Description

[Technical field]

[0001] The present invention relates to a shooting training system using live ammunition, and in particular to a shooting training system that can determine the wear and tear of a target and consumables placed behind the target and notify the user when it is time to replace them, thereby improving the safety of training and the maintenance efficiency. [Background technology]

[0002] Description of the Prior Art Conventionally, in shooting training systems that use live ammunition for shooting training, for example, some systems detect the vibrations of a target when it is shot at and cause the target to fall when the bullet hits it, while others use a sensor to detect the shock waves of the bullet, etc., to determine the impact position and display the impact position (coordinates) on a display. In addition, for firearms with slow initial velocities such as handguns, a rubber-type sensor is used to detect the bullet's passing position, rather than a sensor that detects shock waves.

[0003] [Outline of conventional bullet impact management: Figure 14] In conventional target practice systems, a terminal wirelessly connected to a sensor counts the number of hits on each target and stores them in a database, tallying up the number of hits on the targets, which are consumables, but the replacement of consumables is carried out after visually checking the wear and tear on the targets. The terminal is equipped with a control unit, a display unit, an operation unit, and a database. An overview of conventional management of the number of landing bullets will be described with reference to Fig. 14. Fig. 14 is an explanatory diagram showing an overview of conventional management of the number of landing bullets.

[0004] As shown in Figure 14, in a conventional shooting training system, the control unit of the terminal compiles the number of bullets that have hit each target for each training day based on data from a sensor attached to the target, stores the results in a database within the terminal, and also compiles the cumulative number of bullets that have hit each target for a specific period of time.

[0005] In the example of Figure 14, the number of hits on targets A, B, ... and E for each training date of May 10, May 12, ... and June 25, 2021, is stored in the database. Then, in response to an instruction from the operation section of the terminal, the cumulative number of hits for each target during a specific period of time is displayed on the display section.

[0006] [Example of conventional bullet impact count display: Figure 15] A conventional example of displaying the number of impact bullets will be described with reference to Fig. 15. Fig. 15 is an explanatory diagram showing a conventional example of displaying the number of impact bullets. As shown in FIG. 15, in a conventional target practice system, when a collection period is specified and a command to collect data is input, the number of hits for each target during that period is collected and the collected results are displayed.

[0007] However, in the past, maintenance personnel were not able to clearly recognize when each consumable item should be replaced, and instead replaced them periodically or visually checked the condition of holes in the targets and the bullet-stopping embankments installed behind the targets, resulting in problems such as replacing items that were still usable, or not realizing that damage to the target caused a false positive (failure to detect impact), and having to reshoot.

[0008] [Related Technology] In addition, conventional technologies related to the shooting training system menu include JP 2017-009188 A “Shooting Training System” (Patent Document 1) and JP 2014-126257 A “Shooting Training System” (Patent Document 2). Patent Document 1 describes a shooting training system that generates and displays a list of shooting result information based on hit / miss information from a determination unit. Patent Document 2 describes a shooting training system that makes it easy to visually confirm the location of a bullet's impact by displaying the score based on the location of the hit and other shooting results in different colors on a screen. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] JP 2017-009188 A [Patent Document 2] JP 2014-126257 A Summary of the Invention [Problem to be solved by the invention]

[0010] However, with conventional shooting training systems, maintenance personnel were unable to clearly recognize when each consumable item needed to be replaced, which led to inconsistent replacement timing, which could result in unnecessary maintenance work or reduced safety and efficiency of training.

[0011] Furthermore, Patent Document 1 does not mention that the planned cumulative number of hits for each target is calculated for each planned training based on the cumulative number of hits for each target and the number of bullets used based on the training plan, and displayed in a list, and that if the planned cumulative number of hits exceeds the set threshold for the number of usable bullets, the target is displayed in color in the list.

[0014] The present invention also provides a processing device in the above-mentioned shooting training system. First wear level detection unit calculates the remaining number of usable bullets for each target by subtracting the cumulative number of hits from the usable number of bullets, and displays the usable number of bullets, the cumulative number of hits, and the remaining number for each target on the maintenance screen, The cumulative number of hits is the number of bullets that can be used. When the threshold value is exceeded, the remaining number is displayed in color.

[0015] The present invention also provides a processing device in the above-mentioned shooting training system. First wear level detection unit is characterized in that a plurality of threshold values ​​for the number of bullets that can be used are stored, and each threshold value is displayed in a different color.

[0017] Further, in the shooting training system of the present invention, the processing device is a bullet barrier installed behind the target. The third wear level detection unit detects the wear level of the stoppage breakwater.

