random 5 133 is available for the calculation process. In the storage and reading of data, the storage device 134 can be used to store in the storage of the striker at each swing: the data for the practice and research after the supply.日 卩彳 卩彳 | 违 违 违 违 违 违 之 之 之 之 之 之 之 之 之 之 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步 进一步For display, the result calculated by the processing unit U. In the first preferred embodiment, 4 33 is not earlier than the LCD panel 'and It can be set on the housing u = user interface 15, such as a plurality of buttons, to input the value, or other as shown in FIG. 5, the following description is taken as an example of the state of the swing process time period Α. After the introduction of the W, the striker needs to input the value before the swing. The length of the club 2 plus the length of the arm. Usually: the length of the class ^ can be converted by about half of the height, therefore, The measurement device 2 10200826004 can be designed as an input hitter I Gu Shu said 装置 device] automatically converted into a body value of 4 material 2 length, and then by the amount of the tester ' § striker swing, the geomagnetism The sensing unit 12 continuously measures the direction of the earth's magnetic field corresponding to the heart of the unit at that time, and compares the information with the corresponding reference axis at the time, and then finds the relative angle. Plug the plug ^, pick up the difference between the 6 and the thieves 131 to calculate the difference Θ 4 Μ, the city through the formula (7), find the material of the club 2 (four) 'the processing unit 13 ^ # ι ι 131 131 Equation (3)' can obtain the instantaneous swing speed F of the club 2 - the child's early position & 。. And in conjunction with Figures 4 and 5, Figure 6 shows the instantaneous swing speed obtained at the factory and is connected into a curve.

It is to use the difference between the two angles, that is to say, the measurement error of the geomagnetic sensing unit 12 itself will be deducted, and the error of the geomagnetic sensing early 7L 12 can be avoided. In the calculation, the swing speed 求出 obtained by the measuring device can be more accurate. Furthermore, since the measuring device 1 is small in size and easy to carry, it is inexpensive, and it is not necessary to install each of the clubs 2, and is suitable for use in various occasions such as practice and competition. As shown in FIG. 7, the second preferred embodiment of the measuring device for swinging motion of the present invention is substantially the same as the first preferred embodiment, and the similarities are no longer in common, and the differences are not the same. It is further included that an acceleration sensor 16 is electrically connected to the processing unit 13. The acceleration sensor 16 can output the material acceleration to the process: processing. By integrating the heart of the unit time period, the speed value ρ ' of the center of gravity can be obtained and the speed value can be compared with the instantaneous speed K obtained by the geomagnet sensing unit 12, and the dynamic analysis can be improved. Precision. It is added that the combination of the geomagnetic sensing unit 12 and the acceleration sensing unit 6 can also extend the analysis and scoring system of the swing (four). The rhythm refers to the time required to swing the club 2 every time. The rhythm of the top professional level is about 9 seconds to 12 seconds. The unit period of the invention is: 1/1000 second, which should be quite sufficient. It is also possible to find out the proportion of time spent by the lower rod (D_Swing) in the rhythm (ie 12 200826004
