[0001] SUMMARY OF THE DISCLOSURE Embodiments of the present invention relate to a simulator, system, and method for simulating attrition in engagement training. [Background technology]

[0002] Traditionally, in combat training, the firing of rifles, heavy machine guns, armored vehicles, helicopters, etc. is replaced with lasers, and artillery fire is replaced with radio waves, and damage to the trainee is simulated by receiving the laser and radio waves with a receiver attached to the trainee.

[0003] Trainees are equipped with indicators that display this wear and tear.

[0004] This type of simulator includes a receiver that detects the laser energy and converts it into an electrical signal, and a display that displays the area hit by the laser. The receiver and display are modeled after a bulletproof vest and are integrated into the vest, and are connected by wires inside the vest. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2020-174272 A [Patent Document 2] U.S. Patent Application Publication No. 2012 / 183928 Summary of the Invention [Problem to be solved by the invention]

[0006] In combat training, in order to obtain sufficient training effectiveness, the following is required of the demonstrator:

[0007] First, it is necessary to minimize the difference between the actual equipment and the model. For example, if there is a large difference between the shape of the equipment worn in actual combat and the equipment worn during training, it will restrict the trainee's practice of basic movements.

[0008] In addition, it is necessary to be able to visualize the impact of enemy fire, because if troops cannot recognize the impact of enemy fire, they will not be able to practice appropriate evacuation maneuvers.

[0009] Furthermore, it is necessary to shorten the time required for advance preparations such as setting up the display as much as possible. For example, if it takes too much time for advance preparations such as setting up the display, the time that can be spent on training will be shortened accordingly.

[0010] However, in the conventional display, as described above, the receiver and the display are connected by wire inside the garment. If the number of receivers is small, for example, one, the configuration does not become too complicated even if the receiver and the display are connected by wire.

[0011] However, in order to indicate where a bullet has landed, multiple light receivers are required, and in order to determine whether the bullet has landed on, for example, the head, the right arm, the left arm, the torso, the right leg, or the left leg, the same number of light receivers are required.

[0012] Therefore, in order to accurately grasp the location of impact, a corresponding number of receivers are required. However, as the number of receivers increases, the number of wires also increases. Placing many wires inside the outerwear complicates the configuration of the display, which is not desirable. As the number of wires increases, the risk of wire breakage during training also increases. If a wire breaks, it is necessary to repair and prepare for the next training, but even identifying the location of the breakage in order to repair it takes time and effort. Naturally, it is not desirable to require time and effort for preparation, including repairs.

[0013] In addition, the number of receivers and their installation positions may be changed depending on the purpose and content of the training. Therefore, it is preferable that the simulator has a flexible configuration that can easily accommodate an increase or decrease in the number of receivers and changes in their installation positions.

[0014] The problem that the present invention aims to solve is to provide a display device, display system, and display method which, before training, allows for easy and error-free pairing settings with receivers and registration of receiver installation positions even if there are changes in the number of receivers or their installation positions, and which, by performing communication with the receivers wirelessly during training, eliminates the need for wiring between the receivers and simplifies the configuration, thereby not interfering with training and eliminating the risk of wire breakage, thereby eliminating the need for extra work such as repairs in preparation for the next training session. [Means for solving the problem]

[0015] The display device of the embodiment includes a wired connection unit that is wiredly connected to the optical receiver, a pairing setting unit that performs pairing settings for wireless communication with the optical receiver wiredly connected to the wired connection unit, an installation position registration unit that registers the position at which the paired optical receiver is installed in accordance with a specified input, a wireless communication unit that receives, via wireless communication, optical reception information from the optical receiver whose installation position has been registered and which has been disconnected from the wired connection unit, and a display data generation unit that generates display data for displaying the installation position of the optical receiver that is the source of the optical reception information.

