Description
Technical Field
[0001] This utility model relates to the field of fire helmet technology, and in particular to an intelligent fire helmet that integrates voice control and infrared thermal imaging. Background Technology
[0002] A fire helmet consists of a shell, face shield, shoulder cape, and cushioning layer. It offers protection against impacts from sharp objects, corrosion, heat radiation, and is reflective, insulating, and lightweight. An air respirator and wireless communication system can be worn inside the helmet, and it features clearly visible reflective markings. In fire and rescue operations, complex environments with dense smoke and dim lighting are common. Firefighters rely on helmets for illumination assistance, environmental awareness, and convenient interaction to improve rescue efficiency and their own safety.
[0003] For example, Chinese patent CN220326912U discloses a fire helmet with a light display function, which includes a helmet body, a face mask rotatably connected to the front of the helmet body, a first light strip connected to the middle of the upper end of the helmet body, and grooves on both sides of the first light strip located at the upper end of the helmet body. A second light strip is installed in each of the two grooves. Through the setting of the locking component, the high-intensity flashlight is movably locked with the locking component, which can quickly realize the locking and fixing or disassembly and removal of the high-intensity flashlight. Compared with the existing fixing method, which cannot be removed, this quick-disassembly and assembly structure makes it convenient for rescuers to wear it for head lighting or manually remove it for lighting use according to the on-site environment.
[0004] However, the aforementioned lighting devices require manual activation. During the rescue process, firefighters need to continuously hold demolition tools, stretchers, and other rescue equipment with both hands, making it difficult to free their hands to operate the lighting device switch. If a sudden dark environment is encountered, the rescue equipment must be put down before the lighting can be turned on, which not only delays the rescue opportunity but may also expose them to danger due to the pause in action, resulting in a decrease in rescue efficiency and safety.

[0028] Example 1:
[0029] This utility model embodiment provides an intelligent fire helmet integrating voice control and infrared thermal imaging, such as... Figures 1-5 As shown, the helmet includes: a helmet body 1, inside which are installed a power module, a noise reduction and sound pickup module, a main control module, a first relay, and a second relay; on the outside of the helmet body 1 are installed an illumination lamp 2 and an infrared thermal imager 3; the main control module is electrically connected to the power module, the noise reduction and sound pickup module, the first relay, and the second relay respectively; the first relay is electrically connected to the illumination lamp 2; the second relay is electrically connected to the infrared thermal imager 3; a face mask 4 is rotatably installed on one side of the helmet body 1; an AR display unit is installed inside the face mask 4; the AR display unit is electrically connected to the main control module; and the main control module is electrically connected to the infrared thermal imager 3.
[0030] The working principle and beneficial effects of the above technical solution are as follows: A power module is installed inside the helmet body 1. The power module can provide stable power to the noise reduction and sound pickup module, the main control module, the first relay, the second relay, the lighting lamp 2, the infrared thermal imager 3, and the AR display unit. The positions of the power module, the noise reduction and sound pickup module, the main control module, the first relay, and the second relay can be fixedly arranged according to different structures inside the helmet body 1. The noise reduction and sound pickup module adopts an existing sound pickup module and is used to collect the user's voice information. The main control module can adopt a microcontroller or a PLC programmable logic controller. When the main control module receives the voice information collected by the noise reduction and sound pickup module, it can control the lighting lamp 2 or the infrared thermal imager. The device 3 is turned on or off. Specifically, when the user says "turn on the flashlight," the noise reduction and sound pickup module collects the voice information of "turn on the flashlight," and then the main control module controls the first relay to turn on, so that the light 2 can be powered on. When the user says "turn off the flashlight," the noise reduction and sound pickup module collects the voice information of "turn off the flashlight," and then the main control module controls the first relay to turn off, so that the light 2 can be powered off, thus realizing the control of the light 2 by sound. When the user says "turn on the thermal imaging," the noise reduction and sound pickup module collects the voice information of "turn on the thermal imaging," and then the main control module controls the second relay to turn on, so that the infrared thermal imager 3 can be powered on. When the voice prompt "Turn off thermal imaging" is heard, the noise reduction and pickup module picks up the voice information, and then the main control module controls the second relay to turn off, thus powering off the infrared thermal imager 3. This allows for voice control of the infrared thermal imager 3. In this solution, the lighting 2 is switched on by voice control instead of traditional manual operation, solving the problem of firefighters being unable to easily control the lighting device when holding equipment with both hands. This improves the speed of lighting 2 activation, avoids interruptions in rescue operations, and enhances rescue safety. Furthermore, an infrared thermal imager 3 is also installed on the outside of the helmet body 1, fixedly connected to the outer wall of the helmet body 1. The infrared thermal imager 3 can collect thermal imaging image data from the scene. The signal output terminal of the thermal imager 3 is connected to the data input terminal of the main control module, and the data output terminal of the main control module is connected to the data receiving terminal of the AR display unit. Therefore, the main control module can transmit thermal imaging image data to the AR display unit, and then display the thermal imaging image through the AR display unit. The AR display unit is located inside the face mask 4, and at least one AR display unit is provided. When the face mask 4 is lowered, the AR display unit is located directly in front of the user's eyes. Users wearing fire helmets can obtain thermal imaging images of the scene through the AR display unit. In low visibility scenarios such as dense smoke and darkness, trapped personnel can be quickly located and fire sources or high-temperature hazards can be hidden through temperature differences, further improving the accuracy and safety of rescue.
