At least two of the plurality of weight sensing units 11 and 13 are respectively disposed on both sides of the pedal 10 to respectively detect the weight of the pedal 10 pressed by the left and right feet of the user. The golf ball sensing unit 15 detects whether the golf ball is present. The golf ball sensing unit 15 may be a sound sensing unit, a light sensing unit, or a weight sensing unit, which is described herein by a weight sensing unit. The plurality of weight sensing units 11 and 13 and the golf ball sensing unit 15 respectively sense a plurality of weights at different positions on the pedal 10 and generate a voltage signal corresponding to the weight; the filtering unit 167 removes the noise of the voltage signal; The digit conversion unit 163 digitizes different voltage signals.

The processing unit 161 also determines whether the golf ball is based on whether the golf ball sensing unit 15 detects the presence of the golf ball. The hitting time, in turn, analyzes the tendency of the position of the center of gravity during the user's stroke.

The memory unit 165 stores a comparison table. As shown in Table 1, the reference value included in the comparison table includes the reference value of the percentage of center of gravity shift in each action phase during the swing process, such as the preparation of the general iron shot, the upper pole, and the lower pole.

The left and right weight percentages change over time.

When the user stands on the golf training device 1 and detects the pressure exerted by different feet on different surfaces of the pedal 10 via the plurality of weight sensing units 11, 13, the processing unit 161 first adds all the weights to obtain the total weight. The processing unit 161 normalizes the plurality of weight sensing units 11, 13 by using the total weight of the individual as a reference value to overcome the difference in weight of different users; then, the processing unit 161 pairs the weights After the difference between the weights sensed by the sensing units 11 and 13, respectively, the percentage of the weight of the left and right feet is obtained.

When the weights detected by the plurality of weight sensing units 11, 13 vary from zero to some, after a small amplitude oscillation, the weight percentages of the left and right feet are the same, that is, the user is aiming the ball, and the processing unit 161 uses the As the initial time of recording T ₀ ; taking the right hand swing as an example, when the weight percentage of the left and right feet reaches the maximum value, for example, when the time is T ₁ , the weight percentage of the right foot and the left foot is 75 to 25, the processing unit 161 The weight percentage of this time T _{1 is taken} as the weight percentage of the upper rod.

When the golf ball sensing unit 15 senses that the golf ball is hit, for example, when the golf ball sensing unit 15 detects a change in the weight value from high to low at time T ₂ , the weight percentage of the left and right feet is 50. 50. The processing unit 161 uses the weight percentage of the time T ₂ as the weight percentage at the time of hitting the ball. When the weight percentage of the left and right feet reaches a minimum value, for example, when the time is T ₃ , the weight percentage of the right foot and the left foot is 20 to 80, and the processing unit 161 takes the percentage of the time T ₃ as the weight percentage at the time of the closing. And end the record.

The processing unit 161 determines whether the user's swing motion is correct by the weight percentage recorded when T ₀ , T ₁ , T _{2 ,} and T ₃ , for example, when T ₀ detects that the user is aiming, the golf ball sensing unit 15 If the presence of the golf ball is not detected, the processing unit 161 determines that the golf ball placement position is incorrect, and the processing unit 161 controls the display unit 181 to display a text or a pattern to remind the user to re-swing the ball, or to control the speaker unit 19 to emit a voice. Remind the user to re-swing the ball.

The processing unit 161 detects when the T ₁ weight percent of a user when compared to the rod relative to the reference value, if the detected than 70 weight percent is greater than 30, then the shift lever position of the center of gravity is too large, otherwise too small. If T ₂ detects that the user's weight percentage when hitting the ball is larger than 50 to 50, it means that the user does not hit the ball when shifting to the center, that is, hitting the ball too early, and vice versa. If the weight percentage of the user hitting the ball when T ₃ is detected is smaller than 20 to 80, it means that the position of the center of gravity of the user is too large when the player is closed, and vice versa. The size of the relative reference value of the look-up table can also be recorded by the golf training apparatus 1 as a percentage by weight of the coach's swing and stored in the memory unit 165.
