Description

Technical Field

[0001] This application relates to the technical fields of reconnaissance equipment and personal protection, and specifically relates to a multi-sensor fusion helmet that enhances detection effects, aiming to improve the user's situational awareness of the surrounding environment by fusing various sensor information. Background Art

[0002] Currently, helmet-mounted night vision technology mainly realizes observation under night or low-light conditions through image enhancement technology, infrared imaging technology, multi-spectral fusion technology, and intelligent image processing technology. Image enhancement technology relies on an Image Intensifier Tube (IIT), which magnifies weak visible light signals, enabling users to observe targets under low-light conditions. Infrared imaging technology uses the infrared radiation emitted by objects to form images, especially suitable for completely dark or smoky environments. Multi-spectral fusion technology integrates image information in different bands such as visible light and infrared to improve the details and contrast of images and enhance target recognition ability. Intelligent image processing technology analyzes and processes images with advanced algorithms and artificial intelligence technology to achieve functions such as target recognition and tracking. In addition, to improve the user experience, some night vision devices are integrated with helmets to reduce weight, improve comfort, and facilitate operation.

[0003] Although the existing helmet-mounted night vision technology meets the needs of users to a certain extent, there are still the following deficiencies: First, under extremely low-light conditions, the effect of image enhancement technology is limited. Especially in completely dark or smoky environments, the image quality drops significantly. Second, although infrared imaging technology can work in completely dark environments, the resolution and detail clarity are usually not as good as visible light images. And although cryogenic infrared detectors can provide higher resolution and detection range, their power consumption is large and an additional cooling system is required, increasing the complexity and weight of the device, limiting the portability and battery life of the device. At the same time, high-end infrared detectors and cooling systems are expensive, making the overall cost of the device remain high, which greatly restricts its wide application in the civilian field. Third, although multi-spectral fusion technology can increase the information content of images, in practical applications, the complexity of the fusion algorithm and the demand for computing resources are relatively high, which may lead to insufficient real-time performance and affect the user experience. Fourth, there are still deficiencies in the human-computer interaction of existing helmet-mounted night vision devices. Operations such as adjusting the viewing angle and replacing the battery are not convenient enough, affecting the user experience. In some extreme environments (such as strong light, high temperature, or low temperature), the existing night vision devices may experience a decline in performance, reducing the reliability of the devices.

[0004] In summary, although the prior art has to some extent solved the problem of observation in night and low-light environments, there are still deficiencies in aspects such as viewing angle, visual fatigue, tactical movement compatibility, chemical warfare protection, and environmental adaptability. Therefore, it is of great significance to develop a multi-sensor fusion helmet that can overcome the above-mentioned defects and enhance the detection effect. Summary of the Invention

[0005] The purpose of this application is to provide a multi-sensor fusion helmet that enhances the detection effect, so as to solve the defects of helmets in the prior art in aspects such as viewing angle, visual fatigue, tactical movement compatibility, chemical warfare protection, and environmental adaptability.

[0006] To achieve the above purpose, the following technical solutions are adopted in this application: This application discloses a multi-sensor fusion helmet that enhances the detection effect, which includes a helmet shell; a thermal fusion night vision device, which is fixed on both sides of the top of the helmet shell and is used for environmental image acquisition; a digital display goggle, which is adjustably installed on the helmet shell and is electrically connected to the thermal fusion night vision device; a communication device, which is fixed on the helmet shell; a protective face mask, which is installed on the opening side of the helmet shell, and the protective face mask and the helmet shell form a cavity for accommodating the human head; a gas monitor, which is fixed on the helmet shell.

[0009] In a further aspect, a limit buckle is provided on the helmet shell, and the bridge of the nose on the digital display goggle moves into contact with the limit buckle.

[0010] In a further aspect of this application, the communication device includes a microphone and an earphone, the earphone is fixed on the helmet shell, and the earphone is electrically connected to the microphone.

[0011] A further solution of the present application is that the gas monitor includes a civilian gas monitoring module and a military gas monitoring module.

[0012] A further solution of the present application is that the protective mask is provided with a breathing mask, a gas filter cartridge, and a high-pressure oxygen cartridge. The breathing mask, the gas filter cartridge, and the high-pressure oxygen cartridge are connected in sequence. A connecting pipe is provided on the lower side of the breathing mask, and a sealing cover is provided on the side of the connecting pipe away from the breathing mask.

[0015] The beneficial effects of the present application are as follows: In the present application, the imaging result of the distributed helmet shell thermal fusion night vision device is transmitted to the digital display goggles through a circuit and displayed on the digital display goggles, avoiding the sight line of the user being blocked by the lens barrel and the imaging tube. The user can take into account the situation inside the eyepiece and the situation within a short distance.

