Description

Technology Field

[0001] The present invention relates to a method and apparatus for diagramming no-fire zones on an air defense map of an anti-aircraft gun. Background Technology

[0002] Anti-aircraft guns are air defense artillery weapons designed to fire at aerial targets; representative examples include self-propelled anti-aircraft guns mounted on vehicles or armored vehicles, which add mobility.

[0003] In such anti-aircraft guns, a no-fire zone is required to restrict firing in certain cases to protect civilian homes or friendly forces; typically, this no-fire zone is established as a range of elevation angles prohibiting firing for each azimuth. The gunner must clearly recognize the established no-fire zone and operate the gun accordingly.

[0004] The no-fire zone consists of azimuth and elevation angle information, so it corresponds to three-dimensional information. However, since the computer screen used for operating the anti-aircraft gun is two-dimensional, there are limitations in representing three-dimensional no-fire zone information, which makes it difficult for the gunner to clearly recognize the no-fire zone. The problem to be solved

[0005] The technical problem to be solved by the present invention is to provide a method and apparatus for graphically representing a no-fire zone on an air defense map of an anti-aircraft gun, which enables a gunner to clearly recognize the no-fire zone by graphically representing azimuth and elevation angle information constituting the no-fire zone on a computer screen for operating the anti-aircraft gun.

[0008] The above-mentioned conversion step can convert the firing prohibition elevation angle of the above-mentioned firing prohibition elevation angle range into a radius proportional to the corresponding firing prohibition elevation angle.

[0009] The above-mentioned conversion step can convert the firing prohibition elevation angle of the above-mentioned firing prohibition elevation angle range into a radius that is non-linearly proportional to the corresponding firing prohibition elevation angle by an order greater than 1.

[0010] The above conversion step can convert the above firing prohibition elevation angle into a radius using the following mathematical formula.

[0011]

[0012] (Here, is the radius above, R is the maximum radius, represents the above-mentioned firing prohibition elevation angle, and is a constant greater than 1)

[0013] The above method for visualizing a no-fire zone further includes the step of receiving the current azimuth and current elevation angle of a gun, and in the visualizing step, depending on whether the current elevation angle falls within the range of no-fire elevation angles corresponding to the current azimuth angle, the no-fire zone may be displayed by overlapping with different transparency on the air defense map.

[0014] The step of diagramming the no-fire zone may include: determining transparency based on whether the current elevation angle falls within the no-fire elevation angle range for the current azimuth angle; and displaying the no-fire zone on the air defense map by overlapping it with the determined transparency.

[0015] The step of determining the transparency is to determine the first transparency if the current elevation angle falls within the range of prohibited elevation angles for firing with respect to the current azimuth angle, and to determine the second transparency if the current elevation angle does not fall within the range of prohibited elevation angles for firing with respect to the current azimuth angle, and the first transparency may be lower than the second transparency.

[0016] The step of determining the transparency above can determine the transparency according to the following mathematical formula.

[0017]

[0018] (Here, is the above current elevation angle, The transparency to be determined above, The above-mentioned first transparency, The above second transparency, and Each represents the lower and upper limits of the firing prohibition elevation angle range for the above current azimuth, and is a predetermined value)

[0019] A computer program according to the present invention for solving the above technical problem is stored on a computer-readable storage medium and executes a method for drawing a no-fire zone on an air defense map of the above-described anti-aircraft gun on a computer.

[0020] An apparatus for plotting a no-fire zone on an air defense map of an anti-aircraft gun according to the present invention for solving the above technical problem comprises: a memory storing one or more programs for plotting a no-fire zone on an air defense map of an anti-aircraft gun; and one or more processors performing an operation for plotting a no-fire zone on an air defense map of an anti-aircraft gun according to the one or more programs stored in the memory, wherein the processor receives a no-fire elevation angle range for each azimuth angle, converts the no-fire elevation angle range for each azimuth angle into a radius range for each azimuth angle, and plots a no-fire zone on an air defense map according to the radius range for each azimuth angle, wherein the no-fire zone is displayed overlaid on the air defense map with a predetermined transparency.

