Figure 6 is a block diagram of a golf swing analysis device according to the present invention. Referring to FIG. 6, when a sensor unit 203 including at least one sensor configured in the main frame 100 detects a movement of a golf club, a detection signal is provided to a control unit 201 configured as a predetermined microcomputer. Based on the detection signal, the control unit 201 controls the LED unit 204 including at least one LED set to correspond one-to-one with the sensor so that the user can visually sense the sensor on which the golf club is detected through the lit LED. By making it possible to determine the movement trajectory of the golf club can be easily identified.

On the other hand, the swing analysis device for golf according to the present invention may determine the expected movement state of the golf ball based on the physical data generated in accordance with the movement of the golf club and provide it visually, this in detail with reference to FIG. Explain.

7 (a) is an embodiment of an operation of the golf swing analysis device according to the present invention, the golf club 300 is excessively over any one of the sensors disposed on the first subframe 102 by the swing operation of the golfer. The sensor generates a detection signal, and the control unit configured in the golf swing analysis device turns on a predetermined LED to correspond to the detection of the sensor to visually indicate the entrance path of the golf club, and the golf club is connected to the golf ball. If any one of the sensors disposed on the second subframe 101 is excessive after the impact, the same process as when passing through the first subframe 102 occurs. Accordingly, the controller detects the sensors of the first subframe 102 and the second subframe 101 in response to the golf club, and based on the horizontal distance and the vertical distance between the sensors, the angle of the golf club 300 is moved. , The physical direction of the running direction, the moving speed, the swing tempo is calculated and the movement of the golf ball 20 moves integrally with the golf club 300 until immediately before leaving the golf swing analysis device, the movement of the golf club 300. Since it is almost identical to the control unit, the control unit generates physical data on the direction and expected distance of the golf ball based on the physical data.

In this case, when the detection signal is generated in the sensor of the first subframe 102, the controller regards only the detection signal of the sensor last measured in the second subframe 101 as a valid signal, thereby causing the golfer to swing back. The detection signal measured in the first subframe 102 may be invalidated to prevent an error during measurement, and the measurement noise generated during post-swing correction may be ignored.

On the other hand, the swing analysis device for golf according to the present invention hits the golf ball as shown in Fig. 7 (a), even when the golf ball is out of the golf swing analysis device to the expected course of the golf ball over time It can be visually shown through the LED of the second subframe 101, which is shown in detail in Figure 7 (b).

Referring to FIG. 7 (b), the driving direction and the expected distance of the golf ball, which are physical data generated by the controller, are divided in time to show an expected course through the LEDs. In more detail, when the golf club passes the sensor of the second subframe 101, the LED corresponding to the sensor is turned on, and at the same time, the estimated flying distance of the generated golf ball is divided by the advancing angle and the running speed of the golf club every time. At this time, the golf swing analysis device and the expected position of the golf ball moving on the horizon may be sequentially counted and turned on from the first LED to the expected distance and the LED located on the horizon.

At this time, the control unit stops the lighting count of the corresponding LED when the final estimated flying distance is reached and provides the golfer with the final position of the golf ball through the last lit LED, and the golfer provides the LED with the expected flying distance of the golf ball and blinking. Use this to identify the location of the golf ball. In addition, when the expected position is out of the measurement range of the second subframe 101, an end LED may blink to indicate an error.

Meanwhile, the golf swing analysis device according to the present invention provides a simple user interface 120 for user's convenience. Referring to FIG. 8, the user interface 120 allows the user to determine the type of golf club. The control unit may include a button for selecting a club, and according to the selected club type, the controller compares a swing speed currently measured based on a look-up table or an expression for an average distance corresponding to a swing speed of a predetermined club type. Can be calculated.

In addition, the user interface 120 may select various modes provided by the control unit so that the physical data generated by the control unit may be displayed on the display with respect to a swing that is currently performed. The user interface 120 By setting the swing analysis for a specific number of times based on the input of the control unit, the control unit may generate the average value of the physical data according to the repetition of the swing or compare the previous swing with the current swing and display it on the display. Not only shows how efficiently the swing is being performed, but also compares the data value generated during the swing of the professional golfer with his own data value, and his swing is slightly behind the angle or speed based on the professional golfer's swing. It's easy to see if it's going off. All.
