Technical Field

[0001] This invention relates to the field of drone defense equipment technology, and discloses a vehicle-mounted integrated drone detection and defense device. Background Technology

[0002] This invention relates to the field of unmanned aerial vehicle (UAV) defense equipment technology. The vehicle-mounted integrated UAV detection and decoy system is a comprehensive countermeasure device that integrates UAV signal detection, electromagnetic interference, and navigation deception functions. It is widely used in scenarios such as public safety, emergency communications, and key area protection. This device detects and identifies UAVs by receiving their communication signals and then emits interference or decoy signals to drive them away or force them to land.

[0003] Currently, existing integrated anti-interference and anti-drone defense equipment typically adopts a single-layer or simple double-layer structure with a fixed upright antenna and mixed internal modules. This results in technical problems such as the inability to store the antenna, leading to inconvenience in vehicle deployment, and chaotic module layout causing electromagnetic crosstalk and poor heat dissipation. Summary of the Invention

[0008] In some designs, the fixed antenna assembly also includes a second antenna, which is fixedly mounted on the first mounting plate.

[0009] In some solutions, the decoy components include a housing, a four-mode decoy board, a decoy four-in-one combiner, and a decoy power amplifier module; The box has a deception cavity, with a four-mode deception board at the bottom and a deception four-in-one combiner and a deception power amplifier module at the top.

[0010] In some designs, the separator is equipped with a cable tray.

[0011] In some schemes, multiple isolated regions include a first partition, a second partition, a third partition, and a fourth partition, and the lower-level components also include: The power module is located in the first partition area; The motherboard is located in the second partition area. A bracket is fixedly installed above the motherboard, and a 5-port switch is fixedly installed on the bracket. The first radio frequency module and the third radio frequency module are respectively arranged at the bottom of the third partition area, and multiple relays are fixedly installed on the surface of the third radio frequency module. Multiple detection modules and a power divider are arranged in sequence in the fourth partition area. Detection pressure plates are fixedly installed on top of the detection modules. The power divider and multiple detection modules are arranged side by side in the fourth partition area.

[0012] In some designs, the hand-cranked rotary support platform includes a hand crank, a lead screw, a first connecting plate, a transmission component, a hinged arm, and a second connecting plate. The hand crank is connected to one end of the lead screw, and the other end of the lead screw is connected to the transmission component, which is mounted on the first connecting plate. One end of the hinge arm is hinged to both sides of the transmission component, and the other end of the hinge arm is fixedly connected to the second connecting plate.

[0013] In some solutions, the signal transceiver components include a 5G communication module, a satellite positioning antenna, a decoy transmitting antenna, a second radio frequency module, and a broadband omnidirectional antenna; The 5G communication module and the second radio frequency module are fixedly installed on the surface of the box, while the decoy transmitting antenna, satellite positioning antenna and broadband omnidirectional antenna are fixedly installed on the surface of the partition.

[0015] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention include at least the following: This application discloses a vehicle-mounted integrated detection, interference, and decoy drone detection and defense device. By setting up interchangeable inverted and fixed antenna components, the device can flexibly switch antenna configurations according to different scenarios such as vehicle transport or fixed field installation, solving the problems of traditional fixed antennas being unable to be stored and having poor scene adaptability. The housing cavity is divided into an upper cavity and a lower cavity by a partition, and the lower cavity is further divided into multiple isolated areas by a separator. With the help of wiring grooves on the separator, physical isolation of power, digital signals, and radio frequency signals is achieved, fundamentally avoiding electromagnetic crosstalk caused by multiple modules sharing the cavity, and ensuring signal stability when detection, interference, and decoy functions are operating simultaneously. At the same time, the high-power modules in the lower cavity are installed close to the bottom plate of the housing, and heat can be quickly dissipated through the metal housing, effectively improving heat dissipation efficiency. In addition, the bottom quick-mount structure allows the device to be quickly mounted on various carriers such as vehicle frames, roofs, or steps, greatly improving the on-site mobile deployment capability.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In this application, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0021] During their research on vehicle-mounted integrated detection and defense drone detection equipment, the inventors discovered the following technical problems and their causes in the structural design of existing equipment. Regarding the antenna structure, most products use fixed, upright antennas, designed to ensure signal transmission and reception gain, but without considering the storage requirements during vehicle transport. When the antenna is mounted upright on the vehicle roof, the equipment cannot be placed in the roof box or pass through height-restricted areas; if the antenna is forcibly disassembled, it needs to be reinstalled and debugged on-site, increasing deployment time and operational complexity. A few devices with folding capabilities have a folding mechanism and antenna assembly that are custom-designed as a single unit, making them incompatible with fixed antennas. This forces manufacturers to develop two separate sets of molds and assembly processes, increasing production costs and inventory pressure.

