Description

Technology Field

[0001] The present invention relates to a technical field for quantitatively evaluating the chemical protection performance of protective clothing using a human-mimicking mannequin, and more specifically, to a mannequin system for measuring real-time vapor and aerosol protection performance and a method for measuring the same, for evaluating the real-time protection performance of a protective clothing system in an environment where chemical substances in the form of vapor and aerosol are mixed. Background Technology

[0003] Generally, performance tests for protective clothing to evaluate human protection against chemical substances have been conducted by dressing a human-mimicking mannequin in the protective suit, exposing it to chemicals from the outside, and measuring the degree of internal contamination after a certain period of time.

[0004] While these existing testing methods have some utility in evaluating the barrier performance of protective clothing, they have limitations in that most human-mimicking mannequins are used in static conditions and fail to adequately reflect the dynamic motion of the actual human body or complex chemical environments.

[0005] Existing mannequin testing systems are primarily configured in a post-test manner, which measures the residual amount of contaminants adsorbed on the skin surface or collects and analyzes samples after the test is completed.

[0006] This method cannot observe the progression of contamination or the rate of penetration within the protective suit in real time, nor can it reflect changes in protective performance during testing.

[0007] Furthermore, conventional testing devices are structured to test vapor-phase chemicals and aerosol-phase particles separately using different equipment, making it difficult to simulate complex exposures (e.g., environments involving a mixture of hazardous gases and particulates) that occur in actual operational environments or disaster sites.

[0008] In other words, since the evaluation of vapor penetration and particle penetration were conducted separately, there was a problem in that cross-effects under the same conditions or composite blocking performance could not be accurately determined.

[0009] In addition, most existing mannequin systems are based on local sensors, so data could only be collected from certain parts of the mannequin (e.g., chest, abdomen, etc.).

[0010] Therefore, it was difficult to detect minute penetrations or leaks occurring in structurally vulnerable areas of the protective suit, such as seams, zippers, and joints, and there were limitations in quantitatively analyzing the spatial protection performance distribution across the entire mannequin.

[0011] Furthermore, conventional systems failed to account for changes in the fit of the protective suit due to human movement, fluctuations in internal air pressure, and changes in material tension.

[0012] In real-world environments, the joints of the protective suit may separate or micro-gaps may form as the wearer moves, creating pathways for chemical penetration; however, it was difficult to accurately reproduce this dynamical leakage phenomenon using conventional static testing methods.

[0013] In addition, existing evaluation systems lacked the capability for real-time analysis of measurement data, requiring a procedure to manually collect and analyze data after the test was completed.

[0014] Consequently, experimental efficiency was low, and it was difficult to provide immediate feedback on directions for improving protective suit performance.

[0015] Consequently, conventional protective clothing performance evaluation technology had structural limitations such as being centered on static testing, separating and measuring vapor and aerosols, relying on partial sensors, being unable to reflect motion, and non-real-time data processing.

[0016] Therefore, there is a need for an integrated mannequin system capable of simulating human movement in a real-world environment and quantitatively evaluating real-time protective performance by body part under conditions of complex chemical substances mixed with vapors and aerosols.

[0049] Specific details of other embodiments are included in "Specific details for implementing the invention" and the attached "drawings".

[0050] The advantages and / or features of the present invention and the methods for achieving them will become clear by referring to the various embodiments described below in detail together with the accompanying drawings.

[0051] However, it should be understood that the present invention is not limited to the configurations of each embodiment disclosed below, but may be implemented in various different forms, and that each embodiment disclosed in this specification is provided merely to make the disclosure of the present invention complete and to fully inform those skilled in the art of the scope of the present invention, and that the present invention is defined only by the scope of each claim of the claims. Effects of the invention

[0053] As such, according to the present invention, in order to quantitatively evaluate the chemical protection performance of a protective suit in real time, the existing testing method was a post-processing method in which samples were collected and analyzed after the test was completed. However, the present invention collects and analyzes data in real time from a vapor measurement sensor and an aerosol measurement sensor embedded inside a mannequin, thereby allowing the degree of chemical penetration into the protective suit to be immediately identified even during the test. Accordingly, changes in the barrier performance of the protective suit can be continuously observed on the time axis, and the initiation point of penetration and the location of leakage can be tracked in real time.

[0054] Furthermore, according to the present invention, in order to enable the integrated evaluation of protective performance in a complex threat environment involving vapors and aerosols, vapor-phase chemicals and aerosol-phase particles are controlled simultaneously or independently within a single system, and the penetration amount of each substance can be measured under the same test conditions. This eliminates the need to operate two types of test equipment separately as in the past, and allows for the precise reproduction of complex chemical exposure conditions in actual operational environments or industrial disaster sites, thereby providing the effect of enabling the evaluation of the comprehensive blocking capability and mutual influence of the protective suit.

[0055] In addition, according to the present invention, by equipping the arms, legs, and torso of a mannequin with driving modules to enable various movements such as walking, sitting, and arm swinging, it is possible to perform dynamic protective performance evaluation reflecting human movement conditions. This allows physical factors such as changes in the tightness of the protective suit, tensile deformation of the material, and widening of seam gaps that occur according to actual human movement to be reflected in the test, thereby enabling the quantitative analysis of the rate of degradation of blocking performance under dynamic conditions compared to static conditions of the protective suit. This has the effect of serving as a key basis for future structural design and material improvement of the protective suit.

[0056] In addition, according to the present invention, in order to provide design feedback through analysis of penetration vulnerability by area, individual data is collected from a plurality of sensors distributed in each part of the mannequin, allowing for the quantitative comparison of protective performance by detailed areas such as the head, chest, abdomen, limbs, seams, and zippers. Through this, vulnerable areas where chemical penetration occurs relatively frequently can be identified, and immediate feedback can be provided regarding the structural design, material selection, and sealing structure improvement of the protective suit.

[0057] In addition, according to the present invention, in order to enable real-time visualization and automatic analysis of measurement data, data collected through a sensor network is integrated and analyzed in real time by a central control module, and the amount of penetration for each part is visualized in a three-dimensional graphic form such as color, concentration, and time change. Through this, the tester can intuitively recognize the distribution of the overall protective performance, and since the performance index (report index) is automatically calculated immediately after the test ends, the test efficiency can be significantly improved.

