Description

Technology Field

[0001] The present invention relates to a safety system for a shooting range, and more specifically, to a safety management system for a shooting range using bulletproof helmets and bulletproof vests for shooting personnel to prevent safety accidents occurring inside the shooting range during shooting training.

[0002] More specifically, the present invention relates to a shooting range safety management system configured to manage the safety of shooters by enabling shooters to clearly hear the manager's voice at the shooting range, and by detecting the shooter's risk exposure rate displayed on the screen of a video module within the shooting range through a video module that detects access to a danger area, thereby determining the shooter's risk status and varying the management control method according to the determined risk exposure rate. Background Technology

[0003] The present invention relates to a shooting range safety management system, and more specifically, to a shooting range firearms accident prevention system that enhances the delivery of shooting instruction to shooters during firearms training within a shooting range and can prevent firearms accidents occurring during shooting training.

[0004] Recently, at live-fire shooting ranges where live ammunition is used for practice, there is a problem where instruction from instructors or managers is not properly conveyed to shooters while they are firing due to external noise, resulting in reduced concentration and effectiveness of the training.

[0005] Therefore, safety accidents within shooting ranges are always a problem due to the increase in accidental shootings that go beyond the control of instructors or supervisors.

[0007] Furthermore, at shooting ranges, safety accidents such as gunshot injuries are occurring as shooters unwittingly move into dangerous areas, escaping the control of instructors and others in unfamiliar environments.

[0008] Safety accidents at shooting ranges where soldiers, police, and reservists conduct live-fire training can lead to major casualties, requiring heightened caution. Firearms accidents occur in various forms at these ranges, ranging from accidental discharges caused by shooter negligence to shootings intended to harm others or oneself.

[0009] Conventional shooting ranges use devices such as locking hooks to restrict the movement of firearms or securing them to the firing lanes to prevent safety accidents.

[0010] However, this physical management method cannot completely control accidents occurring during the movement of firearms before and after shooting. Furthermore, while it relies on safety training and deploying a large number of personnel for thorough control, there are no separate countermeasures in place.

[0012] Regarding these problems, if we look at the prior art, the prior art document KR 10-2017-0022365 (Title of invention: Shooting range control system) discloses a shooting control system comprising a gun position determiner that detects the position and direction of a gun to prevent gun accidents at a shooting range, a system controller that outputs a control signal calculated based on the position and direction information of the gun received from the gun position determiner, and a control stick controller that receives the control signal output from the system controller and blocks or allows firing of the gun according to the control signal.

[0013] However, the content disclosed in the prior art can only prevent accidents in a part of firearm accidents by detecting only the direction of the firearm. Furthermore, since a short-range wireless reader and a short-range wireless tag are used when detecting the direction of the firearm, detailed direction values ​​for the direction of the firearm cannot be obtained, and there is a problem that if the shooter turns the direction of the firearm even slightly, it exceeds the identification range by the short-range wireless tag and a false alarm occurs.

[0015] Recently, numerous safety devices are being researched to prevent firearm accidents during shooting training. For example, technologies involving the installation of wireless communication devices on firearms or magazines for control by a central control system are currently under study. However, such methods are costly and cannot be considered direct safety devices within the shooting range. Prior art literature

[0016] Patent Document 1: Korean Published Patent Application No. 10-2017-0022365 (Publication Date: March 2, 2017) Patent Document 2: Korean Published Patent Application No. 10-2024-0143253 (Publication Date: October 2, 2024) Patent Document 3: Korean Utility Model Publication No. 20-2023-0001521 (Publication Date: July 28, 2023) Patent Document 4: Korean Registered Patent Publication No. 10-1589450 (Publication Date: January 29, 2016) The problem to be solved

[0017] To solve the above problems, the present invention aims to provide a shooting range safety management system configured so that a shooter wearing a bulletproof helmet at the shooting range can clearly hear the voice of a manager in order to manage the safety of the shooter.

