[0018] The following is a further detailed description of the specific implementation methods of the present invention, such as the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, the manufacturing process and the operation and use methods, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0019] The perceptual visualization fire extinguishing and rescue device can be applied to a helmet or a mask. The fixed part 1 is a mask or helmet with a transparent mask 3. The fixed part 1 generally has an insulation layer, and the transparent mask 3 is also made of a transparent material with insulation function. The structure and form of the mask or helmet can be adjusted as needed, and it is not repeated here for the prior art. A breathing mask 2 is generally provided in the mask and the helmet. The breathing mask 2 is located on the inner side of the transparent mask 3 and is used to cover the mouth and nose of the user (generally a firefighter). The fixed part 1 is provided with an air supply interface 4 connected to the breathing mask 2 and used to connect to the oxygen supply equipment. The oxygen supply equipment is generally carried on the back of the user and is connected to the air supply interface 4 through a pipeline interface to provide oxygen to the user, which can adapt to more disaster relief scenarios.

[0020] A socket is provided on the side or top of the fixed part 1, and the socket has a directional shape, such as a square or an oval. Because it is necessary to facilitate electrical connection with the plug, a plug that matches the socket is provided on the external sensing device 6. After the plug is plugged into the socket, the connection of the external sensing device 6 is realized, and the external sensing device 6 can be removed as needed, or a different model of external sensing device 6 can be replaced, or a damaged external sensing device 6 can be replaced. In this detachable manner, the adaptability of the device is improved.

[0021] The matching plug and socket can adopt the existing magnetic attraction structure, but because it adapts to harsh scene environments, in order to avoid detachment, the magnetic attraction structure can adopt a strong magnet (nepidium magnet), that is, a strong magnet is provided in the plug, and an iron sheet is embedded in the bottom of the socket. If the external sensing device 6 has a component that is sensitive to the magnetic field, a matching snap-on structure can be set between the socket and the plug, which can be locked by pushing in and detached by pressing to unlock. The specific structure can adopt the existing snap-on structure.

[0022] The external sensing device 6 can be electrically connected to the fixed part 1 to realize power supply and signal transmission. Therefore, a signal connector and a power connector connected to the electronic devices in the fixed part 1 are provided in the socket. The electronic devices in the fixed part 1 are connected to the external sensing device 6 through the signal connector and the power connector. The plug is provided with signal contacts and power contacts corresponding to the positions of the signal connector and the power connector. The signal contacts are connected to the processor, and the power contacts are connected to the battery. The external sensing device 6 is also the power supply point of the entire device, which is convenient for independent charging after disassembly.

[0023] The electronic devices in the fixed part 1 include a display screen 5, a speaker, and a microphone. The speaker and the microphone can be fixed by pre-embedded means and are used to record and play sounds. A display screen 5 is provided between the breathing mask 2 and the transparent mask 3 in the fixed part 1. The display direction of the display screen 5 is toward the user's eyes. The display screen 5 is inside the helmet, which can protect the display screen 5 from the influence of the external environment, and is located below the eyes, which is convenient for the user to observe with peripheral vision. Preferably, two display screens 5 are provided, symmetrically arranged on both sides of the breathing mask 2, one of which is used to display data information, and the other is used to display image information. The image information can display the front image information collected by the infrared camera to obtain images that cannot be recognized by the naked eye. The data information can be time, interactive voice letters (used when the environment is noisy), and equipment parameters (such as the remaining amount of the supply equipment, the battery power, etc.). Through the display screen 5, the interactive ability of the device is improved.

[0024] The detection direction of the external sensing unit 7 is toward the front of the fixing part 1. Because the jack and the plug have directions, the external sensing unit 7 can be reliably fixed in the front. Different types of external sensing devices 6 can be equipped with different combinations of external sensing units 7. The external sensing unit 7 can include a camera, an infrared camera, an infrared thermal imaging device, a lighting lamp, or part or all of a laser radar. Different combination devices have different functions.

[0025] For example, infrared thermal imaging devices can detect the temperature distribution inside the fire scene, predict the location of the fire source and the characteristics of high temperature distribution in advance, assist firefighters and command centers in making decisions and rescue, and improve the efficiency of search and rescue; infrared thermal imaging devices collect infrared data inside the fire scene, and after processing by the processor, the temperature distribution and high temperature point location of the fire scene can be clearly drawn, and warning information can be marked on the screen to remind firefighters to pay attention to and identify the internal situation of the fire scene, and judge the location of the fire source and the high temperature distribution in a short time, and provide a solution basis for the command personnel. Infrared cameras can recognize and judge the human body during the search and rescue process, which requires more accurate recognition; combined with human body algorithms, the distribution simulation map of human bones can be clearly identified, and combined with laser rangefinders, the specific information of trapped persons can be timely judged to facilitate rescue. By placing the display screen 5 inside the air-exhaling mask as a visualization module, the information and images inside the fire scene can be observed in time, providing auxiliary decision-making for rescue and fire fighting. AR technology can be used to magnify the picture of the pixel information through the combined lens, and the picture inside the fire scene can be presented in time to provide firefighters with more intuitive visual effects.

[0026] The combination of different external sensing units 7 on the external sensing device 6 can quickly search for trapped people in a fire or thick smoke, find out the location and distance in time, improve the rescue efficiency, and increase the survival rate of the people.

[0027] like Figure 2 As shown, the external sensing device 6 is equipped with a battery, a processor, an external sensing unit 7, a remote communication unit, a Bluetooth communication unit and a positioning unit. The external sensing unit 7, the remote communication unit, the Bluetooth communication unit and the positioning unit are all connected to the processor. The external sensing unit 7 sends the collected data to the processor for analysis. The battery supplies power to the processor, the external sensing unit 7, the remote communication unit, the Bluetooth communication unit and the positioning unit. The remote communication unit generally communicates with an external server through a 4G or 5G network, and can send information about the equipment to the server, that is, it can access the public network or through a special network, linking the front-line internal attack personnel and the command center personnel to achieve true visual interaction. The positioning unit locates the user in real time, and transmits video and signals through the 4G network and the fire self-organizing network, so that rescue and command are unified into one network, greatly improving rescue efficiency.

[0028] The Bluetooth communication unit communicates with the user's mobile phone and the oxygen supply equipment, realizing wireless communication between the oxygen supply equipment and the device, and using the device as a bridge to transmit the working parameters of the oxygen supply equipment to the display screen 5 for display. At the same time, the mobile phone can be used as an operating component of the device. After connecting with Bluetooth, the switch status and working parameters of the equipment can be adjusted. There is no need to set additional buttons on the external sensing device 6, which reduces the difficulty of packaging the external sensing device 6. A better sealing structure can be made for the external sensing device 6 to improve the watertight and airtight performance, adapt to more usage scenarios, and improve work reliability.

[0029] The device can assist internal attack team members in attack, search and rescue, fire extinguishing and evacuation, provide visual image information, and greatly improve the safety and efficiency of firefighters.

[0030] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