[0058] In addition, according to the present invention, in order to improve the reproducibility and reliability of the test, it is configured to perform multiple repeated tests under the same test conditions using an automatic control method. By minimizing variable factors caused by experimenter intervention, deviations between test results are reduced, and the concentration, flow rate, exposure time, etc. of the chemical substance can be precisely controlled, thereby having the effect of simultaneously ensuring test reproducibility and data reliability.

[0059] Furthermore, according to the present invention, in order to have the potential for expansion into an international standardized testing system, it is applicable not only to testing of CBRN protection systems in the defense sector but also to various application fields such as industrial safety and health, environmental disaster response, and biological aerosol blocking evaluation, and has the effect of being utilized in establishing criteria for international testing standards (ISO, ASTM, MIL-STD, etc.).

[0077] FIG. 1 is a block diagram showing the configuration of a mannequin system for measuring real-time steam and aerosol protection performance according to one embodiment of the present invention.

[0078] Referring to FIG. 1, a mannequin system (1000) for measuring real-time steam and aerosol protection performance according to one embodiment of the present invention includes a mannequin body (100) and a server (200).

[0079] The mannequin body (100) includes a plurality of sensor modules (110), and the server (200) includes a data processing module (210) and an operation control module (220).

[0080] The mannequin body (100) is modeled after the human body.

[0081] Such a mannequin body (100) can be configured to allow for the evaluation of protection performance in both a stationary state and an operating state.

[0082] The mannequin body (100) may include a plurality of joints and actuators.

[0083] Depending on the control of these actuators, it can be configured to implement one or more movements among walking, sitting, and limb movements.

[0084] In addition, a plurality of sensor modules (110) are provided inside the mannequin body (100) to measure the concentration of vapor or aerosol penetrating into the protective suit in real time.

[0085] These multiple sensor modules (110) may be distributed and positioned on the head, chest, abdomen, arms, and legs of the mannequin body (100), respectively, to independently measure the vapor or aerosol penetration concentration for each area.

[0086] Additionally, the plurality of sensor modules (110) may include a steam sensor and a particle sensor.

[0087] The vapor sensor detects the vapor concentration.

[0088] Particle sensors detect the concentration or number of aerosol particles.

[0089] Such vapor sensors and particle sensors can be placed in the same area or adjacent areas.

[0090] Meanwhile, the data processing module (210) of the server (200) collects and analyzes data collected from multiple sensor modules (110) in real time to calculate the protective performance of the protective suit.

[0091] This data processing module (210) may include a visualization interface that visualizes data collected from a plurality of sensor modules (110) in real time in conjunction with time and location information.

[0092] This visualization interface can be configured to display the protective performance of each part on a three-dimensional model of the mannequin body as a color or density map.

[0093] Additionally, the data processing module (210) may be configured to analyze each protective performance independently or simultaneously under steam-only test, aerosol-only test, and combined test conditions in which steam and aerosol are mixed.

[0094] The data processing module (210) can be configured to identify penetration-vulnerable areas of the protective suit using measurement data for each part and to generate a protective performance distribution map for each part.

[0095] Meanwhile, the operation control module (220) of the server (200) implements the operation of the Matekin main body (110).

[0097] To explain in more detail, the present embodiment relates to a mannequin system for measuring real-time vapor and aerosol protection performance, wherein a plurality of sensor modules (110) are placed inside a mannequin body (100) that mimics the shape of a human body to detect concentration information of vapor or aerosol penetrating into a protective suit in real time, and a data processing module (210) equipped with an external server (200) or control device collects and analyzes the detection data detected by the plurality of sensor modules (110) to quantitatively calculate the protective performance of the protective suit, and if necessary, switches the stopped state or operating state of the mannequin body (100) through an operation control module (220) to compare and evaluate the protective performance under static or dynamic conditions.

[0098] FIG. 1 illustrates a schematic configuration of a system according to one embodiment of the present invention.

[0099] A plurality of sensor modules (110) are provided inside the mannequin body (100).

[0100] The server (200) includes a data processing module (210) and an operation control module (220), and the mannequin body (100) and the server (200) transmit and receive signals through a wired / wireless communication unit.

[0101] The mannequin body (100) has an external shape that mimics the shape of a human body and an internal structure that includes at least a head, chest, abdomen, arms, legs, and joints.

[0102] The main body (100) is formed in accordance with standard human body dimensions so that changes in internal volume or shape when wearing a protective suit do not affect the actual measurement target, and may include a space for accommodating an actuator and a conduit for wiring or piping as needed.

[0103] The mannequin body (100) can be configured to allow for the evaluation of protection performance in both a stationary state and an operating state.

[0104] A plurality of sensor modules (110) may include a detection unit (not shown) for detecting the state of a chemical substance that has penetrated into the protective suit in real time.

[0105] In one embodiment, the sensor module (110) includes a vapor sensor (e.g., a detection element sensitive to a specific gas) and a particle sensor (an element that detects the number or concentration of aerosol particles), and may be placed in the same area or in adjacent areas.

[0106] The sensor module (110) is distributed at multiple locations such as the head, chest, abdomen, arms, and legs of the mannequin body (100) to independently measure the amount of penetration for each area.

[0107] The sensor module (110) may include basic signal processing functions such as signal amplification, filtering, and A / D conversion, and may include a time stamping function for time synchronization.

[0108] These functions can be performed on the sensor module (110) or server (200) side depending on the implementation of the mannequin body (100).

[0109] A data processing module (210) equipped in a server (200) or control device collects and analyzes data collected from a sensor module (110) in real time.

[0110] The data processing module (210) may include time and location mapping of collected data, validation and noise removal, calculation of protection performance indicators by part and condition, and output of a visualization interface of the results.

[0111] The visualization interface may be configured to display the protective performance of each part on a three-dimensional model of the mannequin body (100) as a color or density map.

[0112] However, this embodiment is not limited to the above-described notation method, and various forms such as contour lines, heat maps, and isosurfaces may be used.