[0021] The above processor can convert the firing prohibition elevation angle of the firing prohibition elevation angle range into a radius proportional to the corresponding firing prohibition elevation angle.

[0022] The processor can convert the firing prohibition elevation angle of the firing prohibition elevation angle range into a radius that is non-linearly proportional to the corresponding firing prohibition elevation angle by an order greater than 1.

[0023] The processor further receives the current azimuth and current elevation angle of the gun, and the processor can display the no-firing zone on the air defense map by overlapping it with different transparency levels depending on whether the current elevation angle falls within the no-firing elevation angle range for the current azimuth angle.

[0024] The processor determines transparency based on whether the current elevation angle falls within the range of no-fire elevation angles for the current azimuth angle, and can display the no-fire zone by overlapping it on the air defense map with the determined transparency.

[0025] The processor determines a first transparency if the current elevation angle falls within the range of prohibited elevation angles for the current azimuth angle, and determines a second transparency if the current elevation angle does not fall within the range of prohibited elevation angles for the current azimuth angle, and the first transparency may be lower than the second transparency.

[0030] FIG. 1 shows a block diagram of a device for diagramming a no-fire zone on an air defense map of an anti-aircraft gun according to one embodiment of the present invention.

[0031] The firing prohibition zone diagramming device (100) may be mounted on an anti-aircraft gun system or a computer system for operating the anti-aircraft gun. The firing prohibition zone diagramming device (100) diagrams a firing prohibition zone on the air defense map of the anti-aircraft gun. The air defense map around the anti-aircraft gun and the range of firing prohibition elevation angles by preset azimuth angle may be stored in memory, etc., or input into the firing prohibition zone diagramming device (100) via a wired / wireless network.

[0032] The no-fire zone diagramming device (100) may include one or more processors (110), a computer-readable storage medium (130), and a communication bus (150).

[0033] The processor (110) can control the operation of the no-fire zone diagramming device (100). For example, the processor (110) can execute one or more programs (131) stored in a computer-readable storage medium (130). One or more programs (131) may include one or more computer-executable instructions, and the computer-executable instructions may be configured to cause the no-fire zone diagramming device (100) to perform an operation to diagram a no-fire zone on an anti-aircraft gun's air defense map when executed on the processor (110).

[0034] A computer-readable storage medium (130) is configured to store computer-executable instructions or program code, program data and / or other suitable forms of information for plotting no-fire zones on an air defense map of an anti-aircraft gun. A program (131) stored in the computer-readable storage medium (130) includes a set of instructions executable by a processor (110). In one embodiment, the computer-readable storage medium (130) may be memory (volatile memory such as random access memory, non-volatile memory, or a suitable combination thereof), one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, other forms of storage media that are accessed by the no-fire zone plotting device (100) and can store desired information, or a suitable combination thereof.

[0035] The communication bus (150) interconnects various other components of the no-fire zone diagramming device (100), including the processor (110) and the computer-readable storage medium (130).

[0036] The no-fire zone diagramming device (100) may also include one or more input / output interfaces (170) and one or more communication interfaces (190) that provide interfaces for one or more input / output devices. The input / output interfaces (170) and the communication interfaces (190) are connected to a communication bus (150). An input / output device (not shown) may be connected to other components of the no-fire zone diagramming device (100) through the input / output interface (170).

[0037] FIG. 2 shows a flowchart of a method for diagramming a no-fire zone on an air defense map of an anti-aircraft gun according to one embodiment of the present invention.

[0038] In step S210, the processor (110) receives a pre-set range of elevation angles for firing prohibition by azimuth angle. Azimuth angle The value of 0°≤ It can be ≤360°, and the elevation angle The value of 0°≤ It can be ≤90°. The range of elevation angles prohibiting firing by azimuth is the azimuth not really It can be given as. This is a specific azimuth. at The elevation angle range, i.e., the lower limit of the elevation angle range and upper limit It means that firing is prohibited at the elevation angle between them.

