Description

Technical Field

[0001] The present invention relates to the field of electromagnetic interference defense, and in particular to a configuration method of electromagnetic haze bomb filling materials and an electromagnetic interference method. Background Art

[0002] With the rapid development of civil aviation, airport operational safety faces more and more challenges, especially the safety hazards from bird activities. The frequent activities of bird flocks in the airport's no-fly zone can easily cause bird strikes, which in serious cases will lead to flight delays, damage to the aircraft, and even casualties. Therefore, how to effectively and intelligently drive away birds in the airport airspace has become an important issue to ensure flight safety. Currently, common bird-repelling technologies include sound waves, lasers, bionics, etc., but most methods have limited effects under complex weather conditions or large-scale bird activities, poor sustainability, and difficulty in covering specific airspace. To this end, the development of an intelligent bird-repelling equipment with good diffusion and efficient interference has become a new direction of technological development.

[0003] The following technical problems often occur in the existing bird-repelling process: First, the existing electromagnetic interference materials have a single formula, unstable interference effect, and cannot be adapted to special scenarios such as airports; Second, traditional bird-repelling methods (manual repelling, fixed-frequency sound waves) lack specificity and cannot dynamically adapt to the activity patterns of birds and weather changes. The release parameters of electromagnetic interference equipment are fixed, which easily creates interference blind spots, resulting in poor bird-repelling effects and an inability to ensure the safe operation of aviation equipment. Summary of the Invention

[0004] This summary is intended to briefly introduce concepts that will be described in detail in the detailed description below.

[0014] Optionally, the electromagnetic smog bomb forms a group of magnetic aerosol particles after being released.

[0015] The present invention has the following beneficial effects: 1. Achieves high interference and adaptability. Specifically, through the material ratio and processing method, the formulated filler material can quickly generate magnetic aerosol during the release of the electromagnetic haze bomb, forming a highly effective electromagnetic interference field, significantly enhancing the effectiveness of bird repelling or drone interference. Five different configurations are available, allowing flexible selection of filler material ratios based on actual application scenarios, enabling adaptation to different target objects (such as large bird flocks, high-altitude areas, and short-duration response scenarios), improving system deployment flexibility and environmental adaptability. All raw materials are screened to a specified mesh size before mixing to remove coarse and fine particles, improve particle uniformity and mixing efficiency, and thus ensure consistent reaction and stable atomization of the haze bomb. A staged drying process during the mixing process not only removes volatile components (such as acetone) but also achieves initial curing and structural stability of the filler material, reducing safety risks during storage and use. Fluororubber acetone is added as a binder in some configurations to enhance inter-particle adhesion, improve the structural integrity of the filler material during the launch of the electromagnetic haze bomb, and prevent premature dispersion and uneven ignition. The reasonable combination of oxygen-containing components (such as barium peroxide) and combustibles (such as aluminum powder and nitrocellulose) in the filling material can quickly release a large amount of heat and magnetic particles after detonation, achieve efficient aerosol diffusion, and effectively interfere with the navigation mechanism of birds or the perception system of drones.

[0016] 2. It achieves precise jamming, improving bird dispersal effectiveness and ensuring the operational safety of aviation equipment. Specifically, by acquiring current bird distribution information within the airport's no-fly zone and determining the optimal release point upwind based on the center of the flock's activity area, wind direction, and the effective dispersion range of the smog bomb, the system deploys the electromagnetic smog bomb at the optimal location, enhancing effective coverage and dispersal of the bird flock. By comprehensively considering current meteorological data (wind speed and direction) and the diffusion properties of the electromagnetic smog bomb, the system is adaptable to diverse weather conditions, ensuring stable and reliable release. By generating and issuing launch commands, the system can be linked to the electromagnetic smog bomb launch control terminal to automate launch operations, reducing manual intervention and improving response efficiency. The electromagnetic smog bombs are filled with a rationally proportioned material, exhibiting excellent electromagnetic interference and diffusion properties. This provides a stable physical foundation for bird repellency, effectively disrupting and dispersing bird flocks, reducing the risk of bird strikes, and ensuring the operational safety of aviation equipment within the airport.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0025] like Figure 1 FIG. 1 is a flow chart showing a method for configuring a filling material for an electromagnetic haze bomb, which specifically includes the following steps: Step 101, prepare the configuration materials of the electromagnetic haze bomb filling material, the configuration materials including barium chromate, barium nitrate, magnetic carbon powder, fluororubber acetone, polytetrafluoroethylene, barium peroxide, aluminum powder, magnesium powder and nitrocellulose.