[0022] In terms of internal layout, existing equipment generally adopts a single-layer stacked structure, mixing signal transceiver modules, decoy processing modules, power supply modules, and RF modules in the same cavity. This mixed arrangement results in a lack of effective physical isolation between modules, with RF signals, digital signals, and power supply loops sharing the same cavity. Because the high-power signals emitted by the RF modules can interfere with adjacent digital circuits through spatial coupling, and the high-frequency ripple generated by the power supply modules can couple to the weak signal receiving channel of the detection module through a common ground loop, this causes severe electromagnetic crosstalk. Furthermore, due to the tight module stacking and lack of independent disassembly and assembly design, on-site maintenance requires disassembling the entire device to replace the faulty module, affecting emergency response efficiency.

[0023] In terms of heat dissipation, existing devices mostly use simple planar heat sinks without optimizing the thermal flow channels for high-heat-generating modules (such as the 5.8G third RF module and decoy power amplifier module). These high-power modules generate a lot of heat during operation, but the heat conduction path within the cavity is long and the thermal resistance is high, making it difficult to quickly transfer to the outer surface for dissipation. Long-term operation at high temperatures can lead to module performance degradation, shortened lifespan, and even overheating and system failure.

[0024] In addition, the bottom mounting structure is only designed with a single bolt fixing interface, which can only be adapted to flat mounting surfaces. It cannot meet the installation requirements of various carriers such as vehicle frames, steps, and roof platforms, which means that additional adapter brackets need to be made during on-site deployment, increasing the deployment difficulty and time cost.

[0025] The following is in conjunction with the appendix Figures 1 to 11 This application provides a detailed description of a vehicle-mounted integrated detection and defense device for unmanned aerial vehicles (UAVs) through specific embodiments and application scenarios.

[0026] Some embodiments of this application disclose a vehicle-mounted integrated detection and defense device for unmanned aerial vehicles (UAVs), including a main housing 1, an antenna assembly 2, a partition 3, an upper assembly 4, a lower assembly 5, and a quick-release structure 9.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the main housing 1 has a receiving cavity 14. The antenna assembly 2 is disposed on the outer wall of the main housing 1, including an interchangeable folding antenna assembly 11 and a fixed antenna assembly 12. The folding antenna assembly 11 includes a hand-cranked rotating support platform 110, used to switch between the working state (antenna upright) and the storage state (antenna folded). By providing interchangeable folding and fixed antenna assemblies on the outer wall of the main housing 1, the device can flexibly select the antenna configuration according to different scenarios of vehicle transport or fixed outdoor installation: for vehicle transport, the folding antenna assembly 11 is used, and the antenna is folded down using the hand-cranked rotating support platform 110, facilitating placement in the roof box or passage through height-restricted areas, while reducing wind resistance; for fixed outdoor installation, the fixed antenna assembly 12 is used to ensure signal transmission and reception stability and gain. The two antenna assemblies share the same mounting interface, allowing for quick interchange without modifying the main housing 1, avoiding the additional costs of developing two separate molds and assembly processes for the manufacturer, significantly improving the device's scenario adaptability, production economy, and usage flexibility.