[0017] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the size ratio between parts, etc. are not necessarily the same as the actual ones. Even when the same part is shown, the dimensions and ratios of each part may be different depending on the drawing. In this specification and each drawing, elements similar to those described above with respect to the previous drawings are given the same reference numerals, and detailed explanations and duplicated explanations are omitted as appropriate.

[0018] (First embodiment) A display system according to a first embodiment of the present invention will be described.

[0019] FIG. 1 is a conceptual diagram showing a state in which the display system of the first embodiment is used.

[0020] The display system of this embodiment includes a display device 10 and one or more optical receivers 40.

[0021] The simulator 10 is used by a trainee S during combat training. The simulator 10 can be realized by a small, portable terminal such as a smartphone. Therefore, the trainee S can perform combat training with the simulator 10 stored in the pocket of his outerwear or bulletproof vest. In addition, since smartphones have excellent expandability, this feature can be used to easily expand the displayed information.

[0022] During combat training, the receivers 40 are installed at various parts of the trainee S in a state capable of wireless communication with the simulator 10. For example, receiver 40(1) is installed on the head of the trainee S (attached to a helmet), receiver 40(2) is installed on the torso, receiver 40(3) is installed on the right foot, and receiver 40(4) is installed on the right arm.

[0023] The number of light receivers 40 is not limited to four, and may be one or more, three or less, or five or more. Also, the installation position may be changed depending on the training content.

[0024] When the receiver 40 detects laser energy, it converts the laser energy into an electrical signal, such as a voltage (V), and outputs it as light reception information. Therefore, when it is hit by a laser used instead of a shell during combat training, it generates light reception information and transmits it to the simulator 10. Therefore, the more receivers 40 there are, the more detailed information can be obtained from the combat training. However, the more receivers 40 there are, the lower the mobility of the trainee S becomes. Therefore, the number of receivers 40 is determined each time according to the content of the combat training.

[0025] In order to enable each receiver 40 to wirelessly communicate with the simulator 10 during the engagement training, each receiver 40 needs to be paired with the simulator 10 in advance before the engagement training. This pairing is performed while each receiver 40 is connected to the simulator 10 by wire.

[0026] FIG. 2 is a conceptual diagram showing a state in which the indicator and the receiver are connected by wire for pairing setup.

[0027] The simulator 10 includes a wired connection unit 17 that can be simultaneously connected to a plurality of receivers 40 (e.g., receivers 40(1)-(4)) via a cable 50. The simulator 10 includes various functions in addition to the wired connection unit 17. This will be described with reference to FIG. 3.

[0028] FIG. 3 is a block diagram showing an example of the electronic configuration of the indicator.

[0029] The display device 10, which can be realized, for example, by a mobile terminal such as a smartphone, comprises a CPU 12, a recording medium reading unit 14, a display unit 16, a wired connection unit 17, a wireless communication unit 18, a memory 20 storing various programs, and a storage device 30, all connected to each other by a bus 11.

[0030] The CPU 12 is a computer that controls the operation of each part in the simulator 10 in accordance with a program stored in the memory 20 .

[0031] The storage device 30 can be realized by a solid state drive (SSD) or a hard disk drive (HDD), etc.

[0032] The display unit 16 can be, for example, a liquid crystal display with a touch panel function, and can display (indicate) based on the light reception information from each receiver 40, and can allow the user to input necessary operations to the display device 10. The user is generally often the trainee S. Therefore, in the following description, the user and the trainee S may be regarded as the same person.

[0033] The memory 20 stores various programs for implementing the display device 10, and these programs implement a pairing setting unit 21, an installation position registration unit 22, and a display data generation unit 23.

[0034] The programs of the pairing setting unit 21, the installation position registration unit 22, and the display data generation unit 23 may be pre-stored in the memory 20, or may be read from an external recording medium 13 such as a memory card via the recording medium reading unit 14 and stored in the memory 20. The programs of the pairing setting unit 21, the installation position registration unit 22, and the display data generation unit 23 cannot be rewritten.

[0035] In addition to the area in which such non-rewritable programs are stored, the memory 20 also has a writable data area 29 secured therein as an area for storing rewritable data.

