Description

The method of intercepting small unmanned aircraft

The present invention relates to a method of intercepting a small unmanned aerial vehicle, and more particularly, when an enemy air vehicle appears in a domestic airspace, an interceptor with hooks or a net installed to intercept the air vehicle intercepts the interceptor, It is possible to increase the intercept efficiency by ensuring that the target on the object is tracked through the imaging device installed in the interceptor while intercepting it in the approaching state, and it is possible to reuse the interceptor by allowing the interceptor to be recovered even if the interception to the object is failed. The present invention relates to an intercept method of a small UAV.

Generally, in order to shoot down an enemy airplane, a missile is usually launched to collide with a missile to collide with the airplane. However, this results in a remarkably different shooting rate depending on the price of the missile, There has been a problem in that it takes a lot of cost to shoot down.

Therefore, after grasping the approach of the enemy air vehicle in the ground control unit as disclosed in Korean Patent Laid-Open No. 10-2010-0068134, the enemy air vehicle is shaken by the vibration generated by the ultrasonic wave by emitting the ultrasonic wave to the air vehicle.

However, as described above, the ultrasonic waves used in shooting the air vehicle at a long distance may be weakened according to the distance, or may be interfered with other radio signals, and errors may occur in the signal, Malfunctions of other electronic apparatuses or the like at the adjacent points to which the radio waves are radiated can be caused, and there is a problem in that it can cause harm to the allied forces.

The method of intercepting a small unmanned aerial vehicle of the present invention detects an airborne object emerging from the ground control unit to generate an alarm, confirms and tracks the position of the corresponding airborne object, sets the target, generates information, A step of inputting the information to an interceptor, a step of taking off the interceptor by information and control generated by the terrestrial control unit, sensing the position of the object in real time in the terrestrial control unit and transmitting the information to the interceptor, An interception step of intercepting the air vehicle by performing an automatic flight when the air vehicle is detected as a target in the image device installed in the body of the air vehicle approaching the air vehicle, After the step, if the interceptor fails to intercept the air vehicle, And the new interceptor is carried out so as to be able to intercept the flight body, so that the interception rate can be increased by intercepting the body in the state where the interceptor is close to the flight body by using hooks or nets installed on the body through the additional intercepting step It is possible to reduce the damage to the civilian, and it is necessary to accurately determine the target of the flight through the imaging device installed in the body of the interceptor, and then to intercept it by approaching the body of the flight so as to increase the interception rate to the body, If there is a failure of the first interceptor to the flight body, it can be intercepted again while tracing the flight body once or three times repeatedly. Even if one interceptor fails the interceptor, the new interceptor is taken off again, The purpose is to make it possible.

The present invention is advantageous in that an interceptor is interposed in a state in which an intruder is close to a flight body by using a hook or a net installed on the body, thereby increasing the interception rate of the flight body and reducing the damage to the civilian.

Also, it is advantageous to increase the interception rate to the airplane by allowing the airplane to approach the airplane after the airplane is accurately targeted through the video device installed in the interlocking body.

In addition, if a hook is formed instead of a net in the body of an interceptor, the interceptor can be traced again while tracking the body one to three times, even if the first interceptor fails, and even if the interceptor fails, There is an advantage that the interceptor can be taken off again and the interception of the air vehicle can be re-executed.

In addition, there is an advantage that the body can be recovered safely through the parachute installed on the body of the body to reuse the body.

1 is a flowchart showing an intercepting method of a small unmanned aerial vehicle according to the present invention.

In order to achieve the above object, the present invention is as follows.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method of intercepting a small unmanned aerial vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in FIG. 1, the ground control unit continuously monitors whether an enemy air vehicle appears as a friendly airspace. (S10)

Then, when the enemy's airspace is detected as the enemy's airspace, the enemy airplane is alerted to the appearance of the enemy airplane and the enemy airplane is constantly monitored while tracking the position of the airplane.

Here, if information on the position of the air vehicle appearing as the airspace can not be obtained, the sensing operation of the air vehicle is continuously performed until the position information of the corresponding air vehicle is acquired.

Then, the target is set as the target, and the information about the size, type, position, flight path, etc. of the flight body is set.

Then, it monitors the flight body to the interceptor capable of intercepting the flight body, and inputs the information about the position and flight path of the acquired body.

Here, it is obvious that an antenna generally used at present is used to monitor a flying object, and a detailed description thereof will be omitted.

In addition, the interceptor capable of intercepting the air vehicle can be adjusted by the ground control unit by radio, and is similar to the currently used unmanned airplane, and a detailed description thereof will be omitted.

In addition, hooks (not shown in the drawing) or nets (not shown in the figure) may be formed in the body, so that the body may come into contact with the flying body and come into physical contact with the flying body. Or both of them can be installed, and the detailed description will be omitted.

The shape of the hooks and the net may be any generally used at present.

Further, the positions of the hooks provided on the body can be set at various positions depending on the purpose of the user, such as the upper side and the lower side of the body cavity.

(Not shown) such as a camera that can be set as a target while visually confirming a flight body is installed in the above-mentioned interlocking body.

The image device is generally used in airplanes or helicopters, and a detailed description thereof will be omitted.

It is also recommended that a deployable parachute be installed on the body of the interceptor so that it can be landed safely back in safely.

In addition to this, it is obvious that a communication device (not shown in the figure) capable of performing communication with the ground control unit is installed in the above-mentioned interlocking body, and a detailed description thereof will be omitted.

