Description

Technical Field

[0001] This application relates to the field of data transmission, and more particularly to a data transmission device. Background Technology

[0002] Unpredictable factors such as typhoons, earthquakes, and material aging can directly affect antenna attitude, thereby impacting signal coverage and causing problems such as poor call quality and insufficient call absorption. This severely affects network performance and increases customer complaint rates. Current technologies primarily rely on mechanical compasses and traditional parameter surveys to check antenna attitude. However, mechanical compasses have significant limitations in high-altitude measurements, making accurate measurements difficult. Traditional parameter surveys suffer from inaccuracies, error-proneness, and limited controllability. To address this issue, precise antenna parameters are acquired through data transmission equipment, enabling antenna adjustments.

Similarly, for clarity and brevity, some descriptions of well-known functions and structures are omitted in the following description.

[0022] Figure 1 This is a schematic diagram of the structure of a data transmission device provided in an embodiment of the present utility model. Figure 1 As shown, the data transmission device includes a positioning module, a low-level driver module, and an application layer module. The positioning module has a cuboid-shaped housing with an RS232 interface. The positioning module is connected to the RS232 interface and communicates with the low-level driver module through the RS232 interface. The low-level driver module is also electrically connected to the application layer module. A metal shielding cover is provided around the RS232 interface. The metal shielding cover is rectangular and is fixed to the housing of the positioning module with screws.

[0023] In this embodiment of the invention, the data transmission device consists of a positioning module, a low-level driver module, and an application layer module.

[0024] The positioning module's outer casing is rectangular in shape, specifically 50mm in length, 30mm in width, and 20mm in height. The casing is made of metal, providing excellent electromagnetic shielding and mechanical strength to protect the internal components.

[0025] An RS232 interface, a standard 9-pin D-type connector, is located on one side of the positioning module's housing. A rectangular, box-shaped metal shield, 40mm long, 25mm wide, and 15mm high, is tightly fitted around the interface. Made of stainless steel with a thickness of 0.5mm, the shield is secured to the positioning module's housing using screws made of stainless steel, 2mm in diameter and 8mm in length, located at the four corners of the shield. This ensures a stable installation and effectively reduces electromagnetic interference affecting RS232 communication.

[0026] The underlying driver module is in the form of a rectangular circuit board, 100mm long, 80mm wide, and 1.6mm thick, made of epoxy resin glass cloth. Various electronic components, such as resistors, capacitors, and chips, are distributed on the circuit board. These components are connected via solder pads and are evenly distributed across the board to enable the various functions of the underlying driver module. Multiple circular mounting holes, 3mm in diameter, are provided along the edge of the circuit board. Screws, also made of stainless steel, 3mm in diameter and 10mm long, are used to secure the circuit board to specific locations within the device housing, ensuring a firm and accurate installation.

[0027] The underlying driver module connects to the RS232 interface of the positioning module via an RS232 data cable. One end of the RS232 data cable has a 9-pin D-type connector that matches the RS232 interface of the positioning module, and the other end has a 9-pin D-type socket that matches the corresponding interface on the underlying driver module's circuit board. The data cable core is made of multi-strand twisted tinned copper wire with a diameter of 0.5mm. The core is wrapped with a shielding layer made of aluminum foil with a thickness of 0.1mm, and the outermost layer is an insulating sheath made of black polyvinyl chloride with a thickness of 0.8mm. The plugs and sockets at both ends of the data cable have 10mm long metal braided tails at the cable connection points to enhance the cable's tensile and bending resistance, ensuring the stability and reliability of data transmission.

[0028] The application layer module is encapsulated in a separate square box-shaped housing with a side length of 60mm. The housing is made of fire-retardant plastic, providing excellent insulation and flame retardancy. The application layer module is electrically connected to the underlying driver module via an interface on the circuit board. The connection uses a ribbon cable with a wire core diameter of 0.3mm and an insulation layer thickness of 0.5mm. Both ends of the ribbon cable connect to the circuit boards of the underlying driver module and the application layer module via connectors. These connectors are pin-mount connectors with a pin pitch of 2.54mm, ensuring the reliability and stability of the electrical connection.

