DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a sensible game providing system and method, and a sensing apparatus therefor according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram showing an example of a schematic configuration of a sensible game providing system according to the present invention.

Referring to FIG. 1, a sensible game providing system analyzes signals sensed by at least one sensing frame 100 and sensing frames 100 and 102 that sense an object passing therethrough, and calculates physical characteristics such as coordinate and velocity of the object And a signal processor 110 for processing the signal.

Although the present embodiment shows a case where there are two sensing frames 100 and 102, the present invention is not limited thereto and may be implemented by including one or three or more sensing frames.

The sensing frames 100 and 102 generate lattice-shaped lasers 130 using a light emitting element and a light receiving element located in holes 120 formed at predetermined intervals in a rectangular frame. Although this embodiment illustrates a portion of the laser grating 130 for the sake of clarity, the laser grating 130 is not visible to the actual human eye.

It is preferable that the rectangular frame of the sensing frames 100 and 102 be made of a material resistant to external impact and temperature change. As an example, in order to effectively dissipate the heat generated in the sensing device located within the rectangular frame, the rectangular frame may be made of aluminum.

The signal processing apparatus 110 grasps information such as coordinates, speed, and direction of various objects (for example, baseball ball in the case of a baseball game) passing through the sensing frames 100 and 102. The signal processing apparatus 110 can recognize the physical characteristics (velocity, direction, coordinates, etc.) of an object by using one sensing frame 100 or 102 or use information of two or more sensing frames 100 and 102 together Physical properties can be grasped. When two or more sensing frames 100 and 102 are used, the signal processing apparatus 110 can more accurately grasp the speed and direction of the object on the basis of the distances between the sensing frames 100 and 102. The detailed configuration of the signal processing apparatus 110 will be described with reference to FIG.

2 is a diagram showing a part of a frame of a sensing frame according to the present invention.

Referring to FIG. 2, the sensing frame 100 has concave grooves formed in the frame, and holes 120 are formed at regular intervals in the grooves. The laser light emitting element and the laser light receiving element are located in the holes facing each other in the sensing frame.

The distance between the holes where the sensing devices such as the light emitting device or the light receiving device are located can be variously set according to the field to which the present invention is applied. For example, when applied to a baseball game, the interval between the holes can be set to be smaller than the diameter of the baseball hole so that the baseball ball can be detected by at least two sensing devices.

When a sensible game system according to the present invention is applied to an indoor baseball game, since the length and length of the sensing frame are several meters, it is difficult to focus the laser between the light emitting element and the light receiving element. An example of a sensing device for this purpose is shown in Fig.

4 is a cross-sectional view of a sensing device according to the present invention. FIG. 5 is a sectional view of the sensing device of FIG. 1 when the sensing device is mounted in the sensing frame of FIG. Fig. 3 to 5 together.

3 and 4, the sensing device includes a fixed frame 300, a sensor unit 330, and an adjusting screw 350. [

The fixed frame 300 includes a fixing hole 310 having a first curvature and three or more adjustment holes 320. Although the present embodiment shows one fixing hole 310 in the fixing frame 300, the fixing hole 300 is not limited thereto, and the fixing frame 300 may include at least two fixing holes.

The sensor unit 330 includes a laser emitting element 360 or a light receiving element on its upper surface and a protrusion 340 having a second curvature corresponding to the fixing hole 310 of the fixed frame 300 on the lower surface thereof. In this embodiment, the upper surface of the sensor unit 330 is formed as a circular plate, and the protrusion 340 is formed under the circular plate. However, the present invention is not limited thereto, and the shape, thickness, Variable design is possible.

The fixing hole 310 and the protrusion 340 are spherical, and the protrusion 340 is inserted into the fixing hole 310. The first curvature of the fixing hole 310 is equal to or greater than the second curvature of the protrusion 340 so that the protrusion 340 can be stably inserted into the fixing hole 310. More preferably, The same thing is good.