Effect of the Invention

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings [Outline of the embodiment] In a shooting training system according to an embodiment of the present invention (this shooting training system), a control unit of a terminal which acquires information from a sensor and manages the number of bullets hit per target stores the number of bullets used for each target for each training of multiple training sessions scheduled for a certain period of time in the form of a training plan, and calculates the planned cumulative number of bullets hit for each target for each scheduled training session based on the cumulative number of bullets hit for each target up to the previous day and the number of bullets used in the training plan, and displays these in a list. If the planned cumulative number of bullets hit exceeds a set threshold for the number of usable bullets, the portion of the list displaying the planned cumulative number of bullets that exceeds the threshold is displayed in color, allowing maintenance personnel to recognize at a glance whether there are any targets that need to be replaced within a certain period of time, and by knowing in advance when each target should be replaced, they can replace the targets at the appropriate time, thereby improving the efficiency and safety of maintenance work and training.

[0023] In addition, in this shooting training system, the control unit of the terminal calculates the cumulative number of hits for each of a number of areas into which the entire target is divided into a mesh pattern, and if there is an area where the cumulative number of hits exceeds a specific threshold which is lower than the number of bullets that can withstand the entire target, an alarm regarding the replacement of the target is displayed.Even if the number of bullets that can withstand the entire target has not been reached, if there are areas that are severely damaged, such as near the center of the target, the system can prompt the user to replace the target, preventing false positives and improving safety.

[0024] In addition, this shooting training system stores information on the impact positions on the target and its surroundings in association with multiple stopping units mounted on the surface of a stopping wall installed behind the target, calculates an estimated cumulative number of impacts at each stopping unit based on the impact positions, and if the estimated cumulative number of impacts exceeds a threshold for the number of bullets that can be used by a stopping unit, displays an alarm regarding the replacement of that stopping unit, thereby alerting the user to the presence of a stopping unit that is likely to be damaged and encouraging the replacement of that stopping unit, thereby improving safety.

[0025] [Configuration of this shooting training system: Figure 1] The configuration of this targeting training system will be described with reference to Figure 1. Figure 1 is an explanatory diagram showing the configuration of this targeting training system. As shown in FIG. 1, the shooting training system is a system for a shooter to conduct shooting training in which the shooter uses a firearm 4 to fire live ammunition at a target, and is equipped with a target device 1, a bullet retaining wall 2, and a terminal 3. Furthermore, the target device 1 includes a target 11, a strike position detection sensor 12, and a control device 14. In some cases, a rubber type sensor is also included. In Fig. 1, a side view of the target device 1 is shown.

[0026] (Paragraph number 0010 in the model specification) The shooter uses a firearm 4 such as a gun to train by firing live bullets at a target 11 set up on a target device 1. The impact position is detected by an impact position detection sensor 12 on the target device 1, and is notified to a terminal 3 installed near the shooter, which then displays the impact position on its monitor. In addition, the training conditions such as the target to be used, the firearm to be used, etc. can be set from the terminal 3. The terminal 3 is installed near the shooter, so that the shooter can check the impact position, the score, etc. even if there is a distance between the shooter and the target 11. The terminal 3 and the control device 14 of the target device 1 input and output data by wireless or other means.

[0027] The bullet stopping embankment 2 is installed to prevent a shot bullet from bouncing back toward the shooter or ricocheting in an unspecified direction, and a number of bullet stopping units 22 are laid out on the front surface of a main body 21 formed in a sloping shape.

[0028] The surface of the bullet stopping unit 22 is covered with a bullet stopping material such as rubber, a rubber chip is provided inside, and a steel plate is provided below (behind) it. In the bullet stopping embankment 2, each bullet stopping unit 22 can be replaced.

[0029] [Example of target device 1 configuration: Figure 2] An example of the configuration of the target device 1 will be described with reference to Fig. 2. Fig. 2 is a front view showing the example of the configuration of the target device 1. The target device 1 includes a target 11, a bullet impact position detection sensor 12, and a control device . The target 11 has a plate-like shape, such as a human silhouette, and its movements, such as standing up and falling down, are controlled by a control device 14. When the target 11 is to be replaced due to wear, the entire target 11 is replaced.

[0030] The impact position detection sensor 12 is installed in front of the target 11 and detects the impact of a shot. The impact position detection sensor 12 can detect the impact of a shot on a detection area 20 that is larger than the target 11, and detects the impact of a shot on the detection area 20 regardless of whether the shot has landed on the target 11 or not. The detection area 20 is an area on the same plane as the target 11, and is set to be larger than the target 11. Impact position detection sensor 12 detects the position coordinates of the passing position in detection area 20 and sets them as impact coordinates. To detect the position coordinates of the bullet, multiple sensors that detect shock waves, multiple ultrasonic sensors, etc. are used, and impact position detection sensor 12 calculates the impact coordinates converted into XY coordinates in detection area 20 from the time when the multiple sensors detected the shock waves and the positional relationship between the multiple sensors. Then, impact position detection sensor 12 transmits the impact coordinates to terminal 3, which will be described later.

