[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] like Figure 1-4As shown, this application provides an intelligent fire helmet, including: a shell 1, a buffer layer, a basket-type suspension device 2, a camera device 3, a laser emitter, a lighting lamp 4, an LCD display screen 8, a sensor device, a motherboard, and a battery supply module. The camera device 3, laser emitter, lighting lamp 4, LCD display screen 8, and sensor device respectively provide functions of camera recording, laser emission, lighting, screen display, and data acquisition. The shell 1 forms a hemispherical space; the buffer layer is disposed on the inner surface of the shell 1; the basket-type suspension device 2 and the motherboard are connected inside the shell 1; the camera device 3, laser emitter, and lighting lamp 4 are connected to the front ends of both sides of the shell 1; the LCD display screen 8 is connected to the front top of the shell 1; the sensor device is connected to the shell 1, located on the side or rear of the shell 1; the battery supply module is installed inside the battery mounting backplate 7 of the shell 1, which is made of carbon fiber and fixed with four M3 screws, with the battery supply module installed on its inner side. The battery supply module is electrically connected to the camera device 3, laser emitter, lighting lamp 4, LCD display 8, and sensor device; the camera device 3, laser emitter, lighting lamp 4, LCD display 8, sensor device, and battery supply module are electrically connected to the motherboard.

[0032] In a specific embodiment of this utility model, the motherboard serves as the physical carrier and connection hub for all hardware modules. The motherboard provides interfaces to integrate various sensors (such as temperature and gas sensors), display devices (such as an LCD screen 8), communication modules, and positioning modules (such as a BeiDou positioning module) on the helmet. This ensures stable power supply and data transmission between different hardware components, avoiding problems such as isolated or uncoordinated devices. The motherboard contains a processor, which is the core of data processing. It receives real-time field data collected by sensors, such as ambient temperature and CO gas concentration, and performs rapid calculations and analysis. When the motherboard detects a hazard, it can simultaneously trigger multiple modules. The motherboard uploads the processed field data (such as location and environmental parameters) to the command and management system, while simultaneously receiving instructions or map information from the command and management system.

[0033] In a specific embodiment of this utility model, the motherboard uses an STM32F407VGT6 main control chip, integrating a Cortex-M4 core with a main frequency of 168MHz, and has interfaces such as USB OTG, CAN, USART, SPI, and I2C. The motherboard is connected to each module in the following ways:

[0034] Camera module: Connects to an OV5640 RGB camera via DCM I interface and an FLI RLepton infrared camera via SPI interface; LCD display: Driven by an FSMC parallel bus to a 3.5-inch TFT-LCD with a resolution of 320×240; Sensor module: Connects to a BME688 gas sensor and a TMP117 temperature sensor via I2C bus; Communication module: Connects to a 4G module SIM7600 via USART and a StarSpark communication module via SPI; Power management: Real-time acquisition of battery voltage and current via an INA219 power monitoring chip, supporting low battery alarm.

[0035] In a specific embodiment of this invention, the laser emitter has a power of 5mW and a wavelength of 635nm, and is used for indicating dense smoke. The laser emitted by the laser emitter forms visible red dots on the smoke particles. For example, a MI LES series laser emitter can be used.

[0036] As a specific embodiment of this utility model, the lighting lamp 4 is an LED lamp used for illumination in dark environments.

[0037] As a specific embodiment of this utility model, the LCD display screen 8 is used to display the data collected by the sensor device.

[0038] like Figure 5 As shown, the battery supply module is electrically connected to the image display module and the environmental sensing module. The image display module includes an LCD screen 8, which displays images on the LCD screen. The environmental sensing module includes an infrared camera and an RGB camera, which acquire images. The environmental sensing module sends the acquired images to the image display module for display on the LCD screen 8.

