Description

A moving object blocking system and its method {SYSTEM FOR BLOCKING MOVING OBJECT AND THE METHOD THEREOF}

The present invention relates to a moving object blocking system and method thereof, and more particularly, by connecting a net to a telescopic pipe set in which at least one or more pipes of different diameters are accommodated, and in a state of being installed low near the ground. If the net needs to be unfolded, the telescopic pipe set is quickly elongated in the vertical direction and the net is deployed in the air, so that it can be quickly applied to sports items and main facilities, including balls flying from the stadium to the stand It relates to a moving object blocking system and method for blocking a moving object including an approaching flock or a drone.

In general, a ball hit by a batter in a baseball field quickly flies into the spectator's seat by line drive. The weight of a baseball is about 140 grams, and the speed of the ball hit by a batter is close to a maximum of 200 km/h, so if a baseball flying into the spectator's seat hits a part of the spectator's body, it can lead to injury or death in severe cases. have. For example, if it collides with the head, the skull collapses and dies, or if it hits the eye, the risk of blindness is high. In particular, since there are many family members in the baseball field, children and women who are less capable of responding to balls flying into the stands are relatively damaged. The number of people injured by foul balls in the ballpark is by no means small, reaching thousands of people every year worldwide, and the impact of these accidents may reduce the family spectator and cause the overall spectator to decline.

Therefore, in most baseball fields, nets are installed to prevent injury from the ball. For example, the spectator seats in a baseball field are divided into infield and outfield seats, and the infield seats can be divided into first, third, and center seats at the back of the at-bat seat. However, there are ballparks that do not have nets in some of the spectators on the first and third base sides to ensure visibility of the spectators, while there are also ballparks with nets 10 to 20 meters high for safety. The purpose of installing the net is mainly to prevent injuries caused by foul balls flying low and fast toward the stands. A ball that rises above the net is usually a foul ball flying in a parabolic shape, so it is relatively slow when it falls and does not cause fatal injuries. Therefore, most fatal injuries can be prevented with a net 10 to 20 meters above the ground.

However, since the above nets obstruct the view of a large number of infield spectators, spectators who expect a wide and blue playground with an open and clear view will have to look at the baseball field through a flickering net in front of them. This causes the satisfaction level to drop significantly. Moreover, in places with low infield seats that must be viewed through the net, admission fees are often higher than those in outfield seats, resulting in lower relative satisfaction. For this reason, many baseball fields hesitate to install nets on some of the first and third bases.

In addition to baseball fields, there are many places where it is necessary to have a device to block a ball or a puck that suddenly and unexpectedly flows in order to reduce the risk of injury to the spectators or game personnel such as ice hockey and golf courses. The present invention was created by reflecting these needs (needs).

Meanwhile, in recent years, drones are widely used in daily life and industrial fields, and drones have begun to be used in the military field as well. The drones are inexpensive and relatively easy to make, so they are highly likely to be used for terrorism or local warfare.Since they are smaller than airplanes, they are indistinguishable from birds or flocks if they are far away, and even if they are found close, it is difficult to find appropriate intercepting means. . In addition, flocks of birds flying in groups can damage crops, grain storage, and airplane runways. In particular, flock of birds entering near the runway of airplanes can cause fatal damage if they collide with the engine of a jet airplane.

In this way, nets can be installed near important facilities or runways to prevent damage from drones or birds. Since most of the places where nets are installed are outdoors, if nets are installed on fixed structures, these structures and nets must withstand snow, rain, wind, sunlight, and temperature changes. In particular, in case of strong winds, the structure must be strong, and the net must not be torn or blown away by the wind. As the installation site grows, this is not only expensive, but also very difficult to manage.

Therefore, in order to prevent possible damage from drones or birds, it is usually installed on the ground or inside a facility on the ground to minimize the effects of snow, rain, wind, sunlight, etc., and judged with the naked eye of a radar or human When a flock of birds appears, it is necessary to reduce the installation cost and facilitate operation and management by spreading the net and preparing for the situation.