[0031] When the bullet hits the target, the impact position, time, score, etc. are displayed on the terminal 3, and the shooter can obtain the shooting result by looking at the monitor of the terminal 3. A known display on the monitor is disclosed in Patent Document 2. The score is calculated automatically, and the total score can also be displayed. In Patent Document 2, the score is calculated based on the coordinates calculated by the impact position calculation unit. This shooting evaluation system makes it possible to score based on the outer diameter of the bullet centered on the impact position, based on the impact coordinates and the caliber size of the firearm calculated from the detection results of the detector.

[0032] [Example of a shooting training system using rubber targets: Figures 3 and 4] However, in the case of firearms with slow initial velocity such as handguns, sensors that detect shock waves cannot detect the impact position. In such cases, rubber-type targets and sensors compatible with rubber-type targets are used. A shooting training system using a rubber-type target (another shooting training system) will be described with reference to Figures 3 and 4. Figure 3 is an explanatory diagram showing an example of the configuration of the other shooting training system, where (a) is an explanatory diagram showing an overview of the other shooting training system, and (b) is a front view of the target. Figure 4 is an explanatory diagram showing an example of the configuration of the rubber-type target.

[0033] As shown in Fig. 3(a), another target training system includes a target device 5 having a rubber-type target 51, a projector 13, and a sensor compatible with the rubber type. Other components are similar to those in Fig. 1. 3(b), the projector 13 projects and displays an image of a target 51. Moreover, the projector 13 is installed at the top or bottom so as to be bulletproof.

[0034] As shown in Figure 4, rubber-type target 51 has wooden frame 50 sandwiched between rubbers 52 and 53 on both sides, and multiple sensors 54 installed at the bottom of wooden frame 50 detect the passing position of the bullet. When a bullet passes through the rubber, the shock wave of the bullet is detected by multiple sensors 54 such as acoustic sensors and ultrasonic sensors, and the impact coordinates converted into XY coordinates in detection area 55 are calculated from the time when the multiple sensors 54 detected the shock wave and the positional relationship between the sensors. It is desirable that rubbers 52 and 53 are stretchable and self-repairing materials that can shrink a hole when a bullet penetrates. The rubber type compatible sensor 54 is capable of detecting coordinates not only in handguns but also in rifles.

[0035] The sensor 54 is equipped with a control device that transmits and receives data wirelessly to and from the terminal 3. For the target image to be projected onto the rubber-type target 51, the terminal 3 transmits image data of the target to the projector 13, and the projector 13 uses the received image data and video data to perform projection.

[0036] Terminal 3 generates image data for projecting a target on target device 5, transmits it to projector 13, receives a detection signal from impact position detection sensor 12, and calculates the impact position and score. Based on the calculated impact position and score, control unit 31 generates image data of the impact position and score to be projected on target device 5, and transmits it to projector 13, and projector 13 projects the impact position and score by superimposing them on the image of the target.

[0037] Furthermore, the terminal 3 of this shooting training system manages and sets training information and manages consumables (targets 11, bullet stopping units 22), and corresponds to the processing device recited in the claims. The terminal 3 sets training conditions such as the targets and firearms to be used as training information.

[0038] In addition, the terminal 3 of the shooting training system calculates the estimated cumulative number of hits on each target 11 for a certain period of time (for example, one week from now), and displays an alarm to prompt replacement when the estimated cumulative number of hits exceeds the number of bullets that the target 11 can withstand. The processing of the terminal 3 will be described later.

[0039] [Configuration of Terminal 3: Figure 5] Next, the schematic configuration of the terminal 3 will be described with reference to Fig. 5. Fig. 5 is an explanatory diagram showing the schematic configuration of the terminal 3. As shown in FIG. 5, the terminal 3 includes a control unit 31, a storage unit 32, a display unit 33, a wireless communication unit , and an operation unit . The control unit 31 is configured with a processor such as a CPU (Central Processing Unit), and reads and executes processing programs stored in the storage unit 32 to realize various processes in the terminal 3.

[0040] When a rubber type target device 5 is used, the control unit 31 performs, as basic operations, a target setting process for setting a target and generating a target image to be projected onto the target device 5, a landing position calculation process for calculating the impact position based on a detection signal received from the target device 5 and creating image data of the impact position, and a scoring process for calculating a score based on the calculated impact position. These are realized by executing corresponding processing programs. The score table stored in the memory unit 32 corresponds to the target image projected onto the rubber type target 51 of the target device 5, and records the score according to the impact point on the target image. A score table is created for each type of target image projected onto the target device 5, and in the scoring process, the score is calculated using the corresponding score table based on the impact position calculated in the impact position calculation process.