[0113] The motion control module (220) is configured to implement one or more movements, such as walking, sitting, and limb movement, in conjunction with multiple joints or actuators of the mannequin body (100).

[0114] The operation control module (220) can set the operation scenario, cycle, speed, and operating range, and the set values ​​are linked with the data processing module (210) so that the operation conditions and measurement data are synchronized on the time axis.

[0115] The communication unit is a wired or wireless channel for transmitting and receiving data between the sensor module (110) and the server (200).

[0116] The communication method is selected according to the implementation environment, and the present invention is not limited to the communication method itself.

[0117] The typical operation of the system according to the present embodiment can be understood as follows.

[0118] Test preparation: The test suit is put on the mannequin body (100).

[0119] Setting Exposure Conditions: Select one or more of the vapor, aerosol, or mixture thereof as the chemical substance to be tested, and set external exposure conditions such as target concentration and flow rate.

[0120] Real-time detection: The sensor module (110) detects the concentration information of vapor or aerosol that has penetrated into the protective suit in real time and transmits it to the server (200) through the communication unit.

[0121] Action execution (optional): By driving the action control module (220) to perform actions such as walking, sitting, and limb movements, the protection performance under dynamic conditions is recorded.

[0122] Data processing and visualization: The data processing module (210) collects and analyzes the collected data to perform time and area mapping, calculates protection performance indicators for each area, and visualizes in real time as a color or density map on a 3D model.

[0123] Evaluation and Comparison: Based on the analysis results described above, the vulnerability of each part of the protective suit is identified, and the protective performance is relatively compared between vapor alone, aerosol alone, and mixed conditions.

[0124] Meanwhile, the detailed functions are as follows.

[0125] The distribution arrangement of the sensor module (110) can be designed to correspond to structurally vulnerable parts such as seams, zippers, bands, and joints.

[0126] Even with the same protective suit, the degree of tightness changes during operation, so real-time data by part directly reflects the leakage tendency of vulnerable areas.

[0127] The data processing module (210) collects vapor and aerosol data under the same test conditions and analyzes the protective performance under single conditions and mixed conditions independently or simultaneously.

[0128] At this time, differences in response time, capture characteristics, etc., caused by physical or chemical differences of each medium can be corrected during the data preprocessing stage.

[0129] The visualization interface intuitively displays the concentration change over time and the protective performance of each part on a three-dimensional model of the mannequin body (100).

[0130] The analysis results are compiled immediately upon the completion of the test and can be reported in the form of indicators by part, comparison tables by condition, and a list of vulnerable parts.

[0131] Next, various embodiments of the present invention will be described.

[0132] The first embodiment is an evaluation of stopping conditions.

[0133] The mannequin body (100) is maintained in a stationary state, and sensor modules (110) are placed in the head, chest, abdomen, arms, and legs, respectively.

[0134] External exposure is set to vapor or aerosol of a predetermined concentration, and the data processing module (210) records and visualizes the time change of the amount of penetration by site for a certain period of time.

[0135] The results are used to evaluate the static blocking performance of protective clothing.

[0136] The second embodiment is an evaluation of operating conditions.

[0137] Walking or limb movements are performed periodically through the motion control module (220).

[0138] The operation cycle and operating range are set according to the purpose of the test, and the data processing module (210) distinguishes between the operating section and the non-operating section to analyze the relative change in protection performance.

[0139] Through this, information about dynamic leakage can be obtained.

[0140] The third embodiment is a comparison of complex conditions.

[0141] Three conditions—vapor alone, aerosol alone, and a mixture of vapor and aerosol—are performed sequentially under the same external conditions.

[0142] The data processing module (210) compares the indicators calculated for each condition to evaluate the total protection performance under mutual influence and complex conditions.

[0143] The following describes variations of the present invention.

[0144] The above description is merely an example, and the present invention is not limited to the following.

[0145] In the first variant, the specific sensor type, detection method, attachment method, and number of distributions of the sensor module (110) may be changed according to the purpose of the test.

[0146] In the second variant, the analysis technique, visualization method, and indicator calculation formula of the data processing module (210) may be adopted in various ways within the scope of providing equivalent functions.

[0147] In the third variant, the driver arrangement, control method, and operation scenario of the operation control module (220) can be replaced with equivalents.

[0148] In the fourth variant, the wired / wireless method, protocol, and security level of the communication unit can be selected according to the system configuration.

[0149] As such, according to the present embodiment, real-time quantitative evaluation, integrated vapor and aerosol testing, motion-reflective evaluation, vulnerability analysis by part, and real-time visualization and automatic reporting are possible, thereby overcoming the limitations of existing static or separate testing methods and providing direct supporting data for protective clothing design, improvement, and standardization testing.

[0151] FIG. 2 is a configuration diagram showing the mannequin body in a mannequin system for measuring real-time steam and aerosol protection performance according to one embodiment of the present invention.

[0152] Referring to FIG. 2, the structure of a mannequin body (100) is illustrated exemplarily in a mannequin system (1000) for measuring real-time steam and aerosol protection performance according to one embodiment of the present invention.

[0153] The left side of Fig. 2 shows an example of frame and sensor placement, and the right side shows an example of making a mannequin equipped with an outer shell.

[0154] Looking at the frame structure and shape alignment, the mannequin body (100) is largely composed of a frame that mimics the shape of a human body and an outer panel that covers the outside of the frame.

[0155] The frame is divided into multiple segments corresponding to the head, neck, chest, abdomen, pelvis, upper and lower limbs (arms, legs), feet, and hands, and joints capable of rotation or flexion are placed between each segment.

[0156] The dimensions of the frame are set based on standard anthropometric measurements (distinguishable by gender and height), and it is formed to maintain a uniform gap with the outer shell to minimize volumetric deformation when wearing the protective suit.

[0157] The joint part may be equipped with an actuator mounting seat for implementing movement as needed.

[0158] The frame may be formed from one or more of aluminum alloy, carbon fiber composite, and stainless steel to ensure lightweight and high rigidity, and the surface may be finished with anodizing, PVD coating, fluorine-based water-repellent coating, etc., considering corrosion reduction and ease of detoxification.

