[0021] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The specific embodiments of this application are described in detail below, but it should be understood that the scope of protection of this invention is not limited to the specific embodiments.

[0023] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0024] like Figure 1 and Figure 2 As shown, an intelligent monitoring terminal for a 5G communication base station provided in this application embodiment includes a housing 1; an opening 12 disposed inside the housing 1; a multi-degree-of-freedom adjustment mechanism disposed inside the opening 12; and a monitoring component 2 installed on the multi-degree-of-freedom adjustment mechanism, the monitoring component 2 including at least one camera; wherein, the multi-degree-of-freedom adjustment mechanism is configured to drive the monitoring component 2 to perform at least two degrees of freedom orientation adjustment to change the monitoring angle of the monitoring component 2.

[0025] The outer shell serves as the main support and protective structure of the intelligent monitoring terminal. Inside, there is a specially designed open cavity that provides installation space and movement range for the multi-degree-of-freedom adjustment mechanism.

[0026] A multi-degree-of-freedom adjustment mechanism is the core moving component, which is usually composed of a set of rigid rods connected by a revolute joint. For example, it may include a first-stage hinge rod for pitch adjustment and one or more second-stage swing rods for horizontal azimuth adjustment.

[0027] The monitoring component can be fixed to the end effector of the multi-degree-of-freedom adjustment mechanism, such as the free end of the swing arm. By controlling the relative rotation of the hinges at each stage through a drive mechanism, such as a motor, the end camera can continuously change its spatial orientation in at least two independent rotational dimensions, such as pitch and azimuth, thereby achieving flexible and precise adjustment of the monitoring perspective.

[0028] like Figure 3As shown, in one optional embodiment, the multi-degree-of-freedom adjustment mechanism may include a bracket 13 fixedly connected within the opening 12; a hinge rod 14 hinged to the bracket 13; and a mounting plate 16 fixedly connected to the end of the hinge rod 14; wherein the hinge rod 14 and the bracket 13 form a first rotary joint to drive the mounting plate 16 to adjust the pitch direction around a horizontal axis. A first motor 15 is mounted on the hinge rod 14, and the output end of the first motor 15 is drively connected to the hinge rod 14 to drive the hinge rod 14 to rotate around the rotation axis of the first rotary joint; and at least one of an angle limiting structure and a self-locking structure is provided between the hinge rod 14 and the bracket 13; wherein the angle limiting structure is used to limit the rotation angle range of the hinge rod 14, and the self-locking structure is used to maintain the posture of the hinge rod 14 after the drive is released. Secondly, the multi-degree-of-freedom adjustment mechanism may also include at least one swing rod 18; a hinge seat 17 is provided on the mounting plate 16, and at least one swing rod 18 is hinged to the hinge seat 17 to form a second rotating pair, so as to realize that the monitoring component 2 rotates relative to the mounting plate 16 about the rotation axis of the second rotating pair; wherein, the rotation axis of the second rotating pair intersects with the rotation axis of the first rotating pair; the monitoring component 2 is installed at the free end of the swing rod 18.

[0029] In this embodiment, the multi-degree-of-freedom adjustment mechanism can adopt a modular, hierarchical rotation structure design. Specifically, the multi-degree-of-freedom adjustment mechanism may include a primary pitch adjustment module and a secondary azimuth adjustment module.

[0030] The first-stage pitch adjustment module consists of a bracket 13 fixedly connected within the opening 12, a hinge rod 14 hinged to the bracket 13 via a bearing or shaft, and a mounting plate 16 fixedly connected to the distal end (i.e., the non-hinged end) of the hinge rod 14. The hinge point between the hinge rod 14 and the bracket 13 forms a first revolute joint, whose axis of rotation is typically designed to be horizontal. To drive this rotation, a first motor 15 is mounted on the hinge rod 14. The output shaft of the first motor 15 is connected to the hinge rod 14 via a coupling, reducer, or other transmission components, thereby outputting torque to drive the hinge rod 14 to perform precise rotational motion around the axis of the first revolute joint.

[0031] As an optimization method, an angle limiting structure (such as a mechanical stop or limit switch) and / or a self-locking structure (such as a worm gear mechanism, a motor with a brake, or a friction plate) can be integrated at the hinge point between the hinge rod 14 and the bracket 13. The angle limiting structure is used to mechanically limit the rotation angle range of the hinge rod 14 to prevent damage to internal cables or structures due to excessive movement; the self-locking structure can automatically maintain the current pitch attitude of the hinge rod 14 and its mounting plate 16 by relying on mechanical friction or the self-locking principle when the first motor 15 is de-energized or stops driving, thus avoiding angle deviation due to gravity or vibration.