[0036] The pairing setting unit 21 performs pairing setting for wireless communication between each light receiver 40 connected to the wired connection unit 17 by wire and the display device 10.

[0037] The installation position registration unit 22 registers the installation position of the optical receiver 40 that has been paired by the pairing setting unit 21 in response to a designation input from the user. This designation input is made by the user in a state in which the target optical receiver 40 is connected by wire to the display 10. This designation input will be described with reference to FIG. 4.

[0038] FIG. 4 is a conceptual diagram showing the display screen of the indicator when registering the installation position.

[0039] The installation position registration unit 22 causes a display screen for installation position registration to be displayed on the display unit 16. An installation position map 100 and a menu field 110 are displayed on the display screen for installation position registration.

[0040] The installation position map 100 shows a simplified representation of the body parts of the trainee S. Also, in the menu section 110, various menus for inputting operation information to the simulator 10 are displayed.

[0041] When registering the installation position of the photoreceiver 40, the user taps "Settings" 110a in the menu field 110. Furthermore, the user taps the part of the body shown on the installation position map 100 where the photoreceiver 40 is to be installed. This causes the ID information of the photoreceiver 40 to be registered in the installation position corresponding to the tapped part. The ID information of the photoreceiver 40 is assigned in advance to each photoreceiver 40.

[0042] When the registration is completed, the user taps “Register” in the menu field 110. As a result, the installation position registration unit 22 generates linking information in which the installation position and the ID information are linked, and stores the generated linking information in the storage device 30.

[0043] In order to inform the user of the locations where the ID information of the photoreceiver 40 is registered, the installation position registration unit 22 displays the locations in a color different from that of unregistered locations on the installation position map 100. This allows the user to easily recognize the unregistered locations, and therefore allows the user to efficiently proceed with the registration process of the next installation position of the photoreceiver 40.

[0044] In addition, in Fig. 4, for the sake of simplicity, only one receiver 40 is connected by wire to the display device 10, but as exemplified in Fig. 2, it is also possible to perform registration processing of the installation positions of multiple receivers 40 in a state in which multiple receivers 40 are connected by wire to the display device 10. Even in a state in which multiple receivers 40 are connected by wire to the display device 10, the registration processing is performed for each receiver 40. In this case, unlike the case in which only one receiver 40 is connected by wire as in Fig. 4, it is not necessary to replace the cable 50 each time the registration processing of one receiver 40 is completed, so the effort required for replacing the cable 50 can be reduced.

[0045] In order to perform registration processing for each of the optical receivers 40 in a state where multiple optical receivers 40 are wired connected to the display 10, for example, priorities are assigned in advance to the branch cables 50(1)-(4) shown in Fig. 2, and when registration processing for the optical receiver 40(1) connected to the branch cable 50(1) with the first priority is completed, registration processing for the optical receiver 40(2) connected to the branch cable 50(2) with the second priority is performed in that order. However, the method for performing registration processing for each of the optical receivers 40 in a state where multiple optical receivers 40 are wired connected to the display 10 is not limited to this method, and any other method may be used.

[0046] In this way, when pairing of the receiver 40 with the simulator 10 and registration processing of the installation position of the receiver 40 are completed, the user (trainee S) disconnects the receiver 40 from the wired connection unit 17. This is performed by unplugging the cable 50 from the wired connection unit 17 and further unplugging each of the branch cables 50(1)-(4) from each of the receivers 40(1)-(4). The trainee S then installs each of the receivers 40(1)-(4) in the registered installation positions. This completes preparations for engagement training.

[0047] The photoreceiver 40 includes a photoreceiving section that senses laser energy and converts the sensed laser energy into an electrical signal, such as a voltage (V), and a transmitting section that transmits received light information including this electrical signal and ID information.

