Description

Technology Field

[0001] The present invention relates to a CBRN contamination mapping system and method using a walking energy-based self-generating replaceable sole, comprising a detachable and replaceable sole for military boots or shoes worn by a soldier, converting walking energy into electrical energy to drive a contamination sensing module in a self-generating manner, and, in addition, generating a contamination distribution map of the ground or road surface by linking location and time information with CBRN contamination-related data such as chemical substances, biological agents, and radioactive materials continuously acquired during movement, and providing the generated contamination map and contamination situation assessment results to an individual soldier terminal, a squad-unit terminal, or a command and control system to support responses such as avoiding contaminated areas, wearing protective equipment, and performing decontamination. Background Technology

[0003] Modern battlefields and disaster sites are characterized by CBRN threats—such as chemical leaks, the spread of biological contamination, and the dispersion of radioactive materials—occurring suddenly in unspecified areas or rapidly changing in their patterns of diffusion over time. Consequently, there is a problem in that the boundaries and risk levels of contaminated zones frequently shift during the movement of troops or on-site response personnel, and the potential for individual exposure accumulates differently depending on the movement route.

[0004] Conventional CBRN response has often relied on passive protection using equipment such as gas masks, protective suits, and personal handheld detectors, or on one-off measurements at the individual level. Additionally, methods involving measurements at limited points—such as fixed stations, sample collection and analysis, and vehicle-mounted equipment—have been widely used to assess contamination levels.

[0005] However, these conventional methods have problems such as difficulty in continuously measuring contamination levels with sufficient spatial resolution along the entire movement path when troops or response personnel are moving on foot over a wide area to perform missions, inability to accurately estimate contamination boundaries due to gaps between measurement points, and delays in providing information necessary for real-time decision-making because the collection, transmission, and integration of measurement results take time.

[0006] In addition, personal portable detectors or separate sensor equipment must be carried or operated by the user, which increases the operational burden. Furthermore, power supply, charging, and battery replacement of the sensor equipment are essential during missions, making continuous detection difficult during long-term operations or in environments with limited power infrastructure. As a result, contamination data may be interrupted, which can reduce the continuity of situational awareness.

[0007] Furthermore, an integrated operational system that collectively combines contamination-related data acquired by multiple soldiers from different locations to estimate the contamination distribution, updates a contamination map reflecting trends over time in real time, and simultaneously shares the results with individual soldiers, squads, and the command and control system to induce responses such as route changes, avoidance of danger zones, wearing protective equipment, and decisions on whether to perform decontamination has not been sufficiently implemented in conventional technology.

[0008] In particular, although individual soldier systems are evolving to integrate various sensors, communication equipment, and situational awareness devices to enhance soldiers' combat capabilities and survivability, military boots or footwear remain in the category of protective clothing; consequently, there was a limitation in that it was difficult to utilize them as an active platform for CBRN situational awareness by leveraging the advantage of constant operation during soldier movement.

[0009] Therefore, there is a need for technology that integrates contamination sensing and communication functions in the form of detachable and replaceable soles on combat boots or footwear, which are essential equipment for soldiers; enables continuous measurement for extended periods without a separate power infrastructure through self-generation using walking energy; and supports collective response by analyzing the movement history and contamination data of multiple soldiers using artificial intelligence to estimate contamination distribution and trends, and sharing the results with the command and control system.

[0039] 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.

[0040] 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

[0042] As such, according to the present invention, since a contamination sensing function is integrated in the form of a detachable and replaceable sole on military boots or shoes, which are essential equipment for soldiers, the soldier's movement itself acts as a process for acquiring contamination data, thereby enabling continuous awareness of chemical, biological, radiological, and nuclear (CBRN) situations during operations without the need to carry separate measuring equipment or stop at a specific point to take measurements.

[0043] In addition, according to the present invention, by including a self-generating means for converting walking energy into electrical energy in a replaceable sole, pollution sensing and communication functions can be stably maintained for a long time even in environments where external power infrastructure is limited, thereby reducing the problem of monitoring being interrupted or data being cut off due to conventional battery depletion, charging standby, and power management burdens.

