The ball sensing gate BSG is made of a pipe material, such as the ribs 12, and is installed in the shape of a rectangle in the rear part of the collar 12. A plurality of light emitting devices (light emitting diodes, infrared light emitting diodes, etc.) arrays are arranged at regular intervals on the upper side and the left side of the ball sensing gate BSG having a rectangular frame shape, and the lower and right sides of the ball sensing gate BSG An array of light receiving elements (e.g., infrared photodiodes or phototransistors) is installed at regular intervals.

The ball sensing gate BSG senses which part (area) of the goalpath 12 has passed when the practice ball passes through the goalpost 12, which will be more clearly understood from the following description. In addition, a speed gun (SG) for measuring the speed of the exercise ball flying toward the goal post (12) is provided behind the ball sensing gate (BSG).

Although the soccer practice apparatus 1 according to the embodiment of the present invention has an example of soccer that a plurality of people can enjoy together, it can be applied as it is in a mini-soccer game of 5 players performed in the room such as a futsal . For example, the soccer practice and the futsal practice can be alternately used, and the position of the goal post 12 installed on the ball 10 can be distinguished according to the game of soccer or futsal. For example, it is conceivable to provide a wheel or the like that can be moved on the lower surface of the goal post 12. In other words, a soccer practice device (1) is installed in the futsal field which can be easily configured indoors so that the soccer field can be easily used as a soccer field for individual or lifetime soccer practice, It is preferable to allow the movable member 12 to move freely.

The ball 10 shown in Fig. 1 is formed to be inclined downwardly by 1 to 5 degrees from the half line HL to the goal line on both sides as shown in Fig. A transfer furrow 14 sloping downward from the one corner to the other corner is formed on the side of the goal line, more specifically, on the rear side of the goalpost 12 so that the practice ball, which has fallen to the bottom surface of the ball 10, The training ball inflow into the conveying valley 14 is guided to the gate G of the ball recliner 200 installed on the corner side along the inclined surface of the conveying valley 14, Lt; / RTI >

The operation of the calliper 200 will be described first with reference to FIGS. 3 and 4. FIG. The conveying valley 14 formed at the rear of the touch line of the ball 10 is inclined downward from one corner to the other corner. Therefore, the practice ball falling from the half line HL to the ball 10 tilted to both sides is rolled in the direction of the goal line from the half line HL, and eventually is collected by the conveying valley 14. The training ball collected by the conveying trough 14 is rolled to the lower end side of the cylindrical collecting pipe or the counterweight handler 200. The training ball introduced into the lower side of the counterweight handler 200 is guided to the lower gate G).

As shown in FIG. 4, when the recovering motor 206 installed on the upper portion of the work machine 200 is rotated, the rotating shaft 208 connected thereto is rotated. At this time, a helical screw 210 having a pitch (for example, 220 mm) that is equal to or about 1 cm in diameter of the drill hole is formed on the outer circumferential surface of the rotating shaft 208 in a spiral shape. At this time, the distance r1 between the rotating shaft 208 and the inner surface of the ball mill 200 is formed to be about 1 mm to 3 mm smaller than the diameter r2 of the training ball. Therefore, when the rotary shaft 208 is rotated, the training ball introduced into the gate G at the lower end of the thread take-up machine 200 is conveyed upward along the screw conveyor 212 composed of the rotary shaft 208 and the spiral screw 210 do. At this time, since the distance r2 between the rotating shaft 208 and the inner surface of the worker 200 is smaller than the diameter r1 of the training ball, the training ball is slightly distorted so that the feeding to the top is smooth.

A diaphragm 214 vibrating in the longitudinal direction by rotation of the vibration motor 216 is buried in the conveying valley 14 at the front portion of the gate G of the reclaiming machine 200. The vibrating motor 216 is rotated simultaneously with the collecting motor 206 during the recirculating operation to smoothly bring the collecting ball collected at the end of the downwardly inclined conveying trough 14 toward the gate G of the copier 200 .