[0048] The wireless communication unit 18 can wirelessly communicate with the optical receiver 40 using a wireless function such as BLUETOOTH (registered trademark). Therefore, the wireless communication unit 18 receives the optical reception information transmitted from the optical receiver 40 using this wireless function. The wireless communication unit 18 further outputs the received optical reception information to the memory 20 via the bus 11.

[0049] In addition, when light reception information is transmitted simultaneously from multiple light receivers 40, the wireless communication unit 18 can simultaneously receive the multiple light reception information transmitted from the multiple light receivers 40 and output each piece of light reception information to the memory 20 via the bus 11.

[0050] When the light reception information is output to the memory 20, the display data generation unit 23 acquires ID information from the light reception information. Then, the display data generation unit 23 searches the storage device 30 for linking information that includes the acquired ID information. Since the linking information links the installation position with the ID information, the display data generation unit 23 identifies the installation position of the light receiver 40 that is the transmission source by searching for the linking information. Then, the display data generation unit 23 generates display data for displaying the identified installation position so that the degree of wear can be seen.

[0051] One example of a display that allows the degree of wear to be understood is, but is not limited to, changing the color density according to the magnitude of the voltage indicated by the electrical signal included in the received light information. Therefore, the display data generating unit 23 generates display data such that, for example, the greater the value of the voltage indicated by the electrical signal, the darker the display.

[0052] The display data generating unit 23 generates display data in which the identified installation position and the darkness are specified in this manner, and outputs the display data to the display unit 16.

[0053] The display unit 16 performs display based on the display data.

[0054] FIG. 5 is a diagram showing an example of a display device in which display data is displayed on a display unit.

[0055] Fig. 5 also shows a state where a display based on the display data is made on the display unit 16. In the example of Fig. 5, the head area is displayed with a dark fill, and the right leg area is displayed with a light fill. By looking at such a display, the trainee S can easily recognize that the areas where the trainee was shot were the head and the right leg, that the head sustained a large amount of damage, and that the right leg sustained a small amount of damage.

[0056] In this way, in the demonstrator 10, hardware such as the bus 11, CPU 12, recording medium reading unit 14, display unit 16, wired connection unit 17, wireless communication unit 18, memory 20, and storage device 30 work in cooperation with software, which are the various programs stored in the memory 20.

[0057] As described above, according to the simulation system of this embodiment, before training, pairing settings for wireless communication between each receiver 40 and the simulator 10 are performed using a wired connection, and the installation positions are registered. Then, each receiver 40 is disconnected from the wired connection with the simulator 10, and is installed at the registered installation position for training. During training, when the trainee S is shot with a laser, the receiver 40 detects the laser energy, and the light reception information generated in response thereto is transmitted to the simulator 10 by wireless communication using BLUETOOTH (registered trademark) or the like.

[0058] As a result, the simulator 10 can simulate the degree of damage at each position of the trainee S based on the received light information from the multiple receivers 40 installed at different positions on the trainee S. This allows the trainee S to recognize the impact of bullets during training and to practice appropriate evacuation actions.

[0059] Thus, the characteristic of the display system of this embodiment is that the pairing settings and registration of the installation location, which are performed as preparations before the training, are performed via wired connection, and during the training, the light reception information transmitted from the receiver 40 is received wirelessly.

[0060] Although pairing settings and installation location registration can also be performed wirelessly, this is not done in the present embodiment of the display system because performing pairing settings and installation location registration wirelessly would make things more complicated and would increase the risk of errors occurring in pairing settings and installation location registration.

[0061] For example, if the simulator 10 and the receiver 40 are physically connected via a wired connection, the trainee S can explicitly know which receiver 40 is the target of the pairing setting.

[0062] On the other hand, when pairing and registration of the installation position are performed wirelessly, the indicator 10 and the receiver 40 are not physically connected, so it is difficult to explicitly grasp which receiver 40 is the target of pairing. This will be explained in an easy-to-understand manner using Figure 6.

[0063] FIG. 6 is a diagram for explaining a case where pairing setting and registration of an installation location are performed wirelessly.