[0018] In addition, the purpose is to provide a shooting range safety management system configured to detect the shooter's risk exposure rate displayed on the screen of a video module within the shooting range through a video module that detects access to a danger area within the shooting range, determine the shooter's risk status based on this, and transmit an alarm signal to the bulletproof vest worn by the shooter according to the determined risk exposure rate. means of solving the problem

[0019] To achieve the above objective, the present invention provides a shooting range safety management system using a bulletproof helmet and a bulletproof vest, characterized by comprising: a video module installed in a shooting range to detect a shooter’s approach to a danger zone within the shooting range; a safety control device connected to the video module that determines the shooter’s danger state by comparing the shooter’s danger exposure rate with a preset danger exposure rate based on the shooter’s danger exposure rate for the entire screen of the video module and generates a control signal; a voice control device mounted on a frame structure installed in the shooting space where shooters are positioned during shooting, which transmits a manager’s microphone voice to the shooter; a bulletproof helmet worn by shooters, which has a voice conversion device installed inside with a telecoil inserted that is linked to the voice control device; and a bulletproof vest for shooters that is equipped with a communication module terminal inside, communicates with the safety control device through the communication module terminal, and is configured to generate an alarm upon receiving a control signal output from the safety control device.

[0021] The voice control device comprises: an induction amplifier connected to a speaker connected to a microphone via a sound source line, which converts a voice signal into current and amplifies and outputs the current upon receiving a sound source generated from the speaker; and a closed loop connected to the induction amplifier via a closed-loop conductor and disposed in the frame structure, wherein the current output from the induction amplifier flows along the closed-loop conductor to form a closed-loop zone. In the space of the frame structure where the closed-loop zone is formed, the gunner is configured to clearly perceive the sound source generated from the speaker through the voice conversion device.

[0023] The risk exposure rate of the shooter of the above safety control device is characterized by dividing the entire screen displayed through the image module into segmented screens at regular intervals to form segmented screens, and calculating the sum of the recognized body areas of the shooter by applying different weights to each segmented screen.

[0024] The above split screen is configured to form multiple split screens by dividing the entire screen displayed through the video module into vertical sections at regular intervals.

[0026] The above safety control device comprises: a risk exposure rate setting unit configured to subdivide and set the shooter's risk exposure rate in stages; a reading unit that calculates the total area as the risk exposure rate by applying different weights to the recognized body area of ​​the shot for each divided screen, which divides the entire screen of the image module at regular intervals; and an operation control unit that receives the risk exposure rate set by the setting unit and, upon receiving a signal regarding the risk exposure rate calculated by the reading unit, compares it with the set risk exposure rate to generate a control signal among a vibration signal, a sound signal, and a visual signal in stages and transmits it to the communication module terminal of the bulletproof vest.

[0027] Additionally, the safety control device comprises: an identification number recognition unit that receives a wireless signal including identification information of a communication module terminal mounted on the bulletproof vest for each shooter; and a bulletproof vest identification number storage unit that stores identification information of each communication module terminal of the bulletproof vest. The identification number recognition unit is configured to transmit a trigger signal to the operation control unit so that when the received identification number is included in the identification number stored in the bulletproof vest identification number storage unit, a control signal generated by the operation control unit is transmitted to the communication module terminal having the identification number. Effects of the invention

[0028] In order to manage the safety of shooters, the present invention is configured so that the manager's voice can be clearly heard by a shooter wearing a bulletproof helmet at the shooting range through a voice control device, thereby enabling the establishment of a shooting range safety management system with enhanced manager control.

[0029] In addition, a shooting range safety management system can be established by utilizing a video module that detects access to a danger zone within the shooting range, detecting the shooter's risk exposure rate displayed on the video module's screen via a safety control device to determine the shooter's risk status, and transmitting an alarm signal to the bulletproof vest worn by the shooter based on the determined risk exposure rate, thereby enabling the shooter to immediately assess their level of risk even while moving around the danger zone.

[0030] In addition, by configuring the operation control unit to transmit a control signal to the shooter's bulletproof vest only when the identification number of the shooter's communication module terminal received by the identification number recognition unit of the safety control device is included in the identification number stored in the bulletproof vest identification number storage unit, it is possible to construct a shooting range safety management system that operates only for a shooter wearing a bulletproof vest.

Specific details for implementing the invention

[0032] Hereinafter, embodiments of a shooting range safety management system using a bulletproof helmet and bulletproof vest according to the present invention will be described in detail with reference to the attached drawings.

[0033] The present invention relates to a safety management system for supporting safety at a shooting range.

[0034] FIG. 2 is a configuration diagram of a shooting range safety management system using a bulletproof helmet and a voice control device according to the present invention.

[0035] Referring to the illustration, the shooting range of the present invention comprises a frame structure installed in the shooting space where shooters are positioned during shooting.

[0036] In addition, a video module (200) is configured to be installed on the side of the shooting range and to detect the shooter's approach to the danger zone within the shooting range.