[0032] Secondly, the secondary orientation adjustment module can be mounted on the mounting plate 16. A hinge seat 17 is fixedly mounted on the mounting plate 16, and at least one swing rod 18 is hinged to this hinge seat 17 via another shaft or bearing, forming a second rotary joint. The rotation axis of this second rotary joint (for example, it can be designed to be perpendicular to the plane of the mounting plate 16, i.e., approximately vertical) intersects spatially with the horizontal axis of the aforementioned first rotary joint. This orthogonal or oblique axial relationship is the basis for achieving two independent degrees of freedom adjustment. Finally, the monitoring component 2 is securely mounted on the free end of the swing rod 18.

[0033] like Figure 4 As shown, in one optional embodiment, a driven gear 5 is fixedly connected to the swing arm 18; the driven gear 5 meshes with the drive gear 51, and the drive gear 51 is connected to the output end of the third motor 52; the third motor 52 is configured to drive the drive gear 51 to rotate, thereby driving the driven gear 5 to rotate, and driving the swing arm 18 to swing synchronously around the second rotating pair.

[0034] To further enhance adjustment flexibility or as a backup drive method, in some embodiments, a wedge block 53 with an inclined guide slope can be fixedly connected to one side of the swing rod 18. The adjusting push rod 55 is configured to slide along the inclined surface of the wedge block 53 and is connected to a telescopic rod 54. When the swing rod 18 needs to be driven to swing, the telescopic rod 54 can be controlled to extend or retract. The linear motion of the telescopic rod 54 pushes or pulls the adjusting push rod 55, causing it to slide on the inclined surface of the wedge block 53. Due to the effect of the inclined surface, the linear motion of the adjusting push rod 55 can be decomposed into a pushing or pulling force perpendicular to the inclined surface on the wedge block 53 (i.e., on the swing rod 18). This force generates a torque, driving the swing rod 18 to swing synchronously outward or inward about the axis of the second revolute joint. This method is suitable for situations where two symmetrically arranged swing rods 18 need to produce synchronous but directionally adjustable opposite or opposite movements.

[0035] In one alternative embodiment, a retaining ring 45 may be fixedly connected to one end of the swing arm 18, and the retaining ring 45 is connected to a tension spring 46; the tension spring 46 is used to apply a restoring force to the swing arm 18, so that the swing arm 18 automatically returns to the preset midpoint angle or preset range after the drive is released.

[0036] The preset center angle refers to a reference angle position or a reference angle range pre-set for the swing arm 18. The reference position usually refers to a default center position of the swing arm 18 in the rotation stroke of the second rotary joint when it is in a balanced state without external driving force. For example, the position where the swing arm 18 is perpendicular to the mounting plate 16 (i.e., 0-degree deflection angle) is defined as the center position.

[0037] The reference range can refer to a small allowable angle interval (such as ±5 degrees), within which the system considers the swing arm to be in the neutral position.

[0038] During operation, the central processing unit controls the first motor 15 to drive the hinge rod 14 to rotate around the horizontal axis, thereby causing the entire mounting plate 16 and all components mounted on it (including the swing rod 18 and the camera) to adjust their pitch angle synchronously. Simultaneously, the swing rod 18 can be controlled to swing horizontally around the vertical axis of the hinge base 17 via a drive mechanism (such as gears or a motor), thus independently changing the horizontal azimuth angle of the camera. This two-stage motion combination achieves precise and flexible positioning of the monitoring components in both pitch and horizontal dimensions.

[0039] In one alternative implementation, such as Figure 5 As shown, the monitoring component 2 includes an image camera 20 and an infrared camera 21. The image camera 20 and the infrared camera 21 can be respectively mounted on the end of at least one swing arm 18, that is, they adopt a separate independent installation mode. For example, suppose the multi-degree-of-freedom adjustment mechanism includes two swing arms 18, and the two swing arms 18 are respectively hinged to both ends of the mounting plate 16; wherein, the image camera 20 is mounted on the end of one swing arm 18, and the infrared camera 21 is mounted on the end of the other swing arm 18. In this way, each camera can adjust its own horizontal azimuth angle through the independent movement of its respective swing arm 18, while both share the pitch angle adjustment driven by the hinge rod 14.

