Description

Technical Field

[0001] This invention relates to a stab-proof vest with a passive distress monitoring system. Background Technology

[0002] Traditional standard stab-proof vests only provide physical protection against punctures, lacking automatic hazard detection and distress call capabilities. When officers are injured, unconscious, or disabled by a knife attack, they cannot manually call for help, hindering timely rescue efforts by the command center and surrounding police forces, potentially escalating personal injury. While a few wearable devices with alarm functions are available, existing products have significant shortcomings in hazard identification capabilities. They rely solely on camera image capture and AI assistance for basic assessment, generating numerous false alarms during routine duty, interfering with normal operations and resulting in insufficient overall reliability. Furthermore, most products lack positioning and battery warning modules, failing to transmit precise distress coordinates or provide early warnings of low battery levels, leading to poor overall equipment maintenance and operational support capabilities. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a stab-proof vest with a passive distress monitoring system. This vest has a reasonable structural layout, is reliable in use, and achieves passive and automatic identification of hazards, thereby improving its effectiveness.

[0004] To achieve the above objectives, the present invention provides a stab-proof suit with a passive distress monitoring system, comprising a suit body, wherein the suit body is provided with a trigger module, a judgment module and a communication module; The trigger module includes several sub-trigger units, each sub-trigger unit including several densely arranged conducting coils. The conducting coils are used to generate a standby signal and a cut-off signal when the signal is cut off. The trigger module is used to send the cut-off signal and the standby signal to the judgment module. The judgment module is used to receive the cut-off signal and the standby signal. The judgment module generates a trauma signal based on the cut-off signal and sends the trauma signal to the communication module. The advantages of this setup are as follows: The trigger module contains multiple sub-trigger units with densely packed conductive coils. These coils normally output a standby signal, but upon puncture and breakage by a knife, they generate a cutting signal. The judgment module then generates a wound signal based on this cutting signal, which is subsequently transmitted to the control center via the communication module. The densely packed conductive coils form a normally closed loop structure, passively identifying puncture damage without requiring manual alarm triggering by officers. Even if officers are attacked, become unconscious, or suffer limb disability, the device can still autonomously collect the danger signal, overcoming the complete ineffectiveness of traditional button-type alarms in serious injury scenarios. The coils are flexibly integrated into the stab-proof vest's lining, without any hard metal protrusions, preventing stress concentration that could compromise the vest's original puncture resistance. The lightweight design does not increase the wearer's weight and does not restrict tactical movements such as running and blocking. The entire sensing structure operates with low power consumption around the clock, suitable for the 24 / 7 field duty needs of police officers, traffic police, and armed police. Puncture hazards can be quickly identified solely by changes in coil on / off state; the signal acquisition logic is simple, the MCU's computational load is low, and the overall standby battery life is longer. The communication module transmits trauma signals to the backend, allowing the command center to receive distress alerts immediately and dispatch rescue forces promptly, thus overcoming the shortcomings of traditional stab-proof vests that only provide physical protection and lack automatic distress call functionality. Meanwhile, the coil sensing structure boasts high stability, resistance to sweat and rain, and is less prone to signal failure in high and low temperature outdoor environments, significantly enhancing the safety of frontline duty equipment.

[0005] As a further feature of the present invention, the sub-trigger units are respectively located on the forearm, upper arm, left front chest, right front chest, upper abdomen, lower abdomen, left lower back, right lower back, and back.

[0006] The advantages of this setup are as follows: This configuration targets the areas most prone to violent attacks on police and knife punctures. Independent deployment of sub-triggers in each zone allows for precise location of injuries. When the control center receives a trauma signal, it simultaneously acquires the specific injured area, enabling rescue teams to carry appropriate first-aid supplies and shortening on-site response and patient treatment time. Compared to existing solutions where a unified sensor only determines the overall situation and cannot distinguish injury locations, the accuracy of rescue efforts is significantly improved. Each sub-trigger unit independently collects contact signals. Damage to the sensor layer in one area will not interfere with normal monitoring in other areas, resulting in higher equipment fault tolerance. Even minor compression or impact in some areas will only cause the corresponding area to output a momentary signal, while other modules maintain their normal baseline state, preventing false triggering of the entire unit. Modular deployment by region facilitates production assembly and subsequent maintenance. If a sub-trigger unit experiences conductive layer wear or isolation particle failure, only the corresponding sensor component needs to be replaced, eliminating the need to replace the entire trigger module and reducing equipment maintenance costs. The partitioned layout conforms to the curves of the human body, and the flexible trigger layer bends synchronously with the movement of the torso and limbs, without local stress accumulation. It is not easy for the conductive layer to crack or peel off after long-term wear. It is suitable for various field duty postures such as standing, patrolling, and squatting of traffic police, police officers, and armed police. It can stably collect contact signals around the clock to ensure continuous and effective identification of danger.