[0039] As a specific embodiment of this utility model, an intelligent fire helmet also includes a communication module. The communication module connects to the motherboard via a standardized interface to ensure stable transmission of electrical signals and data. The communication module includes a 4G communication module, a 5G communication module, a Starlight communication module, a WIFI 6 module, and / or a Bluetooth communication module. The 4G and 5G communication modules are used to achieve high-speed cellular network communication, supporting real-time transmission of video, audio, and sensor data. The Starlight communication module is used for short-range high-speed data exchange between devices. The WIFI 6 module supports dual-band (2.4GHz / 5GHz) high-speed wireless local area network communication for temporary wireless local area network environments set up in camps, command centers, or fire scenes. The Bluetooth communication module is used for short-range, low-power data communication. The 4G, 5G, Starlight, WIFI 6, and / or Bluetooth communication modules together form a multi-mode, highly reliable, and low-latency communication system, ensuring that firefighters can maintain real-time and stable communication connections with the command center, teammates, and external devices in a fire.

[0040] like Figure 6 The diagram shows the communication principle of the communication module. The communication module connects to the command and management system via a base station. Uplink: The communication module communicates with the intelligent management system via the base station; downlink: The command and management system communicates with the communication module via the base station. The communication module communicates with the command and management system via the MQTT protocol, using JSON data format, and uploading once per second. The command and management system can send commands to the communication module of the intelligent fire helmet via MQTT, such as:

[0041] {"cmd":"led_on"}: Turn on the traffic lights;

[0042] {"cmd":"sos"}: Remotely trigger SOS mode.

[0043] Command transmission follows this path: Command System → Base Station → 4G / 5G Communication Module → Motherboard → Various Functional Modules. The command and management system issues commands via MQTT to the communication modules, which are then parsed by the motherboard and used to control the corresponding functional modules to execute them.

[0044] like Figure 2 As shown, the sensor device is mounted on sensor mounting area 5 on housing 1. The sensor device includes a gas sensor and / or a temperature sensor. Data collected by the sensor device is uploaded to the command and management system via a communication module (e.g., Bluetooth or 4G). The gas sensor is used to collect the CO concentration in the environment. The temperature sensor is used to collect the ambient temperature. For example, the gas sensor is a Bosch Sensortec BME688. The temperature sensor is, for example, a Texas Instruments TMP117.

[0045] As a specific embodiment of this utility model, an intelligent fire helmet also includes a Beidou positioning module; the Beidou positioning module is connected to the motherboard via a communication interface. The Beidou positioning module is electrically connected to the battery supply module and is powered by the battery supply module. The communication interface is a UART (serial port), such as the SR1097Z1 module, which by default transmits NMEA data via a TTL level UART. If the motherboard UART is RS232 level, a level conversion chip such as MAX3232 needs to be added to achieve level matching. The Beidou positioning module communicates with the command and management system via the communication module. The Beidou positioning module achieves accurate location tracking, outputting latitude, longitude, altitude, speed, and other data in real time inside and outside the fire scene. The command and management system can see the location data of each firefighter wearing a helmet on a 3D map. The selected Beidou positioning module model is EWM108-GN06B.

[0046] like Figure 2 As shown, an intelligent fire helmet also includes an indicator light 6. The indicator light 6 is a tri-color LED (red / yellow / green), 5mm in diameter, embedded in the rear of the shell 1, used to indicate the alarm status. Gas sensors and temperature sensors send the collected data to the main board. The main board compares the received data with standard data to determine whether it exceeds the standard. The main board can make decisions based on multi-source data such as gas concentration and temperature. When any data exceeds the standard, it can control the indicator light 6 to flash. The indicator light 6 can change color according to the real-time data of the gas sensor (such as a CO detector): when the concentration of harmful gas CO exceeds the standard, the red light flashes continuously; if the concentration is increasing, the red light flashes more rapidly.

[0047] As a specific embodiment of this utility model, the motherboard has built-in threshold judgment logic, as exemplified below:

[0048] Temperature threshold 80℃; if temperature ≥ 80℃, the motherboard will trigger a high temperature alarm.

[0049] The CO concentration threshold is 100 ppm. If the CO concentration threshold is ≥100 ppm, the main board will trigger a gas alarm.