Therefore, in the present invention, a net is connected to a telescopic pipe set in which at least one pipe of a different diameter is accommodated, and the net is normally installed in a low installed state near the ground, but when the net is to be unfolded, pneumatic pressure, hydraulic pressure, and elastic body , The telescopic pipe set is rapidly elongated in the vertical direction through a wire or a combination thereof to expand the net into the air, thereby blocking a moving object including a ball, a flock of birds, or a drone to collide with the moving object. It is intended to prevent damage to human life or major facilities caused by, and to suggest measures to prevent intrusion.

For example, in the case of a baseball field, it is usually installed low within 1 to 2 meters and does not interfere with the visibility of the spectators, and only the moment the foul ball comes in, quickly spreads the net 10 to 20 meters into the air and catches a flying baseball. By doing so, the purpose of preventing damage caused by foul ball and securing the viewing field can be achieved. At this time, the determination of spreading the net may be performed by a person or may use a radar that tracks the speed and direction of the baseball.

1 is a diagram showing the configuration of a moving object blocking system according to an embodiment of the present invention.

As shown in Fig. 1, the moving object blocking device 100 of the present invention spreads a net in the air when necessary, and sports articles (balls, puck for ice hockey, baseball bats) including foul balls flying quickly from the baseball field to the stands. , Golf clubs, etc., including all items that may injure spectators or game personnel), for blocking the invasion of fast-flying drones or birds, telescopic pipe set 110, net 120, moving objects It includes a sensing means 130, a control means 140, a driving means 150, an input operation means 160, and the like.

In addition, although the moving object blocking device 100 is not shown in the drawing, a power supply unit that supplies operation power to each component, a memory storing various operation programs, and the telescopic pipe set 110 are not accessible by people or animals. A safety fence that blocks the access, a proximity sensor and a warning device for detecting and warning the approach of people or animals, attached to the outside of the telescopic pipe set 110 or installed at a predetermined distance outside the telescopic pipe set 110 It may further include a buffer member that is unfolded or folded according to the elongation of the telescopic pipe set 110 to prevent damage by direct hitting the moving object.

The telescopic pipe set 110 is provided with at least one pipe having a different diameter and is installed in a vertical upward direction with one side fixed to the ground or a facility, and spaced apart at a predetermined interval to be installed at least one or more.

At this time, the telescopic pipe set 110 is formed using materials such as carbon, titanium alloy, plastic, iron, copper, aluminum, etc. to increase lightness and rigidity, and the shape of each pipe is based on a circle, and various types such as triangles and squares. Can be made into shape.

In addition, the telescopic pipe set 110 may be used in a wider range by increasing the quantity or increasing the distance between each telescopic pipe set 110, and to use it to a higher range, the length of each pipe and the net 120 You can increase the height.

In the moving object blocking device according to the present invention, one side of the net is fixed to the ground, and the other side is connected to the telescopic pipe set 110 so that the net is deployed in an inclined manner. In this case, in the baseball field, the infield can be formed with a high net, and the net can be formed inexpensively so that the net can be formed lower as the outfield goes. In addition, it is possible to configure the net and the telescopic pipe set in various shapes, such as installing them to face each other or forming them sequentially. In addition, it is possible to control the deployment of the net according to the overall configuration of the moving object blocking device.

The structure of the telescopic pipe set 110 will be described in more detail with reference to FIGS. 2 and 3 as follows.

2 is a view for explaining the structure of a telescopic pipe set according to an embodiment of the present invention, Figure 3 is a cross-sectional view for explaining in detail the detailed structure of the telescopic pipe set according to an embodiment of the present invention.

As shown in (a) of FIG. 2, the telescopic pipe set 110 is a structure in which pipes 111 having different diameters are housed inside. For example, in the case of using three pipes, the diameter is It is constructed in such a way that the second largest diameter pipe is placed in the largest pipe, and the third largest diameter pipe is placed in it again.

