Therefore, discovering fires is of great significance for extinguishing them early. Built a watchtower The fire prevention monitoring system uses watchtowers to observe the occurrence of forest fires, determine the location of the fire, and report the fire situation. Its advantages are large coverage and good effectiveness. Shortcomings: Remote forest areas without living conditions cannot have observation towers; Its observation effect is limited by the terrain, with small coverage, dead corners, and gaps that cannot be observed. It cannot observe large areas of fire, residual fires, and underground fires with heavy smoke; Thunderstorm weather makes it impossible to observe from the tower; Observation is a method that relies on the experience of an observer to observe, with low accuracy and large errors. In addition, the personal safety of the lookout is threatened by lightning, wild animals, forest encephalitis, and other factors. Establish a video surveillance system The current mainstream monitoring method in China. This is a simple extension of traditional urban monitoring, which collects video images through microwave aggregation and manually completes centralized monitoring; Manual monitoring can easily cause visual fatigue, making it difficult to detect fires in videos and resulting in missed reports; There are many video lines in the monitoring center, and manual monitoring cannot monitor them one by one, which can easily lead to missed reports. So, the disadvantage of traditional video surveillance is that the false alarm rate is very high. Traditional video surveillance is a non digital system that many intelligent applications cannot achieve. Establish an intelligent warning system This is the development direction of forest fire prevention, realizing the intelligence and informatization of forest fire prevention. By utilizing seamless integration of intelligent image recognition technology, object-oriented 3D GIS technology, large-scale network monitoring technology and other high-tech, and utilizing multiple patented technologies, combined with professional knowledge of forestry management and experience in forestry fire prevention, a forestry fire prevention intelligent monitoring and early warning and emergency command system is established to achieve automatic monitoring of forest videos, accurate identification of fireworks, precise positioning of fire points, deduction of fire spread trends, auxiliary decision-making for firefighting command, post disaster assessment and other functions. A complete business chain for forest fire prevention is established, and various personalized needs of users are targeted to be solved.

Absorption of molecules in the atmosphere The signal loss of the atmospheric transmission system for LED and LD emission is mainly caused by the absorption of their transmission medium - the atmosphere. Because when a beam of light passes through a gas, there will always be a certain degree of molecular absorption. Moreover, air absorbs certain wavelengths of light particularly strongly, which cannot be used for signal transmission at all. The band where attenuation caused by atmospheric absorption is acceptable is called the atmospheric window. The data of this atmospheric transmission window band can be found in various literature, so all LED and LD systems must operate at the wavelength within this atmospheric transmission window. Absorption of particles in the air Particles in the air, such as dust and smoke, are another factor that causes absorption of light signals. Obviously, the atmosphere always contains some such particles to varying degrees, especially near water bodies, and the content of such particles is sometimes very high. In these places, it is generally advisable to install optical equipment as high as possible above the ground to improve the effectiveness of optical transmission Absorption and scattering of fog Mist is also a factor that causes severe infrared absorption, and it can also cause forward and backward scattering of light. Therefore, in foggy areas, the working hours of the optical transceiver equipment must be selected according to the local climate, as the system will not function properly when foggy. The impact of atmospheric turbulence The atmosphere has a certain degree of disorder, which not only causes signal loss, but also adds noise to the signal. Wind can cause atmospheric turbulence, which in turn can cause changes in the refractive index of air along the signal path. This phenomenon is similar to the occurrence of heat waves and mirages in areas exposed to sunlight. This effect will eventually refract the infrared beam to other directions that cannot be determined, making it impossible for the camera to capture the target being monitored.

Generally, spherical lenses may exhibit aberrations such as spherical aberration, chromatic aberration, coma, etc. Therefore, actual camera lenses usually require multiple lenses with different degrees of concavity and convexity to be grouped and combined for correction. Simple fixed focus lenses generally require 4 lenses in 3 groups, 6 lenses in 4 groups, or 7 lenses in 4 groups, while high-end zoom lenses require a combination of more than 10 lenses in 10 groups. Obviously, this not only increases the volume and weight of the lens, but also reduces the amount of transmitted light. For high-sensitivity lenses with low F-values, the larger the effective aperture, the greater the spherical aberration, and of course, the more difficult it is to correct. It is precisely due to the shortcomings of spherical lenses that non spherical lenses have been developed. The lenses used in aspherical lenses are non spherical lenses, and their surface shape is also finely adjusted based on the spherical surface shape. From a mathematical perspective, the surface shape of a sphere is a quadratic function, while the surface shape function of a non sphere is a fourth-order or even higher-order function, making the surface shape of a non sphere more complex. In fact, it is a complex non spherical surface obtained by artificially controlling the pre designed subtle surface undulations on the basis of a spherical surface. Due to the lens shape of the non spherical lens, it is precisely designed and calculated by precision instrument optical grinding, taking into account the various correction factors mentioned above. Therefore, a single non spherical lens can achieve the effect of correcting aberrations for multiple spherical lenses. In this way, non spherical lenses can effectively reduce the number of lenses, thereby reducing the volume and weight of the lens, improving transparency, accurately restoring color difference, and improving imaging quality.

Security products will be applied in various complex scenarios and harsh weather conditions. Real time monitoring around the clock places strict requirements on the portability, power consumption, processing effectiveness, and adaptability of the products. A good video fog transmission technology should integrate the technical advantages of image enhancement and image restoration based on the atmospheric transmission model, so as to achieve ideal image effects and be applied in practical engineering. After fully analyzing the advantages and disadvantages of the theory of fog penetration and conducting in-depth research and exploration, Shenzhen Anxing has developed a real-time video fog penetration technology based on the special requirements of video image fog penetration in the field of security monitoring. This technology is based on the principle of atmospheric optics, which distinguishes the depth of field and fog concentration in different areas of the image for filtering processing, and obtains accurate and natural transparent fog images. This real-time video fog transmission technology can automatically adjust according to changes in fog conditions to adapt to various scene applications, avoiding the effect of excessive blackening of close range fog transmission and blurred distant view; At the same time, it balances the efficiency and complexity of implementation, ensuring the real-time and engineering feasibility of the entire fog transmission. At the same time, this real-time video fog transmission technology can not only effectively remove the impact of fog, but also avoid color errors caused by transitional processing of certain scenes, as well as the unreal feeling caused by excessive fog removal.

However, although the clarity and intelligence level of video surveillance have improved, the demand for 24/7 clear monitoring has not been effectively realized. Currently, common infrared laser night vision devicesThe infrared light source used is mostly an 850nm LED light source, which is limited by light intensity and heat dissipation level, making it difficult to achieve night vision fill light above 80m. Therefore, nighttime monitoring capability has become a weakness of traditional surveillance cameras. Laser night vision products have the following advantages: By using laser infrared fill light technology, night vision fill light of 200 meters or even several kilometers can be achieved, which is incomparable to LED infrared light sources; The sensitivity of CCD and CMOS chips to 808nm laser is about 30% higher than that of 850nm LED. Under the same illumination, 808nm laser night vision imaging is clearer; The photoelectric conversion efficiency of semiconductor lasers is 2-3 times that of LED infrared, with lower laser energy consumption and longer lifespan.