[0050] Alarm response: Upon triggering, the mainboard control indicator light flashes red (1Hz), the buzzer sounds (1kHz, duty cycle 50%), and the alarm status is uploaded via the communication module;

[0051] Multi-sensor fusion: If both temperature and gas exceed the standard, it is judged as a "high-risk environment", automatically increases the upload frequency to 10Hz, and activates SOS standby mode.

[0052] like Figure 3 and 4As shown, an intelligent fire helmet also includes an SOS button 11, a power button 12, a lighting switch 9, and / or an intercom button 10; the SOS button 11, power button 12, and / or intercom button 10 are disposed on the housing 1. The power button 12 is used to establish a disconnect or connection circuit between the battery supply module pack and the load. A long press of the power button 12 powers on, and another long press powers off. After a 3-second long press of the SOS button 11 (to prevent accidental activation), the mainboard receives an interrupt signal from the SOS button 11 and controls the buzzer to sound two beeps, indicating entry into "emergency mode." The buzzer is disposed on the housing 1 and is powered by the battery supply module. A 5-second long press of the SOS button 11 (longer than the trigger time) again causes the mainboard to receive the SOS button 11 signal, and the buzzer sounds one long beep under the control of the mainboard, exiting emergency mode. Preferably, the SOS button 11 is a red waterproof button that requires a 3-second long press to trigger, preventing accidental activation. Power button 12: This is a black waterproof button. Press and hold for 2 seconds to turn on the device, and press and hold for 3 seconds to turn off the device.

[0053] In a specific embodiment of this utility model, the lighting switch 9 is connected in series in the circuit connecting the lighting lamp 4 and the battery supply module, controlling the entire circuit. When the lighting switch 9 is pressed, the lighting lamp 4 is turned on. Specifically, when the lighting switch 9 is pressed: external force pushes the moving contact to contact the stationary contact, forming a closed circuit, allowing current to flow smoothly through the lighting lamp 4, and the lighting lamp 4 lights up. When the lighting switch 9 is not pressed: the stationary contact and the moving contact inside the switch are separated, the circuit is broken, no current flows to the lighting lamp 4, and the lighting lamp 4 does not light up. The lighting switch 9 is a waterproof tactile switch, model TS-01, rated current 1A, installed on the left side of the housing 1, and connected in series with the lighting lamp power supply circuit via a wire.

[0054] As a specific embodiment of this utility model, the intercom button 10 is a PTT button, model TS-02, installed on the right side of the housing 1. Pressing it switches to transmit mode, and releasing it switches to receive mode. The intercom button 10 (usually labeled "PTT," meaning Push-To-Talk) is not simply a "switch," but triggers two key actions simultaneously: First, mode switching: When the button is pressed, the device immediately switches from "receive state" to "transmit state," shutting down the receiving circuit and starting the transmitting circuit to avoid signal interference; releasing the button automatically switches back to the receiving state, realizing the half-duplex communication logic of "press to talk, release to listen." Second, signal activation: When the button is activated, a "start command" is sent to the device's main control chip (motherboard), triggering the subsequent voice acquisition, encoding, and transmission process, equivalent to giving the device a "start speaking" signal. After the intercom's PTT button is pressed, it closes the "transmit enable switch," providing a high / low level signal to the main control chip motherboard, informing the device to "enter transmit mode." After the button is triggered, the device immediately powers the built-in microphone, which converts the user's voice (mechanical vibration) into an analog electrical signal. In this step, keeping the button pressed is crucial—as long as the button is held down, the microphone continues to collect voice data; releasing the button immediately cuts off power and stops data collection. The collected analog electrical signal is sent to the signal processing module, where it is first amplified by an amplifier and then converted into a digital signal by an analog-to-digital converter (ADC). The digital signal undergoes further encoding and compression (using proprietary intercom encoding protocols such as PMR or DMR) to reduce data volume and ensure stability and efficiency during wireless transmission. The processed digital signal is then sent to the radio frequency module, which modulates it to a preset intercom frequency (e.g., the 400-470MHz civilian band) and transmits it as radio waves via an antenna. During this process, the button must remain pressed; once released, the radio frequency module immediately stops transmitting, the device switches back to receive mode, and waits for a response. Other intercom devices (receivers) operating on the same frequency monitor the band in real time. Upon receiving the radio waves from the transmitter, they first convert the signals into electrical signals via their antennas and then send them to the demodulation module to restore them to digital signals. The digital signal is decoded and decompressed and then converted back into an analog electrical signal by a digital-to-analog converter (DAC). Finally, it is amplified by a speaker and restored to an audible sound.

