Description

Technical Field

[0001] This invention relates to the field of switch technology, specifically to a switch for a face recognition system with interface switching functionality. Background Technology

[0002] Driven by the wave of intelligentization, facial recognition systems have been widely used in various fields such as security monitoring, access control, and identity verification. The core of these systems lies in the collaboration between front-end facial recognition devices and back-end processing servers to achieve efficient identity recognition and data interaction. As a key network component connecting front-end acquisition devices and back-end systems, switches play a crucial role in data transmission, signal forwarding, and device networking, directly affecting the response speed and operational stability of facial recognition systems.

[0003] With the diversification of facial recognition applications, the interface types of front-end devices vary significantly across different scenarios. For example, indoor high-precision facial recognition cameras often use gigabit Ethernet interfaces to ensure real-time transmission of high-definition images, while outdoor explosion-proof facial recognition gates may be equipped with fiber optic interfaces to meet the needs of long-distance data transmission. Meanwhile, some older retrofitting scenarios still use acquisition devices with analog signal interfaces. At the same time, the interface specifications of the back-end processing system may also differ depending on the manufacturer and model, with common examples including 10 Gigabit Ethernet interfaces and USB 3.0 data interaction interfaces.

[0004] For example, Chinese utility model patent application number 202420972301.X discloses a switch that facilitates wiring, making it easier to classify and route the lines on the switch for subsequent line retrieval and maintenance. It also prevents the connecting lines on the switch from becoming loose or detached due to pulling, and the line distribution is simpler. However, this device still has certain shortcomings.

[0005] There is no cleaning mechanism on the dust filter. When the dust filter needs to be cleaned, it needs to be disassembled. The cleaning method that relies on manual disassembly does not meet the requirements of the facial recognition system for high reliability and low maintenance cost, and it is also difficult to adapt to the requirements of efficient operation and maintenance in large-scale deployment scenarios.

[0006] Therefore, we propose a switch for a face recognition system with interface switching capabilities to address the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a switch for a face recognition system with interface switching function, in order to solve the problem mentioned in the background art that the current market does not have a cleaning mechanism on the dust filter. When the dust filter needs to be cleaned, it needs to be disassembled. The cleaning method that relies on manual disassembly does not meet the requirements of face recognition system for high reliability and low maintenance cost, and is also difficult to adapt to the requirements of efficient operation and maintenance in large-scale deployment scenarios.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a switch for a face recognition system with interface switching function, comprising a switch body and a connection frame, wherein a network port and an optical port are installed on the front surface of the switch body, a storage slot is opened on the front surface of the switch body, and a photoelectric conversion module is installed on the storage slot, heat dissipation fins are installed on the upper surface of the switch body, and a heat dissipation vent is opened on the right side of the switch body.

[0009] A connecting frame is installed on the right side of the switch body, and a filter screen is provided on the right side of the connecting frame. Connecting blocks are installed on both the front and rear sides of the filter screen, and U-shaped grooves are opened on the connecting blocks. A vertical plate is installed above the connecting frame, and a second rotating mechanism is installed on the right side of the vertical plate. A cleaning brush assembly is installed on the second rotating mechanism.

[0010] Preferably, the photoelectric conversion module is slidably connected to the storage slot, and the photoelectric conversion module is electrically connected to the optical port.

[0011] With the above structural design, the photoelectric conversion module can slide along the storage slot. When it is necessary to switch interfaces, it can be slid out and electrically connected to the optical port to realize the conversion between optical signals and electrical signals. This adapts to the connection requirements of optical port and network port devices in the face recognition system without the need for additional external conversion equipment.

[0012] Preferably, the photoelectric conversion module is equipped with snap-fit ​​blocks on both the left and right sides, and the storage slot is equipped with abutment blocks on both the left and right sides. The snap-fit ​​blocks and the abutment blocks are slidably connected, and fastening bolts are installed on the abutment blocks.

[0013] With the above structural design, when storing the photoelectric conversion module, place the photoelectric conversion module in the storage slot, adjust it into place, and tighten the fastening bolts on the abutment block to fix the position of the photoelectric conversion module and prevent it from falling off.

[0014] Preferably, the heat dissipation fins are provided in multiple ways, and the heat dissipation fins are designed in a V-shape.

[0015] By adopting the above structural design, the multiple V-shaped heat dissipation fins on the switch body increase the contact area with the air, accelerate the dissipation of heat generated during switch operation, and avoid the stability of face recognition data transmission being affected by high temperature.

[0016] Preferably, a guide strip is installed on the right side of the connecting frame, and a sliding groove is provided on the left side of the filter screen, with the guide strip and the sliding groove being slidably connected.