[0007] As a further feature of the present invention, the sub-trigger unit further includes two trigger layers disposed on adjacent flexible anti-stab layers, with a plurality of insulating isolation particles arranged between the two trigger layers. These insulating isolation particles are elastic and dotted. Each trigger layer includes a flexible substrate, a carbon-silver composite conductive layer coated on the substrate surface, and a surface wear-resistant insulating protective film. The edge of each trigger layer has a conductive contact strip for maintaining contact with the other trigger layer to generate a reference signal. Contact between the two trigger layers also generates location information, a small-area short-time contact signal, a large-area short-time contact signal, a small-area continuous contact signal, and... The triggering module is also used to send small-area short-time contact signals, large-area short-time contact signals, small-area continuous contact signals, and large-area continuous contact signals to the judgment module; the judgment module is used to receive location information, small-area short-time contact signals, large-area short-time contact signals, small-area continuous contact signals, and large-area continuous contact signals; the judgment module generates corresponding trauma information based on location information, small-area short-time contact signals, large-area short-time contact signals, small-area continuous contact signals, and large-area continuous contact signals, and sends the trauma signal to the communication module; The beneficial effects of this design are as follows: This design adds a double-layer trigger layer sensing structure to the conductive coil. The two trigger layers are positioned between two flexible anti-stab layers, complemented by dotted elastic insulating particles. The trigger layers are formed by a flexible substrate, a carbon-silver composite conductive layer, and a wear-resistant insulating protective film. The edge conductive contact band forms a normal reference signal, enabling the output of multiple contact signals and location information. The judgment module combines the contact signals to generate a comprehensive injury signal, achieving complementary dual sensing of coil open circuit and deformation contact. Under normal conditions, the insulating particles support the separation of the two trigger layers, with only the edges conducting, avoiding excessive power consumption caused by long-term large-area adhesion. The flexible and deformable carbon-silver composite conductive layer, along with the wear-resistant insulating film, isolates sweat and dust, ensuring stable conductivity over long-term use. By distinguishing between short-term, continuous, large-area, and small-area contact signals, it can accurately differentiate between external forces such as punches, heavy object impacts, and knife scratches. Simple impacts only generate instantaneous signals and will not trigger high-risk stab wound alarms, significantly reducing false alarms during operations. The dual-layer trigger layer can simultaneously output information about the injured area, allowing the backend to accurately locate the injured area and facilitate the delivery of appropriate first-aid supplies during rescue operations. The two sensor systems are redundant with each other. The coil identifies the depth of puncture, while the dual-layer contact layer distinguishes the type of external force. The failure of a single sensor does not affect the overall monitoring, completely solving the dual pain points of a single coil's inability to filter impact interference and a single-layer contact sensor's difficulty in identifying severe punctures. It balances recognition accuracy, device reliability, and wearability.

[0008] As a further provision of the present invention, the trauma signals include strike alarm, impact alarm, stab alarm, stab wound alarm, and serious injury alarm. The strike alarm is generated by combining the location information of at least two individual sub-triggered units with a large-area short-term contact signal. The impact alarm is generated by combining the large-area continuous contact signal and location information of multiple location sub-triggered units. The stab alarm is generated by combining the location information of a single sub-triggered unit with a small-area short-term contact signal. The stab wound alarm is generated by combining the location information of a single sub-triggered unit, a small-area continuous contact signal, and a cutting signal. The serious injury alarm is generated by combining the location information of multiple sub-triggered units, a small-area continuous contact signal, and a cutting signal.