[0029] In this embodiment, a data transmission device is constructed through the specific structure and connection method of the above modules. This device enables data transmission between the positioning module and the underlying driver module, as well as electrical connection and data interaction between the underlying driver module and the application layer module. At the same time, the metal shielding covers reduce the impact of electromagnetic interference on RS232 interface communication, ensuring the accuracy and stability of data transmission. This ensures that the positioning module accurately collects antenna parameter data and transmits it accurately to the application layer module for processing via a stable communication link, thus guaranteeing the accuracy of antenna parameter acquisition.

[0030] In the above Figure 1Based on the above, this embodiment of the invention also provides a structural schematic diagram of a data transmission device. (See diagram below.) Figure 2 As shown, the bottom-level driver module is a circuit board structure. The bottom-level driver module is rectangular and made of epoxy resin glass cloth board. The bottom-level driver module has multiple pads for connecting different components, which are evenly distributed on the bottom-level driver module. The bottom-level driver module also has multiple mounting holes on its edge. The mounting holes are circular and are used to fix the bottom-level driver module.

[0031] Specifically, the underlying drive module is rectangular, measuring 120mm in length, 80mm in width, and 1.5mm in thickness. This rectangular shape facilitates installation and layout within the device, making full use of space, and also allows for easy connection and wiring with other modules.

[0032] The underlying driver module is made of epoxy resin glass cloth board. It has good electrical insulation properties, mechanical strength and heat resistance, which can meet the requirements of the circuit board in data transmission equipment and ensure the stability and reliability of the circuit.

[0033] The underlying driver module has multiple pads for connecting different components. These pads are evenly distributed on the underlying driver module, arranged according to a certain pattern and spacing. For example, corresponding pads are set at the positions corresponding to chip pins to achieve electrical connection between the chip and the circuit board; corresponding pads are also set at the positions where components such as capacitors and resistors need to be connected to ensure that the components can be accurately and reliably soldered onto the circuit board.

[0034] The bottom-level driver module has multiple circular mounting holes, each 3mm in diameter, along its edges. These holes are evenly distributed across the four edges of the module; for example, one hole is placed every 30mm along the long edge and every 20mm along the short edge. The location and number of mounting holes are designed according to the installation requirements of the device housing and the method of fixing the circuit board, ensuring that the bottom-level driver module can be securely installed in the designated position within the housing, preventing the circuit board from loosening or shifting due to vibration or other factors during device operation.

[0035] The RS232 interface of the positioning module connects to the corresponding interface on the underlying driver module via a data cable. The RS232 interface on the underlying driver module can be a serial port chip, such as the MAX232 chip. This serial port chip connects to pads on the circuit board, and then to the data cable, enabling data transmission with the positioning module. The data cable can be a shielded twisted pair cable with a core diameter of 0.5mm, a shielding layer thickness of 0.1mm, and an outer insulating sheath thickness of 0.8mm to reduce the impact of electromagnetic interference on data transmission.

[0036] The underlying driver module and the application layer module are electrically connected, which can be via ribbon cable or wire. For example, when using a ribbon cable, one end of the ribbon cable is connected to a specific interface on the underlying driver module through a connector. This interface can be a pin header socket with a pin pitch of 2.54mm. The other end of the ribbon cable is connected to the application layer module through a corresponding connector, enabling data interaction and signal transmission between the underlying driver module and the application layer module.

[0037] This embodiment of the invention uses a rectangular epoxy resin glass cloth board as the bottom drive module, which facilitates installation, adapts to standardized production, and provides good insulation, mechanical properties, and high-temperature resistance. The circular mounting holes on the edges facilitate fixing, ensuring module stability and contributing to the overall performance and reliability of the equipment.

[0038] In the above Figure 2 Based on the above, this embodiment of the invention also provides a structural schematic diagram of a data transmission device. (See diagram below.) Figure 3 As shown, a heat dissipation device is provided on the bottom driving module. The heat dissipation device includes a heat dissipation base plate and heat dissipation fins. The heat dissipation base plate is a rectangular metal plate of the same size as the bottom driving module and is made of aluminum alloy. It is tightly attached to the bottom driving module below the dense component area. The heat dissipation fins are multiple parallel long strip metal sheets of the same material as the heat dissipation base plate and are vertically fixed on the heat dissipation base plate.

[0039] In this embodiment of the utility model, the heat dissipation substrate of the heat dissipation device is a rectangular metal plate of the same size as the bottom driving module. The bottom driving module is 120mm long and 80mm wide, and the heat dissipation substrate is also a rectangle with a length of 120mm and a width of 80mm, and its thickness is 2mm.

