Description

Technical Field

[0001] This invention relates to the field of nuclear, biological, and chemical safety protection technology, specifically to a nuclear, biological, and chemical emergency safety protection method and system. Background Technology

[0002] In the handling of chemical, biological, and nuclear accidents (NBC response), the core accident site may be severely contaminated and damaged, and the hazardous substances and their extent are unknown. Therefore, how to effectively protect the lives of the personnel involved in the investigation is an extremely important issue.

[0003] In the event of nuclear, chemical, or biological leaks, firefighters or emergency response personnel are typically the first to arrive at the scene by vehicle. Under current conditions, the safety protection available to these personnel is limited and often simplistic, usually consisting only of chemical protective suits and self-contained breathing apparatus (SCBAs). However, reconnaissance work is a long-term, continuous task, and SCBAs have limited operational time, making it impossible to don and use them before arriving at the scene. Furthermore, reconnaissance personnel may be exposed to harmful gases before even using their SCBAs upon arrival near the accident site. On the other hand, reconnaissance work often requires personnel to walk to severely damaged core areas. During this process of donning chemical protective suits and SCBAs and walking to the accident area, the complex and dangerous conditions present constant risks of unforeseen events. Visual observation alone is insufficient to monitor the personnel's condition in real time, potentially missing crucial emergency rescue opportunities. Therefore, effectively ensuring the safety of reconnaissance personnel in areas experiencing nuclear, chemical, or biological leaks is an urgent problem that needs to be solved.

That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0064] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0065] like Figure 1 and 2 As shown, the nuclear, biological and chemical safety protection system of the present invention includes a centralized protection display and early warning device 1, an integrated filtration positive pressure device 2, an IoT air respirator device 3, a trajectory generation device 4, a vital signs collection device 5, and an emergency self-supplying oxygen isolation breathing device 6.

[0066] The integrated positive pressure filtration device 2 includes a filtration module 21, a fan booster module, a control and communication module, gas detection modules 22 and 23, and pipelines 24. Driven by the fan booster module, outside air enters the cabin through pipe 24 and filter module 21. Filter module 21 uses particulate matter, activated carbon, catalysts, ultraviolet light, and other filtration methods to remove toxic and harmful substances that may be present in the outside air. One-way valves in pipe 24 ensure unidirectional flow. Gas detection modules 22 and 23, equipped with electrochemical or other types of gas concentration sensors and dust sensors, detect whether the air after passing through the filter module contains harmful gases such as chlorine, hydrogen sulfide, and ammonia, as well as particulate matter. The integrated filtration positive pressure equipment has a set of gas detection modules on the input and output sides of the filter module, namely the first gas detection module 22 (input side) and the second gas detection module 23 (output side). The two gas detection modules are screwed to the top to avoid the influence of dust accumulation at the bottom and improve the detection effect. The control and communication module controls the operation of the fan booster module to ensure that sufficient positive pressure is maintained in the cabin, ensuring that the air entering the vehicle / cabin has only one channel through the integrated filtration positive pressure equipment. At the same time, the detection results of the gas detection modules are sent to the centralized protection display and early warning equipment via network signals.

[0067] The IoT-enabled air respirator device 3 includes an IoT data acquisition and communication module, an air cylinder, a face mask, a back support, an air cylinder valve, a pressure reducer, a breathing valve, and air connection connectors. The IoT data acquisition and communication module obtains the air pressure inside the air cylinder through the air cylinder valve, obtains the breathing frequency through the breathing valve, and detects the presence of toxic or harmful substances in the air inside the face mask. The IoT data acquisition and communication module transmits the collected information wirelessly to a centralized protection display and early warning device.

[0068] The trajectory generating device 4 includes a location positioning module, an inertial navigation module, a magnetic module, and a trajectory communication module. The trajectory communication module integrates the latitude and longitude information from the location positioning module, the acceleration information from the inertial navigation module, and the magnetic direction information from the magnetic module to obtain the specific location, trajectory, and gait frequency. This information is then transmitted wirelessly to the centralized protection display and early warning device. During use, the trajectory generating device 4 is secured to the back support of the IoT air respirator device 3 using clips to ensure relative stability of the device facing the ground.

[0069] The vital signs data acquisition device consists of five modules: a temperature acquisition module, a pulse acquisition module, a blood oxygen acquisition module, a display and communication module, a vibration module, an external speaker module, and a fastening strap. The display and communication module integrates the temperature, pulse, and blood oxygen saturation information collected by the other modules, displays it, and transmits it wirelessly to a centralized protection display and early warning device. Upon receiving an alarm message from the centralized protection display and early warning device, it controls the vibration and external speaker modules to activate and alert the investigators. The vital signs data acquisition device is worn on the wrist of the investigator for easy viewing.

[0070] The centralized protection display and early warning device 1 includes a computer (e.g., desktop, all-in-one, or laptop), a structural frame, human-computer interaction devices (e.g., mouse, keyboard, etc.), an integrated communication module, and indicator lights. The centralized protection display and early warning device 1 communicates with the integrated positive pressure filtration device 2 via the integrated communication module to control its operation and acquire information on the composition of toxic and harmful substances in the vehicle / cabin's interior and exterior air collected by the integrated positive pressure filtration device. The centralized protection display and early warning device 1 also communicates with the IoT-enabled air respirator device 3, trajectory generator device 4, and vital sign acquisition device 5 via wireless communication (LORA or NB-IoT, etc.) through the integrated communication module to acquire relevant safety protection information for these personnel and issue commands based on the safety protection situation. Finally, the centralized protection display and early warning device communicates with the emergency self-supplying oxygen isolation breathing device 6 via wireless communication (LORA or Zigbee, etc.) through the integrated communication module to acquire oxygen supply time information.

[0071] The centralized protection display and early warning device 1 acquires data from the IoT-enabled air respirator device 3, trajectory generator device 4, and vital sign acquisition device 5 according to a dynamic communication cycle and priority communication method. Using the information from the trajectory generator device 3, the centralized protection display and early warning device 1 generates the real-time movement route and trajectory of the reconnaissance personnel outside the vehicle / cabin. If the distance between the reconnaissance personnel and the vehicle / cabin exceeds the safe distance, the centralized protection display and early warning device proactively issues a warning message, and the vital sign acquisition device 5 prompts the reconnaissance personnel to retreat via voice / vibration / display. Using the data from the vital sign acquisition device 5 and the IoT-enabled air respirator device 3, the centralized protection display and early warning device 1 displays and analyzes the reconnaissance personnel's body temperature, pulse, blood oxygen saturation, gait frequency, respiratory rate, and working duration in real time, proactively generating a safety and health index for the reconnaissance personnel. If any vital sign value or health index of the reconnaissance personnel exceeds the normal range, the centralized protection display and early warning device 1 proactively issues a warning message, and the vital sign acquisition device 5 requests the reconnaissance personnel to retreat via voice / vibration / display. Based on the cylinder pressure data of the IoT-enabled air respirator device 3, the centralized protection display and early warning device 1 actively calculates the remaining gas volume and estimated usage time of the cylinder, and uses a safe dynamic gas volume alarm method to actively issue a warning message when dangerous conditions are reached. The vital signs collection device requests the detection personnel to retreat via voice / vibration / display.