[0028] like Figure 1 and Figure 5As shown, partition 3 is disposed within the receiving cavity 14, dividing the receiving cavity 14 into an upper cavity 141 and a lower cavity 142. Upper component 4 is disposed in upper cavity 141, including a decoy component 6 and a signal transceiver component 7 disposed on the exterior and / or surface of the decoy component 6. Lower component 5 is disposed in lower cavity 142, including multiple partitions 8 disposed on the bottom plate of the main housing 1, which divide lower cavity 142 into multiple mutually isolated areas. By dividing the receiving cavity 14 into upper and lower layers through partition 3, and by forming multiple physically isolated areas within lower cavity 142 using partitions 8, the functional partitioning arrangement of the signal transceiver module, decoy module, and high-power module is achieved. This layered and compartmentalized structure effectively isolates modules with different electromagnetic characteristics, avoiding electromagnetic crosstalk caused by the shared cavity arrangement of RF signals, digital signals, and power circuits. It also facilitates independent disassembly and maintenance of each module, significantly improving the electromagnetic compatibility, space utilization, and ease of maintenance of the equipment.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the fixed antenna assembly 12 includes a second antenna 120, and the inverted antenna assembly 11 has a compatible mounting bracket 13 with the fixed antenna assembly 12. The mounting bracket 13 includes a pad 130 and a first mounting plate 131. The pad 130 is fixedly connected to the main housing 1, and the first mounting plate 131 is fixedly connected to the pad 130. The second antenna 120 of the fixed antenna assembly 12 is directly fixedly mounted on the first mounting plate 131. By setting the pad 130 and the first mounting plate 131 as a common mounting interface for both antennas, the inverted antenna assembly 11 and the fixed antenna assembly 12 can be replaced without tools on the same main housing 1. The pad 130 provides sufficient mounting height and structural strength, while the first mounting plate 131 provides a flat and reliable fixing reference for the antenna. This compatible design ensures that no modification to any mounting holes on the main housing 1 is required when the two antennas are interchanged, greatly reducing production and inventory costs and the complexity of on-site modification.

[0030] like Figure 4As shown, the inverted antenna assembly 11 also includes an antenna adapter plate 111, a second mounting plate 112, and a first antenna 113. The antenna adapter plate 111 is fixedly connected to the first mounting plate 131, the hand-cranked rotating support platform 110 is fixedly connected to the first mounting plate 131, the second mounting plate 112 is fixedly connected to the hand-cranked rotating support platform 110, and the first antenna 113 is fixedly mounted on the second mounting plate 112. Through the layer-by-layer connection of the antenna adapter plate 111, the hand-cranked rotating support platform 110, and the second mounting plate 112, the inverted antenna assembly 11 forms a stable multi-level support structure. The antenna adapter plate 111, as an intermediate transition component, reduces the machining accuracy requirements of the first mounting plate 131; the hand-cranked rotating support platform 110 enables manual rotation and self-locking within the range of 0° to 90°; and the second mounting plate 112 provides a mounting surface for the first antenna 113. When storage is required, the operator manually drives the hand-cranked rotating support platform 110 to change the first antenna 113 from a vertical position to a horizontal, folded position. The entire process does not require disassembling the antenna or using any tools, which greatly improves the convenience of vehicle deployment and the speed of on-site response.

[0031] like Figure 5 As shown, the upper-layer component 4 includes a decoy component 6 and a signal transceiver component 7. The signal transceiver component 7 includes a 5G communication module 701, a satellite positioning antenna 702, a decoy transmitting antenna 703, a second radio frequency module 704, and a wideband omnidirectional antenna 705. The 5G communication module 701 and the second radio frequency module 704 are fixedly mounted on the surface of the housing 601 of the decoy component 6, while the decoy transmitting antenna 703, the satellite positioning antenna 702, and the wideband omnidirectional antenna 705 are fixedly mounted on the surface of the partition 3. By distributing different types of signal transceiver modules across the surfaces of the housing 601 and the partition 3 of the decoy component 6, both the three-dimensional space of the housing 601 and the planar space of the partition 3 are utilized, avoiding localized overheating and signal blockage caused by excessive module concentration. The 5G communication module 701 is used for long-distance data transmission within the device itself; the satellite positioning antenna 702 is used to receive positioning signals; the decoy transmitting antenna 703 is used to transmit navigation decoy signals; the second radio frequency module 704 is used to detect or interfere with drone communication in the 800-900MHz frequency band; and the wideband omnidirectional antenna 705 is used for wideband signal transmission and reception. This distributed layout ensures sufficient air gaps and electromagnetic isolation distances between modules, facilitating signal optimization and independent module replacement, and significantly improving the maintainability and signal integrity of upper-layer components.