[0040] The heat dissipation substrate is made of aluminum alloy, which has good thermal conductivity and can effectively conduct away the heat generated by the underlying driver module.

[0041] The heat dissipation substrate is tightly attached to the component-dense area of ​​the underlying driver module. In the area where power components (such as power chips and processing chips) are located, a tight fit is achieved using thermal grease. The thermal grease is 0.1mm thick and has excellent thermal conductivity, which can fill the tiny gaps between the heat dissipation substrate and the underlying driver module, ensuring effective heat transfer.

[0042] The heat dissipation fins are multiple parallel long strips of metal, and their material is the same as that of the heat dissipation substrate, which is aluminum alloy.

[0043] Each heatsink fin is 40mm long, 5mm wide, and 1mm thick, with a 3mm spacing between adjacent fins. They are vertically fixed to the heatsink base plate, forming a comb-like structure. This arrangement helps increase the heat dissipation area and promotes heat dissipation.

[0044] The heat dissipation fins are fixed to the heat dissipation base plate by welding. The welding is firm and reliable, ensuring that a good heat conduction path is formed between the heat dissipation fins and the heat dissipation base plate.

[0045] This embodiment of the invention utilizes an aluminum alloy heat dissipation substrate that is tightly bonded to the densely packed component area, enabling rapid heat absorption. Parallel-arranged heat dissipation fins increase the heat dissipation area, accelerating heat dissipation. Together, these two elements effectively reduce module temperature, ensuring stable operation of the underlying drive module and improving equipment reliability.

[0046] In some embodiments, the application layer module is encapsulated in a square box-shaped housing. The surface of the square box-shaped housing is provided with a plurality of heat dissipation holes. The heat dissipation holes are circular and evenly distributed on the four sides of the housing. The top of the square box-shaped housing is provided with a status indicator light. The indicator light is circular and is displayed through a circular lampshade. The circular lampshade is made of polycarbonate and is fixed to the top of the square box-shaped housing.

[0047] In this embodiment of the invention, the application layer module is encapsulated within a square box-shaped housing with sides of 60mm and a height of 40mm. This regular square design facilitates installation and fixation within the overall layout of the data transmission equipment, while also providing protection for internal components. The housing is made of fire-resistant plastic, such as flame-retardant plastic, with a wall thickness of 2mm. This ensures both sufficient mechanical strength and good insulation and flame-retardant properties, effectively preventing damage to internal components from external fire sources and ensuring safe operation of the equipment.

[0048] Multiple circular ventilation holes, each 5mm in diameter, are provided on the surface of the square box-shaped housing. To achieve good heat dissipation, the ventilation holes are evenly distributed on the four sides of the housing, arranged in a matrix along both the longitudinal and transverse directions. For example, there is a row every 15mm longitudinally and a hole every 10mm transversely. This ensures that the heat inside the housing can be dissipated in a timely manner, maintaining the application layer module within a suitable operating temperature range and preventing performance degradation or component damage due to overheating.

[0049] The top of the square, box-shaped casing features a circular status indicator light, 8mm in diameter. The indicator light uses high-brightness LEDs; different colored LEDs indicate different operating states of the application layer module, such as solid green for normal operation, flashing red for data transmission errors, and slow flashing yellow for standby. The indicator light is connected to the main control chip inside the application layer module via wires. The wire cores are 0.3mm in diameter and encased in a 0.5mm thick polyvinyl chloride (PVC) insulation layer to ensure stable and reliable signal transmission.

[0050] The indicator light is displayed through a circular lampshade made of polycarbonate, a material known for its high transparency and impact resistance. The lampshade is 1.5mm thick and is secured to the top of a square, box-shaped housing using clips or adhesive. If clips are used, four L-shaped clips, 5mm long and 3mm wide, are evenly spaced along the edge of the lampshade and fit snugly into pre-drilled slots on the top of the housing, ensuring a secure hold while facilitating disassembly and maintenance. If adhesive is used, a high-temperature resistant, insulating electronic adhesive is selected to ensure a tight seal between the lampshade and housing, preventing dust and moisture from affecting the indicator light's display.

[0051] This embodiment of the utility model features circular heat dissipation holes evenly distributed on the four sides of the application layer module encapsulation shell, which facilitates heat dissipation, ensures stable module operation, and prevents overheating damage. The top circular indicator light, paired with a polycarbonate lampshade, not only clearly displays the status but also serves a dual purpose of protection and indication due to its sturdy material and good light transmittance.

