[0002] Firefighter protective clothing is specialized equipment designed to protect the body from flames and radiant heat. The materials used for easy-to-wear firefighting protective clothing, in addition to meeting high strength and abrasion resistance requirements, vary depending on the purpose and principle of protection. These materials range from natural materials like cotton, wool, silk, and lead, to synthetic materials like rubber, plastic, resin, and synthetic fibers, to modern, functional materials and composite materials. Currently, firefighting protective clothing is the most commonly used personal protective equipment in firefighting brigades and is also the most frequently used.
[0003] Firefighters struggle to dissipate body heat effectively in a fire, making them susceptible to hyperthermia, heatstroke, and other conditions. Current firefighting uniforms rely on simple insulation and simple cooling methods to block external heat. These lack effective means to regulate the heat generated by firefighters themselves, leading to a significant consumption of cooling resources during temperature regulation. This can hinder subsequent firefighting efforts due to insufficient cooling resources. Therefore, a comprehensive intelligent temperature control and alarm system for firefighting uniforms based on multi-source sensor fusion is needed. Summary of the Invention

The gas acquisition module collects data on the concentration of combustible and toxic gases at the fire scene. The location acquisition module locates the firefighter's geographic location and generates data in real time. The physiological status acquisition module monitors the firefighter's physiological status and generates data. The data output module classifies and outputs these collected data. Step 2: The data processing module in the alarm system receives the data transmitted by the data acquisition system, performs statistical and classification processing on it, and the data monitoring module monitors the processed data in real time and determines whether the data exceeds the normal range based on the pre-set data threshold. If any data extreme value exceeds the threshold, the corresponding abnormal signal is output; Step 3: The physiological status alarm module receives the firefighter's physiological status abnormality signal from the data monitoring module.

At the same time, the communication construction module builds a communication channel with teammates and the fire headquarters, making it convenient for people inside and outside the fire scene to communicate and report on the situation. Step 7: The visualization data in step 6 is uploaded to the server by wireless transmission through the individual status sharing system to transmit the individual status information of the firefighter wearing the fire suit. The firefighter's teammates and the fire headquarters can obtain this information from the server through the corresponding terminal equipment to understand the individual situation of the firefighter in a timely manner.

The external fire temperature is used as the reference point. According to the changes of the reference point, the thresholds of various data are dynamically adjusted. The data with the extreme values of various data exceeding the threshold are used for hazard level assessment. The hazard level assessment outputs the corresponding score and unifies the comprehensive score.

The location acquisition module locates the firefighter's geographic location and generates data in real time. The physiological status acquisition module monitors the firefighter's physiological status and generates data. The data output module classifies and outputs these collected data. Step 2: The data processing module in the alarm system receives the data transmitted by the data acquisition system, performs statistical and classification processing on it, and the data monitoring module monitors the processed data in real time and determines whether the data exceeds the normal range based on the pre-set data threshold. If any data extreme value exceeds the threshold, the corresponding abnormal signal is output; Step 3: The physiological status alarm module receives the firefighter's physiological status abnormality signal from the data monitoring module. When abnormal physiological conditions such as abnormal blood pressure and pulse occur, it outputs a corresponding "physiological abnormality alarm" signal and alerts the firefighter through voice broadcast; Step 4: The temperature anomaly alarm module receives abnormal signals from the firefighter's body temperature, the firefighter's suit temperature, and the temperature of the space the firefighter is in. If the firefighter's body temperature is too high, it outputs a "Level 1 High Temperature Alarm" signal to remind the firefighter to pay attention to their body temperature. If the firefighter's suit temperature is too high, it outputs a "Level 2 High Temperature Alarm" signal to warn the firefighter that the suit may be exposed to temperature risks. If the temperature of the space the firefighter is in is too high and reaches an emergency level, it outputs an "Emergency Alarm" signal. Step 5: Based on step 4, the first-level high temperature alarm corresponds to the activation of the first-level cooling module, the second-level high temperature alarm corresponds to the activation of the second-level cooling module, and the emergency cooling module corresponds to the activation of the emergency cooling module, and the corresponding cooling method is used according to the situation; Step 6: When in the fire scene, the collected data is visualized using the fire scene data visualization module. The data output by the data collection module is then displayed on the visualization panel inside the firefighting suit. At the same time, the communication construction module builds a communication channel with teammates and the fire headquarters, making it convenient for people inside and outside the fire scene to communicate and report on the situation. Step 7: The visualization data in step 6 is uploaded to the server by wireless transmission through the individual status sharing system to transmit the individual status information of the firefighter wearing the fire suit. The firefighter's teammates and the fire headquarters can obtain this information from the server through the corresponding terminal equipment to understand the individual situation of the firefighter in a timely manner.