[0032] like Figure 6 and Figure 7As shown, the decoy component 6 includes a housing 601, a four-mode decoy board 602, a decoy four-in-one combiner 603, and a decoy power amplifier module 605. The housing 601 has a decoy cavity 604. The four-mode decoy board 602 is located at the bottom of the decoy cavity 604, while the decoy four-in-one combiner 603 and the decoy power amplifier module 605 are located at the top of the decoy cavity 604. By arranging the core circuit board (four-mode decoy board 602) of the decoy function at the bottom of the decoy cavity 604, and arranging the RF combiner (decoy four-in-one combiner 603) and the power amplifier (decoy power amplifier module 605) at the top of the cavity, a compact layout with separate top and bottom sections is formed. This layout spatially separates the low-frequency control signals of the board from the high-frequency high-power signals, reducing mutual interference. Simultaneously, the decoy power amplifier module 605 is close to the top wall of the housing 601, facilitating heat conduction to the external heat dissipation structure and preventing performance degradation due to overheating of the power amplifier module. As an independent shielded cavity, the housing 601 can effectively suppress the leakage of decoy signals to other modules, thereby improving the output accuracy of the decoy signals and the overall electromagnetic compatibility.

[0033] like Figure 8 and Figure 9 As shown, the lower-level component 5 includes multiple partitions 8 mounted on the bottom plate of the main unit housing 1. Each partition 8 has a cable routing channel 15, and the partitions 8 divide the lower cavity 142 into a first partition area 16, a second partition area 17, a third partition area 18, and a fourth partition area 19. The lower-level component 5 also includes a power module 20, a motherboard 21, a bracket 22, a 5-port switch 23, a first RF module 24, a third RF module 25, a multi-channel relay 26, multiple detection modules 27, a detection pressure plate 28, and a power divider 31, each disposed within its respective partition area. The partitions 8 divide the lower cavity 142 into four isolated partition areas, and the cable routing channels 15 on the partitions 8 ensure that the power module 20, motherboard 21, 5-port switch 23, first RF module 24, third RF module 25, and detection module 27 are located in independent compartments, with necessary cable connections only through the cable routing channels 15. This compartmentalized physical isolation design fundamentally solves the electromagnetic coupling problem between the high-frequency ripple of the power module, the high-speed signals of the digital circuit, and the high-power transmission of the RF module, significantly improving the detection sensitivity and decoy signal stability of the equipment in complex electromagnetic environments. Meanwhile, the cable tray 15 ensures neat and orderly cable routing, avoiding signal crosstalk and heat dissipation blockage caused by messy cables.

[0034] Specifically, the first partition 16 is equipped with a power module 20. The power module 20 provides DC power to the entire device. By independently arranging it in a partition, it can effectively block the electromagnetic interference it generates from being conducted to other sensitive circuits, and also facilitates heat dissipation and maintenance.

[0035] The second partition 17 houses a motherboard 21, a bracket 22 mounted above the motherboard 21, and a 5-port switch 23 fixedly mounted on the bracket 22. The motherboard 21 is responsible for the overall logic control and data processing, while the 5-port switch 23 is used for internal network data exchange. Placing the motherboard 21 at the bottom, mounting the bracket 22 above it, and then mounting the 5-port switch 23 on the bracket 22 creates a compact stacked structure, fully utilizing vertical space and reducing horizontal footprint. This stacking method also allows for a short-distance cable connection between the 5-port switch 23 and the motherboard 21, reducing signal transmission loss and electromagnetic radiation.

