Description

Spatial information-based airspace and howitzer ballistic collision threat analysis device and method}

The present invention relates to a spatial information-based airspace and howitzer ballistic collision threat analysis apparatus and method. It relates to an apparatus and method for analyzing airspace and howitzer ballistic collision threats based on geospatial information, which can guarantee the safety of allied aircraft from artillery firepower as well as possible.

In general, in a wartime situation, numerous aircraft are active in the air.

Aviation vehicles include tactical air force such as bombers, fighters, transport aircraft, surveillance and reconnaissance aircraft, including civil aircraft, helicopter types of army aviation such as maneuver helicopters, attack helicopters, medical helicopters, surveillance and reconnaissance helicopters, command aircraft, ballistic missiles, and cruise missiles. Missiles and shells fired from artillery firearms numbering in the tens of millions fly through the air.

Referring to FIG. 1, under this circumstance, regulations are established to ensure the safe flight of friendly aircraft such as tactical air force and army helicopters through the method of airspace control means from the trajectory of hundreds of thousands of howitzers that are invisible to the naked eye. It controls the artificial airspace.

Therefore, from the point of view of an artillery unit conducting artillery fire on various targets in real time, technology that automatically analyzes and processes airspace and howitzer ballistic collision threats is very important because airspace control limits artillery fire. In other words, artillery fire that does not interfere with controlled airspace is very necessary for mission performance.

To this end, when artillery fire is to be conducted, it must be possible to quickly and accurately determine whether or not an artillery shell collides with the planned airspace control means, and if the shell passes through the airspace control means, the degree of threat is analyzed probabilistically to obtain quantitative information. By providing this, it is possible to make a more rational decision on whether or not to conduct artillery fire.

Referring to FIG. 2, the shell is fired from the muzzle and passes as much as the range while drawing a parabola in the air.

While the shell is flying in the target area, the latitude, longitude, and altitude of the shell and the latitude, longitude, and altitude of the area set as an airspace control method are compared and analyzed to determine the location of the shell and the latitude and longitude of the airspace within the airspace area. , If the altitude value is the same, it is determined that the artillery ballistics collide with the airspace.

In the case of shell collision with airspace, artillery fire should not be conducted for the safety of friendly aircraft.

However, in the prior art, it is impossible to identify the state in which the shells fly in a parabolic line with the naked eye, and since the installed airspace is also designated only by numerical values of latitude, longitude, and altitude, there are many problems in determining whether the artillery trajectory collides with the airspace. difficulties exist.

In particular, airspace control means installed for the purpose of control and cooperation to ensure the safety of air power such as fighter jets, helicopters, and unmanned aerial vehicles operated in the air from hundreds of thousands of shells fired from thousands of artillery pieces in wartime Therefore, it may be a limitation that the artillery firepower of the ground forces cannot be effectively operated.

This diagram shows an example of collision probability analysis between airspace and howitzer trajectories of several shots in the spatial information-based airspace and howitzer ballistic collision threat analysis device according to the method.

Referring to FIG. 4 , first, at least one fire request terminal 200 identifies a target (S310) and transmits fire request information including target information (S320). If necessary, target information may be received through a separate input unit instead of the shooting request terminal 200 .

Then, the information receiver 120 receives target information from the shoot request terminal 200, and the controller 130 displays the location of the target on a map using the target information from the shoot request terminal 200 ( S410). Referring to FIGS. 5A and 5B , airspace, d-marks, and d-marks are displayed in a plan view and a side view. There are two targets here, but there can be only one target, or more.

Next, the control unit 130 calculates the range from the firing unit to the target in units of 10m and plots the firing line on the plan view (S420). Here, the firing line may be an artillery ballistic. 5A and 5B, when calculating the range from the shooting unit to the target in units of 10 m and drawing a firing line, the range calculation is necessary to draw a trajectory (ballistic curve) through which the shell passes, and can be calculated with a trigonometric function. can

Next, the controller 130 performs a collision test between the airspace control means and the artillery ballistics (S430).

This process is explained in more detail.

Referring to FIG. 6 , the controller 130 determines whether a collision occurs at the trajectory 1 position (S431).

Here, referring to FIG. 7 , it is determined whether a collision occurs in each section by dividing the line of fire, that is, the entire section of the artillery ballistic trajectory into n sections.

If a collision occurs in the trajectory 1 section, the controller 130 displays the collision section in red (S436).

Then, the controller 130 determines whether a collision occurs at the trajectory 2 position (S432).

If a collision occurs in the trajectory 2 section, the controller 130 displays the collision section in red (S436).

Then, the control unit 130 determines whether a collision occurs at the trajectory 3 position (S433).

If a collision occurs in the trajectory 3 section, the controller 130 displays the collision section in red (S436).

Then, the control unit 130 determines whether a collision occurs at the trajectory 4 position (S434).

If a collision occurs in the trajectory 4 section, the controller 130 displays the collision section in red (S436).

Then, the control unit 130 determines whether a collision occurs at the trajectory 5 position (S435).

If a collision occurs in the trajectory 5 section, the controller 130 displays the collision section in red (S436).

After that, the above process is repeated up to the trajectory n.

Finally, the control unit 130 displays the collision section in red and the non-collision section in white. Referring to FIG. 7 , only the collision occurrence section is displayed in red, and the remaining sections are displayed in white. Therefore, the user can easily check the collision section and its size with the naked eye.