[0041] Furthermore, the control unit 31 of the terminal 3 transfers image data of the impact position and the score from the wireless communication unit 34 to the projector 13 in addition to the image data of the target, and the projector 13 superimposes the impact position and the score on the target image and projects it onto the rubber-type target 51. At this time, the control unit 31 performs an impact position calculation process to create image data in which the impact position is converted into a circle of a size recognizable by the shooter, centered on the calculated impact position coordinates, on the target image projected onto the rubber-type target 51, and the projector 13 uses the converted image data to project the impact position onto the rubber-type target 51. That is, the control unit 31 has a function of converting the image data based on the calculated impact position into image data of a size recognizable by the shooter on the target device 5 when generating the image data.

[0042] Furthermore, this target practice system performs a process of predicting and calculating the number of hits, which indicates the degree of wear of consumables, and clearly displaying the replacement time in advance. The process of the control unit 31 of the terminal 3 will be described later. The control unit 31 also manages the number of hits in the same way as in the conventional method shown in Figs. 14 and 12.

[0043] In addition to the processing program, the memory unit 32 stores, as a database, the cumulative number of hits on each target 11 for each training day, as in the conventional case, and a training plan, which is a characteristic part of the present shooting training system. The training plan will be described later. The memory unit 32 also stores a cumulative number of hits table and a planned cumulative number of hits table, which will be described later.

[0044] The wireless communication unit 34 wirelessly communicates with the impact position detection sensor 12 and the projector 13 via an antenna. The terminal 3 acquires information on the impact position from the impact position detection sensor 12. In addition, the terminal 3 transmits display data such as an image of a target, the impact position, and scores to the projector 13.

[0045] The display unit 33 performs a list display, which will be described later. The display unit 41 is a flat panel display (FPD) such as a liquid crystal display, and can display a control screen for the shooting system and information regarding bullet impact.

[0046] The operation unit 35 is an input unit operated by a person in charge of training or maintenance, and is composed of a keyboard, a mouse, a touch panel, and the like. Using the operation section 35, as described below, the display section 33 is set to subdivide the target 11 into a mesh, and each bullet stopping unit 22 of the bullet stopping wall 2 is set to correspond to the bullet impact position.

[0047] The storage unit 32 is composed of non-volatile memories such as a RAM (Random Access Memory), a ROM (Read Only Memory), a HDD (Hard Disc Drive), and a flash memory. In addition to the programs executed by the control unit 31, the storage unit 32 stores data necessary for controlling the target device 1 and the projector 13, and for analyzing the impact of bullets on the target device 1. For example, the storage unit 32 includes a plurality of score tables, a caliber table, and a target damage table used for scoring the impact. The caliber of the firearm used in the training is registered in advance in the caliber table. Furthermore, the storage unit 32 stores and accumulates the impact positions and scores that are the results of past shooting training for each shooter.

[0048] [Detection of consumable wear level] The terminal 3 of this shooting training system detects the degree of wear (wear level) of the targets 11, rubber-type targets 51, and bullet stopping units 22 of the bullet stopping embankment 2 at the present time or for a certain period of time, and displays an easy-to-understand indication of when to replace them. Note that this shooting training system detects the wear level and displays the replacement time regardless of the type of target, and in the following explanation, the targets 11 and targets 51 will be collectively referred to as targets 11.

[0049] Since the degree of attrition reflects the cumulative number of hits, this shooting training system detects the current cumulative number of hits as a numerical value indicating the degree of attrition, or predicts the expected cumulative number of hits for a certain period of time and displays it in a list.

[0050] In this shooting training system, it is possible to perform a first wear level detection that detects the wear level of each target 11 for a certain period of time into the future (for example, one week into the future), a second wear level detection that detects the wear level of each area obtained by dividing the target 11 into a mesh-like shape, and a third wear level detection that detects the wear level of the bullet stopping unit 22 of the bullet stopping embankment 2, and the detection results are displayed as first to third wear level display screens, respectively.

[0051] The first to third wear level detection processes are performed by the control unit 31 of the terminal 3. In any of the wear level indications, when a threshold value set for a consumable item is exceeded, the item is displayed in color, making it easy to recognize when it is time to replace the item.

[0052] [First wear detection] The first wear level detection will be described. In the first wear level detection, the control unit 31 of the terminal 3 uses the training plan stored in advance in the memory unit 32 and the cumulative number of hits up to that point for each component (target 11) to calculate the planned cumulative number of hits for each target over a certain period of time, and displays the first wear level display screen.