[0052] In some embodiments, the positioning module and the underlying driving module are connected via an RS232 data cable. One end of the RS232 data cable is a plug that matches the RS232 interface of the positioning module, and the other end is a socket that matches the corresponding interface on the circuit board of the underlying driving module. The core of the data cable is multi-strand tinned copper wire, and the core is wrapped with a shielding layer made of aluminum foil. The outermost layer of the core is an insulating sheath made of polyvinyl chloride.

[0053] In this embodiment of the invention, the plug that matches the RS232 interface of the positioning module is a standard 9-pin D-type plug. The plug body is made of high-strength engineering plastic, such as polybutylene terephthalate (PET), which has good wear resistance, heat resistance, and electrical insulation properties, ensuring that the plug will not be damaged by friction, high temperature, or electrical factors during long-term use. The nine pins of the plug are made of copper alloy and are gold-plated with a thickness of approximately 0.05 μm to improve the conductivity and corrosion resistance of the pins and ensure good contact with the RS232 interface of the positioning module.

[0054] The socket that matches the corresponding interface on the underlying driver module circuit board is also a 9-pin D-type socket, and its material and manufacturing process are compatible with the plug. The socket is firmly fixed to the circuit board of the underlying driver module by soldering, with full and uniform solder joints to ensure the stability of the electrical connection and the robustness of the mechanical connection. The internal pinhole of the socket uses a flexible metal sheet design to tightly clamp the pins of the plug, further improving the reliability of the contact.

[0055] The data cable's core consists of 16 strands of tin-plated copper wire, each strand with a diameter of 0.1mm. This multi-strand twisting design increases the wire's flexibility, facilitating internal wiring and improving the cable's tensile strength. Tin plating enhances the copper wire's oxidation resistance and conductivity, resulting in more stable data transmission.

[0056] The shielding layer wrapped around the wire core is made of aluminum foil, with a thickness of approximately 0.05mm. The aluminum foil is tightly wound around the wire core, effectively shielding it from external electromagnetic interference and preventing external electromagnetic signals from affecting data transmission. It also prevents signals transmitted inside the wire core from radiating outwards, thus avoiding interference with other equipment. To ensure shielding effectiveness, both ends of the aluminum foil are electrically connected to the metal casing of the plug and socket, forming a complete shielding loop.

[0057] The outermost layer of the wire core is an insulating sheath made of polyvinyl chloride (PVC). The insulating sheath is 1mm thick and possesses excellent insulation properties, abrasion resistance, and flexibility. The surface of the insulating sheath is smooth, free of bubbles, impurities, and other defects, ensuring that it will not be damaged by friction or external force during use, thus guaranteeing the safety and reliability of the cable.

[0058] The RS232 data cable has an overall outer diameter of approximately 5mm and a length of 300mm. This length satisfies the connection requirements between the positioning module and the underlying driver module without causing the cable to become tangled and messy inside the device, thus affecting the overall performance and aesthetics of the device.

[0059] This embodiment of the invention utilizes a multi-strand stranded tinned copper wire core in the RS232 data cable to enhance flexibility and conductivity, ensuring stable data transmission. The aluminum foil shielding layer effectively blocks external electromagnetic interference, improving signal quality. The PVC insulating sheath provides insulation and wear resistance, protecting the wire core, extending the data cable's lifespan, and ensuring reliable communication between the positioning and underlying driver modules.

[0060] In some embodiments, the underlying driver module communicates with the master station via an RS485 data cable. One end of the RS485 data cable is a plug that matches the RS485 interface on the circuit board of the underlying driver module, and the other end is a socket that matches the communication interface of the master station. The core of the data cable is a twisted pair of oxygen-free copper wire, and the core is wrapped with an insulation layer made of fluoroplastic. The outer shell of the plug and socket is sealed with a rubber sealing ring, which is an O-ring made of silicone rubber.

[0061] In this embodiment of the invention, the plug shell is made of high-strength, wear-resistant plastic material, such as nylon, which can withstand certain external impacts and protect the internal connection structure. The metal pins inside the plug are made of highly conductive copper alloy and are silver-plated with a thickness of approximately 0.1 μm to reduce contact resistance and improve the reliability of signal transmission. The arrangement and size of the pins conform to the RS485 interface standard to ensure precise mating with the RS485 interface on the underlying driver module circuit board.

