Description

  The present invention relates to a shooting effect determination device and a shooting effect determination program, and more particularly to a shooting effect determination device and a shooting effect determination program for determining the effect of a shooting performed virtually.

  For example, in a simulated training system for shooting training and amusement facilities for shooting games, the reality of shooting training and shooting games can be improved by using a shooting effect determination device that can determine the effect of shooting performed virtually. It is increasing. Here, an example of a simulation training system will be described. As firearms used for shooting training, rifles, tanks and the like are raised.

  The simulation training system refers to a system in which a training person holds a laser transmitter that shoots a laser beam that simulates a real bullet and a laser receiver that receives a laser beam struck by another person and performs a shooting training. When receiving a laser beam shot instead of an actual bullet, the shooting effect determination device determines the wear content as a shooting effect based on the intensity and data content of the laser beam.

  FIG. 1 is a configuration diagram of an example of a simulation training system for performing shooting training. The shooting training in the specification of the present application refers to training which is performed by determining the effect of the shooting performed virtually using a radio signal or a laser signal, instead of shooting with an actual bullet.

  The laser transmitter 1 is used by being attached to a firearm that performs shooting training, or simulates the shape of the firearm itself. The laser transmitter 1 transmits a laser beam 3 instead of an actual bullet when a person 2 performs a shooting operation. Rifles and tanks can be raised as the types of firearms used for shooting training.

  Personnels 2 and 7 indicate personnel participating in the shooting training. Here, it is assumed that the person 2 is the shooting side and the person 7 is the shooting side. The laser receiver 4 receives the laser beam 3 transmitted by the laser transmitter 1. The shooting effect determination device 5 is used integrally with the laser receiver 4 or connected to the laser receiver 4. The shooting effect determination device 5 determines the degree of wear with reference to information included in the laser beam 3 and various information stored in the own device.

  The information included in the laser beam 3 includes the type of fired fire, the type of bullet, the shooting time, the position information of the shooting person, and the like. The various types of information stored in the own machine include the type of personnel (people, vehicles, etc.), the posture of the personnel, the location information of the personnel, and the like. A technique for including the shooting time, the position information of the shooter, and the like in the laser beam 3 is described in Patent Document 4, for example.

  The smoke screen 6 shows smoke generated virtually in the training field. Smoke screen 6 is also called smoke cover, and when it encounters an enemy in a battle, or when it strikes, it generates smoke like a curtain by shooting a smoke bomb to block the enemy's field of view. Attached to prevent shooting. In shooting training, no real bullets are shot, so smoke cannot actually be generated.

Although it is possible to generate the smoke screen 6 with a smoke cylinder, there is a problem in that in order to cover the entire training area, it is necessary to arrange the smoke cylinder over the entire training area, which increases costs. In conventional shooting training, training was performed on the assumption that smoke screen 6 was generated. Patent Documents 1 to 4 describe examples of conventional simulation training systems.
Japanese Patent Laid-Open No. 7-146096 Japanese Patent No. 3538870 Japanese Patent No. 2773615 Japanese Patent No. 3427069

  In the conventional simulation training system, training is performed on the assumption that the smoke screen 6 is generated. However, the virtual smoke screen 6 cannot block the view of the person 2 on the shooting side. Since the person 2 can see the person 7 on the shooting side, the person 2 shoots with an aim. Since the person 7 receives the laser beam 3, the person 7 is worn out even if it is assumed that the smoke screen 6 is generated. Thus, the conventional simulation training system has a problem that the effect of generating the smoke screen 6 cannot be reflected in the determination of the shooting effect.

  In addition, the method of generating the smoke screen 6 with the smoke cylinder needs to emit smoke with the smoke cylinder according to the place and time of generation of the smoke screen 6. In order to cover the entire area of the training field, it is necessary to dispose smoke cylinders over the entire area of the training field, which has the problem of increasing costs.

  The present invention has been made in view of the above points, and it is possible to reflect the effect of the smoke screen in the determination of the effect of the virtually performed shooting and the shooting effect without actually generating the smoke screen. An object is to provide a judgment program.

  In order to solve the above-mentioned problem, the present invention is a shooting effect determination device for determining the effect of shooting performed virtually by the shooting side operating the shooting device, the position information of the shooting side that performed the shooting, It is determined whether or not there is a smoke screen generation range between the shooting side and the shot side based on the position information on the shot side hit by the shooting and the smoke screen range information indicating the virtual smoke screen generation range. Further, the present invention is characterized in that a control means for varying the effect of the shooting according to the determination result is provided.