Also, referring to FIG. 8 , an example of a 3D simulation to which the collision detection technique is applied is illustrated. Here, the front is the view of the artillery trajectory and the airspace control means in terms of longitude and altitude, the plane is the picture considering only longitude and latitude, and the side is the picture showing the simulated result in terms of latitude and altitude.

Referring to FIG. 8 , by applying collision detection technology to airspace information and target information stored in the storage unit 110 , collision detection results may be simultaneously analyzed in three dimensions and displayed on a screen.

In addition, referring to FIG. 9, the trajectory of a shell launched from the muzzle and passing to the target is managed as spatial information (X, Y, Z values), and the airspace information is also managed as spatial information (X, Y, Z values) If the spatial information value of the shell and the spatial information value of the airspace match (collision occurs), it is displayed in red.

At this time, the ballistic trajectory of the shell is the highest trajectory for each distance specified in the shooting specification table for each caliber, and the specifications are stored and managed in the storage unit 110, and when the range to the target is determined, a ballistic curve is automatically generated and spatial information (latitude, longitude , altitude) values can be calculated.

If necessary, the control unit 130 can display the ballistic trajectory and airspace of the shell in various ways.

Next, after the collision test, the control unit 130 determines whether a collision occurs (S440). Here, referring to FIG. 10, there are three types of airspace control means for controlling airspace, such as a cylindrical shape, a regular hexahedron shape, or a corridor shape. Considering the flight characteristics of aircraft, since flight forms such as vertical descent, vertical ascent, and left/right right angle rotation are practically impossible, artillery ballistics that pass through these airspace points within the airspace zone will collide with aircraft operating within the airspace. do not pose a threat Therefore, there is a need for a technical alternative that can maximize the safety of aircraft operating in the airspace control zone while efficiently operating the available artillery power means. Basically, the risk analysis analyzes that the closer the center point of the airspace control means and the longer the analyzed collision distance, the greater the risk of collision.

If no collision occurs, the control unit 130 issues a shooting command (S450). 5A and 5B, when the artillery trajectory does not collide with the airspace control means, as in the case of a temporary target, the controller 130 issues a shooting command to the fire control device 320 of the firing unit 310 to fire. do. Then, according to the decision of the operator of the operator terminal 330, the shooting unit 310 finally shoots (S510).

Meanwhile, when a collision occurs, the controller 130 calculates a collision probability (S460). 5a and 5b, as a result of the collision test, in the case of a target, a collision with the airspace occurs because the trajectory of the shell passes through the airspace area space, and additional judgment (decision) is required on whether to fire. Calculate the collision probability.

Assuming that a collision is expected in m intervals in n intervals of all artillery bullets, the collision probability may be expressed as a percentage obtained by multiplying m by n and multiplied by 100, or simply expressed as m/n.

Then, the controller 130 determines whether the collision probability is at a risk level (S470). That is, when an airspace collision occurs, a fire command is issued based on a specific standard set by the user, the mission is stopped, or one of the two is selected. These specific criteria may be set in advance and the control unit 130 may automatically refer to them, or the user may determine them if necessary.

As a result of the determination in the step (S470), if the collision probability is at a risk level, the control unit 130 may issue a shooting command (S450). Then, the shooting unit operator can shoot by adjusting the shooting control device 320 (S510). If necessary, the shooting control device 320 may shoot directly according to the target information (S510).

For example, if an airspace collision occurs but the probability of a collision between a shell and an aircraft is extremely low, information necessary for decision-making is provided so that shooting can be carried out.

Referring to FIG. 11, when a shooting unit A, a shooting unit B, and a shooting unit C want to shoot at a target or a target company, all artillery ballistics collide with airspace, so shooting is conducted against any target according to airspace control regulations. Shouldn't be.

However, in wartime, in this situation, critical limitations can occur in the operation of artillery firepower by losing the firing timing for important targets that threaten the friendly forces.

Therefore, in the event of a collision between the artillery ballistics and airspace means, the level of risk is probabilistically presented, so that the firing unit can accept the risk to a certain extent according to the importance of the target and automatically provide information necessary for decision-making to determine whether to fire or not. do.

For example, in the case of FIG. 11, even though bare targets, multi-targets, bar targets, and dead targets collide with airspace, the risk (probability) of collision is extremely low, so artillery fire can be fired if necessary according to the importance of the target.

Depending on the importance of the target, if necessary, the probability of collision with which shooting is possible may be set differently.

For example, in the case of a first-class important target, the probability of collision is less than 20%, in the case of a second-class target, the probability of collision is less than 10%, and in the case of a third-class target, the probability of collision is 5 You can also make it shoot below %.

On the other hand, if the probability of collision is not at a risk level, the control unit 130 stops shooting (S480). In other words, the shooting mission is stopped.

In the above embodiment of the present invention, by accurately calculating the airspace and howitzer ballistic collision threat and providing it to the user, not only can the artillery power possessed by the military be effectively used in wartime, but also the safety of friendly aircraft from artillery fire can be guaranteed. .

In addition, in the embodiment of the present invention, it is possible to provide conditions for maximizing the use of ground artillery firepower while achieving the purpose of airspace control when using space information-based airspace and howitzer ballistic collision threat analysis technology.

In addition, in the embodiment of the present invention, it is possible to effectively and properly attack a ground target that is a threat from the standpoint of a maneuver force engaging in close combat with the enemy without losing strike timing, thereby ultimately increasing the power management effectiveness index.