[0159] Cable or tube conduits for organizing and protecting wiring or piping are integrated into the frame, and quick connectors are provided on a segment-by-segment basis to enable rapid disassembly and assembly during maintenance.

[0160] Looking at the sensor placement and fixing structure, a plurality of sensor modules (110) for real-time detection of chemical substances that have penetrated into the protective suit are distributed and arranged in different parts inside the mannequin body (100).

[0161] In one embodiment, the sensor module (110) includes a steam sensor and a particle sensor, and is fixed through a sensor mount at the same location or an adjacent location.

[0162] The sensor mount can be directly attached to the frame or fastened to a boss structure provided on the inner side of the outer shell panel.

[0163] Each sensor module is formed with a low-profile housing to minimize airflow disturbance in the area, and the sensor intake and exhaust ports are equipped with a fine mesh or antifouling filter to prevent particle capture or re-contamination.

[0164] In addition, to suppress sensor response delay and crosstalk, the distance between adjacent sensors is maintained above a predetermined value, and if necessary, partition baffles are placed to reduce mixing of local volumes.

[0165] The sensor module (110) may include a time synchronization means for measurement reliability, which may be synchronized with a reference time on the server (200) side or implemented as a GNSS / network-based PTP (Precision Time Protocol), etc.

[0166] For ease of calibration, each part may further include a calibration port and a reference gas injection connector.

[0167] Looking at the design of the outer shell panels and joints, the outer shell panels serve as covers that embody the human body shape, and the divided panels are joined to the frame through the joints.

[0168] Gaskets for dustproof, light-blocking, and water-blocking functions may be provided at the joints, and detachable fasteners (e.g., captive screws, cam locks, pin clips, etc.) may be applied for cleaning or decontamination.

[0169] A marker for three-dimensional visualization mapping (e.g., laser marker, QR / AR tag, etc.) is optionally placed on the outer surface of the outer panel to facilitate coordinate alignment with the data processing module (210).

[0170] The outer panel implements a smooth human body curve as shown in the example on the right side of Fig. 2, while managing the surface roughness (Ra) and elastic modulus as design values ​​to simulate actual protective clothing friction or contact conditions.

[0171] If necessary, a buffer layer or thermal humidity sensor can be inserted between the outer shell and the frame to evaluate the effects of micro-deformations and micro-airflows occurring during operation.

[0172] Looking at the wiring, piping, and power configuration, signals generated from the sensor module are aggregated into a signal aggregation unit via cable / tube conduits, and the interface with the outside of the mannequin can be established through interface ports located on the bottom or rear.

[0173] The interface port may include a wired (Ethernet, serial, power, etc.) or wireless (Wi-Fi, Bluetooth, dedicated RF, etc.) communication module.

[0174] Power can be supplied from a tethered external power source or an internal battery pack of the mannequin, and the battery pack can be encapsulated to meet explosion-proof and waterproof ratings.

[0175] Looking at the design for the joint and motion implementation, the joint provides degrees of freedom for rotation and bending, but may include an angle limiting stopper and a repetitive fixed position constraint to maintain the reproducibility of the protection performance evaluation.

[0176] To implement operation, a motor, reduction gear, torque sensor, etc., may be installed on the actuator mounting base, and a heat shield or a heat path separation structure may be applied so that heat generated by the actuator does not affect the sensor.

[0177] Looking at the placement principles and response to vulnerable areas by body part, the placement of the sensor module (110) prioritizes vulnerable areas connected to seams and joints, such as the head, neck, shoulders, chest, armpits, abdomen, groin, buttocks, elbows, knees, wrists, and ankles, and the steam sensor and particle sensor are placed in close proximity in the same area to compare and analyze the simultaneous behavior of steam or aerosol.

[0178] If necessary, a local sampling channel can be formed around the vulnerable area to amplify and collect minute leaks, which can then be guided to the sensor.

[0179] Regarding calibration, cleaning, and environmental resistance, each sensor module (110) can be calibrated on-site with a standard gas or standard particles (nebulizer-based) through a calibration port, and the outer panel and frame are made of materials with respect to chemical resistance to decontamination agents and cleaning agents.

[0180] The mannequin surface and joints can adopt curved surfaces and drain structures that minimize liquid and particle residue.

[0181] When looking at the visualization and coordinate alignment, the data processing module (210) aligns the location information of the sensor module (110) with the frame-based coordinate system, and then uses the markers of the outer panel to display the concentration and protection index of each part on the 3D model as a real-time heatmap.

[0182] Angle information of the joints is acquired synchronously, allowing for the comparison of distribution changes by operating state in a time series.

[0183] Meanwhile, the material and shape of the frame, the segment division method of the outer shell, the quantity, arrangement, and type of sensor modules, the specifications of the interface ports, the arrangement of the actuator mounting bases, and the method of the time synchronization means can be varied depending on the test purpose or environment, and such variations are also included within the scope of the present invention.

[0184] As described above, FIG. 2 illustrates the sensor placement and cabling at the frame level, the joint design, and the human body shape or joint structure in the finished outer shell state, thereby showing that the mannequin body (100) of the present invention is optimized for real-time measurement of each part under both stationary and operating conditions.

[0186] FIG. 3 is an example diagram of a mannequin for testing sensor placement inside the mannequin body and sensor mounting in a mannequin system for measuring real-time steam and aerosol protection performance according to one embodiment of the present invention.

[0187] Referring to FIG. 3, in a mannequin system for measuring real-time vapor and aerosol protection performance according to one embodiment of the present invention, the manufacturing process of the mannequin body (100) and the process of mounting the sensor are illustrated step-by-step, and are shown sequentially as follows: (A) a frame manufacturing step, (B) a vapor / aerosol sensor attachment step, and (C) a small sensor-mounted test mannequin completion example.

[0188] The composition and function of each stage are explained in detail below.

[0189] The mannequin body (100) is formed with a frame corresponding to standard human body dimensions, and the frame includes multiple segments corresponding to the head, neck, chest, abdomen, pelvis, upper limbs, lower limbs, etc., and joints that allow flexible movement between segments.