[0017] With the above structural design, when installing the filter screen, the sliding groove on its left side slides along the guide strip on the right side of the connecting frame, which restricts the installation trajectory of the filter screen, ensures that the filter screen accurately covers the heat dissipation port, and facilitates subsequent disassembly or cleaning.

[0018] Preferably, a pusher is installed on the right side of the filter screen, and the surface of the pusher is provided with anti-slip texture.

[0019] With the above structural design, the push handle on the right side of the guide bar makes it easy for the operator to push the filter screen along the guide bar. The anti-slip texture on the surface increases the friction of the hand and avoids slipping when pushing. When it is necessary to clean the filter screen, the push handle is used to pull the filter screen back and forth, and the cleaning brush assembly is used for cleaning.

[0020] Preferably, a first rotating mechanism is installed on both the front and rear sides of the connecting frame, and a rotating block is installed on each of the first rotating mechanisms. A threaded rod is installed on the rotating block, and a limit nut is installed on the threaded rod. When the threaded rod is rotated under force, it engages with the U-shaped groove on the connecting block.

[0021] With the above structural design, when fixing the filter screen, the rotating block is rotated by the first rotating mechanism, so that the threaded rod is engaged in the U-shaped groove of the connecting block, and then the limit nut is tightened to fix the threaded rod, thereby firmly installing the filter screen on the connecting frame.

[0022] Preferably, a fixing frame is installed on the right side of the vertical plate, and an arc-shaped block is installed inside the fixing frame by means of a telescopic spring.

[0023] With the above structural design, the telescopic spring provides elastic support for the arc-shaped block in the fixed frame on the right side of the vertical plate. When the cleaning brush assembly is rotated and stored, the arc-shaped block can fit against the surface of the cleaning brush assembly, which can limit the cleaning brush assembly. At the same time, the guide rod ensures that the arc-shaped block moves stably.

[0024] Preferably, a guide rod is installed on the right side of the arc-shaped block, and the guide rod passes through the fixed frame and is slidably connected to the fixed frame.

[0025] With the above structural design, the guide rod on the right side of the arc-shaped block passes through the fixed frame. When the arc-shaped block is squeezed by the cleaning brush assembly or the telescopic spring rebounds, the guide rod slides along the fixed frame, restricting the movement direction of the arc-shaped block and preventing it from deviating.

[0026] Preferably, the cleaning brush assembly has a limiting groove and a limiting bolt is installed on the vertical plate. When the cleaning brush assembly is cleaning in a vertical state, the center line of the limiting groove coincides with the center line of the limiting bolt.

[0027] With the above structural design, when cleaning the filter screen, the cleaning brush assembly is rotated to a vertical position through the second rotating mechanism, so that the limiting groove on the cleaning brush assembly is aligned with the limiting bolt on the vertical plate. The limiting bolt is tightened to fix the cleaning brush assembly, ensuring that the brush body is in a stable position during cleaning and improving the cleaning effect.

[0028] Compared with the prior art, the beneficial effects of the present invention are: the switch for the face recognition system with interface switching function:

[0029] 1. Flexible interface switching to adapt to multiple device types.

[0030] The photoelectric conversion module, which can slide inside the storage slot, can quickly switch between optical and electrical signals, adapting to network and optical port devices in the face recognition system without the need for additional external conversion equipment. The fixing structure of the snap-fit ​​block, abutment block, and fastening bolts ensures the stability of the photoelectric conversion module when stored, meeting the device connection requirements in different scenarios.

[0031] 2. Efficient heat dissipation ensures stable data transmission.

[0032] Multiple V-shaped heat dissipation fins on the switch body increase the heat dissipation area and accelerate heat dissipation. At the same time, the heat dissipation vents assist air circulation, preventing the switch body from slacking or malfunctioning due to high temperature, and ensuring the real-time and stable transmission of key information such as high-definition facial recognition images and identity verification data.

[0033] 3. Easy-to-clean filter reduces maintenance costs.