[0053] [Training planning table: Figure 6] First, a training plan table used in the first fatigue level detection process will be described with reference to Fig. 6. Fig. 6 is an explanatory diagram showing an example of the training plan table. As shown in FIG. 6, the training plan table stores, in association with the training number, the shooting number, training content, number of bullets used, and shooter information for each target, and is stored in the storage unit 32.

[0054] In the example of FIG. 6, the order of shooters (shooting order) and the number of bullets used for each of targets A to E are stored as a training plan for training number 1 (first training) on ​​July 1st. For example, it is planned that shooters A, E, I, ..., Q will each shoot 10 shots at target A in that order. In this example, target E is not used in the first training session. In other words, the control unit 31 of the terminal 3 manages, using the training plan table, the maximum number of bullets that are planned to hit each target 11 for each training session as the "number of bullets to be used."

[0055] [Cumulative number of hits table: Figure 7] Next, the cumulative landing number table will be described with reference to Fig. 7. Fig. 7 is an explanatory diagram showing an example of the cumulative landing number table. As shown in Fig. 7, the cumulative number of hits table stores the cumulative number of hits that have actually occurred up until the day before the training for each target 11. This is tallied based on the conventional number of hits per day shown in Fig. 14. The example in Fig. 7 shows the cumulative number of hits as of June 30, the day before the training day (July 1). The cumulative number of hits is the cumulative number of hits from the time each target 11 is replaced to a specific time, and in this shooting training system, it is used as a value that reflects the degree of consumption of consumables.

[0056] [First wear level display screen: Figure 8] Then, in the first wear level detection, the control unit 31 of the terminal 3 performs a process of calculating the planned cumulative number of hits before the start of training. The planned cumulative number of hits is a prediction of the cumulative number of hits at a specific time point in the future. Fig. 8 is an explanatory diagram showing an example of the first wear level display screen. Note that Fig. 8 is explained as a display example, but the control unit 31 of the terminal 3 generates a table equivalent to Fig. 8 (expected cumulative number of hits table) and stores it in the storage unit 32, and performs display based on that table.

[0057] Specifically, based on the training plan table shown in FIG. 6 and the cumulative number of hits table shown in FIG. 7, the control unit 31 adds the planned number of hits that would occur if all the bullets used in each training were to hit, to the cumulative number of hits up to that point, to calculate the planned cumulative number of hits after each training, and displays it as a list as the first wear level display screen. The number of rounds used during training, shown on the left side of Figure 8, corresponds to the planned number of hits.

[0058] In the example of FIG. 8, in the first training on July 1, the training plan of FIG. 6 indicates that a maximum of 100 shots will hit each of targets A to D. Then, the control unit 31 adds the planned number of impacts (100 shots) for the training with training number 1 (first training) to the cumulative number of impacts up to the day before the training shown in Figure 7 (7,820 shots for target A), and stores the planned cumulative number of impacts after the training, 7,920 shots, in the planned cumulative number of impacts table. The same calculation is performed for targets B to E.

[0059] Furthermore, for the second training on July 1st, the control unit 31 adds the planned cumulative number of hits in the previous training (first training) to the planned number of hits in the test (second training) to calculate the planned cumulative number of hits up to the second training on July 1st. Similarly, the planned cumulative number of hits up to the third training on July 7 is calculated and stored in the planned cumulative number of hits table.

[0060] Then, the control unit 31 causes the display unit 33 to display the first wear level display screen shown in FIG. 8 based on the expected cumulative number of landing bullets table. At that time, the control unit 31 compares the planned cumulative number of hits of each target 11 with the number of bullets (first threshold) that is set in advance for the target 11, and if the planned cumulative number of hits exceeds the number of bullets that can be used, displays the display area of ​​the planned cumulative number of hits in the most conspicuous color, for example, red (first color). Instead of coloring the area, characters may be displayed in color. In FIG. 8, the parts colored in red have numbers written inside them in white.

[0061] In other words, when the estimated cumulative number of hits on the first wear level display screen turns red, this indicates that the target 11 needs to be replaced. In the example of Figure 8, when the third training session on July 1st ends, the planned cumulative number of hits on target A will turn red, indicating that the number of hits will exceed the serviceable number of 8,000 rounds.

[0062] This display will allow maintenance personnel to recognize that target A will require replacement before the start of training on July 1 or after the end of the second training, and will allow them to carry out the replacement work, preventing the use of components that exceed their service life.

[0063] Furthermore, when the expected cumulative number of hits exceeds the first threshold, the control unit 31 displays an alarm message in a pop-up message such as "There is a component to be replaced." This makes it possible to reliably notify the person in charge that replacement is necessary.

