The invention relates to a detectable golf ball, in particular to a wireless signal by contact force or external emission after hitting the ball, so that the antenna, the accelerometer, the magnetometer and the gyroscope are activated, and are turned off within a certain time. A detectable golf ball that combines path tracking, power saving, and power generation by generating power through the rotation of the sphere.

In general, the golf course after the golf ball hits the landing track and the drop point. In the case of the golf driving range, it can provide lighting facilities for the user to observe the ball in the bad state of the sky, evening or night. It is white color light, and the white color of the general golf ball can be said to be the same color color. When the golf ball is hit, it flies out at a very high speed, which makes it difficult to capture the flight curve of the ball after the ball is hit. Height, distance, direction and drop point, and even if the line is in a good daylight, the color of the sphere is easy to mix with the white clouds, green grass or sand of the environment, and there are also situations where the golf course cannot be found and the point of landing is not found.

According to a particular embodiment of the invention, the antenna 1127 can be a Bluetooth module and is adapted to the Bluetooth 4.1 specification by the Bluetooth Special Interest Group (SIG) and can cause the antenna 1127 to enter low power consumption when not in use. mode. In the following, a detailed description will be given of the operation mode of the circuit structure. Here, the timing unit 1127 may be a timer that is commonly used in the field of electronic circuits, and thus detailed description thereof will be omitted.

The mode of operation of the detectable golf ball of the present invention will now be described with reference to Figs. 5 to 8. 5 to 8 are respectively a flow chart of the working mode of the detectable golf ball according to the present invention and first to third schematic views of the working mode of the detectable golf ball. According to a specific embodiment of the detectable golf ball of the present invention, the antenna of the detectable golf ball is a Bluetooth module, and the detectable golf work mode comprises the following steps: First, the remote start detectable The golf ball, the Bluetooth module, the gyroscope, and the accelerometer are turned on (step S501). At this time, as shown in FIG. 6, in the strike preparation mode 6, the detectable golf ball is The ball 605 is placed above the tee 604, and the user 601 first performs Bluetooth communication pairing with the detectable golf ball 605 by using the external transmitter 603, and then turns on the power of the detectable golf ball 605. In other examples, the ball seat 604 can be a ball ejection device. When the detectable golf ball 605 passes over the tee, the pitch management can use the remote control to turn on the power of the detectable golf ball 605.

Then, after the power of the detectable golf ball 605 is turned on, the timing unit starts timing, generating a first sensing time (step S502), and the timing unit returns a first timing signal to the control unit, and triggers the control unit to transmit the first startup. The signal to the accelerometer begins to sense the movement of the detectable golf ball, and the accelerometer emits a first sensing signal. At the same time, the control unit also transmits a second activation signal to the gyroscope, starts sensing the angular velocity of the detectable golf ball 605, and sends a second sensing signal, and the control unit also transmits a third activation signal to the magnetometer, and the feeling is started. The geomagnetic orientation of the detectable golf ball is measured to generate and emit a third sensing signal. The signal processing unit receives the first sensing signal, the second sensing signal, and the third sensing signal, and converts the motion signal back to the processor of the control unit.

Furthermore, the control unit determines whether the gyro and the accelerometer change (step S503), where the sensor and the accelerometer determine whether the change is based on a fault tolerance value to offset the measurement error or the user 601 uses the ball. At 602, it is accidentally touched by the face 606. If the gyro, the accelerometer, and the magnetometer do not change, the control unit determines whether the first sensing time exceeds X minutes according to the first timing signal (step S504), and if not, the timing unit continues to time (step S505). And returns to step S503. Here, the X minute setting is to enter the power saving mode in order to save power if the user 601 does not perform the hit after the detectable golf ball 605 is turned on or passed through the ball shooting device. Therefore, if it is determined in step S504 that the first sensing time exceeds X minutes, the power saving mode is entered, that is, the Bluetooth module enters the standby mode, and the gyroscope and the accelerometer are turned off (step S506). Please refer to the figure in Figure 8 here. The segments S81 to S83 do not hit after a period of time T2 after the ball is taken out, and if T2>X, the power saving mode is entered.

After step S506, the detectable golf ball 605 is in the power saving mode until the user 601 turns on the power by the external transmitter 603. When the user 601 turns on the power of the detectable golf ball 605 by the external transmitter 603, the Bluetooth module transmits the stored motion signal to the external transmitter 603 (step S510). Here, if the gyroscope and the accelerometer are not changed, the stored motion signal can be a null value.

If it is determined in step S503 that the gyro, the accelerometer, and the magnetometer have changed, the signal processing unit converts the first sensing signal, the second sensing signal, and the third sensing signal into motion signals, and stores them in the storage. At the same time, the control unit triggers the timing unit to start timing, and generates a second sensing time (step S507). Here, the timing unit provides a second timing signal associated with the second sensing time to the control unit. Next, the control unit determines whether the second sensing time is greater than Y minutes (step S508). Here, the Y minute setting is to enter the power saving mode after a certain period of time after the gyroscope and the accelerometer start to change. According to a preferred embodiment of the invention, Y minutes is less than X minutes, but is not limited thereto.

If the second sensing time is less than Y minutes in step S507, the timing unit continues counting and step S508 is repeated. If the second sensing time is judged by the control unit to be greater than or equal to Y minutes in step S507, the power saving mode is entered, that is, the Bluetooth module enters the standby mode, and the gyroscope and the accelerometer are turned off (step S506). After step S506, the detectable golf ball 605 is in the power saving mode until the user 601 turns on the power by the external transmitter 603. When the user 601 turns on the power of the detectable golf ball 605 by the external transmitter 603, the Bluetooth module transmits the stored motion signal to the external transmitter 603 (step S510).

Please refer to the stages S71 to S76 of Figure 7. That is, when the detectable golf ball 605 is hit by the face at stage S73, the timing unit starts timing, since the detectable golf ball 605 has undergone movement, flight, rotation, and landing between stages S74 to S75. The accelerometer, the gyroscope, and the magnetometer generate changes, and generate the first sensing signal, the second sensing signal, and the third sensing signal, respectively. The signal processing unit converts the first sensing signal, the second sensing signal and the third sensing signal into motion signals and stores them in the storage device. The motion signal includes a change in height and position of the detectable golf ball 605, and can be transmitted to the flight path for subsequent transmission of the motion signal to the remote transmitter 603. Preferably, according to a particular embodiment of the present invention, the external transmitter 603 can be a notebook computer including a communicator, a mobile phone, a portable game device, a portable multimedia player, a tablet computer, a global positioning system ( Global Positioning System, GPS) Receiver, Personal Digital Assistant (PDA) or other device. The map information or the positioning information may be pre-stored in the external transmitter 603, and the user 601 ends the complete golf game. For example, after 18 holes, the external transmitter 603 can perform the point and path of each shot. Draw to achieve an accurate record, and the user can adjust the direction, strength or skill of the shot according to the record.
