Description

Technical Field

[0001] The present invention relates to the technical field of monitoring devices, and specifically to an intelligent building security monitoring device. Background Art

[0002] In the field of intelligent building security, the shooting angle coverage ability of monitoring devices directly affects security reliability. In the prior art, although traditional monitoring devices (such as spherical cameras) have a certain vision adjustment function, they generally have the following defects: 1. Limited angle adjustment range: The horizontal and pitch angle adjustment ranges are fixed (usually 360° horizontally and -90° to +90° pitch), and it is impossible to cover all visible line-of-sight directions at the installation position (for example, there are dead corners directly above or below the device). 2. Dependence on multi-device expansion: If it is necessary to expand the monitoring range, multiple cameras need to be deployed additionally, resulting in increased costs and complex installation. 3. Limitations of the mechanical structure: Traditional devices are driven by a single motor to rotate, and it is impossible to simultaneously achieve multi-dimensional coordinated control of horizontal rotation, pitch adjustment, distance adjustment, and fine adjustment of the lens orientation, making it difficult to accurately track dynamic targets. 4. Problem of wire entanglement: The rotating components rely on wires to transmit power and signals, and long-term use is likely to cause failures due to entanglement, affecting the stability of the device. Therefore, there is an urgent need for an intelligent security monitoring device with full-angle coverage, multi-dimensional adjustment, and stable structure. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides an intelligent building security monitoring device, which solves the technical problems existing in the prior art, such as limited shooting angle, dead corners in the shooting angle, and inability to adjust the shooting angle in more directions.

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: An intelligent building security monitoring device, including a mounting base, characterized in that a rotating disk is rotatably installed on the lower wall surface of the mounting base, a pair of shaft brackets are fixedly installed on the lower wall surface of the rotating disk, a driving shaft is fixedly installed on the pair of shaft brackets, an electric roller is fixedly installed on the driving shaft, a rocker arm is fixedly installed on the side wall surface of the electric roller, a telescopic rod is slidably installed in the rocker arm, one end of the telescopic rod is rotatably installed with a U-shaped sleeve, and a monitor is rotatably installed in the U-shaped sleeve.

[0005] Preferably, four mounting through-holes are provided on the mounting base. A servo motor is installed inside the mounting base, and the rotating end of the servo motor is fixedly connected to the upper wall surface of the rotating disk. An annular groove is provided on the lower wall surface of the mounting base, and an annular brush is provided on the upper wall surface of the rotating disk. The annular brush is rotatably installed in the annular groove. The mounting through-holes are used for the fixed connection and installation of the mounting base and the building wall. The power supply and signal transmission of the servo motor, electric roller, controller terminal, electric slide rail, linear motor, drive motor, adjustment motor, and camera are achieved through the metal brush and metal ring arranged in the annular brush and annular groove to form a non-wire transmission, enabling the rotating disk to freely rotate on the mounting base.

[0006] Preferably, a controller terminal is fixedly installed on the side wall surfaces of a pair of the shaft brackets. A roller driving structure is provided inside the electric roller. The roller driving structure includes a roller stator and a roller rotor. The roller stator is fixedly installed outside the driving shaft, and the roller rotor is fixedly installed on the inner wall surface of the electric roller. The controller terminal is internally provided with an Internet signal receiving and transmitting device, an encoder transcoder, and the required information storage device. The roller stator and the roller rotor are controlled and adjusted in terms of angle through servo signals, enabling the rocker arm to rotate around the driving shaft under the control of an operator to complete the adjustment of the pitching angle of the rocker arm. The power supply and subsequent signal transmission are completed through the metal ring provided on the inner wall surface of the electric roller and the metal brush on the fixed shaft.

[0007] Preferably, a limiter is fixedly installed on the rocker arm. The limiter is a rectangular block. Through the limiter, the rotation range of the rocker arm is limited within 180°. When reaching the position limit, the limiter contacts the lower wall surface of the rotating disk.

[0008] Preferably, an electric slide rail is provided inside the rocker arm. A linear motor is fixedly installed on the telescopic rod. The driving end of the linear motor is slidably installed in the electric slide rail. One end of the telescopic rod is fixedly installed with a drive motor. The driving end of the drive motor is fixedly connected to one end of a U-shaped sleeve. The electric slide rail enables the control of the linear motor to drive the extension length of the telescopic rod. Metal strips are provided on the electric slide rail and metal brushes are provided on the telescopic rod for subsequent signal transmission and power supply. The driving end of the drive motor controls the rotation drive of the U-shaped sleeve.

[0009] Preferably, the monitor includes an adjustment motor. The driving end of the adjustment motor is fixedly connected to the inner wall surface of the U-shaped sleeve. A camera is fixedly installed at one end of the adjustment motor. The adjustment motor drives the camera to perform the final angle adjustment. The camera can also be directed towards the inner wall surface of the U-shaped sleeve. This position is the reset position, which can protect the camera lens.

