Description

  The present invention relates to a shooting training system for simulating shooting training, and more particularly to a shooting training system that performs shooting training by transmitting and receiving signal waves between a transmitting device and a receiving device. It is.

  Conventionally, in the simulation of shooting training, the effectiveness of hitting by the information contained in the optical signal that is shot (transmitted) from the shooting device (transmitting device) to the target device (receiving device) and reflected from the target device Has been confirmed (see, for example, Patent Document 1). FIG. 3 is a system diagram of a conventional shooting training system applied to a shooting training simulation. In this figure, only one of the transmission device side and the reception device side is displayed, but both devices have the same configuration. Therefore, a case will be described in which this system diagram is on the transmission device side or the reception device side.

  In FIG. 3, the optical transmitter 11 on the transmission device side receives an optical signal including information such as the transmission time, the type of transmission signal, the individual number of the transmission signal, and the distance between the transmission device and the reception device. , The optical receiver 12 on the receiving device side receives the optical signal transmitted from the transmitting device side and converts it into an electrical signal. And the controller 13 received the information (that is, the transmission time, the type of the transmission signal, the individual number of the transmission signal, the distance between the transmission device and the reception device, etc.) included in the reception signal converted into the electric signal. Information such as the receiving part at the time is analyzed and it is determined whether or not the optical signal hits the target on the receiving apparatus side. Here, when the optical signal hits the target, the controller 13 performs control so that the indicator 14 is indicated by sound, light, smoke, or the like.

  Furthermore, since the controller 13 transmits information on whether or not the optical signal has been hit to the radio unit 15, the radio unit 15 transmits information on whether or not to hit a control station (not shown) by radio. At this time, the optical signal communicated between the transmission device and the reception device is a laser beam, near infrared light, visible light, or the like, but a laser beam with good directivity is usually used. The conventional shooting training system thus transmits an optical signal including information from the transmitting device toward the target of the receiving device, and hits by the hit information included in the optical signal transmitted back from the receiving device. It is confirmed whether or not.

In addition, since the laser beam has good directivity, it can reach a target far away. Therefore, there is a possibility that the receiving apparatus receives a laser beam for shooting training performed in another place. Therefore, a technology is disclosed in which it is determined whether or not the receiving apparatus has received a laser beam from a different shooting training field, and only the laser beam received from the other transmitting apparatus is determined to be hit. This technology can be used only when GPS (Global Positioning System) grasps the positional information of the transmitting device and the receiving device, and the arrival distance of the laser beam received by the receiving device matches the positional information measured by GPS. It is determined that the laser beam is hit (see, for example, Patent Document 2).

  However, since the conventional shooting training system uses a laser beam for the transmission system, it must be aimed and transmitted directly to the target (receiving device). In other words, the laser beam is a very narrow beam and has the property of propagating in a straight direction with high directivity, so it is possible to perform training with a depression angle (for example, arc training to draw an arc) like a real firearm. Can not. Furthermore, since the laser beam is coherent light (coherent light) with little spread, it is blocked even if there are a few obstacles. For this reason, the laser beam cannot be used if there are obstacles such as grass or trees in the front or fog is generated. For example, in a shooting training over a mountain where the line-of-sight does not work, since the laser beam does not reach the target (receiving device), it cannot be determined whether the laser beam has landed (received) on the target (receiving device).

  The present invention has been made in view of the above problems, and uses a signal wave that is not a laser beam for a transmission system, and at the same time, confirms the position information and transmission direction of a target by a sensor and simulates a curvature training. The aim is to provide a shooting training system that can

  In order to solve the above-described problem, a shooting training system according to the present invention is a shooting training system in which a radio wave is transmitted from a transmission device to a reception device, and a control unit performs shooting training by monitoring the transmission direction of the radio wave. The transmitting device includes a wireless unit that transmits a radio wave to the receiving device and transmits / receives a radio wave to / from the control unit, a GPS receiving unit that captures position information of the receiving device from a GPS satellite, and a wireless unit. A detecting means for detecting the transmission direction and transmission angle of the radio wave transmitted to the receiving device and its own running acceleration, and the control means transmits the positional information captured by the GPS receiving means and the transmission direction and transmission detected by the detecting means. Based on the angle and the traveling acceleration, the receiving part of the radio wave in the receiving device is determined, and the determination result is notified to the wireless means.