In addition, the telescopic pipe set 110, as shown in Figure 2 (b), when all the lengths of the n pipes are the same, if all pipes with a small diameter are put in the pipe with the largest diameter, the length of one pipe becomes the same. If the length is increased in the direction perpendicular to the ground, the total length of the pipe becomes about n times the length of the pipe.

As such, when the telescopic pipe set 110 is extended in the vertical upward direction, each pipe must be configured so that it does not fall out. To this end, the telescopic pipe set 110 may apply various methods as shown in FIG. 3, and three methods are applied as follows. At this time, the present invention proposes three methods, but is not limited thereto, and it is noted that various methods can be applied.

First, as shown in (a) of FIG. 3, the diameter of each pipe 111 constituting the telescopic pipe set 110 is formed to decrease from the bottom to the top, but the upper inner diameter of the pipe located outside is It is formed to be smaller than the lower outer diameter of the pipe accommodated in the inner side of the pipe located outside. When each pipe 111 is formed in this way, when the telescopic pipe set 110 is extended in the vertical upward direction, the lower part of the pipe accommodated in the inner side and the upper part of the pipe located at the outer side engage with each other so that the pipe does not fall out. Will not be. At this time, it is necessary to immediately fold after each pipe 111 is stretched. In this case, it can be easily folded by the weight of each pipe 111 and the weight of the net 120 connected to the pipe 111.

Second, as shown in (b) of FIG. 3, among the pipes 111 constituting the telescopic pipe set 110, only a stopper 112 is formed on the inner surface of the upper end of the pipe having the largest diameter. A stopper 112 and a locking protrusion 113 are formed on the inner side of the upper end and the outer circumference of the lower end of at least one pipe accommodated in the pipe having the largest diameter, respectively, and the locking protrusion 113 is formed on the outer circumference of the lower end of the pipe with the smallest diameter ) Only. When the stopper 112 and the locking projection 113 are formed in each pipe 111 in this way, when the telescopic pipe set 110 is elongated in the vertical upward direction, the stopper 112 formed in the pipe having a large diameter has a diameter The locking protrusion 113 formed in the small pipe may be caught, and the pipe 111 may be prevented from falling out. In addition, after each pipe 111 is stretched, it can be easily folded by the weight of each pipe 111 and the weight of the net 120 connected to the pipe 111.

Third, as shown in (c) of FIG. 3, a wire 114 for preventing separation of a length shorter than the length of at least one or more pipes 111 accommodated in the telescopic pipe set 110 is inserted into each pipe 111 ) Formed by connecting at least one or more. When the separation prevention wire 114 is connected to each pipe 111 in this way, when the telescopic pipe set 110 is extended in the vertical upward direction, the pipe 111 is externally formed by the separation prevention wire 114 It can be prevented from falling out, and can be easily folded by the weight of each pipe 111 and the weight of the net 120 connected to the pipe 111 after each pipe 111 is increased.

At this time, it is preferable to use two or more wires for separation prevention 114, the reason is to balance the pipe 111 and reduce the amount of impact applied to the separation prevention wire 114. This is because, for example, if there is one separation prevention wire 114, when the pipe 111 is unfolded, an impact can be applied to only one side of the pipe 111. In addition, since a large impact is applied when the pipe 111 is unfolded as the separation prevention wire 114 becomes taut, the separation prevention wire 114 must have strength to withstand this, and must be firmly fixed.

Referring back to FIG. 1, the net 120 is connected to the pipe 111 constituting the telescopic pipe set 110, and when the telescopic pipe set 110 is elongated, it expands into the air and Or, it blocks the movement of moving objects including drones.

At this time, the net 120 is formed of a tough, light and sturdy material such as nylon and polyester so that it is not damaged even when a moving object at a high speed comes into contact, and the net spacing is designed to be smaller than the size of the moving object to be blocked. Should not be allowed to escape.