[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are only a part rather than all of the embodiments of the present application. The following description of at least one exemplary embodiment is actually illustrative only and in no way restrictive of the present application and its application or use.

[0020] As Figure 1 and Figure 2 shown, a fusion helmet for enhancing detection effect is disclosed in this embodiment, which includes a helmet shell 1, a thermal fusion night vision device 2, digital display goggles 3, a communication device 4, a protective face mask 5, and a gas monitor 6. The thermal fusion night vision device 2 is fixed on both sides of the top of the helmet shell 1 for imaging external things. The digital display goggles 3 are adjustably installed on the helmet shell 1 and are electrically connected to the thermal fusion night vision device 2. When in use, the thermal fusion night vision device 2 records external things into a video and transmits the signal to the digital display goggles 3, which are presented to the user.

[0021] As shown in the attached Figures 3 to 5 figure, in some embodiments, the design of the fusion helmet for enhancing detection effect is realized as follows. The thermal fusion night vision device 2 is a key component of the helmet, which integrates a variety of advanced imaging technologies to achieve high-quality observation at night or in low-light conditions. The thermal fusion night vision device 2 includes a multi-source supplementary light flashlight 21, an ultraviolet light imager 22, a low-light night vision device 23, an infrared thermal imager 24, and an operation panel 15. The multi-source supplementary light flashlight, the ultraviolet light imager 22, the low-light night vision device 23, and the infrared thermal imager 24 are connected to the operation panel 15 through a circuit sleeve and are connected to the helmet shell 1 through connecting wires. The operation panel 15 is connected to the digital display goggles 3 through a digital display circuit 13. The digital display circuit 13 is fixed by a fixed buckle to prevent the circuits from being entangled or interfering with each other, and at the same time improve the anti-damage ability.

[0022] Among them, the multi-source fill light flashlight 21 includes three light sources: visible light, polarized light, and near-infrared light. Appropriate light sources can be selected according to different environmental requirements for fill light to improve the clarity and contrast of images. A flashlight button 14 is provided on the multi-source fill light flashlight 21 for turning on / off or switching different light sources; the ultraviolet imaging device 22 uses ultraviolet imaging technology and can provide clear images in a completely dark environment, suitable for night reconnaissance and target recognition. The ultraviolet imaging device 22 irradiates the target with ultraviolet light. Due to the characteristics of ultraviolet light, it can excite certain substances (such as certain types of paints, oils, pollutants, etc.) to produce a fluorescence effect, that is, under ultraviolet light irradiation, these substances will emit visible light. By capturing the visible light generated by these fluorescence effects, the ultraviolet imaging device 22 can generate clear images. In addition to night reconnaissance (in a completely dark environment, the ultraviolet imaging device 22 can generate images by capturing the fluorescence effect on the target surface, thus realizing night reconnaissance and target recognition), it can also be used for target recognition (through ultraviolet imaging technology, subtle differences that are not easily detected under visible light conditions can be identified, such as the distribution of specific substances, the degree of pollution, etc.); the low-light night vision device 23 amplifies weak visible light through image enhancement technology and is suitable for observation under low-light conditions; the infrared thermal imager 24 forms images using the infrared radiation emitted by objects and is particularly suitable for observation in completely dark or smoky environments; in a further embodiment, the operation panel 15 includes several buttons 14 such as "switch", "mode", "refresh", "auto", etc., which are used to control functions such as turning on / off the device, switching imaging modes, adjusting the image refresh rate, and enabling automatic adjustment.

[0023] As shown in the Figure 3 attachment, a first connecting shaft 33 is provided in the middle of the digital display goggles 3, so that the lenses 31 of the two goggles are connected by the first long connecting shaft, and at the same time, a certain angle of rotation can be realized, so that the digital display goggles 3 can fit more closely to the user's face. On both sides of the digital display goggles 3 (the separated ends of the two lenses 31), a second connecting shaft 32 is provided on each side. The second connecting shaft 32 is connected to the helmet shell 1 through an anti-dropping elastic band 34. Here, a limit buckle 11 is provided above the helmet shell 1. When the digital display goggles 3 are not needed, the digital display goggles 3 can be set on the upper side of the helmet shell 1 through the anti-dropping elastic band 34, and the bridge of the nose on the digital display goggles 3 moves into contact with the limit buckle 11, and the limit buckle 11 can effectively prevent the digital display goggles 3 from slipping. During use, the technical functions of the digital display goggles 3 are as follows: Display technology: Adopting a high-resolution display technology, it can present clear and delicate images, uses target detection technology to detect targets within the field of view, and uses image enhancement, edge detection, and prominent contours to reduce visual fatigue.