[0044] In addition, according to the present invention, contamination-related data collected from a replaceable sole is wirelessly transmitted to a personal soldier terminal, and contamination level information linked with location and time information is generated at the terminal and visualized on a map or provided as a warning notification. Consequently, the soldier can intuitively recognize the contamination risk zone and perform immediate responses such as changing movement routes, restricting entry, and wearing protective equipment, thereby improving the speed and accuracy of on-site response.

[0045] In addition, according to the present invention, the movement history and contamination-related data of multiple soldiers are integrated into an artificial intelligence processing unit, so that the contamination distribution along the troop movement path is estimated and the trend of changes in the contamination situation over time is determined. Consequently, fragmented measurement results at the individual level are converted into an integrated contamination map at the troop level, thereby enabling collective situation awareness and cooperative response.

[0046] In addition, according to the present invention, since the judgment results of the artificial intelligence processing unit are shared with individual soldiers, squad units, and the command and control system through the information dissemination unit and can be reflected in operational control, command decisions such as setting and updating contaminated zones, suggesting safe routes, determining decontamination priorities, and adjusting mission plans are consistently executed based on objective data, thereby improving operational efficiency and safety.

[0047] Furthermore, according to the present invention, maintenance, cleaning, replacement, and resupply of the contamination sensing module are facilitated by the replaceable sole structure. This reduces the field operational burden regarding contamination, deterioration, and failure of equipment in contaminated environments, and enables large-scale operation of multiple troops and system scalability. As a result, it has the effect of substantially improving the survivability and operational sustainability of soldiers under chemical, biological, radiological, and nuclear (CBRN) threats.

[0152] FIG. 4 is a diagram exemplifying the operation scenario and information sharing flow of a CBRN contamination mapping system using a walking energy-based self-generating replaceable sole according to an embodiment of the present invention.

[0153] Referring to FIG. 4, a chemical, biological, radiological, and nuclear (CBRN) contamination mapping system (1000) according to one embodiment of the present invention is configured to continuously acquire CBRN contamination-related signals during a soldier's movement using a sensor unit (100), a control communication unit (200), and a walking energy harvesting power unit (300) included in a replaceable sole module (400), and to transmit the acquired contamination-related data to an external terminal (500) through a wireless communication device (406) to support situation awareness and response at the individual soldier and troop unit level.

[0154] Specifically, the first stage of FIG. 4 represents a state in which a soldier moves while performing a chemical, biological, radiological, and nuclear (CBRN) reconnaissance mission, and in this process, a replaceable sole module (400) mounted on the soldier's military boot or shoe introduces external air through a contaminated external air inflow (411), transports the inflow air by an air pump system (410), and controls the air flow path by an air flow switching system (408) so that the sensor unit (100) can stably detect a contamination-related signal corresponding to the contaminated gas (409).

[0156] In parallel with this, the walking energy harvesting power unit (300) generates power by utilizing the piezoelectric effect (407) generated by the soldier's walking, and stores the generated power in a rechargeable battery (404) or supplies it as operating power to the sensor unit (100) and the control communication unit (200), thereby enabling continuous sensing even in an operational environment where external power infrastructure is limited.

[0157] Additionally, the control communication unit (200) may be configured to include a microcomputer (405) to generate or preprocess contamination-related data from a detection signal of the sensor unit (100) and to transmit said contamination-related data to an external terminal (500) via a wireless communication device (406).

[0159] For example, the external terminal (500) can provide one or more of a warning message, sound, vibration, and screen display when the contamination level is above a preset threshold so that the soldier can immediately recognize the danger, and if necessary, instruct the soldier to wear protective equipment or guide him to restrict entry into the contaminated area.

[0160] The third stage of FIG. 4 represents a situation in which a soldier continues to perform a mission while wearing protective gear, and during this process, the replaceable sole module (400) can continuously generate power according to walking and repeatedly or continuously detect pollution-related signals to continuously provide pollution-related data reflecting the trend of changes in the pollution situation to an external terminal (500).

[0161] Accordingly, soldiers can continue to perform their missions while monitoring changes in contamination levels along their movement routes, shifts in the boundaries of contaminated zones, and the locations of safe zones in real-time or near-real-time.