[0026] In some embodiments, the filling materials for the electromagnetic haze bomb are first prepared. Electromagnetic haze bombs are airport security devices that release special aerosols to interfere with electromagnetic signals, used to repel birds or drones. Their core function is to generate a controllable electromagnetic interference field in the target airspace by atomizing magnetic material. The filling material refers to the functional substance carried within the bomb bay and is the core medium for generating the electromagnetic interference effect. The filling materials refer to the raw materials required to prepare the filling material and meet strict quality standards. The filling materials include barium chromate, barium nitrate, magnetic carbon powder, fluororubber acetone, polytetrafluoroethylene, barium peroxide, aluminum powder, magnesium powder, and nitrocellulose. Barium chromate is an inorganic compound, a yellow crystalline powder. Barium nitrate is a white crystalline strong oxidant commonly used in fireworks and signal flares. Here, it acts as a highly efficient oxidant, reacting vigorously with reducing metal powders (such as aluminum and magnesium powders) to produce an exothermic reaction, enhancing aerosol generation efficiency. Magnetic carbon powder refers to a carbon-based composite material with magnetic properties, typically composed of a carbon matrix (such as graphene, carbon nanotubes, or activated carbon) and a magnetic metal or oxide (such as ferroferric oxide magnetic nanoparticles). The expansion ratio of magnetic carbon powder should be no less than 50 ml / g at 1200°C, with a pH of no less than 7 and a moisture content of no more than 0.5%. The expansion ratio refers to the total amount of gas released or volume expansion (measured in milliliters) per unit mass (1 gram) of magnetic carbon powder when decomposed or burned at high temperatures (1200°C). For example, 50 ml / g indicates that each gram of material produces at least 50 ml of gas or volume expansion at high temperatures. Barium peroxide is an inorganic compound, an off-white powder. Nitrocellulose, also known as nitrocellulose nitrate, is an organic polymer compound formed by the esterification of cellulose with nitric acid. It appears white or slightly yellowish and has a cottony consistency. Fluororubber acetone is a viscous solution of fluororubber dissolved in acetone, used as a high-performance binder in electromagnetic smog bombs. Polytetrafluoroethylene is an inert polymer material with excellent heat resistance and lubricity. In smog bombs, PTFE enhances the suspension of aerosol particles and may also serve as a secondary fuel to promote high-temperature diffusion. Aluminum powder is a high-energy metal powder widely used in combustion, explosion, or heat release systems. When combined with oxidizers (such as barium nitrate or barium peroxide), it releases large amounts of heat energy, making it one of the primary fuels driving rapid smoke diffusion. Magnesium powder, like aluminum powder, is a strong reducing agent and a metal with a high calorific value. It has a low ignition temperature and burns rapidly, making it commonly used to enhance the ignition sensitivity and reaction initiation efficiency of a mixture.

[0027] Step 102: Based on the configuration materials, one of the following five configuration methods is used for configuration: Configuration method 1: 25% to 35% of barium chromate, 25% to 35% of aluminum powder, and 35% to 45% of magnetic carbon powder are mixed to obtain a first mixture; 2% to 5% of fluororubber acetone is added to the first mixture and dried to obtain a first filling material.

[0028] In some embodiments, 25% to 35% by mass of barium chromate and 25% to 35% by mass of aluminum powder are respectively sieved through 24 meshes. And 35% to 45% by mass of magnetic carbon powder is sieved through 40 meshes to improve mixing uniformity. After screening, mixing is performed to obtain a first mixture. And 2% to 5% by mass of fluororubber acetone is sieved through 16 meshes to remove undissolved fluororubber gel particles. After screening, it is added to the first mixture and dried at 50 degrees Celsius for 14 hours to stabilize the material and remove acetone residues to complete curing. Finally, the first filling material is obtained. The first filling material is one of the filling materials of the electromagnetic haze bomb.

