  The present invention relates to a shooting effect determination program, a shooting effect determination device, and a shooting effect determination method, and more particularly to a shooting effect determination program, a shooting effect determination device, and a shooting effect determination method for determining a shooting effect on a target.

  For example, in simulation training systems for shooting training and amusement facilities for shooting games, the reality of shooting training and shooting games is enhanced by using a shooting effect determination device that can determine the effect of shooting performed virtually. ing. Here, an example of a simulation training system using a music firearm will be described. In addition, a mortar and a howitzer can be raised as a music firearm used for shooting training.

  In addition, for example, a simulation training system using a music firearm includes a simulation training device for actual training performed by the Self-Defense Forces and the police, a simulator for setting various situations on a computer, and performing situation judgment and command control training. .

  In the simulated training system, instead of firing the actual bullets, shooting specification information is input, and the burst point of the bullet is calculated based on the shooting specification information. The simulated training system determines the degree of wear of the target based on the calculated position coordinates of the burst point and the target position coordinates, and notifies the wireless device etc. held by the target to display the situation. .

  In the conventional simulation training system, the wear range is calculated based on the burst point and target position coordinates of the simulated shooting, but the wear range due to the actual bullet (actual bullet) burst and the probability of occurrence of wear in that wear range Could not be calculated accurately for the following reason.

  The range of wear due to actual bullets is caused by the scattering of fragments due to the bursting of bullets. The pattern of fragment scattering varies depending on the type of bullet (for example, the shape of a bullet). In a general bullet, debris scatters in the direction of 60 to 100 degrees from the bullet traveling direction (bullet direction). For this reason, the range of wear due to actual bullets tends to be a butterfly shape with the bullet drop direction (fall direction) as the axis.

  In the conventional simulation training system, the wear range is calculated from the burst point of the simulated shooting, the position coordinates of the target, the type of the curved firearm, and the type of the bullet, so refer to the distance between the burst point and the target and The wear range corresponding to the type and type of bullet is only calculated, and the wear range and the probability of occurrence of wear by an actual bullet cannot be accurately simulated. For this reason, the conventional simulation training system has a problem that it is impossible to accurately determine the effect of the shooting by the music firearm.

Next, the central station 11 calculates the wear range due to the simulated shooting and the wear occurrence probability in the wear range as described later.

  Based on the received position information of the target 52, the central office 11 searches for the target 52 existing within the wear range, and extracts the target 52 to be worn by the wear occurrence probability in the wear range.

In addition, in the simulation training system 10 of FIG. 5, the central station 11, the radio unit 12 for the firearm and the radio unit 13 for the target can be integrated, and the simulation can be performed by one computer and used for command and control training. It is.

  FIG. 6 is a flowchart showing the processing procedure of the central station in which the shooting effect determination program is implemented. FIG. 7 is an image diagram showing the relationship between the bullet burst point and the mesh. The central station 11 proceeds to step S1, and calculates the trajectory 53 of the simulated shooting by the trajectory calculation. The central office 11 refers to the position, direction, elevation, angle of the firearm, the type of bullet, the mass of the bullet, etc. obtained as the shooting specification information, and the trajectory 53 by a physical formula such as a parabola type or a modified mass ballistic. calculate.

  In order to omit the calculation, the central station 11 may obtain the position coordinates of the rupture point 54 as the shooting specification information. When the position coordinates of the rupture point 54 are obtained, the central office 11 sets the direction connecting the position coordinates of the firearm 51 and the position coordinates of the rupture point 54 as the drop direction (fall direction), and the drop angle of the bullet 70 at the rupture point 54. A numerical value registered in advance is used.

  In step S2, the central station 11 calculates a ballistic vector 71. Here, the central station 11 calculates a ballistic vector 71 as a three-dimensional vector from the trajectory 53 calculated in step S1, for example. Proceeding to step S3, the central station 11 calculates a rupture point 54. Here, the three-dimensional coordinates of the rupture point 54 are calculated from the rupture altitude obtained by the central station 11 as shooting specification information and the trajectory 53 calculated in step S1.

  In step S4, the central office 11 calculates a distance R73 from the rupture point 54 for each mesh position 72. Here, the three-dimensional distance from the rupture point 54 is calculated for each mesh position 72 based on the three-dimensional coordinates of the rupture point 54 calculated by the central office 11 in step S3 and the three-dimensional coordinates of the target mesh position 72.

  In step S5, the central office 11 calculates a vector 75 connecting the rupture point 54 and the mesh position 72. Here, based on the three-dimensional coordinates of the rupture point 54 calculated in step S3 and the three-dimensional coordinates of the target mesh position 72, the central office 11 sets a vector 75 connecting the rupture point 54 and the mesh position 72 as a three-dimensional vector. calculate.

  Proceeding to step S6, the central office 11 calculates the angle θ74 from the bullet (warhead) based on the ballistic vector 71 calculated in step S2 and the vector 75 connecting the rupture point 54 and the mesh position 72.