In addition, when a plurality of the telescopic pipe sets 110 are used, the net 120 is connected between the pipes 111 constituting the telescopic pipe set 110, and only one telescopic pipe set 110 is used. When used, one side may be connected to the pipe 111 constituting the telescopic pipe set 110 and the other side may be fixed to a fixture spaced a predetermined distance.

The structure of the net 120 will be described in more detail with reference to FIGS. 4 and 5 as follows.

4 is a view for explaining that the net is spread through the extension of a telescopic pipe set according to an embodiment of the present invention, and FIG. 5 is a view for explaining a structure of a folded portion of the net according to an embodiment of the present invention to be.

As shown in FIG. 4, the net 120 is connected to each pipe 111 of the telescopic pipe set 110, and waits in a folded state when the telescopic pipe set 110 is not operating. When the telescopic pipe set 110 is extended in the vertical upward direction, it is deployed high in the air.

As described above, when the net 120 is deployed in the air, if the net 120 is used as one, the telescopic pipe set 110 must support all the weight of the net 120, so it can bend and move quickly. Since there is a possibility that the object may move a considerable distance to the other side while dragging the net 120, it is preferable to connect it to several pipes 111 as much as possible.

In addition, as shown in FIG. 5 when the net 120 is folded, when a folded portion 121 made of a material that is harder, more elastic and thicker than the net 120 is formed in the horizontal direction in the middle portion, the moving object causes the In addition to preventing the net 120 from being pushed, it is helpful in orderly folding while reducing the area of the net 120.

Referring back to FIG. 1, the moving object detecting means 130 detects the direction and speed of the moving object and transmits a detection signal to the control means 140. At this time, the moving object detection means 130 uses an Industry Science Medical (ISM) band radar that uses a frequency permitted for general industrial, scientific, and medical purposes, and the trajectory (that is, the speed and the trajectory of a flying baseball, a flock of birds, and a drone) is used. Direction, etc.). In the present invention, at least one or more may be used depending on the location used.

When a moving object approaches, the control means 140 controls to transmit a driving force through pneumatic pressure, hydraulic pressure, elastic body, wire, or a combination thereof to the telescopic pipe set 110 through the driving means 150, The telescopic pipe set 110 is elongated in a vertical upward direction to expand the net 120.

At this time, the control means 140 controls the net 120 to be automatically deployed according to the direction and speed of the moving object sensed by the moving object detection means 130, or received input from the input operation means 160. The net 120 can be controlled to be deployed according to the user's manual operation.

In addition, the control means 140 controls release of the driving force transmitted to the telescopic pipe set 110 through the driving means 150 when a predetermined time elapses, so that each pipe of the elongated telescopic pipe set 110 As is the original position, the developed net 120 is folded.

The drive means 150 is configured to include a compressor, a motor, an actuator, etc., which are pressure generating means for generating pressure by compressing air or fluid, and according to the control of the control means 140, pneumatic pressure, hydraulic pressure, elastic body, A driving force through a wire or a combination thereof is transmitted to the telescopic pipe set 110 so that the telescopic pipe set 110 is extended in a vertical upward direction so that the net 120 is unfolded. When a predetermined time elapses, the telescopic pipe set 110 The pipe set 110 is folded to place the net 120 in its original position.

The operation process of the driving means 150 will be described in more detail with reference to FIGS. 6 to 9 as follows.

6 to 8 are cross-sectional views for explaining the elongation of the telescopic pipe set by compressed air, the elongation of the telescopic pipe set by an elastic body, and the elongation of the telescopic pipe set by the pipe moving wire connected between the pipes, and FIG. 9 is A diagram showing an example of a driving means of a moving object blocking system according to an embodiment of the present invention.

As the driving method of the driving means 150, a method using pneumatic pressure, a method using an elastic body, a method using a wire, etc. are applied as follows, but various methods such as a method using a hydraulic pressure may be used.