[0034] The filter screen on the connecting frame can be quickly installed and removed via guide strips and slides, and the cleaning brush assembly can be driven to clean without disassembly via the second rotating mechanism; during cleaning, the brush body position is fixed by limit bolts, and the filter screen is moved with the pusher to achieve efficient dust removal, which is convenient for disassembling and cleaning the filter screen, solving the cumbersome problem of traditional filter screens relying on manual disassembly and cleaning, and adapting to the operation and maintenance needs of large-scale deployment;

[0035] 4. Sturdy structure, improving equipment reliability

[0036] The filter screen is fixed to the threaded rod and the limiting nut through the U-shaped groove of the connecting block, making it firmly installed and not easy to loosen; the telescopic spring in the fixed frame cooperates with the arc-shaped block to limit the cleaning brush assembly, preventing the parts from shifting during transportation or use. The overall structural design improves the reliability of the switch in the long-term operation of the face recognition system. Attached Figure Description

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figures 1-11This invention provides a technical solution: a switch for a face recognition system with interface switching function, comprising a switch body 1, a network port 2, an optical port 3, a storage slot 4, a photoelectric conversion module 5, a snap-fit ​​block 6, a contact block 7, fastening bolts 8, heat dissipation fins 9, heat dissipation vents 10, a connecting frame 11, a guide strip 12, a filter screen 13, a sliding groove 14, a push handle 15, a connecting block 16, a U-shaped groove 17, a first rotating mechanism 18, a rotating block 19, a threaded rod 20, a limit nut 21, and a vertical plate 22. The switch body 1 includes a fixed frame 23, a telescopic spring 24, an arc-shaped block 25, a guide rod 26, a second rotating mechanism 27, a cleaning brush assembly 28, a limiting groove 29, and a limiting bolt 30. A network port 2 and an optical port 3 are mounted on the front surface of the switch body 1. A storage groove 4 is formed on the front surface of the switch body 1, and a photoelectric conversion module 5 is installed on the storage groove 4. The photoelectric conversion module 5 is slidably connected to the storage groove 4 and electrically connected to the optical port 3. The photoelectric conversion module 5 can slide along the storage groove 4. (The last sentence appears to be incomplete and possibly refers to a different component: "Need to switch interfaces...") When the optical conversion module 5 is slid out and electrically connected to the optical port 3, it realizes the conversion between optical signals and electrical signals, adapting to the connection requirements of the optical port 3 and the network port 2 in the face recognition system. No additional external conversion equipment is required. The left and right sides of the optical conversion module 5 are equipped with snap-fit ​​blocks 6, and the left and right sides of the storage slot 4 are equipped with abutment blocks 7. The snap-fit ​​blocks 6 and abutment blocks 7 are slidably connected. Each abutment block 7 is equipped with a fastening bolt 8. When storing the optical conversion module 5, place the optical conversion module 5 in the storage slot 4, adjust it into place, and tighten the fastening bolt 8 on the abutment block 7 to fix the position of the optical conversion module 5 and prevent the optical conversion module 5 from falling off. The upper surface of the switch body 1 is equipped with heat dissipation fins 9. There are multiple heat dissipation fins 9, and the heat dissipation fins 9 are designed in a V-shape. The multiple V-shaped heat dissipation fins 9 on the switch body 1 increase the contact area with the air, accelerate the dissipation of heat generated during the operation of the switch, and avoid the stability of face recognition data transmission due to high temperature. The right side of the switch body 1 is provided with a heat dissipation vent 10.

