[0024] The present invention is further described below in conjunction with the embodiments.

[0025] Example 1

[0026] Figure 1 , Figure 2 , Figure 3 , Figure 4 In the embodiment 1 shown, 4 is the base of the gateball motion simulator measuring device, and a fixed initial position O of the gateball is set on the base 4 as the starting point for pushing the gateball, O2 is the striking position for placing the gateball, and the initial position 0 and the striking position 02 are 7.5 cm apart from a gateball diameter. Figure 1 The OA line marked in is designated as the positive rolling path of the goal ball 7 and is used as the basis for data and calculations. C is the fan-shaped effective rolling area surface of the goal ball. Figure 12a and 3a on both sides of the middle sector-shaped effective rolling area surface C are two photoelectric signal transmitting devices, 2b and 3b are two photoelectric signal receiving devices, 2a and 2b form a pair of photoelectric switches, 3a and 3b form another pair of photoelectric switches, and 2a, 3a and 2b, 3b form a third sensor. 2a, 3a and 2b, 3b are symmetrically and cross-mounted on the base 4 with the OA line as the symmetry axis. Photoelectric linear signal paths y and x are formed between 2a and 2b, and 3a and 3b. The linear signal paths x and y are parallel to the sector-shaped effective rolling area surface C, cross the sector-shaped effective rolling area surface C horizontally, and the height from the sector-shaped effective rolling area surface C is less than the diameter of the goal ball. Figure 3 Oa is a hollow ball holder made of elastic material, which is installed at the initial position and the flash position respectively, and the upper end of the ball holder is substantially flush with the fan-shaped effective rolling area surface C. In the figure, 1 (1a / 1b) and 11 are the first sensor and the second sensor respectively, and 1 (1a / 1b) and 11 are reflective photoelectric switches with the photoelectric signal path z upward, which are installed under the ball holder Oa. Figure 3 The fourth sensor is a grating composed of a group of opposing photoelectric switches. The photoelectric signal paths of each pair of photoelectric switches of the fourth sensor are parallel to each other and are arranged at a certain interval above the fan-shaped effective rolling area, forming a spatial vertical relationship with the OA line. Figure 4 The figure shows the multi-path photoelectric signal paths mm of the fourth sensor which are parallel to each other and perpendicular to the OA line from the OA direction. The transmitting device and the receiving device of each pair of photoelectric switches of the fourth sensor are respectively installed on the two sides 6 of the fan-shaped effective rolling area C; when the goal ball is hit at an elevation angle of β and passes through the fourth sensor, a certain on-off state value of the multi-path photoelectric signal path of the fourth sensor, that is, a certain angle value, is corresponding. 5 in the figure is a baffle erected in front of the rolling path of the goal ball. There is a signal acquisition and processing device connected to 1 (la / 1b), 2a, 2b, 3a, 3b and the fourth sensor.

[0027] When the utility model is used, the goal ball 7 is first placed on the ball holder 0a, and the reflective photoelectric switch 1 (1a / lb) is triggered after detecting the goal ball, and the electronic system starts initialization and waits. When the goal ball is pushed forward and leaves the initial position 0, the reflective photoelectric switch 1 (1a / lb) is triggered, and the signal acquisition and processing device starts timing. In the process of the goal ball continuing to move forward, the signal acquisition and processing device records the moment Tx and Ty when the signal paths x and y are cut off by the goal ball, and records the angle value β corresponding to the on-off state of the multi-path photoelectric signal path of the fourth sensor when the goal ball passes through the fourth sensor. The circuit program calculates the speed of the goal ball movement and the direction angle relative to the OA line based on Tx, Ty, β and the position parameters of 2a, 2b, 3a, and 3b relative to the initial position 0, and after appropriate correction, thereby achieving the purpose of measuring the speed and direction of the goal ball 7 when it is pushed.

[0028] like Figure 5 As shown, E is the intersection of signal paths x and y. When the goal ball 7 moves forward, the signal paths y and x are cut off at points N and M respectively, and the time parameters Ty and Tx mentioned above are obtained. In triangles OEM and OEN, since the side OE and the angles μ and ν are constants, the angle α is the direction angle of the goal ball's trajectory relative to the OA line, and the sides OM and ON are functions of the angle α: 0M=f1(α), ON=f2(α). Assuming the speed of the goal ball is v0, then,

[0029] OM=vO*Tx,ON=vO*Ty

[0030] OM / ON=Tx / Ty

[0031] Tx / ty=f1(a0) / f2(a0), calculate the angle α value, and then calculate v0.