  The shooting training system of the present invention does not use a laser beam with high linear directivity as a simulated bullet, but uses a radio wave capable of correcting the trajectory as a simulated bullet. Then, based on the position information of the receiving device captured by the GPS receiving unit and the transmission direction, transmission angle, and traveling acceleration of the radio wave detected by the detection unit, the control unit determines the radio wave reception site in the receiving device. Judgment. When the receiving part is corrected, the transmitting device can correct the transmission direction of the radio wave (ballistic correction) by notifying the transmitting device from the control means. This makes it possible to simulate a music shooting.

  As described in detail above, according to the shooting training system of the present invention, a radio wave capable of correcting the trajectory is used as a signal wave for shooting training, instead of using a laser beam that can only be aimed directly. Furthermore, the trajectory direction of the radio wave is corrected based on the shooting direction, the shooting angle, the traveling acceleration of the radio wave, and the position information of the target device by D-GPS. Thereby, it is possible to hit the target device in the shadow by the curved shooting. In this way, it is possible to perform a music firer simulation as a shooting simulation training that does not use a laser beam. Thereby, in an environment closer to the actual battle, a shooting training can be performed on a short-distance and long-distance target by combining direct aiming and music shooting processing.

  Hereinafter, embodiments of a shooting training system according to the present invention will be described with reference to the drawings. First, an outline of a shooting training system according to the present invention will be described. The shooting training system of the present invention measures position information of a shooting device (transmitting device) and a target device (receiving device) in advance by a D-GPS (Differential-Global Positioning System) that performs high-precision positioning using FM multiplexed signals. . When a radio wave signal is emitted (transmitted) from the shooting device to the target device, the shooting direction (shooting angle) measured by the sensor at the shooting point (transmission point), the shooting angle, and the travel acceleration and the position information measured by the D-GPS are transmitted as radio waves. Send to control office by signal. In the following description, the shooting device and the transmission device, the target device and the reception device, the launch and transmission, the shooting point and the transmission point, the landing and reception, and the landing position and the reception position are used as synonyms, respectively. Any term may be used.

  Next, the control station determines the landing position of the target device based on information included in the radio signal transmitted from the shooting device (that is, shooting direction, shooting angle, travel acceleration, and position information by D-GPS). Then, the determination result is returned to the shooting device by a radio signal. Thereby, the shooting device can perform a shooting training simulation while correcting the shooting direction and the shooting angle based on the determination result. Therefore, unlike the conventional case where a highly directional laser beam is emitted (transmitted) to the target device, the radio wave signal is reliably landed (received) even in shooting training over a mountain where the line-of-sight does not work. Can be made.

  Next, the shooting training system according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a system diagram of a shooting training system according to the present invention applied to a shooting training simulation. In FIG. 1, the shooting training system of the present invention is broadly divided into a transmitting device 1 that is a shooting device that transmits radio waves, a receiving device 2 that is a target device that receives radio waves, and a transmitting device 1 to a receiving device. The control station 3 is configured to determine whether or not the radio wave transmitted to 2 hits.

  Further, the transmission device 1 includes a wireless device 4 that transmits and receives various data by radio waves, a GPS receiver 5 that receives position information from a GPS satellite 9, a detector 6 that incorporates various sensors, and the entire transmission device 1. It comprises a controller 7 that performs the above control and a display device 8 that displays the sound, light, smoke, etc. according to the hit information received from the control station 3.