  The present invention is also a shooting effect determination program executed in a computer including at least a storage device and a control device, wherein the storage device stores smoke screen range information representing a virtual smoke screen generation range. The control device, based on the position information on the shooting side that performed the shooting, the position information on the shooting side that was hit by the shooting, and the smoke screen range information that represents the generation range of the virtual smoke screen, It is determined whether or not there is a range of the smoke screen between the shooting side and the step of varying the effect of the shooting according to the determination result, the shooting side operates the shooting device virtually It is characterized by determining the effect of the shooting performed.

  In the present invention, based on the position information on the shooting side where the shooting was performed, the position information on the shooting side hit by the shooting, and the smoke screen range information indicating the generation range of the virtual smoke screen, between the shooting side and the shooting side It is possible to determine whether or not there is a smoke screen generation range, and to vary the shooting effect according to the determination result.

  As described above, according to the present invention, there is provided a shooting effect determination device and a shooting effect determination program capable of reflecting the effect of the smoke screen in the determination of the effect of the virtually performed shooting without actually generating the smoke screen. Is possible.

  Next, the best mode for carrying out the present invention will be described based on the following embodiments with reference to the drawings. The shooting effect determination device 5 of the present invention is used integrally with the laser receiver 4 or connected to the laser receiver 4. The shooting effect determination device 5 assumes that the smoke screen 6 is generated between the shooter and the shot subject even when the smoke screen 6 is not actually generated, and uses the situation to determine the shooting effect. To reflect. By using the shooting effect determination device 5, the effect of the smoke screen 6 can be reflected in the determination of the shooting effect without generating the smoke screen 6 due to a mortar attack or the like in shooting training.

  FIG. 2 is a block diagram of an embodiment of the shooting effect determination apparatus 5. 2 includes a memory 20, a laser light receiving unit 21, a control unit 22, a data receiving unit 23, a position locating unit 24, and a presenting unit 25.

  The memory 20 stores various tables necessary for the processing of the control unit 22. The laser light receiving unit 21 includes a light receiving element for receiving the laser beam 3 transmitted by the laser transmitter 1, and detects the laser beam 3 hitting the body of the personnel 2 and 7 as necessary. Attach to each part of the body of personnel 2 and 7. When receiving the laser beam 3, the laser light receiving unit 21 transmits the bulleted data 26 to the control unit 22. The hit data 26 includes the type of fired fire, the type of bullet, position information on the shooting side, the intensity of the laser signal when the laser beam 3 is received, and the like.

  The data receiving unit 23 receives smoke screen generation information and wind direction / wind speed information from the outside such as a central station (not shown). When the shooting effect determination device 5 is attached to the personnel 2 or 7 or the vehicle, the target to be attached is a moving body, and therefore the shooting effect determination device 5 is a wireless device or the like. When receiving the smoke screen generation information, the data receiving unit 23 transmits smoke screen data 27 to the control unit 22. The data receiving unit 23 transmits the weather data 28 to the control unit 22 when receiving the wind direction and wind speed information.

  As will be described later, the smoke screen data 27 includes two types of cases in which a smoke screen is generated (duration) and a range in which the smoke screen is generated (generation range), and the impact coordinates of the smoke bomb are included. Can be considered.

  The weather data 28 includes the wind direction and wind speed information at the position where the smoke screen is generated. The meteorological data 28 is used when the control unit 22 calculates the diffusion of the generation range of the smoke screen 6 (hereinafter referred to as the smoke screen range) every time.

  The position locator 24 measures the current position of the shooting effect determination device 5 as needed. The position locator 24 is a GPS receiver or the like. The position locator 24 transmits the measured current position as position data 29 to the controller 22. The display unit 25 includes a speaker, an LED, and the like, and displays the degree of wear according to an instruction from the control unit 22. The presenting performed by the presenting unit 25 indicates sound generation by a speaker and light emission by an LED.

  The control unit 22 uses the smoke screen data 27 and weather data 28 received from the data receiving unit 23 and various tables stored in the memory 20 to calculate the smoke screen range for each passage of time, and stores the smoke screen range in the memory 20, for example. When the bullet receiving data 26 is received from the laser light receiving unit 21, the control unit 22 reads the smoke screen range from the memory 20 and refers to the smoke screen range to reflect the effect of the smoke screen 6 in the determination of the shooting effect. The control unit 22 issues a display instruction 30 to the display unit 25 according to the determination result of the shooting effect in order to display the degree of wear.

  Note that the shooting effect determination apparatus 5 of FIG. 2 may be configured without the position locating unit 24 as long as the position data 29 can be received from the outside. Further, the display unit 25 may be configured to be externally connected.