[0064] For example, when the simulator 10 performs pairing with the receiver 40 via BLUETOOTH, the simulator 10 recognizes all nearby receivers 40 that are capable of wireless communication via BLUETOOTH. This includes not only the receiver 40 used by a trainee S (for example, trainee A shown in FIG. 6) but also receivers 40 used by other trainees (for example, trainees B and C shown in FIG. 6). In this case, the simulator 10 displays a list of many receivers 40 that are wirelessly communicating on the display unit 16.

[0065] The trainee S must first identify the receiver 40 that he or she will use from the list displayed in this manner, including the receivers 40 used by the other trainees. However, the receivers 40 displayed in a list on the display unit 16 of the simulator 10 are not classified according to the trainees A, B, and C.

[0066] Therefore, when there are a large number of receivers 40 within the wireless communication range of the indicator 10, it takes time to correctly identify which receiver 40 is to be used among the displayed receivers 40. Therefore, there is a risk of misidentification.

[0067] In this way, if the pairing setting and the registration of the installation position are also performed wirelessly, there is a risk of mistakenly pairing with the optical receiver 40 of another trainee.

[0068] If such a mistake is noticed, it will take extra time to correct it, which will put pressure on the training time. Also, it cannot be ruled out that the mistake may not be noticed and the training may be continued as it is. In this case, it will have a big impact, such as making it impossible to properly evaluate the results of the training.

[0069] However, in the display system of this embodiment, the pairing setting and the registration of the installation position are performed by wire, so it is easy to know which receiver 40 is the target of the pairing setting. Therefore, the trainee S does not need to correctly know which receiver 40 he or she is using from among a large number of receivers 40, which is required when the pairing setting and the registration of the installation position are performed wirelessly. Therefore, it becomes easy to correctly perform the pairing setting of the receiver 40 and the registration of the installation position without confusing it with the receiver 40 of another trainee.

[0070] Furthermore, in the demonstration system of this embodiment, communication between the receiver 40 and the demonstration device 10 is performed wirelessly during training, which not only simplifies the configuration but also eliminates the risk of wiring being broken during training.

[0071] In addition, even if the number of receivers or their installation locations need to be changed depending on the purpose and content of the training, there is no need to add or rewire the wiring, making it flexible enough to easily accommodate this.

[0072] In this way, according to the demonstration system of this embodiment, by utilizing the advantages of both wired and wireless connections, by connecting the receiver 40 and the demonstration device 10 with a wire before training, even if there is a change in the number of receivers 40 or their installation positions, pairing settings with the receiver 40 and registration of the installation positions of the receiver 40 can be easily performed without error, and by connecting the receiver 40 and the demonstration device 10 wirelessly during training, wiring between the receiver 40 and the demonstration device 10 is not required and the risk of disconnection is eliminated, so that extra work such as repairs can be avoided in preparation for the next training.

[0073] Second embodiment A display system according to a second embodiment of the present invention will now be described.

[0074] Since the display system of the second embodiment is a partial modification of the display system of the first embodiment, the following will explain the differences from the first embodiment, and the same parts will be described using the same numbers to avoid duplicate explanations.

[0075] FIG. 7 is a conceptual diagram showing a configuration example of the display system of the second embodiment.

[0076] The display system of this embodiment includes a switch 51 in addition to the display device 10 and the optical receiver 40. The switch 51 operates the installation position registration unit 22.

[0077] FIG. 7 shows an example in which a button-type switch 51 is provided midway along the cable 50.

[0078] In the first embodiment described above, when the user sets the installation position of the optical receiver 40, the user taps “Register” from the menu field 110, whereby the installation position registration unit 22 generates linking information linking the installation position with the ID information, and stores the generated linking information in the storage device 30.

[0079] With such software-based operations, there is a risk that the user may tap in the wrong position and select a different menu, or may tap but not actually do so, or may think that the installation position registration unit 22 has not been activated even though the user intended to register the installation position.