[0031] Example 2:
[0032] Based on the above embodiment 1, a wireless communication module and a speaker are provided inside the helmet body 1, and the main control module is electrically connected to the wireless communication module and the speaker respectively;
[0033] There are two speakers, which are symmetrically arranged on the inner walls of the left and right sides of the helmet body 1.
[0034] The working principle and beneficial effects of the above technical solution are as follows: The wireless communication module can adopt a Bluetooth wireless communication module, which can connect with the external command center or other firefighters' equipment to realize the transmission and reception of voice signals. When firefighters need to send voice messages, the voice information collected by the noise reduction and sound pickup module is processed by the main control module and then transmitted to the outside through the wireless communication module. When it is necessary to receive external voice signals, the wireless communication module transmits the external voice signals to the main control module, and then transmits them to the speaker through the main control module. Firefighters can then obtain external voice signals, improving team collaboration efficiency.
[0035] Example 3:
[0036] Based on embodiment 1 or 2, a loudspeaker is provided on the mask 4, and the loudspeaker is electrically connected to the main control module.
[0037] The working principle and beneficial effects of the above technical solution are as follows: The mask 4 is also equipped with a loudspeaker. When firefighters need to transmit information to trapped personnel, the noise reduction and sound pickup module first collects the firefighters' voice information, and then transmits it to the loudspeaker through the main control module. The loudspeaker converts the electrical signal into sound waves and amplifies the output to achieve long-distance transmission of voice, ensuring that trapped personnel on site can clearly hear the firefighters' voices and avoid delays in rescue due to poor communication.
[0038] Example 4:
[0039] Based on any one of Examples 1-3, such as Figure 5 As shown, mask 4 is transparent and has an arc-shaped structure.
[0040] The working principle and beneficial effects of the above technical solution are as follows: The mask 4 is made of fireproof and transparent material, which makes it easy for firefighters to directly observe the scene environment. Moreover, the mask 4 is designed with an arc structure, which makes the mask 4 fit the contour of the firefighter's face better, reduces the gap between the mask 4 and the firefighter's face, reduces the intrusion of dense smoke or toxic gases at the scene, and improves safety.
[0041] Example 5:
[0042] Based on any one of Examples 1-4, such as Figure 5 As shown, a flexible goggle 5 is provided on the inner side of the mask 4, and the flexible goggle 5 has a ring-shaped structure.
[0043] The working principle and beneficial effects of the above technical solution are as follows: A flexible goggle 5 is also provided inside the face mask 4. The flexible goggle 5 can be made of materials such as silicone or sponge. The flexible goggle 5 corresponds to the firefighter's eyes. The flexible goggle 5 can fit the firefighter's face and cover the outer periphery of the firefighter's eyes, thereby preventing smoke and other substances from entering the eyes and interfering with the firefighter's vision, ensuring the continuity of rescue actions. The AR display unit is located inside the flexible goggle 5, ensuring that the firefighter can obtain thermal imaging images. In addition, the flexible goggle 5 can reduce the firefighter's eye burns, further improving safety.
[0044] Example 6:
[0045] Based on any one of Examples 1-5, such as Figure 1 As shown, a breathing valve 6 is provided on the mask 4, and a noise reduction and sound pickup module is located inside the breathing valve 6.
[0046] The working principle and beneficial effects of the above technical solution are as follows: The breathing valve 6 adopts a one-way conduction design. When the firefighter exhales, the exhaled air can be discharged from the mask 4 through the breathing valve 6, avoiding the condensation of fog inside the mask 4 and affecting the firefighter's observation of the scene environment. When inhaling, the breathing valve 6 can block the entry of external smoke, toxic gases, etc. into the mask 4, ensuring smooth breathing. The noise reduction and sound pickup module is set inside the breathing valve 6, so that the noise reduction and sound pickup module is close to the firefighter's mouth and nose area, improving the clarity of speech and ensuring that voice control commands or communication content are accurately recognized.