[0055] As a specific embodiment of this utility model, the camera device 3 includes an infrared camera and / or an RGB camera. A 940nm long-pass filter is added in front of the lens of the camera device 3 to filter out a large amount of 800-900nm stray infrared light from the flame. An aerogel heat insulation frame is added in front of the lens of the camera device 3 to withstand high temperatures.

[0056] It should be explained that the front end of the camera device 3 has a threaded interface for mounting a 940nm long-pass filter with a diameter of 15mm and a thickness of 1mm, used to filter stray infrared radiation of 800-900nm in the flame. An aerogel heat insulation frame (silica aerogel, temperature resistant to 600℃, thermal conductivity 0.02W / m·K) is provided on the outside of the filter, which is bonded to the camera housing with high-temperature resistant silicone, with a thickness of 3mm, ensuring that the camera can operate continuously for ≥30 minutes in an environment of 150℃.

[0057] In a specific embodiment of this utility model, the battery supply module is a dual-cell lithium battery. The lithium battery is connected to components with high power demand via a boost circuit, such as lighting lamps 4 or communication modules with high power requirements. The lithium battery is also connected to components with low power demand via a buck circuit, such as sensor devices or BeiDou positioning modules with low power requirements.

[0058] It should be explained that the battery supply module consists of two 18650 lithium batteries connected in series, with a nominal voltage of 7.4V and a capacity of 2200mAh, and has the following protection functions:

[0059] Overcharge protection: Charging is cut off when the voltage is ≥8.4V;

[0060] Over-discharge protection: Output is cut off when voltage ≤ 6.0V;

[0061] Overcurrent protection: Automatic power-off when current ≥ 3A;

[0062] Temperature protection: NTC thermistor detection, charging and discharging are prohibited at ≥60℃.

[0063] As a specific embodiment of this utility model, the shell 1 is made of carbon fiber composite material. The carbon fiber composite material is, for example, T700 (carbon fiber) + PEEK (polyetheretherketone) or T700 + high-temperature epoxy material (Tg≥180℃) + external heat insulation coating. The shell 1, made of carbon fiber composite material, improves the helmet's heat resistance. The helmet shape of shell 1 is optimized based on Asian head shape data (head width 15-17cm, forehead tilt angle 15°-20°) to ensure a close fit to the head contour.

[0064] In a specific embodiment of this invention, the buffer layer is made of gradient density EPS foam material. The thickness of the buffer layer is 2-3 cm. The buffer layer covers the entire interior area of ​​the shell 1, and is integrally formed with the shell 1 through a hot-pressing process, thereby improving the helmet's impact absorption performance. The buffer layer is responsible for dispersing the impact load.

[0065] In a specific embodiment of this utility model, the basket-type suspension device 2 is fixedly connected to the housing 1 at four fixed points via four 15mm wide aramid webbing straps. The aramid webbing straps are adjusted using I TW Nexus high-temperature resistant POM sliding buckles, thus connecting the basket-type suspension device 2 to the housing 1. The four points are: corresponding to the positions above the left and right ears, the forehead, and the occipital bone. The basket-type suspension device 2 can be a commercially available suspension device; its structure will not be described in detail here.

[0066] As a specific embodiment of this utility model, the basket-type suspension device 2 is made of food-grade TPU elastic material and has an overall "hemispherical basket" structure. The basket-type suspension device 2 adopts an ergonomic interior, which is strong and comfortable to wear. The inner side uses an ergonomic buffer layer to ensure that it fits the curvature of the head and improves wearing comfort.