[0029] Configuration method 2: 25% to 35% of barium nitrate, 40% to 50% of aluminum powder, and 20% to 30% of magnetic carbon powder are mixed to obtain a second mixture; 2% to 5% of fluororubber acetone is added to the second mixture and dried to obtain a second filling material.

[0030] In some embodiments, 25% to 35% by mass of barium nitrate and 40% to 50% by mass of aluminum powder are respectively sieved through 24 meshes, and 20% to 30% by mass of magnetic carbon powder is sieved through 40 meshes to ensure mixing uniformity. After screening, mixing is performed to obtain a second mixture. 2% to 5% by mass of fluororubber acetone is sieved through 12 meshes or 14 meshes, and then added to the second mixture after screening. Uniform coating is achieved by stirring and the stability of the overall structure of the material is improved. And dried at 50 degrees Celsius for 6 hours to obtain a second filling material. Among them, compared with configuration method 1, the proportion of aluminum powder is increased, which enhances the released heat value and reaction rate.

[0031] Configuration method three: 35% to 45% of magnesium powder and 35% to 45% of magnetic carbon powder are mixed and dried, and 15% to 25% of barium peroxide is added to obtain a third mixture; 5% to 10% of nitrocellulose is added to the third mixture and dried to obtain a third filling material.

[0032] In some embodiments, 35% to 45% magnesium powder by mass is sieved through a 24-mesh sieve, and 35% to 45% magnetic carbon powder by mass is sieved through a 40-mesh sieve to ensure uniform particle size. After sieving, the mixture is mixed and dried at 50°C for 8 hours. Then, 15% to 25% barium peroxide, sieved twice through a 24-mesh sieve, is added to form a third mixture. 5% to 10% nitrocellulose is sieved through a 16-mesh sieve and added to the third mixture. The mixture is then dried at 50°C for 6 hours to form a third filler material. The 16-mesh sieve (nitrocellulose) ensures consistent fiber distribution and ignition uniformity. This third filler material is specifically used to fill the core of electromagnetic haze bombs, generating magnetic aerosols and electromagnetic interference to repel birds.

[0033] Configuration method four: 15% to 25% of barium peroxide, 35% to 45% of aluminum powder, and 35% to 45% of magnetic carbon powder are mixed to obtain a fourth mixture; 2% to 5% of polytetrafluoroethylene is added to the fourth mixture and dried to obtain a fourth filling material.

[0034] In some embodiments, 15% to 25% by mass of barium peroxide and 35% to 45% by mass of aluminum powder are respectively sieved through 16 meshes, and 35% to 45% by mass of magnetic carbon powder are sieved through 40 meshes to remove coarse or fine particles, thereby improving mixing uniformity and reaction efficiency. After screening, mixing is performed to obtain a fourth mixture. 2% to 5% by mass of polytetrafluoroethylene is added to the fourth mixture after being sieved through 16 meshes, and dried at 50 degrees Celsius for 4 hours to ensure that the solvent evaporates and the water content is reduced, thereby improving the stability of the filler and the safety of the reaction, and obtaining a fourth filling material. Among them, the fourth filling material is mainly used to achieve rapid ignition and effective diffusion of electromagnetic aerosols in a short time.

[0035] Configuration method five: 15% to 25% of barium peroxide, 25% to 35% of aluminum powder, and 45% to 55% of magnetic carbon powder are mixed to obtain a fifth mixture; 5% to 10% of nitrocellulose is added to the fifth mixture and dried to obtain a fifth filling material.

[0036] In some embodiments, 15% to 25% by weight of barium peroxide and 25% to 35% by weight of aluminum powder are sieved through a 16-mesh sieve, and 45% to 55% by weight of magnetic carbon powder is sieved through a 49-mesh sieve, then mixed to produce a fifth mixture. 10% by weight of nitrocellulose is sieved through a 16-mesh sieve and added to the fifth mixture, followed by drying at 50°C for 6 hours to produce a fifth filler material. The first, second, third, fourth, or fifth filler materials are used as fillers for electromagnetic haze bombs. In practice, the material compositions and proportion ranges listed in the five configurations above are intended to illustrate preferred embodiments of the present invention and are not intended to limit the types of materials used to the specific chemical substances listed. For example, the term "oxidant" should not be construed as limited to a specific type but should include all substances with oxidizing properties. Common oxygen-containing oxidants such as barium chromate, barium nitrate, barium peroxide, and iron oxide are also suitable, as are non-oxygen-containing oxidants such as polytetrafluoroethylene and hexachloroethane. Fuels can be metal fuels such as aluminum powder, magnesium powder, and aluminum-magnesium alloy powder. Magnetic graphite powder can also be used as the haze-removing material. In practical applications, a combination of one or more oxidants can be used in conjunction with one or more fuels. Due to the varying physical and chemical properties of different oxidants and fuels, the corresponding ratio range should be adjusted based on the specific choice.