[0062] The socket, compatible with the main station's communication interface, is made of durable materials and has the same specifications as the plug. The socket is securely mounted to the main station's communication equipment circuit board via soldering or crimping. The internal metal socket features a flexible design that tightly grips the plug's pins, ensuring a reliable electrical connection. The socket surface is also silver-plated to further enhance conductivity and corrosion resistance.

[0063] The data cable's core uses twisted-pair oxygen-free copper wire with a purity of over 99.99%, exhibiting extremely low resistance and excellent conductivity, effectively reducing signal loss during transmission. Each oxygen-free copper wire has a diameter of 0.5mm, and the two cores are twisted together with a twist pitch of 10mm. This twisted-pair structure helps suppress electromagnetic interference and improves the anti-interference capability of data transmission.

[0064] The insulation layer surrounding the conductor is made of fluoroplastics, such as polytetrafluoroethylene (PTFE). Fluoroplastics possess excellent electrical insulation properties, high-temperature resistance, and chemical stability, ensuring normal cable operation in various harsh environments. The insulation layer is 0.8 mm thick and evenly wraps around the conductor, providing reliable insulation protection. The smooth surface and low coefficient of friction of the fluoroplastic insulation layer facilitate cable routing within equipment and prevent damage from friction during bending.

[0065] The plug and socket housings are sealed with rubber O-rings made of silicone rubber. Silicone rubber possesses excellent elasticity, aging resistance, and sealing properties, effectively preventing dust, moisture, and other impurities from entering the plug and socket and affecting the electrical connection. The O-ring has a cross-sectional diameter of 2mm and is tightly embedded in the sealing groove of the plug and socket housing. When the plug is inserted into the socket, the O-ring is compressed, creating a good seal. In practical applications, a suitable amount of silicone grease can be applied to the surface of the O-ring to further improve sealing and waterproofing performance.

[0066] In this embodiment, the RS485 data cable connecting the underlying driver module to the master station uses twisted-pair oxygen-free copper wire cores, providing strong anti-interference capabilities and ensuring stable communication. The fluoroplastic insulation layer is high-temperature resistant and offers excellent insulation, adapting to complex environments. The rubber-sealed plug and socket are waterproof and dustproof, and the durable silicone rubber material effectively extends the data cable's lifespan.

[0067] In some embodiments, the housing of the data transmission device consists of an upper cover and a lower cover, both of which are rectangular flat plates. The upper cover and the lower cover are connected by a hinge made of stainless steel and are located on the long edge of one side of the housing of the data transmission device. The hinge allows the upper cover to rotate relative to the lower cover at an opening angle of 0-180 degrees. A sealing gasket is provided at the connection between the upper cover and the lower cover. The sealing gasket is a rectangular rubber gasket that is pasted on the corresponding edge of the upper cover and the lower cover.

[0068] In this embodiment of the invention, both the upper and lower covers are designed as rectangular flat plates to accommodate the layout of the internal modules of the data transmission device. The upper cover is 200mm long, 150mm wide, and 3mm thick; the lower cover has the same length and width as the upper cover, but is 4mm thick. This difference in thickness allows the lower cover to better support the weight of the internal modules, while the relatively thinner upper cover reduces the overall weight.

[0069] Both the upper and lower covers are made of high-strength engineering plastics, such as acrylonitrile-butadiene-styrene copolymer. This material has good mechanical properties, impact resistance and processability, and can effectively protect internal components such as positioning modules, bottom drive modules and application layer modules. At the same time, it is easy to manufacture and design. When the upper and lower covers are made of high-strength engineering plastics, the positioning antenna can be placed inside or outside the engineering plastics. This application does not impose any restrictions on this.

[0070] The hinge is made of stainless steel, ensuring excellent corrosion resistance and mechanical strength, and providing long-term stable support for the opening and closing of the cover. The hinge is located on one long edge of the data transmission device's housing. Its specific position can be in the middle of the long edge, or it can be offset towards one end depending on the device's internal structure and user habits. For example, if the main operating interface is on one side, the hinge can be placed on the opposite side for convenient operation.

[0071] The hinge is designed to allow the upper cover to rotate relative to the lower cover with an opening angle between 0 and 180 degrees. This wide opening angle facilitates operation inside the device, such as installation, maintenance, and module replacement. The hinge is secured to the corresponding positions on the upper and lower covers using screws or rivets. The screws or rivets are made of stainless steel with a diameter of 3mm to ensure a secure connection. The number of screws or rivets on each hinge depends on the hinge's length and the actual stress conditions, generally 3-5, evenly distributed across the hinge.