The training ball transferred to the upper portion of the screw conveyer 212 of the ball recycling machine 200 is discharged to the ball discharge pipe 202 by the rotation of the helical screw 210. The training ball discharged through the ball discharge pipe 202 is inserted into the upper opening of the ballast container 104 of the practice ballistic shooting apparatus 100 installed adjacent thereto as shown in Figs. 1 and 3.

In the embodiment described above, the circulator 200 includes a cylindrical collecting tube 204 and a rotary shaft 208 of the helical screw 210. The cylindrical shaft 208 is disposed along the inner wall of the cylindrical collecting tube 204, The screw conveying device having the equivalent configuration can be applied.

For example, two poles that are vertically erected on both sides of a distance of about 1 mm to 2 mm from the diameter (r2) of the training ball in the direction of the gate into which the training ball is drawn from the rotation axis 208 of the helical screw 210, May be considered. When the exercise ball is inflated with the gate of the ball-and-pinion hand constructed as described above, the ball is positioned between the rotary shaft 208 and the two pawls. When the helical screw is rotated, the ball runs along the rotation axis and the two pawls And is then inserted into the upper opening of the airborne vessel 104 of the practice airborne apparatus 100 by being moved in the vertical direction.

The practicing air launching apparatus 100 according to the present invention is configured as shown in Figs. 5 to 9.

5, the practicing air launching apparatus 100 has a space of a predetermined size inside the body 102, and one side, preferably the front side, of the body 102 is provided with an open structure, In the space portion, a practice ball launcher 105 for launching the practice ball is located. At this time, a plurality of components for operating the practice ball launcher 105 are installed in the body 100 so that the practice ball launcher 105 is rotated left and right and up and down, Bars, these internal components and their operating relationship will be described later. In the present invention, a practicing soccer ball actually used is used as the practice ball. In addition, a camera 1 (CAM1) and a camera 2 (CAM2) are installed on the front and side surfaces of the practice launcher 100, respectively. Each of the cameras CAM1 and CAM2 captures a subject in the ballpark 10 and acquires image information corresponding thereto.

The air-conditioner container 104 may be formed in a rectangular tube shape having open top and bottom, and may have a mesh structure to easily identify the amount of the loaded practice ball with the naked eye.

An inlet 107 having a predetermined size is formed on the upper surface of the body 102 to allow the training ball supplied from the airborne vessel 104 to flow into the body 102. The upper surface of the body 102 is provided with a downward inclined surface at a predetermined angle toward the inlet 107 to facilitate introduction of the training ball. At this time, the body 102 and the air-con- tainer 104 coupled to the upper part of the body 102 may be combined by various methods. For example, the body 102 can be joined by welding. A fitting groove is formed at the edge of the upper surface of the body 102, and a fitting protrusion is formed on the lower edge side of the water container 104 so that the fitting protrusion is inserted into the fitting groove And the air conditioner container 104 is seated on the upper portion of the body 102 while being fitted to each other.

Although not shown in the drawings, an operation switch, a display device for displaying an operation, and a key button for setting an operation mode may be provided outside the body 102, for example, a touch screen.

In the present invention, the practicing air launcher 105 installed in the space portion of the body 102 receives the practice ball from the air-con- tainer 104 coupled to the upper portion of the body 100 and emits it. A connecting tube (corrugated tube) 116 of a predetermined diameter extending from the lower portion of the inlet 107 formed in the inclined surface 103 of the body 100 is inserted for transferring the training ball. The connection pipe 116 is connected to the inflow hole 115 opened at the upper portion of the front portion of the hollow body 114 constituting the practice ball launcher 105.

The training ball introduced into the inflow hole 115 of the hollow body 114 is seated at the launching point as shown in FIG. At this time, the hollow body 114 is formed with an internally rounded protrusion 114a at the end thereof, so that the training ball introduced into the inflow hole 115 flows out of the hollow body 114 as a projectile without a blow The phenomenon does not occur. In addition, a sensor provided to the controller (MPU) configured as shown in Fig. 10 is provided at the end of the hollow body 114 to discriminate the presence or absence of the exercise ball. As such a sensor, various sensors such as a photo sensor can be used.