[0040] Alternatively, the image camera 20 and the infrared camera 21 can be mounted at different positions on the same swing arm 18, i.e., an integrated coaxial mounting mode can be adopted. For example, the mounting interfaces of the two cameras can be arranged side by side or stacked one on top of the other on a common camera bracket, so that the optical axes of the two cameras are as parallel as possible or converge at a fixed small angle. The integrated unit, as a whole, is oriented by the single swing arm 18 to which it is attached.

[0041] Using the above method, in the separate independent installation mode, the two cameras can point in different directions, thus doubling the monitoring range or allowing simultaneous attention to two key areas; they can also be adjusted to be approximately in the same direction, providing heterogeneous image data for the same scene, facilitating pixel-level or feature-level deep data fusion and improving the accuracy of target detection and recognition. Secondly, in the integrated coaxial installation mode, the two cameras have highly consistent perspectives, and the acquired heterogeneous images correspond almost completely in space, greatly simplifying the algorithmic complexity of subsequent image registration and fusion, and facilitating rapid and accurate multispectral analysis.

[0042] In one alternative implementation, such as Figure 6 As shown, a control box 11 can be fixedly mounted on one side of the outer casing 1. Wherein, as... Figure 7 The diagram shown is a schematic representation of the internal structure of a housing 11 provided in an embodiment of this application. Figure 6 As can be seen, a central processing unit 3 is fixedly installed inside the control box 11. The central processing unit 3 is electrically connected to the monitoring component 2 and is configured to identify abnormal events from the monitoring data output by the monitoring component 2.

[0043] The central processing unit 3 is electrically connected to the power supply module 31, the storage module 32, the alarm module 33, and the communication module 34. The central processing unit 3 is configured to compare the real-time monitoring images collected by the monitoring component 2 with the historical monitoring data in the storage module 32 to identify abnormal events; and to associate the comparison results with the real-time monitoring images and store them in the storage module 32.

[0044] Secondly, the central processing unit 3 is also electrically connected to the conversion module 4 and the drive module 43; the conversion module 4 is electrically connected to the transmission module 41 and the imaging module 42; the drive module 43 is electrically connected to the detection module 44; the detection module 44 is configured to detect the angular position of the multi-degree-of-freedom adjustment mechanism and output an angle signal, and the central processing unit 3 controls the multi-degree-of-freedom adjustment mechanism to perform closed-loop adjustment based on the angle signal. The communication module 34 includes a network module 35, a 5G module 36, an optical fiber module 37, and a transceiver module 38; the network module 35, 5G module 36, and optical fiber module 37 are electrically connected to the transceiver module 38.

[0045] During operation, the raw video stream acquired by monitoring component 2 is first sent to shooting module 42 for initial control and access, and then enters conversion module 4 (including ADC, ISP, etc.) to complete preprocessing such as format standardization, noise reduction and compression. The processed structured data is uploaded to central processing unit 3 via the high-speed interface of transmission module 41.

[0046] Within the central processing unit 3, the intelligent analysis process unfolds in parallel: on one hand, real-time data can be temporarily stored in storage module 32 (such as eMMC or SSD); on the other hand, the central processing unit 3 can call the pre-built historical monitoring big data model (including normal scene features and abnormal samples) in storage module 32, and perform deep feature comparison and pattern matching with the real-time image by running algorithms such as image recognition, temperature difference and behavior detection. When the calculated scene deviation exceeds the preset threshold (such as the appearance of unknown objects, abnormal temperature zones or specific behaviors), it is judged as an abnormal event. Once an anomaly is identified, the central processing unit 3 immediately triggers the alarm module 33 to start on-site and remote alarms. At the same time, the generated comparison results (anomaly type, confidence level, etc.) are spatiotemporally correlated with the real-time image (keyframe or segment) that triggered the alarm to form a traceable complete log package and store it back to storage module 32. This process continuously iterates and optimizes the historical database and recognition model, giving the system self-learning and adaptive capabilities.

[0047] Optionally, to ensure the accuracy and stability of the monitoring perspective, the detection module 44 (such as an angle sensor or encoder) can sense the angular position of the multi-degree-of-freedom adjustment mechanism in real time and feed back the angle signal to the central processing unit 3. The central processing unit 3 compares the actual angle with the target angle (from a preset position or tracking algorithm), calculates the control quantity, and then precisely drives the actuators such as the first motor 15, the third motor 52, or the telescopic rod 54 through the drive module 43 (such as a motor drive circuit), thereby completing a high-precision closed-loop adjustment of perception, decision-making, and execution.