[0047] Example 7:
[0048] Based on Example 6, such as Figures 1-4 As shown, an air vent plate 7 and a drive housing 8 are fixedly installed on the front side wall of the mask 4. The air vent plate 7 is located at the upper part of the mask 4. An air chamber 9 is provided inside the air vent plate 7. Several air vents 10 are provided on the lower surface of the air vent plate 7. The upper end of the air vents 10 is connected to the air chamber 9. A drive motor is provided inside the drive housing 8. The drive motor is electrically connected to the main control module through a third relay. The third relay is located inside the helmet body 1. A drive shaft 11 is provided at the output end of the drive motor. A drive disc 12 is provided on the drive shaft 11. A rotating column 13 is rotatably provided at the eccentric position on the front side wall of the drive disc 12. A drive rod 14 is provided on the rotating column 13. A piston plate 15 is provided at the upper end of the drive rod 14. The piston plate 15 is slidably connected to the inner wall of the drive housing 8 with sealing. An air inlet pipe 16 and an air outlet pipe 17 are connected to the upper end of the drive housing 8. The end of the air inlet pipe 16 away from the drive housing 8 is connected to the breathing valve 6. The end of the air outlet pipe 17 away from the drive housing 8 is connected to the inside of the air chamber 9.
[0049] The working principle and beneficial effects of the above technical solution are as follows: When using a fire helmet, if encountering dense smoke, the firefighter can emit a sound saying "turn on the motor." The noise reduction and sound pickup module collects the voice information of "turn on the motor," and then the main control module controls the third relay to turn on. After the drive motor is powered on, it starts. The rotation of the drive motor drives the drive shaft 11 to rotate, which in turn drives the drive disc 12 to rotate. The rotation of the drive disc 12 drives the rotating column 13 to rotate, and the rotating column 13 drives the piston plate 15 to reciprocate up and down inside the drive housing 8 via the drive rod 14. A first one-way valve is installed in the air pipe 16, and a second one-way valve is installed in the air outlet pipe 17. When the piston plate 15 moves downward, the gas in the breathing valve 6 flows into the drive housing 8 through the air inlet pipe 16. When the piston plate 15 moves upward, the gas in the drive housing 8 flows into the air chamber 9 of the air outlet plate 7 through the air outlet pipe 17, and then blows onto the surface of the mask 4 through multiple air outlet holes 10, blowing away some of the dust adhering to the surface of the mask 4, and also blowing away the dense smoke near the mask 4, thereby improving the cleanliness and clarity of the outside of the mask 4, making it easier for firefighters to observe the external environment through the mask 4.
[0050] Example 8:
[0051] Based on Example 7, such as Figures 1-4 As shown, a sliding hole is provided at the upper end of the drive housing 8, and a sliding post 18 is provided inside the sliding hole. The sliding post 18 is slidably connected to the inner wall of the sliding hole with sealing between the upper and lower parts. A flexible scraper 19 is provided at the upper end of the sliding post 18. The flexible scraper 19 is arranged along the length of the mask 4 and contacts the front side wall of the mask 4.
[0052] An electromagnet 20 is installed at the bottom of the sliding column 18. The electromagnet 20 is electrically connected to the main control module through a fourth relay. The fourth relay is installed inside the helmet body 1. An iron block 21 is installed at the center of the upper surface of the piston plate 15. The iron block 21 corresponds to the position of the electromagnet 20.
[0053] The working principle and beneficial effects of the above technical solution are as follows: With the drive motor started, the firefighter can issue a command to "turn on electromagnet 20." The noise reduction and sound pickup module collects this voice information, and then the main control module controls the fourth relay to open. Electromagnet 20 becomes magnetic after being energized. During the upward movement of piston plate 15, the iron block 21 on the upper surface of piston plate 15 is attracted by electromagnet 20. When piston plate 15 slides downward, it drives sliding column 18 downward. Sliding column 18 drives flexible scraper 19 to slide downward along the surface of face mask 4. With the reciprocating motion of piston plate 15, flexible scraper 19 moves up and down along the outer wall of face mask 4, thereby scraping away some impurities adhering to the surface of face mask 4. The cleanliness of the face mask 4 is improved, eliminating the need for manual cleaning by firefighters and ensuring the continuity of rescue operations. In addition, to prevent the flexible scraper 19 from interfering with the firefighters' vision due to prolonged scraping, the firefighters can issue a "turn off electromagnet 20" command. The noise reduction and sound pickup module picks up the "turn off electromagnet 20" voice information, and then the main control module controls the fourth relay to turn off. After the electromagnet 20 is de-energized, it loses its magnetism. When the piston plate 15 pushes the sliding column 18 to the highest position, the piston plate 15 separates from the lower end of the sliding column 18. Under the friction between the flexible scraper 19 and the outer wall of the face mask 4, and between the sliding column 18 and the sliding hole, the flexible scraper 19 can be kept in the upper position of the face mask 4 without interfering with the firefighters' vision, further improving the safety of the rescue.