[0051] A connection frame 11 is installed on the right side of the switch body 1, and a filter 13 is installed on the right side of the connection frame 11. A guide strip 12 is installed on the right side of the connection frame 11, and a sliding groove 14 is opened on the left side of the filter 13. The guide strip 12 is slidably connected to the sliding groove 14. When installing the filter 13, the sliding groove 14 on its left side slides along the guide strip 12 on the right side of the connection frame 11, restricting the installation trajectory of the filter 13 and ensuring that the filter 13 accurately covers the heat dissipation vent 10. At the same time, it is convenient for subsequent disassembly or cleaning. A pusher 15 is installed on the right side of the filter 13, and the surface of the pusher 15 is provided with anti-slip texture. The pusher 15 on the right side of the guide strip 12 makes it convenient for the operator to push the filter 13 to slide along the guide strip 12. The anti-slip texture on the surface increases the friction of the hand and avoids slipping when pushing. When the filter screen 13 needs to be cleaned, the filter screen 13 is moved back and forth by the push handle 15, and cleaning is performed under the action of the cleaning brush assembly 28. Connecting blocks 16 are installed on both the front and rear sides of the filter screen 13, and each connecting block 16 has a U-shaped groove 17. First rotating mechanisms 18 are installed on both the front and rear sides of the connecting frame 11, and rotating blocks 19 are installed on each of the first rotating mechanisms 18. Threaded rods 20 are installed on the rotating blocks 19, and limit nuts 21 are installed on the threaded rods 20. When the threaded rods 20 are rotated under force, they engage with the U-shaped grooves 17 on the connecting blocks 16. When fixing the filter screen 13, the rotating blocks 19 are rotated by the first rotating mechanism 18, so that the threaded rods 20 engage with the U-shaped grooves 17 on the connecting blocks 16, and then the limit nuts 21 are tightened to fix the threaded rods. 20, thereby securely installing the filter screen 13 onto the connecting frame 11. A vertical plate 22 is installed above the connecting frame 11, and a fixing frame 23 is installed on the right side of the vertical plate 22. An arc-shaped block 25 is installed inside the fixing frame 23 via a telescopic spring 24. Inside the fixing frame 23 on the right side of the vertical plate 22, the telescopic spring 24 provides elastic support for the arc-shaped block 25. When the cleaning brush assembly 28 rotates and retracts, the arc-shaped block 25 can fit against the surface of the cleaning brush assembly 28, thus limiting the movement of the cleaning brush assembly 28. At the same time, the guide rod 26 ensures the stable movement of the arc-shaped block 25. A guide rod 26 is installed on the right side of the arc-shaped block 25, and the guide rod 26 passes through the fixing frame 23. The guide rod 26 is slidably connected to the fixing frame 23. The fixed frame 23 is used to guide the arc-shaped block 25 to slide along the fixed frame 23 when the arc-shaped block 25 is squeezed by the cleaning brush assembly 28 or when the telescopic spring 24 rebounds, thus limiting the movement direction of the arc-shaped block 25 and preventing deviation. A second rotating mechanism 27 is installed on the right side of the vertical plate 22, and the cleaning brush assembly 28 is mounted on the second rotating mechanism 27. The cleaning brush assembly 28 has a limiting groove 29, and a limiting bolt 30 is installed on the vertical plate 22. When the cleaning brush assembly 28 is in a vertical position for cleaning, the center line of the limiting groove 29 coincides with the center line of the limiting bolt 30. When cleaning the filter screen 13, the cleaning brush assembly 28 is rotated to a vertical position via the second rotating mechanism 27, aligning the limiting groove 29 on the cleaning brush assembly 28 with the limiting bolt 30 on the vertical plate 22.Tighten the limiting bolt 30 to secure the cleaning brush assembly 28, ensuring the brush body remains stable during cleaning and improving cleaning effectiveness.

[0052] Working principle: When using this face recognition system switch with interface switching function, firstly, the switch body 1 serves as the core carrier. Its front surface network port 2 can be directly connected to indoor face cameras and other electrical signal devices, while the optical port 3 is adapted to outdoor fiber optic interface devices. When it is necessary to switch the interface type, loosen the fastening bolt 8, and slide the photoelectric conversion module 5 in the storage slot 4 out along the sliding fit between the snap block 6 and the abutment block 7, so that it is electrically connected to the optical port 3, realizing the conversion between optical signals and electrical signals.

[0053] When the switch body 1 is running, the multiple V-shaped heat dissipation fins 9 on the upper surface increase the heat dissipation area, which, together with the heat dissipation vent 10 on the right side, accelerates heat dissipation and avoids high temperature affecting data transmission. On the connecting frame 11 outside the heat dissipation vent 10, the filter screen 13 is slidably installed on the guide strip 12 on the right side of the connecting frame 11 through the left sliding groove 14, accurately covering the heat dissipation vent 10 to filter dust. After installation, the rotating block 19 is rotated by the first rotating mechanism 18 on the front and rear sides of the connecting frame 11, so that the threaded rod 20 is engaged in the U-shaped groove 17 of the filter screen 13 connecting block 16, and the limit nut 21 is tightened to fix the filter screen 13.

[0054] When the filter screen 13 needs cleaning, rotate the cleaning brush assembly 28 on the second rotating mechanism 27 on the right side of the vertical plate 22 to a vertical position, aligning the limiting groove 29 of the cleaning brush assembly 28 with the limiting bolt 30 of the vertical plate 22. Tighten the limiting bolt 30 to fix the brush body, loosen the limiting nut 21, and rotate the threaded rod 20 to disengage it from the U-shaped groove 17. The filter screen 13 is then pushed along the guide strip 12 by the anti-slip pusher 15 on the right side of the filter screen 13. Simultaneously, during the movement of the filter screen 13, the cleaning brush assembly 28 removes dust from the filter screen surface. When the cleaning brush assembly 28 is to be stored, rotate the cleaning brush assembly 28. Under the action of the rebound force, the telescopic spring 24 in the fixing frame 23 on the right side of the vertical plate 22 pushes the arc block 25 to fit against the brush body for limiting. The guide rod 26 on the right side of the arc block 25 slides along the fixing frame 23 to ensure the stable movement of the arc block 25, thus completing a series of operations. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