  Proceeding to step S7, the central office 11 refers to the scattered fragment number table shown in FIG. 8, and acquires the scattered fragment number N based on the angle θ74 from the bullet calculated in step S6. FIG. 8 is a configuration diagram of an example of the scattered fragment number table. By setting the scattered fragment count table for each type of bullet, the wear range can be determined more accurately.

  In the scattered fragment number table of FIG. 8, the number N of scattered fragments corresponding to the angle θ74 from the bullet is set from 0 degrees to 180 degrees in units of 5 degrees. The scattered fragment number table in FIG. 8 is shown in FIG. 9 as a graph. FIG. 9 is a graph created from the scattered fragment number table. FIG. 10 is a schematic diagram showing the angle θ from the bullet. The angle θ = 0 degrees from the bullet is the traveling direction of the bullet 70. The angle θ = 180 degrees from the bullet is in the direction opposite to the direction of travel of the bullet 70.

  Proceeding to step S8, the central office 11 calculates a fragment hit rate for each mesh from the following equation (1) based on the number N of scattered fragments acquired in step S7 and the distance R73 from the burst point 54. In the following formula (1), the greater the number N of scattered fragments and the shorter the distance R from the rupture point 54, the higher the fragment hit rate.

なお、ステップＳ４〜Ｓ８までの処理は対象となるメッシュ毎に行われる。対象となるメッシュの範囲（対象範囲）は、例えば弾丸７０の効果範囲を考慮して、破裂点５４から半径１５０ｍ程度とする。メッシュの大きさを５ｍ×５ｍとし、３００ｍ×３００ｍの４角形を対象範囲とした場合、対象となるメッシュの数は３６００となる。このように損耗範囲をメッシュにより管理することで、中央局１１は損耗範囲内に存在する目標５２の検索が容易となり、コンピュータの処理負担が軽減される。

In addition, the process from step S4 to S8 is performed for each target mesh. The target mesh range (target range) is set to a radius of about 150 m from the rupture point 54 in consideration of the effect range of the bullet 70, for example. When the mesh size is 5 m × 5 m and a 300 m × 300 m square is the target range, the number of target meshes is 3600. By managing the wear range with the mesh in this way, the central office 11 can easily search for the target 52 existing within the wear range, and the processing load on the computer is reduced.

  Furthermore, the central office 11 corrects the fragment hit accuracy in consideration of the posture (standing posture, intermediate posture, lying posture) of the target 52, and sets the hit portion (head, trunk, arms, legs) as follows. Judge as follows.

  FIG. 11 is a flowchart showing the processing procedure of the central office for correcting the fragment hit rate according to the posture and determining the hit part. FIG. 12 is an image diagram showing the relationship between the bullet burst point and the target elevation angle α.

  In step S11, the central station 11 calculates the elevation angle α121 of the rupture point 54 and the target 52 based on the rupture point 54 and the mesh position 72. Proceeding to step S12, the central office 11 acquires the correction value of the hit rate according to the posture of the target 52 and the rupture point 54 and the elevation angle α121 of the target 52 from the correction table shown in FIG. 13, and corrects the fragment hit rate.

  FIG. 13 is a configuration diagram of an example of a correction table of fragment hit accuracy by a target posture. In the correction table of FIG. 13, the correction value of the hit rate according to the posture of the target 52 (standing posture, intermediate posture, prone posture) and the burst point 54 divided into three stages every 30 degrees and the elevation angle α121 of the target 52 Is set.

  By multiplying the correction value acquired from the correction table of FIG. 13 by the fragment hit rate calculated by the equation (1), the central station 11 is in accordance with the posture of the target 52 and the elevation angle α 121 of the burst point 54 and the target 52. You can correct the hit accuracy.

  The correction table of FIG. 13 is set in consideration of the area ratio of the target 52 viewed from the burst point 54. FIG. 14 is an image diagram showing an example of the target posture and the relationship between the burst point and the target elevation angle α. FIG. 14A shows an example of a standing posture. FIG. 14B shows an example of the intermediate posture. FIG. 14C shows an example of a lying posture.

  In the standing posture, as the elevation angle α between the rupture point 54 and the target 52 is smaller, the fragment accuracy rate is higher, and as the elevation angle α between the rupture point 54 and the target 52 is larger, the fragment accuracy rate is lower. When the fragment hit accuracy is in the prone posture, the smaller the elevation angle α between the burst point 54 and the target 52 is, the lower the fragment hit rate is. The larger the elevation angle α between the burst point 54 and the target 52 is, the higher the fragment hit rate is. The fragment hit rate is not affected by the elevation angle α of the burst point 54 and the target 52 in the intermediate posture, and the fragment hit rate becomes normal.

  In step S13, the central office 11 acquires the hit probability of each part according to the posture of the target 52 and the rupture point 54 and the elevation angle α121 of the target 52 from the hit part determination table shown in FIG. , Torso, arms, legs).