  The wireless device 4 has a function of transmitting and receiving wireless radio waves including various data to and from the receiving device 2 serving as a target device, and transmitting and receiving wireless radio waves including various data to and from the control center 3. . The GPS receiver 5 has a function of measuring the positions of the transmission device 1 and the reception device 2 with high accuracy by D-GPS using FM multiplex signals. Further, the detector 6 includes a direction (shooting direction) indicating a transmission direction of a radio wave transmitted by the transmission device 1, an angle (shooting angle) indicating a transmission angle of the radio wave, and its own travel acceleration (movement acceleration or shooting). Acceleration). The azimuth / angle / acceleration sensor can be realized by using a semiconductor system, a gyro system, an image processing system using a CCD camera, or the like.

  Next, the operation from shooting to landing by the shooting training simulation apparatus shown in FIG. 1 will be described. When a radio wave is transmitted from the wireless device 4 to the target receiving device 2, the detector 6 detects the transmission direction, the transmission angle, and the traveling acceleration of the radio wave. Further, the GPS receiver 5 captures position information of the transmission device 1 and the reception device 2 by the GPS satellite 9. The controller 7 transmits the radio wave based on the transmission direction, transmission angle, and traveling acceleration of the radio wave detected by the detector 6 and the positional information of the transmission device 1 and the reception device 2 captured by the GPS receiver 5. Create data. The contents of the radio wave transmission data at this time are a radio wave transmission time, a transmission signal type, an individual number, a reception part, a position of a reception device, a transmission direction, a transmission angle, and a traveling acceleration.

  When these radio wave transmission data are transmitted from the wireless device 1 to the control station 3, the control station 3 calculates the content of the received radio wave transmission data and calculates the reception position (landing position) of the radio wave in the receiving device. . If the receiving position is that of the receiving device 2 corresponding to the transmitting device 1, the landing data is transmitted to the transmitting device 1. Then, the controller 7 of the transmitter 1 causes the indicator 5 to display sound, light, smoke, etc. in order to display that the radio wave has hit the receiver 2.

  FIG. 2 is an image diagram showing straight line shooting by a conventional shooting training system and curved shooting by the shooting training system of the present invention. As shown in FIG. 2, in the conventional shooting training system, since the laser beam S2 having high linear directivity is emitted from the shooting device (transmitting device) 21, the target device (receiving device) is present when there is an obstacle 23 ahead. ) Can't hit 22 In other words, conventional shooting training using a laser beam can only aim directly in a linear direction.

  However, in the shooting training system of the present invention, the radio wave S1 emitted from the shooting device (transmitting device) 21 is subjected to ballistic correction by calculating the shooting ballistics based on the detection data of various sensors. Accordingly, since the curved obstacle shooting can be performed while avoiding the obstacle 23 ahead, the shooting device (transmitting device) 21 can reliably hit the target device (receiving device) 22 with the radio wave S1. That is, in the shooting training system of the present invention, the sensor of the shooting device (transmitting device) 21 detects the shooting direction, shooting angle, and traveling acceleration of the radio wave S1, and the GPS receiver detects position information by the GPS satellite. Since the trajectory correction of the radio wave S1 is performed based on the detection information, it is possible to perform music shooting from an object.

  Then, the shooting device (transmitting device) 21 notifies the control station (not shown) of data of the transmission direction, the transmission angle, the traveling acceleration, and the position information. Thereby, the control center calculates the landing position (reception position) of the target apparatus (reception apparatus) 22 from the acquired data. Furthermore, since the control station notifies the landing position (reception position) to the shooting device (transmitting device) 21, the shooting device (transmitting device) 21 modifies the transmission direction and transmission angle of the radio wave S1 as necessary. A new target can be set and fired (transmitted). In this way, the shooting device (transmitting device) 21 can perform a song shooting simulation using the radio wave S1.

  In the shooting training system of the present invention, each component of the transmission device 1 as shown in FIG. 1 is mounted on an aircraft, a vehicle, or a human body, and wireless signals are transmitted to and received from the control station 3, thereby preventing shooting. Judgment and evaluation up to landing can be performed accurately and instantaneously.

It is a systematic diagram of the shooting training system of the present invention applied to a shooting training simulation. It is an image figure which shows the linear shooting by the conventional shooting training system, and the music shooting by the shooting training system of this invention. It is a systematic diagram of the conventional shooting training system applied to the simulation of shooting training.