[0036] The third partition 18 is equipped with a first radio frequency module 24, a third radio frequency module 25, and a multi-channel relay 26. The first radio frequency module 24 and the third radio frequency module 25 are respectively arranged at the bottom of the third partition 18, and the multi-channel relay 26 is fixedly mounted on the surface of the third radio frequency module 25. The first radio frequency module 24 (e.g., an 800-900MHz radio frequency module) is used for detecting or interfering with drone signals, the third radio frequency module 25 (e.g., a 5.8GHz radio frequency module) is used to block drone communication in the 5.8GHz band, and the multi-channel relay 26 provides multiple power switching and control for the third radio frequency module 25. Arranging the first radio frequency module 24 and the third radio frequency module 25 side-by-side at the bottom reduces heat accumulation between them; while mounting the multi-channel relay 26 on the surface of the third radio frequency module 25 utilizes the unused space above the third radio frequency module 25, and also allows the heat generated by the multi-channel relay 26 to be dissipated through the housing of the third radio frequency module 25, avoiding the need for additional horizontal space.

[0037] The fourth partition 19 is equipped with multiple detection modules 27, detection pressure plates 28, and power dividers 31. The detection modules 27 are stacked (e.g., the first and second detection modules are stacked vertically). The detection pressure plates 28 are fixedly installed above each detection module 27 to press and secure the stacked modules, preventing them from loosening due to vibration. The power divider 31 is arranged side-by-side with the multiple detection modules 27. By stacking the detection modules 27, horizontal space is greatly saved. The side-by-side arrangement of the power divider 31 with the detection modules 27 allows the multiple detection signals output by the power divider 31 to be transmitted to each detection module 27 over the shortest distance, reducing signal attenuation and latency. This compact and orderly layout allows the fourth partition 19 to integrate a complete detection and reception link (power divider → multi-channel detection module) within a limited area, while the detection pressure plates 28 ensure the vibration resistance and reliability of each module.

[0038] like Figure 10As shown, the quick-installation structure 9 is mounted on the base plate of the main housing 1. The quick-installation structure 9 includes a third mounting plate 904, two hanging plates 901, and an adapter post 903. The two hanging plates 901 are respectively located on both sides of the upper surface of the third mounting plate 904, each with an arc-shaped curved slot 902. The adapter post 903 is located at the center of the upper surface of the third mounting plate 904 and is used for positioning and connecting with the base plate of the main housing 1. The lower surface of the third mounting plate 904 is used for connecting with a load-bearing platform (such as roof longitudinal bars, frame crossbeams, step planes, etc.). By designing the quick-installation structure 9 as a combination of mounting plate + hanging plates + adapter post, rapid adaptation of the equipment to various load-bearing platforms is achieved. In use, the third mounting plate 904 is first quickly hooked onto the roof longitudinal bar or frame structure via the curved slot 902 of the hanging plate 901. The adapter post 903 is inserted into the positioning hole on the bottom plate of the main housing 1 for precise positioning. Then, the third mounting plate 904 is fixed to the main housing 1 with screws. This quick-installation structure allows the equipment to be installed or disassembled in seconds without the need for additional adapter brackets, making it particularly suitable for vehicle-mounted mobile deployment and temporary deployment scenarios, significantly improving on-site operation efficiency.

[0039] like Figure 11 As shown, the hand-cranked rotary support platform 110 includes a hand crank 1100, a lead screw 1101, a first connecting plate 1102, a transmission component 1103, a hinged arm 1104, and a second connecting plate 1105. The hand crank 1100 is connected to one end of the lead screw 1101, and the other end of the lead screw 1101 is connected to the transmission component 1103. The transmission component 1103 is mounted on the first connecting plate 1102. One end of the hinged arm 1104 is hinged to both sides of the transmission component 1103, and the other end of the hinged arm 1104 is fixedly connected to the second connecting plate 1105. The first connecting plate 1102 is fixedly connected to the first mounting plate 131, and the second connecting plate 1105 is fixedly connected to the second mounting plate 112. When the operator turns the hand crank 1100, the lead screw 1101 drives the transmission component 1103 to move along the lead screw axis. The transmission component 1103 pushes the hinge arm 1104, which converts the linear motion into the rotational motion of the second connecting plate 1105, thereby causing the second mounting plate 112 and the first antenna 113 to swing within the range of 0° to 90°. This mechanism achieves stable stopping at any angle through the self-locking characteristic of the lead screw, without the need for an additional locking device. Through the lead screw-hinged arm transmission mechanism of the hand-cranked rotating support platform 110, the manual antenna tilting with high torque and low operating force is realized. The operator only needs to easily turn the hand crank 1100 to smoothly raise or lower the first antenna 113, avoiding the impact and danger that may occur when directly turning the large antenna by hand, while ensuring the wind resistance stability of the antenna in the vertical working state.

