The position data and section time required of the golf ball detected by) are sent to the main apparatus 200 through the first wired transmission / reception means 113.

The first wired transmission / reception means 113, for example, an RS-232 driver, is a widely commercialized device, and the main device 200 stores coordinates and time data of a golf ball stored in the first temporary storage means 112. To pass on.

Next, with reference to Figure 3, it will be described with respect to the main device 200 of the speed, angle and distance measurement system 10 of the entire golf ball according to the present invention. The detailed configuration of the main apparatus 200 includes a second wired transmission / reception means 213, a display means 221, a button portion 222, a second temporary storage means 212, a main memory means 230, a button portion 222. , Sound transmission means 223 and the like.

The second wired transmission / receiving means 213 is generally the same as the sensing device 100, and receives the coordinates and time data of the golf ball measured from the sensing device 100 and stores it in the second temporary storage means 212.

The second control means 210 uses the golf ball coordinates and time data stored in the second temporary memory means 212 with reference to the specific distance characteristic database of the golf club which the main memory means 230 already has. By calculating the speed, angle, flying distance and flight time of the golf ball to the user through the display means 221 again. In addition to this, the average value, maximum value, minimum value, standard deviation, and the like of the flying distance of the golf ball are also displayed through the display means 221.

The measurement value cancel button functions to cancel the data of the golf ball measured this time. The reset button initializes the maximum, minimum, average, and standard deviation of the golf ball in the meantime.

The speed, angle and distance and flight time of the golf ball by the configuration of the most basic state, the golf ball coordinate detection and measurement time of the optical sensor The measuring method of will be described with reference to FIGS. 4 to 8, 15 and 16.

4 is a diagram illustrating a sensing device 100 using two optical sensor boards. The golf ball hit by the user using the golf club sequentially passes through the first optical sensor board 123 and the second optical sensor board 123 '. The first optical sensor board 123 detects the beam covered by the golf ball in the first optical sensor board 123, stores the numbers of the beams, and operates a timer. The vertical coordinates of the golf ball can be obtained by combining the numbers of the detected beams. The second optical sensor board 123 ′ also obtains the vertical coordinates in the same manner, and measures the time at the detection of the second optical sensor board 123 ′, thereby measuring the first optical sensor board 123 and the second optical sensor. Measure the time required between boards 123 '.

Figure 5 shows the state of the beam (Beam) is blocked when the golf ball approaches the optical sensor board. It can be seen that the light 2-6 is blocked by the golf ball and the speed vector of the golf ball passes through the light 4.

6 shows a state when the light of the optical sensor board is blocked due to the approach of the golf ball. Where the golf ball is not blocked, the light from the light sensor (T) is detected by the light sensor (R) without any blocking. However, using the detected portion that the light from the optical sensor (T) is blocked by the golf ball, it is possible to obtain the vertical coordinate h of the golf ball. This applies to both the first and second optical sensor boards 123 and 123 '.

The method of obtaining the speed and angle of the golf ball using the vertical coordinate measurement value of the golf ball obtained from the optical sensor board described above and the time required between the first optical sensor board 123 and the second optical sensor board 123 '. This will be described with reference to FIG. 7. The vertical coordinate of the golf ball detected by the first optical sensor board 123 is h1, and the time measured is t1. The vertical coordinate of the golf ball detected by the second optical sensor board 123 'is h2, and the time is t2. If the distance between the already known first optical sensor board 123 and the second optical sensor board 123 'is y', the launch angle (θ_L) of the golf ball is as shown in the following equation.

Sik

Here, the distance y "actually traveled by the golf ball between the first and second optical sensor boards 123 and 123 'using θ_L obtained from the equation is equal to the equation.

Sik

Therefore, if you find the speed (V_0) of the golf ball by using the equation, equation is equation.

Sik

Now, with reference to Figure 8, it will be described how to find the distance of the golf ball using the speed (V_0) and Launch Angle (θ_L) of the golf ball. The velocity vector of the golf ball is divided into x and y axes as follows.

v_x = V_0 cosθ v_y = V_0 sinθ

Therefore, the distances d_x and d_y moved by time t on the x and y axes, respectively,

d_x = (V_0 cosθ) t Sik

Where g is gravity acceleration and g = 9.8 m / s ^ 2.

If the time until the golf ball lands and lands is T, the y-axis moving distance d_y of the golf ball becomes 0 when the time elapses, so that the following equation is given by the formula below.

Sik

If you summarize this for time T,

Sik

Therefore, the distance of the golf ball during the time dwelling time T is the x-axis moving distance d_x of the golf ball during the same time, so as follows.