[0025] Protection function: It has built-in protection measures such as anti-fog, anti-scratch, and anti-UV (ultraviolet light), which can extend the device life and ensure that the image clarity is not affected. For users, the digital display goggles 3 are reinforced by an anti-dropping elastic band 34 to prevent dropping, and at the same time can tightly adsorb on the skin around the eyes to protect the part within the positive projection range of the goggles from being contaminated by poisonous gases, unknown water bodies (during swimming operations), etc.

[0026] Compatibility: It is well compatible with the thermal fusion night vision device 2, the protective mask 5 and other accessories, ensuring smooth cooperation during use and improving the reliability and usability of the overall system.

[0027] The communication device here includes a microphone 41 and an earphone 42. The earphone 42 is fixed on the helmet shell 1. The earphone 42 is electrically connected to the microphone 41. The earphone 42 is used for communication to ensure good communication quality even at night or under low light conditions. A number of buttons 14 are provided on the earphone 42. The earphone 42 is connected to the microphone 41 through a deformable connecting tube 511 (with a communication circuit placed inside).

[0028] As shown in the Figure 2 attachment, the gas monitor 6 is used to detect harmful gases in the surrounding environment to ensure that users can take timely protective measures in a chemical warfare environment. The gas monitor 6 is arranged at the rear of the helmet and is fixed to the rear side of the helmet through 4 fixing brackets.

[0050] Military gas monitors 6 usually pay more attention to use in extreme environments, such as detecting chemical and biological warfare agents on the battlefield to protect users from harm.

[0051] In a further embodiment, continue to observe the attachment Figure 3 , a breathing mask 51 is provided in the middle of the protective mask 5. Breathing filters 57 are provided in the upper middle and lower middle parts of the breathing mask 51. The breathing mask 51 is connected to the gas filter cartridge 52 and the high-pressure oxygen cartridge 53 respectively through the two side air inlet pipes 54. One gas regulating valve 55 is provided on each of the two side air inlet pipes 54. A gas filtering screen 56 is provided on one side of the gas filter cartridge 52 for initially screening out large particulate matters (such as dust, etc.) in the air. A connecting pipe 511 is provided on the lower side of the breathing mask 51, and a sealing cover 512 is provided on the other side of the connecting pipe 511. When the sealing cover 512 is opened, the user can drink water, take energy gels or supplementary liquid foods by inserting a hose into the connecting pipe 511; when the gas filter cartridge 52 fails, the user is in a state of intense running or in an environment of pure carbon monoxide, carbon dioxide, etc., since sufficient oxygen cannot be obtained from the air, the user can close the gas regulating valve 55 of the air inlet pipe 54 on one side of the gas filter cartridge 52 and simultaneously open the gas regulating valve 55 of the air inlet pipe 54 on one side of the high-pressure oxygen cartridge 53 to ensure sufficient oxygen supply.

[0052] In addition, it should also be noted that in the battlefield environment, the kill probability is affected by many complex factors, including weapon type, weapon power, shooting distance, shooting angle, quality of protective equipment, battlefield environment (such as terrain, shelters), soldiers' reaction and evasion abilities, etc. Generally, the kill probability of the exposed area of personnel is as shown in the following table.

[0053]

[0054] Accurately calculating the kill probability is very complex and involves many factors, but it can be approximately calculated through a simplified formula; the calculation formula is as follows: P = w × m × b × l Wherein, w is the weapon kill efficiency coefficient; different weapons have different kill efficiencies, such as rifles, machine guns, artillery shells, etc.; m is the hit accuracy coefficient; it is related to the shooter's skills, environmental conditions (such as wind speed, distance, etc.); b is the exposure time coefficient; the length of time a person is exposed to danger; l is the exposed area coefficient; a coefficient set according to different exposed areas; ① In the thermal fusion night vision goggles or imaging tube of the present invention, they are arranged on the upper side of the helmet, which conforms to the situation of "only the upper side of the helmet or up to the eyebrows being exposed". Assuming the weapon killing efficiency coefficient is 0.8, the hit accuracy coefficient is 0.6, the exposure time coefficient is 0.5, and the exposed area coefficient is 0.2, then the killing probability is approximately:

[0055] ② For traditional night vision goggles, the lens barrel or imaging tube is arranged in front of the user's eyes, which conforms to the situation of "most of the helmet being exposed or down to the lower side of the eye socket". Assuming the other coefficients remain unchanged and the exposed area coefficient is 0.5, then the killing probability is approximately:

[0056] Since , the structural position design of the thermal fusion night vision goggles in the present invention can effectively reduce the probability of the user being killed, enabling the user to effectively observe the enemy situation when only the upper side of the helmet or up to the eyebrows is exposed, and improving the user's own survival rate.

[0057] By arranging the lens barrel or imaging tube of the thermal fusion night vision goggles on the upper side of the helmet, rather than placing these components in front of the user's eyes as in traditional night vision goggles, the exposed area of the user during use is significantly reduced, thereby reducing the probability of being hit by enemy fire.
