Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a swing measuring device used for swing practice of a golf club or the like.

[Prior art]

In general, when practicing golf, etc., it is of course important to increase the flight distance of the ball, but it is also important to make the club head speed and flight direction accurate, which are the elements of ball flight distance, and always keep this in mind when practicing. This is something that must be maintained. Therefore, whether practicing swinging or actually hitting a ball, it is important to know the swing state of the golf club, that is, the state in which the club head is catching the ball. Therefore, in Japanese Patent Application No. 57-31898, the present applicant calculates the club head speed by processing various measurement data obtained by detecting the swing state of a golf club.

Golf practice devices have been proposed that are capable of outputting various data such as ball flight distance and face angle at impact to a monitor device.

[Problem that the invention seeks to solve]

On the other hand, the quickest way to improve your golf skills is to learn about changes in your swing status up to the present when practicing, and compare your past swings or ideal swings to check your practice results and future improvements. The next step is to practice.

However, even with the golf practice device proposed above that allows you to obtain various data related to your swing, it is difficult to compare changes in your own swing status up to now and your ideal swing, and it is difficult to compare your practice results and future swings. The problem was that it was not easy to find out what improvements could be made.

The present invention was made to solve such problems,
The object of the present invention is to provide a swing measuring device that allows one to easily know the results of practice to date and points for improvement in the future.

Means for Solving Problem C] The swing measuring device according to the present invention includes a storage means for storing comparison target data such as past data or ideal data regarding the swing of a swing member, and a detection process for the comparison target data. It is provided with arithmetic processing means for generating various swing data based on the measurement data and outputting the data to an output means.

[Effect]

In the present invention, comparison target data such as swing data based on previous measurement data, that is, past data or ideal data based on an ideal swing, is stored in the storage means. The arithmetic processing means performs arithmetic processing on the swing data based on the measurement data obtained from the new swing and the data to be compared, and generates various swing data such as statistical data, average data, comparison data, etc., edits the data, and outputs the data. Output to.

〔Example〕

The present invention will be explained below based on the embodiments shown in FIGS. 1 to 3. FIG. 1 is a block diagram showing the internal configuration of this embodiment. In FIG. 1(a), 1 is a detection means for detecting the swing state of a swing member, and a plurality of magnetic sensors etc. for detecting the passage of a golf club are installed. The sensor group 2 arranged separately is an analog processing section that amplifies and filters each detection signal from the sensor group 1 and converts it into a digital signal. 3 is a digital processing section, 4 is a control section, and the digital processing section 3 generates timing signals and control signals that are easy to process in the control section 4 based on each detection signal converted into a digital signal by the analog processing section 2. These signals are generated and transferred to the control section 4. That is, the time difference, amplitude value, etc. between each detection signal are detected as measurement data, and together with the analog processing section 2, it constitutes a signal processing means 5. On the other hand, the control section 4 includes an arithmetic processing section 6 and an output section 7.
The signal processed by the arithmetic processing section 6 is sent to the output section 7.
Here, the data is converted into display data or printout data, and is outputted to the printer device 10 as a printing section via the display section 8 or the output connector 9. Note that the output unit 1) is output by the output unit 10 or the printer device 10.
is configured. FIG. 6(b) shows the control unit 4 by function. The arithmetic processing unit 6 stores a central processing unit (CPU) 12 as an arithmetic processing means and stored data even when the main power (not shown) is turned off. It consists of a random access memory (RAM) 14 as a storage means equipped with a bank-up battery 13 for holding, and a one-way only memory (ROM) 15 in which unchangeable data such as programs is stored in advance, and the CPU 12, RAMI 4 ．． ROMI 5
and the output section 7 are connected by a signal bus 16. The CPU 12 operates based on a predetermined program stored in the ROM 15, and processes various measurement data from the digital processing section 3 to determine the swing speed and trajectory of the club head, the face angle at the time of impact, the hitting position, etc. Further, swing data such as flight distance and launch direction of the ball, OB judgment, etc. are calculated from the calculated values and stored in the RAM 14. As described above, the RAM 14 stores the swing data up to the previous time as past data, and also stores in advance the ideal data from the ideal swing.
3, it is maintained for a long time.

Next, FIG. 2 shows an external view of the golf practice device according to this embodiment. In the figure, 17 is a mat base on which a mantle 8 made of artificial grass or the like is placed, and the mat base 17 is
The above-mentioned sensor group I and analog processing section 2 are built in. I9 is a main body of the device connected to the mat base 17 by a connecting cable 20, and the main body 19 houses the digital processing section 3 and the control section 4 described above, as well as a display section 8 consisting of a liquid crystal display element and an output. A connector 9 is provided. And the above output connector 9
A printer device 10 serving as a printing section is connected to via a connection cable 21.

Next, the operation of this embodiment will be explained based on the flowchart shown in FIG. First, in step Sl, it is determined whether or not the golf club has been swung based on the presence or absence of a detection signal from the sensor group 1. If the golf club has not been swung, this step Sl is repeated until the golf club is swung away.

Here, when it is swung, the process moves to step S2, various measurement data signal-processed via the analog processing section 2 and digital processing section 3 are read, and the process moves to step S3. In step S3, it is determined whether the various measurement data obtained in step S2 are valid or invalid. If valid, the process moves to step S4, and if invalid, the process returns to step Sl. In step S4, various calculations are performed based on the effect measurement data, and the calculation results, that is, the various swing data of this time described above, are stored in the RAM 14, and the various swing data of this time and the previous swing data stored in the RAM 14 are stored. The various swing data up to now, that is, the past data and the ideal data, are arithmetic-processed, the various swing data up to this time are aggregated, the average and the difference with the ideal data, etc. are calculated, and the process proceeds to step S5.

In step S5, the calculation result in step S4 is edited for display, printout, etc. and sent to the output unit 7, and the process moves to step S6. In step S6, the various swing data edited in step S5 are converted into display and printout data, such as ASCII code, and sent to the printer device 10 via the display section 8 and output connector 9. The sent various swing data can be visually checked on the display unit 8 and can also be obtained in printed form from the printer device 10.