[0037] These embodiments achieve high interference and adaptability. Specifically, through the material ratio and processing, the resulting filler material can rapidly generate magnetic aerosols during the release of the electromagnetic haze bomb, forming a highly effective electromagnetic interference field, significantly enhancing the effectiveness of bird repelling or drone interference. By providing five different configurations, the filler material ratio can be flexibly selected based on actual application scenarios, enabling adaptation to different target objects (such as large bird flocks, high-altitude areas, and short-duration response scenarios), improving system deployment flexibility and environmental adaptability. All raw materials are sieved to a specified mesh size before mixing to remove coarse and fine particles, improve particle uniformity and mixing efficiency, and thus ensure consistent reaction and stable atomization of the haze bomb. The staged drying process during the preparation process not only removes volatile components (such as acetone) from the materials, but also achieves initial curing and structural stability of the filler material, reducing safety risks during storage and use. In some configurations, fluororubber acetone is added as a binder to enhance the bonding between the mixture particles, improve the structural integrity of the filler material during the launch of the electromagnetic haze bomb, and prevent premature dispersion or uneven ignition. The reasonable combination of oxygen-containing components (such as barium peroxide) and combustibles (such as aluminum powder and nitrocellulose) in the filling material can quickly release a large amount of heat and magnetic particles after detonation, achieve efficient aerosol diffusion, and effectively interfere with the navigation mechanism of birds or the perception system of drones.

[0038] In some embodiments, in order to further solve the second technical problem described in the background technology section, namely, "traditional bird-repelling methods (manual driving, fixed-frequency sound waves) lack specificity and cannot dynamically adapt to the patterns of bird activity and weather changes. The release parameters of electromagnetic interference equipment are fixed, which easily causes interference blind spots, resulting in poor bird-repelling effects and failure to ensure the safe operation of aviation equipment." In some embodiments of the present invention, for example Figure 2 FIG. 1 shows a flow chart of an electromagnetic interference method, which specifically includes the following steps: Step 201: obtaining current bird distribution information within the airport's no-fly zone. The current bird distribution information includes a plurality of bird flock activity areas and a center point corresponding to each of the plurality of bird flock activity areas.

[0039] In some embodiments, the electromagnetic interference method of the present invention is executed by a backend server. An airport no-fly zone refers to airspace around a civil or military airport where unauthorized aircraft (such as drones, paragliders, and light aircraft) are prohibited from entering. This is intended to ensure aircraft flight safety and prevent mid-air conflicts or interference. An airport no-fly zone typically includes the extensions of the runway (key areas, such as aircraft take-off and landing paths); a certain radius around the airport, typically within 5, 10, or even 15 km; and altitudes are also controlled, ranging from ground level to hundreds or even thousands of meters. Airport no-fly zones restrict not only drones but also non-man-made flying objects such as birds and kites. Because bird strikes are a major safety hazard to aircraft operations, bird removal operations are often conducted within these zones. Current bird distribution information is obtained through a radar monitoring system. The radar monitoring system's central processor analyzes the detected radar data, obtains current bird distribution information, and transmits it to the backend server. Current bird distribution information refers to the spatial distribution of bird flocks, specifically including multiple flock activity areas, the center point of each activity area, and the distribution radius of the flock. Multiple activity areas refer to multiple areas within an airport's no-fly zone frequently occupied by bird flocks. Each activity area is a circular area formed by the center point and the distribution radius.

[0040] Step 202: Obtain the current weather data of the airport and the performance parameters of the electromagnetic haze bomb. The current weather data of the airport includes wind speed and wind direction. The performance parameters of the electromagnetic haze bomb include the effective diffusion time after release. Determine the effective diffusion distance of the electromagnetic haze bomb after release based on the effective diffusion time and wind speed.