[0064] Furthermore, in order to call attention even if the expected cumulative number of hits is within the range of the usable number of bullets, the control unit 31 sets a second threshold value and a third threshold value, and when the expected cumulative number of hits exceeds each threshold value, the first wear level display screen displays each of the threshold values ​​in a different color. For example, if the second threshold is exceeded, it is displayed in orange (second color), and if the third threshold is exceeded, it is displayed in yellow (third color). The values ​​of the respective thresholds are in the order of first threshold>second threshold>third threshold.

[0065] As a result, when the area for the expected cumulative number of hits is displayed in orange on the first wear level display screen, the training manager or maintenance staff can recognize that the time for replacement is approaching, and when it is displayed in yellow, they can take action such as beginning preparations for replacement. In the example of Figure 8, it can be seen that target B is nearing the time to replace it.

[0066] The third threshold value can also be set in anticipation of the procurement period of consumables. For example, by creating a training plan for the long term and setting the third threshold value to a value that takes into account the inventory quantity of each consumable item and the number of days from order to delivery, it is possible to order consumables in a way that prevents stockouts.

[0067] [Second wear detection] Next, the second method of detecting wear and tear in the present shooting training system will be described. The target 11 may be subject to a concentration of bullets at its center, and even if the cumulative number of bullets that have hit the target 11 as a whole has not reached its usable number of bullets, some parts may be severely damaged, increasing the possibility of false detection. The second wear level detection is for detecting such a portion that is highly worn out even if it is only a small portion.

[0068] In the second wear level detection, the control unit 31 of the terminal 3 calculates the cumulative number of hit bullets for each area into which the target 11 is virtually divided into a mesh and compares it with a fourth threshold value, generates a second wear level display screen that lists the wear level of each area, stores it in the memory unit 32, and displays and outputs the second wear level display screen in response to instructions from the operation unit 35.

[0069] [Subdivision of Target 11: Figure 9] The subdivision of the target 11 will be described with reference to Fig. 9. Fig. 9 is an explanatory diagram showing the subdivision of the target 11. As shown in Fig. 9, the control unit 31 divides the target 11 into a mesh shape vertically and horizontally on the screen where the image of the target 11 is displayed on the display unit 33, and holds information on the arrangement of each area and coordinates for identifying each area. In the example of Fig. 9, the entire target 11 is divided into 100 areas in a 10 x 10 matrix from (0,0) to (9,9). In FIG. 9, the image of the target displayed by the projector 13 is also shown superimposed.

[0070] Furthermore, control unit 31 stores information on the impact position from impact position detection sensor 12 and the coordinates of each area of ​​target 11 in association with each other. Then, when information on the impact position is input from impact position detection sensor 12, it identifies which area of ​​target 11 the bullet has impacted on, and adds it to the cumulative number of impacts for that area and stores it. In other words, in the second wear level detection, the cumulative number of impacts is managed for each area into which target 11 is divided.

[0071] Furthermore, the control unit 31 compares the cumulative number of hits in each area with a fourth threshold value, which is the upper limit of the cumulative number of hits for the area, and if the fourth threshold value is exceeded, the control unit 31 displays the area in question in a color, for example, red, on the second wear level display screen.

[0072] The fourth threshold is set to a value smaller than the first threshold, which is the number of bullets that the entire target 11 can withstand. Here, the first threshold is set to 8,000 bullets, whereas the fourth threshold is set to 4,000 bullets. Furthermore, fifth and sixth thresholds smaller than the fourth threshold may be set, and when these thresholds are exceeded, the degree of wear may be displayed in different colors to indicate the degree of wear in stages.

[0073] [Second wear level display screen: Figure 10] The second wear level display screen will be described with reference to Fig. 10. Fig. 10 is an explanatory diagram showing an example of the second wear level display screen. Note that Fig. 10 will be described as an example of display, but the control unit 31 of the terminal 3 generates a table equivalent to Fig. 10 (area cumulative bullet impact number table) and stores it in the storage unit 32, and performs display based on the table.

[0074] As shown in FIG. 10, the second wear level display screen displays the coordinates of each area divided into mesh-like areas and the cumulative number of bullets that have hit the area up to that point in time. In the example of FIG. 7, it can be seen that the bullets are concentrated near the center of the target shown in FIG. 6, and that the bullets only landed in the areas (4,4), (4,5), (5,4), and (5,5). And since 4002 bullets hit area (4,4), exceeding the fourth threshold (4000 bullets), that area is displayed in red.

[0075] In this way, in this shooting training system, the second wear detection can detect and clearly indicate wear that may cause a false positive, even if it is only a partial wear that cannot be detected by the first wear detection, which targets the entire target, and a maintenance technician can replace the target 11.