[0080] Therefore, in this embodiment, the user operates the installation location registration unit 22 not by a software operation such as tapping “Register” from the menu field 110, but by a mechanical operation such as pressing the button of the switch 51.

[0081] When the switch 51 is pressed, a signal for operating the installation position registration unit 22 is transmitted to the model 10 via the cable 50. In response to this signal, the installation position registration unit 22 operates.

[0082] Such mechanical operation can eliminate the possibility of operational errors resulting from the software-based operation described above.

[0083] FIG. 7 shows a configuration example in which the switch 51 is provided on the cable 50 to which one light receiver 40 is connected, but other configuration examples will be described below with reference to FIGS. 8 to 10.

[0084] FIG. 8 is a conceptual diagram showing another configuration example of the display system of the second embodiment.

[0085] As shown in FIG. 8, a switch 51 may be provided on a cable 50 to which a plurality of photoreceivers 40 are connected.

[0086] FIG. 9 is a conceptual diagram showing yet another configuration example of the display system of the second embodiment.

[0087] As shown in FIG. 9, the switch 51 may be provided in the optical receiver 40 instead of in the cable 50 .

[0088] FIG. 10 is a conceptual diagram showing yet another configuration example of the display system of the second embodiment.

[0089] As shown in FIG. 10, a plurality of receivers 40 ( 1 ) to ( 4 ) each provided with a switch 51 can be connected to the indicator 10 by a cable 50 capable of connecting the plurality of receivers 40 .

[0090] (Third embodiment) A display system according to a third embodiment of the present invention will now be described.

[0091] Since the display system of the third embodiment is a partial modification of the display system of the first or second embodiment, the following will explain the differences from the first or second embodiment, and the same parts will be described using the same numbers to avoid duplicate explanations.

[0092] FIG. 11 is a side cross-sectional view showing a configuration example of a storage case applied to the display system of the third embodiment.

[0093] The display system of this embodiment includes a storage case 60 in addition to the display device 10 and the receiver 40.

[0094] FIG. 12 is a perspective view showing an example of the configuration of the storage case 60. As shown in FIG.

[0095] The storage case 60 is provided with a recess 61 for storing the receiver 40 and a recess 63 for storing the indicator 10.

[0096] FIG. 11 corresponds to a cross-sectional view taken along line AA in FIG. 12 when the light receiver 40 is housed in the recess 61 and the indicator 10 is housed in the recess 63. FIG.

[0097] A connection terminal 62 is provided on the bottom surface of the recess 61 . When the optical receiver 40 is housed in the recess 61 , the connection terminal 62 comes into contact with the communication terminal of the optical receiver 40 and is electrically connected to the optical receiver 40 .

[0098] A connection terminal 64 is provided on the bottom surface of the recess 63, which comes into contact with the communication terminal of the simulator 10 and is electrically connected to the simulator 10 when the simulator 10 is stored in the recess 63.

[0099] The connection terminal 62 and the connection terminal 64 are connected by a cable 50 .

[0100] This allows the storage case 60 to store the indicator 10 and the receiver 40 while they are wired connected via the cable 50.

[0101] FIG. 13 is a side cross-sectional view showing another example of the configuration of the storage case.

[0102] As shown in FIG. 13, the storage case 60 can also be provided with a switch 51 as described in the second embodiment.

[0103] 13 is also connected to the cable 50 inside the storage case 60. When the button is pressed, a signal for operating the installation position registration unit 22 is transmitted to the modeler 10 via the cable 50. In response to this signal, the installation position registration unit 22 operates.

[0104] As described above, according to the display system of this embodiment, the display device 10 and the receiver 40 can be connected via a wired connection by storing them in the storage case 60. Therefore, in addition to the effects achieved by the display systems of the first and second embodiments, there is no need to reconnect the cable 50, thereby saving time and effort.

[0105] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope of the invention and its equivalents described in the claims, as well as in the scope and spirit of the invention.