[0048] Optionally, to achieve reliable data interaction, a redundant and efficient communication network can be equipped. The central processing unit 3 can connect to the outside world through the communication module 34, which integrates multiple access methods such as network module 35 (Ethernet), 5G module 36 (cellular communication), and fiber optic module 37 (optical communication). These modules are all connected to the transceiver module 38 for baseband and signal conversion, and finally transmit and receive signals through antenna 26 or fiber optic interface. In practical applications, the optimal communication link can be automatically or manually selected according to environmental, bandwidth, and reliability requirements to ensure real-time and stable transmission of monitoring data, alarm information, and control commands.

[0049] To achieve reliable protection and convenient deployment and retraction of antenna 26, in one optional implementation, such as Figure 8 As shown, a foldable antenna mechanism is integrated on the outside of the control box 11. Specifically, a protective plate 22 is fixedly connected to one outer wall of the control box 11. The protective plate 22 can be made of metal or high-strength engineering plastic, and its interior is designed with an inwardly recessed protective groove 23, the shape and size of which match the antenna in its retracted state.

[0050] On the inner side of the protective plate 22 (i.e., the side closest to the control box 11), a connecting seat 24 is fixedly connected. A mounting rod 25 is hinged to the connecting seat 24 via a pivot or hinge, allowing the mounting rod 25 to rotate around the hinge axis within a certain angle range (typically greater than 90 degrees). At one end (the extended end) of the mounting rod 25, an antenna 26 is fixedly mounted, which integrates a transceiver module 38 for transmitting and receiving wireless signals. At the other end of the mounting rod 25 (the end closest to the hinge point), a second motor 27 is mounted. This second motor 27 is preferably a small servo motor or servo motor, its housing fixed to the connecting seat 24 or the protective plate 22, and its output shaft is drively connected to the mounting rod 25 (e.g., by directly driving the hinge axis or through a gear pair). The second motor 27 is configured to output torque to drive the mounting rod 25 to rotate around the hinge axis when it receives a control command from the central processing unit 3.

[0051] Under normal operating conditions, the second motor 27 drives the mounting rod 25 to flip outwards, allowing the antenna 26 to fully extend beyond the protective slot 23 into its unfolded working posture, ensuring optimal signal transmission and reception performance. When the monitoring terminal needs to be powered off for an extended period, undergo maintenance, or when the system determines that it is in extreme weather conditions (such as blizzards or hail), the central processing unit 3 can control the second motor 27 to reverse, driving the mounting rod 25 to flip towards the protective plate 22, ultimately retracting the antenna 26 completely into the protective slot 23, achieving a folded storage and protective posture. The sidewalls of the protective slot 23 provide circumferential physical protection for the antenna.

[0052] In this embodiment, by storing the antenna within a robust protective slot, firstly, physical damage caused by accidental impacts, severe weather, or animal activity can be effectively avoided, significantly improving the reliability of key communication components, extending equipment lifespan, and reducing maintenance costs. Secondly, this design greatly enhances the environmental adaptability and deployment flexibility of the monitoring terminal, enabling it to intelligently cope with severe weather and present a neat shape after storage, facilitating transportation and installation in space-constrained environments. Furthermore, the antenna deployment and retraction status can be automatically controlled by the central processing unit based on policies, instructions, or sensor data, achieving intelligent and convenient management, particularly suited to the application requirements of unattended base stations. Finally, while ensuring antenna safety, this design does not sacrifice system connectivity—during antenna storage, the terminal can still maintain communication via wired connections such as fiber optics, thus maintaining the integrity and availability of the monitoring data link in extreme situations. Overall, this design upgrades simple physical protection into a comprehensive solution integrating reliability enhancement, environmental adaptability, intelligent control, and communication assurance.

[0053] Furthermore, to dynamically enhance antenna signal transmission and reception performance while maintaining a compact structure, in one optional implementation, an adjustable conical reflector mechanism can be integrated into the antenna mounting rod 25. Specifically, as... Figure 9 and Figure 10 As shown, multiple axially extending grooves 6 are provided on the side of the mounting rod 25. An adjusting rod 61 is hinged to each groove 6 via a pivot. The multiple adjusting rods 61 are evenly distributed along the circumference of the mounting rod 25 and the antenna 26, forming a skeleton structure surrounding the antenna.

[0054] Among them, circumferential direction refers to the distribution around the central axis of a cylinder or rod in the circumferential direction.