[0162] Step 4 of FIG. 4 represents a situation in which real-time contamination mapping results are checked in a command and control room or a higher-level system, and the external terminal (500) can be configured to generate contamination level information by linking location information and time information to the contamination-related data, visualize and display the generated contamination level information on a map, and, if necessary, integrate data collected from multiple soldier terminals to update the contamination distribution at the troop level.

[0163] Additionally, the external terminal (500) can transmit the generated contamination information or contamination map to a higher-level system so that the command and control system can utilize it to perform operational control decisions such as setting contamination zones, suggesting safe routes, coordinating mission plans, and determining decontamination priorities.

[0164] Accordingly, as illustrated in FIG. 4, one embodiment of the present invention utilizes a replaceable sole module (400) mounted on a military boot or shoe as an active sensing platform for a personal soldier system to continuously recognize chemical, biological, radiological, and nuclear (CBRN) contamination situations during the soldier's movement, and by performing visualization and sharing of contamination information through linkage with an external terminal (500), it can provide the effect of enabling not only immediate response by the individual soldier but also collective situation awareness and command and control support at the troop level.

[0165] In addition, in one embodiment of the present invention, an external terminal (500) or a higher system may be configured to aggregate contamination-related data received from multiple replaceable sole modules (400) in units of location intervals or grids, and to generate or update contamination level information by weighted combination based on one or more of a measurement time, a reliability index, and the number of repeated measurements. In cases where different measurement results exist in the same area, the contamination level value may be determined according to one or more rules, such as prioritizing the latest value, majority rule, or time-weighted average.

[0166] Additionally, the control communication unit (200) or external terminal (500) may be configured to temporarily store contamination-related data in internal memory when communication quality deteriorates or is interrupted, and to retransmit or synchronize the stored data in chronological order when communication is restored, and may be configured to include a sequence number or message identifier to prevent duplicate transmission.

[0167] Additionally, the external terminal (500) or the upper system may be configured to update contamination level information at the troop level by removing spatial and temporal overlap of contamination-related data received from multiple soldiers and performing data combination by assigning weights based on one or more of reliability indicators, measurement time, position error, and sensor status values, and may be configured to automatically calculate the boundary of a danger zone, a safe path, or an entry restriction zone based on the updated contamination level information and provide it to the soldier or the command and control system.

[0185] In addition, according to another embodiment of the present invention, the contamination-related data transmitted in the fourth step (S400) can be linked with location information and time information at an external terminal (500) to generate contamination level information, and the generated contamination level information can be visualized on a map to support responses such as changing the soldier's movement path, wearing protective equipment, and restricting entry. When data from multiple soldiers is aggregated, it can be utilized by a higher-level system or an artificial intelligence processing unit to estimate the contamination distribution and determine the trend of change, thereby enabling collective situation awareness and command and control support at the troop level.

[0186] Accordingly, as illustrated in FIG. 5, another embodiment of the present invention can provide the effect of supporting continuous situational awareness and rapid response to chemical, biological, radiological, and nuclear threats even in an environment where power infrastructure is limited by systematizing the procedure of driving the sensor unit (100) and the control communication unit (200) based on self-generation using the walking energy harvesting power unit (300) in the replaceable sole module (400), performing air sampling-based detection including contaminated external air inflow (411), air pump system (410), air flow switching system (408), activated carbon (401), chamber and gas sensor (403), and transmitting the generated contamination-related data to an external terminal (500) via a wireless communication device (406).

[0187] Additionally, if the amount of power generated by the walking energy harvesting power unit (300) or the remaining amount of the rechargeable battery (404) in the first stage (S100) is less than a preset threshold, the control communication unit (200) may be configured to perform a low-power mode that extends the sampling period of the sensor unit (100) and the transmission period of the fourth stage (S400) or limits the operating time of the air pump system (410), and may be configured to perform an event-based operation that is woken up and performs measurement and transmission only when the pollution-related signal exceeds the threshold.