The hollow body 114 is coupled to an upper portion of a shaft joint launching platform 112 provided at a lower portion of the hollow body 114. The shaft joint launching rod 114 is rotatably coupled to a rotation bracket 110 provided at a lower portion thereof, . More specifically, a rack gear 118 is integrally provided on one side of the shaft joint launcher 112 and a drive gear 119 is provided at one end of the rack gear 118 and the shaft joint launcher 112 And the hollow body 114 can be rotated up and down by the inclined motor 117 connected to the driving gear 119 by being provided in a mutually meshed state. The rotating bracket 110 is screwed to a rotating plate 128 coupled to a rotating shaft of a rotating motor 120 provided at a lower portion of the rotating bracket 110 so that the rotating bracket 110 can rotate left and right by driving the rotating motor 120.

As described above, the practice ball launcher 105 of the practice ball shooting device 100 of the present invention has the practice of being positioned at the end portion of the hollow body 114 by the left-right rotation of the rotation bracket 110 and the up- The ball can be fired in the upward, downward, leftward and rightward directions.

The training ball introduced into the hollow body 114 is fired in all directions by the operation of the cylinder 130 coupled to the rear end of the hollow body 114. The piston 132 of the cylinder 130 is inserted into the hollow body 112 as shown in FIG. 9, and the striking plate 134 is coupled to the end of the piston 132. At this time, the cylinder 132 may use a hydraulic or pneumatic cylinder, but it is preferable to use a hydraulic cylinder to fire the practice ball farther.

The hydraulic cylinder 132 has a hydraulic oil inlet and a hydraulic oil outlet. The hydraulic oil inlet is connected to the outlet of the nitrogen tank 144 via a hydraulic drain solenoid valve 150, and the hydraulic oil outlet is connected to a hydraulic return solenoid valve 146 to the hydraulic tank 140. A hydraulic pump 142 is connected between the hydraulic tank 140 and the nitrogen tank 144. A hydraulic pressure supply solenoid valve 148 is connected between the hydraulic pump 142 and the nitrogen tank 144 . At this time, the nitrogen tank 144 has a nitrogen tube filled with nitrogen therein and a pressure gauge for checking the nitrogen pressure of the nitrogen tube. When the hydraulic pressure is supplied to the nitrogen tank 114 having such a configuration, pressure is applied to the nitrogen tube in proportion to the amount of oil supplied, thereby increasing the internal pressure of the nitrogen tube. Increasing information of the internal pressure is provided to the controller (MPU).

The operation of the hydraulic circuit thus configured will be briefly described below. In order to project the piston 132 of the cylinder 30 in all directions, the controller drives the hydraulic pump 142 in a state in which the supply solenoid valve 148 is opened, and the hydraulic pressure in the hydraulic tank 140 is supplied to the nitrogen tank 144 ). When the amount of hydraulic pressure supplied into the nitrogen tank 144 by continuous pumping is increased, pressure is applied to the nitrogen tube installed therein and this pressure increase information is provided to the controller. When the pressure sensing information of the nitrogen tube has a predetermined pressure value, the supply of the hydraulic pump 142 is stopped and the supply solenoid valve 148 is closed. Therefore, it can be understood that the nitrogen tank 148 is filled with hydraulic pressure at a high pressure.

When the launch command is input from the outside (touch screen) to the controller, or when the program reaches a preset launch cycle, the controller opens the discharge solenoid valve 150 only for a certain period of time. When the discharge solenoid valve 150 is opened by the above operation, the hydraulic pressure filled in the nitrogen tank 144 at a high pressure is supplied to the hydraulic oil inlet of the cylinder 130, so that the piston 130 in the cylinder 130 moves forward And the striking plate 134 attached to the end of the striking plate 134 hits the training ball placed at the end of the hollow body 114 and fires in all directions.