The length of the arc of the protrusion 340 is longer than the length of the arc of the fixing hole. That is, the height of the projection is longer than the depth of the fixing hole. Therefore, a clearance is formed between the upper surface of the sensor unit 330 and the fixed frame 300, and the clearance allows the protrusion 340 to be inclined at 360 degrees in any direction from the fixing hole 310. The focal position of the laser emitted from the light emitting device 360 located on the upper surface of the sensor unit 330 can be adjusted according to the inclination direction or the degree of the protrusion 340. [

The adjusting screw 350 penetrates the upper surface of the sensor unit 330 and is inserted into the adjusting hole 320 existing in the fixing frame 300. At least three adjustment screws 350 and adjustment holes 320 are required to stably fix the sensor unit 330 to the fixed frame 300. But may include four or more adjustment screws and adjustment holes depending on the embodiment. Since the head of the adjusting screw 350 is formed with a groove that can be turned by the driver, the user can turn the adjusting screw 350 to finely adjust the inclination and direction of the sensor 330.

Referring again to FIG. 4, the sensing device includes an electric wire 400 powered from the outside, and the electric wire 400 penetrates a hole formed in the bottom of the fixing hole 310 below the protrusion 340.

Referring to FIG. 5, the sensing device is located inside the sensor frame corresponding to the position of the hole of the sensor frame. It is important to supply a constant current to each light emitting element in order to improve the quality of the laser point. To this end, each of the sensing devices includes an output adjustment unit 500. The output adjusting unit 500 may be implemented using an electric device on a PCB substrate, and the output adjusting units 500 that exist in each sensing device operate independently of each other. The user can adjust the magnitude of the current input to each sensing device through adjustment of the variable resistance of the output adjusting unit 500. [

FIG. 6 is a view showing a configuration of an example of a sensing device including a light receiving element according to the present invention, and FIG. 7 is a diagram showing a cross section when the sensing device of FIG. 6 is mounted in the sensing frame of FIG.

6 and 7, the sensing device including the light receiving element includes a light receiving element 610 fixed to the fixed frame 600 and a lens 620 for better receiving the laser light emitted from the light emitting element do. The sensing device including the light receiving element is positioned opposite to the sensing device including the light emitting element at the one-to-one correspondence with the sensing frame, and receives the laser light emitted from the light emitting element.

In order to prevent misdetection due to various disturbance lights, it is necessary to use a light receiving element which responds to strong light in order to react only to the laser point. Such a light receiving element generally has a slower detection speed than 1 ms It is not suitable for sports games such as baseball. For example, the time taken for the center of a baseball ball moving at 150 km / h to pass through a laser grid formed in the sensor frame is about 1.7 msec at maximum.

The reception sensing unit 700, which is located below the fixed frame 600 of the sensing device and connected to the sensing device by the electric wire 630, measures the intensity of the light detected by the light receiving device having a fast reaction speed, And a cut-off circuit for detecting the laser light when it is detected.

In order to transmit the laser reception signals of hundreds of sensing devices installed in the sensing frame of FIG. 1 to the signal processing device (110 of FIG. 1) in a 1: 1 (parallel) manner, several hundreds of signal lines are required. The present embodiment serializes the signal line between the sensing devices and the signal processing device 110 to reduce the signal line. For example, the signal processing apparatus 110 receives a laser detection signal together with a unique signal capable of distinguishing the sensing devices from the sensing devices, thereby determining which signal received from the one serialized signal line is a signal received from the sensing device .

FIG. 8 is a diagram illustrating an example of a baseball game using a sensible game providing system according to the present invention.

Referring to FIG. 8, a sensible game providing system for a baseball game includes a pitching machine 800, at least one sensing frame 810, 820, and a signal processing device (not shown).

The pitching machine 800 is a mechanism for throwing the ball 830 at various speeds and pitches. For example, for a more interesting game, a signal processing device (not shown) can control the pitch and speed of the pitching machine according to the game situation.

The baseball ball 830 thrown by the pitching machine 800 flies toward the user located in the other magnet past the sensor frames 810 and 820. By the impact of the user, the baseball ball passes again through the sensor frames 810 and 820 in the opposite direction. Of course, there are cases where a user can not hit a baseball. In this case, the baseball ball is detected only once by the sensor frame.

The signal processing device grasps the velocity, coordinates, and direction of the ball when the ball passes the sensor frame. For example, when a baseball passes a laser grid formed on a sensor frame, some laser lines are covered by a baseball, so that the light receiving element becomes a laser-off state in which it can not receive laser light. The signal processing apparatus grasps the physical characteristics of the baseball hole 830 using the positions of the sensing devices in the laser off state, the duration of the laser off state, and the like.