First, as shown in FIG. 6, when the driving method using pneumatic pressure is described, the driving means 150 is less than atmospheric pressure through a supply pipe connected to the lower portion of the telescopic pipe set 110 under the control of the control means 140. By supplying high compressed air, the pipe accommodated in the telescopic pipe set 110 is elongated in a vertical upward direction, and when a predetermined time elapses, the supply of the compressed air is reduced or blocked, and the elongated telescopic pipe set ( 110) to the original position.

In this process, the compressed air may escape due to the gap between the pipes of the telescopic pipe set 110 and the force to push the pipe may be insufficient, so that the gap between the pipes is appropriately set, and the compressed air escapes through the gap. If compressed air is continuously supplied even if it goes out, the air pressure in the telescopic pipe set 110 can be maintained so that normal operation can be performed.

For example, assuming that the pipe thickness is 0.8mm, the number of pipes is 5, and the spacing between the pipes is 0.1mm, when the outermost pipe diameter is 20mm, it becomes 19, 18, 17, 16mm in turn. The inner cross-sectional area of the pipe with the largest diameter is about 289 mm ² . There are 4 circular gaps with 0.1mm spacing between each pipe, and their cross-sectional areas are about 6mm ² , 5.7mm ² , 5.4mm ² , and 5.1mm ^{2 respectively} , and the total area of the gap is about 22mm ² . Then, the area of the gap is about 7.6% of the total internal area, and the area of 92.4% is closed. Accordingly, when compressed air is supplied from the driving means 150, the air escapes through the gap area of 7.6%, and the area of 92.4% will receive a force to push upward.

In addition, each pipe of the telescopic pipe set 110 must be sequentially and consistently elongated in a vertical upward direction by the compressed air supplied from the driving means 150. This is because if the order in which each pipe is stretched is not constant, problems such as tangling or getting caught when the net 120 connected to each pipe is unfolded occurs. To this end, in the present invention, the innermost pipe of the telescopic pipe set 110 is formed in a form where the inside is blocked or filled, or even if a small hole is formed at the end of the pipe, it is The valve (funnel) is formed to receive pressure, and the remaining pipes are formed with the top and bottom open, so that the pipe located at the innermost side by the compressed air supplied from the driving means 150 is the largest of the compressed air. It is preferable that the force is first elongated in the vertical upward direction, and the other pipes are sequentially elongated from the inside to the outside.

For example, the force that the pipe tries to escape is primarily proportional to the area of the surface perpendicular to the input compressed air. Since the outermost pipe is fixed, it is only necessary to consider the pipe that is accommodated inside it. The force that the pipe receives by the compressed air is primarily proportional to the direction in which the compressed air flows and the area of the pipe face perpendicular to that direction. The area is equal to the area obtained by subtracting the area by the inner diameter from the area by the outer diameter of the pipe. As in the above example, the diameter of the second pipe is 19 mm and the thickness is 0.8 mm, and the contact area of the pipe is about 23 mm ² . The third and fourth pipes are 22 and 21 mm ² by the same calculation. On the other hand, the innermost pipe is blocked, so the area is 20mm ² . Therefore, the area of the innermost pipe subjected to the force of compressed air is 70% of the total inner area of the pipe with the largest diameter. In addition, the innermost pipe has the smallest diameter, so it weighs the least if the length and thickness are the same. Accordingly, the pipe located on the innermost side will start to exit the first. At this time, each of the pipes does not completely escape and is caught by the separation prevention wire 114, etc., so that the air pressure applied to the pipe located at the innermost side tries to escape and is connected to the part caught at the end, that is, the second pipe is allowed to escape. Acts as a force And around the time the second inner pipe is almost pulling out, it gets caught in the third pipe, and the third pipe begins to come out on the same principle. Even if this process is not completely caused by friction or other factors, it will be pulled out sequentially from the innermost pipe based on the force under pneumatic pressure.