When the controller that opens and closes the discharge solenoid valve 150 for a predetermined time opens the recovery and supply slave node valves 146 and 148 and drives the hydraulic pump 142, the hydraulic pressure filled in the cylinder 130 is discharged to the hydraulic tank 140 so that the piston 132 enters the inside of the cylinder.

The controller controls the rotation of the rotation motor 120 coupled to the lower portion of the rotation bracket 110 and the rotation of the inclined motor 117 coupled to the side as well as the operation of the hydraulic circuit described above, Or vertically.

10 is a block diagram of a launch controller of a public artiller according to an embodiment of the present invention, which is provided in the internal space of the body 102 of the practice launcher 100. As shown in FIG. Referring to FIG. 10, the launch controller includes cameras 1 and 2 (CAM1 and CAM2) for illuminating the ball 10 on at least one of four sides of the body 102. As shown in FIG. The two cameras CAM1 and CAM2 are respectively installed to photograph the front side and the center line side of the practice ball shooting device 100 in which the ball is fired. The touch screen TS is provided on one side of the body 102. As described above, the operation switch, the display device for displaying the operation, and the key button for setting the operation mode are provided on the touch screen have.

(CAM1, CAM2) provided from the touch screen (TS) and information of the user's selection action (manual, automatic, camera mode, direction setting mode, penalty kick mode, heading shot mode, Is input to the controller (MPU). The controller (MPU) controls all operations of the practice launcher 100, and is largely divided into a manual mode, an automatic mode, and a camera mode.

In the manual mode, the controller MPU drives the rotation motor 120 and the tilt motor 117 by inputting the direction setting keys (vertical and horizontal) from the touch screen, And actuates the cylinder 130 of the hydraulic apparatus through the solenoid valve driving unit (SOD) by a fire command from the touch screen to fire the practice ball. In the automatic mode, the controller MPU drives the rotation motor 120 and the tilting motor 117 by inputting direction setting keys (vertical and horizontal) from the touch screen, And actuates the cylinder 130 of the hydraulic apparatus through the solenoid valve drive unit SOD every set time period (for example, every 5 seconds) to fire the practice ball. In the case of the camera mode, the controller MPU controls the rotation motor 120 and the tilting motor 117 so that the practice ball launcher 105 is directed in the direction of the practitioner of the ballparks photographed by the cameras 1 and 2 (CAM1, CAM2) After the control, if the practitioner moves with a preset movement (for example, when the practitioner lifts his arm up), the cylinder 130 of the hydraulic device is operated through the solenoid valve drive (SOD) And controls the operation of the practice ball shooting device 100 to fire the ball.

FIG. 11 is a flowchart of an operation of the practice launcher according to the embodiment of the present invention, which is for explaining the operation in the manual mode and the automatic mode.

First, the operation of the soccer practice apparatus 1 shown in Figs. 1 to 9 described above with reference to Figs. 10 and 11 will be described.

As described above, the soccer practice apparatus 1 of the present invention is provided with a touch screen TS on the outside of the body 102. The touch screen TS (TS is attached to a controller (MPU) built in the body 102 The controller MPU controls the operation of each actuating element provided in the body 102 by the data input through the touch screen TS, Control of the operation of the motor 117, the rotary motor 120, the hydraulic pump 142, and the various solenoid valves 146, 148, and 150 is started.

The practicing vehicle launching apparatus 100 can be operated in a manual setting mode and a motion detection mode under the control of the controller (MPU). The manual setting mode is a mode in which a user uses a touch screen (TS) installed in the body 102 to set the exercise mode (penalty kick, corner kick set play, ground ball shot, volley ball, (Eg, a ball is fired every 15 seconds) and then fire the practice ball into the ballpark 10 whenever the firing button is depressed, or one or more of a groundball corner kick, a volley corner kick, and a heading corner kick, (The tilting and rotating motors 117 and 120) of the hollow body 114 according to the exercise mode automatically selected when the user presses the launch button, and the exercising ball is continuously fired at a preset cycle. At this time, Although the example in the touch screen TC has been described, it may be provided in a remote control carried by a soccer practitioner using a conventional remote control device.