On the other hand, the ground control unit confirms the enemy airplane as described above, generates information about the enemy airplane, inputs the information to the interlocking body capable of intercepting the airplane, prepares the interlocking body for takeoff, (S20)

In addition, the above-mentioned ground control unit continuously tracks and confirms the position of the flying object, transmits the information to the object, controls the object's flight in the ground control unit while flying the object so that the object is automatically induced by the ground control unit, To the point where it is moving so that the interceptor is close to the aircraft.

Then, when the body of water is approached to the body by the control of the ground control unit as described above, the body of the body is detected through the image device installed in the body, and the corresponding body is set as the target (S30).

When the air vehicle is set as a target by the imaging device installed on the body, the air vehicle body approaches the air vehicle while recognizing the distance to the air vehicle while performing automatic flight, and then, Let's intercept.

In other words, when the object is approached to a certain distance by the control of the ground control unit, the object is detected by the imaging device installed on the object while the object is automatically flying, so that it is detected whether or not the object exists near the object .

Then, when the airplane detects the airplane in the image device, the airplane is set as a target.

In this way, the above-mentioned interlocking body approaches the air vehicle. While the distance between the interlocking body and the air vehicle detected by the image device is continuously checked, the hook provided on the interlocking body approaches the distance enough to be caught by the air vehicle, To intercept and crash.

For example, if the length of hooks on the body is 1m, the hooks on the body should fly within 1m of the body that can be caught on the body, so that the hooks are intercepted by the body.

Here, depending on the position of the hooks provided on the body, the body may approach from the upper part of the body, may approach from the lower body of the body, or may be accessible from the front or rear. do.

When a net is provided in the body, the air is fired up to a distance at which the net can be fired, and then the net is fired to intercept the air body.

Here, the distance at which the net can be fired and the length (spacing, size) of the hooks can be changed or set as desired according to the purpose of the user.

Since the hooks and nets provided on the body are operated only within a certain radius, it is possible to perform the interception when the body is in the closest position to the body of the airplane, so that the interception rate can be increased. It is possible to intercept while pulling directly, and it is possible to minimize the damage of civilians and the like by crashing the flight body to a certain point.

As described above, the interceptor that takes off to intercept the airplane sets and tracks only the airplane accurately through the image device, so that it is possible to reduce the damage of the interrogator by the erroneous target setting and other damage by the interjector, It is possible to increase the interception rate to the air vehicle.

Meanwhile, when a flying object is detected in the imaging device installed in the body, and the corresponding object is set as a target as described above, the object is intercepted in the manner described above, and the object is approached to the object and the object is detected through the image device When the aircraft is not detected, the ground control unit tracks the position of the flying object that grasps the position in real time, and controls so that the guided object is automatically guided to approach the flying object.

If an air vehicle is detected in the imaging apparatus installed in the body, the air vehicle is intercepted in the manner described above. If the air vehicle is not detected in the imaging apparatus installed in the body, the ground control unit directly controls the body And it is repeated until the imaging device of the interceptor detects the object as a target.

Meanwhile, when the interceptor is taken off and approaches the air vehicle, the interceptor may be intercepted at a time when the interceptor is performed. However, if the interceptor fails, the interceptor may re-execute the interceptor for the corresponding air vehicle . (S35)

In other words, after detecting a flight object in the ground control department, when the interceptor fails by attempting to intercept the interceptor to take off the interceptor to intercept the interceptor, the interceptor is controlled again by the ground control section, And to perform the interception again as described above.

Then, when the interceptor is failed completely by attempting the interception for one to three times, the interceptor is returned to return.

Here, the reason why the interceptor is intercepted only a certain number of times is that the fuel used in the interceptor is limited, so the interceptor attempts only a certain number of times according to the distance of the interceptor.

In addition, although the interceptor may be re-executed by causing the interceptor to fly several times in accordance with the purpose of the user so that the interceptor fails to intercept the intercepted air several times as described above, the interceptor may be re-executed.

In this case, if the net is installed in the body of the agent, it is difficult to collect the net again, so that the body may attempt to intercept only once. If the net is installed, the interception may be attempted several times .

It is also intended to enable the interceptor to carry out the intercept while constantly tracking the target's aircraft, thereby increasing the intercept rate.

Meanwhile, when the air vehicle is intercepted by intercepting the airplane at a time or intercepting the airplane several times as described above, it is possible to safely land the airplane using the parachute installed on the interlocking body, while returning the corresponding interlocking body to the point designated by the ground control unit.

As a result, the relevant interceptor can be safely landed and reused.

Here, the parachute mounted on the interlocking body is generally used in an unmanned airplane, and a detailed description such as an installation state and an operating state is omitted.

If one interceptor attempts at least one to four or five attempts to intercept an airplane, if the intercept fails, the interceptor is controlled by the ground control unit to safely land using the parachute installed on the interceptor, (S40), the airplane is intercepted and the airplane is intercepted after resetting and inputting the position information of the airplane to be intercepted as described above in the interlocking body.

Also, even if one interceptor fails one interception, re-interception may be performed once or three times. In this case, even if the intercept fails completely, a new interceptor is searched to re-execute interception to the interceptor to increase the intercept rate There are advantages to be able to.

As described above, it is possible to prevent the damage caused by the air vehicle by increasing the interception rate for the air vehicle.

Although the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious to those who have knowledge of.