In addition, if air pressure is continuously applied while the pipes of the telescopic pipe set 110 are all vertically elongated, the pipes may be damaged due to high pressure or repeated operation. Accordingly, in the present invention, a compressed air discharge unit 115 is formed on the outermost pipe of the telescopic pipe set 110, and when the air pressure inside the telescopic pipe set 110 increases, the compressed air is discharged to the outside. Thus, the air pressure inside the telescopic pipe set 110 is kept constant. That is, when each pipe accommodated in the telescopic pipe set 110 is folded, the compressed air discharge unit 115 does not play a large role because it is blocked by the second pipe, but after the second pipe is vertically extended, the telescopic pipe This is to prevent the air pressure inside the set 110 from becoming larger than necessary.

Meanwhile, the driving means 150 is a high-pressure pump 151 that generates high-pressure compressed air or fluid (which is an example of a pressure generating means that generates pressure through air or fluid), as shown in FIG. A storage tank 152 for storing high-pressure compressed air or fluid generated by the pump 151, the high-pressure compressed air stored in the telescopic pipe set 110 by being opened under the control of the control means 140, or Solenoid valve 153 supplying fluid (an example of a valve supplying the air or fluid to the telescopic pipe set), reverse flow to prevent reverse flow of compressed air or fluid when the high pressure pump 151 is not operating When the use of the prevention valve 154 and the moving object blocking device 100 is terminated or not used for a long time, a discharge valve 155 for releasing compressed air or fluid inside may be included.

Here, the pressure generating means and the valve may be provided for each of the telescopic pipe sets, or may be provided in common for a plurality of the telescopic pipe sets.

At this time, the moving object blocking device 100 must be operated quickly within a very short time of about 0.5 seconds, so the high pressure pump 151 is operated at the moment when the net 120 is to be deployed to reduce compressed air or fluid. Since time may be insufficient to supply, it is preferable to operate the high-pressure pump 151 in advance, put it in the storage tank 152, and then open the solenoid valve 153.

In addition, when two telescopic pipe sets 110 are used, if the operation is inconsistent and one telescopic pipe set is all extended, but the other telescopic pipe set has not yet been extended, the net connected to the pipe 111 There is a risk that a part of the pipe of the telescopic pipe set 110 may be bent or broken due to the 120, and the net 120 may be damaged. Therefore, preferably, all telescopic pipe sets 110 should be stretched simultaneously. If the distance between the telescopic pipe sets 110 is long, it is difficult to mechanically match the operation, so in the present invention, the high pressure pump 151, the storage tank 152, the solenoid valve 153, and the non-return valve It is preferable to install the driving means 150 including the 154 and the discharge valve 155 for each of the telescopic pipe sets 110.

On the other hand, as shown in FIG. 7, when explaining a driving method using an elastic body, the telescopic pipe set 110 is between an outer upper end of a pipe having a small diameter accommodated in a pipe having a large diameter and an inner lower end of the pipe having a large diameter. An elastic body 116 that is installed in the telescopic pipe set 110 in a vertical upward direction by maintaining the compressed state in a non-operating state, and when the compressed state is released, the pipe accommodated in the telescopic pipe set 110 It can be configured to include.

In addition, the driving means 150 pulls the elastic body driving wire 117 connected to the upper end of the telescopic pipe set 110 under the control of the control means 140 to maintain the compressed state of the elastic body 116, In the present state, when the moving object is close and the net 120 needs to be deployed, the force applied to the elastic body driving wire 117 is released according to the control of the control means 140 to release the force applied to the elastic body 116. Each pipe of the telescopic pipe set 110 is elongated in a vertical upward direction by the compressed force.

In addition, when a predetermined time elapses, the driving means 150 compresses the elastic body 116 while pulling the elastic body driving wire 117 back to position each pipe of the elongated telescopic pipe set 110. .

Meanwhile, as shown in FIG. 8, when a driving method using a wire is described, the driving means 150 may have a structure such as an elevated ladder called a boom. In this case, the telescopic pipe set 110 may include a pipe moving wire 118 connecting the driving means 150 and at least one or more pipes accommodated in the telescopic pipe set 110.