Manual setting mode

When the practice ball launching apparatus 100 is operated, the MPU checks the pressure in the nitrogen tank 144 in step S1 so that the piston 132 of the cylinder 130 can be projected (ejected) at a preset speed Search for pressure. If the pressure of the nitrogen tube in the nitrogen tank 140 does not reach the predetermined pressure, the controller opens the recovery and supply solenoid valves 146 and 148 through the solenoid valve driving unit SOD in step S6, 142). Therefore, the hydraulic pressure in the cylinder 130 is recovered to the hydraulic tank 140 and then supplied to the nitrogen tank 144. [ When the hydraulic pressure is continuously supplied to the nitrogen tank 144, the pressure applied to the nitrogen tube installed therein increases to the set pressure.

If it is determined in S2 that the pressure of the nitrogen tank is the set pressure, the controller MPU closes the recovery and discharge solenoid valves 146, 148 and 150 through the solenoid valve driver (SOD) The search button of the touch screen or the remote controller is pressed. If it is determined in step S4 that the fire button is pressed, the controller MPU opens the discharge solenoid valve 148 for a predetermined time t in step S5. At this time, the hydraulic pressure filled with the high pressure in the nitrogen tank 144 is supplied to the inlet of the cylinder 130 through the discharge solenoid valve 148 at a high speed due to the expansion of the compressed nitrogen tube.

Therefore, the cylinder 130 protrudes in the forward direction the piston 132 positioned therein by the hydraulic pressure flowing into the cylinder 130 at a very high pressure, and the impact plate, which is coupled to the end of the piston 132 by the forward protrusion of the piston 132, (134) strikes the practice ball placed at the end of the hollow body (114) and fires in all directions. At this time, the launch angle of the trainer 105 placed in the space of the body 102 of the trainer 100 is controlled by the control of the tilt motor 117 and the rotary motor 120 .

In step S6, the controller MPU opens the recovery and supply solenoid valves 146 and 148 through a solenoid valve driver (SOD) in step S6. Then, in step S7, the MPU drives the hydraulic pump 142 to operate the nitrogen tank 142 are filled with hydraulic pressure.

If the launch button displayed on the touch screen (TS) is not selected in step S4, the controller MPU controls the horizontal, vertical, and launching angles of the practice ball launcher 105 (voluntary) according to the mode set in step S8 After the intervention is controlled, the above-described S5 procedure is performed. In the step S8, the mode is set to the automatic firing mode and the camera mode.

If the setting mode is the automatic firing mode in step S8, the controller MPU drives the rotation motor 120 and the tilting motor 117 by inputting the direction setting keys (vertical and horizontal) from the touch screen, Sets the launch direction of the air launcher 105, and activates the cylinder 130 of the hydraulic device through the solenoid valve driving unit (SOD) every predetermined time period to fire the practice ball. If it is determined in step S8 that the setting mode is the camera mode, the controller MPU controls the operation of the practice launcher 100 in the procedure of FIG. 12, and does not perform any operation in the case of the stop mode in step S8 .

Referring to FIG. 12, in step S104, the controller MPU detects whether the current mode is the camera operation mode. If the result of the search is not the camera operation mode, the process jumps to step S17 and fires the practice ball according to the manual mode operation as described above.

If it is determined in the step S12 that the camera operation mode is selected, the controller MPU receives the image signals photographed in the cameras 1 and 2 (CAM1 and CMA2) installed on the side of the body 102 in step S11, The motion of the subject is detected. The controller MPU detects the position of the practitioner in the ball 12 by the detected subject and then controls the inclination motors 117 and the horizontal motor 120 in step S13 to adjust the vertical angle and the horizontal angle To set the launch angle of the practice ball launcher (105).

In step S14, the controller MPU analyzes the image signal transmitted from the cameras 1 and 2 (CAM1 and CAM2) to analyze the movement of the subject. In step S15, the controller MPU detects whether the motion of the subject is a mirror-set motion. For example, a practitioner in the ballpark 12 searches for a state in which the arm is raised high. This search can be easily performed by comparing the frame image of 1 second before and the image of the current frame.