[0040] It should be noted that the modules in the above embodiments (such as the 5G communication module 701, the second radio frequency module 704, the first radio frequency module 24, and the third radio frequency module 25) all adopt standardized interfaces and installation dimensions, enabling the same device to quickly replace modules of different specifications according to the frequency band requirements of different users without modifying the structure of the main housing 1 and the partitions 8. Furthermore, the main housing 1 and each partition and partition 8 are preferably made of aluminum alloy and treated with conductive oxidation, ensuring structural strength while providing excellent electromagnetic shielding effectiveness and grounding continuity. The entire device casing can be manufactured using 3D printing technology, achieving lightweight and rapid prototyping of complex curved surfaces.

[0041] The working principle of this vehicle-mounted integrated detection and interception drone defense equipment is as follows: After the device is powered on, the power module 20 in the lower component 5 supplies power to the whole machine, the multi-channel relay 26 provides stable multi-channel power switching and control for the third radio frequency module 25, and the motherboard 21 starts and loads the control program. Depending on the deployment scenario, the operator selects the inverted antenna assembly 11 or the fixed antenna assembly 12 in advance: the inverted type is selected for vehicle transportation, and the hand crank 1100 is turned to make the first antenna 113 inverted and stored; after arriving at the site, the hand crank 1100 is turned in the opposite direction, and the first antenna 113 is raised vertically to the working state through the linkage of the lead screw 1101, the transmission component 1103 and the hinge arm 1104.

[0042] In detection mode, multiple detection modules 27 in the fourth partition 19 receive antenna signals from the wideband omnidirectional antenna 705 and / or the second radio frequency module 704 via a power divider 31. The power divider 31 distributes the received signals to each detection module 27, which performs signal demodulation, spectrum analysis, and UAV identification. The identification results are then transmitted to the mainboard 21 for processing.

[0043] In jamming mode, the motherboard 21 controls the first radio frequency module 24 (e.g., 800-900MHz) and the third radio frequency module 25 (e.g., 5.8GHz) in the third partition 18 to generate high-power jamming signals in the corresponding frequency bands, based on the detection results or external commands. The jamming signals are radiated outward through their respective antennas, blocking the communication link between the drone and the remote controller, forcing the drone to hover, return to home, or make an emergency landing.

[0044] In decoy mode, decoy component 6 operates: the four-mode decoy board 602 generates simulated navigation satellite signals from multiple systems (such as GPS, GLONASS, BeiDou, and Galileo), which are then combined by the decoy four-in-one combiner 603, amplified by the decoy power amplifier module 605, and finally radiated outward through the decoy transmitting antenna 703. These false navigation signals have higher power than real satellite signals, causing the drone to receive and trust the false location information, thereby achieving the decoy driving away or forced landing of the drone.

[0045] The detection, interference, and decoy functions can operate independently or simultaneously. Because the lower-level component 5 employs a compartmentalized isolation design (the first to fourth compartments 16-19 respectively house the power supply, control, RF, and detection modules), and the partition 8 has wiring slots 15, physical isolation is achieved between the power supply circuit, digital signal circuit, and RF signal circuit. Combined with the conductive oxidation treatment of the aluminum alloy main unit housing 1, this effectively suppresses electromagnetic crosstalk, ensuring the detection module 27's receiving sensitivity during high-power interference transmission, and providing extremely low phase noise and spurious signals in the decoy signal output.

[0046] The bottom quick-installation structure 9 allows the equipment to be quickly fixed to load-bearing platforms such as vehicle roofs, frames, and steps: the lower surface of the third mounting plate 904 is attached to the load-bearing platform, and quick hanging or binding is achieved through the curved slot 902 of the hanging plate 901. After the adapter column 903 is positioned with the base plate of the main housing 1, it can be locked with screws. The entire installation process takes no more than one minute, which facilitates rapid deployment and emergency response.