[0037] In the shooting range, there is a dangerous area where there is a risk of accidents occurring if shooters enter, and the video module (200) that enters this dangerous area monitors whether there is movement of shooters into this dangerous area.

[0038] In addition, the present invention comprises a safety control device (300) that is connected to an image module (200) and generates a control signal by determining the shooter's dangerous state through the shooter's risk exposure rate for the entire screen of the image module and comparing it with a preset risk exposure rate. The detailed operating principle of the safety control device (300) will be described later.

[0040] In addition, the present invention is configured with a voice control device (500) mounted on a frame structure installed in a shooting space to transmit the manager's microphone voice to the shooters, and the role of the voice control device (500) is to accurately transmit the microphone voice of the shooting manager or shooting instructor to the shooters.

[0041] Shooters receiving shooting training at the shooting range of the present invention wear a bulletproof helmet (400), and a voice conversion device (410) with a telecoil inserted that is linked to a voice control device (500) is installed inside the bulletproof helmet (400).

[0043] The method of linking the voice control device (500) and the bulletproof helmet (400) is explained as follows.

[0044] Figure 3 is a drawing of a voice converter including a telecoil of the present invention mounted on a shooter's bulletproof helmet.

[0045] As illustrated in FIGS. 2 and 3, a voice control device (500) is configured to be mounted on a frame structure installed in a shooting space and to transmit the manager's microphone voice to the shooter, and the shooter wears a bulletproof helmet (400) that communicates with the voice control device (500) and performs shooting training inside the frame structure.

[0046] A voice converter (410) is configured on the inner side of the bulletproof helmet (400) of the present invention so as to be inserted into the ear of the shooter wearing the bulletproof helmet while in direct contact with the shooter's ear.

[0047] Therefore, when the shooter wears the bulletproof helmet (400), the voice converter (410) comes into direct contact with the shooter's ear, and the shooter can clearly hear the voice of the manager or assistant transmitted from the voice converter (410).

[0048] The voice converter (410) is configured to include a telecoil (T-coil), and the bulletproof helmet may be configured with a charging unit (not shown) that supplies power to the voice converter (410).

[0050] Referring to FIG. 2, the configuration of the voice control device (500) is such that the voice control device (500) is configured to be linked with a voice converter (410) having a telecoil inserted therein, which is mounted on a bulletproof helmet (400) worn by a shooter.

[0051] The voice control device (500) is configured with a speaker (510) connected to a microphone used during shooting training by an administrator or shooting instructor.

[0052] Additionally, an induction amplifier (530) is configured to be connected to a speaker (510) via a sound source line, and to convert a voice signal into an electric current and amplify and output the electric current when it receives a sound source generated from the speaker (510).

[0053] That is, when the voice of an administrator or assistant is generated from the speaker (510), the induction amplifier (530) receives the generated sound source through the sound source line (520), converts the received voice signal into an electric current, amplifies it, and outputs it.

[0054] In addition, a closed loop (540) is configured to be positioned above the firing space and connected to an induction amplifier (530) by a closed loop wire, so that the current amplified and output from the induction amplifier (530) flows along the closed loop wire to form a closed loop zone.

[0055] The above closed loop (540) can be installed so as to be positioned on the upper side of a frame structure installed in a firing space.

[0056] In reality, shooting ranges are quite noisy. As a result, the voices of managers or instructors are mixed with the ambient noise and output through microphones, making them barely audible to the shooters. Consequently, managers' control over shooting personnel becomes inadequate, and due to factors such as shooters' lack of awareness regarding firearm usage, gun accidents and dangerous situations occur frequently.

[0057] When the current output through the induction amplifier (530) flows through the closed loop (540), magnetic flux, that is, a magnetic signal, is generated around the closed loop wire.

[0058] When a shooter is in the closed-loop zone of a frame structure installed in the shooting space, the telecoil configured in the voice converter (410) of the bulletproof helmet (400) converts the magnetic signal into a voice signal, which is an electric signal, by means of electromagnetic induction, thereby restoring the sound source generated from the microphone (510) and transmitting it to the shooter's ear.

[0059] That is, since the restored sound source is a sound source generated from a microphone (510) that is not mixed with any noise or sounds from the surrounding shooting space, a shooter wearing a bulletproof helmet (400) in the closed-loop zone of the frame structure installed in the shooting space can clearly perceive the sound source generated from the microphone (510) through the voice converter (410).