If it is determined in step S15 that the subject motion of the video signal received through the cameras 1 and 2 (CAM1, CAM2) is a preset motion, the MPU controls the solenoid valve driver (SOD) Similarly, the striking plate 134 provided at the front portion of the piston 132 of the cylinder 130 strikes the training ball so that the training ball is fired toward the target.

The player will be directed to a portion of the ball 10 according to the mode of operation launched from the practice ball launcher 105 and will fly to the touch line or line of the ball to meet the foot of the practitioner, . As described above, the bottom surface of the ball 10 is inclined downward from the half line HL in the direction of the goal line. The balls falling on the bottom surface are automatically moved along the conveying trough 114 formed on the goal line side, And are collected at the gate (G) portion.

The training ball collected at the gate (G) portion of the recall handler 200 is transferred to the upper portion and supplied to the ballast container 104 of the practice ball shooting device 100 as described above.

13, the ball sensing gate BSG coupled to the rear of the frame 12 includes the light emitting device arrays XL1 to XL4 and YL1 to YL10 on the left side and the upper side of the ball sensing gate BSG, And the light receiving element arrays XP1 to XP4, YP1 to YP10 are provided on the right and bottom sides of the ball sensing gate BSG. At this time, the light emitting device arrays XL1 to XL4 and the light receiving device arrays XP1 to XP4 provided on the left and right sides of the ball sensing gate BSG are divided into four equal parts (2440 mm) And the light receiving element arrays XP1 to XP4 and YP1 to YP10 provided on the upper and lower sides of the ball sensing gate BSG are arranged at intervals of 610 mm, (7320 mm) are equally divided into ten equal intervals of 732 mm.

At least three light emitting elements are provided at equal intervals in each of the light emitting element arrays XL1 to XL4 and YL1 to YL10 and corresponding to the light emitting element arrays XL1 to XL4 and YL1 to YL10 At least three light receivers are provided in the interior of each of the light-receiving element arrays (XP1 to XP4, YP1 to YP10) installed at regular intervals. Each of the light emitting device arrays XL1 to XL4 and YL1 to YL10 configured as described above is driven to emit light in accordance with the X axis and Y axis driving signals and the light receiving device arrays XP1 to XP4 and YP1 to YP10 are driven by the light emitting device arrays XL1 ~ XL4, YL1 ~ YL10).

In the above embodiment, three elements are provided in the light emitting element arrays XP1 to XP4, YP1 to YP10 and the light receiving element arrays XP1 to XP4, YP1 to YP10. However, in order to increase the sensing sensitivity, It is obvious that many can be installed.

Fig. 14 is a block diagram showing the configuration of the optical pickup device in which the optical element arrays XL1 to XL4 and YL1 to YL10 of the ball sensing gate BSG shown in Fig. 13 are driven and the outputs of the light receiving element arrays XP1 to XP4 and YP1 to YP10 are read, 12), and displays a score counter (SCNT) for announcing a score in accordance with the ball speed of the practice ball detected by the speed gun (SG).

14, the score counter SCNT includes a plurality of light emitting element arrays XLi and YLj (where i is '1 to 4') arranged on the X axis and the Y axis of the ball sensor gate BSG by the emission control signal, emitting elements Xl and YLj of the X-axis and the Y-axis of the ball sensing gate BSG are disposed on opposite surfaces of the light-emitting driving elements LD1 and LD2, respectively, An optical receiver PR1 and PR2 for reading the outputs of the light receiving element arrays XPi and YPj for receiving a light source (or an infrared ray) projected from the light emitting element arrays XLi and YLj; Light emitting element arrays XLi and YLj provided on the X axis and the Y axis of the ball sensor gate BSG are turned on and the light receiving element arrays XPi and YPj provided on the X axis and Y axis of the ball sensor gate BSG ) Of the goal post (12) or the ball sensor gate (BSG) after determining the ball passage area of the goal post (12) by the signal output from the optical receivers (PR1, PR2) A score controller SCNT for converting the score by an output of an impact signal output from an impact sensor IS and an output of a speed gun SG provided at the rear of the goal post 12, And an indicator (DISP) for displaying the score externally. Although the embodiment of the present invention has been described to include the light emitting drivers LD1 and LD2 and the optical receivers PR1 and PR2, the score controller SCNT controls the light emitting element arrays XLi and YLj to be integrated and driven, It is not necessary to include the outputs of the arrays (XPi, YPj) in an integrated manner.