Sik

So far, the method of obtaining the speed, angle, distance and flight time of the golf ball has been described, but this is a description of the basic configuration of the speed, angle, and distance measurement system 10 of the golf ball, and the launch angle (θ_L) of the golf ball. In addition, in order to consider Azimuth (θ_A), it is possible to additionally add an optical sensor board or change the method of the optical sensor board. I will explain to measure even the horizontal coordinate of the golf ball.

First, referring to FIG. 9, the following description will apply to the above equations ⑻ when considering Azimuth (θ_A). Where y is a distance between the first and second optical sensor boards 123 and 123 ', and the ball is inclined by Azimuth (θ_A). Where Azimuth (θ_A) is

Sik

And the horizontal distance (y ') the golf ball proceeds as follows.

Sik

By using the horizontal travel distance (y ') of the golf ball obtained from the table, it can be applied to the existing table.

Above, based on the configuration and principle of the golf ball speed and angle measurement system 10 using the optical sensor board (123, 123 ', 123 "), with reference to Figure 15, the golf ball in the following sensing device 100 The process of measuring the coordinates, the required time (S101 ~ S108), the detection device 100 determines whether the golf ball approaching from the first optical sensor board 123, if the approach of the golf ball is detected (detecting device ( Time measurement is started by initializing the timer of 100. If the golf ball approaching from the second optical sensor board 123 'is detected within the preset time limit, the required time and the first and second optical sensor boards ( Coordinates of the golf ball at 123 and 123 'are transmitted using the first wired transmission and reception means 113.

Referring to Figure 16, the process (S201 ~ S207) to receive the coordinates and the required time of the golf ball in the sensing device 100 to the user, the main device 200 and the coordinates of the golf ball from the sensing device 100 and Take the time data and calculate the speed, angle, distance and flight time of the golf ball using the formula ⑴ ~ 상기. At this time, the main device 200 outputs the flight sound of the golf ball through the sound transmission means 223 until the golf ball lands in accordance with the flight time of the golf ball. At the landing time of the golf ball, the main device 200 generates the landing sound of the golf ball through the sound transmitting means 223, and through the display means 221, the speed, angle, distance, and distance of the golf ball up to now. The maximum / minimum value, average value, and standard deviation of the ball's flying distance are displayed to the user.

Now, in addition to the configuration of the most basic state of the golf ball speed, angle and distance measurement system 10 to obtain the horizontal coordinates of the golf ball through the three configurations that can measure the Azimuth (θ_A) through FIGS. 10 to 14 Explain.

10 is a configuration diagram in which the optical sensor board 123 "is added to the vertical direction in the speed and angle measuring system 10 of the golf ball using the optical sensor board. This is a golf ball using the optical sensor board in FIG. Since the basic configuration of the speed and angle measuring system 10 can only measure the vertical coordinates of the golf ball, the horizontal coordinates of the golf ball can also be measured by attaching a third optical sensor board 123 " It was made. The principle is as shown in FIG. The optical sensor board (123, 123 ', 123 ") receives the horizontal and vertical light of the golf ball in the optical sensor and measures the coordinates.

Another method of measuring the horizontal coordinate of the golf ball is to detect the vertical and horizontal coordinates by using the reflected waves of the golf ball in the optical sensor board (123, 123 ', 123 ") of the sensing device 100 as shown in FIG. When the approach of the golf ball is not detected, the light emitted from the optical sensor T is detected by the optical sensor R2, but when the golf ball is placed on the beam, the light hit by the golf ball and reflected by the optical sensor R1 ) Is detected, and the horizontal coordinate is obtained by measuring the distance between the light sensor (T, R1) and the golf ball using the time that the light beam is reflected on the golf ball.

Finally, another method of measuring the horizontal coordinates of the golf ball, there are many other aspects of the golf ball speed and angle measurement system 10 using the optical sensor board, as shown in Figure 13 optical sensor board (123, 123) '123') to the ground. As shown in Fig. 14, when the golf ball does not approach the optical sensor, the optical sensors T and R emit light in the vertical direction. When the golf ball is placed in the emitted light, measure the time it takes for the light sensor (T, R) to receive the light reflected from it, and measure the vertical distance and the horizontal distance of the golf ball in the order of the sensor that received the reflected light. It is.

As described above, the present invention provides the user with the speed, angle, and distance of the golf ball that he hits when practicing the swing, and also because of the easier installation, it is easy to install not only outdoors but also indoors. Know the speed, angle and distance of your golf ball.