In addition, when the moving object is close and the net 120 needs to be deployed, the driving means 150 grabs the pipe moving wire 118 connected to the pipe having the largest diameter under the control of the control means 140. Pull and lift the n-th pipe housed in the pipe with the largest diameter, and the n-th pipe pulls the pipe moving wire connecting between the n-1-th pipe and the n+1-th pipe, and the n+1-th pipe To the telescopic pipe set 110 by lifting the n+1th pipe and pulling the pipe moving wire connecting between the nth pipe and the n+2th pipe to lift the n+2th pipe. Each received pipe should be lifted sequentially.

In addition, when a predetermined time elapses, the driving means 150 releases the force applied to the pipe moving wire 118 to bring each pipe of the elongated telescopic pipe set 110 to its original position.

Meanwhile, the method of extending the telescopic pipe set 110 in the vertical upward direction by using a method using pneumatic pressure, an elastic body, a wire, etc. through the driving means 150 is any one method depending on the installation location and the use environment. Or it can be applied in combination of these. At this time, if a number of methods are applied, the failure factor increases and the manufacturing cost increases. Therefore, the usage method must be decided in consideration of this.

Referring back to FIG. 1, the input manipulation means 160 outputs a user's manipulation signal, which has confirmed the direction and speed of the moving object, to the control means 140.

The detailed configuration of the input operation means 160 will be described in more detail with reference to FIG. 10 as follows.

FIG. 10 is a diagram showing an example of an input operation means of a moving object blocking system according to an embodiment of the present invention, which is used when extending the telescopic pipe set 110 by compressed air.

As shown in Fig. 10, the input operation means 160 includes a mode selection switch 161 for selecting automatic operation by the moving object detection unit 130 or manual operation by the user, and the movement of the moving object is A standby switch 162 for selecting not to operate the moving object blocking device 100 during an absence of time, and an operation switch 163 for inputting an operation signal for deploying the net 120 according to the proximity of the moving object And a compressed air release switch 164 for releasing compressed air after the use of the moving object blocking device 100 is terminated.

At this time, it is revealed that the configuration of each switch can be changed and used according to the operation method of the driving means 150.

On the other hand, the moving object blocking device 100 may be configured to operate by automatically detecting a moving object through a radar, or configured to operate manually by a person seeing a moving object visually and judging it, or a combination of the two methods. have. A method that operates automatically through a radar may have a fast reaction speed, but it may be difficult to cope with an unexpected situation, and a method that is operated manually by a person may have a slightly slower reaction speed, but a comprehensive situation judgment ability can be expected.

The input operation means 160 is used when a person manually operates the driving of the moving object blocking device 100, or when a combination of automatic and user's manual operation using a radar is used.

Next, an embodiment when the moving object blocking device according to an embodiment of the present invention configured as described above is used in a baseball field will be described in detail with reference to FIGS. 11 to 13.

11 is a view showing an example of installation of a moving object blocking system in a baseball field according to an embodiment of the present invention, and FIGS. 12 and 13 are air and atmosphere in the baseball field of the moving object blocking system according to an embodiment of the present invention. It is a diagram showing each operation state.

As shown in Fig. 11, the moving object blocking device 100 of the present invention is preferably installed between the poles of the foul from the end of the player waiting area (dugout) on the first and third base sides of the baseball field.

The length from the dougout to the pole of the foul is different for each baseball field, but assuming that it is about 50 meters, the height is assumed to be 10 meters when the net 120 is unfolded, and the telescopic pipe set 110 is installed at intervals of 10 meters. Is assumed to be. Then, six telescopic pipe sets 110 are required to install 50 meters, and the width of the net 120 between the telescopic pipe sets 110 is 10 meters. In addition, since the pipe must be stretched to a height of 10 meters, at least 10 pipes are used, and the telescopic pipe set 110 should not interfere with the view when folded, so that between 1 and 1.5 meters similar to the existing fence height is suitable, The pipe must be fixed to the ground, and the rest of the pipes are normally housed in it except for a portion of the upper part of the pipe. In other words, the present invention is not present in the field of view so as not to interfere with watching the game in normal times, but only when an event occurs, it is deployed in the air to block the moving object.