[0039] In step S220, the processor (110) receives the current azimuth and current elevation angles of the gun. The current azimuth and current elevation angles of the gun may be values ​​entered by a user into the anti-aircraft gun system, or values ​​obtained by detecting the turret in the anti-aircraft gun system. In the following, the current azimuth and current elevation angles of the gun are respectively and It is decided to express it as.

[0040] In step S230, the processor (110) converts the range of elevation angles prohibiting firing by azimuth into a radius range by azimuth. This is intended to visualize the range of elevation angles prohibiting firing by azimuth as an area on an air defense map, and the elevation angles prohibiting firing within the range of elevation angles prohibiting firing can be converted into a radius proportional to the corresponding elevation angles prohibiting firing. For example, the range of elevation angles prohibiting firing When given as, the lower limit of the elevation angle range and upper limit Each can be converted into a radius proportional to the corresponding elevation angle.

[0041] The no-fire elevation angle can be converted into a radius using the following mathematical formula.

[0042]

[0043] Here, is the radius, indicates the no-fire elevation angle, and is a constant greater than 1. R is the maximum radius, and the elevation angle It corresponds to the radius when it is 90°.

[0044] is a linear term, and if If θ is 1, the radius increases linearly in proportion to the elevation angle, and Make the radius R when θ is 90°. Exponential This is intended to cause the radius to increase non-linearly with increasing elevation angle, It can be greater than 1. When θ is greater than 1, the no-fire elevation angle is converted into a radius according to the above mathematical formula in such a way that it is non-linearly proportional to the corresponding no-fire elevation angle by an order greater than 1. In other words, at low elevation angles, the radius increases gradually with increasing elevation angle, but as the elevation angle increases, the radius increases rapidly with increasing elevation angle. Typically, no-fire zones are often set low to avoid civilian houses, so it is necessary to carefully avoid the no-fire elevation angle at high elevation angles. Therefore, by ensuring that the no-fire zone expands non-linearly as the elevation angle increases, important information can be conveyed to the shooter more clearly.

[0045] Figure 3 shows a mathematical formula for changing the firing prohibition elevation angle with respect to the radius. The correspondence between the elevation angle and the radius according to the value is shown. Here, the maximum radius R is set to 100 for convenience. Referring to Fig. 3, greater than 1 It can be seen that the radius increases non-linearly with the elevation angle, and It can be seen that the larger θ is, the greater the nonlinearity. That is, The larger the value, the smaller the difference in radius for the same difference in elevation angle appears at low elevation angles, but the larger the difference appears at high elevation angles.

[0046] Figure 4 shows an example of a no-fire zone plotted on an air defense map according to radius ranges by azimuth. This example is the lower limit of the no-fire elevation angle range by azimuth. Assuming it is 0°, therefore, the range of elevation angles prohibiting firing by azimuth is the upper elevation angle It is defined by. As illustrated, the radius range by azimuth (i.e., the upper elevation angle by azimuth). A no-fire zone can be indicated based on the converted radius. For example, if the 12 o'clock direction is defined as 0° azimuth, the upper elevation angle (approx. 49°) for 0° azimuth is converted to 0.48R, the upper elevation angle (approx. 45°) for 90° azimuth (3 o'clock direction) is converted to 0.43R, and the upper elevation angle (90°) for 105° azimuth (7 o'clock direction) is converted to R. By connecting the points of the converted radius for each azimuth, a no-fire zone is displayed that graphically represents the no-fire elevation angle for each azimuth. Referring to Fig. 4, since the radius is set to increase non-linearly with increasing elevation angle, it can be seen that the interval between 30° and 60° is larger than the interval between 0° and 30°, and the interval between 60° and 90° is larger than the interval between 30° and 60°.

[0047] When graphically representing no-fire zones on an air defense map, it may be necessary to enable the gunner to recognize whether the gun's current direction falls within the no-fire zone. To this end, in an embodiment of the present invention, the transparency of the no-fire zone displayed on the air defense map is adjusted to indicate whether the gun's current azimuth and current elevation angles fall within the no-fire zone.