[0076] [Third wear detection] Next, the third wear level detection will be described. The third wear level detection is to detect the wear level of the bullet barrier 2 installed behind the target 11. A plurality of bullet stopping units 22 are attached in a matrix on the front surface of the bullet stopping embankment 2, and each bullet stopping unit 22 can be replaced individually.

[0077] The control unit 31 of the terminal 3 calculates the estimated cumulative number of hits for each stationary unit 22, generates a third wear level display screen that lists the wear level of each stationary unit 22, stores it in the memory unit 32, and displays the third wear level display screen in response to an instruction.

[0078] [Example of placement of the bullet stopping unit 22: Figure 11] An example of the arrangement of the bullet stopping units 22 in the bullet stopping embankment 2 and an image of the impact of bullets will be described with reference to Fig. 11. Fig. 11 is an explanatory diagram showing an example of the arrangement of the bullet stopping units 22 and an image of the impact of bullets. As shown in FIG. 11, the barrage 2 includes a plurality of barrage units (illustrated as barrages 1-1, 1-2, . . . 10-10 in the figure) 22 arranged in a matrix.

[0079] In the example of Fig. 11, the image of the target 11 placed in front of the bullet stopping wall 2 is shown by a dashed line, and a bullet that hits the target 11 will hit one of the bullet stopping units 22 of the bullet stopping wall 2 located behind it. Therefore, it is estimated that the bullet stopping unit 22 corresponding to the rear of the target shown by the dashed line will have a larger cumulative number of hits.

[0080] The control unit 31 of the terminal 3 of this shooting training system stores position information ((1-1), (1-2), ... (10-10)) corresponding to the placement of the bullet stopping units 22, in association with identification information of the bullet stopping units 22 installed at each position.

[0081] Furthermore, the control unit 31 stores information on the impact position from the impact position detection sensor 12 in association with information on the position of the bullet stopping unit 22 estimated from the impact position. In other words, when the impact position on the plane of the target 11 detected by the impact position detection sensor 12 is specified based on past training data and simulations, the control unit 31 estimates which bullet stopping unit 22 the bullet will hit in the bullet stopping embankment 2, and stores the information in advance in association with the information.

[0082] When information on the impact position is input from the impact position detection sensor 12, the information is added to the estimated cumulative number of impacts of the stopping unit 22 installed at the corresponding position and stored. In the third wear level detection, the estimated cumulative number of impacts is managed for each stopping unit 22.

[0083] In addition, the control unit 31 stores a seventh threshold value which is the number of bullets that can be used for the stopped bullet unit 22, and if there is a stopped bullet unit 22 whose estimated cumulative number of hit bullets exceeds the seventh threshold value, the stopped bullet unit 22 is displayed in color on the third wear level display screen. Furthermore, eighth and ninth thresholds smaller than the seventh threshold may be provided to display the degree of wear in stages using different colors.

[0084] [Third wear level display screen: Figure 12] The third wear level display screen will be described with reference to Fig. 12. Fig. 12 is an explanatory diagram showing an example of the third wear level display screen. Note that the control unit 31 generates a table equivalent to Fig. 12 (a table of the cumulative number of hit bullets per stationary unit) and stores it in the storage unit 32, and performs display based on the table.

[0085] As shown in FIG. 12, in response to an instruction from the operation unit 35, the control unit 31 causes the third consumption level display screen to be displayed. In this case, the stopped units (3-6) (listed by location information for convenience) and (8-7) are displayed in red because the estimated cumulative number of hit bullets exceeds the seventh threshold (10,000 bullets).

[0086] Also, the stopped units (2-6), (4-6), (7-6), (8-6), (9-6), and (8-8) are displayed in orange because their estimated cumulative number of hit bullets exceeds the eighth threshold (9,500 bullets) and is less than the seventh threshold. In FIG. 12, the orange area is shown surrounded by a frame. Also, stopped unit 22, which exceeds the ninth threshold (9,000 bullets) and is less than the eighth threshold, is displayed in yellow.

[0087] In this way, in this shooting training system, the third wear level detection is used to detect the wear level of the stopping wall 2 for each stopping unit 22 and display it in a list, so that stopping units 22 that are severely worn out can be replaced at the appropriate time without being overlooked, thereby improving safety.

[0088] In addition, since the estimated cumulative number of hits of each stationary unit 22 can be grasped by the third wear level display, it is possible to replace a stationary unit 22 that is close to the time for replacement with a stationary unit 22 with a smaller estimated cumulative number of hits.

[0089] In the example of Fig. 12, for example, the stopping units 22 displayed in orange may be replaced with stopping units (1-10), (3-1), (10-10), (10-1), etc. This is because the positions where these stopping units 22 are installed have a low possibility of being hit, and it is considered that the impact of installing a unit that is slightly worn out is small. After replacement, the previous estimated cumulative number of impacts for the stationary ammunition unit 22 is inherited and associated with the new position.