[0009] The beneficial effects of this setup are as follows: This configuration allows for tiered alert notifications based on different violent scenarios, providing a refined advantage in handling incidents at different risk levels. The strike alarm relies on multiple, large-area, short-duration contact signals in a single area to determine the severity of minor conflicts such as shoving or punching. The system only records these incidents and does not initiate emergency rescue dispatch, thus avoiding the waste of rescue resources on minor physical altercations. The impact alarm relies on continuous, large-area contact signals in multiple areas to identify moderate impacts such as those from sticks or heavy objects, and the system sends out warnings to nearby officers to provide assistance. The stabbing alarm uses short-duration, small-area contact signals in a single area to determine shallow cuts from knives, providing early warning of potential danger. The stab wound alarm combines continuous contact signals at a single point with coil cut-off signals to determine effective puncture wounds, immediately initiating local rescue dispatch. The serious injury alarm covers multiple areas with puncture signals, determining multiple serious injuries and simultaneously coordinating with emergency medical services, patrols, and command departments for collaborative response. The tiered alarm mechanism allows the command center to intuitively differentiate the severity of emergencies, enabling tiered allocation of rescue resources and avoiding the waste of dispatch resources caused by issuing uniform highest-level alarms regardless of the scenario. Simultaneously, different alarm types carry corresponding body part information, allowing commanders to simultaneously grasp the location and severity of injuries and formulate precise rescue plans. The entire tiered judgment logic relies on low-power MCU computing, without significantly increasing overall power consumption. While accurately distinguishing various violent behaviors and reducing false alarms, it achieves standardized and intelligent emergency response, greatly improving the efficiency of police rescue dispatch and addressing the industry pain point that traditional alarm systems can only output a single distress signal and cannot differentiate the severity of injuries.

[0010] As a further feature of the present invention, a positioning module is also included, which is used to generate coordinate information and send the coordinate information to the communication module. The communication module is also used to receive coordinate information and send the coordinate information to the control center.

[0011] The advantages of this setup are as follows: The positioning module uses the BeiDou positioning system, which has signal compensation capabilities in urban buildings, tunnels, and shaded environments, resulting in minimal positioning error. It instantly locks in real-time latitude and longitude coordinates upon triggering an emergency. The communication module packages the injury level, injured location, and precise coordinates and pushes them synchronously to the backend. The command center can directly mark the location of officers in distress on the map, quickly planning rescue routes. In remote areas and isolated duty scenarios, there is no need for manual location reporting, significantly reducing search time for rescue forces. Simultaneously, coordinate information is updated with each alarm. If an officer moves after being attacked, the backend can track location changes in real time, ensuring controllable positioning throughout the rescue process. The positioning module works in conjunction with the triggering and judgment modules, continuously refreshing the location with low power consumption under normal conditions, without excessively consuming lithium battery power. The communication module integrates trauma data and positioning data for unified encrypted transmission, with 4G remote cloud upload and Bluetooth near-field synchronous push. The dual links ensure that the location information is stably delivered to the command center and surrounding police terminals, taking into account both long-distance dispatch and on-site rescue by nearby police forces. This completely solves the key problem of traditional equipment that can only sound an alarm but cannot accurately locate the distress point, thus delaying the rescue opportunity.

[0012] As a further feature of the present invention, a power supply module is also included, which is used to supply power to the system, generate a power shortage alarm when the power is insufficient, and send the power shortage alarm to the communication module. The communication module is also used to receive the power shortage alarm and send the power shortage alarm to the control center.

[0013] The advantages of this configuration are as follows: The power module utilizes a thin, flexible lithium battery adapted for use within the stab-proof vest, and is equipped with a charging and discharging protection circuit. It features multiple safety protections against overcharging, overcurrent, short circuits, and reverse connection, ensuring stable power supply even in high and low temperature outdoor duty environments and eliminating the safety hazards of battery overheating, short circuits, and fires. The power sampling circuit collects the remaining battery capacity in real time, automatically generating a low-power alarm when the power level falls below a preset operating threshold and simultaneously uploading it to the backend. The command center can remotely remind officers to charge the battery in time, preventing the device from running out of power or becoming offline during field operations. Simultaneously, the power module matches the overall low-power operating logic of the device, providing a stable low-voltage output to all modules under normal conditions, ensuring long-term standby power for the dual-layer trigger layer, conduction coil, positioning, and communication modules, meeting the needs of police officers for 24 / 7 uninterrupted duty. The power shortage early warning mechanism is a proactive equipment failure protection measure. It identifies potential power supply hazards in advance before an emergency occurs, thus avoiding the major safety risk of being unable to report an emergency due to insufficient power. The power module is lightweight and integrated, without increasing the weight of the stab-proof vest or restricting the tactical movements of police officers. It balances power safety, battery life, and wearability, and improves the overall health self-check system of the entire device, significantly enhancing the reliability of front-line duty equipment.