[0061] In addition, shooters receiving shooting training at the shooting range of the present invention wear a bulletproof vest (100) equipped with a communication module terminal (120) inside and connected to a safety control device (300) through the communication module terminal (120).

[0062] Accordingly, when the shooter receives a control signal output from the safety control device (300) when the shooter intrudes into the danger zone, the bulletproof vest (100) is configured to trigger an alarm.

[0063] Inside the bulletproof vest (100), a communication module terminal (120), a battery (110), a visual signal LED, a sound sensor, a vibration sensor, etc. are configured, and when a control signal output from the safety control device (300) is received, vibration, sound, or light is generated immediately according to the control signal.

[0065] FIG. 4 is an operational configuration diagram between a bulletproof vest and a safety control device connected via communication according to the present invention. FIG. 5 and 6 are diagrams illustrating the process of setting the shooter's risk exposure rate in stages through the setting unit of the safety control device according to the present invention. FIG. 7 is a diagram illustrating the process of calculating the shooter's risk exposure rate through the reading unit of the safety control device according to the present invention.

[0066] Referring to the illustration in FIG. 5, the shooting range of the present invention is configured with an image module (200) that detects when a shooter moves into a danger zone.

[0067] In addition, a safety control device (300) connected to a video module (200) is configured in the shooting range.

[0068] The safety control device (300) is configured to generate a control signal by comparing the risk exposure rate of the shooter with the preset risk exposure rate for the entire screen of the video module (200).

[0070] Referring to FIGS. 4, 6, and 7, the safety control device (300) is configured with a risk exposure rate setting unit (320) configured to subdivide and set the risk exposure rate of the shooter in stages.

[0071] The risk exposure rate set in the setting unit (320) is not simply the absolute area of ​​the shooter's body occupying the entire screen of the video module (200), but rather a risk exposure rate calculated as a relative area that considers the risk level according to the shooter's position.

[0073] To this end, the safety control device (300) is configured with a reading unit (330) that calculates the sum of the body areas of the recognized shooter, each divided into segments with different weights for each segment of the entire screen of the image module (200), as the risk exposure rate.

[0074] Additionally, the safety control device (300) is configured with an operation control unit (340), into which a risk exposure rate set in the setting unit (320) is input, and when a signal regarding the risk exposure rate calculated by the reading unit (330) is received, it is compared with the risk exposure rate set in the setting unit (320) and configured to trigger an alarm on the bulletproof vest (100) worn by the shooter.

[0075] To elaborate, when the operation control unit (340) receives a signal regarding the risk exposure rate calculated by the reading unit (330), it compares this with the risk exposure rate preset in the setting unit (320) and generates a control signal among a vibration signal, a sound signal, and a visual signal in stages, and transmits it to the communication module terminal (120) of the bulletproof vest (100) to provide an alarm to a shooter approaching the danger area.

[0077] Additionally, the safety control device (300) is configured with an identification number recognition unit (310) that receives a wireless signal containing identification information of a communication module terminal (120) mounted on a bulletproof vest (100) for each shooter, and a bulletproof vest identification number storage unit (350) that stores identification information of each communication module terminal (120) of the bulletproof vest.

[0078] Generally, at a shooting range, there are not only shooters conducting shooting training, but also managers and others who access the hazardous areas of the shooting range to perform general tasks such as managing the shooting range.

[0079] The identification number recognition unit (310) transmits a trigger signal to the operation control unit (340) so that, only in this case, the control signal generated by the operation control unit (340) is transmitted to the communication module terminal (120) having the identification number when the identification number received from the communication module terminal (120) mounted on the bulletproof vest (100) of the shooter at the shooting range is included in the identification number stored in the bulletproof vest identification number storage unit (350).

[0080] That is, the control signal generated by the operation control unit (340) is transmitted to the shooter's bulletproof vest only when the identification number of the shooter's communication module terminal (120) received by the identification number recognition unit (310) of the safety control device (300) is included in the identification number stored in the bulletproof vest identification number storage unit (350), and the system is configured to operate only on the shooter wearing the bulletproof vest (100) and not on unnecessary personnel such as managers, thereby blocking power consumption caused by unnecessary operation, thus forming a shooting range safety management system.

[0082] Referring to FIGS. 5 and 6, this is a diagram illustrating the process of setting the risk exposure rate of a shooter in stages through the setting unit of the safety control device according to the present invention.