[0048] Referring again to FIG. 2, in step S240, the processor (110) determines whether the current elevation angle falls within the range of the firing prohibition elevation angle for the current azimuth angle.

[0049] If the current elevation angle falls within the range of the no-fire elevation angle for the current azimuth angle, the transparency is determined as the first transparency at step S250, and if the current elevation angle does not fall within the range of the no-fire elevation angle for the current azimuth angle, the transparency is determined as the second transparency at step S260. Here, the first transparency is lower than the second transparency. That is, the first transparency is a relatively low transparency so that the no-fire zone can be displayed darkly, and the second transparency is a relatively high transparency so that the no-fire zone can be displayed faintly.

[0050] In step S270, the processor (110) plots a no-fire zone on the air defense map according to the radius range for each azimuth angle. At this time, the processor (110) displays the no-fire zone on the air defense map by overlapping it with a first or second transparency determined through step S250 or step S260.

[0051] FIG. 5 shows an example in which a no-fire zone is displayed with high transparency (second transparency) on a computer screen for operating an anti-aircraft gun, and FIG. 6 shows an example in which a no-fire zone is displayed with low transparency (first transparency) on a computer screen for operating an anti-aircraft gun.

[0052] Referring to Fig. 5, the current azimuth and current elevation angles of the gun do not fall within the range of elevation angles prohibiting firing at the corresponding azimuth, so the prohibition zone is displayed with high transparency (second transparency). Referring to Fig. 6, the current azimuth and current elevation angles of the gun fall within the range of elevation angles prohibiting firing at the corresponding azimuth, so the prohibition zone is displayed with low transparency (first transparency).

[0053] The first transparency level lowers the transparency of the no-fire zone, causing it to be displayed more intensely. This emphasizes that the no-fire zone is an area where the shooter must exercise caution. The second transparency level increases the transparency of the no-fire zone, causing it to be displayed more faintly. This indicates that the no-fire zone is an area where the shooter needs to exercise less caution, thereby reducing the need for caution for the shooter.

[0054] In this way, displaying the no-fire zone with low transparency when the gun's current direction falls within the no-fire zone and with high transparency otherwise allows the gunner to intuitively know whether the turret's direction is located within the no-fire zone.

[0055] According to an embodiment, a no-fire zone can be displayed with low transparency not only when the current elevation angle of the gun falls within the no-fire elevation angle range but also when it is close to the no-fire elevation angle range. This allows the gunner to intuitively know whether the current direction of the gun falls within or is likely to fall within the no-fire zone. To this end, the transparency of the no-fire zone can be determined according to the following mathematical formula.

[0056]

[0057] Here, is the current elevation angle, The transparency to be determined, is the first transparency, is the second transparency, and Each represents the lower and upper limits of the firing prohibition elevation angle range for the above current azimuth, and is a predetermined value (e.g., 3° ​​to 7°).

[0058] According to the mathematical formula above, transparency is the current elevation angle lower limit of elevation angle see Value as small as that and elevation angle upper limit see If it is between values ​​that are large enough (i.e., if it falls within or is close to the firing prohibition elevation angle range), the transparency is determined as a relatively low first transparency, otherwise the transparency is determined as a relatively high second transparency.

[0059] Therefore, the no-fire zone can be marked in bold not only when the gun's current elevation angle falls within the no-fire elevation angle range, but also when it is close to the no-fire elevation angle range, thereby emphasizing the need for caution to the gunner.

[0060] According to an embodiment of the present invention, the gunner's tactical judgment ability can be improved by graphically representing the no-fire zone of an anti-aircraft gun on a two-dimensional air defense map. In addition, the no-fire zone can be represented more clearly by converting the elevation angle into a radius that is non-linearly proportional. Furthermore, by adjusting the transparency of the no-fire zone based on whether the gun's direction falls within the no-fire zone, the gunner can intuitively recognize the no-fire zone that requires attention.

The device may be implemented using a hardwired device, a field programmable gate array (FPGA), an application-specific integrated circuit (ASIC), etc. Additionally, an interactive recommendation device may be implemented as a system-on-chip (SoC) including one or more processors and controllers.