Detailed Implementation

[0015] Examples of embodiments of the stab-proof vest with a passive distress detection system of the present invention Figures 1 to 3 As shown: It includes a suit body 1, which is equipped with a trigger module, a judgment module, a communication module, a positioning module and a power module; The triggering module includes several sub-triggering units 2. Each sub-triggering unit 2 includes two triggering layers 22 disposed on two adjacent flexible anti-stab layers 21. Several insulating isolation particles 23 are arranged between the two triggering layers 22. The insulating isolation particles 23 are elastic and arranged in a dotted pattern. Each triggering layer 22 includes a flexible substrate, a carbon-silver composite conductive layer coated on the surface of the substrate, and a surface wear-resistant insulating protective film. The edges of each triggering layer 22 are provided with conductive contact strips for maintaining contact with the other triggering layer 22 to generate a reference signal. The flexible substrate is an aramid nonwoven composite. The TPU film, with a thickness of 0.08~0.15mm, is resistant to high and low temperatures of -40℃~70℃. The carbon-silver composite conductive layer is formed by roller coating of conductive carbon black, flake-shaped micron silver powder, and flexible polyurethane adhesive. The dotted elastic insulating particles 23 are silicone microspheres with a diameter of 0.2mm, which are hot-melt bonded to the surface of the trigger layer 22. Under normal conditions, the silicone microspheres support the two trigger layers 22 and completely separate them. When subjected to external force, the silicone microspheres are compressed and rebound, forming instantaneous surface contact. When punctured by a knife, the silicone microspheres are squeezed and permanently fail, and the two trigger layers 22 remain adhered at the puncture point. The double-layer trigger layer 22 is only conductive on the side contact strip, and the circuit resistance is maintained at a baseline of 60~80Ω. When punched or slapped, the two layers are fully bonded, and the instantaneous circuit resistance drops to 5~15Ω, with a low-resistance signal duration of ≤80ms. When a knife puncture is imminent, the two layers are continuously bonded at a local single point, and the circuit resistance is maintained at 10~20Ω, with a low-resistance signal duration of ≥300ms. The total composite thickness of the entire double-layer partitioned deformation trigger layer 22 is ≤0.3mm, and the unit area weight is <25g / ㎡. There are no hard metal components, and the original puncture resistance and impact resistance performance of the stab-proof vest are not reduced. The contact between the two trigger layers 22 will also generate location information, small area short-time contact signal, large area short-time contact signal, small area continuous contact signal, and large area continuous contact signal. The trigger module is also used to send the small area short-time contact signal, large area short-time contact signal, small area continuous contact signal, and large area continuous contact signal to the judgment module. The judgment module is used to receive location information, short-term contact signal of small area, short-term contact signal of large area, continuous contact signal of small area and continuous contact signal of large area. The judgment module generates corresponding trauma information based on the location information, short-term contact signal of small area, short-term contact signal of large area, continuous contact signal of small area and continuous contact signal of large area, and sends the trauma signal to the communication module. The communication module is used to receive trauma signals, power outage alarms, and coordinate information, and to send these signals to the control center.

[0016] The positioning module is used to generate coordinate information and send the coordinate information to the communication module.

[0017] The power module is used to supply power to the system, generate a power shortage alarm when the power is insufficient, and send the power shortage alarm to the communication module.

[0018] The sub-trigger units 2 are respectively located on the forearm, upper arm, left front chest, right front chest, upper abdomen, lower abdomen, left lower back, right lower back, and back of the garment body 1.

[0019] The sub-trigger unit 2 further includes several densely arranged conductive coils 24, which are used to generate standby signals and cut-off signals when cut off. The trigger module is used to send the cut-off signals and standby signals to the judgment module. The judgment module is used to receive the cut-off signals and standby signals. The judgment module is used to combine the cut-off signals, location information, small-area short-time contact signals, large-area short-time contact signals, small-area continuous contact signals, and large-area continuous contact signals to generate a trauma signal.

[0020] The trauma signals include strike alarm, impact alarm, stab alarm, stab wound alarm, and serious injury alarm. The strike alarm is generated by combining the location information of at least two individual sub-triggered units 2 with a large-area short-term contact signal. The impact alarm is generated by combining the large-area continuous contact signal and location information of multiple location sub-triggered units 2. The stab alarm is generated by combining the location information of a single sub-triggered unit 2 with a small-area short-term contact signal. The stab wound alarm is generated by combining the location information of a single sub-triggered unit 2 with a small-area continuous contact signal and a cutting signal. The serious injury alarm is generated by combining the location information of multiple sub-triggered units 2 with a small-area continuous contact signal and a cutting signal.