[0190] The frame may be composed of an aluminum alloy extruded material or a composite material reinforcing beam, and each segment has a sensor mount fastening hole and a boss structure formed for mechanical fastening of the sensor module (110).

[0191] Cable / tube conduits for data and power routing are integrated into the frame, and quick connectors with waterproof connectors are placed at the ends of each segment to ensure workability during disassembly, replacement, and cleaning.

[0192] A signal aggregator and an interface port for connection with external instrumentation and control devices are positioned on the lower or rear side of the frame, and the interface port optionally includes a wired (Ethernet / serial) or wireless (dedicated RF / wireless LAN) communication module.

[0193] The joint may include an angle limiting stopper and a reference position constraint structure to ensure repeatability, and an actuator mounting seat for motion testing is provided in advance.

[0194] The sensor module (110) is composed of at least a combination of a steam sensor and a particle sensor, and is placed in pairs in the same or adjacent areas to operate complementarily.

[0195] The sensor module (110) is connected to the inner boss of the frame or outer panel through a sensor mount.

[0196] Sensor placement is centered on seam and joint-linked vulnerable areas such as the head, chest, abdomen, arms, legs, armpits, groin, knees, and elbows, and an address system and time stamp can be assigned so that penetration data for each area can be acquired via independent channels.

[0197] Each sensor module (110) is equipped with an intake or exhaust port, and a fine mesh or anti-fouling filter is installed in the port to suppress the inflow of foreign matter and re-contamination.

[0198] If necessary, a sampling channel or small-diameter fitting can be added to amplify local leakage signals.

[0199] Sensor cables and sample tubes are organized into cable / tube conduits and integrated into signal aggregation units, while power distribution and communication are standardized via harnesses to ensure compatibility during replacement or expansion.

[0200] For calibration, calibration ports are positioned at each key section to allow the injection of standard gas (vapor) or standard particles (nebulizer-based), and calibration coefficients are applied independently to each section during data processing.

[0201] An outer shell panel for realizing the exterior shape is assembled to the frame, and a marker (laser marking / QR tag, etc.) for visualization coordinate alignment is optionally attached to the outer surface of the shell.

[0202] The outer shell (130) is formed as a curved surface with minimized hard-to-clean surface to ensure cleanliness and ease of detoxification.

[0203] The sensor module (110) is placed inside the outer shell in a miniaturized housing, and only a port or thin vent of the minimum necessary area is formed on the surface of the outer shell to minimize the impact of physical interaction (friction or contact) with the protective suit.

[0204] The completed test mannequin can be operated in both stationary and operating conditions, and is linked in real-time with an external data processing module (210) and an operation control module (220) through an interface port.

[0205] During motion testing, angle and velocity information of the joints allow for time-series analysis of penetration behavior by motion state using sensor data.

[0206] For the head and neck area, vapor and particle sensors are placed in close proximity around the occipital region, temporal region, and mandibular line to detect leakage at the hood and mask boundaries.

[0207] The chest and abdominal areas are distributed and positioned above the sternum, between the intercostal areas, and around the navel to measure changes in tightness according to breathing and trunk movement.

[0208] The upper and lower limbs and joint parts are concentrated in flexed areas such as the armpits, elbows, wrists, groin, knees, and ankles to detect leakage in seams and bands with high sensitivity.

[0209] The configuration of paired sensors in the same location enables the comparison of delay time differences and propagation path differences of vapor or aerosols, and if necessary, temperature and humidity correction sensors are added at the same location to apply correction factors during the data processing stage.

[0210] To ensure data quality, signal lines are routed separately from power lines, and shielded cables and grounding points may be applied to reduce electromagnetic interference (EMI).

[0211] When using wireless communication, frequency channel management and packet time stamps are assigned to prevent signal collisions, and PTP-based synchronization can be applied to synchronize to the same reference time even in a mixed wired / wireless environment.

[0212] Considering maintenance and cleaning processes, identification tags and quick connectors are applied to the cable ends, and captive fasteners may be used for the sheath to reduce wear from repeated disassembly and assembly.

[0213] Function check is performed by applying reference gas and particles through the calibration port after self-diagnosis of the sensor module (110) to perform zero and span calibration.

[0214] The static condition test involves setting the external exposure concentration and flow rate, and then acquiring the time change of penetration concentration by part in a static state.

[0215] The operation condition test performs walking and limb movements according to the motion control scenario and compares the change in relative protection performance compared to standing still.

[0216] In the result visualization, the data processing module (210) matches the sensor location coordinates to output a heat map and a concentration map in real time on a 3D model, and automatically calculates a list of vulnerable areas and indicators by condition.

[0217] The housing shape, port location, filter specifications, and communication standards of the sensor module (110) can be changed according to the test environment, and such changes correspond to equivalent substitutions.

[0218] Coordinate alignment can be performed using an external optical tracker instead of a marker on the outer shell, and the layout of the cable / tube conduit can be rearranged according to the protective suit model and test scenario.

[0219] The degrees of freedom of the joint, the stopper range, and the actuator specifications can be adjusted according to the purpose of the test, and all such design changes within a range that does not degrade data quality are included within the scope of this embodiment.

[0220] As described above, FIG. 3 shows that the mannequin body of the present invention stably performs real-time measurement by part, simultaneous evaluation of steam and aerosol, and comparison of stop and operation conditions through a series of implementation examples ranging from frame fabrication to sensor attachment and a finished body equipped with a small sensor.

[0222] FIG. 4 is a flowchart showing the overall flow of a method for measuring real-time vapor and aerosol protection performance according to another embodiment of the present invention.

[0223] Referring to FIG. 4, the flow of a method for measuring real-time vapor and aerosol protection performance according to another embodiment of the present invention is illustrated.

[0224] Referring to FIG. 4, a method for measuring real-time vapor and aerosol protection performance according to another embodiment of the present invention includes three steps.

[0225] In the first step (S100), a plurality of sensor modules (110) are used to detect in real time the concentration information of vapor or aerosol penetrating into the protective suit worn by the mannequin body (100).

[0226] In the second step (S200), the detection data is analyzed in real time using the data processing module (210), and the protective performance of the protective suit is calculated based on the result.