[0189] In addition, if communication quality deterioration or disconnection occurs in the fourth step (S400), the control communication unit (200) or the external terminal (500) may be configured to temporarily store contamination-related data in internal memory and, when communication is restored, retransmit or synchronize the stored data in chronological order, and may be configured to include a sequence number or message identifier to prevent duplicate transmission.

[0190] Meanwhile, the second step (S200) may include contaminated air inflow, pump transfer, flow conversion, adsorption or purification, and chamber sensing depending on the embodiment.

[0199] The control communication unit (200) is configured to generate contamination-related data based on the detection result of the sensor unit (100) and to transmit the generated contamination-related data via wireless communication, and can be embedded in the replaceable sole module (400) or arranged to be linked with the replaceable sole module (400).

[0200] The control communication unit (200) may be configured to improve the reliability of contamination-related data by collecting a signal input from the sensor unit (100) and performing one or more of digitization, filtering, noise removal, baseline correction, temperature and humidity correction, and sensor drift correction.

[0203] The walking energy harvesting power supply unit (300) may be configured to generate power using one or more of, for example, a piezoelectric method, an electromagnetic induction method, or a triboelectric method, and the generated power may be supplied directly to the sensor unit (100) and the control communication unit (200), or may be configured to be supplied as stabilized power after being stored in the energy storage unit.

[0204] Additionally, the walking energy harvesting power supply (300) may be configured to enable stable continuous operation even in environments where power infrastructure is limited by including a power management circuit that performs one or more of rectification, boosting or stepping down, overcurrent protection, overvoltage protection, and temperature protection.

[0205] The external terminal (500) can be implemented as a terminal that receives pollution-related data from the control communication unit (200) via wireless communication and provides pollution level information or warning information to the user.

[0206] The external terminal (500) can be implemented as a smartphone, tactical terminal, tablet, wearable terminal, or personal soldier terminal, and can be configured to generate pollution level information by linking location information and time information to received pollution-related data, including a location information generation function.

[0207] Additionally, the external terminal (500) can display the generated contamination information on a map basis, or provide one or more of a warning message, vibration, sound, or screen highlighting when the contamination level exceeds a preset threshold, thereby enabling the user to quickly recognize the danger zone and take countermeasures such as changing the movement path, restricting entry, or wearing protective equipment.

[0208] The artificial intelligence processing unit (600) is a processing unit for determining chemical, biological, radiological, and nuclear (CBRN) situations or estimating contamination distribution by aggregating contamination-related data collected from multiple users or multiple replaceable sole modules (400), and can be implemented by being included in a higher-level system or server separate from the external terminal (500).

[0209] The artificial intelligence processing unit (600) may be configured to determine the trend of change in the pollution situation by accumulating the movement history and pollution-related data of multiple users over time, and may be configured to improve the accuracy of situation awareness based on collective data by performing weighted combination, outlier removal, or duplicate removal based on one or more of the measurement time, reliability index, position error, and sensor status value for data collected in the same area or adjacent area.

[0210] Additionally, the artificial intelligence processing unit (600) may be configured to include judgment logic for estimating or updating the pollution distribution based on a grid, heatmap, or boundary line, and for calculating the danger zone boundary, safety path, or entry restriction zone if necessary.

[0211] The information dissemination unit (700) is configured to transmit the judgment result or contamination level information of the artificial intelligence processing unit (600) to an external terminal (500) or a command and control system (800) to induce a response, and can be implemented as a separate module included in a higher system or linked with the artificial intelligence processing unit (600).

[0212] The information dissemination unit (700) can be configured to enable collective response by disseminating one or more of danger alerts, danger zone boundaries, safe routes, and decontamination priority information to individual soldier or squad unit terminals, and can be configured to support operational control by transmitting judgment results to the command and control system (800).

[0213] The command and control system (800) can be implemented as a higher-level system that performs operational control decision-making based on contamination level information or chemical, biological, radiological, and nuclear (CBRN) situation judgment results provided by the information dissemination unit (700).

[0214] For example, the command and control system (800) may be configured to perform one or more of the following: setting and updating contaminated zones, presenting safe routes, setting entry restriction zones, performing decontamination and determining decontamination priorities, and coordinating mission plans, and may be configured to integrate data collected from multiple users to update the contamination distribution of troop units and to re-propagate the update results to subordinate units or field terminals.