[0010] Preferably, the mounting base is fixed to the building wall by screws passing through the mounting through-holes; the rotating disc is driven by a servo motor, whose servo rotor is fixed to the mounting base and the servo stator is connected to the rotating disc, and the rotating disc is driven by the servo motor to rotate horizontally, so as to realize the planar rotation adjustment of the swing arm.

[0011] Preferably, the pitching angle of the swing arm is driven by the relative rotation of the roller stator and the roller rotor in the electric roller, and the rotation range is limited within degrees by the limiter.

[0012] Preferably, the adjustment of the position and orientation of the camera includes: driving the telescopic rod by a linear motor to adjust the horizontal distance from the drive shaft; respectively controlling the rotation of the U-shaped sleeve and the camera by a drive motor and an adjustment motor; and transmitting image data and control signals through the controller terminal via the Internet.

[0013] An operation method of an intelligent building security monitoring device, installing the mounting base on the fixed building wall surface, threading the screws through the mounting through-holes and connecting them to the threaded holes on the building wall surface to fix the mounting base to fit the building wall surface. The rotational adjustment between the mounting base and the rotating disc is driven by a servo motor. The servo motor installs the servo rotor on the lower wall surface of the fixed disc, installs the servo stator on the upper wall surface of the rotating disc, and fixedly installs the servo encoder in the cover body on the upper wall surface of the mounting base. The driving end of the servo motor rotates to drive the rotating disc to rotate, causing the swing arm to rotate relative to the mounting base. When adjusting the pitching angle of the swing arm relative to the mounting base, it is completed by the relative rotation drive of the roller rotor and the roller stator. The rotation range of the swing arm can be limited within 180° by the limiter. The distance between the camera and the drive shaft is adjusted by the movement of the linear motor in the electric slide rail. The linear motor drives the telescopic rod to slide in the electric slide rail. A drive motor is installed in the telescopic rod to make the U-shaped sleeve rotate around the axis where the telescopic rod is located, and the adjustment motor adjusts the orientation of the camera relative to one end axis of the U-shaped sleeve to adjust the orientation of the camera, so that the camera can collect image data of the position to be observed. The image data information and the control of the monitoring device are transmitted via the Internet through the controller terminal.

[0014] Beneficial effects: The present invention provides an intelligent building security monitoring device. Through a wider camera orientation driving structure, it is convenient to adjust the shooting angle of the security monitoring device. Through the driving adjustment of the speed motor of the mounting base and the rotating disc, the planar rotation angle of the swing arm relative to the mounting base is adjusted. Through the driving of the roller stator and the roller rotor in the electric roller, the pitching angle of the swing arm relative to the mounting base plane is adjusted. The distance between the camera and the drive shaft is adjusted through the telescopic rod and the swing arm, and the shooting direction of the camera is adjusted through the drive motor and the adjustment motor to complete the image shooting of all visible line-of-sight directions of the installation position of the camera. The specific advantages are as follows: 1. Full-angle and dead-angle-free monitoring: Horizontal rotation: The servo motor drives the rotating disk to achieve 360-degree planar rotation, covering the circumferential range of the building; Pitch adjustment: The stator and rotor of the roller in the electric roller drive the rocker arm to pitch (0 - 180 degrees), eliminating the upper and lower visual blind spots of traditional equipment (such as the ceiling directly above the monitoring device or the ground directly below); Fine adjustment of distance and orientation: The telescopic rod adjusts the horizontal distance between the camera and the drive shaft (focusing on details at close range and covering a wide area at long range). In cooperation with the biaxial rotation of the drive motor and the adjustment motor (the axis of the U-shaped sleeve and the axis of the camera), it achieves precise alignment of the viewing angle, ensuring that there are no blind spots in all visible line-of-sight directions at the installation position.

[0015] Non-contact transmission: The ring brush, ring groove, metal strip of the electric slide rail, and metal brush of the telescopic rod form a non-wire transmission system, avoiding malfunctions caused by wire entanglement of rotating components and enhancing the long-term operation stability of the equipment; 2. Mechanical protection and modular design Limit and reset protection: The limiter restricts the rotation range of the rocker arm within 180 degrees to prevent mechanical overload; the camera can be reset to the inner wall of the U-shaped sleeve to protect the lens from external force collision or dust pollution; Single device for multi-scenario adaptation: The monitoring range of traditional multiple cameras is achieved through a set of devices, reducing the number of devices and installation complexity, and lowering the hardware cost and construction difficulty; Dynamic tracking ability: The coordinated control of multiple motors can quickly respond to the movement of the target, adjust the monitoring viewing angle in real time, and improve the tracking efficiency of abnormal events.

[0016] In summary, through structural innovation and intelligent design, the present invention breaks through the angle limitation of traditional monitoring devices, providing a comprehensive, flexible, stable, and reliable solution for building security. Description of the drawings

Through the self-adjustment of the monitoring device, the monitoring device has the ability to monitor all angular directions around the installation position. It is connected to the building wall surface by screwing through the installation through-hole 101, or can be connected to the external flange by bolts and nuts.