[0227] In the third step (S300), the motion control module (220) is driven to evaluate the protection performance in the operating state of the mannequin body (100).

[0228] I will explain this in more detail.

[0229] The present method is configured to quantitatively evaluate the protective performance of a protective suit under stop and motion conditions, and under single and mixed exposure conditions, by including real-time detection (S100) from multiple sensor modules (110) inside the mannequin body, real-time analysis of detection data and calculation of indicators (S200), and evaluation of the operating state of the mannequin (S300).

[0230] Step 1 (S100) is a step of detecting in real time the concentration information of vapor or aerosol penetrating into the protective suit worn by the mannequin body (100) using a plurality of sensor modules (110).

[0231] The sensor module (110) includes at least a sensor for detecting vapor and a sensor for detecting particles (aerosol), and is distributed and arranged at multiple locations such as the head, chest, abdomen, arms, legs, and joints of the mannequin.

[0232] Each sensor module (110) generates a packet containing time information and a part identifier along with the measurement value and transmits it to a data processing module (210) via a wired or wireless communication channel.

[0233] During the detection process, the sensor module (110) may refer to auxiliary sensors such as temperature, humidity, and pressure for environmental correction, and if necessary, the sensor output may be transmitted after primary preprocessing such as low-frequency drift removal and noise filtering (e.g., moving average, Kalman filter).

[0234] To ensure test reliability, it is possible to perform a zero or span calibration sequence immediately before the start of measurement, or to set a baseline of a reference area and convert it into a relative concentration.

[0235] The second step (S200) is a step of analyzing the detection data collected in the first step (S100) in real time using a data processing module (210) and calculating the protective performance of the protective suit based on the results.

[0236] The data processing module (210) time-synchronizes the received packet and matches it with the sensor location coordinates to form a time-location mapping data set.

[0237] Next, after performing quality control procedures such as removing outliers from measurements, correcting drift, and interpolating missing values, the penetration concentration by site Wow, external standard concentration Using this, protection indicators can be calculated as shown in the following Equations 1 and 2.

[0238] [Formula 1]

[0239]

[0241] [Equation 2]

[0242]

[0243] - Here, is a zero-division prevention constant.

[0245] Exposure conditions for vapor alone, aerosol alone, and a mixture of vapor and aerosol are stored and distinguished by condition tags, and the module calculates indicators for each condition independently or simultaneously, outputting them as comparison tables and time series curves.

[0246] The analysis results are visualized in real-time as a heatmap or concentration map on a 3D model of the mannequin, and areas exceeding a threshold are indicated as warnings or notifications.

[0247] If necessary, summary indicators (maximum value, average value, 95th percentile, cumulative penetration amount, etc.) are automatically calculated for each test unit (section / cycle) and recorded cumulatively in the result report template.

[0248] The third step (S300) is a step of driving the operation control module (220) to evaluate the protection performance in the operating state of the mannequin body (100).

[0249] The motion control module (220) controls one or more movements, such as walking, sitting, and limb flexion, to be performed with cycles, speeds, and ranges of motion, and the motion status flag is recorded in synchronization with the sensor data.

[0250] The data processing module (210) calculates the change in the indicator of the operating section relative to the stopping section to quantify the dynamic leakage effect (e.g., joint opening, rapid increase due to seam separation).

[0251] If necessary, the third step (S300), which is the operation step, is repeated according to the purpose of the test, and sensitivity analysis according to changes in the operation scenario (speed, attitude, period) is possible.

[0252] The optional steps and operational details are as follows.

[0253] To ensure reproducibility, each test is performed through the same initialization procedure (calibration, baseline setting, flow rate stabilization), and the number of repetitions and statistical processing criteria can be specified in advance.

[0254] For safety and error handling, events such as communication interruption, sensor saturation, and range exceedance are recorded in the event log, and the corresponding section can be automatically masked or remeasured.

[0255] To produce results, at the end of the test, the system can generate an automatic report including a summary table by condition and part, a list of vulnerable parts, a comparison graph, and a 3D distribution image.

[0256] Meanwhile, the above-described step division is merely an example to aid understanding, and even if steps are performed in parallel, the order is changed, or some steps are omitted or added, as long as real-time detection is performed by a plurality of sensor modules (110), analysis and calculation are performed by a data processing module (210), and an operation state evaluation is performed by an operation control module (220), it is included in the concept of the method of the present invention.

[0257] Furthermore, the specific formula of the protection indicator, the visualization method, the threshold determination logic, and the details of the calibration procedure may be modified by a person skilled in the art to suit the purpose and environment, and such equivalent variations are also included within the scope of the present invention.

[0258] For example, a method for measuring real-time vapor and aerosol protection performance according to another embodiment of the present invention relates to a procedure for quantitatively evaluating the performance of a protective suit under both stationary and operating conditions by using a system in which a plurality of sensor modules (110) are arranged by part on a mannequin body (100) that mimics the shape of a human body, measuring the behavior of vapor or aerosol penetrating into the protective suit in real time, and calculating and comparing protection performance indicators by part based on the collection and analysis results of the measurement data.

[0259] The present method includes the following steps.

[0260] Step 1 (mannequin preparation) is the step of putting a protective suit on the mannequin body (100).

[0261] At this time, the standard dimensions, outer shell shape, and joint angles of the mannequin are set to conform to the test protocol, and the method of wearing the protective suit (size, tension of fastening parts, zipper and band fastening status) is recorded to ensure reproducibility.

[0262] If necessary, the presence of interference in internal wiring and piping, sensor operating status (power and self-diagnosis), and whether a baseline (zero value) is secured are checked in advance.

[0263] Step 2 (setting exposure conditions) is a step of selecting one or more of vapor, aerosol, or a mixture thereof as the chemical substance to be tested, and setting the target concentration and flow rate of the external exposure conditions.

[0264] The type of exposure source (generator), chamber volume, airflow uniformity, background concentration, and environmental factors (temperature, humidity, pressure) are stabilized according to the procedure, and setpoints and tolerance ranges are recorded as metadata.

[0265] In the case of mixture conditions, parameters such as the ratio of aerosols, generation and extinction constants, and standard particle PSD (Particle Size Distribution) are specified for the vapor.