[0072] The sealing gasket is a rectangular rubber gasket made of silicone rubber. Silicone rubber has good elasticity, aging resistance, and sealing performance, effectively preventing dust, moisture, and other external impurities from entering the equipment and affecting its normal operation. The length and width of the sealing gasket match the edge dimensions of the connection between the upper and lower covers, and its thickness is 2mm. Its rectangular shape matches the edge shape of the upper and lower covers, ensuring complete coverage of the connection area.

[0073] The sealing gaskets are adhered to the corresponding edges of the upper and lower covers using a specialized high-temperature resistant and aging-resistant adhesive. Before adhesion, the edges of the upper and lower covers are cleaned to remove oil and impurities, enhancing adhesive adhesion. The adhesive is applied evenly, ensuring the sealing gaskets fit tightly against the edges of the upper and lower covers without air bubbles or gaps. After adhesion, a curing period is allowed to ensure a firm bond between the sealing gaskets and the upper and lower covers.

[0074] This embodiment of the invention features a housing consisting of a rectangular flat upper cover and a lower cover connected by stainless steel hinges, with an opening angle of 0-180 degrees for convenient internal inspection and maintenance. Rectangular rubber gaskets are affixed to the joints, effectively preventing dust and water damage and protecting internal components. The overall structure is robust and practical, extending the equipment's lifespan and ensuring stable operation.

[0075] In some embodiments, both the upper and lower covers are made of metal, and multiple ventilation holes are provided on both sides. The ventilation holes are elongated and evenly distributed in the middle area on both sides of the upper cover. Rainproof eaves are provided outside the ventilation holes, and dustproof nets are provided inside the ventilation holes. The dustproof nets are made of metal wire mesh and are fixed inside the ventilation holes by buckles. The buckles are made of plastic, L-shaped, and fixed to the edge of the ventilation holes.

[0076] In this embodiment of the invention, both the upper and lower covers are made of metal, such as aluminum alloy. Aluminum alloy has good strength, thermal conductivity, and corrosion resistance, which can provide reliable physical protection for the internal components of the device and also help the device to dissipate heat as a whole. When both the upper and lower covers are made of metal, the positioning antenna is placed on the outside of the metal material to avoid affecting the antenna's signal reception.

[0077] The ventilation holes on both sides of the top cover are elongated and have rainproof eaves to prevent rainwater from entering the equipment. Each ventilation hole is 30mm long and 5mm wide. This size ensures sufficient ventilation to effectively remove heat generated inside the equipment, while also preventing the ventilation holes from being too large and affecting the structural strength of the top cover.

[0078] Ventilation holes are evenly distributed in the central area on both sides of the top cover. In this application, a top cover measuring 200mm in length and 150mm in width can be provided. This application does not limit the size of the top cover; any top cover size that can realize the technical solution of this application is within the scope of the embodiments of this application. Along the length direction, a row of ventilation holes is provided every 40mm, with 3 ventilation holes in each row, arranged at equal intervals. This layout allows heat to be dissipated relatively evenly from various areas inside the device.

[0079] The dustproof mesh is made of metal wire mesh, such as stainless steel wire mesh. Stainless steel wire mesh has good corrosion resistance and mechanical strength, effectively blocking dust and other impurities from entering the equipment without excessively obstructing airflow. The mesh size is determined according to actual needs; for example, a mesh size of 1mm × 1mm can prevent dust from entering while ensuring ventilation.

[0080] The dustproof mesh is secured inside the ventilation holes with clips. The clips are made of plastic, such as L-shaped polypropylene plastic with a certain degree of toughness and strength. The clips are 8mm long, 5mm wide, and 2mm thick. A clip is placed every 10mm along the four edges of the ventilation holes. First, the wire mesh is cut to a size suitable for the ventilation holes. Then, one side of the clip is inserted into the pre-cut groove on the edge of the ventilation hole, and the other side firmly presses the wire mesh onto the ventilation hole, thus achieving a secure fixation of the dustproof mesh.

[0081] This embodiment of the application features elongated ventilation holes evenly distributed on both sides of the top cover in the middle, which facilitates heat dissipation. The metal wire mesh inside the ventilation holes effectively blocks dust. L-shaped plastic clips facilitate the fixing and removal of the dust mesh, making cleaning and maintenance convenient. This design balances heat dissipation and dust prevention, improving the stability and lifespan of the equipment.