There are a variety of ways to identify the physical characteristics of a baseball ball using two or more sensor frames.

For example, the signal processing apparatus can recognize the coordinates and the velocity of the baseball ball using the respective sensor frames 810 and 820, and determine the interval between the sensor frames and the time taken for the baseball ball to pass between the two frames, Can be grasped.

As another example, since the position where the baseball ball is thrown to the other magnet by the pitching machine does not change much, the signal processing apparatus sets the position where the user hits the baseball ball in the other magnet to the fixed coordinates, The direction? Of the baseball ball can be grasped on the basis of the difference between the coordinates and the fixed coordinates when passing through the baseball ball.

As another example, the signal processing apparatus may determine a first coordinate when the ball dropped by the pitching machine passes through the sensor frame and a second coordinate when the user passes the sensor frame again, It is possible to grasp the direction [theta] using the distance between the magnets, the first coordinate and the second coordinate.

When there are a plurality of sensor frames, it is possible to provide a smooth sensible game even when a sensing device fails. For example, the signal processing apparatus can detect a failure of the sensing apparatus, deactivate the sensing apparatus, and provide a sensible game using only the remaining normal sensing apparatuses.

As another example, a plurality of sensor frames may be divided into an active state and an inactive state, respectively. The signal processing apparatus provides a sensible game using the first sensor frame in the activated state. When a hardware or software failure occurs in the first sensor frame, the signal processing apparatus changes the first sensor frame to the inactive state, By changing the frame to the active state, it is possible to seamlessly provide the sensible service.

9 is a diagram showing a configuration of an embodiment of a signal processing apparatus according to the present invention.

9, the signal processing apparatus 110 includes a state determination unit 900, a coordinate calculation unit 910, a velocity calculation unit 920, a direction determination unit 930, and a simulation unit 940.

The state grasping unit 900 grasps the position and the duration of the off state of at least one or more sensing devices indicating a laser off state generated by an object passing through at least one sensor frame.

The coordinate calculation unit 910 grasps the relative coordinates of an object passing through based on the position of the sensing devices recognized by the state recognition unit 900. For example, in the case where the sensor frame includes 200 grid lines and 100 grid lines, the coordinate calculation unit 910 calculates a coordinate value of the left upper coordinate (0,0) and the right lower coordinate (200,100) It is possible to grasp the relative coordinates of the object passing through. When the interval of the laser grating is narrow, that is, as the interval of the sensing device is narrow, the number of sensing devices that detect the laser off may be large. In this case, the coordinate calculating unit 910 recognizes the horizontal and vertical positions of the central sensing device among the laser-off sensing devices as relative coordinates of the object.

The velocity calculator 920 calculates the velocity of the object based on the laser-off time of the sensing device. For example, in the case of a baseball game, the diameter of the baseball ball is known in advance, so the baseball ball velocity can be calculated by using the laser off time and the diameter of the baseball ball.

As another example, when two sensor frames are used, the speed calculating unit 920 calculates the distance between the first sensor frame and the second sensor frame and the time difference between the first sensor frame and the second sensor frame The speed of the object can be calculated.

The direction determination unit 930 grasps the direction [theta] based on the coordinate difference when the object passes through the two sensor frames.

As another example, the direction determination unit 930 can grasp the direction by using preset reference coordinates, coordinates when the object passes through the sensor frame, predetermined distance between the sensor frame and the user, and the like. In the case of the baseball game shown in FIG. 8, since the position of the ball thrown by the pitching machine is almost constant, one side of the strike zone of the batting table is set as the reference coordinate, and the distance between the sensor frame and the batter, The direction? Can be grasped by using the coordinates of?

As another example, in the case of a baseball game as shown in FIG. 8, the direction determination unit 930 may include a first coordinate when the ball thrown by the pitching machine passes through the sensor frame, and a second coordinate when the ball passes the sensor frame The second coordinate of the sensor frame, and the predetermined distance between the sensor frame and the user.

The simulation unit 940 images the simulation results according to the physical characteristics (coordinates, speed, direction, etc.) of the object using the implemented simulation program and displays them on the screen. For example, in the case of a baseball game, the simulation unit 940 simulates a baseball game image based on the coordinates, speed, and direction of the baseball when the user hits the ball thrown by the actual pitching machine, Display.