In the embodiment of the present invention, when the foul ball flies, it flies in either the first-base side or the third-base side, so only the moving object blocking device 100 in the corresponding direction needs to be operated. At this time, since an error may occur in predicting the trajectory of the ball or there may be an unexpected variable such as wind blowing, the first-base side and the third-base side moving object blocking device 100 may be simultaneously operated.

In addition, the foul ball flying higher than the net 120 having a height of 10 meters is much less intimidating than the foul ball flying in a low straight line since it usually flies in a parabolic line, and accordingly, the moving object blocking device 100 is near the ground as shown in FIG. Stand by while maintaining the low installed state.

In this way, when a case occurs in which the net needs to be spread while waiting in a low-mounted state near the ground, the foul ball is caught in the net 120 by operating the moving object blocking device 100 as shown in FIG. 13. That is, when the foul ball flies in a straight line into the audience seat, the moving object detection means 130 detects it, and the telescopic pipe set 110 through the driving means 150 according to the control of the control means 140 As is elongated, the net 120 is deployed in the air, and the foul ball is blocked by the net 120. At this time, a person may visually determine the movement of the moving object to operate the moving object blocking device 100.

Next, an embodiment of a method for blocking a moving object according to the present invention configured as described above will be described in detail with reference to FIG. 14. At this time, the order of each step according to the method of the present invention may be changed by a use environment or a person skilled in the art.

14 is a flow chart showing in detail an operation process of a method of blocking a moving object according to an embodiment of the present invention.

First, the control means 140 of the moving object blocking device 100 performs a net deployment determination step of determining whether or not the moving object is close and it is necessary to deploy the net 120. That is, the control means 140 checks the direction and speed of the moving object (S100), and determines whether or not deployment of the net 120 is necessary (S200).

At this time, the control means 140 compares the direction and speed of the moving object detected by the moving object detection means 130 with a preset direction and speed, and whether the direction and speed of the moving object exceeds a preset direction and speed. According to whether or not deployment of the net 120 is necessary according to whether or not, or according to whether an operation signal for deploying the net 120 is input from the input operation means 160 according to the user's manual operation. It is determined whether or not deployment of the net 120 is necessary.

As a result of performing the net deployment determination step through the steps S100 and S200, if the net 120 needs to be deployed, the control means 140 vertically moves the telescopic pipe set 110 through the driving means 150. A net expansion step of expanding the net 120 is performed by extending in the direction (S300).

That is, the driving means 150 transmits driving force through pneumatic pressure, hydraulic pressure, elastic body, wire, or a combination thereof to the telescopic pipe set 110 according to the control of the control means 140, and the telescopic pipe set 110 Is to be stretched in the vertical upward direction so that the net 120 is deployed.

Then, a moving object blocking step of blocking the moving object through the net 120 deployed in the air through the step S300 is performed (S400).

In addition, after blocking the moving object through the expanded net 120 through the step S400, the control means 140 determines whether a predetermined time has elapsed (S500), and when a predetermined time has elapsed, the driving means ( By 150), each pipe of the elongated telescopic pipe set 110 is returned to its original position to perform the net original position step of folding the expanded net 120 (S600).

As described above, the present invention can effectively block moving objects such as a flock of birds or drones that quickly approach major facilities, including sports items including balls flying from the stadium to the spectators by line drive, by rapidly deploying the net in the air when necessary. Accordingly, it is possible to prevent damage to people or major facilities due to collision with the moving object, as well as to prevent invasion of birds or drones.

As described above, the present invention has been described with reference to the embodiments shown in the drawings, but this is only exemplary, and various modifications and equivalent other embodiments are provided from those of ordinary skill in the field to which the technology belongs.