  In the shooting effect determination apparatus 5 of FIG. 2, the shooting effect determination program of the present invention is stored in the memory 20. The control unit 22 reads out the shooting effect determination program stored in the memory 20 and can realize processing as described later according to the shooting effect determination program.

  The shooting effect determination device 5 according to the present invention determines the effect of the virtual shooting that has passed through the smoke screen range and hit the person 7 on the shooting side in the shooting training performed assuming that the smoke screen 6 is generated. This can be different from the determination of the effect of virtual shooting that is shot on the person 7 on the shooting side without passing through the smoke screen range.

  For this reason, in the simulation training system using the shooting effect determination device 5 of the present invention, the field of view of the person 2 on the shooting side cannot be obstructed as in the case of using the conventional shooting effect determination device 5, but the smoke screen is virtually The effect of generating 6 can be reflected in the determination of the shooting effect. Therefore, the shooting effect determination apparatus 5 of the present invention enables shooting training in a form closer to the actual battle environment at a lower cost.

  FIG. 3 is a flowchart of an embodiment showing a processing procedure of the shooting effect determination apparatus 5 of the present invention. The flowchart of FIG. 3 shows a process of receiving smoke screen data 27 from the data receiving unit 23 and storing the smoke screen range. The control unit 22 of the shooting effect determination apparatus 5 performs processing as follows.

  The control unit 22 repeats the process of step S30 until the smoke screen data 27 is received from the data receiving unit 23. When the control unit 22 receives the smoke screen data 27 from the data receiving unit 23, the control unit 22 proceeds to step S31. The control unit 22 determines whether or not the smoke screen data 27 received from the data receiving unit 23 is data defining a smoke screen range.

  If smoke screen data 27 is data defining the smoke screen range (YES in S31), control unit 22 proceeds to step S32, reads the smoke screen range and duration from smoke screen data 27, and stores them in memory 20. The smoke screen range is represented by vertex coordinates in the case of a polygon, and is represented by center coordinates and a radius in the case of a circle.

  If the smoke screen data 27 is not data defining the smoke screen range (NO in S31), the control unit 22 proceeds to step S33, reads the impact position of the smoke bomb from the smoke screen data 27, and the smoke screen range according to the impact position. And the duration are calculated and stored in the memory 20. For example, the control unit 22 sets the range of the radius R (m) from the landing position of the smoke bomb as the smoke screen range and sets the time T (seconds) from the time of landing of the smoke bomb as the duration. The radius R (m) and the time T (seconds) are set as preset constants or are variable according to the number and type of smoke bombs. In this case, the smoke screen data 27 includes the impact position, the impact time, the number of smoke bullets, and the type.

  Progressing to step S34 following step S32 or S33, the control unit 22 determines whether or not the weather data 28 has been received from the data receiving unit 23. If the control part 22 has received the weather data 28 from the data receiving part 23, it will progress to step S35. If not received, the control unit 22 periodically repeats the process of step S34 until it is received.

  In step S <b> 35, the control unit 22 calculates the diffusion range and duration of the smoke curtain range according to the wind direction and wind speed information included in the weather data 28. For example, when the smoke screen range is a circle, the control unit 22 moves the center coordinates in the direction of the wind by wind speed × elapsed time. The control unit 22 stores the calculated diffusion range and duration of the smoke screen range in the memory 20.

  The processes in steps S34 and S35 can be periodically repeated for the duration of the smoke screen range to calculate the diffusion range of the smoke screen range over time. The process shown in FIG. 3 is performed for each received smoke screen data 27, and the calculated smoke screen range, diffusion range, and duration are stored in the memory 20, respectively.

  In the process shown in the flowchart of FIG. 3, the table of FIG. 4 or 5 is stored in the memory 20. FIG. 4 is an example table showing the smoke range and duration. FIG. 5 is an example table showing smoke range, duration and density.

  The table of FIG. 4 represents the smoke screen (diffusion) range and duration of a certain smoke screen 6. In the case of the table of FIG. 4, the first record from the top represents an example in which the smoke screen range is a polygon. When the smoke screen range is an n-gon, the smoke screen range is represented by n vertex coordinates (Xn, Yn). The duration of the smoke screen 6 is represented by the generation time and the extinction time of the smoke screen 6. The second record from the top represents an example where the smoke screen range is a circle. When the smoke screen range is a circle, the smoke screen range is represented by the center coordinates (Xn, Yn) and the radius Rn.