[0266] The third step (real-time signal collection) is a step of collecting signals in real time regarding the concentration of vapor or aerosol penetrating into the protective suit through a plurality of sensor modules (110) provided at multiple internal locations of the mannequin body (100).

[0267] Each sensor module (110) generates a data frame including a part identifier and a time stamp and transmits it to a data processing module (210) via wired or wireless communication.

[0268] If necessary, the sensor output is transmitted after undergoing primary preprocessing (offset correction, moving average or low-pass filter, saturation and missing value masking), and auxiliary sensor values ​​such as temperature, humidity, and pressure are synchronously acquired and used for post-processing correction.

[0269] The fourth step (recording of operating conditions) is a step of recording the protective performance in dynamic conditions by the data processing module (210) by driving the operation control module (220) of the mannequin body (100) to perform one or more movements such as walking, sitting, and arm or leg movements.

[0270] Operation cycle, speed, range of motion, and stop or operation interval flags are stored in time-synchronized with the measurement data, and operation logs such as joint angles and torque are recorded in parallel.

[0271] This step can be optionally repeated to analyze sensitivity to changes in operating conditions (e.g., increase or decrease in leakage due to changes in speed and attitude).

[0272] Step 5 (real-time aggregation, analysis, and indicator calculation) is a step of aggregating and analyzing the data collected in Step 3 in real time to normalize it into a data set including time information and part information, and calculating a protective performance indicator for each part from the data by the data processing module (210).

[0273] The data processing module (210) performs quality control procedures such as time synchronization, outlier removal, drift correction, and missing value interpolation, and external reference concentration and internal concentration Construct a time-local map by matching.

[0274] Indicator calculation is, for example, penetration rate , protection index (step, It may include expressions such as (zero denominator prevention constant), but is not limited thereto.

[0275] The results are visualized in real time as a heatmap or concentration map on the 3D model of the mannequin, a graph of the relative change of the stopping section compared to the moving section, and distribution statistics (average, maximum, 95th percentile, cumulative amount, etc.).

[0276] Step 6 (identification of vulnerabilities by part and comparison between conditions) is a step of identifying vulnerabilities by part of the protective suit and comparing the protective performance between vapor, aerosol, and mixture conditions based on the results of Step 5.

[0277] Areas exceeding the threshold are marked with a warning, and a list of vulnerable areas and improvement recommendations (seam reinforcement, sealing structure change, material replacement, etc.) can be automatically generated.

[0278] Not only can comparisons between conditions for the same protective suit be performed, but comparisons between different protective suit models can also be conducted using the same indicator system.

[0279] As an optional procedure and operational consideration, calibration manages site-specific zero or span calibrations before and after testing, and field calibration values ​​by injecting standard gas or standard particles.

[0280] Reproducibility management minimizes inter-experiment variation by fixing test parameters such as the attachment / detachment protocol, exposure stabilization time, number of repetitions, and data acquisition period (sampling rate).

[0281] For safety and error handling, events such as sensor saturation, communication delay and disconnection, and out-of-range are logged, and the corresponding sections are replaced with automatic masking or remeasurement routines.

[0282] When the test is finished, results such as a summary table by condition, indicators by part, 3D distribution images, and rates of change relative to operation can be automatically output as a report.

[0283] Meanwhile, the above-mentioned step division is merely an example for understanding, and even if the order of steps is changed, parallel execution is performed, or some steps are omitted or added, the method is included in the concept of the present invention as long as it includes real-time detection by a plurality of sensor modules (110), analysis and indicator calculation by a data processing module (210), and evaluation of the operation status by an operation control module (220).

[0284] In addition, indicator calculation formulas, visualization formats, threshold determination logic, data normalization and correction techniques, and detailed values ​​of exposure parameters can be appropriately modified by those skilled in the art depending on the test purpose and environment, and such equivalent variations also fall within the scope of the present invention.

[0285] The method embodiment described above quantifies the protective performance of a protective suit in real-time, by part, and by condition, and encompasses both stationary and active exposures, as well as single and combined exposures, thereby providing highly reliable evaluation results that can be immediately utilized for design improvement and standardization testing.

[0287] Figure 5 is an example graph of real-time overall and by-part performance analysis results.

[0288] Referring to FIG. 5, an example is illustrated in which the analysis results calculated from the mannequin system (1000) for measuring real-time steam and aerosol protection performance according to the present invention are visualized and displayed as overall indicators and indicators by part.

[0289] The graph on the left shows an example of comparison of total penetration rates (%) for test conditions A and B, and the panel on the right shows an example of multiple bar graphs of penetration rates by sampling location based on the front and back of the human body.

[0290] The penetration rate (%) indicated in the present invention is an external reference concentration Wow, a specific part inside the mannequin Internal concentration at Using, a predetermined time interval During this time, it can be calculated using the following formulas 3 and 4.

[0291] [Equation 3]

[0292] Instant Penetration Rate :

[0294] [Equation 4]

[0295] Section average penetration rate :

[0297] In addition, as needed, Protection Index (PF) = Alternatively, the cumulative penetration amount (integral value) may be indicated, and the present invention is not limited to the specific formula of the index.

[0298] All indicators are calculated through real-time quality control (outlier removal, drift correction, missing interpolation, etc.) in the data processing module (210).

[0299] The bar graph on the left plots the total penetration rate (%) calculated by integrating data from all parts for test conditions A and B, respectively.

[0300] Here, "A, B" may mean, for example, different protective suit models, different wearing conditions (sizing, fit), or different exposure conditions (vapor or aerosol composition, flow rate, concentration).

[0301] The total penetration rate can be calculated using one of the following formulas: Formula 5, Formula 6, or Formula 7.

[0302] [Formula 5]

[0303] Region-weighted average: (step, (This is the site weight; the default is uniform weighting)

[0305] [Equation 6]

[0306] Maximum-based indicators:

[0308] [Equation 7]

[0309] 95th percentile-based indicators :

[0311] The display method is selected according to the purpose of the test, and the graph can be updated in real time as the measurement proceeds.