[0041] In some embodiments, current weather data is received from a weather station near the airport through various communication methods. The current weather data of the airport is the real-time atmospheric environment monitoring data of the airport, including wind speed and wind direction. Wind speed refers to the distance that air moves horizontally per unit time. Wind direction refers to the direction from which the wind comes (meteorological standard), with due north as 0. 。Clockwise measurement. The electromagnetic haze bomb performance parameters are pre-stored in the electromagnetic haze bomb information database on the backend server. These parameters are extracted from the electromagnetic haze bomb information database. These parameters include the effective diffusion time after release. The effective diffusion time refers to the duration after release from the bomb that the haze particles maintain their effective concentration and function. Multiplying the effective diffusion time by the wind speed yields the effective diffusion distance of the electromagnetic haze bomb. The effective diffusion distance refers to the distance the haze drifts and diffuses horizontally in the air after release, driven by the wind.

[0042] Step 203: According to the center point, wind direction and effective diffusion distance corresponding to each bird flock activity area, the optimal release point is determined from the upwind direction and a launch instruction is generated.

[0043] In some embodiments, the center point corresponding to each flock's activity area is a latitude and longitude coordinate. Based on this, a GIS tool (such as QGIS) is used to perform spatial calculations on the center point, wind direction, and effective diffusion distance to determine the optimal release point, which is also a latitude and longitude coordinate. Once the optimal release point is determined, a launch instruction is generated. The launch instruction contains specific parameters for controlling the launch of the electromagnetic haze bomb, such as the target location (optimal release point), launch time, and bomb type.

[0044] Step 204 : sending the optimal release point and the launch instruction to the electromagnetic haze bomb launch control terminal so that the electromagnetic haze bomb launch control terminal executes the electromagnetic haze bomb launch operation, wherein the filling material of the electromagnetic haze bomb is configured by the configuration method of claim 1 .

[0045] In some embodiments, the generated optimal release point and launch command are then sent to the electromagnetic haze bomb launch control terminal. The electromagnetic haze bomb launch control terminal is a device or system (such as a ground control console, a drone launch platform, etc.) that can receive the launch command and control the release of the electromagnetic haze bomb. Figure 3 As shown, a diagram of the data interaction architecture of the bird repellent system is shown. The optimal release point coordinates calculated in the early stage and the corresponding launch instruction data are packaged; these two pieces of information are sent / sent to the launch control end of the electromagnetic haze bomb through a communication system (such as a wireless link, a local area network or a serial port, etc.); after receiving the data, the launch control end parses the coordinates, time, type, parameters and other contents, and executes relevant control actions to control the electromagnetic haze bomb to be launched according to the instructions. Among them, the filling material of the electromagnetic haze bomb is configured by the configuration method described in claim 1. In practice, the electromagnetic haze bomb can also be used to repel drones in scenarios such as civil air defense projects. After being released, the electromagnetic haze bomb can cause shielding or interference to the drone navigation system, communication link or sensor, thereby achieving forced landing, deflection or repelling of the drone.

[0046] These embodiments achieve precise jamming, improving bird dispersal effectiveness and ensuring the operational safety of aviation equipment. Specifically, by acquiring current bird distribution information within an airport's no-fly zone and determining the optimal release point upwind based on the center of the flock's activity area, wind direction, and the effective diffusion distance of the haze bomb, the electromagnetic haze bomb is released at the optimal location, enhancing effective coverage and dispersal of the bird flock. By comprehensively considering current meteorological data (wind speed and direction) and the diffusion performance of the electromagnetic haze bomb, the system is adaptable to varying weather conditions, ensuring stable and reliable release. By generating and issuing launch commands, it can be linked to the electromagnetic haze bomb launch control terminal to automate launch operations, reduce manual intervention, and improve response efficiency. The electromagnetic haze bomb uses a rationally proportioned filling material with excellent electromagnetic interference and diffusion properties, providing a stable physical foundation for bird repellency, effectively disrupting and dispersing bird flocks, reducing the risk of bird strikes, and ensuring the operational safety of aviation equipment within airports.