[0067] As an explanation, the basket-style suspension device 2 is connected to the helmet shell 1 through four fixed points (front, back, left, and right), forming a flexible frame structure similar to a basket. This layout allows the helmet's weight to be evenly distributed across the main stress areas such as the top of the head, forehead, temples, and back of the neck, avoiding concentrated pressure at a single point. Fixed suspension provides better resistance to lateral and longitudinal displacement than three-point or two-point suspension. The basket-style structure is compatible with various accessories without affecting the center of gravity balance. The basket-style suspension device 2 uses food-grade TPU elastic material to form a deformable mechanical structure; the elastic material absorbs energy upon impact.

[0068] In a specific embodiment of this utility model, a fan is added to the inside of the housing 1. The fan is electrically connected to the lithium battery, and its start and stop are controlled by the motherboard. The fan is a miniature DC centrifugal fan. Examples of miniature DC centrifugal fans include the Klein Tools 60155 and the RA-DCC133 series fans. The type of fan is not limited here; selection and installation are based on actual needs. Various small fans available on the market can also be used; their structure and principles will not be described in detail here.

[0069] As a specific embodiment of this utility model, the overall weight of the helmet is controlled within 1.8kg, which meets the requirements of national standards.

[0070] In a specific embodiment of this utility model, the camera device 3, laser emitter, lighting lamp 4, LCD display screen 8, sensor device, Beidou positioning module, communication module, intercom function module, buzzer, etc., are coordinated and scheduled through an embedded software system. The embedded software system adopts a FreeRTOS / Linux custom kernel operating system layer, implemented based on the Yocto Project, Built-droot system tools, or framework. The embedded software is based on FreeRTOS v10.4.3 and uses existing task partitioning methods, which will not be elaborated here. The coordination and scheduling of various functional modules such as the camera device 3, laser emitter, lighting lamp 4, LCD display screen 8, sensor device, Beidou positioning module, communication module, intercom function module, and buzzer are achieved through the existing FreeRTOS / Zephyr real-time operating system, integrating the open-source minmea positioning library, Bosch BSEC gas algorithm library, LVGL graphics library, paho.mqtt.embedded-c protocol stack, and MCUboot OTA framework for unified scheduling and low-power management. All software modules come from existing mature embedded operating systems, eliminating the need for self-developed core protocols, which will not be detailed here.

[0071] It should be explained that the data processing and analysis process of the intelligent fire helmet in this application is implemented through an existing embedded software system, specifically including the following software components:

[0072] Operating system layer: FreeRTOS or a custom Linux kernel (built on the Yocto Project or Buildroot).

[0073] Core software libraries and protocol stack: minmea (a lightweight open-source library): used to parse NMEA (standard communication protocol) data from the BeiDou positioning module; Bosch BSEC gas algorithm library (Bosch's official gas sensor algorithm library): used to process environmental data collected by gas sensors (such as BME688); LVGL graphics library (an open-source embedded graphics library): used to drive LCD displays and realize data visualization; paho.mqtt.embedded-c (an Eclipse open-source project that provides a C language client implementation of the MQTT protocol, designed specifically for embedded systems): used for MQTT (a lightweight publish / subscribe messaging protocol) communication with command and control systems; MCUboot OTA (an open-source secure bootloader framework): used for remote firmware upgrades.

[0074] Real-time operating system scheduling: FreeRTOS (an open-source real-time operating system) / Zephyr (a modular RTOS hosted by the Linux Foundation) is used to achieve unified scheduling and low-power management of various modules (cameras, sensors, communication, positioning, etc.).

[0075] It should be explained that the data processing and analysis of this utility model does not rely on traditional PC software, but is implemented through an embedded real-time operating system (FreeRTOS / Zephyr) combined with an open-source algorithm library and communication protocol stack, all running on the MCU or embedded processor of the helmet motherboard.