[0312] The right panel shows an example in which the front and back silhouettes of the human body are shown, sampling locations (D01, D05, D10, D14, D20, D24, etc.) are indicated by dotted lines or arrows, and the penetration rate (%) of conditions A and B for each location is displayed in parallel as a small bar graph.

[0313] Each small window is at the corresponding location or Displays selection indicators.

[0314] By dividing and arranging them into front and back sections, the impact of spatial asymmetry (e.g., vulnerable areas such as the armpit, groin, and shoulder blade) is intuitively understood.

[0315] The data processing module (210) can assign a warning marker to each window when a threshold (e.g., 50% penetration rate) is exceeded, or display the risk level with color saturation / hatching.

[0316] The graph shown in Fig. 5 can be updated along the time axis not only during stationary conditions but also during motion conditions (walking, sitting, limb flexion).

[0317] Since the motion flag / joint angle provided by the motion control module (220) is recorded in synchronization with the data, the system (1000) can display the change in the relative penetration rate of the motion section compared to the stop section, the point of maximum penetration at each motion cycle stage (swing / stance, etc.), and the sensitivity according to the change in motion speed and range of motion by overlaying them on a graph for each part.

[0318] To ensure the reliability of the analysis, each bar contains the standard deviation, confidence interval (CI), and number of iterations. Auxiliary information such as error bars or comments may be included, and the difference between A / B conditions is paired comparison (e.g., It may be additionally indicated as ) or ratio (%).

[0319] If necessary, it can be extended to multiple condition (A / B / C…) comparisons, time-slice spaghetti plots, cumulative histograms, etc.

[0320] The visualization in Fig. 5 supports the derivation of the following conclusions.

[0321] The graph on the left allows for a quick comparison of overall protection levels between models or conditions.

[0322] If the penetration rate at a specific location on the right side of the seam is significantly higher than in other areas, structural vulnerabilities such as seams, zippers, bands, and joints may be suspected.

[0323] Improvement plans, such as reinforcement design for vulnerable areas, changes to sealing structures, and modifications to sizing / wearing protocols, are derived, and the effectiveness is quantitatively verified through A / B comparisons before and after the improvements.

[0324] The graph form in Fig. 5 is merely an example and can be replaced with equivalent means of information representation such as line graphs, box plots, violin plots, 3D contour maps, and interactive heat maps, and the formula, weights, thresholds, front / back splitting method, number of sampling locations, and names of the indicators can also be changed according to the purpose of the test.

[0325] These variations are also included within the scope of the technical concept of the present invention.

[0326] As described above, FIG. 5 shows that the data processing module of the present invention can simultaneously visualize the results calculated through time-part matching as overall indicators and part-specific indicators, thereby enabling real-time, quantitative, and spatial evaluation of the protective performance of the protective suit and immediate improvement feedback.

[0328] As such, according to the present invention, in order to quantitatively evaluate the chemical protection performance of a protective suit in real time, the existing testing method was a post-processing method in which samples were collected and analyzed after the test was completed. However, the present invention collects and analyzes data in real time from a vapor measurement sensor and an aerosol measurement sensor embedded inside a mannequin, thereby allowing the degree of chemical penetration into the protective suit to be immediately identified even during the test. Accordingly, changes in the barrier performance of the protective suit can be continuously observed on the time axis, and the initiation point of penetration and the location of leakage can be tracked in real time.

[0329] Furthermore, according to the present invention, in order to enable the integrated evaluation of protective performance in a complex threat environment involving vapors and aerosols, vapor-phase chemicals and aerosol-phase particles are controlled simultaneously or independently within a single system, and the penetration amount of each substance can be measured under the same test conditions. This eliminates the need to operate two types of test equipment separately as in the past, and allows for the precise reproduction of complex chemical exposure conditions in actual operational environments or industrial disaster sites, thereby providing the effect of enabling the evaluation of the comprehensive blocking capability and mutual influence of the protective suit.

[0330] In addition, according to the present invention, by equipping the arms, legs, and torso of a mannequin with driving modules to enable various movements such as walking, sitting, and arm swinging, it is possible to perform dynamic protective performance evaluation reflecting human movement conditions. This allows physical factors such as changes in the tightness of the protective suit, tensile deformation of the material, and widening of seam gaps that occur according to actual human movement to be reflected in the test, thereby enabling the quantitative analysis of the rate of degradation of blocking performance under dynamic conditions compared to static conditions of the protective suit. This has the effect of serving as a key basis for future structural design and material improvement of the protective suit.

[0331] In addition, according to the present invention, in order to provide design feedback through analysis of penetration vulnerability by area, individual data is collected from a plurality of sensors distributed in each part of the mannequin, allowing for the quantitative comparison of protective performance by detailed areas such as the head, chest, abdomen, limbs, seams, and zippers. Through this, vulnerable areas where chemical penetration occurs relatively frequently can be identified, and immediate feedback can be provided regarding the structural design, material selection, and sealing structure improvement of the protective suit.

[0332] In addition, according to the present invention, in order to enable real-time visualization and automatic analysis of measurement data, data collected through a sensor network is integrated and analyzed in real time by a central control module, and the amount of penetration for each part is visualized in a three-dimensional graphic form such as color, concentration, and time change. Through this, the tester can intuitively recognize the distribution of the overall protective performance, and since the performance index (report index) is automatically calculated immediately after the test ends, the test efficiency can be significantly improved.

[0333] In addition, according to the present invention, in order to improve the reproducibility and reliability of the test, it is configured to perform multiple repeated tests under the same test conditions using an automatic control method. By minimizing variable factors caused by experimenter intervention, deviations between test results are reduced, and the concentration, flow rate, exposure time, etc. of the chemical substance can be precisely controlled, thereby having the effect of simultaneously ensuring test reproducibility and data reliability.

[0334] Furthermore, according to the present invention, in order to have the potential for expansion into an international standardized testing system, it is applicable not only to testing of CBRN protection systems in the defense sector but also to various application fields such as industrial safety and health, environmental disaster response, and biological aerosol blocking evaluation, and has the effect of being utilized in establishing criteria for international testing standards (ISO, ASTM, MIL-STD, etc.).