  FIG. 15 is a configuration diagram of an example of a hit location determination table based on a target posture. In the hit part determination table of FIG. 15, the position of the target 52 according to the posture of the target 52 (standing posture, intermediate posture, prone posture) and the burst point 54 divided into three stages every 30 degrees and the elevation angle α 121 of the target 52. Probability is set.

  Based on the probability of the hit part acquired from the hit part determination table of FIG. 15, the central station 11 can determine the hit part according to the posture of the target 52 and the elevation point α 121 of the burst point 54 and the target 52. The hit site determination table of FIG. 15 is set in consideration of the area ratio of each site of the target 52 as viewed from the rupture point 54.

  By performing the processing shown in FIGS. 6 and 11, the central office 11 can create a distribution diagram representing the wear range and the wear occurrence probability as shown in FIGS. FIG. 16 is a distribution diagram of an example showing a bullet drop angle of 60 degrees, a wear range at the time of ground rupture, and a wear occurrence probability. The surface rupture has a rupture altitude of 0 m. FIG. 17 is a distribution diagram showing an example of a wear range and a wear occurrence probability when the bullet drop angle is 60 degrees and the burst height is 10 m.

  In the distribution diagram of FIG. 16, since the elevation angle α between the rupture point 54 and the target 52 is small, the fragment hit rate of the standing posture is high. In the distribution diagram of FIG. 17, since the elevation angle α between the rupture point 54 and the target 52 is large, the fragment hit rate of the prone posture is high.

  Further, the central station 11 corrects the wear range by taking into account whether there is an obstacle 181 between the target 52 and the rupture point 54 by looking through. FIG. 18 is an image diagram illustrating an example of visual inspection from a rupture point to a mesh.

  The central office 11 stores altitude information for each mesh. Based on the altitude information of each mesh, the central office 11 performs visual inspection from the rupture point 54 to each mesh as follows. First, the central station 11 calculates a three-dimensional line segment 183 connecting the rupture point 54 and the corresponding mesh 182. The central office 11 extracts a mesh through which the line segment 183 passes on a two-dimensional plane.

  The central office 11 compares the altitude component of the line segment 183 with the altitude component of the extracted mesh, and determines whether there is a location where the altitude component of the line segment 183 is lower than the extracted altitude component of the mesh. . When there is a portion where the altitude component of the line segment 183 is lower than the extracted altitude component, the central office 11 determines that the corresponding mesh 182 cannot be seen and excludes the corresponding mesh 182 from the wear range.

  In the case of FIG. 18, the obstacle 181 exists between the rupture point 54 and the corresponding mesh 182, and the altitude component of the mesh constituting the obstacle 181 is higher than the altitude component of the line segment 183. 182 is excluded from the wear range.

  The central office 11 can create a distribution diagram representing the wear range and the wear occurrence probability as shown in FIG. FIG. 19 is a distribution diagram showing an example of a bullet fall angle of 30 degrees, ground burst, wear range when there is an obstacle, and wear occurrence probability. In the distribution diagram of FIG. 19, the rear side of the obstacle 181 as seen from the bursting point is excluded from the wear range.

  Further, the central station 11 can calculate the degree of wear in consideration of the weight of the fragments. FIG. 20 is a configuration diagram of an example of a fragment weight distribution table. In the fragment weight distribution table of FIG. 20, the fragment weight is defined by being divided into three sections. When calculating the degree of wear for the target 52 to be worn, the central office 11 uses the piece weight distribution table in FIG. The degree can be calculated. In general, the heavier the debris, the greater the degree of wear. By defining the fragment weight distribution table for each type of bullet 70, the central station 11 can more accurately determine the degree of wear.

  Thus, in the simulated training system 10 according to the present invention, the posture of the target 52 is calculated by calculating the wear occurrence probability with the correction value corresponding to the posture of the target 52 registered in advance and the rupture point 54 and the elevation angle 121 of the target 52. It is possible to calculate the probability of wear taking into consideration. Further, in the simulation training system 10 according to the present invention, the calculation of the wear occurrence probability in consideration of the altitude (rupture altitude) of the rupture point 54 is realized.

  In the simulated training system 10 according to the present invention, wear is generated by determining the hit part with the pre-registered posture of the target 52 and the hit probability of each part according to the rupture point 54 and the elevation angle 121 of the target 52. Accurately determine the hit location.

  In the simulation training system 10 according to the present invention, it is possible to make a visual inspection from the rupture point 54 to each mesh based on altitude information of each mesh registered in advance, and to reflect the influence of the obstacle 181 in the wear range. it can.

  Further, in the simulated training system 10 according to the present invention, paying attention to the fact that the degree of wear tends to change according to the weight of the hit piece, the degree of wear is determined by using a pre-registered piece weight distribution table. Can be determined by approximating the actual battle.

(Summary)

Accordingly, by using the simulation training system 10 and the simulation, more effective actual training and command and control training are possible.

  In addition, the shooting effect determination program according to the present invention manages the wear range with a mesh, thereby facilitating the extraction of the target 52 existing in the wear range and simplifying the process.