[0055] A conical reflector 62 is fixedly connected (e.g., glued or snapped) to the outer surface of each adjusting rod 61. This conical reflector 62 can be made of flexible, foldable fabric or film material, with its inner surface coated with a metallic reflective coating (such as an aluminum coating) to form an electromagnetic wave reflecting surface. The reflector sections on all adjusting rods 61 are joined together to form a complete conical reflective surface surrounding the antenna 26.

[0056] To achieve stable positioning and controllable adjustment of the frame structure, the surface of the mounting rod 25 is also provided with a fixing groove 63, in which a clamping spring 64 is installed. One end of the spring is clamped against the side of the adjusting rod 61, providing it with an elastic positioning force pointing in the unfolding direction, so that it has an unfolding tendency when there is no external force constraint.

[0057] The core drive adjustment mechanism may include an adjusting telescopic rod 65 (such as a miniature electric actuator), whose cylinder is fixedly mounted on one side of the mounting rod 25. A collar 66 is fixedly mounted at the piston rod end of the adjusting telescopic rod 65. This collar 66 simultaneously slides on the outer surface of all adjusting rods 61.

[0058] When signal enhancement is needed, the control adjustment rod 65 extends, pushing the collar 66 to slide towards the far end (i.e., the antenna end) of the mounting rod 25. The collar 66 releases the constraint on the base of the adjustment rod 61, which unfolds outward under the push of the tension spring 64, thus expanding the flexible conical reflector 62 to form an effective signal reflection and focusing surface. When retraction is needed, the control adjustment rod 65 retracts, pulling the collar 66 towards the near end (hinged end) of the mounting rod 25. The collar 66 compresses all the adjustment rods 61, causing them to overcome the elastic force of the tension spring 64 and retract towards the axis of the mounting rod 25, thereby flexibly folding the conical reflector 62 tightly against the mounting rod 25, achieving minimal volume storage.

[0059] The working principle of this intelligent monitoring terminal is as follows: The control swing arm 18 rotates left and right around the hinge seat 17 to adjust the angle, thereby driving the image camera 20 and infrared camera 21 to rotate and align in multiple directions, expanding the monitoring range; the image camera 20 and infrared camera 21 perform monitoring and shooting, and are integrated and controlled with the shooting module 42 to form shooting data; the transmission module 41 receives the shooting data, converts the data format through the conversion module 4, and transmits it to the central processing unit 3; the central processing unit 3 is connected to the storage module 32 to store the shooting data, and is connected to the transceiver module 38 through the communication module 34, and is connected to the network through the antenna 26; the central processing unit can transmit information to the alarm module 33, using the alarm to scare intruders away from the 5G communication base station. The detection module 44 detects the angle position and sends a signal to the central controller 3. Combined with the drive module 43, it performs drive control. The first motor 15 drives the hinge rod 14 to rotate and adjust inside the bracket 13, and rotates the mounting plate 16 and the swing rod 18 up and down. The alarm module 33 is a laser generator. The laser generated is received by the photoresistor. When a moving object approaches the 5G communication base station, it will block the laser. When the laser is blocked, the photoresistor cannot receive the laser. The electron-hole pairs generated by the photon excitation of the photoresistor on the light alarm will recombine, and the resistance of the photoresistor will return to its original value. When a voltage is applied to the metal electrodes at both ends of the photoresistor, current will flow through it, thereby triggering the sound alarm and the light alarm. The transceiver module 38 connects to the network via the communication module 34 and connects to the server. It combines the big data mode to deeply integrate and compare the images in the captured data with historical big data images, and matches them with real-time change data. It selects big data images with a similarity rate of over 90% to form a comparison result. The comparison result is then matched with the captured data and stored to supplement the historical big data database. It iterative optimization generates a new big data model to complete the judgment of the real-time environment, thereby enabling precise monitoring and control.

[0060] The intelligent monitoring terminal using the 5G communication base station provided in this application has a multi-degree-of-freedom adjustment mechanism inside the opening of the outer shell. This multi-degree-of-freedom adjustment mechanism can drive the monitoring component to perform at least two degrees of freedom of orientation adjustment. This allows the monitoring terminal to actively and flexibly adjust the monitoring angle, thereby adjusting the camera direction as needed in complex and ever-changing monitoring environments, expanding the monitoring coverage and reducing blind spots. This solves the technical problems of existing single-mode cameras with fixed-angle shooting, resulting in small coverage, difficulty in flexible adjustment, and poor environmental adaptability and robustness.