[0215] In addition, in one embodiment of the present invention, the control communication unit (200) or external terminal (500) may be configured to temporarily store contamination-related data in internal memory when communication quality deteriorates or disconnects, and to retransmit or synchronize the stored data in chronological order when communication is restored, and may be configured to include a sequence number or message identifier to prevent duplicate transmission.

[0216] Additionally, communication between the control communication unit (200) and the external terminal (500) or communication between the external terminal (500) and the upper system may be configured to include one or more of encryption, authentication, and key exchange procedures to prevent eavesdropping and falsification of data, and the receiving side may be configured to use only reliable data as input for generating contamination information or situation judgment based on the integrity verification result.

[0217] In other words, the command and control system according to the present embodiment can be implemented as an example of an external system linked through an external terminal, and the essential configuration of the present invention can be achieved by linkage between a replaceable sole module and an external terminal.

[0218] Accordingly, as illustrated in FIG. 6, according to another embodiment of the present invention, a contamination-related signal is continuously acquired during walking movement through a replaceable sole module (400), and contamination-related data is generated by a control communication unit (200) and provided to an external terminal (500), thereby supporting immediate response at the user level. At the same time, data collected from multiple users is integrated into an artificial intelligence processing unit (600) to estimate the contamination distribution and change trends at the troop level, and is shared with a command and control system (800) through an information dissemination unit (700), thereby providing the effect of enabling collective situation awareness and command and control support.

[0219] Meanwhile, FIG. 6 illustrates an interlocking and extended embodiment that is not limited to the essential components of the present invention, and the artificial intelligence processing unit, information dissemination unit, and command and control system may be selectively applied as an example of an implementation environment or external system of the present invention.

[0221] As such, according to the present invention, since a contamination sensing function is integrated in the form of a detachable and replaceable sole on military boots or shoes, which are essential equipment for soldiers, the soldier's movement itself acts as a process for acquiring contamination data, thereby enabling continuous awareness of chemical, biological, radiological, and nuclear (CBRN) situations during operations without the need to carry separate measuring equipment or stop at a specific point to take measurements.

[0222] In addition, according to the present invention, by including a self-generating means for converting walking energy into electrical energy in a replaceable sole, pollution sensing and communication functions can be stably maintained for a long time even in environments where external power infrastructure is limited, thereby reducing the problem of monitoring being interrupted or data being cut off due to conventional battery depletion, charging standby, and power management burdens.

[0223] In addition, according to the present invention, contamination-related data collected from a replaceable sole is wirelessly transmitted to a personal soldier terminal, and contamination level information linked with location and time information is generated at the terminal and visualized on a map or provided as a warning notification. Consequently, the soldier can intuitively recognize the contamination risk zone and perform immediate responses such as changing movement routes, restricting entry, and wearing protective equipment, thereby improving the speed and accuracy of on-site response.

[0224] In addition, according to the present invention, the movement history and contamination-related data of multiple soldiers are integrated into an artificial intelligence processing unit, so that the contamination distribution along the troop movement path is estimated and the trend of changes in the contamination situation over time is determined. Consequently, fragmented measurement results at the individual level are converted into an integrated contamination map at the troop level, thereby enabling collective situation awareness and cooperative response.

[0225] In addition, according to the present invention, since the judgment results of the artificial intelligence processing unit are shared with individual soldiers, squad units, and the command and control system through the information dissemination unit and can be reflected in operational control, command decisions such as setting and updating contaminated zones, suggesting safe routes, determining decontamination priorities, and adjusting mission plans are consistently executed based on objective data, thereby improving operational efficiency and safety.

[0226] Furthermore, according to the present invention, maintenance, cleaning, replacement, and resupply of the contamination sensing module are facilitated by the replaceable sole structure. This reduces the field operational burden regarding contamination, deterioration, and failure of equipment in contaminated environments, and enables large-scale operation of multiple troops and system scalability. As a result, it has the effect of substantially improving the survivability and operational sustainability of soldiers under chemical, biological, radiological, and nuclear (CBRN) threats.
