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 measuring device for measuring the swing speed of the club, some have developed into a large volume. For example, the "Sports analysis and testing system" patent case No. 5,868,578 in the United States is using several high-speed cameras to capture the wave. 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 in each club head, the cost will be 5 1308216 is not cheap, and because of the installation of these measurements, it is likely to change the original of the club itself. Nature has a bad effect. 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 "seven nu^itodng system for golf clubs" patent No. 5,688,183. It is the acceleration measured by the Acceleration Sensor (to determine the angular velocity of the club to 're-step-by-step to find the speed of the club, which is not the case (1), is self-rotating The distance from the center to the club head, ^ is the distance from the position of the accelerometer to the club head. Η一退(1) However, because the acceleration sensor itself is sensitive, it may be due to a slight impact, even in an unshake condition. In the next case, an erroneous trigger will be generated. The measured acceleration value is an absolute value (Absolute Value), that is to say, 'the obtained speed value F will be included in the error of the acceleration sensor itself (Error)' [Inventive] Therefore, an object of the present invention is to provide a measuring device for swing motion, which can improve the accuracy of the measured value. The measuring device of the rod movement is moving simultaneously with a club. The measuring device comprises a hollow housing, a geomagnetic sensing unit housed in the housing, and a housing in the housing. The output of the geomagnetic sensing single 7L Processing unit, and a display unit exposed outside the housing, the geomagnetic sensing unit can define a reference axis through itself, 1308216 can detect three mutually perpendicular independent axial and 2 axial magnetic field orientations And continuously inductively calculate and calculate the direction of the earth's magnetic field through its own time period. The processing unit calculates the direction of the earth's magnetic field corresponding to the time and the reference axis of the geomagnetic sensing unit in the unit time & The change μ of the angle θ is obtained to find the instantaneous angular velocity of the club, that is, (four) the heart 'receives the heart', and the instantaneous velocity r of the specific position on the club can be obtained, where a is - (4) between the center of rotation and the specific position. The center of rotation is the joint of the arm of the striker. The display unit is used to display the result calculated by the processing unit. The effect of the present invention is to obtain knowledge of the use of the geomagnetic sensor. The calculation of the penetration angle of the club at the angle θ' per unit time is obtained, and the angular velocity ω' of the sphere is determined as the difference between the front and the back angles 0 is a relative value (pure "ν-"). Avoiding the swing speed "involving the error in the measurement of the geomagnetic sensing unit" makes the obtained swing speed ^ value. [Embodiment] The foregoing and other technical contents, features and effects of the present invention are In the following detailed description of the two preferred embodiments with reference to the drawings, the present invention will be presented in a detailed description.

In the first preferred embodiment, the geomagnetic sensing unit 12 is a three-axis geomagnetic sensor (3-axlsMagnetieSe, which is capable of detecting three independent vertical axes and: axial magnetic field orientation). a sensor. When the earth's magnetic field passing through the geomagnetic sensing unit 12 changes, the three-axis sensor outputs different voltage values, and after calculation, it can be found at X, 3; The magnetic field strength and angle of the z-axis is used to determine the direction of the earth's magnetic field passing through the geomagnetic sensing unit 12 at that time. As for the calculation of its details, it is a common knowledge in the technical field, according to the prior art before the application. Can be easily understood, will not be detailed here. Because the Earth's magnetic field strength is about 0.5 ~ 〇.6 gauss, and has a component parallel to the Earth's surface, this component always points to the Earth's magnetic North Pole 1308216 (Magnetic North The direction of the magnetic sensing unit i2 is the earth magnetic field direction of the component of the earth magnetic field parallel to the ground. In the present embodiment, the geomagnetic sensing unit 12 Model is SEN _ S65 (manufactured by PNI, USA), featuring low power consumption, high sensitivity, fast response, small size, high reliability, etc. ^ In this example, the reference axis 4 is set to be parallel to the club.

