The setting of the setting step 52 includes at least the following three types:

[1] Set mode 521 yourself. The user can set the ball path to control the serving device 20 to serve the ball.

[2] Random mode 522. The control system 30 controls the teeing position of the ball-feeding device 20 in a random number so that the ball landing point is not regular.

[3] Neural network mode 523. The control system 30 has a type of neural network module that changes the position of the tee according to the position of the center of gravity of the user; it applies a neural network trained to detect the user, and the trained neural network Generated by inputting one of the center of gravity positions obtained by the user under a plurality of different receiving positions, and training to an acceptable range with one serving position information as an output (about a neural network, which is a general The technology of knowing is not detailed here).

In the self-setting mode, the user can use the position of the center of gravity to control the position of the ball. For example, when the position of the center of gravity is located in the first area A1, the ball-feeding device 20 serves the eighth predetermined block B8, and the center of gravity is located at the sixth position. In the area A6, the teeing device net serves the seventh predetermined block B7.

In the random mode, since the control system 30 controls the tee position of the ball-feeding device 20 in a random number, it is independent of the position of the center of gravity, but the control system 30 continues to automatically calculate the position of the center of gravity.

As shown in the sixth figure, when the self-setting mode 521 or the neural network mode 523 is selected, the serving step 54 further includes: an input step 541: taking the position of the center of gravity of the user receiving the ball as an input; an output step 542: outputting the tee position information according to the selected mode, and controlling the serving position of the serving device 20; a changing step: after completing the outputting step 541, repeating the inputting step 541 and the outputting step 542, The position of the center of gravity of the user changes to reach a different serving position.

The center of gravity position is used as an input, and the tee position information is outputted by the control system 30 (the operation of the tee position information is determined by the user to set the data parameter) Controlling the serving position of the ball-feeding device 20; the changing step 543: after completing the outputting step 542, repeating the inputting step 541 and the outputting step 542, which may be different according to the position of the center of gravity of the user 70 Serve position.

As shown in FIG. 7B, in the selection neural network mode 523, the process of the serving step 54 is: the input step 541: using the position of the center of gravity of the user to serve as the input of the neural network module. The output step 542 includes two steps of outputting the tee position information 542A and controlling the teeing position 542B of the serving device; inputting the neural network module with the center of gravity position (the neural network computing unit further includes a database, the data After the library mainly includes the network weighting value and the partial weight value 351), the neural network module performs calculation to output the tee position information, and controls the tee position of the serving device 20; the changing step 543: completing the output step 542 Thereafter, the input step 541 and the output step 542 are repeated to achieve different tee positions as the position of the center of gravity of the user 70 changes.

With regard to such a neural network module, an input layer, a hidden layer and an output layer are used to achieve the calculation. The user's center of gravity is the input layer, the hidden layer is a variable of the user's personally trained neural network, and the output layer (ie, the serving position) is via the input layer and the hidden layer. The result of the calculation.

For example, as shown in FIG. 8A, when the position of the center of gravity of the user falls in the fifth area A5, after the calculation of the neural network module, the ball receiving device 20 is controlled to move a sphere 60 toward the center. The ninth predetermined block B9 is sent out; as shown in FIG. 8B, when the position of the center of gravity of the user moves to the eighth area A8, after the calculation of the neural network module, the ball receiving device is controlled. 20 issues the sphere 60 to the second predetermined block B2.

As shown in the ninth figure, it is a system architecture diagram of the present invention, wherein the receiving end 40 receives the radio wave signal of the transmitting end 10 to achieve distance calculation, that is, a ZigBee wireless network positioning system; The system 30 receives the distance information calculated by each receiving end 40, and transmits the distance information calculated by each receiving end 40 to the control system 30 through a signal transmission interface 32. In terms of setting, the control system 30 is provided with an input unit 33 and a display unit 34 for the user to perform related settings; and in the control of the ball delivery device 20, the control system 30 transmits a control command to the controller 21 of the ball delivery device 20, thereby driving the ball delivery device 20 The ball serving device 20 has an angle adjusting portion 201 and a ball feeding portion 202. The angle adjusting portion 201 has an elevation servo motor 201A and a horizontal angle servo motor 201B for controlling the angle of the serving. The ball feeding portion 202 has a ball box 202A, a ball driving motor 202B, and a ball hole 202C.

As shown in the tenth figure, it is a flowchart of the operation of the present invention. After the self-setting mode 521, the random mode 522, and the neural network-like mode 523 are selected in the setting step 52, the following operational steps are performed. Receiving radio wave signals 71 of three transmitting ends: that is, radio waves signals of three transmitting ends 10 are simultaneously received by three receiving ends 40; determining coordinate positions 72 of three transmitting ends: radio waves by three transmitting ends 10 The signal further determines the distance from the three transmitting ends 10, and learns the coordinates of the three transmitting ends 10; the position of the center of gravity of the positioning of the user station is 73: the position of the center of gravity of the user is located according to the coordinate position of the three transmitting ends 10; Output centroid position command 74: Transfer the center of gravity position to the control system 30; perform an operation 75 according to the set tee mode: cause the control system 30 to perform an operation according to the set tee mode (when the neural network mode 523 is selected, the control The system 30 operates based on the data of the database 35 of the neural network module; the control system transmits a control command to the ball delivery device 76 as a result of the operation: the control The system 30 calculates the starting position of the ball according to the setting, and controls the service of the ball-feeding device 20 with a control command; the ball-sending device performs the service of the ball 77 according to the control command: the ball-feeding device 20 performs the predetermined position according to the control command transmitted by the control system 30. Serve; stop 78: After the serve, you can choose to continue to serve or end; if you choose to continue the serve, the next ball drive signal 79 will be transmitted.

In summary, the advantages and effects of the present invention can be summarized as follows:

[1] Different courses can be changed according to the user's center of gravity. The conventional teeing device has a fixed serve mode that is not new and is relatively easy to be grasped by the user to lose its interest. However, the present invention utilizes a neural network to change the serving ball with the user's 70 center of gravity. Road, the ball path changes and is difficult to master, which can increase its entertainment.