[0090] [Example of maintenance screen: Figure 13] Next, the maintenance screen of this shooting training system will be described with reference to Fig. 13. Fig. 13 is an explanatory diagram showing an example of the maintenance screen. In this shooting training system, it is possible to display a maintenance screen based on the first to third wear level detections described above, and Figure 13 shows a maintenance screen using the cumulative number of hits per target used in the first wear level detection (Figure 7) and the estimated cumulative number of hits per stopping unit 22 (stopping units 1-1, 1-2, ...) based on the third wear level detection (Figure 12).

[0091] The maintenance screen in Fig. 13 shows the acquisition date, number of useful bullets, number of bullets (cumulative number of bullets), and remaining number of useful bullets for each component name. The remaining number of useful bullets is calculated by the number of useful bullets - the cumulative number of bullets. If the number of bullets that can be used is less than the cumulative number of bullets that have landed, a negative value will be displayed.

[0092] For targets A to E, the cumulative number of hit bullets is compared with the first to third thresholds described above, and if it exceeds the first threshold (8000), the display area of ​​the remaining number of usable bullets is displayed in red, if it exceeds the second threshold (7500) and is equal to or less than the first threshold, it is displayed in orange, and if it exceeds the third threshold (7000) and is equal to or less than the second threshold, it is displayed in yellow. In Fig. 13, the areas displayed in red are white with numbers written inside.

[0093] In addition, for the stationary bullet unit 22, the estimated cumulative number of hit bullets is compared with the seventh to ninth thresholds described above, and if it exceeds the seventh threshold (10,000), it is displayed in red, if it exceeds the eighth threshold (9,500) and is equal to or less than the seventh threshold, it is displayed in orange, and if it exceeds the third threshold (9,000) and is equal to or less than the eighth threshold, it is displayed in yellow.

[0094] By displaying the list in this manner, it is possible to clearly identify and replace the targets 11 and ammunition units 22 that currently need to be replaced, and further, it is possible to know which targets 11 and ammunition units 22 are close to the time for replacement, and to prepare for their replacement.

[0095] [Effects of the embodiment] According to this shooting training system, the control unit 31 of the terminal 3, which acquires impact position information from the impact position detection sensor 12 and manages the number of impacts for each target 11, stores in the memory unit 32 in a training plan table the number of bullets used for each target 11 for multiple training sessions scheduled for a certain period of time in the future, and calculates the planned cumulative number of impacts for each target 11 for each scheduled training session based on the cumulative number of impacts for each target 11 up to the previous day and the number of bullets used in the training plan, and displays these in a list on the display unit 33. If the planned cumulative number of impacts exceeds a set threshold for the number of usable bullets, the display portion of the list that shows the planned cumulative number of impacts that exceeds the threshold is displayed in color. This allows maintenance personnel to recognize at a glance whether there are any targets 11 that need to be replaced within a certain period of time, and by knowing in advance when each target 11 should be replaced, the targets 11 can be replaced at the appropriate time, resulting in improved efficiency and safety of maintenance work and training.

[0096] Furthermore, according to this shooting training system, the control unit 31 calculates the cumulative number of hit bullets for each of a number of areas into which the entire target 11 is divided into a mesh pattern, and if there is an area where the cumulative number of hit bullets exceeds a specific threshold value that is smaller than the number of bullets that can be used for the entire target 11, an alarm regarding the replacement of the target 11 is displayed. Even if the number of bullets that can be used as a whole has not been reached, if there are severely damaged areas, such as near the center of the target 11, it is possible to urge the user to replace the target 11, which has the effect of preventing false detections and improving safety.

[0097] Furthermore, according to the present invention, the shooting training system is provided on the surface of the bullet stopping wall 2 installed behind the target, and stores information on a plurality of bullet stopping units 22, which are replacement units, corresponding to the impact positions on the target 11 and its surroundings, calculates an estimated cumulative number of impacts in each bullet stopping unit 22 based on the impact positions, and when the estimated cumulative number of impacts exceeds a threshold value for the number of bullets that can be used by the bullet stopping unit 22, displays an alarm regarding the replacement of the bullet stopping unit 22. This has the effect of alerting the user that there is a bullet stopping unit 22 that is likely to be damaged and encouraging the user to replace the bullet stopping unit 22, thereby improving safety. [Industrial Applicability]

[0098] The present invention is suitable for a shooting training system that can clearly notify the replacement time of consumables, enable replacement at the appropriate time, and improve the efficiency of maintenance work and shooting training, as well as the safety of training.