  The table of FIG. 5 represents the smoke screen (diffusion) range, duration, and density of a certain smoke screen 6. The table of FIG. 5 is configured by adding the item “density” to the table of FIG. The density of the smoke screen 6 is calculated, for example, by an expression (for example, density Cn = initial density C0−at) that becomes the highest density at the time when the smoke screen 6 is generated and becomes lighter as the time t elapses. That's fine.

  FIG. 6 is a flowchart of an embodiment showing a processing procedure of the shooting effect determination apparatus 5 of the present invention. The flowchart of FIG. 6 shows processing for determining the degree of wear reflecting the effect of the smoke screen 6 when the bullet data 26 is received from the laser light receiving unit 21. The control unit 22 of the shooting effect determination apparatus 5 performs processing as follows.

  The control unit 22 repeats the process of step S41 until the bullet data 26 is received from the laser light receiving unit 21. When receiving the bullet data 26 from the laser light receiving unit 21, the control unit 22 proceeds to step S42. The control unit 22 determines whether or not there is a smoke screen range based on whether or not the smoke screen range is stored in the memory 20.

  If there is a smoke range (YES in S42), control unit 22 proceeds to step S43. In step S43, the control unit 22 calculates a trajectory expression representing the trajectory of the laser beam 3 from the position of the shooter and the current position received as the position data 29 from the position locating unit 24.

  In step S44, the control unit 22 determines whether or not the locus of the laser beam 3 passes through the smoke screen range. Whether or not the locus of the laser beam 3 passes through the smoke screen range can be determined, for example, based on whether or not the locus formula calculated in step S43 has an intersection with the smoke screen range.

  When the smoke screen range is recorded at each vertex coordinate of the polygon, the control unit 22 determines whether each side of the polygon and the trajectory equation calculated in step S43 have intersections. It is determined that the smoke screen range is passed. When the smoke screen range is recorded as a circle, the control unit 22 calculates the minimum distance between the center coordinates of the circle and the locus formula calculated in step S43, and passes through the smoke screen range when the minimum distance is smaller than the radius of the circle. Judge that.

  When a plurality of smoke screen ranges are stored at the same time, the control unit 22 determines in step S44 for each smoke screen range. If the trajectory of the laser beam 3 passes through the smoke screen range (YES in S44), the control unit 22 proceeds to step S45, and in addition to the intensity of the laser signal included in the hit data 26, the type of fired fire, the type of bullet, the smoke screen The degree of wear is determined reflecting the effect of No. 6.

  On the other hand, when there is no smoke screen range (NO in S42) and when the locus of the laser beam 3 does not pass through the smoke screen range (NO in S44), the control unit 22 proceeds to step S46. In step S <b> 46, the control unit 22 determines the degree of wear by reflecting the intensity of the laser signal included in the bulleted data 26, the type of fired firearm, and the type of bullet.

  For example, when the smoke screen 6 is effective, the control unit 22 determines that there is no wear even when the bulleted data 26 is received. As another example, when the effect of the smoke screen 6 is obtained, the control unit 22 determines the degree of wear by multiplying the wear rate by the strength of the laser signal stored in advance for each firearm and bullet type by a certain value. .

  FIG. 7 is a table showing an example of the wear rate depending on the intensity of the laser signal stored for each fired firearm and bullet type. FIG. 8 is an example table showing the degree of wear due to the wear rate. For example, when there is an effect of the smoke screen 6, the control unit 22 reads out the wear rate based on the intensity of the laser signal stored for each fired weapon and bullet type from the table of FIG. 7, and the wear rate corresponds to the effect of the smoke screen 6. Multiply by a certain number (eg 0.5).

  Note that a variable numerical value that varies depending on the density may be used instead of a constant numerical value corresponding to the effect of the smoke screen 6. For example, by multiplying the wear rate by a value that approaches 0 when the concentration of the smoke screen 6 is high and approaches 1 when the concentration of the smoke screen 6 is low, the reality of the shooting training can be increased.

  The control unit 22 determines the degree of wear (for example, closeness, minor injury, serious injury, death, etc.) from the wear rate after multiplying by a constant value or variable value, according to the table of FIG. Progressing to step S47 following steps S45 and S46, the control unit 22 gives a display instruction 30 to the display unit 25 in accordance with the determination result of the shooting effect in order to display the degree of wear.

  As described above, according to the present invention, even when the smoke screen 6 is not actually generated, it is assumed that the smoke screen 6 is generated between the shooting person and the shot target, and the situation is determined as the effect of the shooting. Therefore, it is possible to carry out highly realistic shooting training without incurring costs.