The processing list first finds the angle between the reference point of the geomagnetic sensing unit 12 and the current ^/deficiency axis A. The receiver's then subtracts the front and rear two corners A and Shi, and finds the change of the angle of the angle. The instantaneous angular velocity of the club 2 in each unit period (four) is still obtained, as shown in the following equation (7). : When the mother soap level is ^de /dt V=R〇) (7) After the 'reuse equation (3), the club can be found:) The instantaneous velocity F is set. Among them, and between the special positions of B % Distance, the center of rotation c is a red turn center C to the specific position. The first preferred embodiment: the arm joint of the striker. When the ball 2 is a baseball bat or a softball bat, the specific position is It is the end of the bat that is far away from the striker. In the present embodiment, the processing unit 13 has an -operator 13 that reads the read-only memory (ROM) 132, which is available for the operation. The random read memory (ram) i33 accessed by the device 131, the register Stor 134 for recording the result, and a timer (ck) 135 for providing the time function 136 The signal output by the geomagnetism sensing unit η is output to the display unit 14. The read-only memory 132 is used to store the necessary n-type and logic programs. The random read memory U3 can be used for storing and reading data in the calculation process. The results obtained by the striker at each swing are 'for the purpose of practicing and researching. The timing H 135 is a k-parameter for the day-specific p-bow and private name required to provide the hai-hai operation 131. Further, the timer 135 can also provide a watch function. The display unit is electrically connected to the _βο 兀13 for displaying the result calculated by the processing of the early element 13. ^ In the first preferred embodiment, the display unit 14 is an LCD panel, a 囟w, a baht board, and a user interface 15 disposed on the housing u, such as a plurality of buttons &输入 Enter and value, or other bedding. As shown in Fig. 5, the description of the town is based on the state of the two front and rear unit periods A in the swing process. If first, the striker needs to input the value before the swing, for the length of the club 2 plus the sum of the length of the hand and the value of the value 疋 to #. Usually the length of the human arm can be about the height of the Aifeng Auntie ^ cattle to change the difference. Therefore, the measuring device! Also 10 1308216 counts the input striker height and the length of the club 2, and then the home 1 is automatically converted to the value.

Furthermore, since the measuring device 1 is small in size, it is easy to carry, and the price is low, and it is not required to be installed every one of the clubs: it is suitable for use in various occasions such as practice and competition. As shown in FIG. 7, the second preferred embodiment of the present invention for measuring the motion of the swing motion is substantially the same as the first preferred embodiment, and the similarities are no longer in common, and are not the same. The point is that it further includes an acceleration sensor μ electrically connected to the processing unit. The acceleration sensing H 16 can output 1 pair of accelerations β to the processing early element 13 for processing. By integrating the unit time force, the speed value r can be obtained, and the speed value can be compared with the instantaneous speed r obtained by the geomagnetic sensing early element 12, and the dynamic analysis can be improved. It is worth mentioning that by the combination of the geomagnetic sensing unit 12 and the acceleration sensor 16, it is also possible to extend the rhythm 〇 (10) analysis and grading system during the swing. Among them, the rhythm refers to the time required for each swing of the club 2, the world, the top level of the professional top is about Q9 seconds ~ 12 seconds. The present invention allows the early beta period to be 1/1 G() () seconds, which should have been quite sufficient. It is also possible to use this, the proportion of time spent in the rhythm of Down Swing (ie 12 1308216)

Rhythm, a world-class professional top player, is about 22%~28%. Therefore, if the value of the world-class professional top player is used as the benchmark, the measurement device i can be developed into a scoring system, and more information can be provided to the striker for consideration. Referring back to FIG. 5, 7', in summary, the measuring device for the swing motion of the present invention uses the geomagnetic sensing unit 12 to know the angle Θ of the club 2 at each unit time, and the calculation at the (four) point. The angular velocity of the club 2 is still determined. Since Μ is a relative value, it can avoid the error in the measurement of the geomagnetic sensing unit η itself, so that the obtained swing=degree f can be more accurate and can be extended. Rod distance. At the same time, it is also possible to calculate the impulse Ρ of the ball head 22 and its force F condition, and obtain more swing information. Moreover, if it is used in combination with the acceleration sensor 16, the accuracy of the dynamic analysis can be further improved, and a rhythm analysis and scoring system can be provided, so that the attacker can enhance the striking level according to the data. The object of the invention is achieved. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention can be limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention: It is still within the scope of the invention patent.