[0082] In some embodiments, the housing of the data transmission device is further provided with a mounting bracket for fixing the device. The mounting bracket is L-shaped, with one end fixedly connected to the side of the housing by bolts made of stainless steel. The other end is provided with a mounting hole, which is circular. A shock-absorbing pad is provided at the end of the mounting bracket connected to the housing. The shock-absorbing pad is a rectangular rubber pad that is attached to the contact surface between the mounting bracket and the housing.

[0083] In this embodiment of the invention, the mounting bracket is L-shaped, a design that facilitates fixing the data transmission device on different mounting surfaces. The two sides of the L-shape are perpendicular to each other. The mounting bracket is made of high-strength metal, such as carbon steel, and undergoes surface galvanizing to enhance its corrosion resistance and adaptability to different working environments.

[0084] One end of the mounting bracket is bolted to the side of the data transmission equipment's housing. A matching 6mm diameter threaded hole is pre-drilled on the side of the housing to match the bolt. The bolt is made of stainless steel, such as 304 stainless steel, to ensure good corrosion resistance and mechanical strength. The bolt is 6mm in diameter and 20mm in length, ensuring it can pass through the mounting bracket and the side of the housing and be securely tightened. During installation, pass the bolt through the corresponding mounting hole on the mounting bracket, then screw it into the threaded hole on the side of the housing, and tighten it with a stainless steel nut to ensure a secure connection.

[0085] The other end of the mounting bracket has a circular mounting hole with a diameter of 8mm. This mounting hole is used to secure the data transmission device to an external mounting structure. The device can be securely installed in the designated location by using the matching screws or bolts passed through this mounting hole.

[0086] The vibration damping pads are rectangular rubber pads made of nitrile rubber, which has excellent vibration damping performance. They can effectively absorb vibrations generated during equipment operation and reduce the impact of vibrations on internal components. The length of the vibration damping pad is the same as the side length of the connection end between the mounting bracket and the housing, which is 80mm, the width is 30mm, and the thickness is 5mm.

[0087] This application embodiment utilizes an L-shaped mounting bracket for convenient equipment fixation, while the circular mounting holes accommodate various fixing methods. Stainless steel bolt connections provide a secure and rust-proof connection. Rectangular rubber shock-absorbing pads effectively buffer vibrations, reducing the risk of equipment damage due to vibration, ensuring stable operation of internal modules, extending equipment lifespan, and improving equipment reliability.

[0088] In some embodiments, the mounting bracket is made of aluminum alloy, and a reinforcing rib is provided at the L-shaped corner of the mounting bracket. The reinforcing rib is a triangular rib plate, made of the same material as the mounting bracket, and welded to the inside of the corner of the mounting bracket.

[0089] In this embodiment of the invention, the mounting bracket is made of aluminum alloy. Aluminum alloy has a good strength-to-weight ratio, ensuring that the mounting bracket can withstand the weight of the data transmission equipment and the stress that may occur during installation, while also being relatively lightweight, facilitating the installation and handling of the equipment. The surface of the aluminum alloy is anodized to form an oxide film with a thickness of approximately 10 μm.

[0090] A reinforcing rib, a triangular rib structure, is installed at the L-shaped corner of the mounting bracket. The base of the triangle is connected to the long side of the L-shaped bracket, with a length of 30mm; the height of the triangle is connected to the short side of the L-shaped bracket, with a length of 20mm; the thickness of the reinforcing rib is the same as that of the mounting bracket, 5mm. This triangular rib design effectively disperses the stress concentrated at the L-shaped corner, enhances the structural strength of the mounting bracket at this critical location, and prevents deformation or damage due to long-term stress.

[0091] The reinforcing rib is made of the same material as the mounting bracket. The reinforcing rib is fixed to the inside of the corner of the mounting bracket by welding. Argon arc welding is used, a method that ensures weld quality and creates a strong connection between the reinforcing rib and the mounting bracket.

[0092] This application embodiment utilizes a lightweight yet strong aluminum alloy mounting bracket that effectively supports the equipment. Triangular reinforcing ribs at the L-shaped corners enhance the structural strength of the bracket's corners, reduce stress concentration, lower the risk of bracket deformation, and make the equipment installation more stable, ensuring stable operation of the data transmission equipment in various environments.