[0032] During implementation, the first sensor and the second sensor can be infrared photoelectric switches or laser photoelectric switches, and the utility model is also equipped with an image processing unit and an image display terminal. The signal acquisition and processing device inputs the gateball motion parameters into the image processing unit, and the display terminal of the image processing unit displays the motion of the gateball on the court.

[0033] Example 2

[0034] like Figure 6 As shown, different from Example 1, two photoelectric signal receiving devices 2b, 3b share one photoelectric emitting device 3a (2a), and signal paths y, x are formed between the photoelectric receiving devices 2b, 3b and the photoelectric emitting device 3a (2a). In the figure, the goal ball 7 moves forward through the signal paths x, y and the signal path of the fourth sensor. According to the calculation method introduced in Example 1, in the triangles OMF and ONG, since the sides OF, OG and the angles μ, ν are constants, the goal ball movement speed v0 and the movement direction angle α relative to the OA line are calculated based on the triangle side angle function relationship.

[0035] Example 3

[0036] like Figure 7 As shown, unlike Example 1, sensor 3 is a mirror reflection type photoelectric switch. A signal path xx is formed between the photoelectric emitting device (2 / 3) a of the mirror reflection type photoelectric switch and the reflective mirror 8, and a signal path yy is formed between the reflective mirror 8 and the photoelectric receiving device (2 / 3) b of the mirror reflection type photoelectric switch. When the goal ball moves forward through the signal paths xx and yy, the signal acquisition and processing device records the moments Tx and Ty when the signal paths xx and yy are cut off by the goal ball. According to the calculation method introduced in Example 2, the goal ball movement speed and the movement direction angle relative to the OA line are calculated.

[0037] Example 4

[0038] like Figure 8 As shown, unlike Example 1, the first sensor is a beam-type photoelectric switch, and its photoelectric emitting device 1a and photoelectric receiving device 1b are separately installed on the upper and lower sides of the initial position 0 of the gate ball, and the signal path z formed between the emitting device 1a and the receiving device 1b is blocked by the gate ball placed at the initial position. As a variation of this embodiment, the first sensor can be a reflective photoelectric switch in which the emitting device 1a and the receiving device 1b are integrated into one body, and is installed on the upper or lower side of the initial position 0 of the gate ball, and the gate ball at the initial position is located on the signal path z of the reflective photoelectric switch. The reflective photoelectric switch should use a photoelectric switch with a linear signal path with strong directionality, such as a mirror reflection photoelectric switch or a reflective laser photoelectric switch, to ensure the accuracy of positioning and data measurement.

[0039] Example 5

[0040] like Fig. 9 As shown, unlike Example 1, 2a / 2b and 3a / 3b are reflective photoelectric switches with two transmitting devices and a receiving device integrated together, which are installed on the same side of the fan-shaped effective rolling area C. The linear signal paths x and y of 2a / 2b and 3a / 3b are reflective photoelectric signal paths. When the ball passes through the signal paths x and y, the switch state of the photoelectric switch will change, and the circuit will record the moment when the switch state of 2a / 2b and 3a / 3b changes, thereby achieving the purpose of measuring the speed and direction of the gate ball when it is pushed. In specific implementation, the reflective photoelectric switch should use a photoelectric switch with a linear signal path with strong directionality, such as a mirror reflective photoelectric switch and a reflective laser photoelectric switch, to ensure the accuracy of positioning and data measurement. 8 in the figure is a reflective mirror used by the reflective photoelectric switch.

[0041] Example 6

[0042] like Fig.10 As shown, the difference from Example 5 is that the reflective photoelectric switches 2a / 2b, 3a / 3b are respectively installed on both sides of the fan-shaped effective rolling area C. In specific implementation, the reflective photoelectric switch should adopt a photoelectric switch with a linear signal path with strong directionality, such as a mirror reflection photoelectric switch and a reflective laser photoelectric switch, to ensure the accuracy of positioning and data measurement.

[0043] In the above six embodiments, the initial position 0 and the fan-shaped effective rolling area surface C are basically on the same horizontal plane, and the fan-shaped effective rolling area surface can be an artificial turf surface. The signal paths x and y are on the same plane and parallel to the horizontal plane where the fan-shaped effective rolling area surface C is located. This setting can improve the measurement accuracy and reduce the difficulty of calculating data correction. In the embodiment, the OA line is an internal reference for data calculation and does not need to be clearly marked on the measuring device.