[0083] Referring to FIG. 5, the setting unit (320) of the safety control device (300) sets a risk exposure rate that takes into account the risk level according to the position of the shooter exposed on the entire screen of the video module (200) when the shooter enters the danger area of ​​the shooting range.

[0085] Referring to the illustration in FIG. 6, the setting unit (320) of the safety control device (300) transmits control signals of "vibration," "sound," and "visual" in stages according to the degree of entry of the shooter into the danger area. As previously described, the risk exposure rate set by the setting unit (320) does not simply mean the absolute area of ​​the shooter's body occupying the entire screen of the video module (200), but rather the risk exposure rate as a relative area that considers the risk level according to the shooter's position.

[0087] For example, as illustrated in FIG. 6, the setting unit (320) of the safety control device (300) sets a standard so that a "vibration" control signal is generated when the shooter's risk exposure rate is 16% or higher, and likewise sets a standard so that a "sound" control signal is generated when the shooter's risk exposure rate is 30% or higher, and sets a standard so that a "visual" control signal is generated when the shooter's risk exposure rate is 5% or higher.

[0089] FIG. 7 is a diagram illustrating the process of calculating the risk exposure rate of a shooter through the reading unit of a safety control device according to the present invention.

[0090] Referring to the illustration, the configuration for reading by the reading unit (330) of the safety control device (300) is such that a plurality of divided screens are formed by dividing the entire screen displayed through the image module (200) into equal intervals in the vertical direction.

[0091] Specifically, in the reading unit (330) of the safety control device (300), the risk exposure rate of the shooter is configured to be calculated by dividing the entire screen of the image module (200) into segmented screens at regular intervals and applying different weights to the recognized body area of ​​the shooter for each segmented screen.

[0093] Referring to the illustration in FIG. 7, when a shooter enters the danger zone of the shooting range, if the direction of the shooter's movement is from the "A" split screen to the "C" split screen when viewed in the full screen displayed on the video module (200), the area of ​​the shooter's body exposed in the full screen displayed on the video module (200) may vary depending on the shooter's movement.

[0094] Looking at the method of calculating the risk exposure rate of the reading unit (330), instead of calculating the absolute size of the area of ​​the shooter's body displayed on the full screen of the image module (200), more weight is given to the "B" split screen than to the "A" split screen, and likewise, more weight is given to the "C" split screen than to the "B" split screen.

[0095] Therefore, the risk exposure rate calculated by the reading unit (330) may differ depending on which split screen the shooter's body position spans, even if the absolute area is the same.

[0097] In addition, depending on which part of the divided screen the position of the shooter's body overlaps more, there may be cases where the absolute area of ​​the shooter's body relative to the full screen of the image module (200) is large, but the risk exposure rate is smaller than in cases where the absolute area of ​​the shooter's body is small. In other words, the reading unit (330) determines the current risk level of the shooter by giving more weight as the position of the shooter entering the danger area of ​​the shooting range goes deeper into the danger area.

[0099] The amplifier (330a) configured in the reading unit (330), which is connected to each of the split screens of the video module (200), sets a different weight for each split screen.

[0100] To elaborate, it is configured to assign a greater weight to the shooter's body area recognized in the "B" split screen than to the weight to the shooter's body area recognized in the "A" split screen, and similarly, to assign a greater weight to the shooter's body area recognized in the "C" split screen than to the "B" split screen.

[0101] The calculation unit (330b) of the reading unit (300) calculates the risk exposure rate by applying a sum of body areas of the recognized shooter with different weights for each divided screen.

[0103] Looking at the operation control unit (340), the risk exposure rate set in the setting unit (320) is input, and when the signal regarding the risk exposure rate calculated by the reading unit (320) is received, it is compared with the risk exposure rate set in the setting unit (320) and generates one of the control signals: a vibration control signal, a sound control signal, or a visual control signal using an LED.

[0104] More specifically, the operation control unit (340) is configured with a comparator (340a) that compares the risk exposure rate set in the setting unit (320) with the risk exposure rate calculated in the reading unit (320), and a transmitter (340c) that generates and transmits one of a control signal, a sound control signal, or a visual control signal using an LED when the result analyzed through the comparator is greater than or equal to the reference range of each set risk exposure rate.

[0105] Additionally, the operation control unit (340) may include a timer (340b) that can set the duration of the warning sound or warning sound for a certain period of time.

[0106] More specifically, the timer (340b) can be set from 1 to 100,000 seconds, and when set to 1M, it is configured to continuously emit sound until a relevant person checks and takes action.