13 and 14, the operation of converting the score when the practice ball passes through the goalpost will be described.

When the soccer practice apparatus 1 is operated, the score controller SCNT shown in FIG. 14 provides a light emission control signal to the light emission driving units LD1 and LD2 to generate a light emission control signal in synchronization with the X axis of the ball sense gate BSG shown in FIG. The light emitting element arrays XLi and YLj provided on the Y axis are all turned on. At this time, all the light emitting elements in the light emitting element arrays (XLi, YLj) disposed on the left side of the X axis and the upper side of the Y axis are turned on, and the light due to the lighting is connected to the light receiving element arrays XPi, YPj). At this time, the rays XPi and YPj receive the light reflected by the light emitting device arrays XLi and YLj and input the detected signals to the optical receivers PR1 and PR2.

Since the ball 12 is not normally inserted into the goal 12, the light beams emitted from the light emitting device arrays XLi and YLj provided on the left side of the X axis and the upper side of the Y axis are provided as rays XPi and YPj to the light receiving elements without interruption. Therefore, when the ball does not enter the ball 12, the signals detected by the rays XPi and YPj are all the same in the light receiving element, and the detection signal is transmitted to the score controller SCNT through the optical receivers PR1 and PR2 / RTI >

The score controller SCNT senses whether or not the detection signals of the rays XPi and YPj are blocked by the light receiving elements received through the optical receivers PR1 and PR2 and determines which region of the goal 12 has passed the ball . If the ball does not pass through the goal 12, the detection signals of the rays (XPi, YPj) are not activated (logical "high") in the light receiving element so that the goal is not recognized.

When the practitioner's shot passed through the "A" zone of FIG. 13, the light illuminated from the light emitting device arrays XL1, YL1 is momentarily blocked by the practice ball passing through the "A" zone, (Logic "low") occurs only at the output of the scan drivers XP1 and YP1, which is provided to the score controller SCNT via the optical receivers PR1 and PR2. At this time, the score controller SCNT recognizes that the output of the two photoreception arrays XP1, YP1 is inactive and passes the "A" zone of FIG. 13, Quot; 10 "points.

Then, the score controller (SCNT) reads the speed information of the practice ball detected at the speed gun (SG) installed at the back of the goal 12 and gives a weight according to the speed information to the goal passing score "10 & The passing score is confirmed, and the practitioner passing area and the passing score are displayed by the indicator (DISP), and the practitioner confirms to which part of the ball the ball was drawn. Therefore, practitioners can be more interested in practice. In the above, the weight is defined as 1 if the speed of the ball is greater than or equal to 60 Km / h, and 0.5 if the ball is less than 60 Km / h.

If the practice ball shot by the practitioner passes through the "A" and "B" areas of the ball sensing gate (BSG), the average value of the two areas is determined as the goal passing score, and the weight according to the speed sensed by the speed gun And displays the score of the governing passage on the display device DISP. If the impact sensor IS installed on the goal 12 detects an impact while the ball is inserted into the passing area of the ball sensor gate BSG, the score controller SCNT passes through the ball Regardless of the zone, the goal score is indicated as '10'.

As described above, the soccer practice apparatus according to the present invention is a soccer practice apparatus in which, when a practitioner shoots a ball toward a goal, it detects the passing area of the goal and the ball speed, displays the passing area of the goal and the score of the goal, The player has the advantage of being more interested in exercising, and can easily recognize where the ball he or she has passed through the ball, so that the shoot position can be calibrated more quickly.
